Improving the development, monitoring and reporting of stroke rehabilitation research: Consensus-based core recommendations from the Stroke Recovery and Rehabilitation Roundtable

Co-designing resources for rehabilitation via telehealth for people with moderate to severe disability post stroke

OBJECTIVES

The COVID-19 pandemic necessitated rapid transition to telehealth. Telehealth presents challenges for rehabilitation of stroke survivors with moderate-to-severe physical disability, which traditionally relies on physical interactions. The objective was to co-design resources to support delivery of rehabilitation via telehealth for this cohort.

DESIGN

Four-stage integrated knowledge translation co-design approach. Stage 1: Research team comprising researchers, clinicians and stroke survivors defined the research question and approach. Stage 2: Workshops and interviews were conducted with knowledge users (participants) to identify essential elements of the program. Stage 3: Resources developed by the research team. Stage 4: Resources reviewed by knowledge users and adapted.

PARTICIPANTS

Twenty-one knowledge users (clinicians n = 11, stroke survivors n = 7, caregivers n = 3) RESULTS: All stakeholders emphasised the complexities of telehealth rehabilitation for stroke and the need for individualised programs. Shared decision-making was identified as critical. Potential risks and benefits of telehealth were acknowledged and strategies to ameliorate risks and deliver effective rehabilitation were identified. Four freely available online resources were co-designed; three resources to support clinicians with shared decision-making and risk management and a decision-aid to support stroke survivors and caregivers throughout the process. Over six months, 1129 users have viewed the webpage; clinician resources were downloaded 374 times and the decision-aid was downloaded 570 times.

CONCLUSIONS

The co-design process identified key elements for delivery of telehealth rehabilitation to stroke survivors with moderate-to-severe physical disability and led to development of resources to support development of an individualised telehealth rehabilitation plan. Future research should evaluate the effectiveness of these resources. CONTRIBUTION OF PAPER.

Invaluable Benefits of 10 Years of the International Collaboration of Aphasia Trialists (CATs)

Aphasia research has traditionally been considered a (unidisciplinary) niche topic in medical science. The international Collaboration of Aphasia Trialists (CATs) is a global collaboration of multidisciplinary aphasia researchers. Over the past 10 years, CATs has collectively taken a rigorous approach to systematically address persistent challenges to aphasia research quality. This article summarizes the achievements over the past decade. CATs' achievements include: standardizing terminology, advancing aphasia research design by aphasia expert consensus recommendations, developing a core data set and intervention descriptors, facilitating the involvement of people with the language impairment aphasia in the research process, translating, and adapting assessment tools into global languages, encouraging data sharing, developing innovative secondary data analysis methodologies and promoting the transparency and accessibility of high quality aphasia research reports. CATs' educational and scientific achievements over the past 10 years far exceed what individual researchers in the field could have ever achieved.

The muscle shortening maneuver in individuals with stroke: a consideration-of-concept randomized pilot trial

BACKGROUND AND PURPOSE

The Muscle Shortening Maneuver (MSM) is derived from Feldman's λ model of motor control, and seems to induce a more balanced agonist- antagonist-muscular action. The hypothesized mechanism of action is a modulation of the Tonic Stretch Reflex Threshold (TSRT). We designed a pilot, randomized trial aimed to explore the mechanisms of action of the technique. An ancillary objective was to research the implementation of the MSM as a stroke rehabilitation intervention.

METHODS

A sample of 10 participants with chronic stroke was enrolled and randomly assigned to MSM (n, 5) or conventional physical therapy (CPT) (n, 5) treatments. The TSRTs were assessed by the Montreal Spasticity Measure device. A selection of clinical and instrumental outcome measures was taken to investigate function and activity levels. Data were collected at baseline, end-of-treatment, and one month after the end-of-treatment.

RESULTS

No adverse events were observed. In both between- and within-group post-treatment assessments, in the affected ankle the MSM group showed decreased TSRTs of the plantar flexor, increased strength of the dorsiflexor and active range of motion; also, the time needed to perform the Timed Up and Go test decreased. No changes were evident across assessments in the CPT group.

DISCUSSION AND CONCLUSIONS

The MSM seems able to modulate the TSRTs in individuals with stroke. Although with the limitations due to the pilot design, the variation in participants' responses appear to be promising. Many methodological issues have to be clarified and specified conceiving the progression toward a confirmatory trial.

Intervention to reduce sedentary behaviour and improve outcomes after stroke (Get Set Go): a study protocol for the process evaluation of a pilot cluster randomised controlled trial (RECREATE)

INTRODUCTION

Stroke survivors spend long periods of time engaging in sedentary behaviour (SB) even when their functional recovery is good. In the RECREATE programme, an intervention aimed at reducing SB ('Get Set Go') will be implemented and evaluated in a pragmatic external pilot cluster randomised controlled trial with embedded process and economic evaluations. We report the protocol for the process evaluation which will address the following objectives: (1) describe and clarify causal assumptions about the intervention, and its mechanisms of impact; (2) assess implementation fidelity; (3) explore views, perceptions and acceptability of the intervention to staff, stroke survivors and their carers; (4) establish the contextual factors that influence implementation, intervention mechanisms and outcomes.

METHODS AND ANALYSIS

This pilot trial will be conducted in 15 UK-based National Health Service stroke services. This process evaluation study, underpinned by the Medical Research Council guidance, will be undertaken in six of the randomised services (four intervention, two control). Data collection includes the following: observations of staff training sessions, non-participant observations in inpatient and community settings, semi-structured interviews with staff, patients and carers, and documentary analysis of key intervention components. Additional quantitative implementation data will be collected in all sites. Training observations and documentary analysis data will be summarised, with other observational and interview data analysed using thematic analysis. Relevant theories will be used to interpret the findings, including the theoretical domains framework, normalisation process theory and the theoretical framework of acceptability. Anticipated outputs include the following: recommendations for intervention refinements (both content and implementation); a revised implementation plan and a refined logic model.

ETHICS AND DISSEMINATION

The study was approved by Yorkshire & The Humber - Bradford Leeds Research Ethics Committee (REC reference: 19/YH/0403). Findings will be disseminated via peer review publications, and national and international conference presentations.

Understanding implementation of a complex intervention in a stroke rehabilitation research trial: A qualitative evaluation using Normalisation Process Theory

BACKGROUND

The Implicit Learning in Stroke study was a pilot cluster randomised controlled trial, investigating the use of different motor learning strategies in acute stroke rehabilitation. Participating Stroke Units (n = 8) were from the South East/West regions of the UK, with the experimental intervention (implicit learning) being delivered by clinical teams. It required therapists to change how they gave instructions and feedback to patients during rehabilitation. This paper reports the processes underpinning implementation of the implicit learning intervention. The evaluation aimed to i) understand how therapists made sense of, engaged with and interpreted the effects of the intervention; ii) compare this to the experience reported by patients; iii) extrapolate learning of broader relevance to the design and conduct of research involving complex interventions in stroke rehabilitation.

METHODS

Qualitative evaluation, with data collected through focus groups with clinical staff (n = 20) and semi structured interviews with people with stroke (n = 19). Mixed inductive and theory driven analysis, underpinned by Normalisation Process Theory.

RESULTS

How therapists made sense of and experienced the intervention impacted how it was implemented. The intervention was delivered by individual therapists, and was influenced by their individual values, beliefs and concerns. However, how teams worked together to build a shared (team) understanding, also played a key role. Teams with a more "flexible" interpretation, reported the view that the intervention could have benefits in a wide range of scenarios. Those with a more fixed, "rule based" interpretation, found it harder to implement, and perceived the benefits to be more limited. Therapists' concerns that the intervention may impair therapeutic relationships and patient learning were not reflected in how patients experienced it.

CONCLUSIONS

Changing practice, whether in a research study or in the "real world", is complex. Understanding the process of implementation is crucial to effective research delivery. Implementation frameworks facilitate understanding, and subsequently the systematic and iterative development of strategies for this to be addressed. How teams (rather than individuals) work together is central to how complex interventions are understood and implemented. It is possible that new complex interventions work best in contexts where there are 'flexible' cultures. Researchers should consider, and potentially measure this, before they can effectively implement and evaluate an intervention.

How little is enough? The feasibility of conducting a dose-escalation study for exercise training in people with stroke

QUESTION

Is it feasible and safe to conduct an exercise dose-finding study in people with stroke? Is it possible to determine a minimal dose of exercise required to see clinically meaningful improvements in cardiorespiratory fitness?

METHODS

Dose-escalation study. Twenty people with stroke (n=5 per cohort) who were able to walk independently participated in home-based, telehealth-supervised aerobic exercise sessions 3 d/week at moderate-vigorous intensity for 8 weeks. Dose parameters of frequency (3 d/week), intensity (55-85% of heart rate peak) and program length (8 weeks) were kept constant. The duration of exercise sessions was increased by 5 min per session from Dose 1 (10 min/session) to Dose 4 (25 min/session). Doses were escalated if safe and tolerable (< 33% of a cohort reaching a dose-limiting threshold). Doses were efficacious if ≥ 67% of a cohort increased peak oxygen consumption ≥ 2mL/kg/min.

RESULTS

Target exercise doses were well adhered to, and the intervention was safe (480 exercise sessions delivered; one fall resulting in minor laceration) and tolerable (no participants met the dose-limiting threshold). None of the exercise doses met our criterion for efficacy.

CONCLUSIONS

It is possible to conduct a dose-escalation trial for people with stroke. The small cohort sizes may have limited the ability to determine an efficacious minimum dose of exercise. Providing supervised exercise session at these prescribed doses via telehealth was safe.

REGISTRATION

The study was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12617000460303).

The role of the physical environment in stroke recovery: Evidence-based design principles from a mixed-methods multiple case study

Hospital design can impact patient outcomes, but there is very little healthcare design evidence specific to stroke rehabilitation facilities. Our aim was to explore, from the patient perspective, the role of the physical environment in factors crucial to stroke recovery, namely, stroke survivor activity (physical, cognitive, social), sleep, emotional well-being, and safety. We conducted a mixed-methods multiple-case study at two inpatient rehabilitation facilities in Victoria, Australia, (n = 20 at Case 1, n = 16 at Case 2) using "walk-through" semi-structured interviews, behavioural mapping, questionnaires, and retrospective audit. Four interrelated themes emerged: 1) entrapment and escape; 2) power, dependency, and identity in an institutional environment; 3) the rehabilitation facility is a shared space; and 4) the environment should be legible and patient-centred. Quantitative data revealed patterns in patient activity; stroke survivors spent over 75% of their time in bedrooms and were often inactive. Convergent mixed methods analysis was used to generate a new conceptual model of the role of the physical environment in stroke survivors' behaviour and well-being, highlighting the importance of variety and interest, privacy without isolation, and patient-centred design. This model can be used by designers, healthcare providers, and policy makers to inform the design of rehabilitation environments.

Virtual reality in post-stroke neurorehabilitation - a systematic review and meta-analysis

BACKGROUND

Stroke is a neurological disorder and one of the leading causes of disability worldwide. The patient may lose the ability to adequately move the extremities, perceive sensations, or ambulate independently. Recent experimental studies have reported the beneficial influence of virtual reality training strategies on improving overall functional abilities for stroke survivors.

METHODS

Conducted a systematic review of the literature using the following keywords to retrieve the data: stroke, virtual reality, motor deficits, neurorehabilitation, cognitive impairments, and sensory deficits. A random-effect meta-analysis was performed for seven scales - one cognitive (MMSE) and six motor (Fugl-Meyer, Berg Balance Scale, Time up and go, Wolf motor function, 10 m walk, Brunnstrom score).

OBJECTIVE

To organize and compare all the available data regarding the effectiveness of virtual reality for stroke rehabilitation.

RESULTS

This literature reviewed 150 studies and included 46 for qualitative and 27 for quantitative analysis. There was no statistically significant difference between groups in MMSE score (MD = 0.24, 95%CI = ((-0.42) -(0.9)), p = .47, I² = 0%) and Fugl-Meyer score (MD = (-0.38), 95%CI = ((-12.88)-(12.11)), p = .95, I² = 98%) . The statistical significance was not reached in any of the other outcomes.

CONCLUSIONS

This review supports that stroke rehabilitation programs incorporating virtual reality are associated with improved functional outcomes, but there is no statistically significant difference compared to standard therapy.

Scoping review protocol of the use of codesign methods in stroke intervention development

INTRODUCTION

Codesign is an emerging research method to enhance intervention development by actively engaging non-researchers (eg, people who have had a stroke, caregivers and clinicians) in research. The involvement of non-researchers in research is becoming increasingly popular within health studies as it may produce more relevant and effective findings. The stroke population commonly exhibits challenges such as aphasia and cognitive changes that may limit their participation in codesign. However, the use of codesign within the stroke literature has not been comprehensively reviewed. This scoping review will determine: (1) what is the extent, range and nature of stroke research that has used codesign methods? (2) What codesign methods have been used to develop stroke interventions? (3) What considerations for codesigning interventions with people who have stroke are not captured in the findings?

METHODS AND ANALYSIS

This is a protocol for a scoping review to identify the literature relating to stroke, and codesign will be conducted on OVID Medline, OVID Embase, OVID PsychINFO, EBSCO CINAHL, the Cochrane Library, Scopus, PEDro-Physiotherapy Evidence Database and Global Index Medicus. Studies of any design and publication date will be included. Title and abstract and full-text review will be conducted independently by two reviewers. Data will be extracted, collated and then summarised descriptively using quantitative (eg, numerical descriptions) and qualitative (eg, textual descriptions) methods. Numerical summaries will map the extent (eg, number of studies), range (eg, types of studies) and nature (eg, types of interventions developed) of the literature on this topic. A thematic analysis will provide insights into the codesign methods (eg, activities, non-researchers), including heterogeneity across and within studies.

ETHICS AND DISSEMINATION

This review protocol does not require ethics approval as data has not been collected/analysed. The findings will highlight opportunities and recommendations to inform future codesign research in stroke and other populations who exhibit similar challenges/disabilities, and they will be disseminated via publications, presentations and stakeholder meetings.

Developing an implementation fidelity checklist for a vocational rehabilitation intervention

BACKGROUND

Despite growing numbers of studies reporting the efficacy of complex interventions and their implementation, many studies fail to report information on implementation fidelity or describe how fidelity measures used within the study were developed. This study aimed to develop a fidelity checklist for measuring the implementation fidelity of an early, stroke-specialist vocational rehabilitation intervention (ESSVR) in the RETAKE trial.

METHODS

To develop the fidelity measure, previous checklists were reviewed to inform the assessment structure, and core intervention components were extracted from intervention descriptions into a checklist, which was ratified by eight experts in fidelity measurement and complex interventions. Guidance notes were generated to assist with checklist completion. To test the measure, two researchers independently applied the checklist to fifteen stroke survivor intervention case notes using retrospective observational case review. The scoring was assessed for interrater reliability.

RESULTS

A fidelity checklist containing 21 core components and 6 desirable components across 4 stages of intervention delivery was developed with corresponding guidance notes. Interrater reliability of each checklist item ranged from moderate to perfect (Cohen's kappa 0.69-1).

CONCLUSIONS

The resulting checklist to assess implementation fidelity is fit for assessing the delivery of vocational rehabilitation for stroke survivors using retrospective observational case review. The checklist proved its utility as a measure of fidelity and may be used to inform the design of future implementation strategies.

Upper-Limb Motor Intervention Elements That Drive Improvement in Biomarkers and Clinical Measures Post-Stroke: A Systematic Review in a Systems Paradigm

Objective

To use a systems paradigm to examine upper limb (UL) motor intervention elements driving biomarker and clinical measure improvement after stroke.

Methods

Databases were searched up to March 2022. Eligibility screening was completed by 2 authors. Studies using biomarkers and clinical measures pre- and post-upper limb intervention were included. Studies of adjunct interventions (eg, brain stimulation) were excluded. Cochrane Risk-of-Bias tools and Template for Intervention Description and Replication were used to rate studies. Studies were synthesized using a systems paradigm: intervention outcome was considered an emergent property of the systemic interactions of 4 intervention elements (demographics, type, quality, and dose) characterized by individual dimensions.

Results

Sixty-four studies (n = 1814 participants) containing 106 intervention groups (66 experimental; 40 control) were included. Combined biomarker and clinical outcomes defined 3 scenarios: restitution, mixed, and unchanged. The restitution scenario included more moderate-to-severely impaired participants in earlier recovery phases (<6 months). Interventions with graded difficulty were more frequently used in the restitution scenario compared with the unchanged scenario. No difference in quality or amount of therapy was identified when examining scenarios that demonstrated restitution compared to those that did not (mixed and unchanged).

Conclusions

A systems paradigm may be one of many approaches to understand UL motor restitution. This review found no single element consistently delivered improvements in biomarkers and clinical measures in the examined intervention groups. Complex patterns formed by multiple interacting intervention elements were observed in participants with and without restitution.

Developing a method to assess fidelity to a complex vocational rehabilitation intervention in the FRESH trial: a feasibility study

Background

Determining whether complex rehabilitation interventions are delivered with fidelity is important. Implementation fidelity can differ between sites, therapists delivering interventions and, over time, threatening trial outcomes and increasing the risk of type II and III errors. This study aimed to develop a method of assessing occupational therapists’ fidelity to deliver a complex, individually tailored vocational rehabilitation (VR) intervention to people with traumatic brain injury (TBI) and assess the feasibility of its use in a randomised controlled trial.

Methods

Using mixed methods and drawing on the intervention logic model, we developed data collection tools to measure fidelity to early specialist TBI VR (ESTVR). Fidelity was measured quantitatively using intervention case report forms (CRF), fidelity checklists and clinical records. Qualitative data from mentoring records, interviews with intervention therapists, participants with TBI, employers and NHS staff at trial sites explored moderators of implementation fidelity. The conceptual framework of implementation fidelity (CFIF) guided measurement and analysis of and factors affecting fidelity. Data were triangulated and benchmarked against an earlier cohort study.

Results

Fidelity to a complex individually tailored VR intervention could be measured. Overall, OTs delivered ESTVR with fidelity. Different fidelity measures answered different questions, offering unique insights into fidelity. Fidelity was best assessed using a fidelity checklist, intervention CRFs and clinical notes. The OT clinical notes and mentoring records were best at identifying fidelity moderating factors. Interviews added little insight into fidelity moderating factors over and above mentoring or clinical records. Data triangulation offered a comprehensive assessment of fidelity, highlighting limitations of measurement methods and learning for future trials but was resource intensive. Interviews, fidelity visits and analysing clinical notes were also resource intense. Comparing fidelity data to a benchmark and using CFIF as a framework for organising the fidelity assessment helped.

Conclusions

OTs delivered the VR intervention with fidelity. A fidelity checklist and benchmark plus mentoring may offer a practical and effective way of measuring fidelity and identifying fidelity moderating factors in trials of complex individually-tailored rehabilitation interventions. Mentoring provided real-time indicators of and reasons for fidelity deviations. These methods require further evaluation.

A Large-Scale Prospective Study on Functional Ability and Mortality Following Stroke Based on HRS Data Set: Implications for Rehabilitation

According to the WHO, 15 million people worldwide suffer a stroke annually. Of these, 5 million die and another 5 million are left permanently disabled. Patients endure the impacts of strokes during their rehabilitation and afterward, placing economical and emotional burdens on family and community. Using data from the Health and Retirement Study (HRS) of the USA, the research performed a large-scale prospective analysis to examine how demographics, socioeconomic factors, cognition, emotion, and physical activity predict functional impairment and mortality. Multiple regression was employed to identify statistically significant variables that predict longitudinal Activities of Daily Life (ADLs). The least absolute shrinkage and selection operator (LASSO) logistic regression, a supervised machine learning approach, was deliberately chosen to obtain the subset of predictors that provide the best possible classification for the dependent variable. The LASSO regression produced a model with a fair mean Area Under the Curve (AUC) of 0.75 in predicting the risk of the patient's mortality. My findings also uncovered the important roles of BMI, mobility, muscle strength, memory, mental status, and socioeconomic status play in the long-term ADLs and survival of patients with stroke.

Scientific basis and active ingredients of current therapeutic interventions for stroke rehabilitation

Background: Despite tremendous advances in the treatment and management of stroke, restoring motor and functional outcomes after stroke continues to be a major clinical challenge. Given the wide range of approaches used in motor rehabilitation, several commentaries have highlighted the lack of a clear scientific basis for different interventions as one critical factor that has led to suboptimal study outcomes. Objective: To understand the content of current therapeutic interventions in terms of their active ingredients. Methods: We conducted an analysis of randomized controlled trials in stroke rehabilitation over a 2-year period from 2019-2020. Results: There were three primary findings: (i) consistent with prior reports, most studies did not provide an explicit rationale for why the treatment would be expected to work, (ii) most therapeutic interventions mentioned multiple active ingredients and there was not a close correspondence between the active ingredients mentioned versus the active ingredients measured in the study, and (iii) multimodal approaches that involved more than one therapeutic approach tended to be combined in an ad-hoc fashion, indicating the lack of a targeted approach. Conclusion: These results highlight the need for strengthening cross-disciplinary connections between basic science and clinical studies, and the need for structured development and testing of therapeutic approaches to find more effective treatment interventions.

RETurn to work After stroKE (RETAKE) Trial: protocol for a mixed-methods process evaluation using normalisation process theory

OBJECTIVES

This mixed-method process evaluation underpinned by normalisation process theory aims to measure fidelity to the intervention, understand the social and structural context in which the intervention is delivered and identify barriers and facilitators to intervention implementation.

SETTING

RETurn to work After stroKE (RETAKE) is a multicentre individual patient randomised controlled trial to determine whether Early Stroke Specialist Vocational Rehabilitation (ESSVR) plus usual care is a clinically and cost-effective therapy to facilitate return to work after stroke, compared with usual care alone. This protocol paper describes the embedded process evaluation.

PARTICIPANTS AND OUTCOME MEASURES

Intervention training for therapists will be observed and use of remote mentor support reviewed through documentary analysis. Fidelity will be assessed through participant questionnaires and analysis of therapy records, examining frequency, duration and content of ESSVR sessions. To understand the influence of social and structural contexts, the process evaluation will explore therapists' attitudes towards evidence-based practice, competency to deliver the intervention and evaluate potential sources of contamination. Longitudinal case studies incorporating non-participant observations will be conducted with a proportion of intervention and usual care participants. Semistructured interviews with stroke survivors, carers, occupational therapists, mentors, service managers and employers will explore their experiences as RETAKE participants. Analysis of qualitative data will draw on thematic and framework approaches. Quantitative data analysis will include regression models and descriptive statistics. Qualitative and quantitative data will be independently analysed by process evaluation and Clinical Trials Research Unit teams, respectively. Linked data, for example, fidelity and describing usual care will be synthesised by comparing and integrating quantitative descriptive data with the qualitative findings.

The Development of an Early Intervention for Supporting Families of Persons With Acquired Brain Injuries: The SAFIR© Intervention

Families of persons with acquired brain injuries need to be supported from the early phase of hospitalization. To date, no known early family intervention is available for this population. Using the Medical Research Council Framework, we developed a new intervention based on the Calgary Assessment and Intervention Models that includes the family preferences, clinician's expertise, and the contextual resources. This paper aims to describe the complete development process including a scoping review, an assessment of families and clinicians' needs, an evaluation of the contextual resources, and an adaptation of the theoretical framework. Using a systemic perspective, we tailored the new intervention to involve the stakeholder's preferences. The result is an early family intervention named SAFIR^©, led by a clinical nurse specialist, including five core components and structured around three phases and a follow-up. The next steps will be focused on assessment of the clinical feasibility of this new intervention.

Corticocortical paired associative stimulation for treating motor dysfunction after stroke: study protocol for a randomised sham-controlled double-blind clinical trial

INTRODUCTION

Stroke survivors can have a high disability rate with low quality of daily life, resulting in a heavy burden on family and society. Transcranial magnetic stimulation has been widely applied to brain injury repair, neurological disease treatment, cognition and emotion regulation and so on. However, there is still much to be desired in the theories of using these neuromodulation techniques to treat stroke-caused hemiplegia. It is generally recognised that synaptic plasticity is an important basis for functional repair after brain injury. This study protocol aims to examine the corticocortical paired associative stimulation (ccPAS) for inducing synaptic plasticity to rescue the paralysed after stroke.

METHODS AND ANALYSIS

The current study is designed as a 14-week double-blind randomised sham-controlled clinical trial, composed of 2-week intervention and 12-week follow-up. For the study, 42 patients who had a stroke aged 40-70 will be recruited, who are randomly assigned either to the ccPAS intervention group, or to the control group at a 1:1 ratio, hence an equal number each. In the intervention group, ccPAS is practised in conjunction with the conventional rehabilitation treatment, and in the control group, the conventional rehabilitation treatment is administered with sham stimulation. A total of 10 interventions will be made, 5 times a week for 2 weeks. The same assessors are supposed to evaluate the participants' motor function at four time points of the baseline (before 10 interventions), treatment ending (after 10 interventions), and two intervals of follow-up (1 and 3 months later, respectively). The Fugl-Meyer Assessment Upper Extremity is used for the primary outcomes. The secondary outcomes include changes in the assessment of Action Research Arm Test (ARAT), Modified Barthel Index (MBI), electroencephalogram (EEG) and functional MRI data. The adverse events are to be recorded throughout the study.

ETHICS AND DISSEMINATION

This study was approved by the Medical Ethics Committee of Yueyang Hospital. All ethical work was performed in accordance with the Helsinki declaration. Written informed consent was obtained from all individual participants included in the study. Study findings will be disseminated in the printed media.

A Biopsychosocial Intervention for Stroke Carers (BISC): development and description of the intervention

Objective

Family members of stroke survivors are often not supported for their caring role, with many reporting adjustment difficulties. This paper describes the development and content of a group-based intervention for informal carers of stroke survivors.

Method

The intervention is based on the theoretical foundation of the biopsychosocial model with the aim to understand and address the physical, psychological and social factors of caring for stroke survivors. Findings from a comprehensive literature review and a qualitative study with carers and stroke professionals were synthesized to guide the intervention development. The Template for Intervention Description and Replication (TIDieR) checklist was used as a framework to describe the intervention.

Results

The intervention integrates cognitive-behavioural approaches via the identification of the biopsychosocial (physical, emotional, social) factors that can have an impact on the well-being of carers. It includes education on stroke-specific topics and advice on coping strategies. It consists of six structured two-hour group sessions facilitated in a community setting. It provides information and support on adjusting to the caring role in the first year post-stroke. Intervention materials were designed for addressing carers’ specific needs using psychological techniques, such as problem-solving, goal setting and relaxation exercises.

Conclusion

We have underlined the importance for describing and reporting the process of intervention development for complex interventions in the context of stroke rehabilitation. An intervention addressing the needs of informal stroke carers (Biopsychosocial Intervention for Stroke Carers; BISC) has been developed and described. BISC was further evaluated in a single-centre feasibility randomized controlled trial.

Co-Designing a New Yoga-Based Mindfulness Intervention for Survivors of Stroke: A Formative Evaluation

Movement-based mindfulness interventions (MBI) are complex, multi-component interventions for which the design process is rarely reported. For people with stroke, emerging evidence suggests benefits, but mainstream programs are generally unsuitable. We aimed to describe the processes involved and to conduct a formative evaluation of the development of a novel yoga-based MBI designed for survivors of stroke. We used the Medical Research Council complex interventions framework and principles of co-design. We purposefully approached health professionals and consumers to establish an advisory committee for developing the intervention. Members collaborated and iteratively reviewed the design and content of the program, formatted into a training manual. Four external yoga teachers independently reviewed the program. Formative evaluation included review of multiple data sources and documentation (e.g., formal meeting minutes, focus group discussions, researcher observations). The data were synthesized using inductive thematic analysis. Three broad themes emerged: (a) MBI content and terminology; (b) manual design and readability; and (c) barriers and enablers to deliver the intervention. Various perspectives and feedback on essential components guided finalizing the program. The design phase of a novel yoga-based MBI was strengthened by interdisciplinary, consumer contributions and peer review. The 12-week intervention is ready for testing among survivors of stroke.

Examining the effects of upper extremity function and arm sling type on balance, gait and fall risk in patients with hemiparesis

Background/aims

Previous studies have reported conflicting results on the effects of arm slings on the balance and gait of patients with hemiparesis. These previous studies did not consider the ability to control the upper extremity on the affected side as a factor that could affect the patient's balance or gait when an arm sling was applied. Hence, the aim of this study was to investigate the effect of upper extremity function in the affected side and arm position according to the sling type on balance, gait and fall.

Methods

A total of 31 stroke patients participated in the study and were assigned to two groups according to upper extremity function (low-score group and high-score group). Under three conditions (no sling, forearm sling and shoulder sling), a fall risk test, postural stability test and limits of stability test were performed and speed, stride duration, step length and total time were measured.

Results

When the high-score group wore forearm slings, the static and dynamic balance ability decreased and the fall risk increased. When the low-score group wore forearm slings and shoulder slings, the static and dynamic balance ability increased and the fall risk decreased. The high-score group had a shorter gait time when wearing shoulder slings. When the low-score group wore forearm slings, the speed and step length increased and the total time decreased, enhancing the overall gait ability.

Conclusions

For stroke patients with better upper extremity control ability, shoulder slings are more appropriate. For patients with poor upper extremity control ability, forearm slings are more appropriate. Using the appropriate sling according to the upper extremity function can improve balance and gait ability and fall risk can be reduced.

Development of a self-management intervention for stroke survivors with aphasia using co-production and behaviour change theory: An outline of methods and processes

Background

Self-management is a promising approach to improve quality of life after stroke. However, evidence for the appropriateness and effectiveness of self-management for stroke survivors with aphasia is limited. This article reports on the process used to develop a supported self-management intervention for stroke survivors with aphasia (SSWA) using co-production and behaviour change theory. Preparatory research included systematic reviews, and qualitative interviews and focus groups with SSWA, family members and speech and language therapists (SLTs).

Materials and methods

We conducted six, 2 hour long intervention development workshops with key stakeholders. The workshops were informed by principles of co-production and the intervention development process outlined by the Behaviour Change Wheel (BCW). We also incorporated the findings of our preparatory research within workshops. Each workshop included an introduction, 1–2 co-production tasks and time for feedback at the end of the session. Data were analysed on an ongoing basis so that findings could be used to feed in to subsequent workshops and intervention development.

Results

Workshop participants (n = 12) included; SSWA (n = 5), family members (n = 3) and SLTs (n = 4). Together, participants engaged with accessible and participatory co-production tasks which aligned with the BCW framework. Participants engaged in discussion to define self-management in behavioural terms (behavioural diagnosis) and to identify what needed to change to support self-management. Participant’s co-produced solutions for supporting self-management and discussed options to implement these in practice. Prototype materials were generated by the research team and evaluated by participants. Intervention functions and behaviour change techniques (BCTs) were mapped to the solutions generated by participants by the research team, after the final workshop. A supported self-management intervention for SSWA was developed which will be delivered by SLTs through community stroke services.

Conclusions

This paper reports the process we used to integrate co-production work with behaviour change theory to develop a complex self-management intervention. This is of relevance for researchers looking to harness the strengths of co-production methods and theory in intervention design. Future research will feasibility test the supported self-management intervention developed. This paper provides transparency to our intervention development process which will help others to better interpret the findings of our feasibility work.

Treatment fidelity of technology-enhanced reading therapy (CommuniCATE) for people with aphasia

BACKGROUND

Treatment fidelity (TF), that is, the degree to which the treatment delivery has adhered to protocol, is an important aspect of establishing treatment validity and reliability. Research has shown that establishing TF is only done in a small percentage of aphasia treatment studies.

AIMS

This project supports the work of the CommuniCATE study, which explored the benefits of technology-enhanced aphasia therapy on participants' reading, writing, speech and conversation skills. It examines the TF of the Reading strand of the CommuniCATE project by assessing whether the therapy adhered to the protocol. The following research questions were asked: Does treatment delivery adhere to treatment protocol? Does the degree of TF vary according to the person delivering the therapy (i.e. student therapist or qualified therapist)? Does the degree of TF vary over time (early treatment sessions compared with later treatment sessions)? Was the checklist tool reliable?

METHODS & PROCEDURES

This study assessed the fidelity of 38 retrospective video recordings of therapy. It used a checklist measure of criteria to which the delivery of the sessions should adhere, and against which the sessions were rated. Participants were the people with aphasia receiving therapy, the students and qualified speech and language therapists delivering therapy, and the independent raters assessing the sessions. A sample of sessions was randomly chosen, including sessions delivered by qualified therapists and by students, and sessions from different time points in the treatment process. The fidelity was rated by the first author, and the fidelity rating calculated as a percentage. Comparisons in fidelity scores for the different variables were drawn using Mann-Whitney tests. The reliability of the checklist was assessed through inter and intra-rater reliability testing, and the results were analysed using Kappa statistics.

OUTCOMES & RESULTS

High fidelity was found across all therapy conditions with a mean score of 98.2%. Fidelity scores were not affected by the administrator of therapy; sessions delivered by qualified and student therapists were rated equally highly. There was a small but significant effect of time, with later treatment sessions scoring more highly than earlier sessions. However, scores across both periods > 90%. Inter-rater reliability found a high percentage agreement of 93.3% and a Poor Kappa agreement level. Intra-rater agreement found a high percentage agreement of 97.3% and a Fair Kappa agreement level.

CONCLUSIONS & IMPLICATIONS

The CommuniCATE reading therapy was implemented as per the protocol across time points, and withstood delegation to students. The high fidelity and good reliability scores have positive implications for the study's validity and reliability, and for the study's replication.

WHAT THIS PAPER ADDS

What is already known on the subject TF refers to the degree to which the delivery of core components of a treatment matches the implementation guidelines, that is, the adherence to protocol. Despite the acknowledged importance of TF reporting, this is often neglected in the literature. What this paper adds to existing knowledge This paper shows that the TF assessment of the CommuniCATE study (reading strand) found a 98.2% fidelity score, and that high fidelity was not compromised across treatment conditions. This paper outlines the principles of TF and highlights the need for measures to be in place to establish TF, for example, manuals, training and supervision; and to monitor TF, for example, via the use of checklists. This paper also underlines the scarcity of TF measures and checks in aphasia research. This paper therefore serves as a model of TF practice in aphasia therapy research. What are the potential or actual clinical implications of this work? This study contributes to the findings of the CommuniCATE project (reading strand), and the high fidelity findings enhance the validity of the project and indicate that the therapy manual and training enable accurate implementation of delivery. This paper also contributes to the literature on TF evaluation in aphasia studies, which is presently lacking, and highlights the need for increased focus on the optimum strategies of TF reporting.

Timing and Dose of Upper Limb Motor Intervention After Stroke: A Systematic Review

This systematic review aimed to investigate timing, dose, and efficacy of upper limb intervention during the first 6 months poststroke. Three online databases were searched up to July 2020. Titles/abstracts/full-text were reviewed independently by 2 authors. Randomized and nonrandomized studies that enrolled people within the first 6 months poststroke, aimed to improve upper limb recovery, and completed preintervention and postintervention assessments were included. Risk of bias was assessed using Cochrane reporting tools. Studies were examined by timing (recovery epoch), dose, and intervention type. Two hundred and sixty-one studies were included, representing 228 (n=9704 participants) unique data sets. The number of studies completed increased from one (n=37 participants) between 1980 and 1984 to 91 (n=4417 participants) between 2015 and 2019. Timing of intervention start has not changed (median 38 days, interquartile range [IQR], 22-66) and study sample size remains small (median n=30, IQR 20-48). Most studies were rated high risk of bias (62%). Study participants were enrolled at different recovery epochs: 1 hyperacute (<24 hours), 13 acute (1-7 days), 176 early subacute (8-90 days), 34 late subacute (91-180 days), and 4 were unable to be classified to an epoch. For both the intervention and control groups, the median dose was 45 (IQR, 600-1430) min/session, 1 (IQR, 1-1) session/d, 5 (IQR, 5-5) d/wk for 4 (IQR, 3-5) weeks. The most common interventions tested were electromechanical (n=55 studies), electrical stimulation (n=38 studies), and constraint-induced movement (n=28 studies) therapies. Despite a large and growing body of research, intervention dose and sample size of included studies were often too small to detect clinically important effects. Furthermore, interventions remain focused on subacute stroke recovery with little change in recent decades. A united research agenda that establishes a clear biological understanding of timing, dose, and intervention type is needed to progress stroke recovery research.

Embedding mentoring to support trial processes and implementation fidelity in a randomised controlled trial of vocational rehabilitation for stroke survivors

BACKGROUND

Little guidance exists regarding how best to upskill and support those delivering complex healthcare interventions to ensure robust trial outcomes and implementation fidelity. Mentoring was provided to occupational therapists (OTs) delivering a complex vocational rehabilitation (VR) intervention to stroke survivors. This study aimed to explore mentors' roles in supporting OTs with intervention delivery and fidelity, and to describe factors affecting the mentoring process and intervention delivery.

METHODS

Quantitative data (duration, mode and total time of mentoring support) was extracted from mentoring records and emails between mentors and OTs, alongside qualitative data on barriers and facilitators to intervention delivery. Semi-structured interviews with mentors (n = 6) and OTs (n = 19) explored experiences and perceptions of intervention training, delivery and the mentoring process. Mean total and monthly time spent mentoring were calculated per trial site. Qualitative data were analysed thematically.

RESULTS

Forty-one OTs across 16 sites were mentored between March 2018 and April 2020. Most mentoring was provided by phone or Microsoft Teams (range: 88.6-100%), with the remainder via email and SMS (Short Message Service) text messages. Mentors suggested strategies to enhance trial recruitment, improved OTs' understanding of- and adherence to trial processes, intervention delivery and fidelity, and facilitated independent problem-solving. Barriers to mentoring included OT non-attendance at mentoring sessions and mentors struggling to balance mentoring with clinical roles. Facilitators included support from the trial team and mentors having protected time for mentoring.

CONCLUSIONS

Mentoring supported mentee OTs in various ways, but it remains unclear to what extent the OTS would have been able to deliver the intervention without mentoring support, or how this might have impacted fidelity. Successful implementation of mentoring alongside new complex interventions may increase the likelihood of intervention effectiveness being observed and sustained in real-life contexts. Further research is needed to investigate how mentors could be selected, upskilled, funded and mentoring provided to maximise impact. The clinical- and cost-effectiveness of mentoring as an implementation strategy and its impact on fidelity also requires testing in a future trial.

Using Intervention Mapping to develop and implement a home-based sedentary behavior change intervention after stroke

Prolonged sedentary behavior is a problem immediately following a stroke and it persists from the acute to chronic phases of recovery. Frequently interrupting sedentary time might help to mitigate the associated detrimental health consequences. The purpose of this article was to describe the process followed in the systematic development and implementation of a theory- and home-based sedentary behavior change intervention for people with stroke. The Intervention Mapping protocol was used to design, develop and implement a STand Up Frequently From Stroke (STUFFS) program aimed at reducing prolonged sedentary behavior after stroke. A qualitative inquiry with people with stroke (n = 13) informed the development of the intervention. The systematic approach followed in the development process including the theoretical basis, content development, and evaluation planning were described. Program reception was assessed using thematic content analysis of exit-interview data (n = 25). The 8-weeks STUFFS intervention is a home-based sedentary behavior change program that provides education about the risks of prolonged sedentary behavior and facilitates behavior change, including the use of motivational tools to empower people with stroke to reduce sedentary behavior. The program was well-received and acceptable to people with stroke (89% satisfaction). This article provides information that furthers knowledge about theory-based strategies to reduce sedentary behavior in the home environment after stroke and facilitates implementation of this type of intervention.

SUpporting wellbeing through PEeR-Befriending (SUPERB) feasibility trial: fidelity of peer-befriending for people with aphasia

OBJECTIVE

To evaluate systematically the fidelity of a peer-befriending intervention for people with aphasia.

DESIGN

SUpporting wellbeing through Peer-befriending (SUPERB) was a feasibility randomised controlled trial comparing usual care to usual care +peer-befriending. This paper reports on the fidelity of all intervention aspects (training and supervision of providers/befrienders; intervention visits) which was evaluated across all areas of the Behaviour Change Consortium framework.

SETTING

Community.

PARTICIPANTS

People with aphasia early poststroke and low levels of distress, randomised to the intervention arm of the trial (n=28); 10 peer-befrienders at least 1-year poststroke.

INTERVENTION

Peer-befrienders were trained (4-6 hours); and received regular supervision (monthly group while actively befriending, and one-to-one as and when needed) in order to provide six 1-hour peer-befriending visits over 3 months.

MAIN MEASURES

Metrics included number and length of training, supervision sessions and visits. All training and supervision sessions and one (of six) visits per pair were rated against fidelity checklists and evaluated for inter-rater and intrarater reliability (Gwets AC1 agreement coefficient). Per-cent adherence to protocol was evaluated.

RESULTS

All peer-befrienders received 4-6 hours training over 2-3 days as intended. There were 25 group supervision sessions with a median number attended of 14 (IQR=8-18). Twenty-six participants agreed (92.8%) to the intervention and 21 (80.8%) received all six visits (median visit length 60 min). Adherence was high for training (91.7%-100%) and supervision (83%-100%) and moderate-to-high for befriending visits (66.7%-100%). Where calculable, inter-rater and intrarater reliability was high for training and supervision (Gwets AC1 >0.90) and moderate-to-high for intervention visits (Gwets AC1 0.44-1.0).

CONCLUSION

Planning of fidelity processes at the outset of the trial and monitoring throughout was feasible and ensured good-to-high fidelity for this peer-befriending intervention. The results permit confidence in other findings from the SUPERB trial.

Fidelity assessment of nurse-led non-pharmacological package of care for knee pain in the package development phase of a feasibility randomised controlled trial based in secondary care: a mixed methods study

OBJECTIVES

To evaluate fidelity of delivery of a nurse-led non-pharmacological complex intervention for knee pain.

SETTING

Secondary care. Single-centre study.

STUDY DESIGN

Mixed methods study.

PARTICIPANTS

Eighteen adults with chronic knee pain.

INCLUSION CRITERIA

Age >40 years, knee pain present for longer than 3 months, knee pain for most days of the previous month, at least moderate pain in two of the five domains of Western Ontario and McMaster Universities Osteoarthritis Index pain scale.

INTERVENTIONS

Nurse-led non-pharmacological intervention comprising assessment, education, exercise, use of hot/cold treatments, footwear modification, walking aids and weight-loss advice (if required).

OUTCOMES

Primary: fidelity of delivery of intervention, secondary: nurses' experience of delivering intervention.

METHODS

Each intervention session with every participant was video recorded and formed part of fidelity assessment. Fidelity checklists were completed by the research nurse after each session and by an independent researcher, after viewing the video-recordings blinded to nurse ratings. Fidelity scores (%), percentage agreement and 95% Confidence Intervals (CI) were calculated. Two semi-structured interviews were conducted with the research nurse.

RESULTS

Fourteen participants completed all visits. 62 treatment sessions took place. Nurse self-report and assessor video rating scores for all 62 treatment sessions were included in fidelity assessment. Overall fidelity was higher on nurse self-report (97.7%) than on objective video-rating (84.2%). Percentage agreement between nurse self-report and video-rating was 73.3% (95% CI 71.3 to 75.3). Fidelity was lowest for advice on footwear and walking aids. The nurse reported difficulty advising on thermal treatments, footwear and walking aids, and did not feel confident negotiating achievable and realistic goals with participants.

CONCLUSIONS

A trained research nurse can deliver most components of a non-pharmacological intervention for knee pain to a high degree of fidelity. Future research should assess intervention fidelity in a routine clinical setting, and examine its clinical and cost-effectiveness.

Secondary Prevention of Stroke: Study Protocol for a Telehealth-Delivered Physical Activity and Diet Pilot Randomized Trial (ENAbLE-Pilot)

BACKGROUND

Increasing physical activity (PA) and improving diet quality are opportunities to improve secondary stroke prevention, but access to appropriate services is limited. Interventions co-designed with stroke survivors and delivered by telehealth are a potential solution.

AIM

The aim of this study is to test the feasibility, safety, and potential efficacy of a 6-month, telehealth-delivered PA and/or dietary (DIET) intervention.

METHODS

Pilot randomized trial. 80 adults with previous stroke who are living at home with Internet access and able to exercise will be randomized in a 2 × 2 factorial (4-arm) pilot randomized, open-label, blinded outcome assessment trial to receive PA, DIET, PA + DIET, or control interventions via telehealth. The PA intervention aims to support participants to meet the minimum recommended levels of PA (150 min/week moderate exercise), and the DIET intervention aims to support participants to follow the AusMed (Mediterranean-style) diet. The control group receives usual care plus education about PA and healthy eating. The co-primary outcomes are feasibility (proportion and characteristics of eligible participants enrolled and proportion of scheduled intervention sessions attended) and safety (adverse events) at 6 months. The secondary outcomes include recurrent stroke risk factors (blood pressure, physical activity levels, and diet quality), fatigue, mood, and quality of life. Outcomes are measured at 3, 6, and 12 months.

CONCLUSION

This trial will produce evidence for the feasibility, safety, and potential effect of telehealth-delivered PA and DIET interventions for people with stroke. Results will inform development of an appropriately powered trial to test effectiveness to reduce major risk factors for recurrent stroke.

i-Rebound after Stroke-Eat for Health: Mediterranean Dietary Intervention Co-Design Using an Integrated Knowledge Translation Approach and the TIDieR Checklist

Lifestyle interventions to reduce second stroke risk are complex. For effective translation into practice, interventions must be specific to end-user needs and described in detail for replication. This study used an Integrated Knowledge Translation (IKT) approach and the Template for Intervention Description and Replication (TIDieR) checklist to co-design and describe a telehealth-delivered diet program for stroke survivors. Stroke survivors and carers (n = 6), specialist dietitians (n = 6) and an IKT research team (n = 8) participated in a 4-phase co-design process. Phase 1: the IKT team developed the research questions, and identified essential program elements and workshop strategies for effective co-design. Phase 2: Participant co-design workshops used persona and journey mapping to create user profiles to identify barriers and essential program elements. Phase 3: The IKT team mapped Phase 2 data to the TIDieR checklist and developed the intervention prototype. Phase 4: Co-design workshops were conducted to refine the prototype for trial. Rigorous IKT co-design fundamentally influenced intervention development. Modifications to the protocol based on participant input included ensuring that all resources were accessible to people with aphasia, an additional support framework and resources specific to outcome of stroke. The feasibility and safety of this intervention is currently being pilot tested (randomised controlled trial; 2019/ETH11533, ACTRN12620000189921).

Advancing Stroke Recovery Through Improved Articulation of Nonpharmacological Intervention Dose

Dose articulation is a universal issue of intervention development and testing. In stroke recovery, dose of a nonpharmaceutical intervention appears to influence outcome but is often poorly reported. The challenges of articulating dose in nonpharmacological stroke recovery research include: (1) the absence of specific internationally agreed dose reporting guidelines; (2) inadequate conceptualization of dose, which is multidimensional; and (3) unclear and inconsistent terminology that incorporates the multiple dose dimensions. To address these challenges, we need a well-conceptualized and consistent approach to dose articulation that can be applied across stroke recovery domains to stimulate critical thinking about dose during intervention development, as well as promote reporting of planned intervention dose versus actually delivered dose. We followed the Design Research Paradigm to develop a framework that guides how to articulate dose, conceptualizes the multidimensional nature and systemic linkages between dose dimensions, and provides reference terminology for the field. Our framework recognizes that dose is multidimensional and comprised of a duration of days that contain individual sessions and episodes that can be active (time on task) or inactive (time off task), and each individual episode can be made up of information about length, intensity, and difficulty. Clinical utility of this framework was demonstrated via hypothetical application to preclinical and clinical domains of stroke recovery. The suitability of the framework to address dose articulation challenges was confirmed with an international expert advisory group. This novel framework provides a pathway for better articulation of nonpharmacological dose that will enable transparent and accurate description, implementation, monitoring, and reporting, in stroke recovery research.

Early-phase dose articulation trials are underutilized for post-stroke motor recovery: A systematic scoping review

BACKGROUND

To enable development of effective interventions, there is a need to complete systematic early-phase dose articulation research. This scoping review aimed to synthesize dose articulation research of behavioral motor interventions for stroke recovery.

METHODS

MEDLINE and EMBASE were systematically searched for dose articulation studies. Preclinical experiments and adult clinical trials were classified based on the discovery pipeline and analyzed to determine which dose dimensions were articulated (time, scheduling or intensity) and how they were investigated (unidimensional vs multidimensional approach). Reporting of dose, safety and efficacy outcomes were summarized. The intervention description, risk of bias, and quality was appraised.

RESULTS

We included 41 studies: 3 of preclinical dose preparation (93 rodents), 2 Phase I dose ranging (21 participants), 9 Phase IIA dose screening (198 participants), and 27 Phase IIB dose finding (1879 participants). All studies adopted a unidimensional approach. Time was the most frequent dimension investigated (53%), followed by intensity (29%), and scheduling (18%). Overall, 95% studies reported an efficacy outcome; however, only 65% reported dose and 45% reported safety. Across studies, 61% were at high risk of bias, and the average percentage reporting of intervention description and quality was 61% and 67%, respectively.

CONCLUSION

This review highlights a need to undertake more high-quality, early-phase studies that systematically articulate intervention doses from a multidimensional perspective in the field of behavioral motor stroke recovery. To address this gap, we need to invest in adapting early phase trial designs, especially Phase I, to support multidimensional dose articulation.

Recommendations for Reporting on Rehabilitation Interventions

ABSTRACT

Clear reporting on rehabilitation treatments is critical for interpreting and replicating study results and for translating treatment research into clinical practice. This article reports the recommendations of a working group on improved reporting on rehabilitation treatments. These recommendations are intended to be combined with the efforts of other working groups, through a consensus process, to arrive at a reporting guideline for randomized controlled trials in physical medicine and rehabilitation (Randomized Controlled Trials Rehabilitation Checklist). The work group conducted a scoping review of 156 diverse guidelines for randomized controlled trial reporting, to identify themes that might be usefully applied to the field of rehabilitation. Themes were developed by identifying content that might improve or enhance existing items from the Template for Intervention Description and Replication. Guidelines addressing broad research domains tended to define reporting items generally, from the investigator's perspective of relevance, whereas those addressing more circumscribed domains provided more specific and operationalized items. Rehabilitation is a diverse field, but a clear description of the treatment's separable components, along with distinct treatment theories for each, can improve reporting of relevant information. Over time, expert consensus groups should develop more specific guideline extensions for circumscribed research domains, around coalescing bodies of treatment theory.

[Application of modern non-drug technologies to improve the quality of life of patients with hemiparesis]

In recent years, the improvement of the system of medical rehabilitation of patients with acute cerebrovascular accident has acquired special social significance due to the high morbidity.

OBJECTIVE

To study the effect of the combined use of a multifunctional platform and massage with a pulsed low-frequency electrostatic field on the motor functions of the lower limb, coordination and balance, as well as on the psychoemotional status and quality of life of patients after an ischemic stroke with hemiparesis in the late recovery period.

MATERIAL AND METHODS

The article presents data on the treatment of 120 patients who had an ischemic stroke with movement disorders in the form of hemiparesis with an increase in muscle tone by the type of spasticity in the late recovery period. All patients received standard drug therapy and underwent medical rehabilitation. The patients were divided into 3 groups: the main group - 40 patients who received massage with a pulsed low-frequency electrostatic field and training on a multifunctional platform with biofeedback (BFB) - COBS (mtd-Systems, Germany), a comparison group - 40 patients who received training on a multifunctional platform with biofeedback (BFB), control group - 40 patients.

RESULTS

In the initial state, all patients included in the study showed an uneven distribution of the load in the protocols «normal standing position» and «standing balance» with an advantage towards the healthy leg. After the course of treatment in the patients of the main group, all the evaluated indices were normalized, in the patients of the comparison group statistically significant less pronounced results were obtained, and in the patients of the control group only a positive trend was noted. When studying the quality of life and the effectiveness of treatment according to the EQ-5D questionnaire in the examined patients in the initial state, the indicator averaged 7.8±0.8 points. After the course of treatment, the patients of the main group showed a statistically significant decrease in the indicators of the EQ-5D questionnaire from 7.8±0.8 points in the initial state to 5.1±1.1 (p<0.001), which lasted up to 6 months. In patients of the comparison group in all periods of observation, a decrease in the indicator was also noted, but less pronounced, in patients in the control group, only a positive trend. The data were supported by the Hospital Anxiety and Depression Scale (HADS) score.

CONCLUSION

The use of complex rehabilitation with the inclusion of a multifunctional platform with biofeedback and electrostatic massage contributes to a pronounced improvement in the functional state of muscle tone, coordination and balance, a significant decrease in the level of anxiety and depression and has a pronounced positive effect on the quality of life and assessment of the health status of patients with hemiparesis in late recovery period after ischemic stroke.

Factors affecting the delivery of complex rehabilitation interventions in research with neurologically impaired adults: a systematic review

BACKGROUND

Rehabilitation research does not always improve patient outcomes because of difficulties implementing complex health interventions. Identifying barriers and facilitators to implementation fidelity is critical. Not reporting implementation issues wastes research resources and risks erroneously attributing effectiveness when interventions are not implemented as planned, particularly progressing from single to multicentre trials. The Consolidated Framework for Implementation Research (CFIR) and Conceptual Framework for Implementation Fidelity (CFIF) facilitate identification of barriers and facilitators. This review sought to identify barriers and facilitators (determinants) affecting implementation in trials of complex rehabilitation interventions for adults with long-term neurological conditions (LTNC) and describe implementation issues.

METHODS

Implementation, complex health interventions and LTNC search terms were developed. Studies of all designs were eligible. Searches involved 11 databases, trial registries and citations. After screening titles and abstracts, two reviewers independently shortlisted studies. A third resolved discrepancies. One reviewer extracted data in two stages; 1) descriptive study data, 2) units of text describing determinants. Data were synthesised by (1) mapping determinants to CFIF and CFIR and (2) thematic analysis.

RESULTS

Forty-three studies, from 7434 records, reported implementation determinants; 41 reported both barriers and facilitators. Most implied determinants but five used implementation theory to inform recording. More barriers than facilitators were mapped onto CFIF and CFIR constructs. "Patient needs and resources", "readiness for implementation", "knowledge and beliefs about the intervention", "facilitation strategies", "participant responsiveness" were the most frequently mapped constructs. Constructs relating to the quality of intervention delivery, organisational/contextual aspects and trial-related issues were rarely tapped. Thematic analysis revealed the most frequently reported determinants related to adherence, intervention perceptions and attrition.

CONCLUSIONS

This review has described the barriers and facilitators identified in studies implementing complex interventions for people with LTNCs. Early adoption of implementation frameworks by trialists can simplify identification and reporting of factors affecting delivery of new complex rehabilitation interventions. It is vital to learn from previous experiences to prevent unnecessary repetitions of implementation failure at both trial and service provision levels. Reported facilitators can provide strategies for overcoming implementation issues. Reporting gaps may be due to the lack of standardised reporting methods, researcher ignorance and historical reporting requirements.

Robot-assisted training compared with an enhanced upper limb therapy programme and with usual care for upper limb functional limitation after stroke: the RATULS three-group RCT

BACKGROUND

Loss of arm function is common after stroke. Robot-assisted training may improve arm outcomes.

OBJECTIVE

The objectives were to determine the clinical effectiveness and cost-effectiveness of robot-assisted training, compared with an enhanced upper limb therapy programme and with usual care.

DESIGN

This was a pragmatic, observer-blind, multicentre randomised controlled trial with embedded health economic and process evaluations.

SETTING

The trial was set in four NHS trial centres.

PARTICIPANTS

Patients with moderate or severe upper limb functional limitation, between 1 week and 5 years following first stroke, were recruited.

INTERVENTIONS

Robot-assisted training using the Massachusetts Institute of Technology-Manus robotic gym system (InMotion commercial version, Interactive Motion Technologies, Inc., Watertown, MA, USA), an enhanced upper limb therapy programme comprising repetitive functional task practice, and usual care.

MAIN OUTCOME MEASURES

The primary outcome was upper limb functional recovery 'success' (assessed using the Action Research Arm Test) at 3 months. Secondary outcomes at 3 and 6 months were the Action Research Arm Test results, upper limb impairment (measured using the Fugl-Meyer Assessment), activities of daily living (measured using the Barthel Activities of Daily Living Index), quality of life (measured using the Stroke Impact Scale), resource use costs and quality-adjusted life-years.

RESULTS

A total of 770 participants were randomised (robot-assisted training, n = 257; enhanced upper limb therapy, n = 259; usual care, n = 254). Upper limb functional recovery 'success' was achieved in the robot-assisted training [103/232 (44%)], enhanced upper limb therapy [118/234 (50%)] and usual care groups [85/203 (42%)]. These differences were not statistically significant; the adjusted odds ratios were as follows: robot-assisted training versus usual care, 1.2 (98.33% confidence interval 0.7 to 2.0); enhanced upper limb therapy versus usual care, 1.5 (98.33% confidence interval 0.9 to 2.5); and robot-assisted training versus enhanced upper limb therapy, 0.8 (98.33% confidence interval 0.5 to 1.3). The robot-assisted training group had less upper limb impairment (as measured by the Fugl-Meyer Assessment motor subscale) than the usual care group at 3 and 6 months. The enhanced upper limb therapy group had less upper limb impairment (as measured by the Fugl-Meyer Assessment motor subscale), better mobility (as measured by the Stroke Impact Scale mobility domain) and better performance in activities of daily living (as measured by the Stroke Impact Scale activities of daily living domain) than the usual care group, at 3 months. The robot-assisted training group performed less well in activities of daily living (as measured by the Stroke Impact Scale activities of daily living domain) than the enhanced upper limb therapy group at 3 months. No other differences were clinically important and statistically significant. Participants found the robot-assisted training and the enhanced upper limb therapy group programmes acceptable. Neither intervention, as provided in this trial, was cost-effective at current National Institute for Health and Care Excellence willingness-to-pay thresholds for a quality-adjusted life-year.

CONCLUSIONS

Robot-assisted training did not improve upper limb function compared with usual care. Although robot-assisted training improved upper limb impairment, this did not translate into improvements in other outcomes. Enhanced upper limb therapy resulted in potentially important improvements on upper limb impairment, in performance of activities of daily living, and in mobility. Neither intervention was cost-effective.

FUTURE WORK

Further research is needed to find ways to translate the improvements in upper limb impairment seen with robot-assisted training into improvements in upper limb function and activities of daily living. Innovations to make rehabilitation programmes more cost-effective are required.

LIMITATIONS

Pragmatic inclusion criteria led to the recruitment of some participants with little prospect of recovery. The attrition rate was higher in the usual care group than in the robot-assisted training or enhanced upper limb therapy groups, and differential attrition is a potential source of bias. Obtaining accurate information about the usual care that participants were receiving was a challenge.

Biopsychosocial intervention for stroke carers (BISC): results of a feasibility randomised controlled trial and nested qualitative interview study

OBJECTIVE

To determine the feasibility of recruiting to and delivering a biopsychosocial intervention for carers of stroke survivors.

DESIGN

Feasibility randomised controlled study with nested qualitative interview study.

SETTING

The intervention was delivered in the community in either a group or one-to-one format.

SUBJECTS

Carers and stroke survivors within one year of stroke onset.

INTERVENTIONS

A carer targeted intervention delivered by a research psychologist in six structured two-hour sessions or usual care control. The intervention combined education about the biological, psychological and social effects of stroke with strategies and techniques focussing on adjustment to stroke and caregiving. Stroke survivors in both groups received baseline and follow-up assessment but no intervention.

MAIN OUTCOME

Recruitment rate, study attrition, fidelity of intervention delivery, acceptability and sensitivity of outcome measures used (health related quality of life, anxiety and depression and carer burden six months after randomisation).

RESULTS

Of the 257 carers approached, 41 consented. Six withdrew before randomisation. Eighteen participants were randomised to receive the intervention and 17 to usual care. Attendance at sessions was greater when treated one-to-one. Feedback interviews suggested that participants found the intervention acceptable and peer support particularly helpful in normalising their feelings. Thirty participants were assessed at follow-up with improvements from baseline on all health measures for both groups.

CONCLUSIONS

Our results suggest that a biopsychosocial intervention was acceptable to carers and can be delivered in group and one-to-one formats. Timing of approach and mode of intervention delivery is critical and requires tailoring to the carers individual needs.

Exploring the factors influencing the use of electrically assisted bikes (e-bikes) by stroke survivors: a mixed methods multiple case study

PURPOSE

E-bikes have the potential to overcome some of the barriers that stroke survivors face with regards to physical activity. This study aims to explore the factors that affect e-bike usage by stroke survivors.

METHODS

A mixed methods multiple case studies design, using semi-structured interviews and GPS data. Subject to GP approval, participants loaned an e-bike or e-trike for up to three months. Interviews were undertaken pre and post intervention. The COM-B behaviour change model acted as a framework for analysis. GPS data relating to journey duration and distance travelled was collected fortnightly.

RESULTS

Six participants were recruited; only three loaned an e-bike/e-trike (with adaptations as required). Storage, being unable to get GP approval, and safety were withdrawal reasons. Level of impairment was a factor influencing the type of e-bike used, level of support required and the motivation of the participants.

CONCLUSION

Stroke survivors can use e-bikes although barriers exist. Electrical assistance was a positive factor in enabling some of the participants to cycle outdoors. Due to the small sample size and the number of participants who were able to loan an e-bike, further research is required to determine whether e-bikes are a feasible and effective intervention to increase physical activity for stroke survivors.IMPLICATIONS FOR REHABILITATIONThe assistance provided by the e-bike/e-trike could provide stroke survivors the opportunity to cycle outdoors.E-bikes/e-trikes could facilitate participation of activities of everyday living such as shopping, hobbies and increase levels of physical activity.Rehabilitation could focus on physical impairment, its effects on self-confidence, and knowledge surrounding the e-bike to overcome barriers to cycling.Social support, the belief that e-bike was an enjoyable mode of physical activity that was good for their health were reported by the participants as important factors for using the e-bike/e-trike.

Evaluation of the enhanced upper limb therapy programme within the Robot-Assisted Training for the Upper Limb after Stroke trial: descriptive analysis of intervention fidelity, goal selection and goal achievement

Objective:

To report the fidelity of the enhanced upper limb therapy programme within the Robot-Assisted Training for the Upper Limb after stroke (RATULS) randomized controlled trial, the types of goals selected and the proportion of goals achieved.

Design:

Descriptive analysis of data on fidelity, goal selection and achievement from an intervention group within a randomized controlled trial.

Setting:

Out-patient stroke rehabilitation within four UK NHS centres.

Subjects:

259 participants with moderate-severe upper limb activity limitation (Action Research Arm Test 0–39) between one week and five years post first stroke.

Intervention:

The enhanced upper limb therapy programme aimed to provide 36 one-hour sessions, including 45 minutes of face-to-face therapy focusing on personal goals, over 12 weeks.

Results:

7877/9324 (84%) sessions were attended; a median of 34 [IQR 29–36] per participant. A median of 127 [IQR 70–190] repetitions were achieved per participant per session attended. Based upon the Canadian Occupational Performance Measure, goal categories were: self-care 1449/2664 (54%); productivity 374/2664 (14%); leisure 180/2664 (7%) and ‘other’ 661/2664 (25%). For the 2051/2664 goals for which data were available, 1287 (51%) were achieved, ranging between 27% by participants more than 12 months post stroke with baseline Action Research Arm Test scores 0–7, and 88% by those less than three months after stroke with scores 8–19.

Conclusions:

Intervention fidelity was high. Goals relating to self-care were most commonly selected. The proportion of goals achieved varied, depending on time post stroke and baseline arm activity limitation.

Facilitators and "deal breakers": a mixed methods study investigating implementation of the Goal setting and action planning (G-AP) framework in community rehabilitation teams

BACKGROUND

High quality goal setting in stroke rehabilitation is vital, but challenging to deliver. The G-AP framework (including staff training and a stroke survivor held G-AP record) guides patient centred goal setting with stroke survivors in community rehabilitation teams. We found G-AP was acceptable, feasible to deliver and clinically useful in one team. The aim of this study was to conduct a mixed methods investigation of G-AP implementation in diverse community teams prior to a large-scale evaluation.

METHODS

We approached Scottish community rehabilitation teams to take part. Following training, G-AP was delivered to stroke survivors within participating teams for 6 months. We investigated staff experiences of G-AP training and its implementation using focus groups and a training questionnaire. We investigated fidelity of G-AP delivery through case note review. Focus group data were analysed using a Framework approach; identified themes were mapped into Normalisation Process Theory constructs. Questionnaire and case note data were analysed descriptively.

RESULTS

We recruited three teams comprising 55 rehabilitation staff. Almost all staff (93%, 51/55) participated in G-AP training; of those, 80% (n = 41/51) completed the training questionnaire. Training was rated as 'good' or 'very good' by almost all staff (92%, n = 37/41). G-AP was broadly implemented as intended in two teams. Implementation facilitators included - G-AP 'made sense'; repetitive use of G-AP in practice; flexible G-AP delivery and positive staff appraisals of G-AP impact. G-AP failed to gain traction in the third team. Implementation barriers included - delays between G-AP training and implementation; limited leadership engagement; a poor 'fit' between G-AP and the team organisational structure and simultaneous delivery of other goal setting methods. Staff recommended (i) development of training to include implementation planning; (ii) ongoing local implementation review and tailoring, and (iii) development of electronic and aphasia friendly G-AP records.

CONCLUSIONS

The interaction between G-AP and the practice setting is critical to implementation success or failure. Whilst facilitators support implementation success, barriers can collectively act as implementation "deal breakers". Local G-AP implementation efforts should be planned, monitored and tailored. These insights can inform implementation of other complex interventions in community rehabilitation settings.

A co-production approach guided by the behaviour change wheel to develop an intervention for reducing sedentary behaviour after stroke

Background

Stroke survivors are highly sedentary; thus, breaking up long uninterrupted bouts of sedentary behaviour could have substantial health benefit. However, there are no intervention strategies specifically aimed at reducing sedentary behaviour tailored for stroke survivors. The purpose of this study was to use co-production approaches to develop an intervention to reduce sedentary behaviour after stroke.

Methods

A series of five co-production workshops with stroke survivors, their caregivers, stroke service staff, exercise professionals, and researchers were conducted in parallel in two-stroke services (England and Scotland). Workshop format was informed by the behaviour change wheel (BCW) framework for developing interventions and incorporated systematic review and empirical evidence. Taking an iterative approach, data from activities and audio recordings were analysed following each workshop and findings used to inform subsequent workshops, to inform both the activities of the next workshop and ongoing intervention development.

Findings

Co-production workshop participants (n = 43) included 17 staff, 14 stroke survivors, six caregivers and six researchers. The target behaviour for stroke survivors is to increase standing and moving, and the target behaviour for caregivers and staff is to support and encourage stroke survivors to increase standing and moving. The developed intervention is primarily based on co-produced solutions to barriers to achieving the target behaviour. The developed intervention includes 34 behaviour change techniques. The intervention is to be delivered through stroke services, commencing in the inpatient setting and following through discharge into the community. Participants reported that taking part in intervention development was a positive experience.

Conclusions

To our knowledge, this is the first study that has combined the use of co-production and the BCW to develop an intervention for use in stroke care. In-depth reporting of how a co-production approach was combined with the BCW framework, including the design of bespoke materials for workshop activities, should prove useful to other researchers and practitioners involved in intervention development in stroke.

Early mobilisation post-stroke: a systematic review and meta-analysis of individual participant data

PURPOSE

To investigate the safety and efficacy of early mobilisation (EM) compared to usual care by meta-analysing individual participant data (IPD).

MATERIALS AND METHODS

IPD were sought from randomised controlled trials comparing out-of-bed mobilisation starting within 48 h from stroke onset to usual care for acute stroke patients. Six trials were sourced from a recent Cochrane review. Favourable outcome (modified Rankin Scale 0-2) and death at 3 months post-stroke were compared between both groups using mixed-effect logistic regression modelling. Adjusted odds ratios (aORs) with respective 95% confidence intervals (95%CI) were reported.

RESULTS

Out of 2630 participants, 1437 (54.6%) were assigned to EM and 1193 (45.4%) to usual care. Intervention protocols varied considerably between trials. The median (interquartile range) delay to starting mobilisation post-stroke onset was 20 h (14.5-23.8) for EM and 23 h (16.7-34.3) for usual care group. Fewer EM participants had a favourable outcome at 3 months post-stroke compared to the usual care group (678 [48%] vs. 611 [52%]; aOR = 0.75, 95%CI: 0.62-0.92, p = 0.005). No difference in death at 3 months post-stroke between EM and usual care was observed (102 [7%] vs. 84 [7%]; aOR = 1.46, 95%CI: 0.92-2.31, p = 0.108).

CONCLUSION

The commencement of mobilisation should only be considered after 24 h post-stroke. Further research is required to identify safe, optimal dose, and timing of EM post-stroke.IMPLICATIONS FOR REHABILITATIONPatients who commenced mobilisation early after stroke had worse outcome than usual care.Insufficient detail about mobilisation interventions or usual care in many studies limits any further interpretation.The commencement of mobilisation should only be considered after 24-h post-stroke.

Treatment dose in post-stroke aphasia: A systematic scoping review

Little is known about how the amount of treatment a person with aphasia receives impacts aphasia recovery following stroke, yet this information is vital to ensure effective treatments are delivered efficiently. Furthermore, there is no standard dose terminology in the stroke rehabilitation or aphasia literature. This scoping review aims to systematically map the evidence regarding dose in treatments for post-stroke aphasia and to explore how treatment dose is conceptualized, measured and reported in the literature. A comprehensive search was undertaken in June 2019. One hundred and twelve intervention studies were reviewed. Treatment dose (amount of treatment) has been conceptualized as both a measure of time and a count of discrete therapeutic elements. Doses ranged from one to 100 hours, while some studies reported session doses of up to 420 therapeutic inputs per session. Studies employ a wide variety of treatment schedules (i.e., session dose, session frequency, and intervention duration) and the interaction of dose parameters may impact the dose-response relationship. High dose interventions delivered over short periods may improve treatment efficiency while maintaining efficacy. Person- and treatment-level factors that mediate tolerance of high dose interventions require further investigation. Systematic exploration of dose-response relationships in post-stroke aphasia treatment is required.

UK consensus on pre-clinical vascular cognitive impairment functional outcomes assessment: Questionnaire and workshop proceedings

Assessment of outcome in preclinical studies of vascular cognitive impairment (VCI) is heterogenous. Through an ARUK Scottish Network supported questionnaire and workshop (mostly UK-based researchers), we aimed to determine underlying variability and what could be implemented to overcome identified challenges. Twelve UK VCI research centres were identified and invited to complete a questionnaire and attend a one-day workshop. Questionnaire responses demonstrated agreement that outcome assessments in VCI preclinical research vary by group and even those common across groups, may be performed differently. From the workshop, six themes were discussed: issues with preclinical models, reasons for choosing functional assessments, issues in interpretation of functional assessments, describing and reporting functional outcome assessments, sharing resources and expertise, and standardization of outcomes. Eight consensus points emerged demonstrating broadly that the chosen assessment should reflect the deficit being measured, and therefore that one assessment does not suit all models; guidance/standardisation on recording VCI outcome reporting is needed and that uniformity would be aided by a platform to share expertise, material, protocols and procedures thus reducing heterogeneity and so increasing potential for collaboration, comparison and replication. As a result of the workshop, UK wide consensus statements were agreed and future priorities for preclinical research identified.

Factors influencing sedentary behaviours after stroke: findings from qualitative observations and interviews with stroke survivors and their caregivers

BACKGROUND

Stroke survivors are more sedentary than healthy, age-matched controls, independent of functional capacity. Interventions are needed to encourage a reduction in overall sedentary time, and regular breaks in prolonged periods of sedentary behaviour. This study captured the views and experiences of stroke survivors and their caregivers related to sedentary behaviour after stroke, to inform the development of an intervention to reduce sedentary behaviour.

METHODS

Mixed-methods qualitative study. Non-participant observations were completed in two stroke services, inclusive of inpatient and community settings in the United Kingdom. Semi-structured interviews were conducted with stroke survivors and their caregivers (if available) at six- or nine-months post-stroke. Underpinned by the capability, opportunity and motivation (COM-B) model of behaviour change, observational data (132 h) were analysed thematically and interview data (n = 31 stroke survivors, n = 12 caregivers) were analysed using the Framework approach.

RESULTS

Observation participants differed in functional ability whereas stroke survivor interviewees were all ambulant. Six themes related to sedentary behaviour after stroke were generated: (1) sedentary behaviour levels and patterns after stroke; (2) the physical and social environment in the stroke service and in the home; (3) standing and movement capability after stroke; (4) emotion and motivation after stroke; (5) caregivers' influence on, and role in influencing stroke survivors' sedentary behaviour; and (6) intervening to reduce sedentary behaviour after stroke. Capability, opportunity and motivation were influenced by the impact of the stroke and caregivers' inclination to support sedentary behaviour reduction. Stroke survivors reported being more sedentary than they were pre-stroke due to impaired balance and co-ordination, increased fatigue, and reduced confidence in mobilising. Caregivers inclination to support stroke survivors to reduce sedentary behaviour depended on factors including their willingness to withdraw from the caregiver role, and their perception of whether the stroke survivor would act on their encouragement.

CONCLUSIONS

Many stroke survivors indicate being open to reducing sedentary behaviour, with appropriate support from stroke service staff and caregivers. The findings from this study have contributed to an intervention development process using the Behaviour Change Wheel (BCW) approach to develop strategies to reduce sedentary behaviour after stroke.

An exploration of aphasia therapy dosage in the first six months of stroke recovery

Aphasia research uses the length of time within rehabilitation sessions as the main measure of dosage. Few papers detail therapeutic ingredients or outline the number of times these were delivered over the treatment period. The present observational study identified therapeutic ingredients in the Very Early Rehabiltiation in SpEech (VERSE) trial and explored the dosage provided using a model of cumulative intervention intensity (CII). Therapists video recorded one therapy session per week and 53 (12%) randomly selected therapy videos were analysed. The videos were coded for number of error productions, self-corrections and type and frequency of therapist cueing. The Western Aphasia Battery Revised-Aphasia Quotient (WABR-AQ) was used for measuring patient outcome with total verbal utterances (p < 0.001) and cues used with success (p < 0.001) being independent positive predictors of WABR-AQ score at six months post stroke and hypothesized as key therapeutic ingredients. The CII was calculated by counting identified therapeutic ingredients and multiplying this by the number of sessions completed. Collectively, the key ingredients occurred on average 504 times per session and over 10,000 times per participant during the treatment period. This paper reports a novel approach for identifying key treatment ingredients and detailing the dosage delivered within an early aphasia rehabilitation trial.

The effectiveness of extracorporeal shock wave therapy for improving upper limb spasticity and functionality in stroke patients: a systematic review and meta-analysis

OBJECTIVE

To assess the effectiveness of Extracorporeal Shock Wave Therapy for reducing spasticity and improving functionality of the upper limb in stroke survivors.

DATA SOURCES

A systematic review of MEDLINE, Cochrane Central Register of Controlled Trials, CINAHL, PEDro, REHABDATA, Scielo, Scopus, Web of Science, Tripdatabase and Epistemonikos from 1980 to April 2020 was carried out.

REVIEW METHODS

The bibliography was screened to identify randomized controlled clinical trials that applied extracorporeal shock waves to upper limb spastic muscles in post-stroke individuals. Two reviewers independently screened references, selected relevant studies, extracted data and assessed risk of bias using the PEDro scale. The primary outcome was spasticity and functionality of the upper limb.

RESULTS

A total of 1,103 studies were identified and 16 randomized controlled trials were finally included (764 individuals) were analyzed. A meta-analysis was performed and a beneficial effect on spasticity was found. The mean difference (MD) on the Modified Ashworth Scale for comparison extracorporeal shock wave versus sham was -0.28; with a 95% confidence interval (CI) from -0.54 to -0.03. The MD of the comparison of extracorporeal shock wave plus conventional physiotherapy versus conventional physiotherapy was -1.78; 95% CI from -2.02 to -1.53. The MD for upper limb motor-function using the Fugl Meyer Assessment was 0.94; 95% CI from 0.42 to 1.47 in the short term and 0.97; 95% CI from 0.19 to 1.74 in the medium term.

CONCLUSION

The extracorporeal shock wave therapy is effective for reducing upper limb spasticity. Adding it to conventional therapy provides an additional benefit.

Intracerebral implantation of human neural stem cells and motor recovery after stroke: multicentre prospective single-arm study (PISCES-2)

BACKGROUND

Human neural stem cell implantation may offer improved recovery from stroke. We investigated the feasibility of intracerebral implantation of the allogeneic human neural stem cell line CTX0E03 in the subacute-chronic recovery phase of stroke and potential measures of therapeutic response in a multicentre study.

METHODS

We undertook a prospective, multicentre, single-arm, open-label study in adults aged >40 years with significant upper limb motor deficits 2-13 months after ischaemic stroke. 20 million cells were implanted by stereotaxic injection to the putamen ipsilateral to the cerebral infarct. The primary outcome was improvement by 2 or more points on the Action Research Arm Test (ARAT) subtest 2 at 3 months after implantation.

FINDINGS

Twenty-three patients underwent cell implantation at eight UK hospitals a median of 7 months after stroke. One of 23 participants improved by the prespecified ARAT subtest level at 3 months, and three participants at 6 and 12 months. Improvement in ARAT was seen only in those with residual upper limb movement at baseline. Transient procedural adverse effects were seen, but no cell-related adverse events occurred up to 12 months of follow-up. Two deaths were unrelated to trial procedures.

INTERPRETATION

Administration of human neural stem cells by intracerebral implantation is feasible in a multicentre study. Improvements in upper limb function occurred at 3, 6 and 12 months, but not in those with absent upper limb movement at baseline, suggesting a possible target population for future controlled trials.
