Overcoming practical challenges to conducting clinical research in the inpatient stroke rehabilitation setting

Therapies and Challenges in the Post-Stroke Aphasia Rehabilitation Arena: Current and Future Prospects

Aphasia is a serious consequence of stroke that results in a breakdown in communication. The course of aphasia recovery differs between afflicted individuals, and responsiveness to treatment cannot be predicted. Aphasiologists continue to investigate numerous behavioral treatment protocols that have shifted their focus to complimentary rehabilitation strategies. The aim of this study is threefold. First, to summarize the different categories of aphasia interventions post-stroke, considering their respective protocols, and present available evidence on the effectiveness of those protocols. Second, to document the challenges regarding the prediction of aphasia treatment response post-stroke in individual patients. Third, to report the challenges faced by researchers in recruiting people with aphasia (PWA) for treatment studies, and provide recommendations on how to increase participant recruitment and retention. This study provides up-to-date information on (i) effective therapies and aphasia recovery processes, and (ii) research recruitment hurdles together with potential strategies for overcoming them.

Functional standing frame programme early after severe sub-acute stroke (SPIRES): a randomised controlled feasibility trial

BACKGROUND

Early mobilisation (> 24 h post-stroke) is recommended for people with stroke. However, there is a paucity of evidence about how to implement early mobilisation for people who have had a severe stroke. Prolonged standing and task-specific training (sit-to-stand repetitions) have separately been evaluated in the literature; however, these functionally linked tasks have not been evaluated in combination for people with severe sub-acute stroke.

METHODS

The objective was to determine the feasibility of conducting a randomised controlled trial (RCT) of a functional standing frame programme compared with usual physiotherapy for people with severe sub-acute stroke. An assessor-blinded feasibility RCT with nested qualitative component (interviews and focus group) and process evaluation was adopted. Participants were aged ≥ 18 years with new diagnosis of severe sub-acute stroke (modified Rankin Scale (mRS) 4/5) from four Stroke Rehabilitation Units across South West England. Participants were randomised to receive either: (1) functional standing frame programme (30 min. standing plus sit-to-stand repetitions) plus 15 min of usual physiotherapy daily (intervention); (2) usual physiotherapy (45 min) daily (control). Both programmes were protocolised to be undertaken a minimum of five sessions per week for 3 weeks. Feasibility indicators included process, resource, management, and safety. Adherence, fidelity, and acceptability of the trial and intervention were evaluated using data recorded by therapists, observation of intervention and control sessions, interviews and one focus group. Patient measures of motor impairment, activities/participation, and quality of life were carried out by blinded assessors at baseline, 3, 15, 29, and 55 weeks post-randomisation.

RESULTS

Forty-five participants (51-96 years; 42% male, mRS 4 = 80% 5 = 20%) were randomised (n = 22 to intervention). Twenty-seven (60%) participants were followed-up at all time points. Twelve participants (27%) died during the trial; no deaths were related to the trial. Adherence to the minimum number of sessions was low: none of the participants completed all 21 sessions, and only 8 participants (18%) across both groups completed ≥ 15 sessions, over the 3 weeks; 39% intervention; 51% control sessions were completed; mean session duration 39 min (SD 19) control, 37 min intervention (SD 11). Intervention group: mean standing time 13 min (SD 9); mean sit-to-stand repetitions/session 5 (SD 4). Interviews were conducted with 10 participants, four relatives and six physiotherapists. Five physiotherapists attended a focus group.

CONCLUSIONS

The majority of progression criteria for this feasibility trial were met. However, adherence to the interventions was unacceptably low. This aspect of the trial design needs to be addressed prior to moving to a definitive RCT of this standing frame intervention in people with severe sub-acute stroke. Solutions have been identified to address these concerns.

Practitioner Engagement by Academic Researchers: A Scoping Review of Nursing, Midwifery, and Therapy Professions Literature

BACKGROUND

Engagement of frontline practitioners by academic researchers in the research process is believed to afford benefits toward closing the research practice gap. However, little is known about if and how academic researchers engage nurses, midwives, or therapists in research activities or if evidence supports these claims of positive impact.

METHOD

A scoping review was undertaken using the Arksey and O'Malley (2005) framework to identify the extent to which this phenomenon has been considered in the literature.

RESULTS

An iterative search carried out in CINAHL, Pubmed, Medline, and Embase retrieved 32 relevant papers published 2000 to 2017, with the majority from the last 2-years. Retained papers described or evaluated active engagement of a practitioner from nursing, midwifery, and therapy disciplines in at least one stage of a research project other than as a study participant. Engagement most often took place in one research activity with few examples of engagement throughout the research process. Limited use of theory and variations in terms used to describe practitioner engagement by researchers was observed. Subjective perspectives of practitioners' experiences and a focus on challenges and benefits were the most prominently reported outcomes. Few attempts were found to establish effects which could support claims that practitioner engagement can enhance the use of findings or impact health outcomes.

CONCLUSION

It is recommended that a culture of practitioner engagement is cultivated by developing guiding theory, establishing consistent terminology, and building an evidence base through empirical evaluations which provide objective data to support claims that this activity can positively influence the research practice gap.

Researcher practitioner engagement in health research: The development of a new concept

The engagement of frontline practitioners in the production of research-derived knowledge is often advocated. Doing so can address perceived gaps between what is known from research and what happens in clinical practice. Engagement practices span a continuum, from co-production approaches underpinned by principles of equality and power sharing to those which can minimalize practitioners' contributions to the knowledge production process. We observed a conceptual gap in published healthcare literature that labels or defines practitioners' meaningful contribution to the research process. We, therefore, aimed to develop the concept of "Researcher Practitioner Engagement" in the context of academically initiated healthcare research in the professions of nursing, midwifery, occupational therapy, physiotherapy, and speech and language therapy. Guided by Schwartz-Barcott et al.'s hybrid model of concept development, published examples were analyzed to establish the attributes, antecedents, and consequences of this type of engagement. Academic researchers (n = 17) and frontline practitioners (n = 8) with relevant experience took part in online focus groups to confirm, eliminate, or elaborate on these proposed concept components. Combined analysis of theoretical and focus group data showed that the essence of this form of engagement is that practitioners' clinical knowledge is valued from a study's formative stages. The practitioner's clinical perspectives inform problem-solving and decision-making in study activities and enhance the professional and practice relevance of a study. The conceptual model produced from the study findings forms a basis to guide engagement practices, future concept testing, and empirical evaluation of engagement practices.

Publication Rate and Consistency of Registered Trials of Motor-Based Stroke Rehabilitation

OBJECTIVE

To determine the publication rate of motor-rehabilitation trials poststroke and the consistency between registry records and their corresponding main publications in trial design, primary objectives and outcomes, eligibility criteria, and sample size.

METHODS

We searched 18 clinical trial registries to identify randomized controlled trials of motor-based stroke rehabilitation registered after July 2005 and completed before April 2017. Eligible trials included adults with stroke, with at least one outcome measure related to motor function. Information in the registry records was compared with that of their main publications, if any.

RESULTS

Three hundred twenty-three trials met our eligibility criteria; we were unable to find a peer-reviewed publication reporting the main findings for 46% (150/323) of these. Of the 169 trials with peer-reviewed articles published in English, 141 (83%) were consistent with the registry record in trial design, 100 (59%) were consistent in primary objectives, 71 (42%) were consistent in primary outcomes, 28 (17%) were consistent in eligibility criteria, and 74 (44%) were consistent in sample size.

CONCLUSIONS

Approximately half of motor-based stroke rehabilitation trials were not published, even more than 3 years after the end of the trial. When main publications were found, they substantially deviated from information in the registry record. These findings highlight the importance of trial registries for identifying unpublished stroke rehabilitation trials and of searching trial registries when conducting systematic reviews and meta-analysis to help ensure that reviews are unbiased.

Three short sessions of physiotherapy during rehabilitation after hip fracture were no more effective in improving mobility than a single longer session: a randomised controlled trial

OBJECTIVES

To determine if three short daily sessions of physiotherapy for rehabilitation inpatients after hip fracture is more effective than providing one long daily session in improving mobility.

DESIGN

A single-blinded randomised controlled trial.

SETTING

Two inpatient rehabilitation wards at a hospital in Melbourne, Australia.

PARTICIPANTS

Seventy-six rehabilitation inpatients after hip fracture. The key exclusion criterion was not being allowed to weight bear.

INTERVENTIONS

All participants received multidisciplinary rehabilitation. Experimental participants received three 15-minute sessions of physiotherapy 5 days per week until discharge. Control participants received one 45-minute session of physiotherapy 5 days per week until discharge.

MAIN OUTCOME MEASURES

The primary outcome, mobility, was assessed with the de Morton Mobility Index 2 weeks after admission and at discharge. Secondary outcomes were Functional Independence Measure mobility (transfers, ambulation, steps), physical activity measured with an accelerometer, length of stay, discharge destination, readmissions within 30 days of discharge, and patient and physiotherapist satisfaction.

RESULTS

Sixty-seven (88%) participants completed mobility assessment at discharge and 34 (45%) at 2 weeks. There were a greater proportion of missed sessions in the experimental group (84% adherence vs 95%). There was no between-group difference in mobility at discharge (MD -1.9 points, 95%CI-6.9 to 3.2) or at 2 weeks (MD -3.5 points, 95%CI-15.4 to 8.4). There were no between-group differences in any secondary outcomes.

CONCLUSIONS

Providing inpatient physiotherapy rehabilitation in three shorter sessions resulted in more missed sessions and likely did not improve mobility outcomes compared with providing one longer session for patients recovering from hip fracture.

Using Vision to Study Poststroke Recovery and Test Hypotheses About Neurorehabilitation

Approximately one-third of stroke patients suffer visual field impairment as a result of their strokes. However, studies using the visual pathway as a paradigm for studying poststroke recovery are limited. In this article, we propose that the visual pathway has many features that make it an excellent model system for studying poststroke neuroplasticity and assessing the efficacy of therapeutic interventions. First, the functional anatomy of the visual pathway is well characterized, which makes it well suited for functional neuroimaging studies of poststroke recovery. Second, there are multiple highly standardized and clinically available diagnostic tools and outcome measures that can be used to assess visual function in stroke patients. Finally, as a sensory modality, the assessment of vision is arguably less likely to be affected by confounding factors such as functional compensation and patient motivation. Given these advantages, and the general similarities between poststroke visual field recovery and recovery in other functional domains, future neurorehabilitation studies should consider using the visual pathway to better understand the physiology of neurorecovery and test potential therapeutics.

Feasibility and clinical experience of implementing a myoelectric upper limb orthosis in the rehabilitation of chronic stroke patients: A clinical case series report

Individuals with stroke are often left with persistent upper limb dysfunction, even after treatment with traditional rehabilitation methods. The purpose of this retrospective study is to demonstrate feasibility of the implementation of an upper limb myoelectric orthosis for the treatment of persistent moderate upper limb impairment following stroke (>6 months). Methods: Nine patients (>6 months post stroke) participated in treatment at an outpatient Occupational Therapy department utilizing the MyoPro myoelectric orthotic device. Group therapy was provided at a frequency of 1–2 sessions per week (60–90 minutes per session). Patients were instructed to perform training with the device at home on non-therapy days and to continue with use of the device after completion of the group training period. Outcome measures included Fugl-Meyer Upper Limb Assessment (FM) and modified Ashworth Scale (MAS). Results: Patients demonstrated clinically important and statistically significant improvement of 9.0±4.8 points (p = 0.0005) on a measure of motor control impairment (FM) during participation in group training. It was feasible to administer the training in a group setting with the MyoPro, using a 1:4 ratio (therapist to patients). Muscle tone improved for muscles with MAS >1.5 at baseline. Discussion: Myoelectric orthosis use is feasible in a group clinic setting and in home-use structure for chronic stroke survivors. Clinically important motor control gains were observed on FM in 7 of 9 patients who participated in training.

Methodological issues in the design and evaluation of supported communication for aphasia training: a cluster-controlled feasibility study

OBJECTIVE

To assess the feasibility and acceptability of training stroke service staff to provide supported communication for people with moderate-severe aphasia in the acute phase; assess the suitability of outcome measures; collect data to inform sample size and Health Economic evaluation in a definitive trial.

DESIGN

Phase II cluster-controlled, observer-blinded feasibility study.

SETTINGS

In-patient stroke rehabilitation units in the UK matched for bed numbers and staffing were assigned to control and intervention conditions.

PARTICIPANTS

70 stroke rehabilitation staff from all professional groups, excluding doctors, were recruited. 20 patients with moderate-severe aphasia were recruited.

INTERVENTION

Supported communication for aphasia training, adapted to the stroke unit context versus usual care. Training was supplemented by a staff learning log, refresher sessions and provision of communication resources.

MAIN OUTCOME MEASURES

Feasibility of recruitment and acceptability of the intervention and of measures required to assess outcomes and Health Economic evaluation in a definitive trial. Staff outcomes: Measure of Support in Conversation; patient outcomes: Stroke and Aphasia Quality of Life Scale; Communicative Access Measure for Stroke; Therapy Outcome Measures for aphasia; EQ-5D-3L was used to assess health outcomes.

RESULTS

Feasibility of staff recruitment was demonstrated. Training in the intervention was carried out with 28 staff and was found to be acceptable in qualitative reports. 20 patients consented to take part, 6 withdrew. 18 underwent all measures at baseline; 16 at discharge; and 14 at 6-month follow-up. Of 175 patients screened 71% were deemed to be ineligible, either lacking capacity or too unwell to participate. Poor completion rates impacted on assessment of patient outcomes. We were able to collect sufficient data at baseline, discharge and follow-up for economic evaluation.

CONCLUSIONS

The feasibility study informed components of the intervention and implementation in day-to-day practice. Modifications to the design are needed before a definitive cluster-randomised trial can be undertaken.
