What speech and language therapy do community dwelling stroke survivors with aphasia receive in the UK?

European Stroke Organisation (ESO) guideline on aphasia rehabilitation

Evidence of effective aphasia rehabilitation is emerging, yet intervention and delivery varies widely. This European Stroke Organisation guideline adhered to the guideline development standard procedures and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. The resulting multi-disciplinary, evidence-based recommendations support the delivery of high-quality stroke-related aphasia rehabilitation. The working group identified 10 clinically relevant aphasia rehabilitation questions and rated outcomes' relevance and importance. Following systematic searching, independent reviewers screened title-abstracts and full-texts for randomised controlled trials of speech-language therapy (SLT) for stroke-related aphasia. Results were profiled using PRISMA. Risk-of-bias was evaluated using the Cochrane Risk-of-Bias 1 tool. We prioritised final-value data. Where possible we conducted meta-analyses (RevMan) using random effects and mean, standardised mean differences (functional communication, quality of life, aphasia severity, auditory comprehension and spoken language outcomes) or odds ratios (adverse events). Using GRADE, we judged quality of the evidence (high-to-very low) and ESO recommendation strength (very strong-to-very weak). Where evidence was insufficient to support recommendations, expert opinions were described. Based on low-quality evidence we recommend the provision of higher total SLT dose (⩾20 h) and suggest higher SLT intensity and frequency to improve outcomes in aphasia rehabilitation. Similarly, we suggest the provision of individually-tailored SLT and digital and group therapy delivery models. Very low-level evidence for transcranial direct current stimulation (tDCS) with SLT informed the expert consensus that such interventions should only be provided in the context of high-quality trials. Evidence-based clinical-research priorities to inform SLT aphasia rehabilitation intervention choice and delivery are highlighted.

Success rates of intensive aphasia therapy: real-world data from 448 patients between 2003 and 2020

BACKGROUND

Aphasia is a devastating consequence after stroke, affecting millions of patients each year. Studies have shown that intensive speech and language therapy (SLT) is effective in the chronic phase of aphasia. Leveraging a large single-center cohort of persons with aphasia (PWA) including patients also in the subacute phase, we assessed treatment effects of intensive aphasia therapy in a real-world setting.

METHODS

Data were collected at the Aachen aphasia ward in Germany between 2003 and 2020. Immediate treatment responses across different language domains were assessed with the Aachen Aphasia Test (AAT) using single-case psychometrics, conducted before and after 6-7 weeks of intensive SLT (10 h per week, median (IQR) dosage = 68 (61-76)). We adjusted for spontaneous recovery in subacute patients. Differential treatment effects between subgroups of chronicity and predictors of therapy response were investigated.

RESULTS

A total of 448 PWA were included (29% female, median (IQR) age = 54 (46-62) years, median (IQR) time post-onset = 11 (6-20) months) with 12% in the early subacute, 15% in the late subacute and 74% in the chronic phase of aphasia. The immediate responder rate was 59%. Significant improvements in all AAT subtests und subscales were observed hinting at broad effectiveness across language domains. The degree of therapy-induced improvement did not differ between the chronicity groups. Time post-onset, dosage of therapy and aphasia severity at the beginning of treatment were predictors of immediate treatment response.

DISCUSSION

Intensive therapy protocols for aphasia after stroke are yielding substantial responder rates in a routine clinical setting including a wide range of patients.

A systematic review of Intensive Comprehensive Aphasia Programmes - who takes part, what is measured, what are the outcomes?

PURPOSE

This study synthesizes participant and outcome data from peer-reviewed Intensive Comprehensive Aphasia Programme (ICAP) studies.

METHODS

A systematic review was conducted following PRISMA guidelines. Study eligibility criteria were specified in relation to population, intervention, comparison, outcome, and design considerations. Data were extracted according to six research questions. Narrative synthesis was used.

RESULTS

Twenty-one studies were included covering 13 ICAPs (N = 485, aged 18-86 years, between 11 and 335 months post-stroke). Twenty-seven participant selection criteria were identified. Fifty-six outcome measures spanning the WHO-ICF were used, with the majority assessing the body function domain. Only eight studies employed an experimental design with data appropriate for analysis and synthesis. Risk of bias was noted across this sub-group. Participants improved in word-finding, communication, activity/participation, and communication-related quality of life, and maintained their gains; however, except for word finding, evidence of effect came from isolated studies. Factors influencing outcomes were rarely considered. Some drop-outs, missed sessions, and fatigue were noted. Some studies reported IPD alongside group analyses.

CONCLUSIONS

ICAP selection criteria need justification and should contribute to the understanding of candidacy for this treatment model. Rationalisation of ICAP treatment content and outcome measurement is required, spanning all WHO-ICF domains. Employment of the core outcome set for aphasia would enable data synthesis and facilitate comparisons between the ICAP and other therapy models.

A feasibility randomised waitlist-controlled trial of a personalised multi-level language treatment for people with aphasia: The remote LUNA study

BACKGROUND

Stroke survivors with aphasia want to improve their everyday talking (discourse). In current UK practice, 90% of speech and language therapists believe discourse assessment and treatment is part of their role but are hampered by barriers in resources, time and expertise. There is a clinical need for well-articulated discourse assessment and treatments. LUNA is a multi-level treatment targeting words, sentences and discourse macrostructure in personal stories that addresses this clinical need.

OBJECTIVES

This study aimed to assess the feasibility and acceptability of LUNA trial procedures in a randomised waitlist-controlled trial; and to evaluate preliminary efficacy.

METHODS

This paper reports a phase II, waitlist-controlled, proof-of-concept feasibility trial. Participants with chronic aphasia (n = 28) were recruited from the community and randomised to an Immediate (n = 14) or Delayed (n = 14) group. LUNA treatment was delivered twice weekly for 10 weeks via the videoconferencing technology, Zoom. Feasibility was assessed in terms of participant recruitment and retention, adherence, missing data, and treatment fidelity. Preliminary treatment efficacy was assessed in terms of between group differences in outcome measures relating to discourse, language, and psychosocial state.

RESULTS

The remote LUNA trial was feasible: 85% of those eligible consented to the trial; trial retention was 86%; 87% of treatment sessions were delivered as scheduled, and 79% of participants completed 80%+ of the treatment programme; data was missing only for participants who withdrew; treatment fidelity was high at 92% adherence; and only one clinical outcome measure demonstrated ceiling effects. ANCOVA analysis of the clinical outcome measures revealed group differences with medium and large effect sizes, indicating, improvements in the production of words, sentences, discourse macrostructure, overall language functioning (WAB-R), and psychosocial state (VAMS) following LUNA treatment. For most outcomes measured, similar treatment benefits were suggested in a secondary, non-parametric analysis.

CONCLUSIONS

Large-scale evaluation of the clinical efficacy and cost-effectiveness of LUNA is warranted and supported by these findings.

Qualitative Exploration of Speech Pathologists' Experiences and Priorities for Aphasia Service Design: Initial Stage of an Experience-Based Co-Design Project to Improve Aphasia Services

INTRODUCTION AND AIMS

Stroke survivors with aphasia (impaired language/communication) have poor outcomes and gaps in the clinical implementation of best practice contribute to this. Little is known, however, about speech pathologist perspectives on the touchpoints (key moments shaping experiences) in the clinical care pathway that have the greatest impact on service delivery nor how this varies by geographical location. We explored the experiences of speech pathologists who provide aphasia services to establish priorities for improvement and design.

METHODS AND ANALYSIS

This is the initial experience gathering and priority identification stage of an experience-based co-design (EBCD) project. Speech pathologists were recruited from 21 geographically diverse Hospital and Health Services in Queensland, Australia. Speech pathologists working in acute, rehabilitation and community services shared positive and negative experiences of delivering aphasia care in interviews and focus groups. Experiential data were analysed using qualitative thematic analysis to determine touchpoints. Priorities for service design were identified using an adapted nominal group technique.

RESULTS

Speech pathologists (n = 62) participated in 16 focus groups and nine interviews and shared 132 experiences of delivering aphasia care. Providing care in teams with poor awareness of the impacts of aphasia was identified as a key challenge, as poor patient-provider communication was perceived to increase risk of adverse outcomes for patients. Speech pathologists identified areas for improvement related to their own professional needs (e.g., greater access to clinical supervision); collaborative health care (e.g., better coordination and interdisciplinary care to increase therapy time); and the service context and environment (e.g., psychological services able to support diverse communication needs).

CONCLUSIONS

Speech pathologist delivery of aphasia services could be improved through increased access to clinical supervision, opportunities for peer debriefing and interdisciplinary care. Priorities for service design varied by geographical location and included: education to support care transitions (remote areas), improved referral pathways and service linkage (regional areas) and dedicated aphasia staffing (metropolitan areas).

PATIENT OR PUBLIC CONTRIBUTION

A consumer advisory committee comprising people with aphasia (n = 3, authors K.M., K.D. and B.A.), their significant others (n = 2, authors J.D. and P.M.), and a Cultural Capability Officer (author G.B.) guided this research. The team: (1) reviewed participant information; (2) co-designed surveys and workshop resources; (3) copresented research outcomes and contributed to publications. Research questions and study design (e.g., analysis methods and assessment measures) were developed by the research team (authors L.A., V.J.P., D.A.C. and S.J.W.).

Acceptability, feasibility and preliminary efficacy of low-moderate intensity Constraint Induced Aphasia Therapy and Multi-Modality Aphasia Therapy in chronic aphasia after stroke

BACKGROUND

High-intensity Constraint-Induced Aphasia Therapy Plus (CIAT-Plus) and Multi-Modality Aphasia Therapy (M-MAT) are effective interventions for chronic post-stroke aphasia but challenging to provide in clinical practice. Providing these interventions may be more feasible at lower intensities, but comparative evidence is lacking. We therefore explored feasibility, acceptability, and preliminary efficacy of the treatments at a lower intensity.

METHODS

A multisite, single-blinded, randomized Phase II trial was conducted within the Phase III COMPARE trial. Groups of participants with chronic aphasia from the usual care arm of the COMPARE trial were randomized to M-MAT or CIAT-Plus, delivered at the same dose as the COMPARE trial but at lower intensity (6 hours/week × 5 weeks rather than 15 hours/week × 2 weeks). Blinded assessors measured aphasia severity (Western Aphasia Battery-Revised Aphasia Quotient), word retrieval, connected speech, multimodal communication, functional communication, and quality of life immediately post interventions and after 12 weeks. Feasibility and acceptability were explored.

RESULTS

Of 70 eligible participants, 77% consented to the trial; 78% of randomized participants completed intervention and 98% of assessment visits were conducted. Fatigue and distress ratings were low with no related withdrawals. Adverse events related to the trial (n = 4) were mild in severity. Statistically significant treatment effects were demonstrated on word retrieval and functional communication and both interventions were equally effective.

CONCLUSIONS

Low-moderateintensity CIAT-Plus and M-MAT were feasible and acceptable. Both interventions show preliminary efficacy at a low-moderate intensity. These results support a powered trial investigating these interventions at a low-moderate intensity.

Identifying the Active Ingredients of a Computerized Speech and Language Therapy Intervention for Poststroke Aphasia: Multiple Methods Investigation Alongside a Randomized Controlled Trial

BACKGROUND

Aphasia is a communication disorder affecting more than one-third of stroke survivors. Computerized Speech and Language Therapy (CSLT) is a complex intervention requiring computer software, speech and language therapists, volunteers, or therapy assistants, as well as self-managed practice from the person with aphasia. CSLT was found to improve word finding, a common symptom of aphasia, in a multicenter randomized controlled trial (Clinical and Cost Effectiveness of Computer Treatment for Aphasia Post Stroke [Big CACTUS]).

OBJECTIVE

This study provides a detailed description of the CSLT intervention delivered in the Big CACTUS trial and identified the active ingredients of the intervention directly associated with improved word finding for people with aphasia.

METHODS

We conducted a multiple methods study within the context of a randomized controlled trial. In study 1, qualitative interviews explored key informants' understanding of the CSLT intervention, how the components interacted, and how they could be measured. Qualitative data were transcribed verbatim and analyzed thematically. Qualitative findings informed the process measures collected as part of a process evaluation of the CSLT intervention delivered in the Big CACTUS trial. In study 2, quantitative analyses explored the relationship between intervention process measures (length of computer therapy access; therapists' knowledge of CSLT; degree of rationale for CSLT tailoring; and time spent using the software to practice cued confrontation naming, noncued naming, and using words in functional sentences) and change in word-finding ability over a 6-month intervention period.

RESULTS

Qualitative interviews were conducted with 7 CSLT approach experts. Thematic analysis identified four overarching components of the CSLT approach: (1) the StepByStep software (version 5; Steps Consulting Ltd), (2) therapy setup: tailoring and personalizing, (3) regular independent practice, and (4) support and monitoring. Quantitative analyses included process and outcome data from 83 participants randomized to the intervention arm of the Big CACTUS trial. The process measures found to be directly associated with improved word-finding ability were therapists providing a thorough rationale for tailoring the computerized therapy exercises and the amount of time the person with aphasia spent using the computer software to practice using words in functional sentences.

CONCLUSIONS

The qualitative exploration of the CSLT approach provided a detailed description of the components, theories, and mechanisms underpinning the intervention and facilitated the identification of process measures to be collected in the Big CACTUS trial. Quantitative analysis furthered our understanding of which components of the intervention are associated with clinical improvement. To optimize the benefits of using the CSLT approach for word finding, therapists are advised to pay particular attention to the active ingredients of the intervention: tailoring the therapy exercises based on the individual's specific language difficulties and encouraging people with aphasia to practice the exercises focused on saying words in functional sentences.

Intensive and comprehensive aphasia therapy-a survey of the definitions, practices and views of speech and language therapists in the United Kingdom

BACKGROUND

Research evidence suggests aphasia therapy must be delivered at high intensity to effect change. Comprehensive therapy, addressing all domains of the International Classification of Functioning, Disability and Health, is also called for by people with aphasia and their families. However, aphasia therapy is rarely intense or comprehensive. Intensive Comprehensive Aphasia Programmes (ICAPs) were designed to address this challenge, but such programmes are not widely implemented.

AIMS

This study surveyed the views of UK-based speech and language therapists (SLTs) regarding intensive and comprehensive aphasia therapy. It explored definitions of intensive and comprehensive therapy, patterns of provision, views about candidacy and barriers/facilitators. It also investigated awareness of ICAPs and perceived potential of this service model. Differences across UK regions and workplace settings were explored.

METHODS & PROCEDURES

An e-survey ran for 5 months. Quantitative data were analysed using descriptive and inferential statistics. Qualitative free text comments were analysed using content analysis.

OUTCOMES & RESULTS

Two hundred twenty-seven respondents engaged in the e-survey. Definitions of intensive aphasia therapy did not reach UK clinical guideline/research-level thresholds for most of the sample. Those providing more therapy provided definitions with higher standards of intensity. Mean therapy delivered was 128 min/week. Geographical location and workplace setting influenced the amount of therapy delivered. The most frequently delivered therapy approaches were functional language therapy and impairment-based therapy. Cognitive disability and fatigue were concerns for therapy candidacy. Barriers included lack of resources and low levels of optimism that issues could be solved. 50% of respondents were aware of ICAPs and 15 had been involved in ICAP provision. Only 16.5% felt their service could be reconfigured to deliver an ICAP.

CONCLUSIONS & IMPLICATIONS

This e-survey evidences a mismatch between an SLT's concept of intensity and that espoused by clinical guidelines/research. Geographical variations in intensity are concerning. Although a wide range of therapy approaches are offered, certain aphasia therapies are delivered more frequently. Awareness of ICAPs was relatively high, but few respondents had experience of this model or felt it could be executed in their context. Further initiatives are needed if services are to move from a low-dose or non-comprehensive model of delivery. Such initiatives might include but not be confined to wider uptake of ICAPs. Pragmatic research might also explore which treatments are efficacious with a low-dose model of delivery, given that this model is dominant in the United Kingdom. These clinical and research implications are raised in the discussion.

WHAT THIS PAPER ADDS

What is already known on this subject There is a gap between the high intensity of aphasia treatment provided in research versus mainstream clinical settings. A lower standard of 45 min/day set by UK clinical guidelines is also not achieved. Although speech and language therapists (SLTs) provide a wide range of therapies, they typically focus on impairment-based approaches. What this study adds This is the first survey of UK SLTs asking about their concept of intensity in aphasia therapy and what types of aphasia therapy they provide. It explores geographical and workplace variations and barriers and facilitators to aphasia therapy provision. It investigates Intensive Comprehensive Aphasia Programmes (ICAPs) in a UK context. What are the clinical implications of this work? There are barriers to the provision of intensive and comprehensive therapy in the United Kingdom and reservations about the feasibility of ICAPs in a mainstream UK context. However, there are also facilitators to aphasia therapy provision and evidence that a small proportion of UK SLTs are providing intensive/comprehensive aphasia therapy). Dissemination of good practice is necessary and suggestions for increasing intensity of service provision are listed in the discussion.

Elizabeth Usher memorial lecture: Beyond our practice borders-using a biopsychosocial framework to improve long-term outcomes for people living with aphasia

Purpose: Over 140 000 Australians live with aphasia after stroke, with this number of people living with aphasia increasing significantly when aphasia arising from traumatic brain injury, neoplasm, and infectious and progressive neurological diseases is also included. The resulting communication disability frequently compromises every aspect of daily life, significantly impacting everyday activity, employment, social participation, mental health, identity, and family functioning. Rehabilitation services rarely meet the needs of this group who have, for example, poorer healthcare outcomes than stroke peers without aphasia, nor address long-term recovery and support needs.Method: In this discussion paper, I argue that given the broad impacts of aphasia, a biopsychosocial approach to aphasia rehabilitation is required. Rehabilitation must include: interventions to improve the communication environment; programs that directly target identity, wellbeing, and mental health; and therapies focusing on functional activity, communication participation, and long-term self-management.Result: The evidence for these approaches is mounting and includes strongly stated consumer needs. I discuss the need for multidisciplinary involvement and argue that for speech-language pathologists to achieve such comprehensive service provision, an expanded scope of practice is required.Conclusion: There is a need to rethink standard therapy approaches, timeframes, and funding mechanisms. It is time to reflect on our practice borders to ask what must change and define how change can be achieved.

"Self-management has to be the way of the future": Exploring the perspectives of speech-language pathologists who work with people with aphasia

PURPOSE

Healthcare models have incorporated self-management approaches to facilitate increased patient responsibility for chronic condition management. As aphasia is a chronic condition, self-management may be beneficial for people with aphasia; however, the possible impacts of the language disorder on self-management must be acknowledged and addressed. Speech-language pathologists would likely be principal providers of self-management support; therefore, their perspectives should be sought when considering development of aphasia self-management approaches. This study aims to explore speech-language pathologist perspectives of aphasia self-management.

METHOD

In-depth, semi-structured interviews conducted with 15 speech-language pathologists in Australia. Interview data analysed using qualitative content analysis.

RESULT

Aphasia self-management was viewed as a person- and family-centred approach enabling comprehensive long-term care for people with aphasia and promoting control, responsibility, and independence. Speech-language pathologists were seen to have a substantial role providing self-management support and consultation, and training was required to expand this role. Communication partners and peer support were highly valued. Personal and environmental factors may influence successful aphasia self-management. Differences between aphasia self-management and chronic condition self-management were considered.

CONCLUSION

Self-management could facilitate long-term sustainable aphasia management. Aphasia self-management approaches should factor in how to maximise communication partner and peer support. Aphasia-friendly self-management resources are necessary.

Post-Stroke Experiences and Rehabilitation Needs of Community-Dwelling Chinese Stroke Survivors: A Qualitative Study

Stroke survivors encounter significant limitations in daily life activities and face increased risk of health complications such as stroke recurrence. Considering the escalating demand for personalised community rehabilitation services, this qualitative study was conducted to understand the current recovery experiences, needs, and expectations of community-dwelling stroke survivors. Fifty stroke survivors were recruited from two tertiary teaching hospitals and community centres in two provinces in mainland China. Semi-structured interviews were carried out, and participants were asked to describe their experiences of stroke, current lifestyles, exercise habits, and rehabilitation needs and expectations. Resulting data were thematically analysed. The majority of participants were first-time stroke survivors (80%) and lived with their family or caregivers (92%). Four main themes and twelve sub-themes emerged from the data: (1) shifts in social life, (2) shaken sense of self and perceived helplessness, (3) complex rehabilitation needs, and (4) perceptions and patterns of physical activity. Findings suggest that though survivors recognised their need for further rehabilitation, their demands remained unmet due to a combination of personal and external factors such as limited mobility and the absence of supportive companions and accessible facilities. The enhancement and diversification of home rehabilitation strategies are therefore necessary to make community rehabilitation more accessible and equitable.

Precision rehabilitation for aphasia by patient age, sex, aphasia severity, and time since stroke? A prespecified, systematic review-based, individual participant data, network, subgroup meta-analysis

BACKGROUND

Stroke rehabilitation interventions are routinely personalized to address individuals' needs, goals, and challenges based on evidence from aggregated randomized controlled trials (RCT) data and meta-syntheses. Individual participant data (IPD) meta-analyses may better inform the development of precision rehabilitation approaches, quantifying treatment responses while adjusting for confounders and reducing ecological bias.

AIM

We explored associations between speech and language therapy (SLT) interventions frequency (days/week), intensity (h/week), and dosage (total SLT-hours) and language outcomes for different age, sex, aphasia severity, and chronicity subgroups by undertaking prespecified subgroup network meta-analyses of the RELEASE database.

METHODS

MEDLINE, EMBASE, and trial registrations were systematically searched (inception-Sept2015) for RCTs, including ⩾ 10 IPD on stroke-related aphasia. We extracted demographic, stroke, aphasia, SLT, and risk of bias data. Overall-language ability, auditory comprehension, and functional communication outcomes were standardized. A one-stage, random effects, network meta-analysis approach filtered IPD into a single optimal model, examining SLT regimen and language recovery from baseline to first post-intervention follow-up, adjusting for covariates identified a-priori. Data were dichotomized by age (⩽/> 65 years), aphasia severity (mild-moderate/ moderate-severe based on language outcomes' median value), chronicity (⩽/> 3 months), and sex subgroups. We reported estimates of means and 95% confidence intervals. Where relative variance was high (> 50%), results were reported for completeness.

RESULTS

959 IPD (25 RCTs) were analyzed. For working-age participants, greatest language gains from baseline occurred alongside moderate to high-intensity SLT (functional communication 3-to-4 h/week; overall-language and comprehension > 9 h/week); older participants' greatest gains occurred alongside low-intensity SLT (⩽ 2 h/week) except for auditory comprehension (> 9 h/week). For both age-groups, SLT-frequency and dosage associated with best language gains were similar. Participants ⩽ 3 months post-onset demonstrated greatest overall-language gains for SLT at low intensity/moderate dosage (⩽ 2 SLT-h/week; 20-to-50 h); for those > 3 months, post-stroke greatest gains were associated with moderate-intensity/high-dosage SLT (3-4 SLT-h/week; ⩾ 50 hours). For moderate-severe participants, 4 SLT-days/week conferred the greatest language gains across outcomes, with auditory comprehension gains only observed for ⩾ 4 SLT-days/week; mild-moderate participants' greatest functional communication gains were associated with similar frequency (⩾ 4 SLT-days/week) and greatest overall-language gains with higher frequency SLT (⩾ 6 days/weekly). Males' greatest gains were associated with SLT of moderate (functional communication; 3-to-4 h/weekly) or high intensity (overall-language and auditory comprehension; (> 9 h/weekly) compared to females for whom the greatest gains were associated with lower-intensity SLT (< 2 SLT-h/weekly). Consistencies across subgroups were also evident; greatest overall-language gains were associated with 20-to-50 SLT-h in total; auditory comprehension gains were generally observed when SLT > 9 h over ⩾ 4 days/week.

CONCLUSIONS

We observed a treatment response in most subgroups' overall-language, auditory comprehension, and functional communication language gains. For some, the maximum treatment response varied in association with different SLT-frequency, intensity, and dosage. Where differences were observed, working-aged, chronic, mild-moderate, and male subgroups experienced their greatest language gains alongside high-frequency/intensity SLT. In contrast, older, moderate-severely impaired, and female subgroups within 3 months of aphasia onset made their greatest gains for lower-intensity SLT. The acceptability, clinical, and cost effectiveness of precision aphasia rehabilitation approaches based on age, sex, aphasia severity, and chronicity should be evaluated in future clinical RCTs.

Management of communication disability in the first 90 days after stroke: a scoping review

INTRODUCTION

People with communication disability after stroke need interventions to optimise healthcare communication and rehabilitation outcomes. Current evidence syntheses do not adequately inform the management of communication disability during the first 90 days post-stroke.

PURPOSE

To explore the scope of literature for the management of communication disability in the first 90 days after stroke.

MATERIALS AND METHODS

A scoping review was conducted using a systematic keyword search of six databases. A descriptive synthesis was generated using communication-related domains related to the biopsychosocial framework of the International Classification of Functioning, Disability, and Health (ICF).

RESULTS

A total of 129 studies met eligibility criteria. Aphasia was the most frequently addressed communication disability after stroke (76/129 studies) with a paucity of evidence investigating other acquired neurogenic communication impairments. Management predominantly focused on communication-related: body functions and structures (62 studies) (e.g., linguistic-behavioural therapies), followed by environmental factors (39 studies) (e.g., communication partner training/support); activities and participation (15 studies) (e.g., augmentative and alternative communication); and personal factors (13 studies) (e.g., assessment of depression after aphasia).

CONCLUSION

A coordinated, integrated approach to developing and testing acute and subacute interventions for all communication disabilities across all communication-related domains is required.IMPLICATIONS FOR REHABILITATIONInterdisciplinary stroke clinicians need to manage communication disabilities in the first 90 days after stroke to optimise healthcare communication and rehabilitation outcomes.There is some evidence to guide clinicians in aphasia management but less in other disabilities of speech and cognitive functioning.Most interventions to inform clinical practice address communication-related body functions and structures (e.g., linguistic and speech therapies). Clinicians need to address all domains and more evidence is needed to address environmental factors (e.g., communication support); activities and participation (e.g., person-centred goal setting); and personal factors (e.g., psychological care).

Intensive Comprehensive Aphasia Programmes: a systematic scoping review and analysis using the TIDieR checklist for reporting interventions

PURPOSE

Aphasia is an acquired language disorder that typically occurs as a result of a stroke. People with aphasia experience communication difficulties and risk secondary impacts, for example, affecting social and work life and mental health. Intensive Comprehensive Aphasia Programmes (ICAPs) aims to address the multiple consequences of aphasia using intensive intervention and a wide range of therapy approaches. Although basic parameters of ICAP intervention have been defined, a fuller characterisation is needed. This systematic scoping review aimed to determine what constitutes an ICAP.

METHODS

Peer-reviewed and Grey databases were searched for articles on ICAPs using Joanna Brigg's Institute methodology. Data was extracted following the Template for Intervention Description and Replication (TIDieR) checklist for reporting interventions and synthesised using a narrative synthesis.

RESULTS AND CONCLUSIONS

17 ICAPs were reported in 20 peer-reviewed literature sources (9 ICAPs supplemented by Grey literature sources). There were high degrees of variation in dose, professionals involved, and no qualitative data from participants. Of note, ICAP intervention was highly tailored to individual participants on the same ICAP, and intervention content varied between ICAPs. ICAPs appear to be rationalised as intensive impairment-based programmes with other components added for comprehensiveness. Stronger rationale and a logic model are required to justify the core components of ICAPs. The input of stakeholders into designing future ICAP interventions is recommended.IMPLICATIONS FOR REHABILITATIONThe ICAP model is in its infancy when it comes to mainstream clinical application as only the intensity component of the ICAP has clear theoretical underpinning as reported in the peer-reviewed literature.There have been clinical uptakes of the ICAP model which is likely to continue and is valid in the context of an under-researched area of aphasia therapy and on a background of a less than perfect relationship between evidence base and practice.Aspects of the ICAP model are valid for clinicians to implement, for example, intensive evidence-based aphasia therapy in combination with therapy which addresses some of the broader implications of aphasia, for example, social isolation.Clinicians can use the ICAP model to review their existing service provision and explore whether their service provides aphasia therapy that addresses the multiple aspects of aphasia (i.e., ensuring the focus is not only on impairment-based therapy).

Common Neuroanatomical Substrate of Cholinergic Pathways and Language-Related Brain Regions as an Explanatory Framework for Evaluating the Efficacy of Cholinergic Pharmacotherapy in Post-Stroke Aphasia: A Review

Despite the relative scarcity of studies focusing on pharmacotherapy in aphasia, there is evidence in the literature indicating that remediation of language disorders via pharmaceutical agents could be a promising aphasia treatment option. Among the various agents used to treat chronic aphasic deficits, cholinergic drugs have provided meaningful results. In the current review, we focused on published reports investigating the impact of acetylcholine on language and other cognitive disturbances. It has been suggested that acetylcholine plays an important role in neuroplasticity and is related to several aspects of cognition, such as memory and attention. Moreover, cholinergic input is diffused to a wide network of cortical areas, which have been associated with language sub-processes. This could be a possible explanation for the positive reported outcomes of cholinergic drugs in aphasia recovery, and specifically in distinct language processes, such as naming and comprehension, as well as overall communication competence. However, evidence with regard to functional alterations in specific brain areas after pharmacotherapy is rather limited. Finally, despite the positive results derived from the relevant studies, cholinergic pharmacotherapy treatment in post-stroke aphasia has not been widely implemented. The present review aims to provide an overview of the existing literature in the common neuroanatomical substrate of cholinergic pathways and language related brain areas as a framework for interpreting the efficacy of cholinergic pharmacotherapy interventions in post-stroke aphasia, following an integrated approach by converging evidence from neuroanatomy, neurophysiology, and neuropsychology.

Dosage Frequency Effects on Treatment Outcomes Following Self-managed Digital Therapy: Retrospective Cohort Study

BACKGROUND

Although the efficacy of high-dose speech-language therapy (SLT) for individuals with poststroke aphasia has been established in the literature, there is a gap in translating these research findings to clinical practice. Therefore, patients continue to receive suboptimal amounts of SLT, with negative consequences for their functional communication recovery. Recent research has identified self-managed digital health technology as one way to close the dosage gap by enabling high-intensity therapy unrestricted by clinician availability or other practical constraints. However, there is limited empirical evidence available to rehabilitation professionals to guide dose prescriptions for self-managed SLT despite their increasing use in the COVID-19 era and likely beyond.

OBJECTIVE

This study aims to leverage real-world mobile health data to investigate the effects of varied dosage frequency on performance outcomes for individuals with poststroke speech, language, and cognitive deficits following a 10-week period of self-managed treatment via a commercially available digital health platform.

METHODS

Anonymized data from 2249 poststroke survivors who used the Constant Therapy app between late 2016 and 2019 were analyzed. The data included therapy tasks spanning 13 different language and cognitive skill domains. For each patient, the weekly therapy dosage was calculated based on the median number of days per week of app use over the 10-week therapy period, binned into groups of 1, 2, 3, 4, or ≥5 days per week. Linear mixed-effects models were run to examine change in performance over time as a function of dosage group, with post hoc comparisons of slopes to evaluate the performance gain associated with each additional day of practice.

RESULTS

Across all skill domains, linear mixed-effects model results showed that performance improvement was significantly greater for patients who practiced 2 (β=.001; t_15,355=2.37; P=.02), 3 (β=.003; t₉₇₃₈=5.21; P<.001), 4 (β=.005; t₉₂₈₉=7.82; P<.001), or ≥5 (β=.005; t₆₃₄₃=8.14; P<.001) days per week compared with those who only practiced for 1 day per week. Post hoc comparisons confirmed an incremental dosage effect accumulating with each day of practice (ie, 1 day vs 2 days, 2 days vs 3 days, and 3 days vs 4 days), apart from 4 days versus ≥5 days of practice per week. The result of greater improvement for higher versus lower dosage frequency groups was true not only across all domains but also within a majority of individual subdomains.

CONCLUSIONS

The findings from this study demonstrated that increased dosage frequency is associated with greater therapy gains over a 10-week treatment period of self-managed digital therapy. The use of real-world data maximizes the ecological validity of study results and makes the findings more generalizable to clinical settings. This study represents an important step toward the development of optimal dose recommendations for self-managed SLT.

Understanding the Economics of Aphasia: Recent Findings from Speech and Language Research

In recent years, stakeholders engaged in the study, treatment, and understanding of aphasia outcomes have emphasized the need for greater transparency regarding the economics of aphasia rehabilitation. Most notably, third-party payers and clinicians have a keen interest in understanding the resources used to treat aphasia, particularly the cost-effectiveness and value of aphasia treatments. In this article, we review the current literature related to the economic burden of aphasia and the cost and cost-effectiveness of aphasia treatments. To date, relatively few scholars have attempted to study the efficiency, scale, and scope related to the economics of aphasia and the cost-effectiveness of aphasia treatment. While studies of the cost-effectiveness of aphasia treatments have shown rehabilitative treatments conform to established quality and cost benchmarks, the continued progress and developments in the treatment of aphasia and measurement of clinical outcomes has left many areas unstudied. We highlight the need for greater emphasis on the cost-effectiveness of aphasia treatments in addition to the traditional focus on the efficacy of treatment outcomes.

Determinants of Antidepressant Treatment and Outpatient Rehabilitation Within the First Year After Stroke

This study aims to identify individual determinants of antidepressant treatment and outpatient rehabilitation after stroke. People with ischemic stroke (N = 303) recruited at 2 inpatient rehabilitation clinics were included into a prospective longitudinal study with follow-up telephone interviews 6 and 12 months later. Participants reported on their use of antidepressant medication and psychotherapy as well as physical, occupational, speech, and neuropsychological therapy. The use of antidepressants at discharge (n = 65, 23.8%) was predicted by the severity of depressive symptoms, severity of stroke, history of depression, and use of antidepressants at admission (all p < .05, R²= .55). The number of outpatient rehabilitation services used at follow-ups was predicted by higher functional and cognitive impairment, higher education, younger age, severity of depressive symptoms, and lower self-efficacy (all p < .05; R²_6M = .24, R²_12M = .49). The relevance of identified determinants for the improvement of treatment rates after stroke is discussed.

Using experience-based codesign to coproduce aphasia rehabilitation services: study protocol

INTRODUCTION

Aphasia is an impairment of language that occurs in 30%-40% of stroke survivors. This often chronic condition results in poor outcomes for the individual with aphasia and their family. Long-term aphasia management is limited, with few people receiving sufficient services by 6-12 months postonset. We present a protocol for the development of coproduced aphasia service elements. We will use experience-based codesign (EBCD), an approach that enables service users and providers to collaboratively develop services and care pathways. Drawing on the experiences of people with aphasia, their families and clinicians we will establish priorities for the development of new services and later work together to codesign them.

METHODS AND ANALYSIS

This research will be coproduced with people with aphasia (n=30-60), their families (n=30-60) and speech pathologists (n=30-60) in Queensland, Australia, using EBCD. A consumer advisory committee will provide oversight and advice throughout the research. In phase 1, we will use semistructured interviews and the nominal group technique to explore experiences and unmet needs in aphasia rehabilitation. Data will be analysed using thematic analysis and the resulting themes will be prioritised in multistakeholder focus groups. Outcomes of phase 1 will inform future research (phase 2) to codesign services. Financial costs and participant experiences of EBCD will be measured.

ETHICS AND DISSEMINATION

Human Research Ethics Committee approval for phase 1 has been obtained (HREC/2020/QRBW/61368). Results will be reported in peer-reviewed journal articles, presented at relevant conferences and, following EBCD suggested best practice, fed back to participants and community members at a celebratory event at completion of the project. The inclusion of service users in all stages of research will facilitate an integrated approach to knowledge translation. A summary of research findings will be made available to participating sites.

Novel Advances to Post-Stroke Aphasia Pharmacology and Rehabilitation

Aphasia is one of the most common clinical features of functional impairment after a stroke. Approximately 21–40% of stroke patients sustain permanent aphasia, which progressively worsens one’s quality of life and rehabilitation outcomes. Post-stroke aphasia treatment strategies include speech language therapies, cognitive neurorehabilitation, telerehabilitation, computer-based management, experimental pharmacotherapy, and physical medicine. This review focuses on current evidence of the effectiveness of impairment-based aphasia therapies and communication-based therapies (as well as the timing and optimal treatment intensities for these interventions). Moreover, we present specific interventions, such as constraint-induced aphasia therapy (CIAT) and melodic intonation therapy (MIT). Accumulated data suggest that using transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) is safe and can be used to modulate cortical excitability. Therefore, we review clinical studies that present TMS and tDCS as (possible) promising therapies in speech and language recovery, stimulating neuroplasticity. Several drugs have been used in aphasia pharmacotherapy, but evidence from clinical studies suggest that only nootropic agents, donepezil and memantine, may improve the prognosis of aphasia. This article is an overview on the current state of knowledge related to post-stroke aphasia pharmacology, rehabilitation, and future trends.

'I hated being ghosted' - The relevance of social participation for living well with post-stroke aphasia: Qualitative interviews with working aged adults

Background

In the context of increasing incidence of stroke in working aged adults, there is a specific need to explore the views of working aged adults with post‐stroke aphasia, whose communication difficulties may result in restricted social participation, loss of employment and changed relationship and parenting roles. This study aimed to explore the perspectives of working aged adults with post‐stroke aphasia in relation to social participation and living well with aphasia (LWA).

Design and participants

We conducted qualitative interviews with 14 people with post‐stroke aphasia (PWA). Data were analysed following principles of reflexive, thematic analysis.

Patient or Public Contribution: A Public and Patient Involvement aphasia advisory group inputted into the study design and interpretation of data.

Results

Social participation spanned 5 themes: Relationships and roles; Social support; Peer network, Aphasia awareness; and Employment and training. Meaningful, interesting social participation for LWA is individually defined. Working aged PWA may require flexible support with parenting, accessing a diverse social network and finding opportunities for meaningful social connection, training and employment.

Conclusions

The findings extend knowledge of social participation in the context of LWA for working aged adults by elucidating the individually defined nature of meaningful participation and how PWA may need flexible support with parenting, accessing a diverse social network and training and employment. For aphasia research, policy and services to be relevant, it is crucial that working aged PWA are meaningfully involved in setting the aphasia agenda.

Self-managed, computerised word finding therapy as an add-on to usual care for chronic aphasia post-stroke: An economic evaluation

OBJECTIVE

To examine the cost-effectiveness of self-managed computerised word finding therapy as an add-on to usual care for people with aphasia post-stroke.

DESIGN

Cost-effectiveness modelling over a life-time period, taking a UK National Health Service (NHS) and personal social service perspective.

SETTING

Based on the Big CACTUS randomised controlled trial, conducted in 21 UK NHS speech and language therapy departments.

PARTICIPANTS

Big CACTUS included 278 people with long-standing aphasia post-stroke.

INTERVENTIONS

Computerised word finding therapy plus usual care; usual care alone; usual care plus attention control.

MAIN MEASURES

Incremental cost-effectiveness ratios (ICER) were calculated, comparing the cost per quality adjusted life year (QALY) gained for each intervention. Credible intervals (CrI) for costs and QALYs, and probabilities of cost-effectiveness, were obtained using probabilistic sensitivity analysis. Subgroup and scenario analyses investigated cost-effectiveness in different subsets of the population, and the sensitivity of results to key model inputs.

RESULTS

Adding computerised word finding therapy to usual care had an ICER of £42,686 per QALY gained compared with usual care alone (incremental QALY gain: 0.02 per patient (95% CrI: -0.05 to 0.10); incremental costs: £732.73 per patient (95% CrI: £674.23 to £798.05)). ICERs for subgroups with mild or moderate word finding difficulties were £22,371 and £21,262 per QALY gained respectively.

CONCLUSION

Computerised word finding therapy represents a low cost add-on to usual care, but QALY gains and estimates of cost-effectiveness are uncertain. Computerised therapy is more likely to be cost-effective for people with mild or moderate, as opposed to severe, word finding difficulties.

A Virtual, Randomized, Control Trial of a Digital Therapeutic for Speech, Language, and Cognitive Intervention in Post-stroke Persons With Aphasia

Background: Post-stroke aphasia is a chronic condition that impacts people's daily functioning and communication for many years after a stroke. Even though these individuals require sustained rehabilitation, they face extra burdens to access care due to shortages in qualified clinicians, insurance limitations and geographic access. There is a need to research alternative means to access intervention remotely, such as in the case of this study using a digital therapeutic.

Objective: To assess the feasibility and clinical efficacy of a virtual speech, language, and cognitive digital therapeutic for individuals with post-stroke aphasia relative to standard of care.

Methods: Thirty two participants completed the study (experimental: average age 59.8 years, 7 female, 10 male, average education: 15.8 years, time post-stroke: 53 months, 15 right handed, 2 left handed; control: average age 64.2 years, 7 female, 8 male, average education: 15.3 years, time post-stroke: 36.1 months, 14 right handed, 1 left handed). Patients in the experimental group received 10 weeks of treatment using a digital therapeutic, Constant Therapy-Research (CT-R), for speech, language, and cognitive therapy, which provides evidence-based, targeted therapy with immediate feedback for users that adjusts therapy difficulty based on their performance. Patients in the control group completed standard of care (SOC) speech-language pathology workbook pages.

Results: This study provides Class II evidence that with the starting baseline WAB-AQ score, adjusted by −0.69 for every year of age, and by 0.122 for every month since stroke, participants in the CT-R group had WAB-AQ scores 6.43 higher than the workbook group at the end of treatment. Additionally, secondary outcome measures included the WAB-Language Quotient, WAB-Cognitive Quotient, Brief Test of Adult Cognition by Telephone (BTACT), and Stroke and Aphasia Quality of Life Scale 39 (SAQOL-39), with significant changes in BTACT verbal fluency subtest and the SAQOL-39 communication and energy scores for both groups.

Conclusions: Overall, this study demonstrates the feasibility of a fully virtual trial for patients with post-stroke aphasia, especially given the ongoing COVID19 pandemic, as well as a safe, tolerable, and efficacious digital therapeutic for language/cognitive rehabilitation.

What are the factors that may influence the implementation of self-managed computer therapy for people with long term aphasia following stroke? A qualitative study of speech and language therapists' experiences in the Big CACTUS trial

PURPOSE

To explore speech and language therapists' (SLT) experiences of delivering therapy using a computerised self-management approach within a pragmatic trial, in order to identify and understand key factors that may influence the implementation of computerised approaches to rehabilitation for aphasia in routine practice.

METHODS

Qualitative semi-structured telephone interviews were conducted with eleven SLTs delivering computer therapy in the multisite Big CACTUS trial. The interviews were recorded, transcribed verbatim and analysed using thematic analysis in NVivo11.

RESULTS

Five themes with implications for implementation emerged: 1) characteristics of the intervention: complexity and adaptability 2) knowledge and beliefs about the intervention: familiarity with computers and the benefits of training; 3) patient needs and the service resource dilemma: "is there anything I can be doing on my computer at home?"; 4) networks and communications; 5) reflecting and evaluating: adaptations for sustainability.

CONCLUSIONS

Personalisation, feedback and volunteer/assistant support were viewed as benefits of this complex intervention. However, the same benefits required resources including therapist time in learning to use software, procuring it, personalising it, working with volunteers/assistants, and building relationships with IT departments which formed barriers to implementation. The discussion highlights the need to consider integration of computer and face-to-face therapy to support implementation and potentially optimise patient outcomes.IMPLICATIONS FOR REHABILITATIONBenefits of the self-managed computer approach to word finding therapy evaluated in the Big CACTUS trial included the ability to personalise content, to provide feedback, and provide support with volunteers or assistants depending on availability in different clinical contexts to enable repetitive self-managed practice of word finding.Whilst use of computer therapy approaches can facilitate self-management of practice and increased therapy hours in an efficient manner, services need to consider the resources required to implement and support the approach: costs of software and hardware SLT time required to learn to use the software, tailor and personalise it and manage volunteers/assistants.Readiness for successful adoption of computer approaches requires building of relationships and mutual understanding of requirements between SLT and IT departments within an organisation.For time efficiency, it is recommended that SLTs providing self-managed computer therapy approaches pilot the approach with each individual to check patient ability and engagement before fully investing SLT time in personalisation and tailoring of software.

The relevance of stroke care for living well with post-stroke aphasia: a qualitative interview study with working-aged adults

PURPOSE

This study aimed to explore the perspectives of working-aged adults with post-stroke aphasia (PWA) towards what has or would help them in living well with aphasia (LWA). This paper reports the findings in relation to stroke care and its relevance for LWA.

MATERIALS AND METHODS

This qualitative study was designed with input from a Public and Patient Involvement advisory group. We conducted in-depth, semi-structured interviews with 14 PWA. Data were analysed following principles of reflexive thematic analysis.

RESULTS

Support services and LWA spanned five themes: Inpatient care; Support in the community; Speech therapy; Mental health; and Aphasia education and training. Per the findings, all aspects of stroke care were affected and challenged by aphasia. Access to services and information was variable. PWA of working-age, their families and children need access to person-centred stroke care and information responsive to their changing needs at all stages of recovery. Healthcare workers must be equipped with aphasia competency.

CONCLUSIONS

The results highlight a need for equitable, transparent, responsive access to services, information and stroke liaison support. The findings extend knowledge of the importance of stroke care for supporting working-aged adults and their families to live well in the context of aphasia.Implications for rehabilitationThere is a need for equitable, transparent access to a responsive integrated pathway of stroke care to support living well with aphasia.People with aphasia post-stroke and their families need access to person-centred stroke care and information responsive to their changing needs at all stages of recovery.This includes flexible access to mental healthcare and speech and language therapy.In order to access relevant care, people with post-stroke aphasia need access to information and stroke liaison support.Training to improve aphasia competency is imperative for healthcare workers.

Factors Associated With Adherence to Self-Managed Aphasia Therapy Practice on a Computer-A Mixed Methods Study Alongside a Randomized Controlled Trial

Background: Aphasia is a communication disorder often acquired after a stroke. Independent use of specialist aphasia software on a home computer is a form of asynchronous tele-rehabilitation that can provide increased opportunity for practice of rehabilitation exercises. This study aimed to explore the factors associated with adherence to self-managed aphasia computer therapy practice. Method: A mixed methods exploration of adherence was conducted alongside the Big CACTUS randomized controlled trial [ISRCTN: 68798818]. The trial evaluated the clinical effectiveness of self-managed aphasia computer therapy. This study reports secondary analysis of data from participants randomized to the computer therapy group to investigate whether any demographic, clinical or intervention variables were associated with adherence to therapy practice. A sub-sample of the same participants took part in qualitative interviews exploring the factors perceived to influence the amount of aphasia computer therapy practice undertaken. Interviews were analyzed thematically. A convergence-coding matrix was used to triangulate the two sets of findings. Results: Data from 85 participants randomized to the computer therapy group were included in the quantitative analyses. At a clinical level, a greater length of time post-stroke was associated with higher adherence to self-managed aphasia therapy practice on a computer. At an intervention level, length of computer therapy access and therapist time supporting the participant were associated with greater adherence to computer therapy practice. Interviews with 11 patients and 12 informal carers identified a multitude of factors perceived to influence engagement with tele-rehabilitation by people with aphasia. The factors grouped around three themes: capability to use the computer therapy, having the opportunity to practice (external influences and technological issues) and motivation (beliefs, goals and intentions vs. personality, emotions, habit and reinforcement). Triangulation demonstrated convergence for the finding that participants' practiced computer-based therapy exercises more when they received increased support from a speech and language therapist. Conclusion: Clinicians delivering asynchronous tele-rehabilitation involving self-management of aphasia therapy practice on a computer should consider the factors found to be associated with engagement when deciding which patients may be suited to this option, as well as how they can be supported to optimize the amount of practice they engage in.

Supporting people with post-stroke aphasia to live well: A cross-sectional survey of Speech & Language Therapists in Ireland

Living well with post-stroke aphasia is supported by responsive, collaborative heath and related services, aphasia information and training for people with aphasia (PWA) and their social networks, and opportunities to contribute and participate autonomously in their communities. Several international surveys indicate shortcomings in the provision of long-term support and, in Ireland, while there is a lack of data around service provision for PWA, there is evidence that post-acute stroke services are fragmented and under-resourced. The aim of this study was to survey Speech & Language Therapists (SLTs), due to their unique role in aphasia management, to understand what SLT and related support services and aphasia information and training are currently available to support living well with aphasia in Ireland. We developed and piloted a self-administered, web-based cross-sectional survey with questions informed by a systematic review and qualitative evidence synthesis around living well with aphasia, and with input from a Public and Patient Involvement aphasia advisory group. Data from 95 SLTs working with PWA were analysed using descriptive statistics. Although SLT was generally available for PWA, the results highlight access barriers and evidence-practice gaps in terms of the amount, intensity and timing of SLT to be maximally effective and there was a lack of PWA input into service design and evaluation. Access to other relevant supports such as mental health services was inconsistent and there was a lack of community support for families. There were shortcomings in access to aphasia information/training for PWA, families, friends and other healthcare professionals. There is a need for a coordinated and standardised approach to supporting PWA across Ireland. This study addresses an evidence gap around the provision of stroke services for PWA and is part of a larger project aiming to produce recommendations for improving person-centred support to facilitate living well with aphasia.

The management of subacute and chronic vascular aphasia: an updated review

Background

Post-stroke aphasia (PSA) is an impairment of the generation or comprehension of language due to acute cerebrovascular lesions. Subacute phase span the 7th day to 24 weeks post-onset while > 6 months is termed chronic phase. Language recovery does not arise immediately in chronic PSA, unlike the acute phase. The majority of the treatment modalities in these two PSA phases are still in the infancy stage, facing dilemmas and considered experimental requiring constant updates. Hence, we aimed to upgrade the existing literature regarding available PSA management options, advances, and drawbacks pertaining to subacute and chronic phases.

Main text

In this review, we analyzed the management options for subacute and chronic vascular aphasia. MEDLINE, through PubMed, ScienceDirect, and Google Scholar were explored for English studies by utilizing the terms “stroke aphasia” Plus “vascular aphasia”; 160,753 articles were retrieved. The latest studies, published from 2016 to July 2020, were selected. Article headings and abstracts were analyzed for relevance and filtered; eventually, 92 articles were included in this review. Various management options were extracted as follows: noninvasive brain stimulation (NIBS), technology-based therapies, speech-language therapy (SLT), pharmacotherapy, music-based therapies, and psychosocial interventions.

Conclusion

The PSA therapy evolves towards more intense SLT therapy, yet the optimal dosage of the emerging high-intensity therapies is controversial. As spinal and cerebellar NIBS, Telespeech, and E-mental health mark PSA's future, distinct pharmacological options remain a dilemma. Across the continuum of care, PSA–depression comorbidity and inadequate PSA post-discharge education to patient’s families are the significant therapeutic challenges. Future therapeutic mechanisms, optimal dose/timing, and tolerability/safety exploration are obliged.

Design Considerations for Clinical Trials in Aphasia

The use of the randomised controlled trial (RCT) design to evaluate the effectiveness of new interventions in aphasia has increased in recent years in response to calls for high quality evidence of the effectiveness of interventions for this population. This view-point article highlights some of the important considerations when designing a trial for an aphasia intervention, illustrated with decisions made when designing the Big CACTUS RCT for self-managed computer-based word finding therapy in aphasia. Considerations outlined include whether an RCT is needed, readiness for conducting an RCT, choice of comparators, randomisation options, blinding/masking, selection of outcome measures, pragmatic versus explanatory approaches, and fidelity measurement.

Comparing higher and lower weekly treatment intensity for chronic aphasia: A systematic review and meta-analysis

Optimizing intensity for aphasia treatment is a high priority research issue for people with aphasia, their families and clinicians, and could result in healthcare cost savings. An important aspect of intensity is the frequency of intervention, or how regularly treatment should be provided each week. While principles of neuroplasticity endorse massed practice, cognitive psychology has established superiority of distributed practice within normal learning. Neither concept has been conclusively tested in aphasia. There have been many literature reviews of intensity in aphasia intervention, but most have not investigated treatment intensity whilst also ensuring that therapy dose and treatment type are identical between study groups. Some have also combined studies across acute, subacute and chronic aphasia. We searched systematically for studies directly comparing higher and lower weekly treatment frequency in chronic aphasia. Eight studies were retrieved and rated for methodological quality. Meta-analysis was completed for group and single case experimental designs. Results showed that there are few studies investigating treatment frequency in chronic aphasia and their quality is low-moderate. Meta-analyses were inconclusive due to limited data, but there was no indication of either schedule being superior. Further research directly comparing treatment schedules is needed.

Elizabeth Usher Memorial Lecture: Lost in Translation? Challenges and future prospects for a neurobiological approach to aphasia rehabilitation

While there has been considerable progress in conducting trials of aphasia therapy, there is no consistent evidence for long-term benefits of aphasia treatment, suggesting the need to reconsider current approaches. There are also no accurate methods for determining the amount, type and timing of aphasia therapy that should be provided for an individual. At the same time, there has been increasing interest in applying various principles of neuroplasticity to aphasia treatment and using measures of brain structure and function to predict recovery. This article will consider the potential of neuroplasticity principles and neurobiological predictors to improve our current approach to aphasia rehabilitation and optimise outcomes. Reviewing these principles highlights some of the challenges of translating animal model-based principles and emphases the need to also consider relevant theories of human learning. While considerable progress has been made in considering neurobiological principles and using measures of brain structure and function to predict recovery, there is significant work required to achieve the full potential of this neurobiological approach to aphasia management.

Closing the Digital Divide in Speech, Language, and Cognitive Therapy: Cohort Study of the Factors Associated With Technology Usage for Rehabilitation

BACKGROUND

For stroke, traumatic brain injury (TBI), and other neurologic conditions associated with speech-language disorders, speech and language therapy is the standard of care for promoting recovery. However, barriers such as clinician time constraints and insurance reimbursement can inhibit a patient's ability to receive the support needed to optimize functional gain. Although digital rehabilitation has the potential to increase access to therapy by allowing patients to practice at home, the clinical and demographic characteristics that impact a patient's level of engagement with technology-based therapy are currently unknown.

OBJECTIVE

This study aimed to evaluate whether the level of engagement with digital therapy differs by various patient characteristics, including age, gender, diagnosis, time from disease onset, and geographic location (urban vs rural).

METHODS

Data for patients with stroke or TBI that initiated the use of Constant Therapy, a remotely delivered, cloud-based rehabilitation program for patients with speech-language disorders, were retrospectively analyzed. Only data from therapeutic sessions completed at home were included. The following three activity metrics were evaluated: (1) the number of active weeks of therapy, (2) the average number of active therapy days per week, and (3) the total number of therapeutic sessions completed during the first 20 weeks of program access. An active day or week was defined as having at least one completed therapeutic session. Separate multiple linear regression models were performed with each activity measure as the dependent variable and all available patient demographics as model covariates.

RESULTS

Data for 2850 patients with stroke or TBI were analyzed, with the average patient completing 8.6 weeks of therapy at a frequency of 1.5 days per week. Contrary to known barriers to technological adoption, older patients were more active during their first 20 weeks of program access, with those aged 51 to 70 years completing 5.01 more sessions than patients aged 50 years or younger (P=.04). Similarly, patients living in a rural area, who face greater barriers to clinic access, were more digitally engaged than their urban counterparts, with rural patients completing 11.54 more (P=.001) sessions during their first 20 weeks of access, after controlling for other model covariates.

CONCLUSIONS

An evaluation of real-world data demonstrated that patients with stroke and TBI use digital therapy frequently for cognitive and language rehabilitation at home. Usage was higher in areas with limited access to clinical services and was unaffected by typical barriers to technological adoption, such as age. These findings will help guide the direction of future research in digital rehabilitation therapy, including the impact of demographics on recovery outcomes and the design of large, randomized controlled trials.

Self-managed, computerised speech and language therapy for patients with chronic aphasia post-stroke compared with usual care or attention control (Big CACTUS): a multicentre, single-blinded, randomised controlled trial

BACKGROUND

Post-stroke aphasia might improve over many years with speech and language therapy; however speech and language therapy is often less readily available beyond a few months after stroke. We assessed self-managed computerised speech and language therapy (CSLT) as a means of providing more therapy than patients can access through usual care alone.

METHODS

In this pragmatic, superiority, three-arm, individually randomised, single-blind, parallel group trial, patients were recruited from 21 speech and language therapy departments in the UK. Participants were aged 18 years or older and had been diagnosed with aphasia post-stroke at least 4 months before randomisation; they were excluded if they had another premorbid speech and language disorder caused by a neurological deficit other than stroke, required treatment in a language other than English, or if they were currently using computer-based word-finding speech therapy. Participants were randomly assigned (1:1:1) to either 6 months of usual care (usual care group), daily self-managed CSLT plus usual care (CSLT group), or attention control plus usual care (attention control group) with the use of computer-generated stratified blocked randomisation (randomly ordered blocks of sizes three and six, stratified by site and severity of word finding at baseline based on CAT Naming Objects test scores). Only the outcome assessors and trial statistician were masked to the treatment allocation. The speech and language therapists who were doing the outcome assessments were different from those informing participants about which group they were assigned to and from those delivering all interventions. The statistician responsible for generating the randomisation schedule was separate from those doing the analysis. Co-primary outcomes were the change in ability to retrieve personally relevant words in a picture naming test (with 10% mean difference in change considered a priori as clinically meaningful) and the change in functional communication ability measured by masked ratings of video-recorded conversations, with the use of Therapy Outcome Measures (TOMs), between baseline and 6 months after randomisation (with a standardised mean difference in change of 0·45 considered a priori as clinically meaningful). Primary analysis was based on the modified intention-to-treat (mITT) population, which included randomly assigned patients who gave informed consent and excluded those without 6-month outcome measures. Safety analysis included all participants. This trial has been completed and was registered with the ISRCTN, number ISRCTN68798818.

FINDINGS

From Oct 20, 2014, to Aug 18, 2016, 818 patients were assessed for eligibility, of which 278 (34%) participants were randomly assigned (101 [36%] to the usual care group; 97 [35%] to the CSLT group; 80 [29%] to the attention control group). 86 patients in the usual care group, 83 in the CSLT group, and 71 in the attention control group contributed to the mITT. Mean word finding improvements were 1·1% (SD 11·2) in the usual care group, 16·4% (15·3) in the CSLT group, and 2·4% (8·8) in the attention control group. Word finding improvement was 16·2% (95% CI 12·7 to 19·6; p<0·0001) higher in the CSLT group than in the usual care group and was 14·4% (10·8 to 18·1) higher than in the attention control group. Mean changes in TOMs were 0·05 (SD 0·59) in the usual care group (n=84), 0·04 (0·58) in the CSLT group (n=81), and 0·10 (0·61) in the attention control group (n=68); the mean difference in change between the CSLT and usual care groups was -0·03 (-0·21 to 0·14; p=0·709) and between the CSLT and attention control groups was -0·01 (-0·20 to 0·18). The incidence of serious adverse events per year were rare with 0·23 events in the usual care group, 0·11 in the CSLT group, and 0·16 in the attention control group. 40 (89%) of 45 serious adverse events were unrelated to trial activity and the remaining five (11%) of 45 serious adverse events were classified as unlikely to be related to trial activity.

INTERPRETATION

CSLT plus usual care resulted in a clinically significant improvement in personally relevant word finding but did not result in an improvement in conversation. Future studies should explore ways to generalise new vocabulary to conversation for patients with chronic aphasia post-stroke.

Effectiveness of rehabilitation training combined with acupuncture on aphasia after cerebral hemorrhage: A systematic review protocol of randomized controlled trial

BACKGROUND

This study aims to systematically evaluate the effectiveness of rehabilitation training (RT) combined with acupuncture on aphasia after cerebral hemorrhage (CH).

METHODS

PUBMED, Cochrane Central Register of Controlled Trials, EMBASE, Web of Science, Ovid, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure will be searched to identify any potential studies from inception to March 1, 2019, without language restrictions. All randomized controlled trials and case-controlled studies assessing the effectiveness of RT combined with acupuncture for the treatment of aphasia following CH will be included in this study. Cochrane risk of bias tool will be used to determine the methodological quality for included studies. RevMan 5.3 software (Cochrane Community, London, UK) will be utilized to perform statistical analysis.

RESULTS

This study will systematically evaluate the effectiveness of RT and acupuncture for aphasia post CH. Primary outcome includes aphasia, which can be measured by Aachener Aphasia Test or Communicative Activity Log or other related scales. Secondary outcomes consist of speech performance, as assessed by Western Aphasia Battery-Revised; measure of skill in Supported Conversation scales; measure of Participation in Conversation scales; types of strategies used in conversation; occurrence and repair of conversation breakdowns; as well as any adverse events.

CONCLUSION

The results of this study will provide present evidence on assessing effectiveness of RT and acupuncture after CH.

DISSEMINATION AND ETHICS

Comparison of Therapy Practice at Home and in the Clinic: A Retrospective Analysis of the Constant Therapy Platform Data Set

Background: Computer-based therapies can provide an affordable and practical alternative by providing frequent intervention for stroke survivors with chronic aphasia by allowing the opportunity for home exercise practice, however more evidence is needed. The goal of this retrospective analysis was to compare the time course of therapy engagement when therapy was targeted in the clinic or at home by post-stroke individuals. We examined if home users of the therapy were compliant in therapy and if this documented practice time was associated with improved outcomes similar to clinic patients who practiced under the guidance of a clinician. Methods: A retrospective analysis of anonymously aggregated data collected for 3,686 patients with post-stroke aphasia over the course of four years (2013-2017) was conducted. Participants either received therapy delivered through Constant Therapy only at home (N = 2,100) or only in the clinic (N = 1,577). Constant Therapy includes over 70 evidence-based therapies for language and cognitive skills. This program was individualized for each patient with targeted tasks that dynamically adapted to each individual's progress. Results: Patients with <60% accuracy were analyzed to determine how long it took them to reach >90% accuracy. Results showed that both home-therapy and clinic patients reached 90% accuracy on their tasks similarly (Median = 3 sessions), but the frequency of therapy was significantly different with 50% of home users receiving therapy at least every 2 days while 50% of clinic patients only had therapy once every 5 days (p < 0.001). Thus, home-therapy users were able to master tasks in a shorter time (median of 6 days) than clinic patients (median of 12 days) (p < 0.001). Conclusion: Outcomes of treatment are similar for home users and clinic patients indicating the potential usability of a home-based treatment program for rehabilitation for post-stroke aphasia.
