Delivering for aphasia

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.

From concept to practice: a scoping review of the application of AI to aphasia diagnosis and management

PURPOSE

Aphasia is an acquired communication disability resulting from impairments in language processing following brain injury, most commonly stroke. People with aphasia experience difficulties in all modalities of language that impact their quality of life. Therefore, researchers have investigated the use of Artificial Intelligence (AI) to deliver innovative solutions in Aphasia management and rehabilitation.

MATERIALS AND METHODS

We conducted a scoping review of the use of AI in aphasia research and rehabilitation to explore the evolution of AI applications to aphasia, the progression of technologies and applications. Furthermore, we aimed to identify gaps in the use of AI in Aphasia to highlight the potential areas where AI might add value. We analysed 77 studies to determine the research objectives, the history of AI techniques in Aphasia and their progression over time.

RESULTS

Most of the studies focus on automated assessment using AI, with recent studies focusing on AI for therapy and personalised assistive systems. Starting from prototypes and simulations, the use of AI has progressed to include supervised machine learning, unsupervised machine learning, natural language processing, fuzzy rules, and genetic programming.

CONCLUSION

Considerable scope remains to align AI technology with aphasia rehabilitation to empower patient-centred, customised rehabilitation and enhanced self-management.

Functional neuroimaging and behavioral correlates of multisite tDCS as an add-on to language training in a person with post-stroke non-fluent aphasia: a year-long case study

Mary, who experienced non-fluent aphasia as a result of an ischemic stroke, received 10 years of personalized language training (LT), resulting in transient enhancements in speech and comprehension. To enhance these effects, multisite transcranial Direct Current Stimulation (tDCS) was added to her LT regimen for 15 sessions. Assessment using the Reliable Change Index showed that this combination improved her left inferior frontal connectivity and speech production for two months and significantly improved comprehension after one month. The results indicate that using multisite transcranial direct current stimulation (tDCS) can improve the effectiveness of language therapy (LT) for individuals with non-fluent aphasia.

Knowns and unknowns about the neurobiology of stuttering

Stuttering occurs in early childhood during a dynamic phase of brain and behavioral development. The latest studies examining children at ages close to this critical developmental period have identified early brain alterations that are most likely linked to stuttering, while spontaneous recovery appears related to increased inter-area connectivity. By contrast, therapy-driven improvement in adults is associated with a functional reorganization within and beyond the speech network. The etiology of stuttering, however, remains enigmatic. This Unsolved Mystery highlights critical questions and points to neuroimaging findings that could inspire future research to uncover how genetics, interacting neural hierarchies, social context, and reward circuitry contribute to the many facets of stuttering.

The volume and the distribution of premorbid white matter hyperintensities: Impact on post-stroke aphasia

White matter hyperintensities (WMH) are a radiological manifestation of progressive white matter integrity loss. The total volume and distribution of WMH within the corpus callosum have been associated with pathological cognitive ageing processes but have not been considered in relation to post-stroke aphasia outcomes. We investigated the contribution of both the total volume of WMH, and the extent of WMH lesion load in the corpus callosum to the recovery of language after first-ever stroke. Behavioural and neuroimaging data from individuals (N = 37) with a left-hemisphere stroke were included at the early subacute stage of recovery. Spoken language comprehension and production abilities were assessed using word and sentence-level tasks. Neuroimaging data was used to derive stroke lesion variables (volume and lesion load to language critical regions) and WMH variables (WMH volume and lesion load to three callosal segments). WMH volume did not predict variance in language measures, when considered together with stroke lesion and demographic variables. However, WMH lesion load in the forceps minor segment of the corpus callosum explained variance in early subacute comprehension abilities (t = -2.59, p = .01) together with corrected stroke lesion volume and socio-demographic variables. Premorbid WMH lesions in the forceps minor were negatively associated with early subacute language comprehension after aphasic stroke. This negative impact of callosal WMH on language is consistent with converging evidence from pathological ageing suggesting that callosal WMH disrupt the neural networks supporting a range of cognitive functions.

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.

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.

The use of virtual reality in the rehabilitation of aphasia: a systematic review

PURPOSE

This systematic review explored how virtual reality (VR) has been used to rehabilitate aphasia.

MATERIALS AND METHODS

Empirical studies were included where VR was used to target language, well-being, or quality of life in adults with acquired language impairment. Degenerative communication disabilities were excluded. Seven health databases were searched in October 2021. Risk of Bias was assessed using published checklists and completeness of intervention reporting evaluated. Narrative synthesis described forms of VR, rationales given, outcome measures, communication functions targeted, characteristics of interventions, and outcomes achieved within the framework of impairment, activity, and participation.

RESULTS

Fourteen studies, involving 229 participants, met the criteria. The studies employed four forms of VR with various rationales given. Interventions used published and novel protocols. Primary outcomes targeted language impairment (12/14), activity (1/14), and well-being (1/14) and achieved positive outcomes in impairment and activity. All studies were exploratory. Risk of bias was high. Findings are discussed in the context of gains achieved by VR in other health contexts and the multi-user gaming literature.

CONCLUSIONS

Uses of VR in aphasia rehabilitation described in the literature are limited. Most applications target the remediation of language impairments. Opportunities to address activity, participation, and wider aspects of well-being are rare.IMPLICATIONS FOR REHABILITATIONResearch documenting the use of virtual reality (VR) to rehabilitate aphasia is limited and exploratory, so does not yet offer clear guidance for clinicians.Many of the identified studies have used known published protocols (e.g., naming therapy or scripts therapy) delivered through the novel VR format and focus on language impairment outcomes.VR offers clinicians a unique opportunity to address communication activity and participation through the use of multi-user virtual worlds, but this has only been explored by only two research teams.

People with aphasia share their views on self-management and the role of technology to support self-management of aphasia

PURPOSE

Self-management can lead to increased self-efficacy and improved quality of life for individuals with chronic conditions; however, there is little research exploring how self-management approaches can be used for chronic communication disorders, such as aphasia. Modifications to self-management approaches would be required to accommodate for aphasia; therefore, the input of people with aphasia (PwA) should be sought. The aims of the present study were: (1) To investigate and document the experiences and perspectives of PwA regarding self-management; (2) To explore how technology can be used to support aphasia self-management.

MATERIALS AND METHODS

In-depth, semi-structured interviews were conducted with 26 PwA living in Australia. Qualitative content analysis was used to analyse interview data.

RESULTS

Analysis resulted in six themes: (1) In self-management, PwA take control of life with aphasia and assume responsibility for engaging in opportunities to improve overall communication; (2) Community aphasia groups are important enablers of self-management because they facilitate peer support; (3) Communication partners (CPs) provide multifaceted support in aphasia self-management; (4) SLPs provide integrated support and coordination in aphasia self-management; (5) Technology supports PwA to self-manage speech therapy and communication in daily life; (6) Psychological and physical health issues and societal factors may impact aphasia self-management abilities.

CONCLUSION

From the perspective of PwA, aphasia self-management involves enhancing skills enabling communication and life participation. PwA are central to aphasia self-management, with support provided by CPs, peers, and SLPs. Technology has a range of applications in aphasia self-management. PwA identified potential personal and contextual barriers that may impact self-management.IMPLICATIONS FOR REHABILITATIONFor people with aphasia, engaging in conversation and social interaction are primary means of managing/improving communicative life participation; therefore, this should be a key focus of aphasia self-management programs.Aphasia self-management approaches should maximise the use of available support and provide tailored information, education, and training in the area of self-management to key stakeholders (people with aphasia, communication partners, and speech-language pathologists).People with aphasia should be supported to use technology for aphasia self-management, encompassing communication specific and daily life use.People with aphasia should be heavily involved in the development of structured aphasia self-management approaches.

The Incidence of Aphasia, Cognitive Deficits, Apraxia, Dysarthria, and Dysphagia in Acute Post Stroke Persian Speaking Adults

Stroke is a major cause of serious disabilities in adults. While communication deficits post stroke are prevalent and disabling, early detection of them is important during acute phase. There is limited data published on the incidence of communication disorders in Persian speaking adults following post stroke to our knowledge. The present study aims to determine the incidence and associated factors of aphasia, cognitive deficits, motor speech disorders (apraxia and dysarthria) as well as dysphagia following acute post stroke in Persian speaking adults. 100 stroke patients were assessed using P-WAB, MMSE, Oral Apraxia test, Informal Dysarthria assessment, and MASA. The data was collected from 2 hospitals in Tehran using convenient sampling for the duration of 1 year. Based on our findings, the incidence of aphasia, cognitive deficits, oral apraxia, dysarthria, and dysphagia was in respectively 61.8%, 76%, 30%, 61%, and 39% of stroke patients during the acute phase. Patients with aphasia were significantly older (mean age, 59.29 vs. 64.95), and had fewer education years (9.21 vs. 5.45) compared to individuals without aphasia (p < .05). Co-occurrence of aphasia and dysarthria, dysphasia, cognitive deficits, and apraxia was in respectively 40%, 31%, 55%, and 25%. Due to the high incidence of neurogenic communication disorders and dysphagia during the acute post stroke, especially in the elderly and the less educated patients, prompt and rapid detection of these deficits and rehabilitation is essential to ameliorate patients' quality of life and social participation, and reduce the comorbidities risk.

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.

Characteristics and impacts of community aphasia group facilitation: a systematic scoping review

PURPOSE

Community aphasia groups (CAGs) can provide a range of benefits to people with aphasia and support long-term psychosocial wellbeing. However, the dominant speech-pathologist-led service delivery model is inherently limited in scope. Peer-led groups hold potential as a sustainable and empowering extension of this traditional model. The implementation of peer-led models likely requires targeted training and support, however little is known about the characteristics and impacts of CAG facilitation. This study reviews the literature on CAGs and their facilitation.

MATERIALS AND METHODS

We conducted a scoping review on this topic.

RESULTS

One hundred and seventy-seven texts were included, reporting on a heterogeneous range of activities. Most texts reported on speech-pathologist-led groups, however, a range of alternative models were also represented. While no studies directly compared the impacts of different facilitation models, some comparative benefits could be drawn from the literature. Facilitation was perceived as complex and challenging, and significant gaps were identified in the training of facilitators. Ten qualitative studies investigated characteristics and impacts of facilitator behaviours, providing a useful foundation for future development of training and evaluation tools.

CONCLUSIONS

Further investigation into alternative facilitation models and facilitator training needs will likely support the proliferation of high-quality CAGs.Implications for RehabilitationCommunity aphasia groups (CAGs) play an important role in supporting identity and wellbeing for individuals with chronic aphasia.The traditional speech-pathology led model of group service delivery is limited in scope; the addition of peer- and volunteer-led CAGs may facilitate access to groups and meet a range of different needs for individuals with aphasia.CAG facilitation is a complex and challenging task, likely requiring specialised training, however, this has not been widely available to facilitators.The development of specialised facilitator training will likely support the proliferation of sustainable and high-quality CAGs.

Communication partner perspectives of aphasia self-management and the role of technology: an in-depth qualitative exploration

PURPOSE

"Self-management" empowers individuals to take responsibility for their healthcare through skill-building, personal growth, and self-efficacy related to chronic health condition management. Self-management approaches may benefit people with aphasia (PwA); however, PwA are often excluded from stroke self-management research and there is no published research reporting on aphasia-specific self-management programs. Communication partners (CPs) are involved in the rehabilitation and day-to-day lives of PwA, thus giving them unique insights and knowledge of PwA needs. The present study aimed to investigate CP experiences and perspectives regarding aphasia self-management and to explore CP perceptions of the use of technology in aphasia self-management.

METHODS

In-depth, semi-structured interviews with 14 CPs living in Australia. Interview data was analysed using qualitative content analysis.

RESULTS

Analysis revealed six core themes: (1) aphasia self-management is embedded into everyday life, (2) CPs provide comprehensive self-management support, (3) speech-language pathologists (SLPs) provide tools and support to enable PwA to self-manage, (4) aphasia self-management can be enhanced by technological supports, (5) potential positive outcomes of aphasia self-management, and (6) factors influencing successful aphasia self-management.

CONCLUSIONS

Aphasia self-management programs should focus on individual needs, functional communication in daily life, and social interaction. PwA and CPs are central to these programs, assisted by SLPs. Technology should be explored to augment aphasia self-management.Implications for RehabilitationCommunication partners suggest that people with aphasia are already engaging in aspects of self-management and that more formal aphasia-specific self-management approaches may be beneficial.Dedicated aphasia self-management programs should be situated in daily life with a focus on functional communication, life participation, confidence, and independence.Communication partners, speech-language pathologists, and technology are key support sources for aphasia self-management.Further input should be sought from communication partners in the development of aphasia self-management programs.

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.

Differential Effects of Speech and Language Therapy and rTMS in Chronic Versus Subacute Post-stroke Aphasia: Results of the NORTHSTAR-CA Trial

BACKGROUND & OBJECTIVE

Contralesional 1-Hz repetitive transcranial magnetic stimulation (rTMS) over the right pars triangularis combined with speech-language therapy (SLT) has shown positive results on the recovery of naming in subacute (5-45 days) post-stroke aphasia. NORTHSTAR-CA is an extension of the previously reported NORTHSTAR trial to chronic aphasia (>6 months post-stroke) designed to compare the effectiveness of the same rTMS protocol in both phases.

METHODS

Sixty-seven patients with left middle cerebral artery infarcts (28 chronic, 39 subacute) were recruited (01-2014 to 07-2019) and randomized to receive rTMS (N = 34) or sham stimulation (N = 33) with SLT for 10 days. Primary outcome variables were Z-score changes in naming, semantic fluency and comprehension tests and adverse event frequency. Intention-to-treat analyses tested between-group effects at days 1 and 30 post-treatment. Chronic and subacute results were compared.

RESULTS

Adverse events were rare, mild, and did not differ between groups. Language outcomes improved significantly in all groups irrespective of treatment and recovery phase. At 30-day follow-up, there was a significant interaction of stimulation and recovery phase on naming recovery (P <.001). Naming recovery with rTMS was larger in subacute (Mdn = 1.91/IQR = .77) than chronic patients (Mdn = .15/IQR = 1.68/P = .015). There was no significant rTMS effect in the chronic aphasia group.

CONCLUSIONS

The addition of rTMS to SLT led to significant supplemental gains in naming recovery in the subacute phase only. While this needs confirmation in larger studies, our results clarify neuromodulatory vs training-induced effects and indicate a possible window of opportunity for contralesional inhibitory stimulation interventions in post-stroke aphasia.

Guideline adherence in speech and language therapy in stroke aftercare. A health insurance claims data analysis

Background

Impairments to comprehension and production of speech (aphasia, dysarthria) and swallowing disorders (dysphagia) are common sequelae of stroke, reducing patients’ quality of life and social participation. Treatment oriented on evidence-based guidelines seems likely to improve outcomes. Currently, little is known about guideline adherence in stroke aftercare for the above-mentioned sequelae. This study aims to analyse guideline adherence in the treatment of aphasia, dysarthria and dysphagia after stroke, based on suitable test parameters, and to determine factors that influence the implementation of recommended therapies.

Methods

Six test parameters were defined, based on systematic study of guidelines for the treatment of speech impairments and swallowing disorders (e.g. comprehensive diagnostics, early initiation and continuity). Guideline adherence in treatment was tested using claims data from four statutory health insurance companies. Multivariate logistic and linear regression analyses were performed in order to test the outcomes.

Results

4,486 stroke patients who were diagnosed with specific disorders or received speech therapy were included in the study. The median age was 78 years; the proportion of women was 55.9%. Within the first year after the stroke, 90.3% of patients were diagnosed with speech impairments and swallowing disorders. Overall, 44.1% of patients received outpatient speech and language therapy aftercare. Women were less frequently diagnosed with specific disorders (OR 0.70 [95%CI:0.55/0.88], p = 0.003) and less frequently received longer therapy sessions (OR 0.64 [95%CI:0.43/0.94], p = 0.022). Older age and longer hospitalization duration increased the likelihood of guideline recommendations being implemented and of earlier initiation of stroke aftercare measures.

Conclusions

Our observations indicate deficits in the implementation of guideline recommendations in stroke aftercare. At the same time, they underscore the need for regular monitoring of implementation measures in stroke aftercare to address group-based disparities in care.

Cognitive and Linguistic Benefits of Aerobic Exercise: A State-of-the-Art Systematic Review of the Stroke Literature

This systematic review aimed to determine how aerobic exercise affects cognition after stroke, with particular focus on aphasia and language improvement. Methodological quality was assessed with the PEDro+ scale with half of the 27 included studies rated as high quality. Data extraction focused on cognitive effects of aerobic exercise post-stroke, intervention characteristics, outcome measures, and participant characteristics. Whereas attention, memory, and executive functioning measures were common across the included studies, no study included a language-specific, performance-based measure. Seventeen studies reported positive cognitive effects, most frequently in the domains of attention, memory and executive functioning. Variability in outcome measures, intervention characteristics, and participant characteristics made it difficult to identify similarities among studies reporting positive cognitive effects of exercise or among those studies reporting null outcomes. Only three studies provided specific information about the number of individuals with aphasia included or excluded, who comprise approximately one-third of the stroke population. The review identified patent gaps in our understanding of how aerobic exercise may affect not only the cognitive domain of language post-stroke but also the broader cognitive functioning of individuals with post-stroke aphasia. Methodological limitations of the reviewed studies also warrant further examination of the direct impact of aerobic exercise on cognition post-stroke with careful attention to the selection and reporting of population, intervention, and outcomes.

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.

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.

Long-Term Stability of Short-Term Intensive Language-Action Therapy in Chronic Aphasia: A 1-2 year Follow-Up Study

Background. Intensive aphasia therapy can improve language functions in chronic aphasia over a short therapy interval of 2-4 weeks. For one intensive method, intensive language-action therapy, beneficial effects are well documented by a range of randomized controlled trials. However, it is unclear to date whether therapy-related improvements are maintained over years. Objective. The current study aimed at investigating long-term stability of ILAT treatment effects over circa 1-2 years (8-30 months). Methods. 38 patients with chronic aphasia participated in ILAT and were re-assessed at a follow-up assessment 8-30 months after treatment, which had been delivered 6-12.5 hours per week for 2-4 weeks. Results. A standardized clinical aphasia battery, the Aachen Aphasia Test, revealed significant improvements with ILAT that were maintained for up to 2.5 years. Improvements were relatively better preserved in comparatively young patients (<60 years). Measures of communicative efficacy confirmed improvements during intensive therapy but showed inconsistent long-term stability effects. Conclusions. The present data indicate that gains resulting from intensive speech-language therapy with ILAT are maintained up to 2.5 years after the end of treatment. We discuss this novel finding in light of a possible move from sparse to intensive therapy regimes in clinical practice.

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).

Factors predicting long-term recovery from post-stroke aphasia

BACKGROUND

It remains widely accepted that spontaneous recovery from aphasia is largely limited to the first related factors. This has direct implications for acute and chronic interventions for aphasia. few months following stroke. A few recent studies challenge this view, revealing that some individuals' language abilities improve even during the chronic stage.

AIMS

To identify prognostic indicators of long-term aphasia recovery.

METHODS & PROCEDURES

Eighteen people with aphasia initially evaluated in the chronic stage were retested at least one year later. The Western Aphasia Battery-Revised (WAB-R) Aphasia Quotient (AQ) was used to quantify changes in language impairment. Prognostic factors included those related to the patient (demographic, psychosocial), stroke (lesion volume and location), and treatment (medical, rehabilitative).

OUTCOMES & RESULTS

Twelve participants improved and 6 remained stable or declined. Linear regression analysis revealed that lesion volume predicted long-term language gains, with smaller lesions yielding greater improvements. Individuals who did not improve were more likely to have lesions encompassing critical frontal and temporoparietal cortical regions and interconnecting white matter pathways. Exploratory regression analysis of psychosocial and treatment-related factors revealed a positive relationship between improvement and satisfaction with life participation, and a negative relationship between improvement and perceived impairment severity. Critically, psychosocial and treatment-related factors significantly improved model fit over lesion volume, suggesting that these factors add predictive value to determining long-term aphasia prognosis.

CONCLUSIONS

Long-term aphasia recovery is multidetermined by a combination of stroke-, psychosocial-, and treatment-related factors. This has direct implications for acute and chronic interventions for aphasia.

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.

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.

Technical Features, Feasibility, and Acceptability of Augmented Telerehabilitation in Post-stroke Aphasia-Experiences From a Randomized Controlled Trial

Background: Post-stroke aphasia is a communication disorder where existing evidence favors intensive therapy methods. Telerehabilitation represents a service model for geographically remote settings, or other barriers to clinic attendance or to facilitate an augmentation of therapy across a continuum of care. Evidence to support efficiency, feasibility, and acceptability is however still scarce. Appraising aphasia telerehabilitation in controlled trials beyond its effectiveness, by investigating feasibility and acceptability, may facilitate implementation into clinical practice. Methods: In our pilot randomized controlled trial, we investigated the feasibility and acceptability of speech and language therapy by videoconference, in addition to usual care, in people with aphasia following stroke. To improve functional, expressive language, a tailored intervention was given 1 h per day, five times per week over four consecutive weeks. Feasibility measures included evaluation of technical setup using diary logs. Acceptability was investigated by examining adherence and satisfaction with therapy alongside evaluation of data safety and privacy. Results: Feasibility and acceptability data were collected in relation to 556.5 h of telerehabilitation delivered to 30 participants over a 2-years intervention period by three speech-language pathologists. Protocol adherence was high, with a tolerable technical fault rate; 86 faults were registered over 541 video sessions. Most (80%; n = 30) of the participants experienced zero to three faults. The main cause of technical failures was flawed internet connection, causing delayed or interrupted therapy. Total satisfaction with telerehabilitation was rated good or very good by 93.1% (n = 29) of participants and two of three speech-language pathologists. Within a moderate variance of technical failure, participants experiencing more faults were more satisfied. No serious events regarding security and privacy were reported. Our model is feasibly and ready to be implemented across a range of clinical settings and contexts. Conclusions: Synchronous telerehabilitation for post-stroke aphasia is feasible and acceptable and shows tolerable technical fault rates with high satisfaction among patients and pathologists. Within a low rate of faults, satisfaction was not negatively influenced by fault frequency. Access to clinical and technical expertise is needed when developing telerehabilitation services. Telerehabilitation may be a viable service delivery model for aphasia rehabilitation. Trial Registration: ClinicalTrials.gov, ID: NCT02768922.

Non-invasive brain stimulation as add-on therapy for subacute post-stroke aphasia: a randomized trial (NORTHSTAR)

Introduction

Non-invasive brain stimulation (NIBS) with speech therapy might improve recovery from post-stroke aphasia. This three-armed sham-controlled blinded prospective proof-of-concept study tested 1 Hz subthreshold repetitive transcranial magnetic stimulation (rTMS) and 2-mA cathodal transcranial direct current stimulation (ctDCS) on the right pars triangularis in subacute post-stroke aphasia.

Patients and methods

Sixty-three patients with left middle cerebral artery infarcts were recruited in five hospitals (Canada/United States/Germany, 01-2014/03-2018) and randomized to receive rTMS (N = 20), ctDCS (N = 24) or sham stimulation (N = 19) with ST for 10 days. Primary outcome variables were Z-score changes in naming, semantic fluency and comprehension tests and adverse event frequency. Secondary outcome variable was the percent change in the Unified Aphasia Score. Intention-to-treat analyses tested between-group effects at days 1 and 30 post-treatment with a pre-planned subgroup analysis for lesion location (affecting Broca's area or not).

Results

Naming was significantly improved by rTMS (median = 1.91/interquartile range = 0.77/p = .01) at 30 days versus ctDCS (median = 1.11/interquartile range = 1.51) and sham stimulation (median = 1.02/interquartile range = 1.71). All other primary results were non-significant. The rTMS effect was driven by the patient subgroup with intact Broca's area where NIBS tended to improve UnAS (median = 33.2%/interquartile range = 46.7%/p = .062) versus sham stimulation (median = 12.5%/interquartile range = 7.9%) at day 30. Conversely, in patients with infarcted Broca's area, UnAS tended to improve more with sham stimulation (median = 75.0%/interquartile range = 86.9%/p = .053) versus NIBS (median = 12.7%/interquartile range = 31.7).Conclusion: We found a delayed positive effect of low-frequency rTMS targeting the right pars triangularis on the recovery of naming performance in subacute post-stroke aphasia. This intervention may be beneficial only in patients with morphologically intact Broca's area.

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.

Revisiting the public awareness of aphasia in Exeter: 16 years on

Background: Surveys of awareness of aphasia have been conducted worldwide. There has been no survey of change in awareness in one place over time. A survey in Exeter, UK in 2001 found awareness of aphasia was strikingly low. The aim of this study was to conduct a repeat survey using the same methods in the same city 16 years later to examine changes in awareness and knowledge. Method: We surveyed 167 shoppers in Exeter examining awareness and knowledge of aphasia. Awareness of stroke, stuttering, dyslexia and autism were examined for comparison. Demographic information was collected. Result: Thirty-four percent had heard of aphasia and 5% had some basic knowledge. Awareness of aphasia had improved significantly from 2001 to 2017, but basic knowledge had not. Awareness was higher in professional groups, such as lawyers and academics, and healthcare workers and in those who knew someone with aphasia. Awareness, but not knowledge, was higher in older respondents. Awareness of aphasia was significantly lower than awareness of all other conditions. Conclusion: We found a significant increase in awareness of aphasia in Exeter since 2001, but not knowledge. The implications of ongoing low levels of aphasia awareness, like inadequate funding and difficulty integrating into an ill-informed society, are discussed.

Self-reported feedback in ICT-delivered aphasia rehabilitation: a literature review

PURPOSE

Information and Communication Technologies (ICT) can provide an option for the delivery of intensive aphasia rehabilitation but the users' views (i.e., People with Aphasia) must be considered to ensure satisfaction, motivation and adherence with this mode of rehabilitation. The aim of this literature review is to provide a critical overview of studies where feedback was elicited from participants about their experiences with ICT-delivered aphasia rehabilitation.

METHODS

A systematic search using six electronic databases was conducted in July 2015 and updated in May 2019. Studies of synchronous telerehabilitation and interventions targeting compensatory strategies were excluded from the review. Studies retrieved were screened for eligibility and information was extracted on the characteristics of each study, methods of data collection and study outcomes.

RESULTS

Seventeen studies met the inclusion criteria including studies with quantitative, qualitative and mixed-methods research designs. The studies employed a variety of data collection methods, examining a number of ICT-delivered aphasia rehabilitation activities and the findings investigated aspects of feasibility, usability and acceptance of this mode of rehabilitation.

CONCLUSIONS

The findings indicate ICT-delivered aphasia rehabilitation is considered an acceptable mode of rehabilitation by people with aphasia who reported generally positive feedback, though variation among personal perspectives and experience is noted. There is currently no consensus measure of self-reported feedback in ICT-delivered aphasia rehabilitation.IMPLICATIONS FOR REHABILITATIONICT-delivered aphasia rehabilitation may provide an acceptable mode of rehabilitation for people with aphasia.Exploring self-reported feedback from people with aphasia engaging in ICT-delivered aphasia rehabilitation will provide insights into their experiences of this mode of rehabilitation.This information may help to guide clinicians when collaboratively planning and monitoring ICT-delivered aphasia rehabilitation.Currently there is no consensus measure of self-reported feedback for people with aphasia engaging in ICT-delivered aphasia rehabilitation.

Technology-enhanced writing therapy for people with aphasia: results of a quasi-randomized waitlist controlled study

BACKGROUND

Acquired writing impairment, or dysgraphia, is common in aphasia. It affects both handwriting and typing, and may recover less well than other aphasic symptoms. Dysgraphia is an increasing priority for intervention, particularly for those wishing to participate in online written communication. Effective dysgraphia treatment studies have been reported, but many did not target, or did not achieve, improvements in functional writing. Functional outcomes might be promoted by therapies that exploit digital technologies, such as voice recognition and word prediction software.

AIMS

This study evaluated the benefits of technology-enhanced writing therapy for people with acquired dysgraphia. It aimed to explore the impact of therapy on a functional writing activity, and to examine whether treatment remediated or compensated for the writing impairment. The primary question was: Does therapy improve performance on a functional assessment of writing; and, if so, do gains occur only when writing is assisted by technology? Secondary measures examined whether therapy improved unassisted written naming, functional communication, mood and quality of life.

METHODS & PROCEDURES

The study employed a quasi-randomized waitlist controlled design. A total of 21 people with dysgraphia received 12 h of writing therapy either immediately or after a 6-week delay. The primary outcome measure was a functional assessment of writing, which was administered in handwriting and on a computer with assistive technology enabled. Secondary measures were: The Boston Naming Test (written version), Communication Activities of Daily Living-2, Visual Analogue Mood Scales (Sad question), and the Assessment of Living with Aphasia. Analyses of variance (ANOVA) were used to examine change on the outcome measures over two time points, between which the immediate group had received therapy but the delayed group had not. Pre-therapy, post-therapy and follow-up scores on the measures were also examined for all participants.

OUTCOMES & RESULTS

Time × group interactions in the ANOVA analyses showed that therapy improved performance on the functional writing assessment. Further interactions with condition showed that gains occurred only when writing was assisted by technology. There were no significant interactions in the analyses of the secondary outcome measures. A treatment effect on these measures was therefore unconfirmed.

CONCLUSIONS & IMPLICATIONS

This study showed that 21 people with dysgraphia improved on a functional writing measure following therapy using assistive technology. The results suggest that treatment compensated for, rather than remediated, the impairment, given that unassisted writing did not change. Further studies of technology-enhanced writing therapy are warranted.

Further Evidence of the Positive Influence of Repetitive Transcranial Magnetic Stimulation on Speech and Language in Patients with Aphasia after Stroke: Results from a Double-Blind Intervention with Sham Condition

BACKGROUND

After a stroke, up to 20% of patients suffer from aphasia. The preferred treatment for stroke-related aphasia (SRA) is regular speech and language training (SLT). In the present study, we investigated to what extent adjuvant repetitive transcranial magnetic stimulation (rTMS) might enhance recovery. While there is growing evidence of the positive effect of adjuvant rTMS on aphasia, no study has yet been based on an Iranian sample.

METHOD

A total of 12 patients (mean age: 55 years; right-handed; 7 women) underwent treatment for SRA 1 month after stroke. The standard treatment consisted of regular 45-min SLT sessions 5 times a week for 2 consecutive weeks. Additionally, patients were randomly assigned either to adjuvant rTMS (5 times a week for 30 min) or to a sham condition (5 times a week for 30 min). At baseline and after 2 weeks of intervention, the degree of aphasia was assessed with the Farsi version of the Western Aphasia Battery. rTMS was applied to the inferior posterior frontal gyrus of the right hemisphere.

RESULTS

Speech and language improved over time, but more so in the rTMS than in the sham condition. Large effect sizes were observed for content, fluency, and the aphasia quotient; medium effect sizes were observed for command comprehension and repetition, while effect sizes were small for auditory comprehension and naming.

CONCLUSIONS

Among patients with SRA, compared to a sham condition, adjuvant rTMS improved speech and language skills. The present results add to the accumulating evidence that rTMS as a neuromodulation technique has the capacity to enhance the effect of conventional SLT.

An International Survey of Assessment Practices for Short-Term and Working Memory Deficits in Aphasia

PURPOSE

Recent research has highlighted the clinical relevance of understanding the nature of short-term memory (STM) and working memory (WM) deficits in persons with aphasia and the way these deficits affect linguistic processing and functional communication in activities of daily living. The psychometric properties of tests commonly used to identify STM/WM problems in individuals with aphasia, however, have been questioned. No previous study has sought to investigate assessment practices and attitudes by speech-language pathologists involved in aphasia management. Accordingly, the aims of this study were (a) to investigate both attitudes toward STM/WM assessment in individuals with aphasia, as well as the types and frequency of STM/WM tests used with individuals with aphasia, and (b) to explore factors (e.g., educational background) that may influence STM/WM assessment practices.

METHOD

Respondents recruited via professional and aphasia support organizations completed an online survey. The survey elicited information about the respondents' demographic and clinical backgrounds and STM/WM assessment clinical practices and views, including frequency and preferred use of specific STM/WM tests.

RESULTS

The majority of respondents reported regular use of STM/WM tests as part of aphasia management. Positive attitudes toward STM/WM assessments were also reported. The most popular rankings of tests were the Cognitive Linguistic Quick Test (Helm-Estabrooks, 2001), the Comprehensive Aphasia Test (Swinburn, Porter, & Howard, 2005), and the Token Test (McNeil & Prescott, 1978). Results suggested limited knowledge about measures that assess self-perceptions of functional memory abilities. Regression analyses showed that the frequency of reported STM/WM test use was similar between clinicians and dual-role researchers/clinicians, but their attitudes toward the value of STM/WM differed. U.S. and UK respondents reported similar assessment practices.

CONCLUSIONS

It is reassuring that STM/WM is taken into consideration by clinicians when providing aphasia management. Two of the most popular tests, however, have poor psychometric properties, and caution should be exercised in clinical decision making. The different value placed on STM/WM testing by clinicians and researchers/clinicians has implications for continuing professional development.

tDCS over the motor cortex improves lexical retrieval of action words in poststroke aphasia

One-third of stroke survivors worldwide suffer from aphasia. Speech and language therapy (SLT) is considered effective in treating aphasia, but because of time constraints, improvements are often limited. Noninvasive brain stimulation is a promising adjuvant strategy to facilitate SLT. However, stroke might render “classical” language regions ineffective as stimulation sites. Recent work showed the effectiveness of motor cortex stimulation together with intensive naming therapy to improve outcomes in aphasia (Meinzer et al. 2016). Although that study highlights the involvement of the motor cortex, the functional aspects by which it influences language remain unclear. In the present study, we focus on the role of motor cortex in language, investigating its functional involvement in access to specific lexico-semantic (object vs. action relatedness) information in poststroke aphasia. To this end, we tested effects of anodal transcranial direct current stimulation (tDCS) to the left motor cortex on lexical retrieval in 16 patients with poststroke aphasia in a sham-controlled, double-blind study design. Critical stimuli were action and object words, and pseudowords. Participants performed a lexical decision task, deciding whether stimuli were words or pseudowords. Anodal tDCS improved accuracy in lexical decision, especially for words with action-related content and for pseudowords with an “action-like” ending ( t15 = 2.65, P = 0.036), but not for words with object-related content and pseudowords with “object-like” characteristics. We show as a proof-of-principle that the motor cortex may play a specific role in access to lexico-semantic content. Thus motor-cortex stimulation may strengthen content-specific word-to-semantic concept associations during language treatment in poststroke aphasia.

NEW & NOTEWORTHY The role of motor cortex (MC) in language processing has been debated in both health and disease. Recent work has suggested that MC stimulation together with speech and language therapy enhances outcomes in aphasia. We show that MC stimulation has a differential effect on object- and action-word processing in poststroke aphasia. We propose that MC stimulation may specifically strengthen word-to-semantic concept association in aphasia. Our results potentially provide a way to tailor therapies for language rehabilitation.

Collaboration, trouble and repair in multiparty interactions involving couples with dementia or aphasia

PURPOSE

The aim of the present study was to identify problems with communication with persons with aphasia and persons with dementia in a collaborative interview setting with their significant others. In particular, to compare interactional practices used in order to resolve problems caused by specific symptoms.

METHOD

Five persons with aphasia and five persons with dementia and their spouses participated in the study. Interviews were carried out couple by couple, and the interviews had a task-oriented character. The interviews were video and audio recorded. All interviews were transcribed. From the transcriptions categorisations according to previous literature were made.

RESULT

The results demonstrated that repair sequences were frequent in interaction involving people with aphasia (PWA), and even more so in interaction involving persons with dementia (PWD). In general, it was the PWA/PWD that initiated the repair sequence more often than the spouse, thus keeping the general rule of a preference for self-initiated repair compared to other-initiated repair.

CONCLUSION

The active involvement of the conversational partners in trouble solving sequences in interaction with PWA/PWD demonstrated in the present study indicates that the interactional style of the conversational partner to PWA/PWD important. This implies that conversation partner training programmes would be useful both for PWA and for PWD.

Cognitive performance in aphasia due to stroke: a systematic review

Aphasia persists in about one third of the patients with left hemisphere stroke, yet it is not known if it enhances the risk of dementia, beyond what results from any focal brain lesion. This lack of knowledge is mostly related to the difficulty of cognitive evaluation in people with aphasia. The development of tools aiming to assess cognitive functioning in people with aphasia could overcome this limitation. The aim of this systematic review was to evaluate the frequency and the profile of cognitive impairment in stroke patients with aphasia, to assemble existing non-verbal instruments to be used in patients with language disorders.

We conducted a systematic review, through Web of Science, Medline and PsycINFO electronic databases, of articles published between January 1995 and October 31, 2015 related to aphasia due to stroke and non-verbal neurobehavioral tests.

The electronic search identified 2487 citations. After screening 38 were included in this review. Additionally 53 articles were selected among the references of analyzed publications of which nine were included producing a total of 47 articles. The cognitive tests more frequently used in persons with aphasia are the Figures Memory Tests, Visual Memory Span, Progressive Matrices, Wisconsin Card Sorting Test and some measures of the Test of Everyday Attention, covering a reasonable range of cognitive domains. The majority of studies across cognitive domains reported lower scores for patients with aphasia compared with controls. No specific difficulties were reported regarding tests applicability.

There are several tools available to assess cognitive functions in aphasia. Although there is some variability, patients with aphasia tend to present lower scores than those with left hemisphere stroke without aphasia or healthy subjects. A consensus tool should be developed to screen or evaluate cognition and dementia in individuals with language impairment.

Evidence-based guidelines on the therapeutic use of transcranial direct current stimulation (tDCS)

A group of European experts was commissioned by the European Chapter of the International Federation of Clinical Neurophysiology to gather knowledge about the state of the art of the therapeutic use of transcranial direct current stimulation (tDCS) from studies published up until September 2016, regarding pain, Parkinson's disease, other movement disorders, motor stroke, poststroke aphasia, multiple sclerosis, epilepsy, consciousness disorders, Alzheimer's disease, tinnitus, depression, schizophrenia, and craving/addiction. The evidence-based analysis included only studies based on repeated tDCS sessions with sham tDCS control procedure; 25 patients or more having received active treatment was required for Class I, while a lower number of 10-24 patients was accepted for Class II studies. Current evidence does not allow making any recommendation of Level A (definite efficacy) for any indication. Level B recommendation (probable efficacy) is proposed for: (i) anodal tDCS of the left primary motor cortex (M1) (with right orbitofrontal cathode) in fibromyalgia; (ii) anodal tDCS of the left dorsolateral prefrontal cortex (DLPFC) (with right orbitofrontal cathode) in major depressive episode without drug resistance; (iii) anodal tDCS of the right DLPFC (with left DLPFC cathode) in addiction/craving. Level C recommendation (possible efficacy) is proposed for anodal tDCS of the left M1 (or contralateral to pain side, with right orbitofrontal cathode) in chronic lower limb neuropathic pain secondary to spinal cord lesion. Conversely, Level B recommendation (probable inefficacy) is conferred on the absence of clinical effects of: (i) anodal tDCS of the left temporal cortex (with right orbitofrontal cathode) in tinnitus; (ii) anodal tDCS of the left DLPFC (with right orbitofrontal cathode) in drug-resistant major depressive episode. It remains to be clarified whether the probable or possible therapeutic effects of tDCS are clinically meaningful and how to optimally perform tDCS in a therapeutic setting. In addition, the easy management and low cost of tDCS devices allow at home use by the patient, but this might raise ethical and legal concerns with regard to potential misuse or overuse. We must be careful to avoid inappropriate applications of this technique by ensuring rigorous training of the professionals and education of the patients.

Speech and language therapy for aphasia following subacute stroke

The aim of this study was to investigate the time window, duration and intensity of optimal speech and language therapy applied to aphasic patients with subacute stroke in our hospital. The study consisted of 33 patients being hospitalized for stroke rehabilitation in our hospital with first stroke but without previous history of speech and language therapy. Sixteen sessions of impairment-based speech and language therapy were applied to the patients, 30-60 minutes per day, 2 days a week, for 8 successive weeks. Aphasia assessment in stroke patients was performed with Gülhane Aphasia Test-2 before and after treatment. Compared with before treatment, fluency of speech, listening comprehension, reading comprehension, oral motor evaluation, automatic speech, repetition and naming were improved after treatment. This suggests that 16 seesions of speech and language therapy, 30-60 minutes per day, 2 days a week, for 8 successive weeks, are effective in the treatment of aphasic patients with subacute stroke.

Feature rich, but user-friendly: Speech pathologists' preferences for computer-based aphasia therapy

PURPOSE

High-intensity language therapy has been shown to provide greater outcomes for people with aphasia (PWA). Unfortunately, a number of issues including the ageing population and a lack of rurally-based clinicians prevent high-intensity interventions. Computer-based therapies are a potential solution to the issues of intensity and accessibility; however, this service delivery model is not commonly used. A possible reason behind the poor uptake is that current computer-based aphasia therapy (CBAT) programs may not meet the needs of speech-language pathologists (SLPs). This study investigated the preferences of SLPs with regard to the features desired in their ideal CBAT program.

METHOD

Phenomenological research methodology was used to explore the preferences of 10 SLPs. Data were analysed using qualitative thematic analysis.

RESULT

Desired features were grouped into five themes: therapy activities, stimuli, cues, access and progress data. A range of sub-themes were also identified.

CONCLUSION

The wide range of desirable features found in this study may reflect the extent to which current CBAT programs are considered to be useful, but perhaps do not meet the needs of users. The study's findings provide useful information for future CBAT developers to create programs with high clinician usability.

Piracetam for Aphasia in Post-stroke Patients: A Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Aphasia is a common symptom in post-stroke patients. Piracetam is a commonly used nootropic agent that promises various benefits to brain function, including language improvement.

OBJECTIVE

We performed a systematic review and meta-analysis to assess whether piracetam facilitates the rehabilitation of language performance in post-stroke patients.

METHODS

Randomized controlled trials (RCTs) of piracetam treatment in post-stroke patients published in any language were included, excluding those involving pre-existing cognitive disorders such as dementia and mood disturbances. We searched several databases including PubMed, EMBASE, Cochrane Central, CINAHL, Web of Science, and PsycINFO for RCTs published up to 31 December 2015. We conducted a meta-analysis using RevMan (version 5.3), with standardized mean differences (SMDs) and fixed-effect models, and used StataSE (version 13) for the detection of publication bias. This study has been submitted to PROSPERO, and its registration number is CRD42016034088.

RESULTS

We identified 1180 titles and abstracts, and finally included seven RCTs in this meta-analysis. The number of participants in each study ranged from 19 to 66, summing up to 261 patients overall. The dose of piracetam was consistent while the frequency and time of therapy varied. The assessment of the language at the end of trials showed no significant improvement in overall severity of aphasia [SMD 0.23, 95 % confidence interval (CI) -0.03 to 0.49, P = 0.08], but written language (SMD 0.35, 95 % CI 0.04 to 0.66, P = 0.03) showed pronounced improvement. Subgroup analyses indicated a dissociation of effectiveness between short- and long-term assessment in overall severity (P = 0.008, I (2) = 85.6 %) in terms of tests for subgroup differences, and a mild trend toward dissociation in written subtests (P = 0.30, I (2) = 5.1 %). Funnel plots and Egger's test identified no obvious publication bias in the primary variable.

CONCLUSIONS

Piracetam plays a limited role in the rehabilitation of overall language impairment and only benefits written language ability at the end of trials. Its effect on overall linguistic level and written language tends to emerge within a short period and declines thereafter.

Evaluation of an Expert System for the Generation of Speech and Language Therapy Plans

BACKGROUND

Speech and language pathologists (SLPs) deal with a wide spectrum of disorders, arising from many different conditions, that affect voice, speech, language, and swallowing capabilities in different ways. Therefore, the outcomes of Speech and Language Therapy (SLT) are highly dependent on the accurate, consistent, and complete design of personalized therapy plans. However, SLPs often have very limited time to work with their patients and to browse the large (and growing) catalogue of activities and specific exercises that can be put into therapy plans. As a consequence, many plans are suboptimal and fail to address the specific needs of each patient.

OBJECTIVE

We aimed to evaluate an expert system that automatically generates plans for speech and language therapy, containing semiannual activities in the five areas of hearing, oral structure and function, linguistic formulation, expressive language and articulation, and receptive language. The goal was to assess whether the expert system speeds up the SLPs' work and leads to more accurate, consistent, and complete therapy plans for their patients.

METHODS

We examined the evaluation results of the SPELTA expert system in supporting the decision making of 4 SLPs treating children in three special education institutions in Ecuador. The expert system was first trained with data from 117 cases, including medical data; diagnosis for voice, speech, language and swallowing capabilities; and therapy plans created manually by the SLPs. It was then used to automatically generate new therapy plans for 13 new patients. The SLPs were finally asked to evaluate the accuracy, consistency, and completeness of those plans. A four-fold cross-validation experiment was also run on the original corpus of 117 cases in order to assess the significance of the results.

RESULTS

The evaluation showed that 87% of the outputs provided by the SPELTA expert system were considered valid therapy plans for the different areas. The SLPs rated the overall accuracy, consistency, and completeness of the proposed activities with 4.65, 4.6, and 4.6 points (to a maximum of 5), respectively. The ratings for the subplans generated for the areas of hearing, oral structure and function, and linguistic formulation were nearly perfect, whereas the subplans for expressive language and articulation and for receptive language failed to deal properly with some of the subject cases. Overall, the SLPs indicated that over 90% of the subplans generated automatically were "better than" or "as good as" what the SLPs would have created manually if given the average time they can devote to the task. The cross-validation experiment yielded very similar results.

CONCLUSIONS

The results show that the SPELTA expert system provides valuable input for SLPs to design proper therapy plans for their patients, in a shorter time and considering a larger set of activities than proceeding manually. The algorithms worked well even in the presence of a sparse corpus, and the evidence suggests that the system will become more reliable as it is trained with more subjects.

Experiences of participation in goal setting for people with stroke-induced aphasia in Norway. A qualitative study

PURPOSE

The body of research into client participation in aphasia rehabilitation is increasing, but the evidence on how it is implemented into clinical practice is still scarce. Particularly, the importance of including the "insider's perspective" has been demanded. The aim of this study was to explore how people with aphasia experienced client participation during the process of goal setting and clinical decision making in language rehabilitation.

METHODS

Fifteen people with stroke-induced aphasia participated in semi-structured in-depth interviews. A qualitative analysis using Systematic Text Condensation was undertaken.

RESULTS

Analysis revealed four main themes: (1) pleased with services, (2) vagueness in language rehabilitation, (3) personal goals exist, and (4) desired level of participation.

CONCLUSION

Even though people with stroke-induced aphasia overall are pleased with the language rehabilitation, there is a need for greater emphasis on making the framework of language rehabilitation less vague. Therapists should also spend more time on collaboration with people with stroke-induced aphasia and use available methods to support communication and collaboration. The findings underscore the need for further exploration of the potential outcomes of implementing client participation in goal setting and clinical decision making for persons with stroke-induced aphasia. Implications for rehabilitation All persons with stroke induced aphasia should be asked about their goals for rehabilitation not only once, but during the whole continuum of their rehabilitation journey. Rehabilitation professionals should place greater emphasis on client participation by asking people with stroke induced aphasia how they prefer to participate at different stages of rehabilitation. To ensure active participation for those who wants it, existing tools and techniques which promoted collaborative goal setting should be better incorporated.

Improved language in chronic aphasia after self-delivered iPad speech therapy

Self-delivered speech therapy provides an opportunity for individualised dosage as a complement to the speech-therapy regime in the long-term rehabilitation pathway. Few apps for speech therapy have been subject to clinical trials, especially on a self-delivered platform. In a crossover design study, the Comprehensive Aphasia Test (CAT) and Cookie Theft Picture Description (CTPD) were used to measure untrained improvement in a group of chronic expressive aphasic patients after using a speech therapy app. A pilot study (n = 3) and crossover design (n = 7) comparing the therapy app with a non-language mind-game were conducted. Patients self-selected their training on the app, with a recommended use of 20 minutes per day. There was significant post-therapy improvement on the CAT and CTPD but no significant improvement after the mind-game intervention, suggesting there were language-specific effects following use of the therapy app. Improvements on the CTPD, a functional measurement of speech, suggest that a therapy app can produce practical, important changes in speech. The improvements post-therapy were not due to type of language category trained or amount of training on the app, but an inverse relationship with severity at baseline and post-therapy improvement was shown. This study suggests that self-delivered therapy via an app is beneficial for chronic expressive aphasia.

Ultrasonic vocalization in murine experimental stroke: A mechanistic model of aphasia

PURPOSE

Approximately one-fourth of stroke survivors are aphasic. Speech therapy is the main treatment approach but leaves most patients with chronic disability. Attempts to improve this situation are hampered by a lack of mechanistic understanding of the disability and treatments, reflecting the neglect of this impairment modality in pre-clinical research. Accordingly, we devised a novel murine model of speech-related impairment after stroke to investigate the role of language- and plasticity-associated molecules. Rodents communicate socially with ultrasonic vocalizations (USVs), conveying semantic and semiotic information with complex frequency modulated "songs" and alarm calls.

METHODS

Transient focal cerebral ischemia was induced in male C57BL6 mice via either 30 or 45 minutes of reversible right MCAO using the intraluminal filament technique. Nine days post-operatively brains are stained with TTC and analyzed for infarct volume. For behavioral measures health scores are taken (days 1-4), cylinder tests and USV recordings performed at days 3 and 7 post operatively. Real time PCR was performed at 24 and 48 hour and 7 day time points to quantify mRNA expression of communication-related genes (Foxp2, Foxp1, Srpx2, Cntnap2 and Gapdh). Immunohistochemistry was performed to localize FOXP2 protein.

RESULTS

After middle cerebral artery occlusion of either 30 or 45 minutes duration, mice demonstrate profoundly impaired socially evoked USVs. In addition, there is suppression of the language-associated transcription factor, Forkhead box protein 2 (Foxp2), and its downstream binding partner, contactin-associated protein 2 (Cntnap2).

CONCLUSION

These findings set a foundation for further studies of mechanisms and novel treatment strategies for post-stroke vocalization impairments.

Raising public awareness of aphasia in southern Ontario, Canada: A survey

PURPOSE

Despite the relatively high prevalence of aphasia, research indicates that, world-wide, public awareness of aphasia is lacking. Of the surveys that have been conducted internationally, none has studied the Canadian public's awareness of aphasia. The purpose of the present survey was to assess public awareness and basic knowledge of aphasia of individuals in southern Ontario, Canada.

METHOD

Using the same questionnaire that has been used in other countries, face-to-face surveys were conducted in public places (e.g. parks) at various locations in southern Ontario. Respondents were asked questions pertaining to their awareness and knowledge of aphasia. The number of surveys retained for analysis was 831. In addition to an evaluation of public awareness and knowledge of aphasia, the potential influences of age, gender, and occupation were analysed. For those who had heard of aphasia, questions were asked to determine how or where they had heard of aphasia.

RESULT

Consistent with the literature, overall public awareness and basic knowledge of aphasia in southern Ontario was found to be limited. The factors of age, gender and occupation were found to influence the results.

CONCLUSION

This investigation supports the need for better promotion of aphasia awareness to the public in southern Ontario and, by extension, in Canada.

A qualitative study of legal and social justice needs for people with aphasia

This paper presents an exploratory investigation of situations in which people with aphasia may be vulnerable to legal and access to justice issues. The study used a qualitative descriptive approach to analyse 167 de-identified transcriptions of previously collected interviews, with 50 participants with mild-to-severe aphasia following stroke, 48 family members, and their treating speech-language pathologists. Situations experienced by people with aphasia and their family members were coded using key-word searches based on the previously published framework developed by Ellison and colleagues to describe situations of vulnerability to legal and access to justice needs for older people. Health and financial and consumer situations were most frequently identified in the data. Additionally, there were a number of situations found specifically relating to people with aphasia involving their signatures and credit card use. Instances of discrimination and abuse were also identified, and, although infrequent, these issues point to the profound impact of aphasia on the ability to complain and, hence, to ensure rights to care are upheld. The findings of this study are consistent with previous research in suggesting that legal and access to justice needs are an important issue for people with aphasia and their families.

Aphasia rehabilitation in Australia: Current practices, challenges and future directions

This study reports on current aphasia rehabilitation practices of speech-language pathologists in Australia. A 30-item web-based survey targeted approaches to aphasia rehabilitation, education, discharge, follow-up practices, counselling, interventions to improve communication access, community aphasia support services, and challenges to practice. One hundred and eighty-eight surveys were completed representing ~33% of the potential target population, with 58.5% urban and 41.5% rural participants across all states and territories. Respondents reported embracing a wide variety of approaches to aphasia rehabilitation; however, significant challenges in providing aphasia management in acute and residential care were identified. Low levels of knowledge and confidence were reported for both culturally and linguistically diverse clients and discourse approaches. Group and intensive services were under-utilized and clinicians reported inflexible funding models as major barriers to implementation. Few clinicians work directly in the community to improve communicative access for people with aphasia. Despite the chronic nature of aphasia, follow-up practices are limited and client re-entry to services is restricted. Counselling is a high frequency practice in aphasia rehabilitation, but clinicians report being under-prepared for the role. Respondents repeatedly cited lack of resources (time, space, materials) as a major challenge to effective service provision. Collective advocacy is required to achieve system level changes.
