Experiences of People with Aphasia Receiving Enhanced Community-Based Speech-Language Pathology Provided by Speech-Language Pathology Students

INTRODUCTION

Treatment intensity for people with aphasia (PWA) is a significant factor in enhancing recovery. Personal factors such as fatigue, physical endurance, and motivation as well as clinician availability have been described as barriers to increased intensity. The use of student therapists has been shown to assist with addressing service gaps.

METHODS

The aim of the study was to explore the experiences of PWA who received enhanced community-based treatment delivered by speech-language pathology (SLP) students. Enhanced community-based treatment was defined as three or more treatment sessions per week targeting communication. Semi-structured interviews were conducted with 10 PWA living in New Zealand. Interview data were analysed with reflexive thematic analysis.

RESULTS

Two themes and six sub-themes were developed. Theme 1 related to intensity and included more treatment is better than less (sub-theme 1), there's a "right time" for more intensive treatment (sub-theme 2), the hard work is worth the effort (sub-theme 3). Theme 2 related to working with SLP students; it didn't feel like they were students (sub-theme 4), we just got on so well (sub-theme 5), and they listened to what I wanted (sub-theme 6).

CONCLUSIONS

The findings confirm that PWA value access to more intensive treatment and desire involvement in decisions about flexible treatment schedules. PWA have positive experiences when treatment is provided by SLP students. Implications for clinical practice and future research directions are discussed.

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.

More than one way to improve a CAT: Outcomes and reflections on two iterations of the Queen Square Intensive Comprehensive Aphasia Programme

Background

The field of human expert performance teaches us that high quality, high-dose guided practice is required to make large gains in cognitively driven acts. The same also seems to be true for people with acquired brain injury, yet therapy services for people with aphasia (PWA) have traditionally not been designed with this in mind. Intensive Comprehensive Aphasia Programmes (ICAPs) are one way to address the chronic under-dosing of therapy that most PWA experience.

Aims

There are several ways to deliver an ICAP; here we describe two iterations of our Queen Square ICAP. There was a 20-month COVID-induced pause between the Year 1 (Y1) and Year 2 (Y2) ICAP groups. We analyse ICAP-induced changes in both groups of PWA on a series of key outcome measures that span the International Classification of Functioning, Disability and Health, covering language impairment and function as well as mood and social participation.

Methods & Procedures

Forty-six PWA took part in Y1 and 44 in Y2. The PWA were all in the chronic stage post stroke and varied in aphasia severity from mild to severe, with the Y2 group being more impaired than Y1. Quantitative data was collected before and after the ICAP. The Y2 therapy team provided independent reflections on their experiences of delivering an ICAP.

Outcomes & Results

ICAP-related changes in outcome measures (impairment, function and goal attainment) were generally comparable for the Y1 and Y2 groups, with both groups' speech production abilities improving the most. Both groups made clinically and statistically significant gains on the main quality of life measure. Participation in the ICAP made a big difference to PWAs' self-confidence ratings. Their mood ratings also improved significantly, although they were not, on average, in the depressed range at baseline (directly pre-ICAP). All improvements achieved in both groups were maintained at the 3-month follow-up, highlighting the lasting effects that ICAPs can provide.

Conclusions

Evidence continues to accrue that ICAPs are an efficient way of increasing the dose of expert coaching required for people with chronic aphasia to make clinically meaningful improvements in their communicative abilities and quality of life. The main challenge remaining is convincing health-care providers to invest in them.

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

INTRODUCTION

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

PURPOSE

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSION

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

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.

NUVA: A Naming Utterance Verifier for Aphasia Treatment

•

NUVA automatically assesses online word naming attempts in aphasia therapy.

•

Significantly more accurate and faster than leading commercial speech recognition.

•

Accuracies between 83.6% and 93.6% validate use in clinical research.

Anomia (word-finding difficulties) is the hallmark of aphasia, an acquired language disorder most commonly caused by stroke. Assessment of speech performance using picture naming tasks is a key method for both diagnosis and monitoring of responses to treatment interventions by people with aphasia (PWA). Currently, this assessment is conducted manually by speech and language therapists (SLT). Surprisingly, despite advancements in automatic speech recognition (ASR) and artificial intelligence with technologies like deep learning, research on developing automated systems for this task has been scarce. Here we present NUVA, an utterance verification system incorporating a deep learning element that classifies 'correct' versus' incorrect' naming attempts from aphasic stroke patients. When tested on eight native British-English speaking PWA the system's performance accuracy ranged between 83.6% to 93.6%, with a 10-fold cross-validation mean of 89.5%. This performance was not only significantly better than a baseline created for this study using one of the leading commercially available ASRs (Google speech-to-text service) but also comparable in some instances with two independent SLT ratings for the same dataset.

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

Background

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

Design and participants

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

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

Results

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

Conclusions

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

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.

Dysphagia screening using an allied health assistant delegation model: service considerations for implementation

PURPOSE

Three facilities, involved in introducing a model of Allied Health Assistant (AHA) delegated dysphagia screening, examined barriers and facilitators to service implementation.

MATERIALS AND METHODS

The 3 facilities varied in size, services and location. AHAs (n = 4) and speech-language therapists (SLTs; n = 4) directly involved in implementation at each site completed semi-structured interviews exploring the implementation experience. Analysis was guided by the Consolidated Framework for Implementation Research (CFIR).

RESULTS

There was differential implementation across the sites. Facilitators to implementation fell within the CFIR Innovation Characteristic domain, with the "relative advantage" of the model and "design, quality and packaging" of the training and implementation resources being key facilitators. Barriers related to the Innovation Characteristic domain, regarding the tool's "adaptability" in terms of screening tools selected and the implementation environment. Issues with the Inner Setting domain, specifically the "structural characteristics," the "compatibility" of the model and the "relative priority" of the model's implementation within other organizational priorities were also barriers.

CONCLUSIONS

Although the service model was perceived to have relative advantage, compatibility with local work-flow priorities and service needs must be thoroughly considered if AHA delegated dysphagia screening is to be beneficial as a service model to address increasing dysphagia referral demands.IMPLICATIONS FOR REHABILITATIONDysphagia is a disabling condition which may result in medical, social and operational complications.The demands of screening, assessing, managing and providing rehabilitation for dysphagia are increasing, therefore alternative models of service delivery including delegation are increasingly being considered and implemented.This study provides evidence regarding the context and facilitators of successful AHA dysphagia screening model implementation.This evidence contributes to a growing knowledge base of delegation practices for the management of staffing resources and building of capacity for rehabilitation service delivery.

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.

Delegation models in dysphagia management: Current policy, clinical perceptions and practice patterns

Purpose: Delegation to Allied Health Assistants (AHAs) is an effective workforce solution in a number of areas of adult speech-language pathology (SLP) practice. However, reports of AHA delegation in the area of dysphagia management are limited. The aim of this study was to synthesise information from policy documents and current clinical practice to examine the nature of AHA delegation in dysphagia management.Method: A mixed method design involving a document review of 13 policy documents on AHA delegation, and a survey of 44 SLP managers regarding current delegation models.Result: Policy and current practice were largely congruent. Despite policy support for AHA delegation, 77% reported using delegation models but only 26% used them fairly often/very often in dysphagia management. Both policy and survey findings support AHA training prior to task delegation, however, the nature of training was unspecified. Good governance is integral to successful delegation and managers recognised the need to increase standardisation of AHA capability assessment.Conclusion: AHA delegation in dysphagia management is supported by policy and is being implemented in clinical services. However further work detailing governance and training requirements is needed, as well as systematic evaluation of the safety and benefits of these models.

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

Background

Speech and language therapy provision for aphasia (a language disorder) post stroke has been studied over time through surveys completed by speech and language therapists. This paper revisits provision based on what was received by 278 patients in 21 UK speech and language therapy departments in 2014–2016.

Aims

To explore the speech and language therapy received by community dwelling people with post stroke aphasia in the UK.

Methods and procedures

A quantitative content analysis was conducted by two speech and language therapist researchers. Therapy goals recorded were coded into categories and subcategories. Descriptive statistics were used to identify the frequency with which goal categories were targeted, average therapy time received, length and frequency of therapy sessions, personnel involved and mode of delivery.

Outcomes and results

Forty-five percent of participants were in receipt of therapy in the three month window observed. Six goal categories were identified. Rehabilitation was the most frequent (60%) followed by enabling (17.2%), review (4.3%), assessment (3.6%), supportive (3.5%) and activity to support therapy (2.8%). The median amount of therapy received in three months was 6.3 hours at an average of one 60-minute session every two weeks. Seventy-seven percent of therapy sessions were delivered by qualified speech and language therapists and 23% by assistants. Ninety percent of sessions were one to one, face to face sessions whilst 9.5% were group sessions.

Discussion

In line with previous reports, speech and language therapy for community dwelling stroke survivors with aphasia is restricted. Rehabilitation is a large focus of therapy but the intensity and dose with which it is provided is substantially lower than that required for an effective outcome. Despite this, one to one face to face therapy is favoured. More efficient methods to support more therapeutic doses of therapy are not commonly used in routine clinical services.

Priorities for Closing the Evidence-Practice Gaps in Poststroke Aphasia Rehabilitation: A Scoping Review

OBJECTIVE

To identify implementation priorities for poststroke aphasia management relevant to the Australian health care context.

DATA SOURCES

Using systematized searches of databases (CINAHL and MEDLINE), guideline and stroke websites, and other sources, evidence was identified and extracted for 7 implementation criteria for 13 topic areas relevant to aphasia management. These 7 priority-setting criteria were identified in the implementation literature: strength of the evidence, current evidence-practice gap, clinician preference, patient preference, modifiability, measurability, and health effect.

STUDY SELECTION

Articles were included if they were in English, related to a specific recommendation requiring implementation, and contained information pertaining to any of the 7 prioritization criteria.

DATA EXTRACTION

The scoping review methodology was chosen to address the broad nature of the topic. Evidence was extracted and placed in an evidence matrix. After this, evidence was summarized and then aphasia rehabilitation topics were prioritized using an approach developed by the research team.

DATA SYNTHESIS

Evidence from 100 documents was extracted and summarized. Four topic areas were identified as implementation priorities for aphasia: timing, amount, and intensity of therapy; goal setting; information, education, and aphasia-friendly information; and constraint-induced language therapy.

CONCLUSIONS

Closing the evidence-practice gaps in the 4 priority areas identified may deliver the greatest gains in outcomes for Australian stroke survivors with aphasia. Our approach to developing implementation priorities may be useful for identifying priorities for implementation in other health care areas.

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.

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.

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.

Transcranial Direct Current Stimulation as a Novel Method for Enhancing Aphasia Treatment Effects

Abstract. Neuromodulation is an exciting area of development. Currently, there is significant interest in academia, industry, and clinical practice where an effective and acceptable transcranial direct current stimulation (tDCS) kit for use in clinical rehabilitation would offer much benefit to patients’ treatment. In this review, I discuss the latest group studies investigating current tDCS methods for enhancing aphasia treatment effects in post-stroke (sub-acute and chronic) and primary progressive aphasia (PPA) patient populations. This field is still new, and many more investigations with larger samples of patients are needed. Nevertheless, in the studies completed to date, on-line tDCS paired with language rehabilitation was feasible, safe, well tolerated, and sham controlled. Results on the effectiveness of tDCS at boosting recovery outcomes are preliminary but promising with a number of themes emerging. I highlight some of these themes and future directions toward identifying those patients who are likely to respond to specific tDCS and behavioral therapies. This would provide an empirical basis from which to investigate specific aphasia interventions in future multicenter clinical trials and could greatly improve the quality of aphasia treatment for stroke and PPA patients.

'I do the best I can': an in-depth exploration of the aphasia management pathway in the acute hospital setting

PURPOSE

While research has begun to explore the management of aphasia across the continuum of care, to date there is little in-depth, context specific knowledge relating to the speech pathology aphasia management pathway. This research aimed to provide an in-depth understanding of the current aphasia management pathway in the acute hospital setting, from the perspective of speech pathologists.

METHOD

Underpinned by a social constructivist paradigm, the researchers implemented an interpretive phenomenological method when conducting in-depth interviews with 14 Australian speech pathologists working in the acute hospital setting. Interview transcripts and interviewer field notes were subjected to a qualitative content analysis.

RESULTS

Analysis identified a single guiding construct and five main categories to describe the management of aphasia in the acute hospital setting. The guiding construct, First contact with the profession, informed the entire management pathway. Five additional main categories were identified: Referral processes; Screening and assessment; Therapeutic intervention; Educational and affective counselling; and Advocacy.

CONCLUSIONS

Findings suggest significant diversity in the pathways of care for people with aphasia and their families in the acute hospital setting. Additional support mechanisms are required in order to support speech pathologists to minimise the evidence-practice gap. Implications for Rehabilitation Significant diversity exists in the current aphasia management pathway for people with acute post-stroke aphasia and their families in the acute hospital setting. Mechanisms that support speech pathologists to minimise the evidence-practice gap, and consequently reduce their sense of professional dissonance, are required.

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.

Speech pathology services for people with aphasia: what is the current practice in Singapore?

PURPOSE

This study reports on current provision of aphasia services by speech pathologists in Singapore.

METHOD

A 44-item web-based survey was conducted looking into areas of service delivery, assessment, cultural and linguistic adaptations, clinical approaches, education of clients, recovery, goal setting and discharge as well as scope and challenges to practice.

RESULTS

A total of 36 surveys were completed representing approximately 86% of the potential target population. The intensity of aphasia services provided was well below that recommended by the literature. Participants reported embracing approaches to aphasia rehabilitation that spanned across the ICF domains. Numerous challenges were reported in providing aphasia services. These included the lack of locally relevant resources for aphasia, lack of family support and patient motivation, manpower shortages as well as barriers such as transport and cost restricting access to services.

CONCLUSIONS

This research reveals several findings with considerable implications for practice planning and future direction in aphasia rehabilitation. There is a need for the development of locally relevant aphasia resources to enable comprehensive provision of aphasia services. In addition, further investigation is required to tackle the resource challenges faced by the profession and improve community support for people with aphasia. Implications for Rehabilitation Speech pathology services for aphasia in Singapore This article has identified the challenges of providing aphasia services in the Singapore context. Further investigation is required to address the key issues to improve aphasia services in Singapore. This includes developing locally relevant resources, looking at means like telerehabilition to tackle resource challenges, and improving community support for people with aphasia.

Stroke: has speech and language therapy been shown not to work?

In a recent trial investigating the effectiveness of speech and language therapy versus a control intervention in poststroke aphasia, patient outcome improved equally in both groups. However, flaws in the study relating to design of the control intervention, inadequate therapy 'dose', and the interpretation of null results should be highlighted.

Delivering for aphasia

Providing a quality service for people with aphasia is a primary goal of speech-language pathologists working with neurogenic communication disorders. This paper reviews what is known about the incidence and prevalence of aphasia and what services are provided for people with aphasia. On the basis of the stroke data, the incidence of aphasia in the developed world ranges between 0.02-0.06% with prevalence ranging between 0.1-0.4%. Average hours of treatment for aphasic people in the developed world ranges between 1-5 hours per week, with a great deal of variability, although recent research suggests that intense treatment of ∼9 hours per week over a relatively short period is needed in order to be effective. It is concluded that there is a significant gap between what the research suggests is the appropriate amount of treatment and actual provision throughout the English-speaking world.

Aphasia rehabilitation and the role of computer technology: can we keep up with modern times?

Numerous computer applications have been developed specifically for aphasia rehabilitation. In this paper, the role of these computer programs is discussed in relation to three complementary treatment approaches in aphasia rehabilitation: disorder-oriented treatment, functional treatment, and participation-oriented treatment. Most of the programs available focus on disorder-oriented treatment and several studies have reported a beneficial effect on language skills. Nowadays, in the context of disorder-oriented treatment, these applications are indispensible to achieve an adequate treatment frequency of at least 2 hours per week. Computer applications aiming at functional and social participation goals are less well-developed. Several studies show that high-technology AAC can be used to support off-line communication. Moreover, it is reported that the AAC training has a positive effect on overall communicative functioning. In the near future, computer applications for interactive communicative training may become an important tool in aphasia rehabilitation. Theoretically, the internet offers excellent opportunities to improve social participation for people with aphasia, but reading and writing problems limit their access to the internet. So far, only a few initiatives have been reported to support and increase their access.

Dysphagia Evaluation Practices of Speech and Language Therapists in Ireland: Clinical Assessment and Instrumental Examination Decision-Making

The purpose of this study was to investigate clinical assessment practices and instrumental examination decision-making by speech and language therapists (SLTs) in Ireland. A 21-question survey (including patient scenarios) was sent to 480 SLTs in Ireland. A total of 261 completed surveys were returned (54%), providing demographic information on SLTs currently working in Ireland and their services. Of these 261 surveys, 70 provided the data for the study, focusing on SLTs currently working in dysphagia, with adults/seniors at least some of the time. The results also showed clinician variability regarding which components are included in a bedside clinical examination of swallowing, with a high degree of consistency for only 11 of the 20 components. Clinicians agreed in their instrumental vs. noninstrumental evaluation recommendations for two of the six patient scenarios, with wide variability in clinical decision-making. Possible influences on clinical decision-making are discussed in relation to the findings of similar previous studies, as well as the current status and future needs of dysphagia training and services in Ireland.
