Efficacy of a self-administered treatment using a smart tablet to improve functional vocabulary in post-stroke aphasia: a case-series study

A mixed-studies systematic review of self-administered music interventions (SAMIs) for psychological wellbeing in people with chronic health conditions: Meta-analysis and narrative summary

OBJECTIVE

This mixed-studies systematic review examined how self-administered music interventions (SAMIs) influenced psychological wellbeing for people with chronic health conditions.

METHODS

We searched 7 databases and performed citation and reference checks to find studies that implemented SAMIs for psychological outcomes in adults with chronic health conditions published between January 1990 and March 2023. Risk of bias was assessed using Downs and Black's quality assessment checklist criteria. Data were synthesised using meta-analysis and narrative summary.

RESULTS

We included 21 articles (934 participants). Meta-analyses demonstrated significant effects of SAMIs on outcomes measuring post-test (SMD = 0.72) and long-term depression (SMD = 0.51), post-test generic (SMD = 0.55) and disease-specific (SMD = 0.56) psychological quality of life, and post-test mood disturbance (SMD = 0.64). A small effect suggested that SAMIs with multiple in-person sessions guided by a music therapist may reduce anxiety (SMD = 0.37) CONCLUSION: SAMIs may improve psychological wellbeing in people with chronic health conditions. Long-term benefits of SAMIs have been recognised for the depression outcome.

PRACTICE IMPLICATIONS

Encouraging people with chronic health conditions to self-administer music interventions may provide benefits to their psychological wellbeing.

Experiences of participating in group-based rehabilitation programmes: A qualitative study of community-dwelling adults with post-stroke aphasia

BACKGROUND

People with post-stroke aphasia tend to have smaller social networks, a higher risk of depression and poorer health-related quality of life than those who do not have aphasia after stroke. Stroke-specific or general rehabilitation programmes offered by community-based organizations are commonly group-based and involve discussions among group members with or without stroke. Research has shown that people with post-stroke aphasia may be unable to participate fully in verbal sharing of experiences and exchange of thoughts.

AIMS

To explore the experiences of people with post-stroke aphasia in relation to participating in group-based rehabilitation programmes organized by community-based organizations.

METHODS & PROCEDURES

A qualitative design was adopted, including individual, semi-structured interviews with 20 adults with post-stroke aphasia recruited from community-based rehabilitation centres and support groups. The participants had a mean age of 68.86 ± 13.54 years and a mean post-stroke duration of 9.24 ± 7.72 years. They had participated in at least one group-based rehabilitation programme organized by community-based organizations in the past year. The participants were asked about their experiences of attending group-based programme(s), thoughts and feelings while interacting with the facilitators and group members, and satisfaction with their participation. The interview data were thematically analysed.

OUTCOMES & RESULTS

Three themes were identified: (1) hurdles to active and fulfilling participation including the dominance of verbal sharing, short duration of the programme, being a minority in the group and accumulated negative experiences; (2) strategies adopted to improve participation including accepting a reduced speaking ability, having support from caregivers, and trying mobile apps to vocalize and supplement meanings; and (3) a preference for certain group conditions including receiving invitations by staff with whom they were familiar, groups that are led by experienced facilitators, a large or small group, the dominance of non-verbal activities, and inclusion of only people with post-stroke aphasia.

CONCLUSIONS & IMPLICATIONS

The findings showed that people with post-stroke aphasia experience difficulties participating more actively in group-based rehabilitation programmes due to hurdles in terms of the structure and format of the programmes and accumulation of negative experiences. Facilitating positive group experiences for these people with innovative methods, such as using technology and providing professional and standby support, would be helpful. Longer sessions with smaller groups, exclusively including people with post-stroke aphasia and involving more non-verbal activities to help them express feelings, are suggested to optimize the benefits they derive from these group-based programmes.

WHAT THIS PAPER ADDS

What is already known on the subject Stroke-specific or general group-based rehabilitation programmes are commonly offered by community-based organizations to support the recovery of people with or without stroke. However, some people with post-stroke aphasia may be unable to participate fully in verbal sharing of experiences and exchange of thoughts during these group-based programmes, which can limit the benefits they derive from these programmes. What this paper adds to existing knowledge This study explored the experiences of people with post-stroke aphasia in relation to participating in group-based rehabilitation programmes not specifically designed for people with stroke-induced aphasia organized by community-based organizations. The findings provide an insight into how these people participate in groups, their thoughts and feelings during interactions with the facilitators and group members, their satisfaction with their level of participation, and the characteristics of the groups they prefer to join. What are the potential or actual clinical implications of this work? People with post-stroke aphasia experience difficulties participating more actively in group-based programmes due to hurdles in terms of the structure and format of the group-based programmes and accumulation of negative experiences contributing to decreased motivation to participating in groups. More positive group experiences can be fostered by adopting longer sessions with smaller groups that exclusively include people with post-stroke aphasia and involve more non-verbal activities to help them express their feelings. Communication partner training for facilitators and the use of technology to support communication are suggested to promote active and fulfilling participation of the people with aphasia in group-based programmes.

Conversation as an Outcome of Aphasia Treatment: A Systematic Scoping Review

PURPOSE

Conversation-focused speech-language pathology services are a top priority for people living with aphasia, but little is known about how researchers measure conversation as an outcome of treatment. This scoping review was undertaken to systematically review the evidence regarding the measurement of conversation in aphasia studies and to identify current practices and existing gaps.

METHOD

A systematic literature search was conducted for studies published between January 1995 and September 2019 in multiple electronic databases. Covidence software was used to manage search results, study selection, and data charting processes. Data were extracted from each study and then collated and organized to elucidate the breadth of approaches, tools, or procedures oriented to measuring conversation as an outcome and identify gaps in the existing literature.

RESULTS

The systematic search of the literature resulted in 1,244 studies. A total of 64 studies met inclusion criteria and were included in the review. The review summarizes the various tools and procedures used to measure conversation as an outcome of aphasia intervention, including variations in data collection and analysis procedures. The review also evaluates the quality of conversation measures in terms of psychometric properties and informal measures of validity. There was a total of 211 measures used across the 64 studies.

CONCLUSIONS

While there was no clear measure that was objectively superior, several measures show promise and warrant future exploration. Some of the orientations, conceptualizations, and procedures we have presented can be seen as options that might be included in a future conversation-focused core outcome set.

Technology-Dependent Rehabilitation Involving Action Observation and Movement Imagery for Adults with Stroke: Can It Work? Feasibility of Self-Led Therapy for Upper Limb Rehabilitation after Stroke

BACKGROUND

Motor (re)learning via technology-dependent therapy has the potential to complement traditional therapies available to older adults living with stroke after hospital discharge and increase therapy dose. To date, little is known about the feasibility of technology-dependent therapy in a home setting for this population.

OBJECTIVE

To develop a technology-dependent therapy that provides mental and physical training for older adults with stroke and assess feasibility. Specifically we ask, "Can it work"?

DESIGN

Single group repeated measures.

METHODS

13 participants, aged 18 years and over, were recruited over a six-month period. All participants had mild upper limb impairment following a stoke and were no longer receiving intensive rehabilitation. All participants received 18 days of technology-dependent therapy in their own home. Information was gathered on recruitment and retention, usability, and suitability of outcome measures.

RESULTS

11 participants completed the study. The recruitment rate (number recruited/number canvassed; 10.7%) suggests 1907 participants would need to be canvassed to recruit the necessary sample size (n = 204) for a definitive trial designed to provide 90% power at 5% level of significance to detect a clinically meaningful difference of 5.7 points on the Action Research Arm Test. The usability of the application was rated as exceptional on the System Usability Scale. Effectiveness cannot be determined from this study; however, there was a trend for improvement in measures of upper limb function and emotional well-being. Limitations. The study was limited by a relatively small sample size and lack of control group.

CONCLUSIONS

This study demonstrated proof of concept of a technology-dependent therapy for upper limb rehabilitation following stroke. The data suggest a definitive trial is feasible, additional strategies to improve recruitment should be considered. Outcome measures aligned with the residual motor function of participants are required.

Behavioral interventions for poststroke aphasia

There is a long history of behavioral interventions for poststroke aphasia with hundreds of studies supporting the benefits of aphasia treatment. However, interventions for aphasia are complex with many interacting components, and no one treatment is appropriate for all persons with aphasia. We present a novel, simple framework for classifying aphasia interventions. The framework is incorporated within the overarching International Classification of Functioning, Disability, and Health (ICF) model and is consistent with the commonly-held definition that aphasia is a multimodality disorder that impairs, in varying degrees, the understanding and expression of both oral and written language modalities. Furthermore, within the language impairment level, it distinguishes between the linguistic areas of phonology, semantics, and syntax that may be impaired individually or in combination. We define the terminology of the proposed framework and then categorize some common examples of behavioral interventions for post-stroke aphasia. We describe some of these interventions in greater detail to illustrate the extensive toolbox of evidence-based treatments for aphasia. We address some key issues that clinicians, usually speech-language pathologists, consider when selecting interventions for their specific patients with aphasia, including dose. Finally, we address various models of service delivery for persons with aphasia such as Intensive Comprehensive Aphasia Programs (ICAPs) and Aphasia Centers.

TDQ-30-A New Color Picture-Naming Test for the Diagnostic of Mild Anomia: Validation and Normative Data in Quebec French Adults and Elderly

OBJECTIVE

A reduction in lexical access is observed in normal aging and a few studies also showed that this ability is affected in individuals with subjective cognitive decline. Lexical access is also affected very early in mild cognitive impairment as well as in major neurocognitive disorders. The detection of word-finding difficulties in the earliest stages of pathological aging is particularly difficult because symptoms are often subtle or mild. Therefore, mild anomia is underdiagnosed, mainly due to the lack of sensitivity of naming tests. In this article, we present the TDQ-30, a new picture-naming test designed to detect mild word-finding deficits in adults and elderly people.

METHOD

The article comprises three studies aiming at the development of the test (Study 1), the establishment of its validity and reliability (Study 2), and finally, the production of normative data for French-speaking adults and elderly people from Quebec (Study 3).

RESULTS

The results showed that the TDQ-30 has good convergent validity. Also, the TDQ-30 distinguished the performance of healthy controls from those of participants with mild cognitive impairment, Alzheimer's disease, and post-stroke aphasia. This suggests good discriminant validity. Finally, this study provides normative data computed from a study sample composed of 227 participants aged 50 years and over.

CONCLUSIONS

The TDQ-30 has the potential to become a valuable picture-naming test for the diagnosis of mild anomia associated with pathological aging.

An overview of the digital solutions for helping people with aphasia through bibliometric analysis

This paper gives insights into recent research developments in the field of digital solutions for people with aphasia and tries to analyse its impact on their rehabilitation. A bibliometric research approach is used for data collection. Relevant studies were extracted from seven major academic databases from years 2000 to 2019 inclusive. The systematic process resulted in 986 studies. The average growth in this field is 4%, which is less compared to other research areas. However, the average citations per paper is 7.27, which represents a medium level of publication quality. Scopus and Web of Science are leading databases for the number of studies (379 and 264) and quality of publications (P-Index: 49.26 and 32.85), respectively. The USA, with 42% of publications, leads this research field, followed by the UK with 15%. Both countries have national aphasia strategies in place through charities (not government level strategies), which potentially contributed to their research leadership. The results show that recent advances in digital solutions have the potential to support people with aphasia. However, further work is needed at both academic and government levels to deliver more research contributions and funding for the rehabilitation of people with aphasia.

•

The countries with clear national aphasia strategies in place lead this research field.

•

Western countries carry most of the research for aphasia; the global view of this research area is still messing.

•

Personal care, in combination with digital solutions, can yield better results.

•

The fully immersive virtual reality solutions offer close to real-life interaction experience for the people with aphasia and their surroundings inside the virtual space.

Adjunctive Approaches to Aphasia Rehabilitation: A Review on Efficacy and Safety

Aphasia is one of the most socially disabling post-stroke deficits. Although traditional therapies have been shown to induce adequate clinical improvement, aphasic symptoms often persist. Therefore, unconventional rehabilitation techniques which act as a substitute or as an adjunct to traditional approaches are urgently needed. The present review provides an overview of the efficacy and safety of the principal approaches which have been proposed over the last twenty years. First, we examined the effectiveness of the pharmacological approach, principally used as an adjunct to language therapy, reporting the mechanism of action of each single drug for the recovery of aphasia. Results are conflicting but promising. Secondly, we discussed the application of Virtual Reality (VR) which has been proven to be useful since it potentiates the ecological validity of the language therapy by using virtual contexts which simulate real-life everyday contexts. Finally, we focused on the use of Transcranial Direct Current Stimulation (tDCS), both discussing its applications at the cortical level and highlighting a new perspective, which considers the possibility to extend the use of tDCS over the motor regions. Although the review reveals an extraordinary variability among the different studies, substantial agreement has been reached on some general principles, such as the necessity to consider tDCS only as an adjunct to traditional language therapy.

The feasibility, usability and acceptability of a tablet-based aphasia therapy in the acute phase following stroke

QUESTION

Independent practice via an application with a language exercise program for aphasia, as an add-on to conventional care can be a good solution to intensify aphasia therapy. The aim of this prospective trial was to investigate the feasibility, usability and acceptability of the newly-developed aphasia exercise program in the 'Speech Therapy App (STAPP)' in the acute phase post-stroke.

METHODS

All eligible people with aphasia following stroke (<2 weeks post-stroke) admitted to the Stroke Unit of Ghent University Hospital were recruited in this prospective clinical trial between September 2018 and December 2019. After linguistic assessments and two short training sessions, participants were asked to practice independently with 'STAPP' for at least 30 min/day during hospitalization. Exercises were individually tailored and adjusted if necessary. Outcome was measured by recruitment, adherence and retention rates, usability questionnaires and a visual analogue scale for satisfaction.

RESULTS

Twenty-five (mean age 65 years (SD = 17), 14 females) of 31 eligible people with aphasia were enrolled in this trial (recruitment rate = 81 %). All participants but one (23/24) practiced with the language app until the end of hospitalization (retention rate = 96 %). Ten participants practiced at least 30 min/day (adherence rate = 42 %). Participants reported they learned to work quickly with the app (92 %; agreed/totally agreed), the app was easy to use (88 %), they could work independently (79 %), practiced their language (67 %) and wanted to continue working with the app at home (79 %). Acceptability was high (median satisfaction rate 91 %; IQR = 75-100).

CONCLUSION

The aphasia exercise program in 'STAPP' is feasible to use as an additional rehabilitation tool along with standard of care in the acute phase post-stroke. Further research is needed to assess the efficacy. CLINICAL TRIAL REGISTRATION-URL: https://clinicaltrials.gov/ct2/show/NCT03679637.

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

Background

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

Main text

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

Conclusion

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