The efficacy of group communication treatment in adults with chronic aphasia

An Interprofessional Approach to Aural Rehabilitation for Adults with Hearing Loss and Cognitive Concerns

Individuals with hearing loss are at risk for cognitive decline. The traditional approach to audiological care does not typically involve a team approach that addresses cognitive concerns. While cognitive screening is within the scope of practice in audiology, audiologists are not typically trained in interpreting screening results or providing rehabilitation that supports cognitive health. However, as growing evidence shows that hearing loss is tied to cognitive decline, a team approach is required to support whole-person care. Speech-language pathologists, who specialize in optimizing communication, are best situated to collaborate with audiologists to provide holistic aural rehabilitation. Audiologists and speech-language pathologists who partner to support a client's communication skills and social relationships play an important role in the life of an individual with hearing loss. In this perspective, we describe relevant background information about hearing loss and cognition and present an interprofessional approach to aural rehabilitation for adults with hearing loss who have cognitive concerns. We also discuss implications for future research.

Pilot Results for ECoLoGiC-Tx: A New Conversation-Level Intervention Improving Language in People With Moderate to Severe Aphasia

PURPOSE

This study reports pilot data for a novel intervention, ECoLoGiC-Tx, delivered to four people with moderate to severe aphasia. ECoLoGiC-Tx addresses language and communication in unstructured, participant-led conversation. The speech-language pathologist (SLP) uses a framework to choose turns that facilitate a social interaction. When communication breakdown occurs, the SLP implements a least-to-most hierarchy to maximize the people with aphasia's (PWA's) independence in self-repair. ECoLoGiC-Tx draws its theoretical underpinnings from conversation analysis and theories of rehabilitation, including principles of complexity, neuroplasticity, and learning.

METHOD

Four PWA attended 60-min sessions twice weekly for 10 weeks. Assessment occurred at pretreatment, posttreatment, and 6-week maintenance. Outcomes included established discourse measures for conversation and monologue, tests of language and functional communication, and patient-/family-reported outcome measures (P/FROMs). Discourse samples were collected three times per assessment. Interrater reliability and fidelity for assessment and treatment procedures are reported.

RESULTS

Participants presented with Broca's aphasia (one moderate, one severe) or conduction aphasia (one moderate, one severe). Each demonstrated improvements in discourse, test batteries, and P/FROMs. They all demonstrated reduced aphasia severity measured by the Western Aphasia Battery-Revised at posttreatment or maintenance. Change in conversation and monologue was robust for three participants, but was mixed for one person (P1: moderate Broca's aphasia). P/FROMs indicated improvement at posttreatment and maintenance for all participants. Most treatment gains were maintained at 6-week follow-up.

CONCLUSIONS

This study provides promising results for ECoLoGiC-Tx to improve language function of people with chronic moderate to severe aphasia. Generalization occurred to tests, functional communication, spontaneous conversation, and structured monologue tasks.

Online Aphasia Groups: Navigating Issues of Voice and Identity

PURPOSE

Participation in aphasia groups is associated with increased communication, reduced feelings of social isolation, and increased quality of life. Despite the growing popularity of online aphasia groups, little is known about how to manage conversation in this format. We examined online aphasia book club sessions to examine how the facilitator supported group members' participation in conversation.

METHOD

Interactional sociolinguistic discourse analysis was used to analyze the behaviors and actions of the facilitator and group members. Qualitative data for this study were drawn from four recorded online aphasia book club sessions held through a university's free aphasia clinic on the Zoom web-conferencing platform.

RESULTS

Sociolinguistic discourse analysis revealed strategic facilitator behaviors that served to (a) give members with varying levels of verbal language abilities voice, (b) foreground or background aspects of voice, and (c) minimize her own voice to promote interactional symmetry between herself and group members.

CONCLUSIONS

Identity formed the backdrop for facilitators' actions when leading online groups, guiding decisions about who got to talk, when, for how long, through what modality, and about what topics. A better understanding of the interactions that occur online, such as how to develop and protect the identities of group members, could equip facilitators with the tools necessary for facilitating positive, engaging aphasia therapy groups online.

A Mixed-Methods Exploration of the Experience of People With Aphasia Using Text-to-Speech Technology to Support Virtual Book Club Participation

PURPOSE

This mixed-methods research sought to examine the experience of people with aphasia who used text-to-speech (TTS) support to read a novel for virtual book club participation.

METHOD

Six people with chronic aphasia used a TTS system to review portions of a novel about which they conversed during eight virtual book club meetings occurring over 5 weeks. During one-on-one interactions prior to each meeting, participants answered comprehension questions and provided feedback about reading experiences. Then, during group meetings, they reviewed and discussed relevant book content and predicted upcoming content. During a structured individual interview, participants reflected on their supported reading and book club experience.

RESULTS

Participants reported a range of reading confidence prior to study participation, mostly influenced by decreased comprehension or reading speed. After book club participation, four participants expressed increased confidence. Some reported searching for key words and skipping difficult words as strategies additional to TTS support. All reviewed at least some book sections more than once either with or without TTS support. Highly motivated participants expressed low frustration and high reading ease and enjoyment. Perceived comprehension was roughly consistent with actual comprehension across participants. Most believed TTS support promoted faster reading than otherwise possible. Participants liked adjustable features affecting speech output rate, word or sentence highlighting, and font size. Psychosocial benefits included decreased isolation and increased friendship.

CONCLUSIONS

The findings extend previous evidence about perceived and actual benefits associated with TTS support. People with aphasia express positive experiences when given TTS support during book club participation.

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.

Efficacy of Aphasia Group Conversation Treatment via Telepractice on Language and Patient-Reported Outcome Measures

PURPOSE

Conversation treatment for people with aphasia (PwA) can lead to significant changes in language impairment and quality of life. The COVID-19 pandemic has resulted in the greater use of telepractice treatment delivery. However, there is little evidence regarding the efficacy of telepractice conversation groups. This study investigated the effects of telepractice group conversation treatment on standardized measures of language function and socially oriented/patient-reported outcomes compared to in-person and no-treatment control data.

METHOD

This study used a mixed within- and between-groups design (repeated measure/pre-post treatment), with a single-subject delayed treatment design (Shadish & Rindskopf, 2007) to establish baseline, pretreatment, and posttreatment periods for the telepractice group. Telepractice results pre- and posttreatment were compared with historical in-person and no-treatment control data obtained from a larger randomized control trial (RCT) from DeDe et al. (2019). The historical comparison data were a subset of RCT participants from the same location and included six in-person participants and seven no-treatment control group participants.

RESULTS

Results of standardized testing conducted at baseline, pretreatment, and posttreatment intervals revealed significant improvement from pre- to posttreatment on repetition and picture description tasks for the telepractice group, and significant improvement from pre- to posttreatment on the Aphasia Communication Outcome Measure, total number of relevant utterances, and percentage of complete utterances for the in-person conversation group. No significant differences were observed in the no-treatment groups.

CONCLUSIONS

In contrast to the no-treatment condition, both the in-person and telepractice conditions showed the benefits of conversation group treatment. The in-person treatment condition showed improvements in a wider number of outcome measures than the telepractice condition. Overall, the results prompt further research regarding telepractice group conversation treatment for PwA.

Using bibliotherapy to rebuild identity for people with aphasia: A book club experience

BACKGROUND

Aphasia book clubs were developed to support connecting with literature and reading for pleasure within an aphasia-friendly environment. Bibliotherapy is an evidence-based therapeutic approach, in which a book is selected to address the challenges facing the reader. Its aim is to facilitate a deeper understanding of a lived experience in order to promote healing, strategy development, and adjustment. Aphasia book clubs provide an opportunity to discuss books about the challenges associated with aphasia. A recent book, Identity theft: Rediscovering ourselves after stroke recounts the stroke recovery story of Dr. Debra Meyerson and 22 other stroke survivors. Identity Theft focuses on the need to reconstruct positive identities despite remaining disabilities to facilitate rebuilding rewarding lives. The purpose of this study is to understand the impact of reading Identity Theft in an aphasia book club for people with aphasia (PwA).

METHOD

27 PwA read the book Identity Theft in one of four online aphasia book clubs offered by two universities. Weekly discussions were facilitated by graduate SLP students under the supervision of experienced clinicians. At the end of the 10 week program, semi-structured qualitative interviews were conducted with participants to understand the lived experience. Interviews were analyzed using reflexive thematic analysis.

RESULTS

Analysis of the interview data generated four main themes and 13 subthemes. The main themes included: Mechanism for Reflection, Power of Community, Engaged Learning, and Therapeutic Environment. Interview extracts illustrate the way these themes support increasing self-efficacy and rebuilding a positive identity.

CONCLUSION

The themes align positively with outcomes associated with the bibliotherapy process. Themes also integrate into a self-management model that promotes self-efficacy through education, support, awareness, problem solving and goal setting. Caveats included determining participant readiness to examine recovery issues and facilitator preparation. Aphasia book clubs surrounding psychosocial texts may help PwA reconstruct a positive post-stroke identity.

Delivering group support for people with aphasia in a virtual world: experiences of service providers

PURPOSE

This study explored the acceptability to service providers of delivering a novel group support intervention for people with aphasia (PWA) in a virtual world.

MATERIALS AND METHODS

The service providers were six group coordinators and 10 volunteers. Fourteen of the service providers participated in a semi-structured qualitative interview and 15 took part in a consensus group discussion. Qualitative interviews were analysed using framework analysis. For consensus group discussions, nominal group rankings were analysed and semantically similar responses were identified.

RESULTS

Service providers described the virtual world as a safe space in which to communicate, connect, and experiment. The key barriers were technical, particularly relating to sound and connectivity issues. Service providers suggested a range of improvements to the virtual world and intervention programme. They reported that PWA benefitted from accessing a support group in a virtual world, with opportunities to connect socially and to develop their communication skills.

CONCLUSIONS

Service providers found delivery of group support intervention in a virtual world to be acceptable. The use of a bespoke virtual world to deliver group support intervention may enhance the experience and increase its accessibility, enabling more PWA to benefit from this type of intervention.Implications for rehabilitationPeople with aphasia benefit from group support intervention but may find it difficult to access face-to-face groups.Delivery of group support intervention in a virtual world is acceptable to service providers, can enhance the experience and increase accessibility of groups.Technical challenges present potential barriers when delivering group support in a virtual world, relating particularly to sound and connectivity.Potential benefits of this model of delivery, as perceived by service providers, include opportunities to connect socially and to develop communication skills plus specific and strong levels of enjoyment of the virtual context.

The Severity-Calibrated Aphasia Naming Test

PURPOSE

We present a 20-item naming test, the Severity-Calibrated Aphasia Naming Test (SCANT), that can serve as a proxy measure for an aphasia severity scale that is derived from a thorough test battery of connected speech production, single-word production, speech repetition, and auditory verbal comprehension.

METHOD

We use lasso regression and cross-validation to identify an optimal subset from a set of 174 pictures to be named for prediction of aphasia severity, based on data from 200 participants with left-hemisphere stroke who were quasirandomly selected to represent the full impairment scale. Data from 20 healthy controls (i.e., participant caretakers/spouses) were also analyzed. We examine interrater reliability, test-retest reliability, sensitivity and specificity to the presence of aphasia, sensitivity to therapy gains, and external validity (i.e., correlation with aphasia severity measures) for the SCANT.

RESULTS

The SCANT has extremely high interrater reliability, and it is sensitive and specific to the presence of aphasia. We demonstrate the superiority of predictions based on the SCANT over those based on the full set of naming items. We estimate a 15% reduction in power when using the SCANT score versus the full test battery's aphasia severity score as an outcome measure; for example, to maintain the same power to detect a significant group average change in aphasia severity, a study with 25 participants using the full test battery to measure treatment effectiveness would require 30 participants if the SCANT were to be used as the testing instrument instead.

CONCLUSION

We provide a linear model to convert SCANT scores to aphasia severity scores, and we identify a change score cutoff of four SCANT items to obtain a high degree of confidence based on test-retest SCANT data and the modeled relation between SCANT and aphasia severity scores.

Voice Therapy Efficacy in Pediatric Professional Voice Users With Vocal Fold Nodules: A Preliminary Study

INTRODUCTION

Vocal fold nodules are the most common diagnosis in children with dysphonia. It is also frequently seen in professional voice users who uses their voice as an occupational tool. It can be caused by excessive or hyperfunctional use of the voice leading to phonotrauma. Children who learn the Quran by heart and recite it use their voices excessively and it causes voice problems. Voice therapy can play an important role in regulating phonotraumatic behaviors and improving voice quality, thereby replacing surgical intervention in some cases or acting as a complementary therapy to improve eventual therapeutic outcomes.

OBJECTIVES

Our aim was to find the efficacy of group voice therapy compared to individual voice therapy in a group of pediatric professional voice users who go to the same religious school.

METHODS

To determine group therapy efficacy, 24 students between the age of nine and 14, were evaluated and 16 of them had vocal fold nodules. Therapy sessions started with 16 students whose ages ranged from nine to 14 with a mean of 11,3 ± 1,4 years old. They were divided into two groups: group and individual therapy groups. Treatment comprised both direct and indirect voice therapy and lasted 6 weeks. Three of the participants were dropped out due to absence. Pre- and post-therapy measures were collected from 13 participants using perceptual evaluation, videostroboscopy measures, and the pediatric voice handicap index to determine the efficacy of group voice therapy compared to individual voice therapy with a group of pediatric professional voice users with vocal fold nodules.

RESULTS

As a result of our study, eight of participants were found to have healthy vocal folds; the s/z ratio was significantly different between groups and within group therapy participants pre- and post-therapy. No significant difference was found in other parameters; except noise harmonic ratio (NHR). NHR was found significantly different between pre- and post-therapy when individual therapy and group therapy were compared. Although both treatments were shown to be beneficial in the management of vocal fold nodules, individual therapy was found to be somewhat more effective.

CONCLUSION

In pediatric voice therapy, group therapy is an effective option to reach out to more individuals with voice disorders. It can be beneficial for time management and cost effectiveness in voice therapy.

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.

Two-Year Longitudinal Evaluation of Community Aphasia Center Participation on Linguistic, Functional Communication, and Quality of Life Measures Across People With a Range of Aphasia Presentations

PURPOSE

The purpose of this study was to evaluate potential changes on a hierarchy of language tasks and measures of functional communication and quality of life in a group of people with aphasia (PWA) who attended a community aphasia center for 2 years. A secondary purpose was to determine whether there were any predictors of change.

METHOD

Twenty-seven PWA who attended Brooks Rehabilitation Aphasia Center (BRAC) were evaluated on an aphasia battery, confrontation naming, and structured discourse in addition to completing self-reported measures of functional communication and quality of life at three time points: before attending BRAC and after 1 (N = 27) and 2 (N = 20) years of BRAC participation. Twenty-six communication partners who communicated regularly with the PWA completed a questionnaire about their functional communication at the same time points. A mixed linear model was conducted for all dependent variables to determine change over time. Tau-b correlations were conducted between demographic and aphasia-related variables and difference scores for outcome measures that exhibited significant improvements.

RESULTS

At 1-year testing, significant improvements were observed on the aphasia battery, object and action naming, and all self- and communication partner-reported measures. At 2-year testing, all improvements were maintained except for the self-reported measure of functional communication. Structured discourse showed increases in average number of words, percentage of meaningful words and utterances, and efficiency of meaningful word production after 2 years. No significant correlations were observed between predictor variables and difference scores.

CONCLUSIONS

Participation in aphasia centers can result in significant changes in language, functional communication, and quality of life in people with chronic aphasia. These findings support the importance of aphasia centers in the continuum of care for PWA.

Still Searching for Understanding: The Importance of Diverse Research Designs, Methods, and Perspectives

BACKGROUND

Evidence-based medicine and evidence hierarchies have been widely adopted and have strongly influenced decision making across many fields, including clinical aphasiology. However, questions remain about the creation, usefulness, and validity of current evidence hierarchies.

AIMS

This article builds on ideas about scientific approaches and evidence originally shared by Elman (1995, 1998, 2006). This article reviews the history of evidence hierarchies and argues that improving the diversity of research designs, methods, and perspectives will improve understanding of the numerous and complex variables associated with aphasia intervention. Researchers and clinicians are encouraged to synthesize diverse types of scientific evidence. It is hoped that this article will stimulate thought and foster discussion in order to encourage high-caliber research of all types.

MAIN CONTRIBUTION

Concepts from a wide variety of fields including philosophy of science, research design and methodology, and precision medicine are brought together in an attempt to focus research on the scientific understanding of aphasia treatment effects.

CONCLUSION

It is hoped that by incorporating diverse research designs, methods, and perspectives, clinical aphasiologists will become better able to provide effective, personalized treatments, ensuring that each person with aphasia is able to improve their communication ability and quality of life.

Designing and Implementing a Community Aphasia Group: An Illustrative Case Study of the Aphasia Group of Middle Tennessee

PURPOSE

Community aphasia groups serve an important purpose in enhancing the quality of life and psychosocial well-being of individuals with chronic aphasia. Here, we describe the Aphasia Group of Middle Tennessee, a community aphasia group with a 17-year (and continuing) history, housed within Vanderbilt University Medical Center in Nashville, Tennessee.

METHOD

We describe in detail the history, philosophy, design, curriculum, and facilitation model of this group. We also present both quantitative and qualitative outcomes from group members and their loved ones.

RESULTS

Group members and their loved ones alike indicated highly positive assessments of the format and value of the Aphasia Group of Middle Tennessee.

CONCLUSION

By characterizing in detail the successful Aphasia Group of Middle Tennessee, we hope this can serve as a model for clinicians interested in starting their own community aphasia groups, in addition to reaching individuals living with chronic aphasia and their loved ones through the accessible and aphasia-friendly materials provided with this clinical focus article.

Adaptation of The Scenario Test for Greek-speaking people with aphasia: A reliability and validity study

BACKGROUND

Evidence-based assessments for people with aphasia (PWA) in Greek are predominantly impairment based. Functional communication (FC) is usually underreported and neglected by clinicians. This study explores the adaptation and psychometric testing of the Greek (GR) version of The Scenario Test. The test assesses the everyday FC of PWA in an interactive multimodal communication setting.

AIMS

To determine the reliability and validity of The Scenario Test-GR and discuss its clinical value.

METHODS & PROCEDURES

The Scenario Test-GR was administered to 54 people with chronic stroke (6+ months post-stroke): 32 PWA and 22 stroke survivors without aphasia. Participants were recruited from Greece and Cyprus. All measures were administered in an interview format. Standard psychometric criteria were applied to evaluate reliability (internal consistency, test-retest, and interrater reliability) and validity (construct and known-groups validity) of The Scenario Test-GR.

OUTCOMES & RESULTS

The Scenario Test-GR shows high levels of reliability and validity. High scores of internal consistency (Cronbach's α = 0.95), test-retest reliability (intra-class coefficients (ICC) = 0.99), and interrater reliability (ICC = 0.99) were found. Interrater agreement in scores on individual items ranged from good to excellent levels of agreement. Correlations with a tool measuring language function in aphasia, a measure of FC, two instruments examining the psychosocial impact of aphasia and a tool measuring non-verbal cognitive skills revealed good convergent validity (all ps < 0.05). Results showed good known-groups validity (Mann-Whitney U = 96.5, p < 0.001), with significantly higher scores for participants without aphasia compared with those with aphasia.

CONCLUSIONS & IMPLICATIONS

The psychometric qualities of The Scenario Test-GR support the reliability and validity of the tool for the assessment of FC in Greek-speaking PWA. The test can be used to assess multimodal FC, promote aphasia rehabilitation goal-setting at the activity and participation levels, and be used as an outcome measure of everyday communication abilities.

Naming vs. non-naming treatment in aphasia in a group setting-A randomized controlled trial

INTRODUCTION

Anomia affects numerous persons with aphasia. Treatment effects of anomia group therapy have been reported, but the evidence is not comprehensive. This study aimed to explore treatment effects of a naming treatment compared with a non-naming treatment delivered in a group setting.

METHODS

In a randomized controlled trial, 17 participants with chronic poststroke aphasia underwent group therapy, 2 hours a session, 3 times per week, for a total of 20 hours. The treatment given in the naming group was modified semantic feature analysis (SFA). Treatment content in the non-naming group comprised auditory comprehension, copying text, and reading. The primary outcome measure was accuracy in confrontation naming of participant-selected trained nouns and verbs. Generalization effects were evaluated in single-word naming, connected speech, and everyday communication.

RESULTS

Participants in both groups significantly improved their naming of trained items. There were no differences between the groups. The treatment effect did not remain at follow-up 10 weeks after therapy. No other statistically significant changes occurred in either group.

CONCLUSIONS

Group intervention can improve naming ability in individuals with chronic aphasia. However, similar treatment effects can be achieved using a non-naming treatment as using a naming treatment, such as modified SFA. Further research is warranted to identify the most important elements of anomia group therapy.

Young Adults With Acquired Brain Injury Show Longitudinal Improvements in Cognition After Intensive Cognitive Rehabilitation

PURPOSE

The aim of this study was to assess the effect of an intensive cognitive and communication rehabilitation (ICCR) program on language and other cognitive performance in young adults with acquired brain injury (ABI).

METHOD

Thirty young adults with chronic ABI participated in this study. Treatment participants (n = 22) attended ICCR 6 hours/day, 4 days/week for at least one 12-week semester. Deferred treatment/usual care control participants (n = 14) were evaluated before and after at least one 12-week semester. Pre- and postsemester standardized cognitive assessment items were assigned to subdomains. Between-groups and within-group generalized linear mixed-effects models assessed the effect of time point on overall item accuracy and differences by item subdomain. Subdomain analyses were adjusted for multiple comparisons.

RESULTS

Between-groups analyses revealed that treatment participants improved significantly faster over time than deferred treatment/usual care participants in overall item accuracy and specifically on items in the verbal expression subdomain. Investigating the three-way interaction between time point, group, and etiology revealed that the overall effects of the treatment were similar for individuals with nontraumatic and traumatic brain injuries. The treatment group showed an overall effect of treatment and significant gains over time in the verbal expression, written expression, memory, and problem solving subdomains. The control group did not significantly improve over time on overall item accuracy and showed significant subdomain-level gains in auditory comprehension, which did not survive correction.

CONCLUSIONS

Sustaining an ABI in young adulthood can significantly disrupt key developmental milestones, such as attending college and launching a career. This study provides strong evidence that integrating impairment-based retraining of language and other cognitive skills with "real-world" application in academically focused activities promotes gains in underlying cognitive processes that are important for academic success as measured by standardized assessment items. These findings may prompt a revision to the current continuum of rehabilitative care for young adults with ABI.

Transcranial Direct-Current Stimulation as an Adjunct to Verb Network Strengthening Treatment in Post-stroke Chronic Aphasia: A Double-Blinded Randomized Feasibility Study

Background

Difficulties in discourse production are common in post-stroke chronic aphasia. Previous studies have found that speech and language therapy combined with transcranial direct-current stimulation (tDCS) may improve language skills like naming and enhance aphasia treatment outcomes. However, very few studies have investigated the effect of tDCS when combined with interventions for improving higher level language skills such as the Verb Network Strengthening Treatment (VNeST).

Aims

This study aimed to determine the feasibility of anodal tDCS as an adjunct to VNeST to improve discourse production in post-stroke chronic aphasia.

Methods

Six people with post-stroke chronic aphasia took part in this double-blinded randomized feasibility study. Participants were randomly allocated to either the experimental group receiving a 6-week block of once weekly VNeST sessions combined with active tDCS over the left inferior frontal gyrus (LIFG) or a control group that received VNeST with sham stimulation. Feasibility outcomes included screening, eligibility, retention, and completion rates, and adverse events. Preliminary response to intervention was also examined using discourse production, functional communication, quality of life, psychological state, and cognition outcomes.

Results

Overall 19 individuals were screened and ten met the inclusion criteria. Six individuals provided consent and participated in the study giving a consent rate of 60%. Participant retention and completion rates were 100% and no adverse effects were reported. Exploratory analyses revealed promising changes (i.e., estimated large effect size) in discourse production measures across discourse language tasks and functional communication for the active tDCS group.

Conclusions

Our results support the feasibility of tDCS as an adjunct to VNeST. Preliminary findings provide motivation for future large-scale studies to better understand the potential of tDCS as a safe and economical tool for enhancing rehabilitation in chronic aphasia.

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.

What is Functional Communication? A Theoretical Framework for Real-World Communication Applied to Aphasia Rehabilitation

Aphasia is an impairment of language caused by acquired brain damage such as stroke or traumatic brain injury, that affects a person’s ability to communicate effectively. The aim of rehabilitation in aphasia is to improve everyday communication, improving an individual’s ability to function in their day-to-day life. For that reason, a thorough understanding of naturalistic communication and its underlying mechanisms is imperative. The field of aphasiology currently lacks an agreed, comprehensive, theoretically founded definition of communication. Instead, multiple disparate interpretations of functional communication are used. We argue that this makes it nearly impossible to validly and reliably assess a person’s communicative performance, to target this behaviour through therapy, and to measure improvements post-therapy. In this article we propose a structured, theoretical approach to defining the concept of functional communication. We argue for a view of communication as “situated language use”, borrowed from empirical psycholinguistic studies with non-brain damaged adults. This framework defines language use as: (1) interactive, (2) multimodal, and (3) contextual. Existing research on each component of the framework from non-brain damaged adults and people with aphasia is reviewed. The consequences of adopting this approach to assessment and therapy for aphasia rehabilitation are discussed. The aim of this article is to encourage a more systematic, comprehensive approach to the study and treatment of situated language use in aphasia.

Who, what, when, where, why, and how: a systematic review of the quality of post-stroke cognitive rehabilitation protocols

BACKGROUND

. Rehabilitation research findings are not routinely incorporated into clinical practice. A key barrier is the quality of reporting in the original study, including who provided the intervention, what it entailed, when and where it occurred, how patient outcomes were monitored, and why the intervention was efficacious.

OBJECTIVES

. To facilitate clinical implementation of post-stroke cognitive rehabilitation research, we undertook a review to examine the quality of intervention reporting in this literature.

METHODS

. Four databases were systematically searched, identifying 27 randomised controlled trials of post-stroke cognitive rehabilitation. The quality of intervention protocol descriptions in each study was independently rated by 2 of the authors using the 12-item Template for Intervention Description and Replication (TIDieR) checklist.

RESULTS

.Why, when, and where items were reported in more than 70% of interventions, what materials and procedures used was described in 50% to 70%, how items were described in approximately half of the interventions, and who provided interventions was reported in 22% of studies. No study addressed all 12 TIDieR items. "Active ingredients" that may further characterise an intervention and the potential mechanisms of action included restorative training, massed practice, feedback, and tailoring demands (present in approximately 50% of studies).

CONCLUSIONS

. Descriptions of intervention protocols are variable and frequently insufficient, thereby restricting the ability to understand, replicate, and implement evidence-based cognitive rehabilitation. Use of reporting checklists to address this barrier to research translation is a readily achievable and effective means to advance post-stroke care.

A Randomized Controlled Trial of the Effects of Group Conversation Treatment on Monologic Discourse in Aphasia

PURPOSE

Evidence has shown that group conversation treatment may improve communication and reduce social isolation for people with aphasia. However, little is known about the impact of conversation group treatment on measures of discourse. This project explored the impact of conversation treatment on measures of monologic discourse.

METHOD

In this randomized controlled trial, 48 participants with chronic aphasia were randomly assigned to dyadic, large group, or control conditions. Conversation group treatment was provided for 1 hr, twice per week, for 10 weeks. Discourse samples were collected and coded at pretreatment, posttreatment, and 6-week maintenance. There were three narrative tasks: (a) Comprehensive Aphasia Test (CAT) picture description, (b) Cat Rescue Picture, and (c) Cinderella retell. All narratives were coded using the percent correct information units (percent CIUs), the CAT standardized narrative analysis method, and the complete utterance (CU) method.

RESULTS

No significant changes were observed on percent CIU, which was the primary outcome measure. The treated groups demonstrated improvement on aspects of the CU method following treatment, whereas the control group did not. Significant changes were observed for other CIU measures and the CAT standardized narrative analysis in both the treated and control groups.

CONCLUSIONS

The results suggest that the CU measures were more sensitive to the effects of conversation treatment in monologic discourse compared to CIU and CAT measures. Changes were more common in absolute rather than relative values, suggesting that conversation treatment impacts the overall amount of language produced rather than efficiency of production.

Demystifying the complexity of aphasia treatment: Application of the Rehabilitation Treatment Specification System (RTSS)

A considerable body of research supports the use of behavioral communication treatment as the standard of care for aphasia. In spite of robust progress in clinical aphasiology, many questions regarding optimal care remain unanswered. One of the major challenges to progress in the field is the lack of a common framework to adequately describe individual treatments, which, if available, would allow comparisons across studies as well as improved communication among researchers, clinicians, and other stakeholders. Here, we describe how aphasia treatment approaches can be systematically characterized using the Rehabilitation Treatment Specification System (RTSS). At the core of the RTSS is a tripartite structure that focuses on targets (the behavior that is expected to change as a result of treatment), ingredients (what a clinician does to affect change in the target), and mechanism(s) of action (why a given treatment works by linking the ingredients to the target). Three separate papers in the current issue specifically describe how the RTSS can be used to describe different kinds of aphasia treatment approaches: functional approaches, cognitive-linguistic approaches, and biological approaches. It is our hope that the application of the RTSS in clinical aphasiology will improve communication in published studies, grant proposals, and in the clinical care of persons with aphasia.

Applying the Rehabilitation Treatment Specification System (RTSS) to Functional Communication Treatment Approaches for Aphasia

There are many different approaches to the rehabilitation of aphasia, a communication disorder that affects a person's understanding and expression of spoken and written language. One approach called "functional communication interventions" aims to enhance communication success as opposed to solely improve linguistic abilities. This approach encompasses many skills (e.g., gesturing) and factors (e.g., access to communication supports) that support sending and receiving messages in "real world" daily activities and environments. Functional communication treatments are highly diverse and not always well described. A framework that may provide structure to the description of functional communication interventions for aphasia is the Rehabilitation Treatment Specification System (RTSS). The RTSS was developed by an interdisciplinary research team to describe interventions across any rehabilitation discipline and in any setting or format. The RTSS uses a common language and a systematic approach to describing treatment and includes three connected elements - a single target, one or more ingredients, and a mechanism of action - that, taken together, attempt to explain how and why a treatment works. While the RTTS has been described previously within the field of speech-language pathology, it has not yet been applied to the field of aphasiology. We applied the RTSS framework to a sample of peer-reviewed studies that represent functional communication treatments, including Promoting Aphasics' Communicative Effectiveness (PACE), Modified Response Elaboration Training (M-RET), Script Training, Conversation Treatment, and Communication Partner Training. We discuss both the advantages and disadvantages of using the RTSS framework to better understand the important elements of functional communication treatment approaches for aphasia.

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.

A systematic review of maintenance following intensive therapy programs in chronic post-stroke aphasia: importance of individual response analysis

PURPOSE

Recent evidence supports the benefit of intensive aphasia intervention programs for people with chronic aphasia, yet it is unclear if all participants can expect positive outcomes and for how long therapeutic gains last.

METHODS

We systematically searched for studies investigating intensive interventions in chronic aphasia. To explore individual response rates and maintenance of therapeutic gains we carried out meta-synthesis by calculating and analysing the Standard Error of Measurement and Minimal Detectable Change metrics of six common outcome measures.

RESULTS

Forty-four studies comprising 24 experimental (13 group, 11 single-subject) and 20 non-experimental studies met our inclusion criteria (n = 670). Whereas most group studies reported statistically significant post-therapy improvement and maintenance, analysis of individual participant data (IPD, n = 393) from these studies revealed that only about a third of participants were classified as "immediate responders," of which more than a third had lost their initial immediate gains at follow-up. This pattern did not change when IPD from single-subject studies (n = 49) was added to the analysis. Thus, only 22% of all IPD receiving an intensive intervention improved significantly and maintained their therapy gains.

CONCLUSIONS

Intensive aphasia therapy is effective when measured at the group-level, but many individuals do not respond significantly to the intervention, and even fewer individuals preserve their initial gains. Group study results do not allow prediction of an individual's response to the intervention. Future research should elucidate which factors mediate positive treatment response and maintenance for an individual.Implications for rehabilitationOnly a small proportion (about one fifth in this review) of intensive aphasia treatment program participants respond and maintain their therapy gains, a fact that is obscured by traditional p-value group analysis.A simple clinical decision-making method is presented for evaluating individual therapy gains and their maintenance.For some immediate treatment responders (about one third in this review), gains from intensive therapy programs are unlikely to be maintained in the long-term without additional, ongoing practice.Clinicians should consider the possibility of individual clients losing some of their therapy gains and take proactive steps to support long-term maintenance.

Language treatment effects on communicative abilities and working memory in Korean-speaking agrammatic Broca's aphasia caused by moyamoya disease: Phase II evidence from a case study

The present study reports on the language treatment outcomes from sentence- and story-level linguistic facilitation and its generalization effect on communicative abilities, working memory, and sentence processing in the case of an adult with Moyamoya Disease (MMD). After treatment,the patient's overall performance, including the Aphasia Quotient, and sentence processing ability as measured by language testing, were improved. Furthermore, the treatment effects were generalizable to working memory abilities. Our case study conveys clinically meaningful implications since it is the first report on the effects of language treatment on linguistic and cognitive domains for an individual with MMD-induced agrammatic Broca's aphasia.

Longer-term health and social care strategies for stroke survivors and their carers: the LoTS2Care research programme including cluster feasibility RCT

Background

It is reported that the longer-term outcomes for stroke survivors are poor, with a range of unmet needs identified.

Objectives

The aims were to develop and test a longer-term stroke care strategy focused on improving the quality of life of stroke survivors and their carers by addressing unmet needs, and maintenance and enhancement of participation (i.e. involvement in life situations).

Design

Five overlapping workstreams were undertaken – (1) refinement of content by semistructured interviews with stroke survivors and their carers and by a review of the literature to inform content and delivery of the care strategy; (2) exploration of service models by national survey and focus groups with purposely selected services; (3) intervention development by interaction with a reference group of stroke survivors, carers, and health and social care professionals; (4) refinement and pilot implementation of the developed intervention in three stroke services (case studies); and (5) a cluster randomised controlled feasibility trial in 10 stroke services across England and Wales.

Setting

The intervention development work and feasibility trial were in stroke services (inclusive of primary, secondary, community and social care provision) across England and Wales.

Participants

Participants were stroke survivors resident in the community and their carers, and health and social care professionals in the included stroke services.

Data sources

Interviews with 28 stroke survivors and their carers at least 9 months post stroke ascertained their needs and the barriers to and facilitators of addressing those needs. Additional literature reviews identified 23 needs. No evidence-based interventions to address these needs were reported; self-management was highlighted as a possible delivery mechanism. In workstream 2, a national survey revealed that the most common model of stroke service provision was care up to 12 months post stroke, reported by 46 (40%) services. Thirty-five (30%) services provided care up to 6 months post stroke and 35 (30%) provided care beyond 12 months, thus identifying 6 months post stroke as an appropriate delivery point for a new intervention. Through focus groups in a range of services, stroke survivors’ perceived unmet needs and the barriers to and enablers of service provision were identified.

Intervention

Using information obtained in workstreams 1 and 2 and working closely with a stakeholder reference group, we developed an intervention based on the unmet needs prioritised by stroke survivors and their carers (workstream 3). In workstream 4, action groups (clinicians, stroke survivors and researchers) were established in three stroke services that led implementation in their service and contributed to the iterative refinement of the intervention, associated training programme and implementation materials. The intervention (called New Start) was delivered at 6 months post stroke. Key components were problem-solving self-management with survivors and carers, help with obtaining usable information, and helping survivors and their carers build sustainable, flexible support networks.

Results

A cluster randomised feasibility trial (workstream 5) was successfully implemented in 10 stroke services across England and Wales, with associated process and health economic evaluations. Five services were randomised to provide New Start, while five continued with usual care; 269 participants were recruited. Progression criteria – in terms of our pre-determined (red, amber, green) criteria for progress to a full trial: target stroke survivor recruitment rates were achieved, on average, across sites (24.1 per site over 6 months, green); 216 (80.3%) registered stroke survivors returned follow-up questionnaires at 9 months (84.1% in the intervention arm and 75.8% in the usual care arm, green); according to data reported by sites, overall, 95.2% of registered stroke survivors were offered at least one session of the intervention (green); all five intervention sites had at least two facilitators deemed competent, delivered the New Start intervention and provided it to stroke survivors (green). However, at some sites, there were concerns regarding the number of stroke survivors being offered, accepting and receiving the intervention. Only small differences in outcomes and costs were observed between the New Start and usual care groups, and considerable uncertainty around the cost-effectiveness remains.

Conclusions

We report a complex programme of work that has described the longer-term needs of stroke survivors and highlighted evidence and service gaps. Working closely with stroke survivors, an intervention was developed that has been refined in three services and feasibility tested in a cluster randomised controlled trial. Further refinement of the target population and optimisation of the intervention materials is required prior to a full randomised controlled trial evaluation.

Future work

Optimisation of the intervention, and clearer specification of recipients, are required prior to a full trial evaluation.

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

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

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

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

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

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

Patterns of Conversation Trouble Source and Repair as Indices of Improved Conversation in Aphasia: A Multiple-Case Study Using Conversation Analysis

Purpose Social approaches to intervention for aphasia are being increasingly employed to address the functional communication barriers experienced by persons with aphasia. One specific approach is the use of conversation-based treatment in both group and two-person dyads. Although there are several methods to measure improvement for stimulation and cognitive neurolinguistic approaches, researchers have consistently indicated a need for outcome measures that can objectively demonstrate improved communication following conversation treatment. This study aims to demonstrate the utility for examining the patterns of conversation trouble source and repair as indices for improved communication as a positive response to intervention. Method The conversations of 20 consecutive participants, before and after 3 months, or 40 hr, of group and individual conversation-based treatment, were transcribed using conventions of conversation analysis, and sociolinguistic discourse analysis was applied. Measures of trouble source and repair were aggregated and subjected to statistical analysis. Results Persons with aphasia demonstrated statistically significant improvement in patterns of conversation trouble source and repair posttreatment for the rate of conversation trouble source and the length of repair. However, measures of self-initiation and self-completion of repair did not reach significance. Conclusion The study indicates that, following conversation-based treatment, the conversations of persons with aphasias were more efficient, experiencing fewer trouble sources and shorter repair sequences. These findings suggest that measures of conversation for the rate of trouble source and length of the repair sequence are valid indices of improved conversation.

Correlation Between Speech Repetition Function and the Arcuate Fasciculus in the Dominant Hemisphere Detected by Diffusion Tensor Imaging Tractography in Stroke Patients with Aphasia

Background

Repetition disorder can be used as an important criterion for aphasia classification, and damaged arcuate fasciculus in the dominate hemisphere has been reported to be closely related to repetition disorder, but the underlying neurological mechanism remains unclear.

Material/Methods

Fifteen stroke patients with poststroke aphasia and 9 healthy controls were included in the study. The value of fractional anisotropy (FA) in the dominate arcuate fasciculus in stroke patients and healthy controls were measured using DTI. We also assessed their repetition dysfunction with the Aphasia Battery of Chinese (ABC) assessment and calculated the correlation between the FA values in the dominate arcuate fasciculus and ABC scores of word repetition and sentence repetition.

Results

There was a moderate correlation between the total score of repetition evaluation and the FA value of injured arcuate fasciculus in the dominant hemisphere (r=0.551, P=0.033). We found no correlation between the score of word repetition and the FA value of injured arcuate fasciculus in the dominant hemisphere (r=0.330, P=0.230), but there was a strong correlation between the score of sentence repetition and the FA value of injured arcuate fasciculus in the dominant hemisphere (r=0.795, P≤0.001).

Conclusions

We found that unintegrated left arcuate fasciculus might be related to the repetition dysfunction after stroke, especially sentence repetition deficit, which suggests that sentence repetition evaluation could be used to indicate the integrity of the arcuate fasciculus in the dominant hemisphere after stroke.

A randomised trial of social support group intervention for people with aphasia: A Novel application of virtual reality

About a third of strokes cause aphasia, or language loss, with profound consequences for the person's social participation and quality of life. These problems may be mitigated by group social support. But this intervention is not available to all individuals. This study investigated whether it is feasible to deliver group social support to people with aphasia via a multi-user, virtual reality platform. It also explored the indicative effects of intervention and the costs. Intervention aimed to promote wellbeing and communicative success. It enabled participants to form new social connections and share experiences of living with aphasia. It comprised 14 sessions delivered over 6 months and was led by community based co-ordinators and volunteers. Feasibility measures comprised: recruitment and retention rates, compliance with intervention and assessment of treatment fidelity. Effects of intervention were explored using a waitlist randomised controlled design, with outcome measures of wellbeing, communication, social connectedness and quality of life. Two intervention groups were randomised to an immediate condition and two were randomised to a delayed condition. The main analysis explored scores on the measures between two time points, between which those in the immediate condition had received intervention, but those in the delayed group had not (yet). A comprehensive approach to economic data collection ensured that all costs of treatment delivery were recorded. Feasibility findings showed that the recruitment target was met (N = 34) and 85.3% (29/34) of participants completed intervention. All groups ran the 14 sessions as planned, and participants attended a mean of 11.4 sessions (s.d. 2.8), which was 81.6% of the intended dose. Fidelity checking showed minimal drift from the manualised intervention. No significant change was observed on any of the outcome measures, although the study was not powered to detect these. Costs varied across the four groups, from £7,483 - £12,562 British Pounds Sterling ($10,972 - $18,419 US dollars), depending on travel costs, the relative contributions of volunteers and the number of hardware loans that were needed. The results suggest that a larger trial of remote group support, using virtual reality, would be merited. However the treatment content and regime, and the selection of outcome measures should be reviewed before conducting the trial.

Multisensory cueing facilitates naming in aphasia

BACKGROUND

Impaired naming is a ubiquitous symptom in all types of aphasia, which often adversely impacts independence, quality of life, and recovery of affected individuals. Previous research has demonstrated that naming can be facilitated by phonological and semantic cueing strategies that are largely incorporated into the treatment of anomic disturbances. Beneficial effects of cueing, whereby naming becomes faster and more accurate, are often attributed to the priming mechanisms occurring within the distributed language network.

OBJECTIVE

We proposed and explored two novel cueing techniques: (1) Silent Visuomotor Cues (SVC), which provided articulatory information of target words presented in the form of silent videos, and (2) Semantic Auditory Cues (SAC), which consisted of acoustic information semantically relevant to target words (ringing for "telephone"). Grounded in neurophysiological evidence, we hypothesized that both SVC and SAC might aid communicative effectiveness possibly by triggering activity in perceptual and semantic language regions, respectively.

METHODS

Ten participants with chronic non-fluent aphasia were recruited for a longitudinal clinical intervention. Participants were split into dyads (i.e., five pairs of two participants) and required to engage in a turn-based peer-to-peer language game using the Rehabilitation Gaming System for aphasia (RGSa). The objective of the RGSa sessions was to practice communicative acts, such as making a request. We administered SVCs and SACs in a pseudorandomized manner at the moment when the active player selected the object to be requested from the interlocutor. For the analysis, we compared the times from selection to the reception of the desired object between cued and non-cued trials.

RESULTS

Naming accuracy, as measured by a standard clinical scale, significantly improved for all stimuli at each evaluation point, including the follow-up. Moreover, the results yielded beneficial effects of both SVC and SAC cues on word naming, especially at the early intervention sessions when the exposure to the target lexicon was infrequent.

CONCLUSIONS

This study supports the efficacy of the proposed cueing strategies which could be integrated into the clinic or mobile technology to aid naming even at the chronic stages of aphasia. These findings are consistent with sensorimotor accounts of language processing, suggesting a coupling between language, motor, and semantic brain regions.

Follow-Up in Aphasia Caused by Acute Stroke in a Prospective, Randomized, Clinical, and Experimental Controlled Noninvasive Study With an iPad-Based App (Neolexon®): Study Protocol of the Lexi Study

Rationale: Treatment of aphasia is still challenging for clinicians and patients. So far, there is proven evidence for "face-to-face" speech therapy. However, the digital age potentially offers new and complementary strategies that may add to treatment outcome in a cost-effective way. Neolexon® is a commercial tablet-based software for treatment of aphasia, which can be applied with the help of a therapist or as self-training by the patient. Aims and hypothesis: In the Lexi study, we aim to determine whether treatment with Neolexon® is superior to standard therapy in acute post-stroke aphasia. Sample size estimates: A sample size of 180 patients, 90 for each group, will be included with an assumed dropout rate of ~20%. Methods and design: Prospective, randomized, parallel group, open-label, blinded-endpoint clinical, and experimental controlled non-invasive trial (PROBE). Adult German native speakers with acute aphasia after stroke are included. Computer-generated, blocked, and stratified randomization by aphasia severity will assign patients to one of two groups: 4 weeks of either standard logopedic speech therapy or logopedic speech therapy with the app version of Neolexon®. Both groups will be instructed in self-training: the frequency and duration of self-training will be documented. Screening for aphasia will be performed using the Language Screening Test (LAST). The severity of aphasia in general and in subitems will be assessed using the Bielefelder Aphasie Screening (BIAS) and the Aphasia Check List (ACL). Follow-up will be assessed after 3 months. Study outcomes: Based on the consensus in our study team, we considered a 10% mean difference in the change of percentile rank (PR) of BIAS to be a minimal and clinically important difference. The primary endpoint is defined as a significant difference in BIAS comparing the two groups. Differences in quality of life, Beck Depression Inventory (BDI), and modified Ranking Scale (mRS) will be evaluated as secondary outcome parameters. Discussion: This trial will determine whether speech therapy with the use of Neolexon® is superior to standard logopedic therapy. Subgroups with the greatest response to Neolexon® will be described. The trial was prospectively registered on the "EU Clinical Trials Register" (NCT04080817).

Clinical Practice Recommendations for Improving Life Participation for People With Aphasia in Long-Term Care

Purpose

The purpose of this clinical focus article is to present an overview of the Life Participation Approach to Aphasia as it relates to issues in long-term care (LTC) and provide practical recommendations for implementing the approach in this setting. The Framework for Living With Aphasia is used as a guide to (a) highlight specific challenges to life participation for residents with aphasia in LTC and (b) propose clinical tools that might help clinicians move through the therapeutic process when implementing the Life Participation Approach to Aphasia.

Recommendations

Clinicians in LTC facilities have the responsibility of delivering services that have a positive impact on communication, social relationships, emotional health, and quality of life. Clinical tools and approaches most appropriate for LTC settings are identified that help to address these goals. Approaches are discussed across several stages representing the therapeutic process, which is ultimately aimed at moving a resident toward recovery and increased independence. Case demonstrations are provided to illustrate approaches.

Treatment Fidelity Procedures for an Aphasia Intervention Within a Randomized Controlled Trial: Design, Feasibility, and Results

Purpose This study reports on the treatment fidelity procedures implemented during a 5-year randomized controlled trial comparing intensive and distributed comprehensive aphasia therapy. Specifically, the results of 1 treatment, verb network strengthening treatment (VNeST), are examined. Method Eight participants were recruited for each of 7 consecutive cohorts for a total of 56 participants. Participants completed 60 hr of aphasia therapy, including 15 hr of VNeST. Two experienced speech-language pathologists delivered the treatment. To promote treatment fidelity, the study team developed a detailed manual of procedures and fidelity checklists, completed role plays to standardize treatment administration, and video-recorded all treatment sessions for review. To assess protocol adherence during treatment delivery, trained research assistants not involved in the treatment reviewed video recordings of a subset of randomly selected VNeST treatment sessions and completed the fidelity checklists. This process was completed for 32 participants representing 2 early cohorts and 2 later cohorts, which allowed for measurement of protocol adherence over time. Percent accuracy of protocol adherence was calculated across clinicians, cohorts, and study condition (intensive vs. distributed therapy). Results The fidelity procedures were sufficient to promote and verify a high level of adherence to the treatment protocol across clinicians, cohorts, and study condition. Conclusion Treatment fidelity strategies and monitoring are feasible when incorporated into the study design. Treatment fidelity monitoring should be completed at regular intervals during the course of a study to ensure that high levels of protocol adherence are maintained over time and across conditions.

Facilitator Behaviors Leading to Engagement and Disengagement in Aphasia Conversation Groups

Purpose Researchers have identified features of successful aphasia conversation groups and clinician behaviors leading to engagement and group cohesion. There has been less focus in the literature on facilitator behaviors that hinder participation or result in disengagement. This study aims to explore the behaviors of graduate student facilitators that contribute to and detract from engagement in aphasia conversation groups. Method Data were drawn from 4 conversation group sessions from 2 different university settings. Groups included 1 graduate student facilitator and 3 or more persons with aphasia. Sociolinguistic discourse analysis was applied to transcripts of group sessions. Results Three broad patterns detailing facilitator behaviors were identified. Several facilitator actions contributing to engagement were noted, including strategic use of topic elicitors, multimodal communication supports, and techniques to avoid interactional asymmetry. Behaviors associated with participant disengagement were also noted across sessions, including restricted discourse behaviors and difficulty managing the competing needs of participants. Engagement and disengagement were the product of several coordinating actions of the facilitator and group members that together influenced participation in conversation. Conclusion Results suggest that novice facilitators exhibit behaviors that contribute to and detract from participant engagement in aphasia conversation groups. Findings, discussed within the context of the literature on well-managed groups, highlight the skill required in managing the needs of participants with aphasia and knowing how and when to employ clinician-led strategies.

E-Learning course for nurses on pain assessment in patients unable to self-report

Public hospitals in Catalonia, Spain, have recommended assessing pain in non-communicative inpatients by means of the Spanish version of the Pain Assessment in Advanced Dementia scale (PAINAD-Sp) since 2010; a modification for patients with neurologic disorders and cancer, PAINAD-Sp_Hosp, has also been validated. However, nurses are not routinely trained in the use of the scales. The aim of this study was to assess knowledge on pain assessment in nurses following an online training course. We surveyed participants prior to the course to determine baseline knowledge of pain and pain assessment. Course material included conceptual content on pain and practical videos demonstrating the scoring system for the PAINAD-Sp_Hosp scale. After completing the course, participants took a multiple choice quiz to test understanding of course content and a satisfaction survey to determine acceptability. Of the 836 nurses invited, 401 participated in the training course; 37.7% reported having no previous specific training on pain, and just 32.2% used the PAINAD-Sp scale regularly. Following the course, virtually all (99%) of the participants passed the quiz. Overall satisfaction among nurses with regard to the training received was 8.6/10. Thus, the e-learning course was effective and acceptable for training nurses on pain assessment using validated tools.

An Exploration of the Impact of Group Treatment for Aphasia on Connected Speech

OBJECTIVE

Group treatment enables people with aphasia to practise communication skills outside the typical clinician-patient dyad. While there is evidence that this treatment format can improve participation in everyday communication, there is little evidence it impacts linguistic abilities. This project aimed to investigate the effects of 'typical' group treatment on the communication skills of people with aphasia with a focus on word retrieval in discourse.

METHODS

Three people with aphasia took part in a 6-week group therapy programme. Each week focused on a different topic, and three topics also received a home programme targeting word retrieval. The six treated topics were compared with two control topics, with regard to language production in connected speech. Semistructured interviews were collected twice prior to treatment and twice following the treatment and analysed using (a) word counts; (b) the profile of word errors and retrieval in speech; (c) a measure of propositional idea density, and (d) perceptual discourse ratings.

RESULTS

Two participants showed no significant improvements; one participant showed significant improvement on discourse ratings.

CONCLUSIONS

This study provides limited support for group treatment, leading to improved communication as measured by semistructured interviews, even when supplemented with a home programme. We suggest that either group treatment, as implemented here, was not an effective approach for improving communication for our participants and/or that outcome measurement was limited by difficulty assessing changes in connected speech.

Efficacy of Group Conversation Intervention in Individuals with Severe Profiles of Aphasia

An estimated 390,000 to 520,000 individuals with severe aphasia (IWSA) currently live in the United States. IWSA experience profound social isolation, which is associated with a wide range of negative health outcomes, including mortality. Treatments for severe aphasia frequently focus on compensatory communication approaches or a discrete communication act rather than on participation-based treatment. The purpose of this study was to determine whether IWSA demonstrated improved performance on standardized language measures, patient-reported outcome measures, and connected speech samples as a result of client-centered conversation group treatment. Results of assessments conducted at pretreatment, posttreatment, and maintenance intervals were variable across participants. All participants demonstrated improvement in at least one of the outcome measures considered. Importantly, none of these measures fully captured how IWSA were able to convey their thoughts in supported conversation. The results lend support for the use of conversation treatment for, and for further study in, this subpopulation of individuals with aphasia.

The impact of the telerehabilitation group aphasia intervention and networking programme on communication, participation, and quality of life in people with aphasia

Purpose: Aphasia group therapy can result in improvements in communication, participation and quality of life (QOL). However, evidence for aphasia group interventions with combined aims across the International Classification of Functioning, Disability and Health (ICF) is limited. TeleGAIN is a holistic aphasia group intervention that can be delivered via telepractice. This study builds on prior pilot work and addresses the need for additional research into the effectiveness of TeleGAIN. The aim of this study was to describe changes in aphasia severity, communication related QOL and participation, for people with chronic aphasia following TeleGAIN. Method: Nineteen participants with aphasia were assessed on a range of outcome measures before and after a twelve-week block of TeleGAIN delivered via web based videoconferencing. Treatment provided opportunities to participate in conversation, engage with others with aphasia and complete functional communication activities. Result: Statistical analyses revealed statistically significant improvements in communication related QOL, increased engagement in communicative activities, and decreased aphasia severity. Conclusion: Results from this study suggest that the online delivery of a multi-purpose group intervention for people with aphasia can result in improved communication, communicative participation, and QOL. It also highlights the potential for intervention provided via telepractice to offer an alternative to face-to-face services.

Clinical Outcomes Following Language-Specific Attention Treatment Versus Direct Attention Training for Aphasia: A Comparative Effectiveness Study

Purpose This study was conducted to examine the comparative effectiveness of 2 different approaches, 1 domain-specific and the other domain-general, to language and attention rehabilitation in participants with stroke-induced aphasia. The domain-specific treatment consisted of language-specific attention treatment (L-SAT), and the domain-general treatment consisted of direct attention training (DAT) using the computerized exercises included in Attention Process Training-3 (Sohlberg & Mateer, 2010). Method Four individuals with mild-moderate aphasia participated in this study. A randomized controlled cross-over single-subject design was used to assess the effectiveness of the 2 treatments administered in this study. Treatment outcomes were evaluated in terms of participants' task performance for each program, standardized language and attention measures, tests of functional abilities, and patient-reported outcomes. Results Visual comparisons demonstrated linear improvements following L-SAT and variable patterns following DAT. Omnibus effect sizes were statistically significant for 9 of the 13 L-SAT tasks. The weighted standardized effect sizes for posttreatment changes following L-SAT ranged from small to large, with the exception of 1 task. The average group gain following DAT was 5%. The Western Aphasia Battery-Revised Aphasia Quotients (Kertesz, 2007) demonstrated reliable improvements for 3 of the 4 participants following L-SAT, whereas only 1 of the participants improved reliably following DAT. The margins of improvements in functional language were substantially larger following L-SAT than DAT. Performance on the Test of Everyday Attention improved significantly for 2 participants following L-SAT and for 1 participant following DAT on selected Test of Everyday Attention (Robertson, Ward, Ridgeway, & Nimmo-Smith, 1994) subtests. Patient-reported outcomes for communication and attention following treatment favored L-SAT compared to DAT. Conclusions The results support the view that attention is allocated in ways that are particular to specific tasks rather than as a general resource that is allocated equivalently to all processing tasks. Domain-specific treatment for language deficits due to attentional impairment appears to be a suitable, if not preferable, approach for aphasia rehabilitation.

Benchmarks of Significant Change After Aphasia Rehabilitation

OBJECTIVE

To establish benchmarks of significant change for aphasia rehabilitation outcome measures (ie, Western Aphasia Battery-Aphasia Quotient [WAB-AQ], Communicative Effectiveness Index [CETI], Boston Naming Test [BNT]) and assess if those benchmarks significantly differ across subgroups (ie, time post onset, dose frequency, treatment type).

DATA SOURCES

A comprehensive literature search of 12 databases, reference lists of previous reviews, and evidence-based practice materials was conducted.

STUDY SELECTION

Randomized controlled trials, quasi-experimental studies, single-subject design, and case studies that used a standardized outcome measure to assess change were included. Titles and full-text articles were screened using a dual review process. Seventy-eight studies met criteria for inclusion.

DATA EXTRACTION

Data were extracted independently, and 25% of extractions were checked for reliability. All included studies were assigned quality indicator ratings and an evidence level.

DATA SYNTHESIS

Random-effects meta-analyses were conducted separately for each study design group (ie, within-/between-group comparisons). For within-group designs, the summary effect size after aphasia rehabilitation was 5.03 points (95% confidence interval, 3.95-6.10, P<.001) on the WAB-AQ, 10.37 points (6.08-14.66, P<.001) on the CETI, and 3.30 points (2.43-4.18, P<.001) on the BNT. For between-group designs, the summary effect size was 5.05 points (1.64-8.46, P=.004) on the WAB-AQ and 0.55 points (-1.33 to 2.43, P=.564) on the BNT, the latter of which was not significant. Subgroup analyses for the within-group designs showed no significant differences in the summary effect size as a function of dose frequency or treatment type.

CONCLUSIONS

This study established benchmarks of significant change on 3 standardized outcome measures used in aphasia rehabilitation.

Two to Tango or the More the Merrier? A Randomized Controlled Trial of the Effects of Group Size in Aphasia Conversation Treatment on Standardized Tests

Purpose Group conversation treatment has the potential to improve communication and reduce social isolation for people with aphasia. This project examined how 2 conflicting hypotheses-treatment dosage and group dynamics-affect treatment outcomes. Method Forty-eight participants with chronic aphasia were randomly assigned to either a dyad, a large group, or a delayed control group. Conversation group treatment was provided for an hour, twice per week, for 10 weeks. Individual goals were developed by each participant and addressed in the context of thematically oriented conversation treatment. Standardized testing across language domains was completed pretreatment (Time 1), posttreatment (Time 2), at a 6-week maintenance point (Time 3), and at 11-month follow-up for the experimental groups. Results Treatment groups showed greater changes on standardized measures than the control group posttreatment. Dyads showed the most changes on measures of language impairment, whereas changes on the self-reported functional communication measure (Aphasia Communication Outcome Measure) and connected speech task only showed significant changes in the large group. Conclusions This randomized controlled trial on conversation treatment indicated that both treatment groups-but not the delayed control group-showed significant changes on standardized tests. Hence, conversation treatment is associated with changes in measures of language impairment and quality of life. Dyads showed the most changes on measures of language impairment, whereas changes on the functional communication measure (Aphasia Communication Outcome Measure) and discourse production only showed significant changes in the large group. Thus, group size may be associated with effects on different types of outcome measures.

The development and feasibility of an online aphasia group intervention and networking program - TeleGAIN

PURPOSE

Aphasia group therapy offers many benefits, however people with aphasia report difficulty accessing groups and speech-language pathologists are faced with many challenges in providing aphasia group therapy. Telerehabilitation may offer an alternative service delivery option. An online aphasia group therapy program - Telerehabilitation Group Aphasia Intervention and Networking (TeleGAIN) - has been developed according to the guidelines of the Medical Research Council (MRC) framework for complex interventions. The purpose of this paper is to describe the development of TeleGAIN and the results of a pilot trial to determine feasibility and acceptability.

METHOD

The development of TeleGAIN was informed through literature reviews in relevant topic areas, consideration of expert opinion and application of the social cognitive theory. TeleGAIN was then modelled through a feasibility pilot trial with four people with aphasia.

RESULT

TeleGAIN appeared to be feasible and acceptable to participants and able to be implemented as planned. Participant satisfaction with treatment was high and results suggested some potential for improvements in language functioning and communication-related quality of life.

CONCLUSION

TeleGAIN appeared to be feasible and acceptable, however the study highlighted issues related to technology, clinical implementation and participant-specific factors that should be addressed prior to a larger trial.

Communicative Accessibility in Aphasia: An Investigation of the Interactional Context of Long-Term Care Facilities

PURPOSE

The purpose of this study was to examine the ability of persons with aphasia to access interaction and be included in social encounters in long-term care facilities (LTCFs).

METHOD

Four persons with aphasia were the focus of this investigation. A qualitative research approach using ethnographic methods was used to conduct participant observation, semistructured interviews, and artifact analysis. Expanded field notes from observations, transcribed interviews, and artifacts were then coded to identify patterns in the data.

RESULTS

The interactional context of LTCFs negatively influenced the ability of persons with aphasia to communicate with others and develop meaningful relationships. Three major themes emerged from the data detailing the contextual elements leading to communication accessibility and inclusion: (a) lack of support, (b) social hierarchy, and (c) focus on performance.

CONCLUSIONS

Findings highlighted several barriers in LTCFs that worked to discourage persons with aphasia from living social and expressive lives. Specific obstacles included a misunderstanding of aphasia and its influence on communicative exchanges and performance-oriented environment that overlooked psychosocial needs. Speech-language pathologists have an important role for advocacy in LTCFs. Clinical implications for assessment and treatment in institutions are discussed.

Validation of the Spanish Version of the Pain Assessment in Advanced Dementia Scale (PAINAD-Sp) in Hospitalized Patients with Neurologic Disorders and Oncologic Patients Unable to Self-Report Their Pain

BACKGROUND

Pain has a significant impact on hospitalized patients and is a quality indicator for nursing care. The Pain Assessment in Advanced Dementia (PAINAD) scale measures pain in people with communication disorders and advanced dementia, but it has not been validated in any other population.

AIMS

The aim of this study was to validate the Spanish version (PAINAD-Sp) in hospitalized patients with neurologic disorders and in end-of-life cancer patients with difficulty self-reporting.

DESIGN

The study had two phases: (1) analysis of the content by a committee of experts and (2) a cross-sectional study.

SETTINGS

We collected phase 2 data from January 2017 to December 2017 in four hospitals in Barcelona: Hospital Germans Trias i Pujol, Institut Català d'Oncologia, Hospital Vall d'Hebron, and Hospital de Bellvitge.

PARTICIPANTS/SUBJECTS

We included all adults who had either a neurological disorder affecting language or an oncological disease with an end-of-life prognosis and difficulty self-reporting pain. We excluded patients with a diagnosis of dementia.

METHODS

The cross-sectional study included 325 patients who were simultaneously evaluated by two observers both at rest and in movement. We analyzed psychometric properties in terms of construct validity, reliability, and sensitivity to change.

RESULTS

We obtained Cronbach α > .70 in both situations and an inter-rater reliability of 0.80. Confirmatory factor analysis indicated that the model adjusted adequately to a unidimensional structure. In terms of sensitivity to change, the mean difference was greater in movement than at rest (difference in means was 1.15).

CONCLUSIONS

The PAINAD-Sp_Hosp scale had good psychometric qualities in terms of validity and reliability in neurology and oncology patients unable to self-report pain.

Use of mobile applications in post-stroke rehabilitation: a systematic review

OBJECTIVE

Information technology and mobile devices are potentially beneficial and useful in the management of patients who have had stroke, including recognition, translation, assessment, and rehabilitation. The objective of this study was to determine the effectiveness of mobile applications in the rehabilitation of stroke survivors.

METHODS

A literature search appraising the effectiveness of mobile applications in the rehabilitation of stroke survivors was performed on PubMed, Embase, Science Citation Index Expanded-SCIE, and EBSCO-CINAHL from their inception until May 28th, 2017. Two reviewers independently screened the literature according to eligibility criteria, evaluated study quality, and collected data from the articles included.

RESULTS

Of the 3574 articles screened, 12 studies met the eligibility criteria of the systematic review. Of these, 2 studies were randomized controlled trials and the remaining 10 were before-after studies, of which only 2 had control groups. The mobile applications encompassed 5 rehabilitation areas, 5 in physical function, 4 in language function, 2 in cognitive function, and 1 risk factor reduction. Of these 12 studies, 9 reported significant improvements in function, while in 3 studies the descriptive statistics indicated favorable changes after intervention.

CONCLUSIONS

Although the use of mobile applications in the rehabilitation of stroke survivors was effective, it is clear from this systematic review that more research is needed to verify their effectiveness.
