ABSTRACT

PURPOSE: To identify similarities and differences in factors affecting activity engagement between adults with stroke who are more and less sedentary. MATERIALS AND METHODS: Data were pooled from two studies of adults with stroke (N = 36). Sedentary time was measured activPAL micro3. Participants completed activPAL interviews, which were analyzed using framework analysis. Participants were stratified into more and less sedentary groups based on activPAL data. Between-group similarities and differences were identified. RESULTS: Adults with stroke (mean [SD] age = 65.8 [13.6] years, stroke chronicity = 40.5 [SD = 38.3] months, 36.1% female) were more sedentary (785.5 [64.7] sedentary minutes/day) and less sedentary (583.6 [87.4] sedentary minutes/day). Those who were more sedentary: engaged in basic activities of daily living, avoided activities, received assistance from other people, and did not use strategies to overcome barriers. Those who were less sedentary: engaged in instrumental and community activities, embraced new strategies, did activities with other people, and used strategies to overcome environmental barriers. CONCLUSIONS: Factors affecting activity engagement differed between people who are more and less sedentary. Interventions that aim to reduce post-stroke sedentary behavior should consider the: (1) types of activities, (2) role of other people, and (2) application of strategies to overcome activity and environment-related barriers.


People with lower levels of post-stroke sedentary behavior engaged in instrumental and community activities, relative to those with higher levels who primarily engaged in basic activities of daily living.Applying models of social support that emphasize doing with rather than doing for may be important for facilitating non-sedentary lifestyles.Facilitating the use of strategies to overcome environmental barriers to activities may be an important aspect of facilitating non-sedentary lifestyles.

ABSTRACT

BACKGROUND: Rest-activity rhythm (RAR) is a modifiable behavioral factor associated with affect and cognition. Identifying RAR characteristics associated with affect and cognition among stroke survivors provides insight into preventing poststroke affective and cognitive impairment. OBJECTIVE: To examine the associations of RAR characteristics with affect and cognition among community-dwelling stroke survivors. METHODS: Forty participants with mild stroke (mean age = 52.8; 42.5% female; 55% White) reported their affect and cognitive complaints using ecological momentary assessment and wore an accelerometer for 7 consecutive days and completed the National Institutes of Health Toolbox Cognition Battery. RAR characteristics were extracted using parametric and non-parametric approaches. Multivariable linear regressions were used to identify RAR characteristics associated with affect and cognition. RESULTS: Later onset of rest (B = 0.45; P = .008) and activity (B = 0.36; P = .041) were positively associated with depressed affect. These associations were reversed for cheerful effect (rest onset: B = -0.42; P = .017; activity onset: B = -0.39; P = .033). Cheerful affect was also positively associated with relative amplitude (ie, distinctions in activity levels between rest and activity; B = .39; P = .030). Intra-daily variability (ie, RAR fragmentation; B = 0.35; P = .042) and later onset of activity (B = .36; P = .048) were positively associated with cognitive complaints. Less erratic RAR was positively associated with fluid cognition (B = 0.29; P = .036); RAR fragmentation was positively associated with crystallized cognition (B = 0.39; P = .015). CONCLUSIONS: We identified RAR correlates of affect and cognition among stroke survivors, highlighting the value of managing RAR and sleep in stroke rehabilitation. Future studies should test whether advancing the onset of rest and activity, promoting a regular active lifestyle, and improving rest and sleep in the nighttime protect stroke survivors from affective and cognitive impairment.

ABSTRACT

PURPOSE: Strategy training is a rehabilitation intervention that aims to enhance problem-solving skills with respect to daily activity-related challenges and has achieved favorable results in Western countries. This study explored the perspectives of individuals with acquired brain injury (ABI) in Taiwan who received strategy training. MATERIALS AND METHODS: Semi-structured interviews with community-dwelling adults with ABI were conducted, and reflective memos made by research team members were recorded. Interviews and memos were analyzed through thematic analysis. RESULTS: This study included 55 participants. The analysis of the participants' interview responses and memos yielded nine themes under three categories: 1) expectations regarding strategy training, 2) perceived benefits of strategy training, and 3) barriers affecting the process and outcomes of strategy training. CONCLUSIONS: All the participants endorsed strategy training through different gains. Most participants' expectations before the intervention were uncertain. Including family members into the strategy training is of key importance for a successfulness of their goals. The participants' experiences about strategy training were affected by various barriers (i.e., health and medical problems, the physical environment, and natural events). Clinicians and researchers should consider these expectations, benefits, and barriers when studying and implementing strategy training in non-Western contexts.IMPLICATIONS FOR REHABILITATIONStrategy training provides clients the opportunity to actively engage in their own goal setting and decision making.Strategy training increases the client's confidence in their ability to participate in the community, communicate, and perform daily living and physical activities.Therapists should consider the health conditions and physical environment of clients when helping them set goals and before facilitating their engagement in the community.Taiwanese family members play a crucial role in supporting acquired brain injury survivors in strategy training.

ABSTRACT

INTRODUCTION: Sleep plays a critical role in daily functioning and stroke recovery but receives little attention in stroke rehabilitation. Sleep disturbances are linked to affective and cognitive impairments, but temporal associations between sleep and affect and cognitive symptoms are less clear. Understanding these temporal associations may inform new directions in intervention and prevention to support continued stroke recovery. OBJECTIVE: To examine the bidirectional temporal associations between sleep and affect and cognitive symptoms among community-dwelling stroke survivors. DESIGN: A secondary analysis of a longitudinal observational study involving 7 days of ecological momentary assessment (EMA), during which participants completed eight EMA surveys and a sleep diary per day. Multilevel modeling was used to analyze data. SETTING: Community. PARTICIPANTS: Community-dwelling stroke survivors (N = 40). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: EMA measures of depressed affect, cheerful affect, and cognitive symptoms. Sleep quality and duration as measured using a sleep diary. RESULTS: Between-person sleep quality was negatively associated with next-day depressed affect (B = -.16; p = .028) and positively associated with next-day cheerful affect (B = .63; p < .001). Inversely, between-person depressed affect was negatively associated with next night sleep quality (B = -.77; p = .015), and vice versa for cheerful affect (between-person: B = .45; p < .001; within-person: B = .09; p = .008). Long sleep (>9 hours) was positively associated with next-day cognitive symptoms (B = .13; p = .002), whereas cognitive symptoms were associated with a higher odds of long sleep the following night (odds ratio [OR] = 0.25; p = .047). CONCLUSIONS: This study identified the bidirectional associations of sleep with affect and cognitive symptoms in the context of the everyday life of stroke survivors. The findings suggest that interventions addressing sleep quality and duration may impact affect and cognitive symptoms, and vice versa.

ABSTRACT

IMPORTANCE: Guidance is limited for training protocols that support stakeholders who are new to participating in telerehabilitation interventions using videoconferencing software. OBJECTIVE: To explore stakeholders' experiences participating in a group-based intervention during the coronavirus disease 2019 (COVID-19) pandemic using a videoconferencing software (Zoom). DESIGN: Ad hoc exploratory thematic analysis. SETTING: Community-based telerehabilitation. PARTICIPANTS: Stakeholders included group members (n = 8) who were low-income adults with chronic stroke (≥3 mo) and mild to moderate disability (National Institutes of Health Stroke Scale ≤ 16), group leaders (n = 4), and study staff (n = 4). INTERVENTION: Group-based intervention, ENGAGE, delivered using videoconferencing technology. ENGAGE blends social learning and guided discovery to facilitate community and social participation. OUTCOMES AND MEASURES: Semistructured interviews. RESULTS: Stakeholders included group members (ages 26-81 yr), group leaders (ages 32-71 yr), and study staff (ages 23-55 yr). Group members characterized ENGAGE as learning, doing, and connecting with others who shared their experience. Stakeholders identified social advantages and disadvantages to the videoconferencing environment. Attitudes toward technology, past technology experiences, the amount of time allotted for training, group size, physical environments, navigation of technology disruptions, and design of the intervention workbook were facilitators for some and barriers for others. Social support facilitated technology access and intervention engagement. Stakeholders recommended training structure and content. CONCLUSIONS AND RELEVANCE: Tailored training protocols may support stakeholders who are participating in telerehabilitation interventions using new software or devices. Future studies that identify specific tailoring variables will advance the development of telerehabilitation training protocols. What This Article Adds: These findings provide stakeholder-identified barriers and facilitators, in addition to stakeholder-informed recommendations, for technology training protocols that may support uptake of telerehabilitation in occupational therapy.

ABSTRACT

Strategy training is a multidisciplinary rehabilitation approach that teaches skills to reduce disability among those with cognitive impairments following a stroke. Strategy training has been shown in randomized, controlled clinical trials to be a more feasible and efficacious intervention for promoting independence than traditional rehabilitation approaches. A standardized fidelity assessment is used to measure adherence to treatment principles by examining guided and directed verbal cues in video recordings of rehabilitation sessions. Although the fidelity assessment for detecting guided and directed verbal cues is valid and feasible for single-site studies, it can become labor intensive, time consuming, and expensive in large, multi-site pragmatic trials. To address this challenge to widespread strategy training implementation, we leveraged natural language processing (NLP) techniques to automate the strategy training fidelity assessment, i.e., to automatically identify guided and directed verbal cues from video recordings of rehabilitation sessions. We developed a rule-based NLP algorithm, a long-short term memory (LSTM) model, and a bidirectional encoder representation from transformers (BERT) model for this task. The best performance was achieved by the BERT model with a 0.8075 F1-score. This BERT model was verified on an external validation dataset collected from a separate major regional health system and achieved an F1 score of 0.8259, which shows that the BERT model generalizes well. The findings from this study hold widespread promise in psychology and rehabilitation intervention research and practice.

ABSTRACT

Quality of life (QOL) and life satisfaction are important research priorities for autistic adults. As such, we saw a need to evaluate individual items of commonly used subjective QOL scales to understand how they are interpreted and perceived by autistic adults. This study used cognitive interviews and repeated sampling to evaluate the accessibility, test-retest reliability and internal consistency of several common QOL measures in a sample of young autistic adults (n = 20; aged 19-32). Cognitive interviews suggested that the Satisfaction with Life Scale was well understood and demonstrated excellent internal consistency and test-retest reliability. While the WHOQoL-BREF and WHOQoL Disability Modules had adequate reliability, cognitive interviews suggested that additional instructions and examples would further enhance their accessibility for use with autistic adults.

ABSTRACT

BACKGROUND: Strategy training is an intervention that may reduce disability when delivered in inpatient rehabilitation following stroke. However, shorter lengths of stay and challenges with continuity of care following discharge results in difficulties in achieving adequate intervention dosage and carryover of training. OBJECTIVE: We examined whether strategy training using a mobile health platform (iADAPT) is feasible during inpatient stroke rehabilitation and following discharge. METHODS: In this RCT, participants were randomized to receive strategy training using either the iADAPT application (n = 16) or a workbook (n = 15). Participants in both groups received 7 in-person sessions during inpatient rehabilitation and 3 remote sessions following discharge. We calculated descriptive statistics to examine acceptance, attendance, and adherence, and within-group effect sizes on satisfaction and disability. RESULTS: Participants in the iADAPT group attended fewer total intervention sessions (n = 5.5, workbook n = 9.0) but attempted a similar number of goals (n = 7.6, workbook n = 8.2). Both groups reported similar satisfaction with in-person intervention (Treatment Expectancy: iADAPT d = 0.60, workbook d = 0.47; Patient Provider Connection: iADAPT d = 0.18, workbook d = 0.31), but the mobile health group reported greater satisfaction with remote intervention (Treatment Expectancy: iADAPT d = -0.91, workbook d = -0.97; Patient Provider Connection: iADAPT d = 0.85, workbook d = -1.80). . CONCLUSIONS: Considering these promising feasibility metrics and the benefits of mobile health, it is worth continuing to explore the efficacy of strategy training using a mobile health platform.

ABSTRACT

BACKGROUND: Community participation is an important outcome of rehabilitation following traumatic brain injury. Yet, few measures assess inclusion and belonging (enfranchisement) as a dimension of community participation. The Enfranchisement scale of the Community Participation Indicators addresses this need. However, research on its psychometric properties is lacking. OBJECTIVE: To examine cut points and sensitivity to change of the Enfranchisement scale of the Community Participation Indicators in adults with traumatic brain injury. DESIGN: This was a repeated measures study with assessments administered twice (3 months apart). SETTING: Assessments were administered either over the phone, virtually (Zoom), or in person at the participant's home. PARTICIPANTS: A total of 44 participants from community settings who had either experienced a traumatic brain injury within the previous year or were receiving rehabilitation interventions were recruited. MAIN OUTCOME MEASURE: The Enfranchisement scale has two subscales: the Control subscale (range: 13-65) and the Importance subscale (range: 14-70). On both subscales, lower scores indicate better enfranchisement. METHODS: The software SAS PROC Logistic and the macro %ROCPlot were used to examine cut points at varying levels of sensitivity and specificity. The area under the receiver operating characteristics curve was calculated to determine overall classification accuracy. Minimum detectable change and minimal clinically important difference were also calculated. RESULTS: For the Control subscale, a cut point of 44 (area under the curve = .75), a minimum detectable change of 8, and a minimal clinically important difference of 5 were found. For the Importance subscale, a cut point of 39 (area under the curve = .81), a minimum detectable change of 8, and a minimal clinically important difference of 5 were found. CONCLUSIONS: The cut points resulted in good classification accuracy, providing support for their reliability. The results provided evidence that both subscales are sensitive to change in adults with brain injury.

ABSTRACT

OBJECTIVE: Stroke symptoms fluctuate during the day as stroke survivors participate in daily activities. Understanding the real-time associations among stroke symptoms and depressed mood, as well as the role of motivation for daily activities, informs, and post-stroke symptom management in the context of everyday living. This study aimed to (1) investigate the real-time associations of fatigue, cognitive complaints, and pain with depressed mood and (2) examine the role of motivation for daily activity participation as a potential moderator of these associations in stroke survivors. DESIGN: A prospective cohort study involving 7 days of ecological momentary assessment (EMA), during which participants completed 8 EMA surveys per day. Multilevel modeling was used to analyze data. SETTING: Community. PARTICIPANTS: Forty community-dwelling stroke survivors (N=40). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: EMA measures of depressed mood, stroke symptoms (physical and mental fatigue, cognitive complaints, and pain), and motivation (autonomous motivation, controlled motivation). RESULTS: Higher levels of within- and between-person physical fatigue, mental fatigue, cognitive complaints, and pain were momentarily associated with greater depressed mood (Ps<.001). Within-person autonomous motivation significantly buffered the momentary associations of physical fatigue (B=-0.06, P<.001), mental fatigue (B=-0.04, P=.032), and pain (B=-0.21, P<.001) with depressed mood. CONCLUSIONS: Findings indicate the momentary associations of fatigue, cognitive complaints, and pain with depressed mood in stroke survivors. Autonomous motivation underpinning daily activity participation was found to buffer the associations of fatigue and pain with depressed mood. Promoting autonomous motivation for daily activity participation may be viable for preventing and mitigating poststroke depression.

ABSTRACT

OBJECTIVES: Routine implementation of cognitive screening and assessment by therapy providers in post-acute settings may promote improved care coordination. This study examined the frequency of cognitive screening and assessment documentation across post-acute settings, as well as its relationship with contextual factors and outcomes. DESIGN: Cross-sectional observational study using Medicare claims and electronic health record data from 1 large health system. SETTING AND PARTICIPANTS: Older adults admitted to post-acute care after an acute hospitalization. METHODS: Descriptive analysis examined documentation of cognitive screening and assessment. Logistic and hierarchical linear regression evaluated the relationship among patient factors, cognitive screening and assessment, and patient outcomes. RESULTS: The most common admission diagnoses for the final sample (n=2535) were total hip or knee joint replacement (41.7%) and stroke (15.3%). Following acute hospitalization, patients were discharged to inpatient rehabilitation (22.6%), skilled nursing (9.3%), or home health (68.1%). During the post-acute care stay, 38% of patients had documentation of cognitive screening by any therapy discipline. Patterns of documentation varied across disciplines and post-acute settings. Documentation of standardized cognitive assessments was limited, occurring for less than 2% of patients. Admission for stroke was associated with significantly higher odds of cognitive screening or assessment [odds ratio (OR) 2.07, 95% CI 1.13, 3.82] compared to patients with other diagnoses. There was no significant relationship between documentation of cognitive screening or assessment and 30-day readmissions (OR 0.81, 95% CI 0.53, 1.28). CONCLUSION AND IMPLICATIONS: The key finding was inconsistent documentation of cognitive screening and assessment across disciplines and post-acute settings, which could be in part due to variation in electronic health record platforms. Future work can expand on these results to understand the degree to which contextual factors facilitate or inhibit routine delivery and documentation of cognitive screening and assessment. Findings can support implementation of standardized data elements to lead to improved care coordination and outcomes.

ABSTRACT

OBJECTIVE: The purpose of this exploratory study was to describe associations between NIH Toolbox-Cognition Battery subtests and legacy measures of neurocognitive function in two samples with neurological conditions (stroke and sickle cell disease (SCD)). METHOD: This exploratory secondary analysis uses data from two studies that assessed cognition at one time point using the NIH Toolbox-Cognition Battery, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), and subtests from the Delis-Kaplan Executive Functions System (DKEFS). People with stroke (n = 26) and SCD (n = 64) were included. Associations between the NIH Toolbox-Cognition Battery subtests and corresponding legacy measures were examined using linear correlations, Bland-Altman analysis, and Lin's Concordance Correlation Coefficient. RESULTS: Linear correlations and Lin's Concordance Correlation Coefficient were poor to strong in both samples on NIH Toolbox-CB subtests: Flanker Inhibitory Control and Attention (r = .35 to .48, Lin CCC = .27 to .37), Pattern Comparison Processing Speed (r = .40 to .65, Lin CCC = .37 to .62), Picture Sequence Memory (r = .19 to .55, Lin CCC = .18 to .48), Dimensional Change Card Sort (r = .39 to .77, Lin CCC = .38 to .63), Fluid Cognition Composite (r = .88 to .90, Lin CCC = .60 to .79), and Total Cognition Composite (r = .64 to .83, Lin CCC = .60 to .78). Bland-Altman analyses demonstrated wide limits of agreement across all subtests (-3.17 to 3.78). CONCLUSIONS: The NIH Toolbox-Cognition Battery subtests may behave similarly to legacy measures as an overall assessment of cognition across samples at risk for neurological impairment. Findings should be replicated across additional clinical samples.

ABSTRACT

PURPOSE: Strategy training is a promising stroke rehabilitation intervention commonly delivered in Western countries. We examined the perspectives of rehabilitation therapists who have delivered strategy training in Taiwan and the United States to understand the influence of culture on strategy training implementation. MATERIALS AND METHODS: In this rapid ethnographic study, the maximum variation sampling approach was used to recruit seven therapists in Taiwan and seven therapists in the United States with experience delivering strategy training. Data was collected from multiple sources, including interviews, study documents, therapist notes, and reflective memos. Interviews with the recruited therapists in Taiwan and the United States were conducted in Mandarin and English, respectively. Data were analyzed using a constant comparative approach. RESULTS: The following two themes were generated: (1) differences between conventional rehabilitation and strategy training, namely that conventional rehabilitation is therapist-directed and emphasizes impairment reduction, whereas strategy training empowers clients and focuses on real-life generalization, and (2) challenges in implementing strategy training in practice, including difficulty in achieving client buy-in and disengagement. CONCLUSIONS: Therapists from both countries shared similar perspectives on the perceived advantages of strategy training, such as enhancing client empowerment and engagement, and the generalization of strategies. Family involvement was more prominently discussed by therapists in Taiwan than by those in the United States.IMPLICATIONS FOR REHABILITATIONStrategy training differs from conventional rehabilitation in its emphasis on clients' life participation and empowerment, generalization of strategies, and enhancement of their engagement, confidence, and problem-solving skills.Therapists may face challenges related to client buy-in and disengagement as well as difficulties in establishing a therapeutic rapport at the beginning of strategy training because clients have different expectations from those of conventional rehabilitation.Cultural differences in norms and expectations and the clinical experiences of therapists may influence the delivery of strategy training to clients.Family support may influence the success of strategy training.Thoughtful conversations to reach a mutual understanding regarding the expectations of strategy training among clients, family, and rehabilitation practitioners are necessary prior to implementing strategy training.

ABSTRACT

We aim to build a system incorporating electroencephalography (EEG) and augmented reality (AR) that is capable of identifying the presence of visual spatial neglect (SN) and mapping the estimated neglected visual field. An EEG-based brain-computer interface (BCI) was used to identify those spatiospectral features that best detect participants with SN among stroke survivors using their EEG responses to ipsilesional and contralesional visual stimuli. Frontal-central delta and alpha, frontal-parietal theta, Fp1 beta, and left frontal gamma were found to be important features for neglect detection. Additionally, temporal analysis of the responses shows that the proposed model is accurate in detecting potentially neglected targets. These targets were predicted using common spatial patterns as the feature extraction algorithm and regularized discriminant analysis combined with kernel density estimation for classification. With our preliminary results, our system shows promise for reliably detecting the presence of SN and predicting visual target responses in stroke patients with SN.

ABSTRACT

OBJECTIVE: To identify critical illness survivors' perceived barriers and facilitators to resuming performance of meaningful activities when transitioning from hospital to home. DESIGN: Secondary content analysis of semistructured interviews about patients' experiences of intensive care (primary analysis disseminated on the patient-facing website www.healthtalk.org). Two coders characterised patient-perceived barriers and facilitators to resuming meaningful activities. To facilitate clinical application, we mapped the codes onto the Person-Task-Environment model of performance, a patient-centred rehabilitation model that characterises complex interactions among the person, task and environment when performing activities. SETTING: United Kingdom, 2005-2006. PARTICIPANTS: 39 adult critical illness survivors, sampled for variation among demographics and illness experiences. RESULTS: Person-related barriers included negative mood or affect, perceived setbacks; weakness or limited endurance; pain or discomfort; inadequate nutrition or hydration; poor concentration/confusion; disordered sleep/hallucinations/nightmares; mistrust of people or information; and altered appearance. Task-related barriers included miscommunication and managing conflicting priorities. Environment-related barriers included non-supportive health services and policies; challenging social attitudes; incompatible patient-family coping (emotional trauma and physical disability); equipment problems; overstimulation; understimulation; and environmental inaccessibility. Person-related facilitators included motivation or attitude; experiencing progress; and religion or spirituality. Task-related facilitators included communication. Environment-related facilitators included support from family, friends or healthcare providers; supportive health services and policies; equipment; community resources; medications; and accessible housing. Barriers decreased and facilitators increased over time. Six barrier-facilitator domains dominated based on frequency and emphasis across all performance goals: mood/motivation, setbacks/progress, fatiguability/strength; mis/communication; lack/community support; lack/health services and policies. CONCLUSIONS: Critical illness survivors described a comprehensive inventory of 18 barriers and 11 facilitators that align with the Person-Task-Environment model of performance. Six dominant barrier-facilitator domains seem strong targets for impactful interventions. These results verify previous knowledge and offer novel opportunities for optimising patient-centred care and reducing disability after critical illness.

ABSTRACT

Significant advancements in acute stroke medical management have changed stroke rehabilitation. In addition, an ever-changing health care ecosystem and heightened awareness of continued and new challenges requires that the occupational therapy profession consider new, innovative, and pragmatic approaches to measurement, intervention, and health services research, and clinical practice. The profession must elevate the focus and rigor of research examining occupation and participation after stroke, and their associations with health. Intervention research must progress beyond early phase pilot studies to a robust collection of meaningful large multisite studies that demonstrate the effectiveness of our interventions and the effectiveness of wide-scale implementation to ensure quality and consistent delivery of evidence-based practices in occupational therapy. These studies must address the accessibility of these practices for all people who have sustained stroke, and particularly those people who are most vulnerable to inaccessible stroke rehabilitation service delivery systems.

ABSTRACT

OBJECTIVE: To characterize the intervention elements associated with improvements in activity and participation outcomes for adults with brain injury. DATA SOURCES: PubMed and PsycINFO/Ovid. STUDY SELECTION: We included RCTs that examined interventions for adults with acquired brain injury with an activity or participation outcome measure. DATA EXTRACTION: We classified intervention elements and extracted effect sizes. We examined patterns of effect sizes associated with each intervention element based on time of follow-up and level of outcome (home versus community). DATA SYNTHESIS: Thirty-nine articles were included. Outcomes focused on the performance of home and community activities. There was wide variation in effect sizes across all intervention elements, as well as by time and by outcome level (home versus community). Metacognitive interventions and daily life skills interventions showed the greatest promise for improving performance of home and community activities. Additionally, cognitive training interventions may play a role in improving home activity performance and social skills training interventions may play a role in community activity performance. Physical activity interventions showed the least promise for improving home and community activity performance. CONCLUSION: This study highlights the importance of interventions that incorporate explicit strategies and task-specific training, rather than only addressing specific injury-related impairments.

ABSTRACT

BACKGROUND: Strategy training, a rehabilitation intervention, reduces disability and improves functional skills associated with goal-directed behavior. Stroke lesions impacting selected ventromedial regions of interest associated with initiation of goal-directed behavior may attenuate intervention response. If so, strategy training may not be optimal for people with stroke lesions in these regions. OBJECTIVE: To examine whether ventromedial regions of interest attenuate changes in disability status attributed to strategy training. DESIGN: Secondary analysis of data from two randomized controlled clinical trials. SETTING: Inpatient stroke rehabilitation. PARTICIPANTS: People with acute stroke diagnosis and available diagnostic studies enrolled in inpatient rehabilitation randomized controlled studies between 2009 and 2017. INTERVENTION: Participants were randomized to strategy training or a control condition in addition to the usual care during inpatient rehabilitation. MAIN OUTCOME MEASURES: Diagnostic magnetic resonance imaging studies were retrieved from electronic medical records, and stroke lesion location was characterized by a neuroradiologist. Intervention response was defined by Functional Independence Measure change scores of 22 points or greater. RESULTS: Only 186 of 275 participants had diagnostic studies available; 13 patients showed no apparent lesion on their diagnostic study. Among 173 cases, 156 had complete data at discharge (strategy training n = 71, control n = 85). Twenty-five cases had a lesion within a region of interest (strategy training n = 14, control n = 11). Intervention response was attenuated in the strategy training group for those with lesions in regions of interest [χ2 (1, n = 71) = 4.60, P = .03], but not for those in the control group [Fisher exact test, n = 85, P = .19). CONCLUSIONS: Lesions in the ventromedial regions of interest may attenuate response to strategy training.
