The Impact of Mild Stroke on Meaningful Activity and Life Satisfaction

ENGAGE-TBI: adaptation of a community-based intervention to improve social participation after brain injury

BACKGROUND

Social isolation is prevalent after traumatic brain injury (TBI) and has negative implications for health and well-being. Interventions targeting social participation show promise for reducing social isolation. We adapted a social participation intervention, ENGAGE, to meet the needs of people with TBI. ENGAGE relies on social learning and guided problem-solving to achieve social participation goals.

METHODS

This study was conducted in two phases. First, we conducted focus groups with 12 participants with TBI to inform adaptations. We then tested the adapted protocol (n = 6). Post-intervention interviews informed additional refinements. We collected preliminary data on feasibility and effects on social participation (Activity Card Sort, PROMIS Ability to Participate in Social Roles, PROMIS Satisfaction with Participation in Social Roles) and social isolation (PROMIS Social Isolation).

RESULTS

Intervention adaptations included simplified processes for developing goals and plans, simplified workbook materials, greater time for reflection on lessons learned, and expanded peer mentorship. ENGAGE-TBI resulted in high satisfaction for 80% of participants and high engagement in intervention for 100% of participants. Attendance and retention benchmarks were achieved. Improvements in social participation exceeded the minimal clinically important difference on all measures.

CONCLUSIONS

The promising preliminary data support further investigation into the feasibility and effects of ENGAGE-TBI.

Early neuropsychological screening and long-term functional outcome in a sample of patients affected by mild stroke: The ReSCog Project

Stroke causes severe long-term disabilities with a significant reduction in quality of life. This study aims to explore the predictive value of cognitive screening in the acute phase of mild stroke on patients' functional outcome after discharge. A total of 110 patients with mild stroke were recruited. Patients were included in the study if they were discharged directly home from the acute units. The cognitive profile of patients was assessed with the Oxford Cognitive Screen (OCS). The OCS was administered 3-10 days after stroke, providing a five domain-specific cognitive profile. Long-term functional outcomes were evaluated by the Stroke Impact Scale 3.0 (SIS 3.0), a self-reported questionnaire that includes physical, cognitive, emotional and social participation dimensions. All patients completed the survey online on average 10 months after stroke. Our results show that OCS is positively associated with physical and cognitive dimensions, after adjusting for age and stroke severity measured by NIHSS at admission. In conclusion, OCS in acute mild stroke seems to be an independent predictor of long-term functional outcomes and could help clinicians in the long-term management of patients.

An ANN models cortical-subcortical interaction during post-stroke recovery of finger dexterity

Objective.Finger dexterity, and finger individuation in particular, is crucial for human movement, and disruptions due to brain injury can significantly impact quality of life. Understanding the neurological mechanisms responsible for recovery is vital for effective neurorehabilitation. This study explores the role of two key pathways in finger individuation: the corticospinal (CS) tract from the primary motor cortex and premotor areas, and the subcortical reticulospinal (RS) tract from the brainstem. We aimed to investigate how the cortical-reticular network reorganizes to aid recovery of finger dexterity following lesions in these areas.Approach.To provide a potential biologically plausible answer to this question, we developed an artificial neural network (ANN) to model the interaction between a premotor planning layer, a cortical layer with excitatory and inhibitory CS outputs, and RS outputs controlling finger movements. The ANN was trained to simulate normal finger individuation and strength. A simulated stroke was then applied to the CS area, RS area, or both, and the recovery of finger dexterity was analyzed.Main results.In the intact model, the ANN demonstrated a near-linear relationship between the forces of instructed and uninstructed fingers, resembling human individuation patterns. Post-stroke simulations revealed that lesions in both CS and RS regions led to increased unintended force in uninstructed fingers, immediate weakening of instructed fingers, improved control during early recovery, and increased neural plasticity. Lesions in the CS region alone significantly impaired individuation, while RS lesions affected strength and to a lesser extent, individuation. The model also predicted the impact of stroke severity on finger individuation, highlighting the combined effects of CS and RS lesions.Significance.This model provides insights into the interactive role of cortical and subcortical regions in finger individuation. It suggests that recovery mechanisms involve reorganization of these networks, which may inform neurorehabilitation strategies.

"Going under the radar": barriers to continuity in the rehabilitation trajectories of adults with acquired brain injury in North Norway

PURPOSE

Acquired Brain Injury (ABI) is a major cause of disability, but rehabilitation services for adults with ABI discharged home remains deficient. This study explores barriers to continuity in the rehabilitation trajectories of this population in North Norway.

MATERIALS AND METHODS

Data were generated from focus groups consisting of individuals with ABI and family caregivers (n = 5) and healthcare professionals (n = 14). Purposeful sampling of participants (total n = 19) ensured diverse perspectives. A reflexive thematic analytical approach was applied to identify recurring themes.

RESULTS

This study reveals significant misalignment between the support needs of home-dwelling adults with ABI and the existing healthcare system in North Norway. Four themes were identified: (1) A lack of awareness of patient rehabilitation needs in hospitals, (2) individuals with ABI slipping through the cracks during transitions, (3) constraints in municipal healthcare services' capacity, and (4) unclear rehabilitation pathways for individuals with ABI.

CONCLUSIONS

Individuals with ABI need assistance navigating complex healthcare systems, gaining insight into their functional problems, and expressing needs and goals. The findings support calls for a paradigm shift in ABI rehabilitation, advocating for a transition from impairment-focused to reengagement-oriented practices as individuals with ABI transition from inpatient to home settings with increasingly stable residual impairments.

Physiotherapists' and occupational therapists' experiences with cross-sectoral coordination of rehabilitation for people with mild stroke - a qualitative interview study

PURPOSE

To meet the needs of people with mild stroke, multidisciplinary, person-centred, cross-sectoral rehabilitation is internationally recommended. However, there seem to be gaps in the rehabilitation process. The aim of this study was to investigate how occupational therapists and physiotherapists experience working in cross-sectoral rehabilitation for people with mild stroke.

MATERIALS AND METHODS

Data were generated through interviews with occupational therapists and physiotherapists working in four different Danish rehabilitation settings. Four group interviews and two individual interviews with a total of 19 participants were conducted. Ricoeur's theory of interpretation was used to interpret and discuss the data.

RESULTS

Four themes were identified: the risk of overlooking symptoms: better safe than sorry; varying degrees of involvement of people with mild stroke; spontaneous involvement of relatives; and contextual challenges for coherence in the rehabilitation process.

CONCLUSION

The therapists experienced challenges in coordinating rehabilitation across sectors due to the timing of the needs assessment and contextual challenges. They used a preventive strategy of sending a plan or referral for later re-assessment. The therapists involved people with mild stroke to varying degrees. They involved relatives spontaneously. For successful rehabilitation, ongoing assessment, recognition of collaboration factors and relative involvement are essential.

Is Mild Really Mild?: Generating Longitudinal Profiles of Stroke Survivor Impairment and Impact Using Unsupervised Machine Learning

The National Institute of Health Stroke Scale (NIHSS) is used worldwide to classify stroke severity as ‘mild’, ‘moderate’, or ‘severe’ based on neurological impairment. Yet, stroke survivors argue that the classification of ‘mild’ does not represent the holistic experience and impact of stroke on their daily lives. In this observational cohort study, we aimed to identify different types of impairment profiles among stroke survivors classified as ‘mild’. We used survivors of mild stroke’ data from the START longitudinal stroke cohort (n = 73), with measures related to sensorimotor, cognition, depression, functional disability, physical activity, work, and social adjustment over 12 months. Given the multisource, multigranular, and unlabeled nature of the data, we utilized a structure-adapting, unsupervised machine learning approach, the growing self-organizing map (GSOM) algorithm, to generate distinct clinical profiles. These diverse impairment profiles revealed that survivors of mild stroke experience varying degrees of impairment and impact (cognitive, depression, physical activity, work/social adjustment) at different time points, despite the uniformity implied by their NIHSS-classified ‘mild’ stroke. This emphasizes the necessity of creating a holistic and more comprehensive representation of survivors of mild stroke’ needs over the first year after stroke to improve rehabilitation and poststroke care.

Regional Disparities in Prehospital Delay of Acute Ischemic Stroke: The Korean Stroke Registry

BACKGROUND

Late hospital arrival keeps patients with stroke from receiving recanalization therapy and is associated with poor outcomes. This study used a nationwide acute stroke registry to investigate the trends and regional disparities in prehospital delay and analyze the significant factors associated with late arrivals.

METHODS

Patients with acute ischemic stroke or transient ischemic attack between January 2012 and December 2021 were included. The prehospital delay was identified, and its regional disparity was evaluated using the Gini coefficient for nine administrative regions. Multivariate models were used to identify factors significantly associated with prehospital delays of >4.5 h.

RESULTS

A total of 144,014 patients from 61 hospitals were included. The median prehospital delay was 460 min (interquartile range, 116-1912), and only 36.8% of patients arrived at hospitals within 4.5 h. Long prehospital delays and high regional inequality (Gini coefficient > 0.3) persisted throughout the observation period. After adjusting for confounders, age > 65 years old (adjusted odds ratio [aOR] = 1.23; 95% confidence interval [CI], 1.19-1.27), female sex (aOR = 1.09; 95% CI, 1.05-1.13), hypertension (aOR = 1.12; 95% CI, 1.08-1.16), diabetes mellitus (aOR = 1.38; 95% CI, 1.33-1.43), smoking (aOR = 1.15, 95% CI, 1.11-1.20), premorbid disability (aOR = 1.44; 95% CI, 1.37-1.52), and mild stroke severity (aOR = 1.55; 95% CI, 1.50-1.61) were found to independently predict prehospital delays of >4.5 h.

CONCLUSION

Prehospital delays were lengthy and had not improved in Korea, and there was a high regional disparity. To overcome these inequalities, a deeper understanding of regional characteristics and further research is warranted to address the vulnerabilities identified.

Prevalence, patterns, and predictors of patient-reported non-motor outcomes at 30 days after acute stroke: Prospective observational hospital cohort study

BACKGROUND

Adverse non-motor outcomes are common after acute stroke and likely to substantially affect quality of life, yet few studies have comprehensively assessed their prevalence, patterns, and predictors across multiple health domains.

AIMS

We aimed to identify the prevalence, patterns, and the factors associated with non-motor outcomes 30 days after stroke.

METHODS

This prospective observational hospital cohort study-Stroke Investigation in North and Central London (SIGNAL)-identified patients with acute ischemic stroke or intracerebral hemorrhage (ICH) admitted to the Hyperacute Stroke Unit (HASU) at University College Hospital (UCH), London, between August 1, 2018 and August 31, 2019. We assessed non-motor outcomes (anxiety, depression, fatigue, sleep, participation in social roles and activities, pain, bowel function, and bladder function) at 30-day follow-up using the Patient-Reported Outcome Measurement Information System-Version 29 (PROMIS-29) scale and Barthel Index scale.

RESULTS

We obtained follow-up data for 605/719 (84.1%) eligible patients (mean age 72.0 years; 48.3% female; 521 with ischemic stroke, 84 with ICH). Anxiety (57.0%), fatigue (52.7%), bladder dysfunction (50.2%), reduced social participation (49.2%), and pain (47.9%) were the commonest adverse non-motor outcomes. The rates of adverse non-motor outcomes in ⩾ 1, ⩾ 2 and ⩾ 3 domains were 89%, 66.3%, and 45.8%, respectively; in adjusted analyses, stroke due to ICH (compared to ischemic stroke) and admission stroke severity were the strongest and most consistent predictors. There were significant correlations between bowel dysfunction and bladder dysfunction (κ = 0.908); reduced social participation and bladder dysfunction (κ = 0.844); and anxiety and fatigue (κ = 0.613). We did not identify correlations for other pairs of non-motor domains.

CONCLUSION

Adverse non-motor outcomes were very common at 30 days after stroke, affecting nearly 90% of evaluated patients in at least one health domain, about two-thirds in two or more domains, and almost 50% in three or more domains. Stroke due to ICH and admission stroke severity were the strongest and most consistent predictors. Adverse outcomes occurred in pairs of domains, such as with anxiety and fatigue. Our findings emphasize the importance of a multi-domain approach to effectively identify adverse non-motor outcomes after stroke to inform the development of more holistic patient care pathways after stroke.

Occupational Therapy Practice: Time From Stroke Onset to Outpatient Upper Limb Rehabilitation

Upper limb stroke rehabilitation has been understudied in usual occupational therapy. The study's purpose was to describe the timing and amount of usual occupational therapy in the stroke population for hospital-based outpatient upper limb rehabilitation. A multi-site study of timing and amount of occupational therapy was calculated for mild and moderate upper limb stroke impairments using the Fugl-Meyer Assessment-Upper Extremity (FMA-UE). Mild stroke participants (n = 58) had a mean of 164.25 days, and the moderate stroke participants (n = 64) had a mean of 106.75 days from the date of stroke onset to first treatment which was significantly different (p = .047). There were no significant differences in the amount of therapy between mild or moderate stroke patients. Mild stroke patients experience a longer delay in receiving outpatient occupational therapy compared with moderate impairments which may be attributed to the subtlety of the impairments that impact participation in daily activities.

Quality of Life in Patients with Excellent 3-Month Clinical Outcome after First-Ever Ischemic Stroke: A Time to Redefine Excellent Outcome?

INTRODUCTION

Ischemic stroke (IS) may have impact on long-term health-related quality of life (HRQoL) even in the patients with good clinical outcome, and tools mostly used for the assessment of outcome may underestimate or not reflect all relevant sequels after IS. We aimed to analyze HRQoL in the patients with excellent outcome after IS.

METHODS

We analyzed consecutive IS patients enrolled in the prospective FRAILTY study (ClinicalTrials.gov: NCT04839887) with excellent 3-month clinical outcome (score 0-1 in modified Rankin Scale [mRS]). Stroke Impact Scale (SIS) version 3.0 and Hospital Anxiety and Depression Scale (HADS) were used for the HRQoL, anxiety, and depression assessments, and subgroup comparisons were performed according to NIHSS score (0, ≥1), age (50<, ≥50 years), and sex.

RESULTS

In total, 158 patients (55.7% men, mean age 60.3 ± 13.4 years) were analyzed, and 72.2% of them had score 0 in mRS. The overall lowest median scores were found in the SIS domain "emotion," "strength," and "participation." Patients with NIHSS ≥1 had lower scores in all SIS domains except "emotions" and "mobility." Patients ≥50 years had lower score in "mobility" (p = 0.004) and females in domain of "social participation" (p = 0.044). No differences were found among all subgroups in HADS anxiety and depression. Age, NIHSS score, and depression were found negative predictors for the physical domains of HRQoL.

DISCUSSION/CONCLUSIONS

Despite excellent 3-month clinical outcome after IS, patients had affected substantially their HRQoL, especially those with NIHSS ≥1. Patients ≥50 years had more affected "mobility" and females "social participation."

Participation and Its Association With Health Among Community-Dwelling Adults With Chronic Stroke

IMPORTANCE

Little is known about the severity of participation restrictions among people living in the community with chronic stroke. Even less is known about the association between participation and health in this population.

OBJECTIVE

To describe participation among people with chronic stroke and examine the association between participation and physical and mental health.

DESIGN

Secondary analysis of baseline data from an intervention study.

SETTING

The parent multisite intervention study was conducted in the community, and assessments were administered in participants' homes.

PARTICIPANTS

Thirty-one community-dwelling adults with chronic stroke.

OUTCOMES AND MEASURES

Participation was measured with the Activity Card Sort (percentage of prestroke activities retained) and the Enfranchisement Scale of the Community Participation Indicators. Health was measured with the PROMIS®-29 Physical Health and Mental Health subscales. We calculated descriptive statistics for participation measures and Spearman's ρ correlations between participation and health outcomes.

RESULTS

Participation scores were poor on all measures of participation. Most striking, 94.9% of participants retained less than 80% of their prestroke activities. All measures of participation were modestly correlated with physical health (ρ = .28-.46) and were moderately correlated with mental health (ρ = .42-.63).

CONCLUSIONS AND RELEVANCE

Participation restrictions are prevalent among adults with chronic stroke, with potential implications for mental health. Stronger community-based rehabilitation and support services to enhance participation of this high-risk population are warranted. What This Article Adds: This report highlights the severity of participation restrictions among people with chronic stroke. Moreover, this report shows that people with stroke feel a lack of inclusion in the community and that participation is associated with mental and physical health.

Effect of very early supported discharge versus usual care on activi-ties of daily living ability after mild stroke: a randomized controlled trial

OBJECTIVE

To examine the ability to perform basic and instrumental activities of daily life after very early supported discharge vs usual discharge and referral routine during the first year after mild stroke.

DESIGN

A secondary analysis of data from the Gothenburg Very Early Supported Discharge randomized controlled trial.  Patients: A total of 104 patients (56% men; mean (standard deviation) age 75 (11) years) who had experienced a first stroke classified as mild.

METHODS

The primary outcome was the Activities of Daily Living Taxonomy score. Stroke Impact Scale (activities of daily living, and mobility) scores was a secondary measure. Patients were randomized to either very early supported discharge with 4 weeks of home rehabilitation provided by a multidisciplinary stroke team, or a control group discharged according to usual routine (referral to primary care when needed). Assessments were performed at discharge, 4 weeks post-discharge, and 3 and 12 months post-stroke.

RESULTS

Instrumental activities of the Activities of Daily Living Taxonomy scores (the lower the better) in the very early supported discharge and control groups were median 4 and 6 (p = 0.039) at 4 weeks post-discharge and 3 and 4.5 (p = 0.013 at 3 months post-stroke, respectively. Stroke Impact Scale (Mobility) median scores (the higher the better) in the very early supported discharge and control groups at 3 months were 97 and 86 (p = 0.040), respectively. There were no group differences in the 2 outcomes at 12 months post-stroke.

CONCLUSION

Compared with usual discharge routine, team-based rehabilitation during the first month at home is beneficial for instrumental activity in the subacute phase, in patients with mild stroke. One year post-stroke both groups show equal results.

Task Cortical Connectivity Reveals Different Network Reorganizations between Mild Stroke Patients with Cortical and Subcortical Lesions

Accumulating efforts have been made to investigate cognitive impairment in stroke patients, but little has been focused on mild stroke. Research on the impact of mild stroke and different lesion locations on cognitive impairment is still limited. To investigate the underlying mechanisms of cognitive dysfunction in mild stroke at different lesion locations, electroencephalograms (EEGs) were recorded in three groups (40 patients with cortical stroke (CS), 40 patients with subcortical stroke (SS), and 40 healthy controls (HC)) during a visual oddball task. Power envelope connectivity (PEC) was constructed based on EEG source signals, followed by graph theory analysis to quantitatively assess functional brain network properties. A classification framework was further applied to explore the feasibility of PEC in the identification of mild stroke. The results showed worse behavioral performance in the patient groups, and PECs with significant differences among three groups showed complex distribution patterns in frequency bands and the cortex. In the delta band, the global efficiency was significantly higher in HC than in CS (p = 0.011), while local efficiency was significantly increased in SS than in CS (p = 0.038). In the beta band, the small-worldness was significantly increased in HC compared to CS (p = 0.004). Moreover, the satisfactory classification results (76.25% in HC vs. CS, and 80.00% in HC vs. SS) validate the potential of PECs as a biomarker in the detection of mild stroke. Our findings offer some new quantitative insights into the complex mechanisms of cognitive impairment in mild stroke at different lesion locations, which may facilitate post-stroke cognitive rehabilitation.

Factors Affecting the Quality of Sleep and Social Participation of Stroke Patients

(1) Background: Stroke patients are exposed to various psychosocial factors, such as depression, anxiety, and stress, which can cause problems with respect to their quality of sleep and social participation. (2) Objectives: We analyzed the causal relationships between the factors affecting sleep quality and social participation in hospitalized and community-based stroke patients using a path analysis model. (3) Methods: A questionnaire survey was administered to stroke patients from June to November 2020 using the Pittsburgh Sleep Quality Index to assess sleep quality; the Beck Depression Inventory to assess depression; the Beck Anxiety Inventory to assess anxiety; the Stress Scale to assess stress; and the Reintegration to Normal Living Index to assess participation. The data thus obtained were subjected to descriptive statistics, frequency analysis, and Pearson correlation analysis. In addition, anxiety, stress, and spasticity were set as exogenous variables to perform path analysis of their causal effects on depression (parameter), sleep quality, and social participation (final endogenous variables). (4) Results: In total, 145 people participated in this study, and the data of 129 people, excluding 16 insincere respondents, were analyzed. The general characteristics of the subjects comprised 84 males (65.1%) and 45 females (34.9%). Poor sleep quality comprised 54.3%, and good sleep quality comprised 45.7%, where the average age was 58.29 ± 15.46 years and the duration from onset was 39.73 ± 51.49 months. This study confirmed correlations between social participation and sleep quality, spasticity, depression, anxiety, and stress. Path analysis also revealed that anxiety and stress led to depression and that depression is a risk factor for sleep quality and social participation. (5) Conclusions: Sleep quality and social participation in stroke patients play an important role in rehabilitation. By carrying out this study, direct and indirect factors that affect sleep quality and social participation were analyzed, and the quality level in rehabilitation treatment should be improved from a structural point of view when approaching psychosocial factors.

Brain network analysis reveals convergent and divergent aberrations between mild stroke patients with cortical and subcortical infarcts during cognitive task performing

Although consistent evidence has revealed that cognitive impairment is a common sequela in patients with mild stroke, few studies have focused on it, nor the impact of lesion location on cognitive function. Evidence on the neural mechanisms underlying the effects of mild stroke and lesion location on cognitive function is limited. This prompted us to conduct a comprehensive and quantitative study of functional brain network properties in mild stroke patients with different lesion locations. Specifically, an empirical approach was introduced in the present work to explore the impact of mild stroke-induced cognitive alterations on functional brain network reorganization during cognitive tasks (i.e., visual and auditory oddball). Electroencephalogram functional connectivity was estimated from three groups (i.e., 40 patients with cortical infarctions, 48 patients with subcortical infarctions, and 50 healthy controls). Using graph theoretical analysis, we quantitatively investigated the topological reorganization of functional brain networks at both global and nodal levels. Results showed that both patient groups had significantly worse behavioral performance on both tasks, with significantly longer reaction times and reduced response accuracy. Furthermore, decreased global and local efficiency were found in both patient groups, indicating a mild stroke-related disruption in information processing efficiency that is independent of lesion location. Regarding the nodal level, both divergent and convergent node strength distribution patterns were revealed between both patient groups, implying that mild stroke with different lesion locations would lead to complex regional alterations during visual and auditory information processing, while certain robust cognitive processes were independent of lesion location. These findings provide some of the first quantitative insights into the complex neural mechanisms of mild stroke-induced cognitive impairment and extend our understanding of underlying alterations in cognition-related brain networks induced by different lesion locations, which may help to promote post-stroke management and rehabilitation.

Functional and Cognitive Occupational Therapy (FaCoT) Improves Self-Efficacy and Behavioral-Emotional Status of Individuals with Mild Stroke; Analysis of Secondary Outcomes

BACKGROUND

Mild stroke is characterized by subtle impairments, such as low self-efficacy and emotional and behavioral symptoms, which restrict daily living. Functional and Cognitive Occupational Therapy (FaC_oT) is a novel intervention, developed for individuals with mild stroke.

OBJECTIVES

To examine the effectiveness of FaC_oT compared to a control group to improve self-efficacy, behavior, and emotional status (secondary outcome measures).

MATERIAL AND METHODS

Community-dwelling individuals with mild stroke participated in a single-blind randomized controlled trial with assessments at pre, post, and 3-month follow-up. FaC_oT included 10 weekly individual sessions practicing cognitive and behavioral strategies. The control group received standard care. The New General Self-Efficacy Scale assessed self-efficacy; the Geriatric Depression Scale assessed depressive symptoms; the Dysexecutive Questionnaire assessed behavior and emotional status; and the 'perception of self' subscale from the Reintegration to Normal Living Index assessed participation.

RESULTS

Sixty-six participants were randomized to FaC_oT (n = 33, mean (SD) age 64.6 (8.2)) and to the control (n = 33, age 64.4 (10.8)). Self-efficacy, depression, behavior, and emotional status improved significantly over time in the FaC_oT group compared with the control, with small to large effect size values.

CONCLUSION

The efficacy of FaC_oT was established. FaC_oT should be considered for community-dwelling individuals with mild stroke.

Identifying emotional contributors to participation post-stroke

BACKGROUND

Participation in daily activities is the ultimate goal of stroke rehabilitation. Emotional factors have been considered as contributors to participation, but associations between emotional factors and participation post-stroke have not been fully explored.

OBJECTIVE

To investigate the extent to which emotional factors contribute to participation post-stroke.

METHODS

73 participants were included. Three participation outcomes were used as dependent variables in three models: (1) Stroke Impact Scale (SIS) Participation/Role Function, (2) Activity Card Sort (ACS), and (3) Reintegration to Normal Living (RNL). Main independent variables were six emotional factors: SIS Emotion Function (General emotion), Visual Analog Mood Scale energetic and happy subscales, Patient Health Questionnaire-9 (Depression), State-Trait Anxiety Inventory-Trait Anxiety Scale, and Apathy Evaluation Scale. Covariates of stroke severity and social support were included.

RESULTS

Model 1 showed stroke severity (β = -0.300) and depression (β = -0.268) were significant contributors to SIS Participation/Role Function (R² = 0.368, p < .05). Model 2 indicated that happiness (β = 0.284) and apathy (β = -0.330) significantly contributed to ACS total activity retention (R² = 0.247, p < .05). Model 3 revealed that anxiety (β = -0.348), apathy (β = -0.303), stroke severity (β = -0.184), and social support (β = 0.185) were significant contributors to RNL total score (R² = 0.583, p < .05).

CONCLUSIONS

Results suggested that emotional measures of apathy, depression, anxiety, and happiness, but not general emotion, were important contributors to participation post-stroke. These findings suggest that rehabilitation professionals should address individual emotional contributors to facilitate participation post-stroke.

Executive Function Poststroke: Concepts, Recovery, and Interventions

Executive function is frequently impaired among people who have sustained stroke. This review provides an overview of definitions, concepts, and measures. The review also summarizes current best evidence examining executive function impairment and recovery trajectories after stroke, correlates of change over time, and emerging intervention research. Finally, this review provides recommendations for research and clinical practices, as well as priorities for future executive function research.

Subjective and objective assessments are associated for physical function but not cognitive function in community-dwelling stroke survivors

PURPOSE

To investigate the relation between subjectively and objectively assessed cognitive and physical functioning among community-dwelling stroke survivors, and to examine the association of stroke severity with subjectively and objectively assessed cognitive and physical impairments.

MATERIALS AND METHODS

Secondary data analysis was conducted with 127 community-dwelling stroke survivors. For cognitive functioning, objective measures included the NIH Toolbox Cognition Battery and the Executive Function Performance Test; subjective measures included the Quality of Life in Neurological Disorders Applied Cognition. Objective and subjective physical functioning was measured by the NIH Toolbox 2-Minute Walk Test and the Patient-Reported Outcomes Measurement Information System Physical Function, respectively.

RESULTS

A positive correlation was observed between subjective and objective physical functioning, whereas the correlation between subjective and objective cognitive functioning was nonsignificant. Stroke severity was associated with objective cognitive impairment and objective and subjective physical impairment, but not subjective cognitive impairment.

CONCLUSIONS

The lack of association between objective and subjective cognitive functioning challenges the conventional assumption that perceived functioning reflects actual performance. We recommend using both objective and subjective measures to accurately identify cognitive and physical impairment following stroke.Implications for RehabilitationSubjective cognitive functioning is not associated with objective cognitive functioning, suggesting that solely relying on stroke patients' reports is inadequate and may inaccurately estimate patients' actual deficits.Both objective and subjective measures should be used to accurately identify cognitive and physical impairment following stroke.Practitioners should be cognizant of stroke patients' behavioral signs associated with underlying cognitive problems that warrant further evaluation.

Effects of Meaningful Action Observation Therapy on Occupational Performance, Upper Limb Function, and Corticospinal Excitability Poststroke: A Double-Blind Randomized Control Trial

Introduction

Action observation therapy (AOT) is a mirror neuron-based approach that has been recently used in poststroke rehabilitation. The main goal of this study was to investigate the effectiveness of AOT of occupations and tasks that are meaningful for chronic stroke patients on occupational performance, upper-extremity function, and corticospinal changes.

Method

A randomized control trial was designed to compare between experimental (n = 13) and control groups (n = 14). In both groups, the execution of meaningful tasks was practiced, but the videos of those tasks were just shown to the experiment group. Instead, patients in the control group watched nature videos as a placebo. Clinical outcomes were evaluated using the Canadian Occupational Performance Measure (COPM), Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), and Box-Block Test (BBT) on 3 occasions: baseline, post (at 4 weeks), and follow-up (at 8 weeks). The assessments of central motor conduction time (CMCT) for abductor policis brevis (APB) and extensor indicis (EI) were only recorded at baseline and posttreatment. Both assessors of clinical and neurophysiological outcomes were blinded to the allocation of subjects.

Result

Finally, the results of outcomes in 24 patients who completed the study were analyzed. In both groups, significant improvements after treatment were seen for most outcomes (p ≤ 0.05). These changes were persistent until follow-up. There were significant differences in COPM performance (p = 0.03) and satisfaction (p = 0.001) between the experimental and control groups. In contrast, other clinical assessments such as FMA, ARAT, and BBT did not show significant differences between the two treatments (p ≥ 0.05). The results of CMCT related to APB showed a more significant change in the experiment group compared to the control group (p = 0.022). There was no difference in change detected between the two groups for CMCT related to EI after treatments.

Conclusion

Observation and execution of meaningful activities can enhance the effects of simply practicing those activities on occupational performance/satisfaction and corticospinal excitability poststroke.

Exploring the Multidimensional Participation of Adults Living in the Community in the Chronic Phase following Acquired Brain Injury

This exploratory study aimed to examine multiple aspects of the participation of adults in the chronic phase following acquired brain injury (ABI), considering different disability levels. Our study included 25 adults ≥6 months after ABI (predominantly stroke), living at home, without severe cognitive decline. Primary measures included the Canadian Occupational Performance Measure (subjective participation) and the Mayo-Portland Adaptability Inventory-4 Participation Index (objective participation). The results indicated subjective participation problems in all of the International Classification of Functioning, Disability and Health participation domains. In addition, objective participation was reported as most limited in the areas of leisure and recreational activities, residence, and employment. Both subjective and objective participation profiles varied according to the disability level except for the social and leisure areas, which were found to be similar across all subgroups. However, only partial compatibility was found between the subjective and objective participation aspects. To conclude, our findings indicated that chronic ABI survivors report a variety of subjective and objective participation concerns that varied according to their disability levels. Moreover, the incongruity between the participation aspects suggests that the level of limitation may not necessarily correspond to the importance of a particular participation area. This highlights the need for comprehensive assessments to determine unique individual participation profiles in order to facilitate client-centered interventions supporting the rehabilitation of community-dwelling ABI survivors.

Self-reported emotional health and social support but not executive function are associated with participation after stroke

BACKGROUND

Participation restrictions continue to be prevalent for community-dwelling stroke survivors. Research is needed to understand the associated post-stroke factors that limit or facilitate optimal participation and quality of life.

OBJECTIVES

To investigate emotional health, executive functioning (EF), and social support as predictors of participation restrictions post-stroke.

METHODS

Cross-sectional data collected from participants ≥ 6 months after mild stroke with and without aphasia (N = 114) were analyzed using three participation outcome measures: Reintegration to Normal Living Index (RNL), Activity Card Sort (ACS), and the Stroke Impact Scale (SIS) Version 2.0 Participation/Role Function domain. Predictor variables investigated were emotional health (SIS Emotion domain scores), EF (Delis Kaplan Executive Function System Trail Making Condition 4: DKEFS), social support (Medical Outcomes Study Social Support Survey: MOS-SSS), stroke severity (National Institutes of Health Stroke Scale: NIHSS), and education level.

RESULTS

Using multiple regression, these predictors accounted for 26.4% to 40% of the variance for the three participation outcomes. Emotional health was a significant independent predictor across all three measures. Social support was a significant predictor of participation as measured on the RNL. Executive function was not a significant predictor of participation when controlling for the other predictor variables.

CONCLUSIONS

Emotional health and social support should be considered as modifiable factors that could optimize meaningful participation and quality of life.

Body structure/function impairments and activity limitations of post-stroke that predict social participation: a systematic review

BACKGROUND

Stroke is the leading cause of death and disability in Brazil, and its prognostic indicators of social reintegration are not well established yet.

OBJECTIVE

To identify body structure/function impairments and activity limitations in post-stroke that predict social participation restrictions in the community.

METHODS

cohort studies were selected, involving adult post-stroke participants, which investigated body structure and function impairments or activity limitations of post-stroke individuals as predictors of social participation in the community. Studies that included individuals with subarachnoid hemorrhage, other neurological disorders and participants in long-term care facilities were excluded. The Newcastle-Ottawa quality assessment scale was applied to assess the methodological quality. The results were synthesized according to the found exposures, considering the used statistical models.

RESULTS

Eleven articles were included, with a total of 2,412 individuals, 58.4% men, 83.7% ischemic stroke. Seven exposures were assessed across studies, in which 10 studies assessed body structure and function exposures (stroke severity, cognitive, executive, emotional and motor function), and 8 studies assessed activity exposures (daily living activity and walking ability).

CONCLUSION

There is some evidence that stroke severity, mental and motor deficits, limitations in activities of daily living and the ability to walk after a stroke can predict social participation in the community. PROSPERO registration CRD42020177591.

Patient-Centered Outcomes in a Randomized Trial Investigating a Multimodal Prevention Program After Transient Ischemic Attack or Minor Stroke: The INSPiRE-TMS Trial

BACKGROUND

The INSPiRE-TMS trial (Intensified Secondary Prevention Intending a Reduction of Recurrent Events in Transient Ischemic Attack and Minor Stroke Patients) investigated effects of a multicomponent support program in patients with nondisabling stroke or transient ischemic attack. Although secondary prevention targets were achieved more frequently in the intensified care group, no significant differences were seen in rates of recurrent major vascular events. Here, we present the effects on prespecified patient-centered outcomes.

METHODS

In a multicenter trial, we randomized patients with modifiable risk factors either to the intensified or conventional care alone program. Intensified care was provided by stroke specialists and used feedback and motivational interviewing strategies (≥8 outpatient visits over 2 years) aiming to improve adherence to secondary prevention targets. We measured physical fitness, disability, cognitive function and health-related quality of life by stair-climbing test, modified Rankin Scale, Montreal Cognitive Assessment, and European Quality of Life 5 Dimension 3 Level during the first 3 years of follow-up.

RESULTS

Of 2072 patients (mean age: 67.4years, 34% female) assessed for the primary outcome, patient-centered outcomes were collected in 1,771 patients (877 intensified versus 894 conventional care group). Physical fitness improved more in the intensified care group (mean between-group difference in power (Watt): 24.5 after 1 year (95% CI, 5.5-43.5); 36.1 after 2 years (95% CI, 13.1-59.7) and 29.6 (95% CI, 2.0-57.3 after 3 years). At 1 year, there was a significant shift in ordinal regression analysis of modified Rankin Scale in favor of the intensified care group (common odds ratio, 1.23 [95% CI, 1.03-1.47]) but not after 2 (odds ratio, 1.17 [95% CI, 0.96-1.41]) or 3 years (odds ratio, 1.16 [95% CI, 0.95-1.43]) of follow-up. However, Montreal Cognitive Assessment and European Quality of Life 5 Dimension scores showed no improvement in the intensified intervention arm after 1, 2, or 3 years of follow-up.

CONCLUSIONS

Patients of the intensified care program group had slightly better results for physical fitness and modified Rankin Scale after 1 year, but none of the other patient-centered outcomes was significantly improved.

Self-Perceived ADL/IADL Function is Influenced by Residual Neurological Impairment, Aphasia, and Anxiety

BACKGROUND.

Self-perceptions of performance of activities of daily living (ADL) and instrumental activities of daily living (IADL) are reduced following stroke. Research investigating contributing factors is lacking.

PURPOSE.

We examined the extent to which aphasia status, neurological impairment and poststroke depression, and anxiety contribute to self-perceived ADL/IADL function.

METHOD.

Seventy-six community-dwelling individuals at least 6 months poststroke, 44 with and 32 without aphasia, participated in the cross-sectional study. The Stroke Impact Scale (SIS) ADL/IADL domain was the primary outcome measure with aphasia status, residual neurological impairment, depressive symptoms, and anxiety as predictor variables.

FINDINGS

Aphasia status, residual neurological impairment, and anxiety were independent predictors of self-perceived ADL/IADL function, together accounting for more than half the variance. Depression was not associated with ADL/IADL.

IMPLICATIONS.

Clinician awareness of the influence of anxiety on self-perceived ADL/IADL function, particularly for people with aphasia, may lead to future interventions that improve self-perceived ADL/IADL function.

Multidomain cognitive dysfunction after minor stroke suggests generalized disruption of cognitive networks

OBJECTIVE

Although small strokes typically result in "good" functional outcomes, significant cognitive impairment can occur. This longitudinal study examined a cohort of patients with minor stroke to determine the pattern of deficits, evolution over time, and factors associated with outcome.

METHODS

Patients admitted to the hospital with their first clinical minor stroke (NIH Stroke Scale [NIHSS] ≤ 10, absence of severe hemiparesis, aphasia, or neglect) were assessed at 1 month post-infarct, and a subset were followed over time (with 6- and 12-month evaluations). Composite scores at each time point were generated for global cognition, verbal memory, spatial memory, motor speed, processing speed, and executive function. Paired t-tests evaluated change in scores over time. Regression models identified factors associated with initial performance and better recovery.

RESULTS

Eighty patients were enrolled, evaluated at 1 month, and prospectively followed. The average age of the participants was 62.3 years, and mean education was 13.5 years. The average stroke volume was 6.6 cc; mean NIHSS score was 2.8. At 1 month, cognitive scores were below the normative range and > 1 standard deviation below the patient's peak ("recovery") score for every cognitive domain, strongly suggesting that they were well below patients' prestroke baselines. Forty-eight patients followed up at 6 months, and 39 at 12 months. Nearly all (98%) patients significantly improved in global cognition (averaged across domains) between 1 and 6 months. Between 6 and 12 months, recovery was variable. Higher education, occupational class, and Caucasian race were associated with higher recovery scores for most domains.

CONCLUSIONS

Cognitive impairment across multiple domains is common following minor stroke regardless of infarct location, suggesting a global process such as network dysfunction that improves over 6 months. Degree of recovery can be predicted using baseline factors.

Is the presence of home entrance steps associated with community participation of people with mobility impairments?

BACKGROUND

Little is known about how home entrances are related to community participation for people with mobility impairments.

OBJECTIVE

This investigation explored how the need to navigate steps at the entrance of a home affects the community participation levels of people with mobility impairments.

METHODS

This survey study used pre-measure data collected from three different samples. Participants were adults living independently in the community aged 18-94 years old who self-reported having a mobility impairment. Measures included the Brief Community Engagement Questionnaire to examine potential differential effects on the number of non-discretionary trips people make into the community (e.g., getting groceries, medications) versus the number of discretionary activities (e.g., socializing outside the home) people reported over seven days.

RESULTS

People with mobility impairments were less likely to report a stepped entrance than people without MI, but when the entrance they use the most had steps they reported significantly higher exertion to use the entrance. The presence of steps had no effect on non-discretionary trips (p = .74), but was associated with 49% (p < .01) fewer discretionary activities reported by people with mobility impairment relative to those without MI.

CONCLUSION

Steps at the home entrance of people with mobility impairment may be an important mediating factor in their level of participation. When researchers and practitioners evaluate interventions that aim to increase community participation of people with mobility impairment, they should control for the presence of steps at their home entrance.

Apathy and residual neurological impairment are associated with community reintegration after mild stroke

This study investigated the influence of apathy and positive social support on community reintegration after stroke. A prospective, correlational, cross-sectional design was used. 85 community dwelling participants with and without aphasia were included (≥ 18 years of age, first stroke, ≥ 6 months post-stroke). The Reintegration to Normal Living Index (RNL) measured poststroke participation. The Apathy Evaluation Scale (AES) and Positive Social Interaction domain of the Medical Outcomes Study Social Support Survey assessed apathy and social support respectively. NIH Stroke Scale measured residual neurological impairment. Apathy, social support, and stroke impairment together were strongly associated with the RNL and accounted for 51% of total variance in the RNL. The AES and NIHSS were independent predictors of the RNL, though positive social interaction failed to reach significance. Persons with and without apathy differed significantly on the RNL. Therefore, stroke rehabilitation should address apathy as a potential target for intervention. Future research should determine factors that mediate the relationship between poststroke apathy and community reintegration.

Cognitive impairment in two subtypes of a single subcortical infarction

Background:

Single subcortical infarction (SSI) is caused by two main etiological subtypes, which are branch atheromatous disease (BAD) and cerebral small vessel disease (CSVD)-related SSI. We applied the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ), the Shape Trail Test (STT), and the Stroop Color and Word Test (SCWT) to investigate the differences in cognitive performance between these two subtypes of SSI.

Methods:

Patients with acute SSIs were prospectively enrolled. The differences of MoCA-BJ, STT, and SCWT between the BAD group and CSVD-related SSI group were analyzed. A generalized linear model was used to analyze the associations between SSI patients with different etiological mechanisms and cognitive function. We investigated the correlations between MoCA-BJ, STT, and SCWT using Spearman's correlation analysis and established cut-off scores for Shape Trail Test A (STT-A) and STT-B to identify cognitive impairment in patients with SSI.

Results:

This study enrolled a total of 106 patients, including 49 and 57 patients with BAD and CSVD-related SSI, respectively. The BAD group performances were worse than those of the CSVD-related SSI group for STT-A (83 [60.5–120.0] vs. 68 [49.0–86.5], P = 0.01), STT-B (204 [151.5–294.5] vs. 153 [126.5–212.5], P = 0.015), and the number of correct answers on Stroop-C (46 [41–49] vs. 49 [45–50], P = 0.035). After adjusting for age, years of education, National Institutes of Health Stroke Scale and lesion location, the performance of SSI patients with different etiological mechanisms still differed significantly for STT-A and STT-B.

Conclusions:

BAD patients were more likely to perform worse than CSVD-related SSI patients in the domains of language, attention, executive function, and memory. The mechanism of cognitive impairment after BAD remains unclear.

Assessment of responsiveness of four hand-related scales in stroke patients

Self-reporting scales are commonly utilized in determining appropriate treatment strategies and follow-up in hand-related disorders. Responsiveness is described as the ability of a scale to detect clinically significant changes. We aimed to evaluate responsiveness of Michigan Hand Outcomes Questionnaire (MHQ), Duruöz Hand Index (DHI), Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and ABILHAND questionnaire in stroke patients. Fifty-one stroke patients were assessed in this descriptive study. Participants received conventional stroke rehabilitation program consisting of 30 sessions. Brunnstrom stages of the stroke patients were recorded before and after treatment. MHQ, DHI, DASH, ABILHAND questionnaire and patient satisfaction scores were filled in by participants before and after the conventional rehabilitation program. Significant improvements were found in MHQ, DHI, DASH, ABILHAND, patient satisfaction scores and Brunnstrom motor recovery stages after the rehabilitation program (p < 0.001). Responsiveness values of the scales were calculated as MHQ (effect size (ES) = - 0.74; standardized response mean (SRM) = - 1.25), DHI (ES = 0.64; SRM = 1.22), DASH (ES = 0.71; SRM = 1.01), and ABILHAND (ES = - 0.55; SRM = - 1.22). Our study revealed that MHQ, DHI, DASH and ABILHAND are responsive scales in detecting treatment-related changes in stroke patients. MHQ, DHI, DASH and ABILHAND can be used in the evaluation of treatment responses in stroke patients.

Cognitive Testing During Mild Acute Ischemic Stroke Predicts Long-Term Return to Work

OBJECTIVES

Many survivors of a mild ischemic stroke do not return to work or driving. Cognitive testing is commonly done to assess long-term cognitive impairment after stroke. Inpatient cognitive testing during the acute period of ischemic stroke may also be a predictor for workforce reengagement and functional outcome.

MATERIALS AND METHODS

At our comprehensive stroke center, we prospectively enrolled previously working adults < 65 years old who were diagnosed with first-ever ischemic stroke, had a prestroke modified Rankin Scale (mRS) ≤ 1 and NIHSS ≤ 3. Testing performed within 1 week of stroke included the Montreal Cognitive Assessment (MOCA), Clock Drawing Test (CDT), Trail Making Tests A and B, Backward Digit Span Test, and Hospital Anxiety and Depression Scale (HADS). Other data obtained included age, gender, years of education, occupation, stroke location, stroke laterality, and presence of white matter disease on imaging. Outcome measures assessed at 3 months, 6 months, and 12 months post-stroke included return to work, return to driving, and mRS. In a logistic regression analysis, we performed both univariate and multivariate analyses. Multivariate analysis was completed on variables with p-value ≤ 0.05 in the univariate analysis.

RESULTS

Of 39 total stroke patients enrolled and tested (median [IQR] age 55 [46-60] years; 77.5% male; 22.5% female), 36 completed 3-month follow up, of which 58% returned to work, 78% returned to driving, and 72% had mRS of 0-1. In multivariate analysis, a single point increase in the clock drawing task score increased the odds of return to work by 3.79 (95% CI, 1.10-14.14) and return to driving by 6.74 (95% CI, 1.22-37.23) at 3 months. MOCA and HADS were both associated with mRS ≤ 1. MOCA was associated with return to work at 6 months and CDT was associated with return to work at 12 months.

CONCLUSION

Cognitive testing with CDT and MOCA in the acute period after ischemic stroke may predict common patient goals post stroke, including return to work, driving, and independence. These tools can potentially be used for prognosis and identifying those who may benefit from further interventions.

Effectiveness of the Functional and Cognitive Occupational Therapy (FaCoT) Intervention for Improving Daily Functioning and Participation of Individuals with Mild Stroke: A Randomized Controlled Trial

BACKGROUND

Mild stroke can cause subtle cognitive-behavioral symptoms, which although might be hidden, can restrict community reintegration and participation. Cognitive rehabilitation programs exist for stroke but not specifically for mild stroke and the research evidence varies. The Functional and Cognitive Occupational Therapy (FaCoT) intervention was developed specifically for this population.

OBJECTIVE

To examine the effectiveness of FaCoT intervention for improving daily functioning and participation compared with standard care.

METHOD

A single blind randomized controlled trial with assessments pre (T1), post (T2) and 3-month follow-up (T3). Individuals in the FaCoT group received 10 weekly sessions practicing cognitive and behavioral strategies. The Canadian Occupational Performance Measure (COPM) was the primary outcome measure, IADL-questionnaire, Reintegration to Normal Living questionnaire (RNL) were secondary measures.

RESULTS

In total, 66 community-dwelling individuals with mild stroke were randomly allocated to FaCoT (n = 33, mean (SD) age 64.6 (8.2), 33% women), or control group (n = 33, mean (SD) age 64.4 (10.8), 45% women). Time X Group interaction effects were found for the COPM performance (F(1.4,90.3) = 11.75, p < 0.000) and satisfaction (F(1.5,96.8) = 15.70, p < 0.000), with large effect size values. Significant between-group effects were found for RNL (F = 10.02, p < 0.002, ɳP2 = 0.13). Most participants in FaCoT achieved a clinically important difference in COPM between T1-T2, T1-T3, and in RNL between T1 to T3 compared with the control group.

CONCLUSIONS

FaCoT intervention is effective to improve daily functioning, participation and satisfaction of individuals with mild stroke compared with standard care, therefore FaCoT should be implemented in community rehabilitation settings.

Using Multicontext Approach to Improve Instrumental Activities of Daily Living Performance after a Stroke: A Case Report

Cognitive deficits constitute one of the greatest challenges for independence achievement after a stroke. This paper provides an in depth view of the application of the Multicontext approach within routine Occupational Therapy care for a 41-year-old who demonstrated limited participation in activities of daily living as a consequence of executive function impairments and limited self-awareness. Results indicated improved online self-awareness, strategy use and functional performance, however, no changes were observed on a standard Awareness Questionnaire. This suggests that awareness within activities may be more important in contributing to effective strategy use and functional performance compared to verbal acknowledgment in an interview. Results also support the feasibility of the Multicontext approach within inpatient settings in Argentina.

Determinants of life satisfaction among stroke survivors 1 year post stroke

ABSTRACT

Stroke is the major leading cause of death and severe long-term disability worldwide. The consequences of stroke, aside from diminished survival, have a significant impact on an individual's capability in maintaining self-autonomy and life satisfaction (LS). Thus, this study aimed to assess LS and other specific domains of LS in stroke survivors following their first-ever stroke, and to describe the relationship using socio-demographic and stroke-related variables.This study recruited 376 stroke survivors (244 men and 132 women, mean age: 57 years) 1 year following stroke. Data on participants' LS (measured using the Life Satisfaction Questionnaire [LiSat-11]), socio-demographics, and stroke-related variables were collected.Univariate analysis showed that LS and the 10 specific domains were not associated with the patients' gender or stroke type; however, age at onset, marital status, and vocational situation were significantly associated with some domains in LiSat-11 (Spearman's rho = 0.42-0.87; all P < 0.05). Logistic regression revealed that verbal and cognitive dysfunction were the most negative predictors of LS (odds ratio 4.1 and 3.7, respectively).LS is negatively affected in stroke survivors 1 year post onset. The results indicate that recovering social engagement is a positive predictor of higher LS in stroke survivors. More importantly, the findings revealed that cognitive and verbal dysfunctions were the most prominent negative predictors of the overall gross level of LS. Multidisciplinary rehabilitation for stroke survivors is therefore critical.

Usability, Usefulness, and Acceptance of a Novel, Portable Rehabilitation System (mRehab) Using Smartphone and 3D Printing Technology: Mixed Methods Study

BACKGROUND

Smart technology use in rehabilitation is growing and can be used remotely to assist clients in self-monitoring their performance. With written home exercise programs being the commonly prescribed form of rehabilitation after discharge, mobile health technology coupled with task-oriented programs can enhance self-management of upper extremity training. In the current study, a rehabilitation system, namely mRehab, was designed that included a smartphone app and 3D-printed household items such as mug, bowl, key, and doorknob embedded with a smartphone. The app interface allowed the user to select rehabilitation activities and receive feedback on the number of activity repetitions completed, time to complete each activity, and quality of movement.

OBJECTIVE

This study aimed to assess the usability, perceived usefulness, and acceptance of the mRehab system by individuals with stroke and identify the challenges experienced by them when using the system remotely in a home-based setting.

METHODS

A mixed-methods approach was used with 11 individuals with chronic stroke. Following training, individuals with stroke used the mRehab system for 6 weeks at home. Each participant completed surveys and engaged in a semistructured interview. Participants' qualitative reports regarding the usability of mRehab were integrated with their survey reports and quantitative performance data.

RESULTS

Of the 11 participants, 10 rated the mRehab system between the 67.5th and 97.5th percentile on the System Usability Scale, indicating their satisfaction with the usability of the system. Participants also provided high ratings of perceived usefulness (mean 5.8, SD 0.9) and perceived ease of use (mean 5.3, SD 1.5) on a 7-point scale based on the Technology Acceptance Model. Common themes reported by participants showed a positive response to mRehab with some suggestions for improvements. Participants reported an interest in activities they perceived to be adequately challenging. Some participants indicated a need for customizing the feedback to be more interpretable. Overall, most participants indicated that they would like to continue using the mRehab system at home.

CONCLUSIONS

Assessing usability in the lived environment over a prolonged duration of time is essential to identify the match between the system and users' needs and preferences. While mRehab was well accepted, further customization is desired for a better fit with the end users.

How Well Does the Brief Interview for Mental Status Identify Risk for Cognition Mediated Functional Impairment in a Community Sample?

OBJECTIVE

To determine the adequacy of the Brief Interview for Mental Status (BIMS) compared with other screening tools in identifying individuals with limitations in functional cognition and instrumental activities of daily living (IADL).

DESIGN

Cross-sectional observational study.

SETTING

Midsized midwestern city.

PARTICIPANTS

We assessed a convenience sample of community dwelling individuals (N=197) aged 55 years and older who were living independently.

MAIN OUTCOME MEASURES

Participant scores on the BIMS, Mini-Cog, Menu Task, and Montreal Cognitive Assessment (MoCA) were compared with the Performance Assessment of Self-Care Skills Checkbook Balancing and Shopping tasks (PCST), which are known to predict impairment in complex IADLs associated with a diagnosis of mild cognitive impairment. Multiple logistic regression analyses controlling for participant demographics, as well as sensitivity and specificity, were computed for each screening measure using the PCST as the criterion measure.

RESULTS

The Mini-Cog, Menu Task, and MoCA identified 25.89%, 32.49%, and 47.21% more individuals, respectively, as impaired than the BIMS. In multiple logistical regression analyses, the BIMS correctly identified 58% of those impaired on the PCST. However, each of the alternate screening measures correctly identified at least 70% of individuals as impaired on the PCST.

CONCLUSIONS

In this community sample, the BIMS was insensitive to subtle impairments with the potential to compromise community living, suggesting that the BIMS may be inappropriate for use outside nursing home settings.

Emotion recognition impairments and social well-being following right-hemisphere stroke

Accurately recognizing and responding to the emotions of others is essential for proper social communication and helps bind strong relationships that are particularly important for stroke survivors. Emotion recognition typically engages cortical areas that are predominantly right-lateralized including superior temporal and inferior frontal gyri - regions frequently impacted by right-hemisphere stroke. Since prior work already links right-hemisphere stroke to deficits in emotion recognition, this research aims to extend these findings to determine whether impaired emotion recognition after right-hemisphere stroke is associated with worse social well-being outcomes. Eighteen right-hemisphere stroke patients (≥6 months post-stroke) and 21 neurologically healthy controls completed a multimodal emotion recognition test (Geneva Emotion Recognition Test - Short) and reported engagement in social/non-social activities and levels of social support. Right-hemisphere stroke was associated with worse emotion recognition accuracy, though not all patients exhibited impairment. In line with hypotheses, emotion recognition impairments were associated with greater loss of social activities after stroke, an effect that could not be attributed to stroke severity or loss of non-social activities. Impairments were also linked to reduced patient-reported social support. Results implicate emotion recognition difficulties as a potential antecedent of social withdrawal after stroke and warrant future research to test emotion recognition training post-stroke.

Psychometric properties of measures of upper limb activity performance in adults with and without spasticity undergoing neurorehabilitation-A systematic review

INTRODUCTION

This systematic review appraises the measurement quality of tools which assess activity and/or participation in adults with upper limb spasticity arising from neurological impairment, including methodological quality of the psychometric studies. Differences in the measurement quality of the tools for adults with a neurological impairment, but without upper limb spasticity, is also presented.

METHODS

29 measurement tools identified in a published review were appraised in this systematic review. For each identified tool, we searched 3 databases (Medline, Embase, CINAHL) to identify psychometric studies completed with neurorehabilitation samples. Methodological quality of instrument evaluations was assessed with use of the Consensus-based Standards for the Selection of Health Status Measurement Instruments (COSMIN) checklist. Synthesis of ratings allowed an overall rating of the psychometric evidence for each measurement tool to be calculated.

RESULTS

149 articles describing the development or evaluation of psychometric properties of 22 activity and/or participation measurement tools were included. Evidence specific to tool use for adults with spasticity was identified within only 15 of the 149 articles and provided evidence for 9 measurement tools only. Overall, COSMIN appraisal highlighted a lack of evidence of measurement quality. Synthesis of ratings demonstrated all measures had psychometric weaknesses or gaps in evidence (particularly for use of tools with adults with spasticity).

CONCLUSIONS

The systematic search, appraisal and synthesis revealed that currently there is insufficient measurement quality evidence to recommend one tool over another. Notwithstanding this conclusion, newer tools specifically designed for use with people with neurological conditions who have upper limb spasticity, have emergent measurement properties that warrant further research.

A randomised controlled trial of expressive arts-based intervention for young stroke survivors

BACKGROUND

Stroke causes lasting brain damage that has numerous impacts on the survivor's physical, psychosocial, and spiritual well-being. Young survivors (< 65 years old) tend to suffer more because of their longer overall survival time. Expressive arts-based intervention is considered a holistic approach for stroke rehabilitation because it allows participants to express their thoughts and emotions through the arts. The group environment also promotes mutual support among participants. The creative art-making process helps expand participants' creativity and imagination as well as promote a sense of aesthetic appreciation. Previous studies have shown the effectiveness of the arts-based intervention in managing stroke and its psychosocial-spiritual comorbidities. Nevertheless, a systematic study has not been conducted, including in young survivors. This trial plans to investigate the effectiveness of an expressive arts-based intervention on bio-psychosocial-spiritual outcomes in young Chinese stroke survivors.

METHODS/DESIGN

A single-blind, two-arm cluster randomised control trial with a waitlist control design will be adopted. One hundred and fifty-four stroke survivors, aged 18-64 years with modified Rankin Scale scores of 1-4, will be screened and randomised to either an expressive arts-based intervention group or a treatment-as-usual waitlist control group. The intervention group will receive a 90-min session once a week for a total of 8 weeks. All participants will be assessed three times: at baseline, 8 weeks, and 8 months after the baseline. Study outcomes include measures of depression and anxiety, perceived stress, perceived social support, hope, spiritual well-being, quality of life, salivary cortisol, blood pressure, and heart rate.

DISCUSSION

This study is expected to contribute to the current knowledge on the effectiveness of an arts-based intervention on the holistic wellness of young stroke survivors. The findings will help stroke survivors and healthcare professionals make better choices in selecting practices that will yield maximum benefits, satisfaction, adherence, and sustainability. In addition, the examination of the relationships between bio-psychosocial-spiritual variables will help contribute to the development of holistic care for the survivors.

Understanding activity participation 3-months after stroke: a mixed methodology study

PURPOSE

To investigate stroke survivors' activity participation 3-months after stroke, reasons for activity participation and the change in reason for activity participation.

METHOD

Thirty stroke survivors were administered the Activity Card Sort-Australia concurrent with a semi-structured interview about their activity participation. Data were analyzed using descriptive statistics and spiral content analysis.

RESULTS

Participants had returned, in part, to 96% of their previous leisure, social/educational and household activities 3-months after-stroke; retaining more sedentary and home-based activities but fewer physically demanding and community-based activities. Thirteen participants described a change in their reasons for their activity participation. Personal, environmental and temporal dimensions explained these reasons for activity participation, as well as the changes in reason for activity participation. Full activity participation involved participants' orchestrating a dynamic mix of fulfilling their personal desires according to their current physical, mental and emotional capacity; their social, organizational and physical environmental demands and obligations; and their routines, available time and future plans.

CONCLUSION

Qualitative interviews extend our understanding of the process of returning to participation in life activities and occupations following stroke to reveal that it involves the stroke survivor in a dynamic adaptation process of synchronizing personal, environmental and temporal dimensions in their daily lives.IMPLICATIONS FOR REHABILITATIONRehabilitation professionals need to recognize the unique knowledge and ability stroke survivors have to manage their capacities, activities, occupations and environments.Client-centered practice involving true collaborative partnerships are needed to ensure stroke survivors return more satisfactorily to their activities and occupations.Rehabilitation professionals need to continually consider the ongoing changing relationships that occur between the person, their capacities, social, organizational and physical environments, and the person's activity/occupational participation during recovery from stroke.Returning to full activity/occupational participation after stroke is a dynamic and continuous process.Rehabilitation needs to be provided in different forms at different stages beyond the immediate post-stroke time so that stroke survivors benefit from the "right rehabilitation" at the "right time" throughout their recovery journey.

Cross-cultural adaptation of Life Satisfaction Checklist-11 among persons with stroke in China: A reliability and validity study

OBJECTIVE

The aim of the present study was to develop a cross-cultural adaptation and to evaluate the validity and reliability of a Chinese version of the LiSat-11 test.

METHODS

LiSat-11 was translated into Chinese according to standardized procedures. A cross-sectional descriptive study was conducted to examine its reliability and validity, in accordance to COnsensus-based Standards for the election of health Measurements Instruments guidelines, among persons with stroke approximately 3 years after their discharge from rehabilitation. Participants completed the LiSat-11, 36-Item Short-Form Health Survey (SF-36), National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), Barthel Index (BI) and Hospital Anxiety and Depression Scale (HADS). To examine the test-retest reliability, thirty of these participants completed LiSat-11 again after 2 weeks.

RESULTS

In total, 60 persons with stroke were recruited. The Chinese version of LiSat-11 demonstrated good internal consistency with Cronbach's alphas at 0.82. Ceiling effects were found in five of the eleven items of LiSat-11, and there was a floor effect in one item. LiSat-11 had moderate to high correlations with SF-36 with Spearman's correlation coefficient (rho) ranging from 0.44 to 0.73 (p < 0.01) in a concurrent validity test, and high correlations were also found between LiSat-11 and HADS-A/D in a convergent validity test with rho = -0.63/-0.67 (p < 0.01). Low correlations with NIHSS, BI and mRS were found in a divergent validity test, rho = -0.25, 0.17 and -0.26, respectively.

CONCLUSION

The current study verified that the translated Chinese version of the Life Satisfaction Checklist-11 is a reliable and valid tool for measuring the life satisfaction of persons with chronic stroke.

Screening and patient-tailored care for emotional and cognitive problems compared to care as usual in patients discharged home after ischemic stroke (ECO-stroke): a protocol for a multicenter, patient-blinded, cluster randomized controlled trial

Background

Ischemic stroke patients with a good outcome in terms of motor functioning and communication are likely to be discharged home without further rehabilitation. A significant number of these patients experience cognitive and emotional problems resulting in lower quality of life and decreased participation in society. This paper presents the protocol of a study examining the clinical effectiveness, cost-effectiveness and implementation of an intervention focused on screening and patient-tailored care for cognitive and emotional problems as compared to usual care in patients discharged home after ischemic stroke.

Methods / design

A multicenter, patient-blinded, cluster randomized controlled trial will be performed. Centers will be randomized (1:1) to the intervention group or the usual care group. Patients (> 18 years old) with a neurological confirmed diagnosis of ischemic stroke who can be discharged home without follow-up treatment at an outpatient rehabilitation clinic will be included. In the intervention group, patients will receive a short, individualized, semi-structured consultation by specialized nurses in addition to usual care. This consultation includes 1) screening for cognitive and emotional problems, 2) screening for restrictions in participation, 3) promotion of self-management strategies and 4) a decision tool for referral to rehabilitation services. The intervention will be performed approximately 6 weeks after the stroke at the neurology outpatient clinics and will take approximately 60 min. The control group will receive care as usual. Both groups will be followed-up at 6 weeks, 3 months and 12 months after stroke. The primary outcome will be the level of participation measured with the Restriction subscale of the Utrecht Scale for Evaluation of Rehabilitation on the level of Participation (USER-Participation-R) at 12 months. A cost-effectiveness analysis and process evaluation will be performed alongside.

Discussion

This trial is the first to evaluate clinical effectiveness, cost-effectiveness and implementation of screening and patient-tailored care for cognitive and emotional problems compared to care as usual in patients discharged home after ischemic stroke. Potentially, this will improve the outcomes for patients with frequently occurring cognitive and emotional problems after stroke.

Look closer: The multidimensional patterns of post-stroke burden behind the modified Rankin Scale

Background

The utility-weighted modified Rankin Scale, representing patient perspectives of quality of life, is a newly proposed measure to improve the interpretability of the modified Rankin Scale. Despite obvious advantages, such weighting imperfectly reflects the multidimensional patterns of post-stroke burden.

Aims

To investigate multidimensional patterns of post-stroke burden formed by individual domains of Assessment of Quality of Life and Barthel Index for each modified Rankin Scale category.

Methods

In the A Very Early Rehabilitation Trial (n = 2104), modified Rankin Scale scores and modified Rankin Scale-stratified Barthel Index scores of Self-care and Mobility, and Assessment of Quality of Life scores of Independent Living, Senses, Mental Health and Relationships were collected at three months. The multivariate relationship between individual Assessment of Quality of Life and Barthel Index domains, and modified Rankin Scale was investigated using random effects linear regression models with respective interaction terms.

Results

Of 2104 patients, simultaneously collected Assessment of Quality of Life, Barthel Index and modified Rankin Scale scores at three months were available in 1870 patients. While individual Assessment of Quality of Life and Barthel Index domain scores decreased significantly as modified Rankin Scale increased (p < 0.0001), the patterns of decrease differed by domains (p < 0.0001). Patients with modified Rankin Scale 0–1 had the largest post-stroke burden in the Mental Health and Relationship domains, while patients with modified Rankin Scale >3 showed the greatest burden in Independent Living, Mobility and Self-care domains.

Conclusions

Across the modified Rankin Scale, individual domains are varyingly impacted demonstrating unique patterns of post-stroke burden, which facilitates appropriate assessment, articulation and interpretation of the modified Rankin Scale and utility-weighted modified Rankin Scale.

Inconsistent Classification of Mild Stroke and Implications on Health Services Delivery

OBJECTIVE

To conduct a scoping review on classifications of mild stroke based on stroke severity assessments and/or clinical signs and symptoms reported in the literature.

DATA SOURCES

Electronic searches of PubMed, PsycINFO (Ovid), and Cumulative Index to Nursing and Allied Health (CINAHL-EBSCO) databases included keyword combinations of mild stroke, minor stroke, mini stroke, mild cerebrovascular, minor cerebrovascular, transient ischemic attack, or TIA.

STUDY SELECTION

Inclusion criteria were limited to articles published between January 2003 and February 2018. Inclusion criteria included studies (1) with a definition of either mild or minor stroke, (2) written in English, and (3) with participants aged 18 years and older. Animal studies, reviews, dissertations, blogs, editorials, commentaries, case reports, newsletters, drug trials, and presentation abstracts were excluded.

DATA EXTRACTION

Five reviewers independently screened titles and abstracts for inclusion and exclusion criteria. Two reviewers independently screened each full-text article for eligibility. The 5 reviewers checked the quality of the included full-text articles for accuracy. Data were extracted by 2 reviewers and verified by a third reviewer.

DATA SYNTHESIS

Sixty-two studies were included in the final review. Ten unique definitions of mild stroke using stroke severity assessments were discovered, and 10 different cutoff points were used. The National Institutes of Health Stroke Scale was the most widely used measure to classify stroke severity. Synthesis also revealed variations in classification of mild stroke across publication years, time since stroke, settings, and medical factors including imaging, medical indicators, and clinical signs and symptoms.

CONCLUSIONS

Inconsistencies in the classification of mild stroke are evident with varying use of stroke severity assessments, measurement cutoff scores, imaging tools, and clinical or functional outcomes. Continued work is necessary to develop a consensus definition of mild stroke, which directly affects treatment receipt, referral for services, and health service delivery.

Self-Perception of Physical Function Contributes to Participation in Cognitively- and Physically-Demanding Activities After Stroke

Background: Persons with and without aphasia experience decreased participation in meaningful activities post-stroke that result in reduced autonomy and poorer quality of life. Physical, cognitive, and/or communication deficits are prevalent post-stroke and many activities given up are purported to require high levels of communicative, cognitive, or physical skill. However, the relationship between deficits after stroke and participation in life activities that appear to require high skill levels in these three areas has not been investigated fully.

Objectives: The objectives of this study are to: (1) determine differences in reported participation in communicatively-, cognitively-, or physically-demanding activities in persons after stroke with and without aphasia living in the community, and to (2) investigate whether performance on commonly used self-perception assessments of these three areas predicts reported participation in activities requiring higher levels of skill in these domains.

Methods: In a cross-sectional design, 82 individuals at least 6 months post-stroke with (N = 34) and without aphasia (N = 48) were administered a battery of neuropsychological and participation-based assessments. Supported communication techniques maximized inclusion of individuals with aphasia. A series of regression analyses investigated the relationship between self-perceived communicative, cognitive, and physical functioning and reported participation in activities post-stroke that required high amounts of skilled function in these areas.

Results: People with and without aphasia did not differ in terms of the percentage retained in communicatively-, cognitively-, or physically-demanding activities. All individuals retained higher levels of participation in communicatively- and cognitively-demanding activities (at least 60% retained), compared to participation inphysically-demanding activities (about 50% retained). The strongest predictor for retaining participation in two of the three domains of activities was self-perception of physical function, though much of the variance remained unexplained. Self-perception of communication was not related to participation retention in any of the three domains.

Significance of Impact: Rehabilitation professionals should be aware of the impact that a variety of communicative, cognitive, and physical factors may have on participation post-stroke. Self-perceptions of impairments in communication and cognition may not directly predict participation in activities requiring high levels of communicative and/or cognitive skill, at least for those with mild impairment, even though activities requiring those skills are given up or done less after stroke.

Balance and Gait After First Minor Ischemic Stroke in People 70 Years of Age or Younger: A Prospective Observational Cohort Study

BACKGROUND

Two-thirds of patients with stroke experience only mild impairments in the acute phase, and the proportion of patients <70 years is increasing. Knowledge about balance and gait and predictive factors are scarce for this group.

OBJECTIVE

The objective of this study was to explore balance and gait in the acute phase and after 3 and 12 months in patients ≤70 years with minor ischemic stroke (National Institutes of Health Stroke Scale score ≤3). This study also explored factors predicting impaired balance after 12 months.

DESIGN

This study was designed as an explorative longitudinal cohort study.

METHODS

Patients were recruited consecutively from 2 stroke units. Balance and gait were assessed with the Mini-Balance Evaluation Systems Test (Mini-BESTest), Timed Up and Go, and preferred gait speed. Predictors for impaired balance were explored using logistic regression.

RESULTS

This study included 101 patients. Mean (SD) age was 55.5 (11.4) years, 20% were female, and mean (SD) National Institutes of Health Stroke Scale score was 0.6 (0.9) points. The Mini-BESTest, gait speed, and Timed Up and Go improved significantly from the acute phase to 3 months, and gait speed also improved from 3 to 12 months. At 12 months, 26% had balance impairments and 33% walked slower than 1.0 m/s. Poor balance in the acute phase (odds ratio = 0.92, 95% confidence interval = 0.85-0.95) was the only predictor of balance impairments (Mini-BESTest score ≤22) at 12 months poststroke.

LIMITATIONS

Limitations include lack of information about pre-stroke balance and gait impairment and poststroke exercise. Few women limited the generalizability.

CONCLUSION

This study observed improvements in both balance and gait during the follow-up; still, about one-third had balance or gait impairments at 12 months poststroke. Balance in the acute phase predicted impaired balance at 12 months.

Vascular-brain Injury Progression after Stroke (VIPS) study: concept for understanding racial and geographic determinants of cognitive decline after stroke

Cognitive impairment and dementia (CID) are major public health problems with substantial personal, social, and financial burdens. African Americans are at a heightened risk for Vascular Cognitive Impairment (VCI) compared to European Americans. Recent lines of evidence also suggest a high burden of Post-stroke VCI among indigenous Africans. A better understanding of the cause(s) of the racial disparity in CID, specifically VCI, is needed in order to develop strategies to reduce it. We propose and discuss the conceptual framework for a unique tri-population, trans-continental study titled The Vascular brain Injury Progression after Stroke (VIPS) study. The overarching objective of the VIPS Study will be to explore the interplay of multiple factors (racial, geographical, vascular, lifestyle, nutritional, psychosocial and inflammatory) influencing the level and trajectory of post-stroke cognitive outcomes and examine whether differences between indigenous Africans, African Americans and European Americans exist. We hypothesize that differences which might be due to racial factors will be observed in African Americans versus European Americans as well as Indigenous Africans versus European Americans but not in African Americans versus Indigenous Americans; differences due to geographical factors will be observed in Indigenous Americans versus African Americans and Indigenous Africans versus European Americans but not in African Americans versus European Americans. This overarching objective could be accomplished by building upon existing National Institutes of Health investments in the REasons for Geographical And Racial Differences in Stroke (REGARDS) study (based in the United States of America) and the Stroke Investigative Research and educational Network (SIREN) study (based in Sub-Saharan Africa).

Pre-existing Comorbidity Burden and Patient Perceived Stroke Impact

BACKGROUND

Pre-existing comorbidities can compromise recovery post-stroke. However, the association between comorbidity burden and patient-rated perceived impact has not been systematically investigated. To date, only observer-rated outcome measures of function, disability, and dependence have been used, despite the complexity of the impact of stroke on an individual.

AIM

Our aim was to explore the association between comorbidity burden and patient-rated perceived impact and overall recovery, within the first-year post-stroke, after adjusting for stroke severity, age, and sex.

METHODS

The sample comprised 177 stroke survivors from 18 hospitals throughout Australia and New Zealand. Comorbidity burden was calculated using the Charlson Comorbidity Index. Perceived impact and recovery were measured by the Stroke Impact Scale index and Stroke Impact Scale overall recovery scale. Quantile regression models were applied to investigate the association between comorbidity burden and perceived impact and recovery.

RESULTS

Significant negative associations between the Charlson Comorbidity Index and the Stroke Impact Scale index were found at three months. At the .25 quantile, a one-point increase on the Charlson Comorbidity Index was associated with 6.80-points decrease on the Stroke Impact Scale index (95%CI: -11.26, -2.34; p = .003). At the median and .75 quantile, a one-point increase on the Charlson Comorbidity Index was associated, respectively, with 3.58-points decrease (95%CI: -5.62, -1.54; p = .001) and 1.76-points decrease (95%CI: -2.80, -0.73; p = .001) on the Stroke Impact Scale index. At 12 months, at the .25 and .75 quantiles, a one-point increase on the Charlson Comorbidity Index was associated, respectively, with 6.47-points decrease (95%CI: -11.05, -1.89; p = .006) and 1.26-points decrease (95%CI: -2.11, -0.42; p = .004) on the Stroke Impact Scale index. For the Stroke Impact Scale overall recovery measure, significant negative associations were found only at the median at three months and at the .75 quantile at 12 months.

CONCLUSION

Comorbidity burden is independently associated with patient-rated perceived impact within the first-year post-stroke. The addition of patient-rated impact measures in personalized rehabilitation may enhance the use of conventional observer-rated outcome measures.

Impairments in spatial navigation during walking in patients 70 years or younger with mild stroke

Background: Spatial navigation, the ability to determine and maintain a route from one place to another, is needed for independence in everyday life. Knowledge about impairments in spatial navigation in people with mild stroke is scarce.Objectives: To explore impairments in spatial navigation in patients ≤70 years after first-ever mild ischemic stroke (NIHSS≤3) and to explore which variables are associated with these impairments 12 months later.Methods: Patients were examined in the acute phase, and after 3 and 12 months. To assess impairments in spatial navigation, we used the Floor Maze Test (FMT), with time and FMT-errors as outcomes. Patients' perceived navigational skills were collected using self-report. Logistic regression was used to explore which variables (sociodemographic data, stroke characteristics, cognition, and mobility) were associated with impaired navigation ability.Results: Ninety-seven patients (20 females) were included. The mean (SD) age was 55.5 (11.4) years. Timed FMT improved significantly from the acute phase to 12 months (p = <.001). At 12 months, 24 (24.7%) of the participants walked through the maze with errors, and 22 (22.7%) reported spatial navigational problems. The Trail Making Test (TMT)-B was the only variable from the acute phase associated with FMT-errors at 12 months, and being female was the only variable associated with self-reported navigational problems at 12 months.Conclusion: Nearly one in four patients experienced spatial navigation problems 12 months after a mild stroke. Executive function (TMT-B), measured in the acute phase, was associated with navigational impairments (FMT-errors) at 12 months, and being female was associated with self-reported navigational problems.
