Correlation between the Activities of Daily Living of Stroke Patients in a Community Setting and Their Quality of Life

The evaluation of daily activity questionnaire for stroke survivors: cross-cultural adaptation, content validity and digitisation

OBJECTIVE

The study's objective was to culturally adapt and digitise the Evaluation of Daily Activity Questionnaire (EDAQ), originally designed for rheumatoid arthritis and various other musculoskeletal conditions, creating a version for stroke survivors (EDAQ-SS). This adaptation also aimed to develop a comprehensive electronic Patient Reported Outcome Measure (ePROM) intended to refine stroke survivors' self-assessment of their daily activity limitations.

MATERIALS AND METHODS

Cross-cultural adaptation of the EDAQ was completed by a review of expert panel, which included healthcare professionals to increase the clarity and relevancy of the items, followed by cognitive debriefing interviews with British stroke survivors to rate their understanding of the questionnaire items. After developing the paper version of the questionnaire, this was digitised (eEDAQ-SS) and disseminated online via the Stroke Survivors Hub (SSHUB). Content validity of the EDAQ-SS was evaluated using the International Classification of Functioning (ICF) Core Set for Stroke.

RESULTS

The expert panel meeting (n:11) and cognitive debriefing interviews with stroke survivors (n:10) resulted in an EDAQ-SS with 160 items across 15 domains, which was understandable and relevant to stroke survivors. The SSHUB was deemed to be a user-friendly platform, providing easy access to eEDAQ-SS and aid self-assessment of daily activities of stroke survivors. Mapping the EDAQ-SS items to the ICF Core Set for Stroke demonstrated good content validity with 44/55 matching categories.

CONCLUSION

The EDAQ-SS offers a comprehensive measure for self-assessment, which may serve to guide stroke survivors' self-management by overcoming limitations of existing PROMs. Further psychometric testing of the EDAQ-SS and wider testing of the digital version is recommended. CONTRIBUTION OF THE PAPER.

Effects of home-based neurostimulation on outcomes after stroke: a systematic review and meta-analysis

BACKGROUND

Home-based rehabilitation is a cost-effective means of making services available for patients. The aim of this study is to determine the evidence in the literature on the effects of home-based neurostimulation in patients with stroke.

METHOD

We searched PubMED, Embase, Web of Science, Scopus, and CENTRAL for randomized controlled trials on the subject matter using keywords such as stroke, electrical stimulation and transcranial direct current stimulation. Information on participants' characteristics and mean scores on the outcomes of interest were extracted. Risks of bias and methodological quality of the included studies were assessed using Cochrane Risks of bias tool and PEDro scale respectively. The data was analyzed using both narrative and quantitative syntheses. In the quantitative synthesis, meta-analysis was carried out using random effect model analysis.

RESULT

The results showed that, home-based neurostimulation is superior to the control at improving upper limb muscle strength (SMD = 0.72, 95% CI = 0.08 to 1.32, p = 0.03), functional mobility (SMD = -0.39, 95% CI = -0.65 to 0.14, p = 0.003) and walking endurance (SMD = 0.33, 95% CI = 0.08 to 0.59, p = 0.01) post intervention; and upper limb motor function (SMD = 0.9, 95% CI = 0.10 to 1.70, p = 0.03), functional mobility (SMD = -0.30, 95% CI = -0.56 to -0.05, p = 0.02) and walking endurance (SMD = 0.33, 95% CI = 0.08 to 0.59, p = 0.01) at follow-up.

CONCLUSIONS

Home-based neurostimulation can be used to improve upper and lower limb function after stroke.

Sex, gender, and stroke recovery: Functional limitations and inpatient care needs in Canadian and European survivors

BACKGROUND

Stroke is a leading cause of long-term disability among survivors. Past literature already investigated the biological sex differences in stroke outcome; still limited work on gender differences is published. Therefore, the study aimed at investigating whether biological sex and sociocultural gender of survivors play a role as determinants of disability and quality of life among stroke survivors across Europe and Canada.

METHODS

Data were gathered from the European Health Information Survey (EHIS, n = 316,333) and Canadian Community Health Survey (CCHS, n = 127,462) data sets. Main outcomes of interest were disability, assessed through evaluating the impairment of Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (iADL), and inpatient care needs, such as hospitalization or institutionalization. Multivariate logistic regression models were utilized to identify factors independently associated with outcomes. Federated analysis was conducted for cross-country comparisons. Data were adjusted for the country-specific Gender Inequality Index (GII), with higher score corresponding to more gender inequality toward females.

RESULTS

Female survivors showed greater impairments in iADL (odds ratio [OR] = 1.73, 95% confidence interval [CI]:1.53-1.96) and ADL (OR = 1.25, 95% CI: 1.09-1.44), without a corresponding increase in inpatient care needs. Socioeconomic factors such as marital status and income level were significant predictors of disability, with low income and being single/divorced associated with higher risks. The impact of sex was more pronounced in countries with higher GII, indicating the influence of gender inequality on stroke outcomes.

INTERPRETATION

The findings highlight the significant impact of biological sex and gender-related social determinants on post stroke disability, with female sex and unfavorable socioeconomic conditions being associated with worse outcomes.

Impact of Social Support and Self-Efficacy on Activity of Daily Living among Post-Stroke Patients in Saudi Arabia: A Cross-Sectional Study

This study employed a cross-sectional design to explore the impact of social support and self-efficacy on activity of daily living (ADL) among post-stroke patients in Saudi Arabia and investigate the mediating role of self-efficacy. Data were collected from 158 post-stroke patients across six healthcare facilities in three regions of Saudi Arabia using convenience sampling, between February 2023 and July 2023. The analysis included descriptive statistics, variance analysis, and linear regression using bootstrap methods. PROCESS Macro was used for the mediation model. This study revealed that most participants had high ADL, social support, and self-efficacy levels. Significant negative associations were found between ADL and age (p < 0.001), time since stroke (p = 0.009), and stroke history (p < 0.001), while significant positive associations were observed with educational background (p = 0.049), employment status (p < 0.001), and self-efficacy (p < 0.001). ADL in post-stroke patients was significantly influenced negatively by age (p = 0.025), time since stroke (p = 0.027), and stroke history (p < 0.001), while self-efficacy (p < 0.001) had a positive impact and moderated the relationship between social support and ADL. This study highlights the physical and psychosocial aspects affecting post-stroke patients, identifies key areas for enhancing their experiences, and informs the development of targeted interventions to address their comprehensive needs.

Robotic assisted and exoskeleton gait training effect in mental health and fatigue of multiple sclerosis patients. A systematic review and a meta-analysis

PURPOSE

Robotic and Exoskeleton Assisted Gait Training (REAGT) has become the mainstream gait training module. Studies are investigating the psychosocial effects of REAGT mostly as secondary outcomes. Our systematic review and meta-analysis aims to investigate the effects of REAGT in MS patients' mental health and fatigue.

MATERIALS AND METHODS

We searched the electronic databases (Scopus, PubMed, Pedro, Cochrane Trials, Dare) for RCT studies fulfilling our inclusion criteria. A meta-analysis of available assessment tools was conducted calculating the summary mean differences in two different timepoints, before and after the intervention using random-effects models.

RESULTS

The systematic search of the electronic databases identified 302 studies. Seven RCT studies were considered eligible for data extraction and meta-analysis, according to our eligibility criteria. We were able to obtain adequate data to proceed with a quantitative synthesis for QoL SF36-MC (Mental Component), QoL SF-36 mental and psychosocial subscales, Multiple Sclerosis Quality of Life-54-Mental Health Composite (MSQoL-54-MHC), Patient's Health Questionnaire (PHQ-9) and Fatigue Severity Scale (FSS).

CONCLUSIONS

Overall, REAGT seems to have a positive effect to Quality of Life, especially in MS patients' perspective of General and Mental Health and a slight positive effect in depression as measured by PHQ-9.Implications for rehabilitationMultiple Sclerosis (MS) decreases physical and non-physical aspects of patients' quality of life perspective.Rehabilitation strategy must take into consideration the non-physical effects of a training intervention.Robotic and Exoskeleton Gait Training has a positive effect in MS patients' non-physical quality of life and a slight positive effect in depression.

Health-Related Quality of Life of Post-Stroke Patients in a Public Hospital

This study aimed to identify the correlation between influencing factors of activities of daily living (ADLs), mental health, and health-related quality of life (HRQoL) among post-stroke patients who enrolled in a transitional care service in a public hospital. This cross-sectional study involved 67 stroke patients who were enrolled in a transitional care service and visited the outpatient clinic at a public hospital in Seoul between March and December 2022. Their general characteristics, ADLs, mental health, and HRQoL were assessed. The data were analyzed using independent samples t-tests, analysis of variance, and Pearson correlation analysis, and the influencing factors were analyzed using regression analysis. HRQoL showed a statistically significant difference between patients living in different types of arrangements (t = 2.50, p = 0.015), and patients scores on the modified Rankin Scale (t = 7.08, p < 0.001). HRQoL was also significantly correlated with ADLs and mental health in stroke patients (r = -0.59, p < 0.001; r = -0.41, p < 0.001, respectively). Meanwhile, stroke severity (β = -0.30, p = 0.002), living arrangements (β = -0.30, p = 0.009) and ADLs (β = -0.45, p < 0.001) were found to influence HRQoL (F = 6.87, p < 0.001, R2 = 0.47). Reduced dependence for ADLs, improvements in symptoms consequent to stroke, and support related to living arrangements contributed to improved HRQoL and interventions for post-stroke patients in the transitional care service of a public hospital.

Effects of whole-body vibration training on physical function, activities of daily living, and quality of life in patients with stroke: a systematic review and meta-analysis

Purpose: This systematic review and meta-analysis aimed to evaluate the efficacy of whole-body vibration training (WBVT) in patients with stroke, specifically focusing on its effects on physical function, activities of daily living (ADL), and quality of life (QOL). Additionally, potential moderators influencing WBVT outcomes were explored. Methods: We conducted a systematic search of PubMed, Embase, and Cochrane Library from inception to September 2022. Eligible studies were randomized controlled trials employing WBVT in patients with stroke. Two investigators independently extracted the data and calculated the standardized mean difference (SMD) using random-effect models. Results: Twenty-five studies involving 991 patients were included in this meta-analysis. WBVT demonstrated significant reductions in spasticity (SMD = -0.33, 95% CI = -0.61 to -0.06, p = 0.02), improvements in motor function (SMD = 0.39, 95% CI = 0.16 to 0.61, p < 0.01), and enhancements in balance function (SMD = 0.28, 95% CI = 0.09 to 0.47, p < 0.01) in patients with stroke. However, no significant effects were observed for gait (SMD = -0.23, 95% CI = -0.50 to 0.04, p = 0.10), ADL (SMD = -0.01, 95% CI = -0.46 to 0.44, p = 0.97), or QOL (SMD = 0.12, 95% CI = -0.30 to 0.53, p = 0.59). Subgroup analyses revealed that variable frequency vibration and side-alternating vibration exhibited significant efficacy in reducing spasticity and improving motor and balance functions, while fixed frequency vibration and vertical vibration did not yield significant therapeutic benefits in these domains. Conclusion: Our findings indicate that WBVT may serve as a viable adjunct therapy for stroke patients to alleviate spasticity and enhance motor and balance functions. Variable frequency and side-alternating vibration appear to be crucial factors influencing the therapeutic effects of WBVT on these dysfunctions. Nonetheless, WBVT did not show significant effects on gait, ADL, or QOL in stroke patients. Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/, identifier (CRD42022384319).

Efficacy of diaphragmatic breathing exercise on respiratory, cognitive, and motor function outcomes in patients with stroke: a systematic review and meta-analysis

Background

Stroke disrupts the functions carried out by the brain such as the control of movement, sensation, and cognition. Disruption of movement control results in hemiparesis that affects the function of the diaphragm. Impaired function of the diaphragm can in turn affect many outcomes such as respiratory, cognitive, and motor function. The aim of this study is to carry out a systematic review and meta-analysis to determine the efficacy of diaphragmatic breathing exercise on respiratory, cognitive, and motor outcomes after stroke.

Method

The study was registered in PROSPERO (CRD42023422293). PubMED, Embase, Web of Science (WoS), PEDro, Scopus, and CENTRAL databases were searched until September 2023. Only randomized controlled trials comparing diaphragmatic breathing exercise with a control were included. Information on the study authors, time since stroke, mean age, height, weight, sex, and the protocols of the experimental and control interventions including intensity, mean scores on the outcomes such as respiratory, cognitive, and motor functions were extracted. Cochrane risks of bias assessment tool and PEDro scale were used to assess the risks of bias and methodological quality of the studies. Narrative synthesis and meta-analysis were used to summarize the results, which were then presented in tables, risk-of-bias graph, and forest plots. The meta-analysis was carried out on respiratory function [forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow (PEF)] and motor function (trunk impairment, and internal and external oblique muscles activity).

Results

Six studies consisting of 151 participants were included. The results of the meta-analyses showed that diaphragmatic breathing exercise is only superior to the control at improving respiratory function, FVC (MD = 0.90, 95% CI = 0.76 to 1.04, P < 0.00001), FEV1 (MD = 0.32, 95% CI = 0.11 to 0.52, P = 0.002), and PEF (MD = 1.48, 95% CI = 1.15 to 1.81, P < 0.00001).

Conclusion

There is limited evidence suggesting that diaphragmatic breathing exercise may help enhance respiratory function, which may help enhance recovery of function post stroke.

Effects of Virtual Reality Cognitive Training on Neuroplasticity: A Quasi-Randomized Clinical Trial in Patients with Stroke

Cognitive Rehabilitation (CR) is a therapeutic approach designed to improve cognitive functioning after a brain injury, including stroke. Two major categories of techniques, namely traditional and advanced (including virtual reality-VR), are widely used in CR for patients with various neurological disorders. More objective outcome measures are needed to better investigate cognitive recovery after a stroke. In the last ten years, the application of electroencephalography (EEG) as a non-invasive and portable neuroimaging method has been explored to extract the hallmarks of neuroplasticity induced by VR rehabilitation approaches, particularly within the chronic stroke population. The aim of this study is to investigate the neurophysiological effects of CR conducted in a virtual environment using the VRRS device. Thirty patients with moderate-to-severe ischemic stroke in the chronic phase (at least 6 months after the event), with a mean age of 58.13 (±8.33) for the experimental group and 57.33 (±11.06) for the control group, were enrolled. They were divided into two groups: an experimental group and a control group, receiving neurocognitive stimulation using VR and the same amount of conventional neurorehabilitation, respectively. To study neuroplasticity changes after the training, we focused on the power band spectra of theta, alpha, and beta EEG rhythms in both groups. We observed that when VR technology was employed to amplify the effects of treatments on cognitive recovery, significant EEG-related neural improvements were detected in the primary motor circuit in terms of power spectral density and time-frequency domains. Indeed, EEG analysis suggested that VR resulted in a significant increase in both the alpha band power in the occipital areas and the beta band power in the frontal areas, while no significant variations were observed in the theta band power. Our data suggest the potential effectiveness of a VR-based rehabilitation approach in promoting neuroplastic changes even in the chronic phase of ischemic stroke.

A Pilot Feasibility Trial of an Upper Extremity Assistive System

Objective

To develop and clinically evaluate a customizable active upper extremity (UE) assistive system with integrated functional electrical stimulation (FES) that improves function and independence of individuals during activities of daily living (ADLs).

Design

Single-arm, prospective, open-label cohort feasibility trial.

Setting

An academic research institution.

Participants

Subjects were 5 adults with a medical history of stroke resulting in distal UE impairment (N=5). The subjects volunteered from recruitment materials that detailed information about the study.

Interventions

A novel, wearable, lightweight, low-profile, and patient-tailored UE assistive system. It comprises a splint component and FES unit that may each be controlled by electromyography (EMG) signals, inertial measurement units (IMUs), manual control source (joystick), and/or voice control.

Main Outcome Measures

Several occupational therapy outcome measures were used, including the Canadian Occupational Performance Measure (COPM), Action Research Arm Test (ARAT), The Box and Blocks Test (BBT), the ABILHAND-Manual Ability Measure, and Patient Reported Outcomes Measurement Information System (PROMIS) UE Short Form.

Results

All participants learned to use our UE assistive system to perform ADLs and were able to use it independently at home. Most participants experienced a clinically meaningful improvement in both performance and satisfaction for the majority of their COPM goals while using the system. All participants experienced improvement in hand grip and release as shown by their baseline and post assessment scores for hand function (BBT, ARAT) and patient-reported outcomes (ABILHAND, PROMIS).

Conclusions

The clinical outcomes suggest that our UE assistive system improves functional performance in patients with UE impairment, allowing them to engage more actively in ADLs. Further innovation including elbow and shoulder components will allow users to have more degrees of freedom during tasks.

Enhancing early functional independence following cardiac surgery: a quality improvement programme

Early mobility and activity programmes following cardiac surgery are vital for improved patient outcomes, as they accelerate the recovery of functional capacity and walking distance. We observed that only 5.3% of our patients achieved a Functional Independence Measurement (FIM) score of 80% or more by the third postoperative day (POD). Additionally, the average 6-minute walk distance achieved by the fourth POD was only 188 m. Therefore, a quality improvement (QI) project was implemented with the aim of attaining a FIM score of 80% by the third POD for more than 80% of patient underwent/undergoing cardiac surgery without complications.A model-for-improvement framework was used to drive continuous improvement. This project was implemented in February 2021. Baseline data were prospectively collected between November 2020 and January 2021 (preintervention). Outcomes were analysed using standard control chart rules to detect changes over time. Unpaired Student t-tests assessed significant differences in mean levels between two groups, (preintervention vs postintervention).χ2 tests were conducted between the two groups according to gender and patient satisfaction scores.The percentage of patients who achieved a FIM score of 80% or more by the third POD gradually increased to 91.4% 5 months following programme implementation and was sustained thereafter. The mean patient FIM score significantly improved to 81.20±3.77 (p<0.001) by the third POD. Similarly, the mean 6-minute walk distance increased to 267.90±36.10 m (p<0.001) by the fourth POD. The percentage of patients who displayed the level of confidence needed to carry out activities of daily living (ADL) and exercises independently at home increased to 89.4% (p<0.001) by the fifth POD. No adverse events associated with the mobility and activity programme were reported.This QI project demonstrated a substantial improvement in patient functional independence, walking distance and the level of confidence needed to independently carry out ADL and exercises following cardiac surgery.

Predictors of quality of life at 6 months in patients with mild stroke: A prospective observational cohort study

OBJECTIVES

This study aimed to analyze the factors affecting the long-term quality of life of patients with mild stroke and evaluate the differences according to age and sex.

MATERIALS AND METHODS

The Korean Stroke Cohort for functioning and rehabilitation data was used, and patients with mild stroke with a National Institute of Health Stroke Scale score of < 5 were included. Quality of life after 6 months was analyzed using EuroQol-5 dimensions. Demographic and clinical characteristics were evaluated, and factors affecting the quality of life at 6 months were analyzed.

RESULTS

Age, current drinking, marital status, length of stay, and modified Rankin Scale, Fugl-Meyer assessment, Functional Independence Measure, and Geriatric Depression Scale scores affected the quality of life at 6 months in patients with mild stroke. Fugl-Meyer assessment score was a predictor for those aged < 65 years, while the functional ambulatory category was a predictor for those aged ≥ 65 years. Predictors of quality of life, excluding alcohol consumption, were comparable between male and female.

CONCLUSIONS

Among patients aged <65 years, individuals who consumed alcohol, and those who showed better motor function and fewer comorbidities had a higher quality of life. Among patients aged ≥65 years, quality of life was higher in males, younger age, married individuals, those with diabetes, and those with a better walking ability. Among male, individuals who consumed alcohol had a higher quality of life. Rehabilitation treatment should prioritize improving modifiable factors to enhance the quality of life in patients with mild stroke.

Rehabilitation assisted by Space technology-A SAHC approach in immobilized patients-A case of stroke

Introduction: The idea behind the presentation of this case relates to utilizing space technology in earth applications with mutual benefit for both patients confined to bed and astronauts. Deconditioning and the progressiveness of skeletal muscle loss in the absence of adequate gravity stimulus have been of physiological concern. A robust countermeasure to muscle disuse is still a challenge for both immobilized patients and astronauts in long duration space missions. Researchers in the space medicine field concluded that artificial gravity (AG) produced by short-radius centrifugation on a passive movement therapy device, combined with exercise, has been a robust multi-system countermeasure as it re-introduces an acceleration field and gravity load. Methods: A short-arm human centrifuge (SAHC) alone or combined with exercise was evaluated as a novel, artificial gravity device for an effective rehabilitation strategy in the case of a stroke patient with disability. The results reveal valuable information on an individualized rehabilitation strategy against physiological deconditioning. A 73-year-old woman was suddenly unable to speak, follow directions or move her left arm and leg. She could not walk, and self-care tasks required maximal assistance. Her condition was getting worse over the years, also she was receiving conventional rehabilitation treatment. Intermittent short-arm human centrifuge individualized protocols were applied for 5 months, three times a week, 60 treatments in total. Results: It resulted in significant improvement in her gait, decreased atrophy with less spasticity on the left body side, and ability to walk at least 100 m with a cane. Balance and muscle strength were improved significantly. Cardiovascular parameters improved responding to adaptations to aerobic exercise. Electroencephalography (EEG) showed brain reorganization/plasticity evidenced through functional connectivity alterations and activation in the cortical regions, especially of the precentral and postcentral gyrus. Stroke immobility-related disability was also improved. Discussion: These alterations were attributed to the short-arm human centrifuge intervention. This case study provides novel evidence supporting the use of the short-arm human centrifuge as a promising therapeutic strategy in patients with restricted mobility, with application to astronauts with long-term muscle disuse in space.

The Associated Factors of Quality of Life among Stroke Survivors: A Study in Indonesia

Background: The prevalence and burden of stroke are still high, especially in low and middle-income countries. Stroke affects the economy and physics related to the Quality of Life (QoL). Various QoL-associated factors, including sociodemographic, functional outcome, emotional, and cognitive function, were studied. However, there was very limited information about the QoL-associated factors among stroke survivors in Semarang, Indonesia.Purpose: This study aimed to identify the QoL-associated factors among stroke survivors in Semarang, Indonesia.Methods: This cross-sectional study was conducted in outpatient services and involved 57 ischemic stroke survivors using convenience sampling. Demographic and clinical information were obtained using medical records and questionnaires. The questionnaires were the Short Version of Specific Stroke Quality of Life (SS-QoL) to measure QoL, GRID-HAMD 17 to measure Post Stroke Depression (PSD), Mini-Mental Status Examination (MMSE) to measure cognitive impairment, Barthel–Index (BI) to measure functional outcome, Hamilton Anxiety Rating Scale (HAM-A) to measure anxiety, and Multidimensional Scale of Perceived Social Support (MSPSS) to measure social support. Linear regression was conducted in the model performance of QoL-associated factors.Results: The stroke duration was 155(18) days, and 50.9% of participants were males. The linear regression showed that age (-.164 95% CI -.412 - .084), marital status (3.937 95% CI 1.010 - 6.864), functional outcome (.127 95% CI .013 - .241), PSD (-1.090 95% CI -2.144 - -.036), cognitive function (.308 95% CI -.482 - 1.098) and anxiety (-.408 95% CI -1.125 - .268) were QoL-predictors (p<.001, adjusted R2=52.1). It is assumed that age, marital status, functional outcome, PSD, cognition, and anxiety significantly predict the QoL among ischemic stroke survivors.Conclusion: The QoL-associated factors were age, marital status, functional outcome, PSD, cognition, and anxiety. These associated factors of QoL should be considered as elements in formulating nursing interventions that aim to improve the good QoL among stroke survivors.

One-year recurrence of stroke and death in Lebanese survivors of first-ever stroke: Time-to-Event analysis

BACKGROUND

To date, despite the application of secondary prevention worldwide, first-ever stroke survivors remain at imminent risk of stroke recurrence and death in the short and long term. The present study aimed to assess the cumulative risk rates and identify baseline differences and stroke characteristics of Lebanese survivors.

METHODS

A prospective longitudinal study was conducted among survivors ≥18 years old who were followed-up for 15 months through a face-to-face interview. Kaplan-Meier method was used to calculate the cumulative rates of stroke mortality and recurrence. Cox-regression univariate and multivariable analyses were performed to identify the predictors of both outcomes.

RESULTS

Among 150 subjects (mean age 74 ± 12 years; 58.7% men vs. 44.3% women; 95.3% with ischemic stroke vs. 4.3% with intracerebral hemorrhage), high cumulative risk rates of stroke recurrence (25%) and death (21%) were highlighted, especially in the acute phase. Survival rates were lesser in patients with stroke recurrence compared to those without recurrence (Log rank test p < 0.001). Older age was the main predictor for both outcomes (p < 0.02). Large artery atherosclerosis was predominant in patients with stroke recurrence and death compared to small vessel occlusion (p < 0.02). Higher mental component summary scores of quality of life were inversely associated with stroke recurrence (p < 0.01). Lebanese survivors exhibited the highest percentages of depression and anxiety; elevated Hospital Anxiety and Depression Scale (HADS) scores were seen in those with stroke recurrence and those who died (≥80% with mean HADS scores ≥8). Lower Mini-Mental State Examination scores at the acute phase increased the risk of both outcomes by 10% (p < 0.03). Three out of 13 mortalities (23.1%) were presented with early epileptic seizures (p = 0.012). High educational level was the protective factor against stroke recurrence (p = 0.019). Administration of intravenous thrombolysis decreased the risk of both outcomes by 10% (p > 0.05).

CONCLUSION

Higher rates of stroke recurrence and death were observed in the first year following a stroke in Lebanon. Various factors were identified as significant determinants. Thus, health care providers and officials in Lebanon can use these findings to implement effective preventive strategies to best address the management of these factors to reduce the stroke burden and improve the short and long-term prognosis of stroke survivors.

Biomechanical Effects of Adding an Ankle Soft Actuation in a Unilateral Exoskeleton

Stroke disease leads to a partial or complete disability affecting muscle strength and functional mobility. Early rehabilitation sessions might induce neuroplasticity and restore the affected function or structure of the patients. Robotic rehabilitation minimizes the burden on therapists by providing repetitive and regularly monitored therapies. Commercial exoskeletons have been found to assist hip and knee motion. For instance, unilateral exoskeletons have the potential to become an effective training system for patients with hemiparesis. However, these robotic devices leave the ankle joint unassisted, essential in gait for body propulsion and weight-bearing. This article evaluates the effects of the robotic ankle orthosis T-FLEX during cooperative assistance with the AGoRA unilateral lower-limb exoskeleton (hip and knee actuation). This study involves nine subjects, measuring muscle activity and gait parameters such as stance and swing times. The results showed a reduction in muscle activity in the Biceps Femoris of 50%, Lateral Gastrocnemius of 59% and Tibialis Anterior of 35% when adding T-FLEX to the AGoRA unilateral lower-limb exoskeleton. No differences were found in gait parameters. Nevertheless, stability is preserved when comparing the two legs. Future works should focus on evaluating the devices in ground tests in healthy subjects and pathological patients.

Multicomponent Educational-Rehabilitation Approach in Rehabilitation of Patients After Stroke

Rehabilitation must be based on the individual needs and specific goals of the person and must be adapted to his abilities. According to the recommendation of the World Stroke Organization, the team involved in conducting rehabilitation should be multidisciplinary. One of the treatments that are applied within the multidisciplinary approach to a neurological patient is educational-rehabilitation treatment, which is multicomponent in nature. Before starting educational-rehabilitation treatment, an educational-rehabilitation clinical assessment is necessary, which aims to detect difficulties caused by impairment; identify potentials and constraints in these areas; determine the specifics, course, and forecasts of difficulties; formulate clear treatment recommendations; form a watch list that will be available to all team members in the process of diagnosis, treatment, education, and to evaluate the effectiveness of treatment; and continuously monitor the ability and adaptive behavior of the person. Educational-rehabilitation clinical treatment includes treatment of cognitive abilities, treatment of motor skills, relaxation, treatment of adaptive skills, as well as informing the person about the disease and counseling. This review focuses on some aspects of rehabilitation such as treatment of cognitive and motor disorders, treatment of adaptive skills, relaxation issues, and informing and counseling patients from the perspective of an educational rehabilitator with practical experiences in this area of rehabilitation.

'Quality of life at 90 days after stroke and its correlation to activities of daily living': A prospective cohort study

BACKGROUND

The main goal of stroke rehabilitation is to improve the health-related quality of life (HRQoL). In developed countries, several studies evaluating the HRQoL among stroke survivors have been conducted. In India, HRQoL related to stroke as an important health care issue has not received sufficient attention. The study was conducted to encourage the professionals to use stroke-specific HRQoL scales in clinical practice as one of the measures of stroke outcome.

OBJECTIVES

To study the correlation between activities of daily living (ADLs) and HRQoL at 90 days following an acute stroke.

METHODS

In this prospective study, functional independence of patients admitted with stroke were measured using Barthel Index (BI). At 90 days post-stroke patients were assessed using two questionnaires.

RESULTS

Significant improvement in BI total and domains scores at 90 days (p < .001) were seen. At follow-up, Stroke Specific Quality of Life Scale-12 (SS-QoL-12) score for 59 patients was 48 (high QoL). Individuals scored lowest for psychosocial subscale of HRQoL compared to physical subscale. All items and the total score of the BI showed a significant positive partial correlation (p< .001) with the HRQoL total score. The self-care domain of BI showed the highest correlation with QoL total score at 0.88.

CONCLUSIONS

Patient dependent in ADL constantly scored less in all QoL domains. The psychosocial QoL was found to be most affected even in the presence of complete functional independence paving way for further studies on factors that impact psychosocial QoL of stroke survivors.

Effect of a tailored upper extremity strength training intervention combined with direct current stimulation in chronic stroke survivors: A Randomized Controlled Trial

Strengthening exercises are recommended for managing persisting upper limb (UL) weakness following a stroke. Yet, strengthening exercises often lead to variable gains because of their generic nature. For this randomized controlled trial (RCT), we aimed to determine whether tailoring strengthening exercises using a biomarker of corticospinal integrity, as reflected in the amplitude of motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS), could optimize training effects in the affected UL. A secondary aim was to determine whether applying anodal transcranial direct current stimulation (tDCS) could enhance exercise-induced training effects. For this multisite RCT, 90 adults at the chronic stage after stroke (>6 months) were recruited. Before training, participants underwent TMS to detect the presence of MEPs in the affected hand. The MEP amplitude was used to stratify participants into three training groups: (1) low-intensity, MEP <50 μV, (2) moderate-intensity, 50 μV < MEP < 120 μV, and (3) high-intensity, MEP>120 μV. Each group trained at a specific intensity based on the one-repetition maximum (1 RM): low-intensity, 35–50% 1RM; moderate-intensity, 50–65% 1RM; high-intensity, 70–85% 1RM. The strength training targeted the affected UL and was delivered 3X/week for four consecutive weeks. In each training group, participants were randomly assigned to receive either real or sham anodal tDCS (2 mA, 20 min) over the primary motor area of the affected hemisphere. Pre-/post-intervention, participants underwent a clinical evaluation of their UL to evaluate motor impairments (Fugl-Meyer Assessment), manual dexterity (Box and Blocks test) and grip strength. Post-intervention, all groups exhibited similar gains in terms of reduced impairments, improved dexterity, and grip strength, which was confirmed by multivariate and univariate analyses. However, no effect of interaction was found for tDCS or training group, indicating that tDCS had no significant impact on outcomes post-intervention. Collectively, these results indicate that adjusting training intensity based on the size of MEPs in the affected extremity provides a useful approach to optimize responses to strengthening exercises in chronic stroke survivors. Also, the lack of add-on effects of tDCS applied to the lesioned hemisphere on exercise-induced improvements in the affected UL raises questions about the relevance of combining such interventions in stroke.

Uwhangchungsimwon Inhibits Oxygen Glucose Deprivation/Re-Oxygenation-Induced Cell Death through Neuronal VEGF and IGF-1 Receptor Signaling and Synaptic Remodeling in Cortical Neurons

Uwhangchungsimwon (UCW), a multi-component herbal product, has long been used to treat vascular diseases such as headache, dizziness, high blood pressure, and stroke. Though the prophylactic actions of UCW are well known, insufficient experimental evidence exists on its effectiveness against stroke. Here, we investigated the mechanism underlying the efficacy of UCW in oxygen glucose deprivation/re-oxygenation (OGD/R)-injury to the primary cortical neurons using an in vitro ischemia model. Neurons secrete vascular endothelial growth factor (VEGF), which acts as a neurotrophic factor in response to an ischemic injury. VEGF modulates neuroprotection and axonal outgrowth by activating the VEGF receptors and plays a critical role in vascular diseases. In this study, cortical neurons were pretreated with UCW (2, 10, and 50 µg/mL) for 48 h, incubated in oxygen-glucose-deprived conditions for 2 h, and further reoxygenated for 24 h. UCW effectively protected neurons from OGD/R-induced degeneration and cell death. Moreover, the role of UCW in sustaining protection against OGD/R injury is associated with activation of VEGF-VEGFR and insulin-like growth factor 1 receptor expression. Therefore, UCW is a potential herbal supplement for the prevention of hypoxic-ischemic neuronal injury as it may occur after stroke.

Influence of Transcranial Direct Current Stimulation Dosage and Associated Therapy on Motor Recovery Post-stroke: A Systematic Review and Meta-Analysis

Purpose

(1) To determine the impact of transcranial direct current stimulation (tDCS) applied alone or combined with other therapies on the recovery of motor function after stroke and (2) To determine tDCS dosage effect.

Methods

Randomized controlled trials comparing the effects of tDCS with sham, using the Barthel Index (BI), the upper and lower extremity Fugl–Meyer Assessment (FMA), and the Modified Ashworth Scale (MAS), were retrieved from PubMed, Medline (EBSCO), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from their inception to June 2021. Calculations for each assessment were done for the overall effect and associated therapy accounting for the influence of stroke severity or stimulation parameters.

Results

A total of 31 studies involving metrics of the BI, the upper extremity FMA, the lower extremity FMA, and the MAS were included. tDCS combined with other therapies was beneficial when assessed by the BI (mean difference: 6.8; P < 0.01) and these studies typically had participants in the acute stage. tDCS effects on the upper and lower extremity FMA are unclear and differences between the sham and tDCS groups as well as differences in the associated therapy type combined with tDCS potentially influenced the FMA results. tDCS was not effective compared to sham for the MAS. Stimulation types (e.g., anodal vs. cathodal) did not influence these results and dosage parameters were not associated with the obtained effect sizes. Conventional therapy associated with tDCS typically produced greater effect size than assisted therapy. The influence of stroke severity is unclear.

Conclusion

Potential benefits of tDCS can vary depending on assessment tool used, duration of stroke, and associated therapy. Mechanistic studies are needed to understand the potential role of stimulation type and dosage effect after stroke. Future studies should carefully conduct group randomization, control for duration of stroke, and report different motor recovery assessments types.

Quantifying the amount of physical rehabilitation received by individuals living with neurological conditions in the community: a scoping review

Background

Physical rehabilitation is often prescribed immediately following a neurological event or a neurological diagnosis. However, many individuals require physical rehabilitation after hospital discharge. The purpose of this scoping review was to determine the amount of physical rehabilitation that individuals living in the community with neurological conditions receive to understand current global practices and assess gaps in research and service use.

Methods

This scoping review included observational studies that 1) involved adults living with a neurological condition, and 2) quantified the amount of rehabilitation being received in the community or outpatient hospital setting. Only literature published in English was considered. MEDLINE, EMBASE, AMED, CINAHL, Cochrane Library, and PEDro databases were searched from inception. Two independent reviewers screened titles and abstracts, followed by full texts, and data extraction. Mean annual hours of rehabilitation was estimated based on the amount of rehabilitation reported in the included studies.

Results

Overall, 18 studies were included after screen 14,698 articles. The estimated mean annual hours of rehabilitation varied greatly (4.9 to 155.1 h), with individuals with spinal cord injury and stroke receiving the greatest number of hours. Participants typically received more physical therapy than occupational therapy (difference range: 1 to 22 h/year). Lastly, only one study included individuals with progressive neurological conditions, highlighting a research gap.

Discussion

The amount of rehabilitation received by individuals with neurological conditions living in the community varies greatly. With such a wide range of time spent in rehabilitation, it is likely that the amount of rehabilitation being received by most individuals in the community is insufficient to improve function and quality of life. Future work should identify the barriers to accessing rehabilitation resources in the community and how much rehabilitation is needed to observe functional improvements.

Quality of life and physical activities of daily living among stroke survivors; cross-sectional study

Aim

To examine the relationship between quality of life (QoL), level of physical activities of daily living (PADL) and associated factors among stroke survivors during the acute stage as there is little evidence in Sri Lanka.

Design

We conducted a descriptive cross‐sectional study among conveniently recruited stroke survivors in Sri Lanka (n = 134).

Methods

QoL was assessed by the Short Form‐36 (SF‐36), while the PADL was assessed by the Barthel Index (BI). The relationship between SF36 and BI was assessed by Pearson correlation, while Multiple Linear Regression (MLR) was performed to determine the factors associated with QoL and PADL.

Results

The majority of the SF36 domains were below the average level of 50, while BI indicated that most of them belonged to either the severely or totally dependent category. Aphasia, disability, dysarthria, type of stroke, dyslipidaemia, smoking, alcohol consumption, geographical area and income were the associated factors of QoL, while disability of the face and limbs, dysarthria and smoking were the associated factors of PADL (p < .05).

The impact of the COVID-19 pandemic on engagement in activities of daily living in persons with acquired brain injury

PRIMARY OBJECTIVES

This study examined (a) the impact of coronavirus disease-2019 (COVID-19) pandemic on engagement in activity participation in persons with acquired brain injury (ABI); and (b) whether changes in activity participation during the pandemic were associated participants' health-related quality of life (HRQoL).

RESEARCH DESIGN

Exploratory online survey study.

METHODS

Eighty-seven respondents with ABI and 98 healthy adults (HA) participated in this study. Engagement in activity participation during COVID-19 was calculated as a percentage of the activities participants performed before the pandemic.

MAIN RESULTS

Participants with ABI modified their activities less than HA in order to maintain level of engagement in activity participation. They stopped performing more activities during the pandemic compared to HA and compared to their pre-pandemic engagement. Both groups continued to do similar percentage of activities without modifications compared to before the pandemic. Better HRQoL in both groups was predicted by a larger percentage of activities continued and fewer activities stopped.

CONCLUSION

Results emphasize the importance of addressing activity participation changes during situations where there are disruptions of the individual's habits and routines in order to minimize negative consequences of such changes.

Using Machine Learning to develop a short-form measure assessing 5 functions in patients with stroke

OBJECTIVE

This study aimed to develop and validate a machine learning based short measure (the ML-5F) to assess 5 functions (activities of daily living (ADL), balance, upper extremity (UE) and lower extremity (LE) motor function, and mobility) in patients with stroke.

DESIGN

Secondary data from a previous study. A follow-up study assessed patients with stroke using the Barthel Index (BI), Postural Assessment Scale for Stroke (PASS), and Stroke Rehabilitation Assessment of Movement (STREAM) at hospital admission and discharge.

SETTING

A rehabilitation unit in a medical center.

PARTICIPANTS

A total of 307 patients.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The BI, PASS, and STREAM.

RESULTS

A machine learning algorithm, Extreme Gradient Boosting, was used to select 15 items from the BI, PASS, and STREAM, and transformed the raw scores of the selected items into the scores of the ML-5F. The ML-5F demonstrated good concurrent validity (Pearson's r = 0.88-0.98) and responsiveness (standardized response mean = 0.28-1.01).

CONCLUSIONS

The ML-5F comprises only 15 items but demonstrates sufficient concurrent validity and responsiveness to assess ADL, balance, UE and LE functions, and mobility in patients with stroke. The ML-5F shows great potential as an efficient outcome measure in clinical settings.

Effects of telehealth interventions on performing activities of daily living and maintaining balance in stroke survivors: A systematic review and meta-analysis of randomised controlled studies

BACKGROUND

Stroke is one of the most common causes of disability worldwide. In recent years, diverse telehealth programmes for stroke survivors have suggested that this mode of rehabilitation could improve stroke survivors' abilities to perform activities of daily living (ADLs) and maintain balance. Although increasingly utilised in clinical and community settings, the effectiveness of telehealth interventions in stroke survivors remains inconclusive. This warrants investigation so that telehealth interventions are evidence-based and are not merely modalities of convenience.

AIM

To identify the effects of telehealth interventions on the ability to perform ADLs and maintain balance in stroke survivors.

DESIGN

A systematic literature review and meta-analysis were conducted in accordance with PRISMA guidelines.

METHODS

A systematic literature search was performed using seven databases for literature dated up to April 25, 2021. The revised Cochrane risk of bias tool for randomised trials was used to assess the methodological quality of the included studies. A meta-analysis was performed using a random-effects model to calculate the pooled effects of telehealth interventions. Stata 16.0 was used for the statistical analyses.

RESULTS

A total of 14 studies with 1,367 participants were included in the analysis. Overall, telehealth interventions were effective in improving stroke survivors' abilities to carry out their ADLs (standardised mean difference: .45; 95% confidence interval: .12 to .78); however, no significant effects were found on balance.

CONCLUSION

Telehealth interventions are beneficial for improving stroke survivors' performance of their ADLs. Future telehealth intervention trials should focus on identifying essential intervention delivery components that facilitate intervention adoption by clinicians and stroke survivors and sustain the positive effects on stroke survivors' performance of their ADLs in different settings.

RELEVANCE TO CLINICAL PRACTICE

It is essential to build flexibility in the telehealth-based intervention delivery protocol to meet individual stroke survivors' needs to motivate and enhance their ADL performance.

The effect of time spent in rehabilitation on activity limitation and impairment after stroke

BACKGROUND

Stroke affects millions of people every year and is a leading cause of disability, resulting in significant financial cost and reduction in quality of life. Rehabilitation after stroke aims to reduce disability by facilitating recovery of impairment, activity, or participation. One aspect of stroke rehabilitation that may affect outcomes is the amount of time spent in rehabilitation, including minutes provided, frequency (i.e. days per week of rehabilitation), and duration (i.e. time period over which rehabilitation is provided). Effect of time spent in rehabilitation after stroke has been explored extensively in the literature, but findings are inconsistent. Previous systematic reviews with meta-analyses have included studies that differ not only in the amount provided, but also type of rehabilitation.

OBJECTIVES

To assess the effect of 1. more time spent in the same type of rehabilitation on activity measures in people with stroke; 2. difference in total rehabilitation time (in minutes) on recovery of activity in people with stroke; and 3. rehabilitation schedule on activity in terms of: a. average time (minutes) per week undergoing rehabilitation, b. frequency (number of sessions per week) of rehabilitation, and c. total duration of rehabilitation.

SEARCH METHODS

We searched the Cochrane Stroke Group trials register, CENTRAL, MEDLINE, Embase, eight other databases, and five trials registers to June 2021. We searched reference lists of identified studies, contacted key authors, and undertook reference searching using Web of Science Cited Reference Search.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of adults with stroke that compared different amounts of time spent, greater than zero, in rehabilitation (any non-pharmacological, non-surgical intervention aimed to improve activity after stroke). Studies varied only in the amount of time in rehabilitation between experimental and control conditions. Primary outcome was activities of daily living (ADLs); secondary outcomes were activity measures of upper and lower limbs, motor impairment measures of upper and lower limbs, and serious adverse events (SAE)/death.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened studies, extracted data, assessed methodological quality using the Cochrane RoB 2 tool, and assessed certainty of the evidence using GRADE. For continuous outcomes using different scales, we calculated pooled standardised mean difference (SMDs) and 95% confidence intervals (CIs). We expressed dichotomous outcomes as risk ratios (RR) with 95% CIs.

MAIN RESULTS

The quantitative synthesis of this review comprised 21 parallel RCTs, involving analysed data from 1412 participants.  Time in rehabilitation varied between studies. Minutes provided per week were 90 to 1288. Days per week of rehabilitation were three to seven. Duration of rehabilitation was two weeks to six months. Thirteen studies provided upper limb rehabilitation, five general rehabilitation, two mobilisation training, and one lower limb training. Sixteen studies examined participants in the first six months following stroke; the remaining five included participants more than six months poststroke. Comparison of stroke severity or level of impairment was limited due to variations in measurement. The risk of bias assessment suggests there were issues with the methodological quality of the included studies. There were 76 outcome-level risk of bias assessments: 15 low risk, 37 some concerns, and 24 high risk. When comparing groups that spent more time versus less time in rehabilitation immediately after intervention, we found no difference in rehabilitation for ADL outcomes (SMD 0.13, 95% CI -0.02 to 0.28; P = 0.09; I2 = 7%; 14 studies, 864 participants; very low-certainty evidence), activity measures of the upper limb (SMD 0.09, 95% CI -0.11 to 0.29; P = 0.36; I2 = 0%; 12 studies, 426 participants; very low-certainty evidence), and activity measures of the lower limb (SMD 0.25, 95% CI -0.03 to 0.53; P = 0.08; I2 = 48%; 5 studies, 425 participants; very low-certainty evidence). We found an effect in favour of more time in rehabilitation for motor impairment measures of the upper limb (SMD 0.32, 95% CI 0.06 to 0.58; P = 0.01; I2 = 10%; 9 studies, 287 participants; low-certainty evidence) and of the lower limb (SMD 0.71, 95% CI 0.15 to 1.28; P = 0.01; 1 study, 51 participants; very low-certainty evidence). There were no intervention-related SAEs. More time in rehabilitation did not affect the risk of SAEs/death (RR 1.20, 95% CI 0.51 to 2.85; P = 0.68; I2 = 0%; 2 studies, 379 participants; low-certainty evidence), but few studies measured these outcomes. Predefined subgroup analyses comparing studies with a larger difference of total time spent in rehabilitation between intervention groups to studies with a smaller difference found greater improvements for studies with a larger difference. This was statistically significant for ADL outcomes (P = 0.02) and activity measures of the upper limb (P = 0.04), but not for activity measures of the lower limb (P = 0.41) or motor impairment measures of the upper limb (P = 0.06).

AUTHORS' CONCLUSIONS

An increase in time spent in the same type of rehabilitation after stroke results in little to no difference in meaningful activities such as activities of daily living and activities of the upper and lower limb but a small benefit in measures of motor impairment (low- to very low-certainty evidence for all findings). If the increase in time spent in rehabilitation exceeds a threshold, this may lead to improved outcomes. There is currently insufficient evidence to recommend a minimum beneficial daily amount in clinical practice. The findings of this study are limited by a lack of studies with a significant contrast in amount of additional rehabilitation provided between control and intervention groups. Large, well-designed, high-quality RCTs that measure time spent in all rehabilitation activities (not just interventional) and provide a large contrast (minimum of 1000 minutes) in amount of rehabilitation between groups would provide further evidence for effect of time spent in rehabilitation.

Utilization of wearable technology to assess gait and mobility post-stroke: a systematic review

Background

Extremity weakness, fatigue, and postural instability often contribute to mobility deficits in persons after stroke. Wearable technologies are increasingly being utilized to track many health-related parameters across different patient populations. The purpose of this systematic review was to identify how wearable technologies have been used over the past decade to assess gait and mobility in persons with stroke.

Methods

We performed a systematic search of Ovid MEDLINE, CINAHL, and Cochrane databases using select keywords. We identified a total of 354 articles, and 13 met inclusion/exclusion criteria. Included studies were quality assessed and data extracted included participant demographics, type of wearable technology utilized, gait parameters assessed, and reliability and validity metrics.

Results

The majority of studies were performed in either hospital-based or inpatient settings. Accelerometers, activity monitors, and pressure sensors were the most commonly used wearable technologies to assess gait and mobility post-stroke. Among these devices, spatiotemporal parameters of gait that were most widely assessed were gait speed and cadence, and the most common mobility measures included step count and duration of activity. Only 4 studies reported on wearable technology validity and reliability metrics, with mixed results.

Conclusion

The use of various wearable technologies has enabled researchers and clinicians to monitor patients’ activity in a multitude of settings post-stroke. Using data from wearables may provide clinicians with insights into their patients’ lived-experiences and enrich their evaluations and plans of care. However, more studies are needed to examine the impact of stroke on community mobility and to improve the accuracy of these devices for gait and mobility assessments amongst persons with altered gait post-stroke.

Stroke disease-specific quality of life trajectories after rehabilitation discharge and their sociodemographic and clinical associations: A longitudinal, multicentre study

AIM

To investigate the longitudinal growth trajectories of disease-specific quality of life (QoL) dimensions and their associations over 1 year.

DESIGN

A longitudinal design. Data were collected between February 2015-May 2017.

METHODS

Four hundred and fifteen stroke survivors (mean age 70.6 years; 81% ischaemic stroke) were recruited after discharge from rehabilitation hospitals and were followed up every 3 months for 1 year. Changes in Stroke Impact Scale (SIS) dimension scores were evaluated using hierarchical linear models (HLMs) and linear, logarithmic, quadratic, and cubic time slope.

RESULTS

We observed a significant linear and quadratic increase in most SIS dimensions from the baseline to 12-month follow-up, especially in physical dimensions. The communication dimension was stable over time, while the memory dimension increased only linearly. Higher physical dimension scores were significantly associated with lower age, hypercholesterolaemia, and better physical functioning at baseline, while higher communication was associated with lower age, better physical functioning, and a diagnosis of peripheral vascular disease. Better memory was associated with lower age, married status, better physical functioning, and left-hemisphere stroke. Better participation was associated with lower age and better physical functioning. No significant associations were observed for emotion.

CONCLUSIONS

This study provides important information about the trajectories of stroke survivors' specific QoL and their associated variables.

IMPACT

Stroke has a great impact on stroke survivors' QoL. Disease-specific QoL significantly increases from the baseline to 12-month follow-up, especially in physical dimensions. Lower age, hypercholesterolaemia, better physical functioning, and diagnosis of peripheral vascular disease seem to be associated with better QoL. Through the analyses of associated variables, we identified stroke survivors who are more at risk and who need more tailored interventions to improve their physical, psychological, emotional, and social dimensions.

How do the influencing factors of health-related quality of life of the injured patient differ according to activity limitations?

PURPOSE

This study aimed to ascertain the general characteristics of injured patients and use the Andersen Model to identify factors affecting health-related quality of life (QOL) in injured patients with or without activity limitations.

METHODS

We used data of 1602 injured patients from 2014 to 2017 from the population-based Korea National Health and Nutrition Examination Survey, South Korea. QOL was measured using the EQ-5D-3L, and activity limitations were analyzed alongside predisposing factors (gender, age, education level, and marital status), enabling factors (basic living security, health insurance type, private insurance status, household income, and living with family), need factors (number of chronic diseases, subjective health status, and unmet medical needs), and health behaviors (smoking status, alcohol consumption, physical activity, and health screening). Data were analyzed using homogeneity testing, t tests, and logistic and multiple regression.

RESULTS

The mean EQ-5D index was 0.8 with activity limitations and 0.9 without activity limitations. In mobility domain, patients without activity limitations showed significant effects of age, education level, number of chronic diseases, subjective health status, and unmet medical needs on mobility, whereas patients with activity limitations only showed a significant effect of age. In self-care domain, age, household income, and number of chronic diseases showed significant factors on patients without activity limitations, but there was no significant factor associated with activity limitations. Among the factors affecting usual activities, gender was found to have a significant effect only on patients with activity limitations, and subjective health status was found to have a significant effect regardless of activity limitations. Among the factors affecting pain/discomfort, living with family only affected pain/discomfort in patients with activity limitations. Among the factors affecting anxiety/depression, gender and alcohol consumption had significant effects only on patients with activity limitations.

CONCLUSION

Factors affecting the QOL of injured patients differed depending on whether patients had activity limitations. Therefore, when assessing injured patients, it may be necessary to ascertain the extent of activity limitations, and medical institutions and local communities need when implementing education and interventions to improve their QOL.

Game-based movement facilitates acute priming effect in stroke

OBJECTIVE

Cortical priming is an emerging strategy to enhance motor recovery after stroke, however, limited information exists on the neuromodulatory effects of lower limb movement-based priming to facilitate corticomotor excitability after stroke. In this study, we investigated the feasibility and effectiveness of game-based ankle movement priming using the DIG-I-PRIME™ on corticomotor excitability and motor performance in chronic stroke survivors.

METHODS

Nineteen stroke survivors participated in a 20-min session of game-based priming. A period of rest served as a control for the priming condition. Transcranial magnetic stimulation (TMS) was used to measure corticomotor excitability of the paretic and non-paretic tibialis anterior (TA) muscle representations. Motor performance was quantified by assessing the accuracy to track a sinusoidal target wave with paretic dorsiflexion and plantarflexion.

RESULTS

Ipsilesional corticomotor excitability increased by 25% after game-based movement priming (p = 0.02) while changes were not observed after the control condition. No change in motor performance was noted.

CONCLUSION

Game-based ankle movement priming demonstrated a significant acute priming effect on the ipsilesional lower limb M1. These data provide preliminary evidence for the potential benefits of game-based priming to promote functional recovery after stroke.

Comparing static and dynamic emotion recognition tests: Performance of healthy participants

Facial expressions have a communicatory function and the ability to read them is a prerequisite for understanding feelings and thoughts of other individuals. Impairments in recognition of facial emotional expressions are frequently found in patients with neurological conditions (e.g. stroke, traumatic brain injury, frontotemporal dementia). Hence, a standard neuropsychological assessment should include measurement of emotion recognition. However, there is debate regarding which tests are most suitable. The current study evaluates and compares three different emotion recognition tests. 84 healthy participants were included and assessed with three tests, in varying order: a. Ekman 60 Faces Test (FEEST) b. Emotion Recognition Task (ERT) c. Emotion Evaluation Test (EET). The tests differ in type of stimuli from static photographs (FEEST) to more dynamic stimuli in the form of morphed photographs (ERT) to videos (EET). Comparing performances on the three tests, the lowest total scores (67.3% correct answers) were found for the ERT. Significant, but moderate correlations were found between the total scores of the three tests, but nearly all correlations between the same emotions across different tests were not significant. Furthermore, we found cross-over effects of the FEEST and EET to the ERT; participants attained higher total scores on the ERT when another emotion recognition test had been administered beforehand. Moreover, the ERT proved to be sensitive to the effects of age and education. The present findings indicate that despite some overlap, each emotion recognition test measures a unique part of the construct. The ERT seemed to be the most difficult test: performances were lowest and influenced by differences in age and education and it was the only test that showed a learning effect after practice with other tests. This highlights the importance of appropriate norms.

Exploring the factors influencing the use of electrically assisted bikes (e-bikes) by stroke survivors: a mixed methods multiple case study

PURPOSE

E-bikes have the potential to overcome some of the barriers that stroke survivors face with regards to physical activity. This study aims to explore the factors that affect e-bike usage by stroke survivors.

METHODS

A mixed methods multiple case studies design, using semi-structured interviews and GPS data. Subject to GP approval, participants loaned an e-bike or e-trike for up to three months. Interviews were undertaken pre and post intervention. The COM-B behaviour change model acted as a framework for analysis. GPS data relating to journey duration and distance travelled was collected fortnightly.

RESULTS

Six participants were recruited; only three loaned an e-bike/e-trike (with adaptations as required). Storage, being unable to get GP approval, and safety were withdrawal reasons. Level of impairment was a factor influencing the type of e-bike used, level of support required and the motivation of the participants.

CONCLUSION

Stroke survivors can use e-bikes although barriers exist. Electrical assistance was a positive factor in enabling some of the participants to cycle outdoors. Due to the small sample size and the number of participants who were able to loan an e-bike, further research is required to determine whether e-bikes are a feasible and effective intervention to increase physical activity for stroke survivors.IMPLICATIONS FOR REHABILITATIONThe assistance provided by the e-bike/e-trike could provide stroke survivors the opportunity to cycle outdoors.E-bikes/e-trikes could facilitate participation of activities of everyday living such as shopping, hobbies and increase levels of physical activity.Rehabilitation could focus on physical impairment, its effects on self-confidence, and knowledge surrounding the e-bike to overcome barriers to cycling.Social support, the belief that e-bike was an enjoyable mode of physical activity that was good for their health were reported by the participants as important factors for using the e-bike/e-trike.

Impact of post-stroke disability and disability-perception on health-related quality of life of stroke survivors: the moderating effect of disability-severity

OBJECTIVE

The influence of disability-perception on health-related quality of life (HRQoL) remains unclear. This study investigated impact of disability and disability-perception on HRQoL of stroke survivors and explores the moderating effect of disability-severity.

METHODS

Post-stroke disability, disability-perception/acceptance and HRQoL were assessed in 102 stroke survivors using the World Health Organisation Disability Assessment Schedule, Attitudes towards Disabled Persons Form-A and Short Form-36, respectively.

RESULTS

There was significant disability score of at least 42 in the participants with severe disability accounting for 76.5% while 52% of them having positive disability-perception. Although no sex difference exists in their HRQoL, their score was just fair (46.1 ± 1.9) with their physical health being most affected. Severe disability impacted negatively on their HRQoL but disability-perception had no significant effect except in 'role limitation due to the emotional problem' domain. Only severe disability moderated the effects of disability on the overall HRQoL (R ² change = 3.2%; p = 0.018). Disability-severity (mild/moderate and severe disability) moderated the effects of disability level on their physical health (R ² change = 3.1% and 6%; p = 0.012 and 0.0001, respectively).

CONCLUSION

Significant disability exists among stroke survivors and impaired their HRQoL while disability-severity moderating the effect. More stroke survivors have positive attitude towards their disability and impact positively on their physical health.

Alternative Motor Task-Based Pattern Training With a Digital Mirror Therapy System Enhances Sensorimotor Signal Rhythms Post-stroke

Mirror therapy (MT) facilitates motor learning and induces cortical reorganization and motor recovery from stroke. We applied the new digital mirror therapy (DMT) system to compare the cortical activation under the three visual feedback conditions: (1) no mirror visual feedback (NoMVF), (2) bilateral synchronized task-based mirror visual feedback training (BMVF), and (3) reciprocal task-based mirror visual feedback training (RMVF). During DMT, EEG recordings, including time-dependent event-related desynchronization (ERD) signal amplitude in both mu and beta bands, were obtained from the standard C3 (ispilesional hemisphere, IH), C4 (contralesional hemisphere, CH), and Cz scalp sites (supplementary motor area, SMA). The entire ERD curve was separated into three time-phases: P0 (-2 to 0 s), P1 (0 to 2 s), and P2 (2 to 4 s). Four-way and subsequent repeated-measures analyses of variance were used to examine the effects of group (stroke vs. control group), test condition (NoMVF, BMVF, and RMVF), time-phase (P0, P1, and P2), and brain area (IH, CH, SMA) on the ERD areas (%) in mu and beta bands. For the mu band, generally, ERD areas (%) were larger in the control than in the stroke group. The ERD areas (%) were largest under the RMVF condition, followed by BMVF and NoMVF conditions. Similar results were found in the beta bands. The main effects of group, time-phase, and test condition on the ERD areas (%) were significant for the three brain areas, except the main effect of group in the SMA (Cz) and CH (C4) brain area. The ERD areas (%) were larger in the control than in the stroke group. The ERD area (%) was significantly larger during P1 than during P0 and P2 (ps < 0.02), and during P2 than during P0 (ps < 0.01). The ERD area (%) under the RMVF condition was significantly larger than that under the BMVF condition and NoMVF condition (ps < 0.05). The present study suggests that cortical activation particularly in the SMA (Cz) of the brain increases in the RMVF condition in both healthy subjects and stroke patients. This result supports the hypothesis that stroke patients may benefit from RMVF training.

A Pilot Primary Stroke Prevention Program for Elderly Korean Americans

BACKGROUND

Stroke is a significant health issue with devastating consequences among older adults in the United States. However, it can be prevented by improving stroke knowledge and managing risk factors. Many stroke education programs have been shown to be effective. Unfortunately, a minority of older adults, such as older Korean Americans, have not benefited from the programs because of language barriers.

OBJECTIVE

The purpose of this study was to examine the feasibility and preliminary impact of a primary stroke prevention program on stroke knowledge, healthy eating, and physical activity behaviors among Korean Americans.

METHODS

A randomized controlled pilot trial was conducted. A total of 73 persons were randomly assigned to either an intervention group (n = 37) or a control group (n = 36). The intervention program included in-person lectures and discussions. Sociodemographic data were analyzed using descriptive statistics. Analyses of covariance and logistic regression analysis were used to evaluate the effects of the intervention program.

RESULTS

The mean age of participants was 71.49 ± 6.25 years, and most participants were female (74.0%) and married (65.8%). Upon intervention completion, the intervention group showed greater improvements than the control group in stroke knowledge and intake of sodium and total fats (F = 11.89, P = .001, ηp = 0.151; F = 4.04, P = .048, ηp = 0.057; and F = 4.51, P = .037,= ηp = 0.062, respectively). Step counts showed marginal effects (F = 3.27, P = .075, ηp = 0.049).

CONCLUSION

This study demonstrated feasibility and effectiveness of the program to improve stroke knowledge and healthy behaviors in elderly Korean Americans.

Increase in the functional capacity and quality of life among stroke patients by family caregiver empowerment program based on adaptation model

Purpose

The family caregiver's role is an important influence factor of patient's adaptation behaviour and quality of life after stroke. The purpose of this research was to identify the effect of caregiver empowerment program based on the adaptation model (CEP-BAM) on functional capacity and quality of life of patients after stroke.

Methods

This research was a quasi-experimental research with a pre- and post-test control group design. The total participants who completed the research were 80 patients and their families, 40 participants in the intervention group and 40 participants in the control group. We conducted home visits to perform the intervention. The measurement of functional capacity and quality of life performed four times (pre-test and three times post-test). Data analysis was performed using the repeated measurement ANOVA or general linear model repeated measure (GLM-RM).

Results

This research proves a significant difference in functional capacity and quality of life between the two groups and between pre-test and sixth months after intervention (P < 0.05). The quality of life of the intervention group in the sixth month after intervention was better than that of the control group (33.40 ± 3.65 vs 30.60 ± 2.78) with a significant difference (P < 0.05).

Conclusion

It is concluded that CEP-BAM effectively increased patients' functional capacity and quality of life after a stroke in the sixth month after intervention.

A Multidisciplinary Approach to Equipment Use in Pediatric Patient Mobilization

Research has shown that patients who are mechanically ventilated or immobile for greater than 7 days are at increased risk for deconditioning and muscle atrophy. Immobility impacts length of stay as well as patients' ability to return to their prior level of function. As part of the safe patient-handling initiative created at Michigan Medicine, a special team of nurses and therapists was assembled to adapt an adult mobility framework for the pediatric population. The pediatric mobility model determines each patient's specific mobility "phase" based on detailed criteria. Clinical staff can then implement strategies aimed at preventing deconditioning and hospital-acquired weakness. At C.S. Mott Children's Hospital, a multidisciplinary team is available to support this pediatric mobility model. Specific equipment utilized during the different phases of mobility has been reviewed and discussed in this article.

Relation between health utility score and physical activity in community-dwelling ambulatory patients with stroke: a preliminary cross-sectional study

Background The health utility score in patients with stroke relates to physical, psychological, and various other factors. However, the relationship between the health utility score in patients with stroke and objective physical activity has not been clarified. Objective To clarify the relation between the health utility score and objective physical activity in community-dwelling ambulatory patients with stroke. Design A cross-sectional study. Method Patients who received outpatient consultation from a stroke certified nurse after discharge were recruited. We assessed health-related quality of life with the EuroQoL 5-Dimension 3-Level questionnaire and calculated the health utility score. We measured the daily number of steps taken as the index of objective physical activity using an accelerometer. Results Twenty-two patients (72.7% men, 69.5 years old) were included. The health utility score was 0.78 ± 0.14. The physical activity value as indicated by the number of steps taken was 6276.3 ± 4640.7 steps. The health utility score showed a significant positive correlation with the number of steps taken (r = 0.466, p = 0.029). Conclusions The present study showed that the health utility score correlated significantly with objective physical activity in community-dwelling ambulatory patients with stroke. The more the patients with stroke walked, the higher their health utility score was. Further studies should assess other domains of health-related quality of life to comprehensively verify this relationship.

Community mobility after stroke: a systematic review

Background Stroke is the leading cause of severe disability and many survivors report long-term physical or cognitive impairments that may impact their ability to achieve community mobility (CM).

PURPOSE

To determine the extent to which people with chronic stroke achieve CM compared to age-matched norms or non-neurologically impaired controls. Methods The StrokEDGE outcome measures were searched to identify validated tools that included >25% of items addressing CM. MEDLINE, CINAHL, Google Scholar, PubMed, PEDro and the Cochrane databases were searched from 2001 to 2015 with the identified outcome measures cross-referenced against search terms related to stroke and CM.

INCLUSION CRITERIA

utilized a validated CM outcome measure, chronic (>3 months post) stroke survivors, and randomized controlled trial, observational or cohort study design. One reviewer screened the studies and performed data extraction and three performed quality appraisal. Fourteen studies met all inclusion criteria. Results Stroke survivors have impaired CM as demonstrated by 30-83% of normative or non-stroke subject CM scores. As time post-stroke increased, CM improved only slightly. Factors found to correlate with the CM were age, education, general well-being, emotional state, motor function and coordination, independence in activities of daily living, balance, endurance and driving status. Limitations of this review include a relatively high functioning cohort, no meta-analysis and reliance on outcome measures not specifically designed to measure CM. Conclusion Survivors of stroke may experience a significant decrease in CM compared to people without neurological injury. Rehabilitation addressing motor function, coordination, independence in activities of daily living, balance and endurance may be important for achieving higher levels of CM. Outcome measures directly addressing CM are needed.

Effectiveness of exercise in office workers with neck pain: A systematic review and meta-analysis

BACKGROUND

Non-specific neck pain is a common health problem of global concern for office workers. This systematic review ascertained the latest evidence for the effectiveness of therapeutic exercise versus no therapeutic exercise on reducing neck pain and improving quality of life (QoL) in office workers with non-specific neck pain.

METHOD

Seven electronic databases using keywords, that is, 'office workers', 'non-specific neck pain', 'exercise' and/or 'exercise therapy', 'QoL', 'strengthening', 'stretching', 'endurance', 'physiotherapy' and/or 'physical therapy', were searched from inception until March 2017. Heterogeneous data were reported in narrative format and comparable homogenous data were pooled using Revman.

RESULTS

Eight randomised control trials were reviewed and scored on average 6.63/10 on the Physiotherapy Evidence Database (PEDro) scale. Five studies performed strengthening exercise, one study had a strengthening and an endurance exercise group, one study performed stretching exercise and one study had an endurance intervention group and a stretching intervention group. Five and four studies reported significant improvement in neck pain and QoL, respectively, when conducting strengthening exercise. When performing endurance exercises, one and two studies reported significant changes in neck pain and QoL, respectively. The one study incorporating stretching exercise reported significant improvement in neck pain. The meta-analysis revealed that there is a clinically significant difference favouring strengthening exercise over no exercise in pain reduction but not for QoL.

CONCLUSION

There is level II evidence recommending that clinicians include strengthening exercise to improve neck pain and QoL. However, the effect of endurance and stretching exercise needs to be explored further.

Changes in gait and plantar foot loading upon using vibrotactile wearable biofeedback system in patients with stroke

BACKGROUND

Patients with stroke walk with excessive foot inversion at the affected side, which may disturb their balance and gait.

OBJECTIVES

This study aimed to investigate the effects of instant biofeedback of plantar force at the medial and lateral forefoot regions on gait and plantar foot loading in patients with stroke.

METHODS

A total of eight patients with hemiplegic stroke, who had flexible rearfoot varus deformity at the affected side, participated in this study. A vibrotactile biofeedback system was developed and evaluated. It analyzed forces at the medial and lateral forefeet, and instantly provided vibration clues when the plantar force at medial forefoot was less than a threshold. Each subject's three-dimensional gait parameters and plantar-pressure distribution during walking were measured under two experimental conditions (sequence randomized): with and without the device turned on (Trial-registration number: ChiCTR-IPB-15006530 and HKCTR-1853).

RESULTS

Providing biofeedback significantly reduced the foot inversion and increased the mid-stance foot-floor contact area and medial midfoot plantar pressure of the affected limb, bringing the values of these parameters closer to those of the unaffected side. The biofeedback also significantly reduced the unaffected side's excessive knee flexion and hip abduction.

CONCLUSIONS

There were signs of improved foot loading characteristics and gait upon provision of instant vibrotactile biofeedback of plantar force. The positive results of this study further support the development of wearable biofeedback devices for improving gait of patients with stroke.

Impaired Emotion Recognition after Left Hemispheric Stroke: A Case Report and Brief Review of the Literature

Impaired recognition of emotion after stroke can have important implications for social competency, social participation, and consequently quality of life. We describe a case of left hemispheric ischemic stroke with impaired recognition of specifically faces expressing fear. Three months later, the patient's spouse reports that the patient was irritable and slow in communication, which may be caused by the impaired emotion recognition. The case is discussed in relation to the literature concerning emotion recognition and its neural correlates. Our case supports the notion that emotion recognition, including fear recognition, is regulated by a network of interconnected brain regions located in both hemispheres. We conclude that impaired emotion recognition is not uncommon after stroke and can be caused by dysfunction of this emotion-network.

Effects of community-based rehabilitation program on activities of daily living and cognition in elderly chronic stroke survivors

[Purpose] The aim of this study was to examine the effects of community-based rehabilitation program in chronic stroke patients. [Subjects and Methods] Eleven subjects received community-based rehabilitation program ten times for ten months. The main outcome measures were the Modified Barthel Index score for activities of daily living and the Korean Mini-Mental State Examination score for cognition. [Results] The results of the study demonstrated that the community-based rehabilitation program improved activities of daily living performance and cognition significantly. [Conclusion] Based on the study results, the community-based rehabilitation program is an effective method for improving activities of daily living performance and cognitive function in elderly patients with chronic stroke.

Allopurinol and the risk of stroke in older adults receiving medicare

BACKGROUND

Previous studies of allopurinol and stroke risk have provided contradictory findings, ranging from a protective effect to an increased risk. Our objective was to assess whether allopurinol use is associated with the risk of stroke in the elderly.

METHODS

We used the 5 % random sample of Medicare beneficiaries from 2006-2012 to study the association of new allopurinol initiation and incident stroke. We used multivariable-adjusted Cox regression models adjusted for age, gender, race, Charlson index, and cardio-protective medications (beta-blockers, ACE inhibitors, diuretics, statins) to calculate hazards ratio (HR) with 95 % confidence intervals (CI). Sensitivity analyses adjusted for coronary artery disease (CAD) risk factors including hypertension, hyperlipidemia, diabetes, and smoking instead of Charlson index.

RESULTS

Among 28,488 eligible episodes of incident allopurinol, 2,177 ended in incident stroke (7.6 % episodes). In multivariable-adjusted analyses, allopurinol use was associated with 9 % lower hazard ratio for stoke, 0.91 (95 % CI, 0.83 to 0.99). Compared to no allopurinol use, allopurinol use durations of 181 days to 2 years, 0.88 (95 % CI, 0.78 to 0.99) and >2 years, 0.79 (95 % CI, 0.65 to 0.96) were significantly associated with lower multivariable-adjusted hazard of stroke. Sensitivity analyses adjusted for CAD risk factors confirmed these findings. In subgroup analyses, significant associations were noted between allopurinol use and the risk of ischemic stroke, 0.89 (95 % CI, 0.81 to 0.98); associations were not significant for hemorrhagic stroke, 1.01 (95 % CI, 0.79 to 1.29).

CONCLUSIONS

Allopurinol use is associated with lower risk of stroke overall, more specifically ischemic stroke. This association is evident after 6-months of allopurinol use, and the hazard reduction increases with longer duration of use. Future studies need to examine underlying mechanisms.
