This study was carried out to find out the basic data required to plan and develop Rehabilitation Day Care Program for the stroke survivor's family in Korea. The subjects comprised of 92 stroke survivor's family who discharged from 4 hospitals in Seoul during the past 2 years. The data were collected from August 3, 1998 to September 18, 1998, through interviews with questionnaires about general characteristics, activities of daily living, depression and service need of rehabilitation day care program at the outpatient clinics by trained nursing graduates. Data were analyzed with descriptive analysis, Pearson's correlation analysis, and Stepwise multiple linear regression analysis using SPSS/WIN 10.0 program. The results obtained are as follows; 1. The mean score of the general need of rehabilitation day care program of stroke survivor's family was 3.10(range 1-4). The highest need among the service categories of the rehabilitation day card program was self-care and restorative activities category(3.30), and health services referral category, recreation category, psychosocial activities category in order. The needs of each category are as follows. In the health services referral category, the need for dental examination and medical examination were highest, followed by the need for physical therapy and occupational therapy. In the psychosocial activities category, the need for family counselling was highest. In the self-care and restorative activities category, the need for ROM exercise training was highest, followed by bowel training, and ambulation training. 2. The need of family for rehabilitation day care program service displayed a correlation with the level of education, ADL, and the level of depression, and a reverse correlation with age, illness intrusiveness, depression, knowledge, subject and object burden and relationship with stroke survivors. 3. The stepwise multiple linear regression analysis revealed following results. For the need for rehabilitation day care program service, 22.6% of the variance was initially explained by level of family's knowledge about caring method for stroke survivors, 8.8% was the level of subjective burden and 5.4% was relationship with stroke survivors. In conclusion, above characteristics should be considered to develop stroke survivors' rehabilitation day care program.

In this study, we aimed to determine which medical conditions of the stroke patients admitted for rehabilitation more than four weeks after onset affect caregiver burden. Participants diagnosed with stroke and their respective primary caregivers were enrolled and assessed after an 8-week follow-up period. The areas of evaluation for stroke patients included neurologic state, cognition, performance in daily life movements, gait, and balance, and caregivers were evaluated in the area of burden. The evaluation was conducted at the start of the rehabilitation course and eight weeks later. Patient caregivers were found to be under mild to moderate burden while providing care throughout the hospitalization period. The patient's neurologic state and cognition were correlated with caregiver burden. In the all patient and the subacute stroke patient group, multiple regression analysis confirmed that the neurologic state and balance stability were factors that influenced caregiver burden. Hence, we suggest that improvement in the patient's balance stability be emphasized during the course of rehabilitation to mitigate caregiver burden.

Objectives: To compare the effects of Eastern-Western integrative medical care (EWIM) and Western single rehabilitation therapy (WSRT) on the functional recovery of stroke patients.Methods: Seventy-six stroke patients were recruited retrospectively. The participants were divided into two groups: EWIM and WSRT. Data on age, sex, stroke-related risk factors, stroke type, neurological deficits according to the National Institutes of Health Stroke Scale (NIHSS), elapsed time to the initiation of rehabilitation, duration from the onset to follow up, initial functional status, and function after therapy for 3 mon were obtained from a review of the patients’ medical records. Between-group differences in functional outcomes were analyzed before and after treatment using the functional ambulation category (FAC), Fugl-Meyer assessment (FMA), modified Barthel Index-Korean version (K-MBI), and Euro-Quality of Life-5 Dimension (EQ-5D).Results: At 3-mon poststroke, all the functional outcome measures had improved in both groups (P<0.05). However, the improvements were greater in the EWIM group, and the improvement was statistically significant in the K-MBI (P=0.048) and EQ-5D (P=0.042).Conclusions: With respect to activities of daily living and health-related quality of life, EWIM is a more effective stroke therapy than WSRT.

Purpose: The aim of this study was to evaluate functional gait and pulmonary function of patients with subacute or chronic stroke for aperiod after the onset of stroke. Healthy people of similar ages served as a control group. The study focused on the clinical importance of intervention with cardiopulmonary rehabilitation treatment in patients with stroke. Methods: The standard time period used to differentiate the subacute and the chronic stroke groups was six months. Each group, including the control, was allocated 11 subjects. Vital capacity (VC), forced vital capacity (FVC), and forced expiratory volume at one second ($FEV_1$) were measured with a spirometer for each subject. Walk tests (10 m and 6 min) and functional gait tests were then conducted. Results: Significant differences were noted for VC, FVC, and $FEV_1$ between the subacute stroke group and the normal group and between the chronic stroke group and the normal group (p<0.05), but no significant difference was evident between the subacute stroke group and the chronic stroke group (p>0.05). No significant difference was seen between the subacute stroke group and the chronic stroke group in the 6min walk test (p>0.05), whereas a significant difference was observed between the subacute stroke group and the chronic stroke group in the 10 m walk test (p<0.05). Conclusion: The general rehabilitation treatment is effective with respect to functional aspects, but it has limited effect in improving pulmonary function and muscular endurance. Therefore, additional intervention of cardiopulmonary rehabilitation is necessary in the rehabilitation treatment process of patients with stroke.

Purpose : The purpose of this randomized controlled trial study was to examine the effect of transcranial direct current stimulation (tDCS) on cognitive function and depression in stroke patients. Methods : Thirty stroke patients were randomly divided into an experimental group (n = 15) and a control group (n = 15). The experimental group received tDCS while performing computerized cognitive rehabilitation programs, and the control group was provided with sham tDCS while operating the same programs. The 30-minute intervention was implemented five times per week for six weeks. To assess cognitive function before and after the intervention, the Neurobehavioral Cognitive Status Examination was conducted; the Beck Depression Inventory BDI was employed to assess depression. Results : The experimental group showed statistically significant increases in cognitive function and decreases in depression (p < .05 ). Comparing the amount of variation between the groups after arbitration also showed significant differences in cognitive function and depression between the two groups (p > .05). Conclusion : The application of tDCS and computerized cognitive rehabilitation programs for stroke patients may positively affect their cognitive function and depression. Therefore, tDCS used with computerized cognitive rehabilitation programs is positively applicable to the enhancement of cognitive function in stroke patients and reduction of depression.

Objective: Stroke is a leading cause of disability worldwide, often leaving survivors with significant cognitive and motor impairments. Dual-task (DT), which involves performing cognitive and motor tasks simultaneously, can influence brain activation patterns and functional recovery in stroke patients. Design: A systematic review Methods: Following PRISMA guidelines, databases including MEDLINE, CINAHL, Embase, and Web of Science were searched for studies assessing cortical activation via functional near-infrared spectroscopy (fNIRS) during DT performance in stroke patients. Studies were selected based on predefined eligibility criteria, focusing on changes in hemodynamic responses and their correlation with task performance. Results: Eight studies met the inclusion criteria. Findings indicate that DT leads to increased activation in the prefrontal cortex (PFC), premotor cortex (PMC), and posterior parietal cortex (PPC), suggesting an integrated cortical response to managing concurrent cognitive and motor demands. However, increased activation did not consistently translate to improved functional outcomes, highlighting the complex relationship between brain activation and rehabilitation success. Conclusions: DT interventions may enhance cortical activation and neuroplasticity in post-stroke patients, but the relationship between increased brain activity and functional recovery remains complex and requires further investigation. Tailored DT programs that consider individual neurophysiological and functional capacities are recommended to optimize rehabilitation outcomes.

Background: Stroke recovery is a long and complex process. Successful stroke recovery seems to be strongly associated with patients' high motivation and committed participation. Patients' motivation is a key determinant of successful rehabilitation outcomes, but it is difficult in defining and measuring. Patients' participation is defined as the degree or extent to which subjects take part in rehabilitation activities and can be measured by observable behavior. Objects: The purpose of this study was to investigate the impact of patients' level of participation in rehabilitation on functional outcomes in patients with stroke. Methods: Forty post-stroke inpatients participated in this study. The level of rehabilitation participation was measured by the Hopkins Rehabilitation Engagement Rating Scale (HRERS). Other measures used for the evaluation were the Rivermead Mobility Index (RMI) and Korean version of the Modified Barthel Index (K-MBI). Overall measurements were made at early intervention and late intervention. Spearman correlation and multiple regression were used to measure the relationships between HRERS, RMI, and K-MBI. Results: The correlation found between HRERS total scores at early intervention and RMI total scores of late intervention was above moderate (r = 0.607, p < 0.01). RMI total scores at early intervention (p < 0.000), HRERS total scores at early intervention (p < 0.001), and disease duration (p < 0.003) were significant predictors of RMI total scores at late intervention. Conclusion: The level of participation at early intervention was associated with improvement in mobility. The level of mobility at early intervention, disease duration, and patients' participation at early intervention were important determinants of functional outcome. These findings suggest that patients' participation should be encouraged in order to achieve successful stroke recovery.

Recent advances in computer science enabled people with severe motor disabilities to use brain-computer interfaces (BCI) for communication, control, and even to restore their motor disabilities. This paper reviews the most recent works of BCI in stroke rehabilitation with a focus on methodology that reported on data collected from stroke patients and clinical studies that reported on the motor improvements of stroke patients. Both types of studies are important as the former advances the technology of BCI for stroke, and the latter demonstrates the clinical efficacy of BCI in stroke. Finally some challenges are discussed.
