This study investigated the importance of social cognitive intervention and the cognitive rehabilitation intervention by comparing the difference and examining the relationship between neurological cognitive function and social cognitive function of stroke patients in the acute phase and chronic stroke before returning to the community. LOTCA, cartoon intention inference task, and social behavior sequence task were performed on 30 acute stroke inpatients and 30 chronic stroke patients from May 2015 to June 2016. A two sample t test was conducted to examine the differences between the groups. The Pearson's correlations test was performed to examine the correlation among the variables in each group. As a result, there were statistically significant differences between the neurological cognitive function and social cognitive function of acute stroke patients and chronic stroke patients who were undergoing rehabilitation training before returning to the community (p<0.05). A linear relationship was found between the thinking operation and social behavior sequence task in the acute stroke group (r=0.539, p<0.05). In the chronic stroke group, visual perception (r=0.530, p<0.05), visual motor organization (r=0.655, p<0.05) and thinking operation (r=0.534, p<0.05) were correlated with the cartoon intention inference task. In addition, the social behavior sequence task were correlated with visual organization (r=0.534, p<0.05) and thinking operation (r=0.764, p<0.05). As a result of multiple regression analysis, the neurological cognitive functions influencing the social cognitive function in the cartoon task was found to be the thinking operation (B = 0.431) in acute stroke patients and the thinking operation (B=0.272) and visuomotor organization (B = 0.218) in the case of chronic stroke. In addition, the results of the social behavior sequence task revealed the thinking operation (B=0.417) in the acute stroke patients, and thinking operation (B=0.267), visual motor organization(B=0.274) and visual perception(B=151) in chronic stroke patients to be significant. According to this result, there is a difference in the neurological and social cognitive levels between the two groups. Therefore, the social cognition is strongly related to the high level cognitive function as thinking operation of the neurological cognitive function. Therefore, in further research, it would be necessary to determine if there is a change in higher cognitive function in neurological cognitive function after applying a social cognition intervention program for stroke.

This study aimed to evaluate the effectiveness of imagery training on upper limb function and activities of daily living in subacute stroke patients. This study included 16 voluntary participants with subacute stroke. Subjects were randomly assigned to either experimental or control group, with 8 in each group. Imagery training group performed imagery training during 30 minutes and then task-oriented training 30 minutes a day, 5 times a week for 4 weeks. Control group performed task-oriented training during 30 minutes during a day, 5 times a week for 4 weeks. Assessments were made using the Wolf Motor Function Test (WMFT) and Fugl-Meyer motor function assessment (FMA) to evaluate the changes of upper function. And modified Barthel Index (MBI) was measured to evaluate the activities of daily living. The results showed that imagery training group was more significant increase than control group in WMFT, FMA, and MBI (p<.05). Small to huge effect sizes of 1.59, 2.02, 0.37 were observed for WMFT, FMA, and MBI, respectively. This study indicated that imagery training may be helpful in improving the upper limb function and activities of daily living for subacute stroke patients, and support the clinical feasibility of the imagery training.

Purpose: The aim of this study is to investigate whether motor cortex excitability by transcranial direct current stimulation (tDCS) over primary motor cortex (M1) affects motor performance of serial reaction task. Methods: Cathodal, anodal and sham tDCS (1 mA) are applied over right M1 of 24 subjects for 30 minutes including 11minutes for task period time. We applied two electrodes at the same position to both an experimental group and a sham-controlled group, and we made 2 groups recognize to be applicated of stimulation. Flexion, extension of wrist and thumb flexion are carried out following colors of arrows on the monitor. Serial reaction time task was applied to confirm the difference of the reaction time between 2 groups. Results: Reaction time is decreased in both tDCS-group and Sham-controlled tDCS group, and the degree of reduction is much greater in the post-test than pre-test. Reduction of reaction time between groupsis statistically significant. Conclusion: We consider that anodal tDCS increased the cortical excitability of the underlying motor cortex and it can be helpful to modulate motor performance. It seems that tDCS is an effective modality to modulate brain function, and it will be great help to mediate strategy for the brain injury patients.

Purpose : This study aimed to investigate the effect of trunk postural stability maintained wearing a spiral elastic band on the upper extremity function of patients with stroke who undertook a functional activity program and to provide fundamental data useful for the application of therapeutic interventions in the clinical environment of occupational therapy. Methods : The research subjects included 16 patients with stroke who were evenly divided into an experimental group and a control group. The eight-week intervention consisted of a functional activity program aimed at improving the function of the affected-side upper extremity. The experimental group performed the functional activity program while maintaining a stable trunk posture by wearing a spiral elastic band. The control group followed the program without wearing the band. Upper extremity function was assessed before and after the intervention using a manual function test (MFT) and a motor activity log (MAL), and the effectiveness on the upper extremity function of the affected side was confirmed. Results : First, in the within-group comparison of the upper extremity function scores before and after the intervention, the experimental group showed a statistically significant difference in the MFT and MAL assessment(p<.05). The control group showed a statistically significant difference in the MAL assessment(p<.05). Second, in the between-group comparison of the change in scores after the intervention, a statistically significant difference was observed between the two groups in all assessments(p<.05). Conclusion : This study confirmed the positive effect on upper extremity function of trunk stabilization posture using a spiral elastic band. The results could be useful when implementing a task-oriented training program in the clinical environment of occupational therapy in the future, as application of the training while maintaining trunk postural stability by wearing a spiral elastic band could be more effective for improving the upper extremity function of patients with stroke.

Objective : The purpose of this study was to investigate the effects of bimanual intensive training on Upper Extremity Function and activities of daily living in stroke patients. Methods : The subjects were 18 patients who were diagnosed with hemiplegic stroke. They were randomly assigned to bimanual intensive training group (n=9) and unilateral intensive group (n=9). Bimanual training group performed bimanual task and unilateral training group performed one hand task for 1 hour per session, 5 times a week, for 4 weeks. Chi-square test, Wilcoxon signed rank test, and Mann-Whitney U test were used for analysis. Results : The results showed that, upper extremity motor function and bimanual coordination were significantly improved in patients in the bimanual training group (p<.05). Additionally, the ratio of affected hand use and amount of use/quality of movement in the hemiplegic upper extremity in activities of daily living for patients in the bimanual training group were significantly improved (p<.05). Although the unilateral group improved motor upper extremity function and activities of daily living in the upper extremity (p<.05), it was not significantly different from that in the bimanual training group. In between-group comparison, bimanual coordination and ratio of the affected hand use in a day were significantly different (p<.05). Conclusion : It is reasonable to conclude that bimanual intensive training therapy is an effective intervention method to improve upper extremity motor function, and activities of daily living in stroke patients.

Background: Motor imagery is the mental representation of an action without overt movement or muscle activation. However, few previous studies have demonstrated motor imagery training effects as an objective assessment tool in patients with early stroke. Objective: To investigate the effect of motor imagery training on Somatosensory Evoked Potentials (SSEP) and upper limb function of stroke patients. Design: A quasi-experimental study. Methods: Twenty-four patients with stroke were enrolled in this study. All subjects were assigned to the experimental or control group. All participants received traditional occupational therapy for 30 minutes, 5 times a week. The experimental group performed an additional task of motor imagery training (MIT) 20 minutes per day, 5 days a week, for 4 weeks. Both groups were assessed using the SSEP amplitude, Fugl-Meyer assessment of upper extremity (FMA UE) and Wolf motor function test. Results: After the intervention, the experimental group showed significant improvement in SSEP amplitude and FMA UE than did the control group. Conclusion: These findings suggest that the MIT effectively improve the SSEP and upper limb function of stroke patients.

Purpose: The purpose of study was to measure stroke patients' ability to balance and their degrees of clinical function and to examine the effect of the aquatic exercise method using tasks related to these features. Methods: Twenty stroke patients were randomly assigned to an aquatic task exercise group and a land task exercise group. Both groups used the same exercise method for 60 minutes each session, three times a week for 12 weeks at the same time point and with the same amount of exercise. Results: Before and after the exercise, static balance was measured using balance measuring instruments locomotive faculties, muscular strength, and dynamic balance were assessed through the Berg balance and 10 m gait tests. Finally, gait abilities were measured, and the data obtained were analyzed to generate the results. Conclusion: Both groups showed significant improvement, but the aquatic exercise group showed slightly more significant results in static balance, Berg balance, and upright walking tests. It is thought that the improvement of stroke patients' balance and gait ability can be triggered through the application of aquatic exercise programs in the future.

Objectives : Previous studies reported that attention-deficit hyperactivity disorder (ADHD) resulted from a deficit of selective attention and sustained attention. In this study, we assessed the result of methylphenidate-induced changes of the cerebral frontal executive functions in patients with ADHD. Methods : The subjects in this study consisted of 16 ADHD patients whose age ranged from 7 to 12. We used ADHD Diagnostic System (ADS) for the attention improvement, and the Stroop Test for the executive function response to pharmacotherapy with MPH. Results : After pharmacotherapy with methylphenidate for 12 weeks, the study group showed improvement in the clinical aspects through Clinical Global Impression-Severity, ADHD-rating scale and Inattention/Overactivity With Aggression Conner's Parents Rating Scale. In the ADS test, only in auditory task there was a decrease of both the response time and the standard deviation of the response time significantly. In the Stroop Test, there was a decrease in the word task, color task and color-word task significantly. Conclusion : Our results show that psychostimulant medication improves neuropsychological function, including the cerebral frontal executive function. This study implies that we have to consider the improvement of executive function, as well as attention when evaluating the efficacy of treatment.
