Purpose: The purpose of this study was to obtain detailed and quantified data concerning the effects of plantarflexor muscle fatigue induced in the non-paretic side on the spatial and temporal gait parameters of the bilateral lower extremities during walking in stroke patients. Methods: This study was conducted on 20 patients with chronic stroke. The load contraction fatigue test was applied to induce muscle fatigue in the non-paretic plantarflexor muscle. Step length, stride length, double support, gait velocity and cadence, and functional ambulatory profile (FAP) score in the bilateral lower extremities were measured using a gait analysis system in order to investigate changes in temporal and spatial gait parameters caused by muscle fatigue on the non-paretic side. The statistical significance of the results was evaluated using a paired t-test. Results: A review of the results for gait parameters revealed a significant increase in double support (p<0.05) and a significant decrease in step length, stride length, gait velocity and cadence, and FAP score (p<0.05). Conclusion: These results indicate that the muscle fatigue in the non-paretic side of the stroke patients also affected the paretic side, which led to a decrease in gait functions. This implies a necessity to perform exercise or training programs in a range of clinical aspects not causing muscle fatigue.

Objectives The purpose of this study was to examine comparison of tension according to the type of sling cord during the bridging exercise with sling in stroke patients. Methods Twenty six stroke patients were recruited for this study. Subjects were randomly performed sling bridging exercise with three types of sling cords such as nonelastic cord with affected side-nonelastic cord with non affected side (NC-NC), nonelastic cord with affected side-elastic cord with non affected side (NC-EC), and elastic cord with affected side-nonelastic cord with non affected side (EC-NC). They were measured tension with a tensiometer of sling cord during the bridging exercise with sling. Results The tension of sling cord was significantly different in affected side, non affected side, and tension ratio of affected side/non affected side. There were significant differences tension in NC-EC from NC-NC and EC-NC and the NC-EC method was increased tension of affected side and decreased tension of non affected side. Conclusions These results showed that the NC-EC method was improved the symmetry of affected side and non affected side. Sling exercise with appropriate type of sling cord should be increased activities of affected side and improved recovery in stroke patients.

Purpose: The purpose of this study was to investigate the effect of temporary visual block existence and nonexistence on the change in foot pressure and foot area in stroke patients. Methods: Sixty-one chronic stroke patients volunteered to participate in the study. Foot pressure and foot area were measured using the Biorescue system. The subject maintain a comfortable standing position on the pressure-measuring plate one meter away from the computer. The sequence of the visual variation data while standing on the measuring plate was collected randomly. The data were collected with three repetitions and used the five-second measuring values except the first second and the last second according to each visual condition. All data were analyzed using SPSS version 21.0. The significance level for the statistical inspection was set as 0.05. Results: The comparison between the visual existence and nonexistence status showed statistically significant effects on foot pressure and foot area. The visual nonexistence status showed more improvement in foot pressure symmetry and area than visual existence status. Conclusion: This study shows that the foot pressure and foot area for the chronic stroke patients changed according to the visual states. It is predicted that these data will be used in rehabilitation training programs and to present temporary changes in visual status for stroke patients.

Purpose : The purpose of this study was to evaluate the criterion-related validity of the Berg balance test between fallers and non-fallers in individuals with Parkinson's disease. Methods : Thirty-one patients were recruited for this study. Their initial diagnosis had been made on average $30.1{\pm}10.1$ years earlier. Score of Berg balance test showed significant correlations with indicators of motor functioning and daily living capacity. Berg balance test score was inversely associated with the unified Parkinson's disease rating scale-motor score, and Schwab and England activities of daily living rating scale. Results : In all 3 correlations, lower scores on the Berg balance test correlated with higher unified Parkinson's disease rating scale-motor scores. Results support the criterion-related validity of the Berg balance test. Conclusion : Our research results agree with other published research in suggesting that the Berg balance test may be used as a screening tool and ongoing assessment tool for patients with Parkinson's disease.

Purpose: The purpose of the study was to identify the effects of proprioceptive neuromuscular facilitation (PNF) training and robot rehabilitation training on trunk stability and standing balance in individuals with chronic stroke. Methods: There were 30 patients with chronic stroke, divided into two groups: 15 subjects who received PNF and robot training (the experimental group) and 15 subjects who received standard conservative training (the control group), that participated. The experimental group received treatment for 60 min: 30 min of conventional physical therapy, 15 min of PNF training, and 15 min of robot training. The control group received conventional physical therapy for 60 min. Trunk stabilization (trunk impairment scale) and standing balance (center of pressure, limit of stability, modified functional reach test, and Berg balance scale) were measured before and after intervention. Results: Within each group, both the experimental and control groups significantly improved after the intervention in all tests; however, the experimental group showed greater improvement in scores on the trunk impairment scale, the center of pressure, the limit of stability, the modified functional reach test, and the Berg balance scale. Conclusion: The study verified that PNF training and robot training had a positive influence on trunk stability and standing balance indices in patients with chronic stroke.

Purpose: This study aims to verify the effectiveness of sit-to-stand training with visual feedback to improve balance ability and knee extensor strength of total knee replacement patients. Methods: In this study, 15 patients with total knee replacement participated in this study. Subjects were assigned to two groups: a feedback group (experimental group)(n = 8) and a control group (n = 7). They all received 30 min of continuous passive motion (CPM) and sit-to-stand training for 15 min five times per week for two weeks. Knee extensor and balance ability were measured. Knee extensor was measured by Biodex system 3; balance ability was measured by Balancia software. Results: After the intervention, there was a significant difference in the strengthening of the knee extensor muscles in the feedback group, area 95%, weight distribution of the affected side, and the sit-to-stand test repeated five times (p < 0.05). Conclusion: The results of this study showed that sit-to-stand training with visual feedback was more effective in increasing knee extensor muscle strength and balance ability than the sit-to-stand training without visual feedback. Therefore, in order to improve the knee extensor muscle and the balance of total knee replacement patients, it is necessary to consider providing visual feedback during sit-to-stand training.
