The purpose of the study was to determine the effects of balance training with 'TETRAX' system, a balance training and assessment tool, on balance and mobility in acute hemiplegic patients. Nineteen matched subjects were assigned randomly into either an experimental group or a control group. An experimental group with 10 subjects received balance training with 'TETRAX' exercise program and conventional physical therapy interventions 5 times per week during 4 weeks. A control group with 9 subjects received conventional physical therapy interventions 5 times per week during 4 weeks. Outcome measures were taken before and after 4 weeks of interventions using the Stroke Rehabilitation Assessment of Movement (STREAM), the Berg Balance Scale (BBS), gait speed, and the fall down index. Results indicated that both exercise groups improved significantly in STREAM, BBS, and gait speed (p<.05). The experimental group had a little improvement than the control group. Both exercise groups did not show statistical significance in fall down index (p<.05). Following 4 weeks of intervention, except gait speed there was no statistically significant difference between two groups. However, these findings suggest that conventional physical therapy interventions with visual feedback training could be effective on improving balance and mobility than conventional physical therapy alone in acute hemiplegic patients.

Purpose: The purpose of this study was to examine the effect of weight-bearing training with an elastic band during functional electrical stimulation (FES) on walking and balance functions in stroke patients. Methods: Twenty patients with chronic stroke were divided into an experimental group assigned to weight-bearing training with an elastic band during functional electrical stimulation (FES; n=10) and a control group assigned to weight-bearing training alone during FES (n=10). The patients in both groups attended physical therapy sessions five times a week for four consecutive weeks. The experimental group underwent weight-bearing training with an elastic band during FES five times a week for four weeks. The control group underwent weight-bearing training during FES. Balance parameters were measured before and after the intervention using the Balancia program. Moreover, all patients were evaluated using the Berg Balance Scale (BBS), the Time Up and Go Test (TUGT), and the Wisconsin Gait Scale (WGS) before and after each intervention. Results: The results showed that weight-bearing training with elastic bands during FES and weight-bearing training during FES had a significant effect on the affected side's weight-bearing ratio, BBS, TUGT, and WGS in both groups (p <0.05). Additionally, the results showed that the changes observed in the two groups indicate significant differences in path length, average speed, BBS score, TUGT time, and WGS score between the groups (p < 0.05). Conclusion: In patients with stroke, weight-bearing training with an elastic band during FES affected on walking and balance. Therefore, it is an optional intervention for the balance and walking ability of stroke patients.

Purpose: The purpose of this study was to examine the impact of gluteus medius (GM) strengthening training using the pressure biofeedback unit for lower extremity muscle function and balance ability in stroke patients. Methods: Twenty-seven stroke patients (14 men, 13 women) volunteered to participate in this study. They were randomly assigned to 3 groups: pressure biofeedback unit GM training, general GM training, and control group. Experimental group 1 performed GM strengthening training using PBU in the sidelying position. Experimental group 2 performed GM strengthening training without PBU in the sidelying position. The training program lasted 4 weeks (20-minute sessions, three times a week). Muscle function was assessed by measuring muscle strength and endurance, and Berg balance scale (BBS), Lateral Reach Test (LRT), and limited of stability (LOS) velocity were measured for evaluation of balance ability. Results: Enhancement of muscle strength and endurance was significantly higher in experimental group 1 than in the other two groups (p<0.05). In comparison of the balance function, experimental group 1 showed a significantly enhanced ability to balance (p<0.05). After the intervention, experimental group 1 showed a significant reduction of LOS velocity in the anterior direction and affected direction (p<0.05). There was no significant difference than the other two groups but a large reduction was observed. Conclusion: These findings suggest that selective gluteus medius strengthening training using the pressure biofeedback unit is effective for lower extremity muscle function and balance ability in stroke patients.

Therefore, the purpose of this study was to investigate the effects of an 8-week pilates core-muscle training on balance ability and asymmetry index of the L-sit on the rings in male elite gymnasts. Method: Ten elite gymnasts (age: $20.6{\pm}0.7years$, height: $169.9{\pm}4.9cm$, weight: $65.4{\pm}5.6kg$, career duration: $20.6{\pm}0.7years$), who are students at K-university, participated in this study. Results: First, the range of the COM tended to decrease in the anterior-posterior direction. Second, the left hip joint angle and knee extension and ankle dorsiflexion angles significantly increased after the pilates training. Third, the ROM also increased. Fourth, the symmetry value increased in the hip angle, while the symmetry index in all joints of the ROM decreased. As a result, the pilates core-muscle training influenced the static balance ability during the L-sit on the rings. Conclusion: Accordingly, the pilates core-muscle training is suitable in enhancing the basic balance ability in gymnastics on rings.
