Purpose: This study was conducted to identify the effects of dual task training on balance and functional performance in high school soccer players with functional ankle instability. Methods: Twenty high school soccer players with functional ankle instability were randomly assigned to a single task training group and a dual task training group. One participant who did not participate regularly in the training was excluded. The single task training group (n=9) received balance training on an unstable surface. The dual task training group (n=10) received balance training on an unstable surface and had to catch thrown balls during the balance training. Both groups were trained for 4 weeks, 3 days a week. The balance and functional performance of both groups was measured before and after training. Balance was measured using an anterior-posterior and medio-lateral balance. Functional performance was measured based on a figure-of-8 hop test, up-down hop test, and a single hop test. All data were analyzed by repeated two-way ANOVA tests. Results: A time by group interaction effect was not observed in the medio-lateral balance test, figure-of-8 hop test, or single hop test (p>0.05). A time by group interaction effect was observed in the anterior-posterior balance and up-down hop test (p<0.05). Conclusion: These results suggest that dual task training improved balance and functional performance better than single task training for some items.

Balance control deficits have been indicated to be a primary problem among cerebral palsy (CP) patients. Fabric ankle foot orthosis (AFO) can allow more efficient balance control by facilitating proprioception. The purpose of this study was to investigate the immediate effect of fabric AFO on balance, compared to a barefoot condition in children with unilateral CP. Twelve children with unilateral CP participated in this study. Their balance ability was evaluated using pediatric balance scale and bubble test. Both pediatric balance scale and bubble test showed significant improvement with the use of the fabirc AFO (p<.05). The fabric AFO could improve functional balance ability, and promote better balance among children with unilateral CP. We demonstrated that fabric AFO contributed to improving balance among children with unilateral CP, classified as Gross Motor Function Classification System level I and II. Consequently, fabric AFO might be an assistive device leading to the improvement of balance instead of the typical AFOs.

Purpose: This study examined the effects of action-observation training using the Y-Balance on the balance ability of young adults. Methods: Thirty-four healthy adults were randomized into an action-observation group (n=17) or a control group (n=17). All subjects performed the Y-Balance test before and after watching the video. The action observation group watched a video of someone performing a Y-Balance test, and the control group watched a video of scenery unrelated to the training. The subjects were measured through a Y-Balance test for both the length of the legs extended in three directions and the Y-balance composite score. Results: A significant difference in the Y-balance composite score was observed between the two groups. A part of the direction of the extended leg in the action observation group was increased significantly (posteromedial direction of the right leg, posterolateral direction of the right leg, posteromedial direction of left leg) compared to the control group. Conclusion: These results suggest that action observation training only could help improve balance.

Purpose: The study investigated the effect of combined balance exercise using visual feedback and balance pads in rehabilitation of chronic stroke patients. Methods: The participants were 30 patients diagnosed with stroke who met the study selection criteria. Participants were randomly divided into 3 groups of 10: a balance pad exercise (BPE) group, a visual feedback exercise (VFE) group, and a combined balance exercise (CBE) group. All three groups engaged in 30 minutes of exercise, 3 times per week, for 6 weeks. Results: Pre-test and post-test results were analyzed using the functional reach test (FRT), the Berg balance scale (BBS), the timed up & go test (TUG), and the Korean version of the activities-specific balance confidence (K-ABC) scale. The study yielded the following results. Pre- and post-program FRT measures showed significant differences between the BPE and CBE groups (p < 0.05). BBS, TUG, and K-ABC scores showed clear differences in all three groups. Secondly, the CBE group and the BPE group a differed significantly on the BBS before and after the 6-week program (p < 0.05). Finally, the CBE group and the VFE group differed significantly on the BBS before and after the 6-week program (p < 0.05). Conclusion: The study results indicate that combined balance exercise improves balance more effectively than the balance pad and visual feedback exercises. This finding should help to improve rehabilitation in the future.

Objective: This study aimed to evaluate and identify variables for the standing balance of elderly subjects with different balancing abilities by using Kinect and Wii Balance Board. Method: The Berg Balance Scale (BBS) test was performed in 40 elderly subjects aged ${\geq}65years$ who can perform daily activities. The participants were divided into two groups, the healthy seniors (n = 20, BBS score ${\geq}52$) and the seniors with balancing problems (n = 20, BBS score < 52). Each group performed two standing tests (eyes open and eyes close) with two devices (Kinect and Wii Balance Board). The root mean square (RMS), mean distance (MDIST), range of distance (ROD), mean velocity, and 95% ellipse area were calculated from the measured data. Results: Among the calculated variables, RMS, MDIST, and ROD in the mediolateral direction showed significant differences between the two groups and a negative correlation with BBS scores. Conclusion: The results of the present study show that simple standing balance of the elderly can be measured with Kinect and Wii Balance Board, which are low-cost, easy to carry, and easy to use, by using the selected variables.

The purpose of this paper is to examine the effect of the Korean won exchange rates on the Korean service trade balance. Empirical investigation shows that the USD/KRW and JPY/KRW exchange rates have main effects on the Korean service trade balance. Service balance credit and debit(receipts and payments) are negatively related with the USD/KRW and positively related with the JPY/KRW exchange rate. The depreciation of the USD/KRW and JPY/KRW exchange rates leads to the improvement of the service trade balance. Transportation balance is affected by the USD/KRW, JPY/KRW, and CNY/KRW exchange rates, travel balance by the USD/KRW exchange rate, and other business sevice balance by the USD/KRW and JPY/KRW exchange rates.
