  • Purpose : This study was to evaluate the effect of traditional balance training on balance in older adults. Methods : The subjects of this study were thirty elderly over 65 years old. Thirty subjects ranging aged from 66 to 85($74.0{\pm}5.83$) completed the study and participated three times a week for 5weeks. Subjects were assessed by utilizing two different balance measure : Static standing balance was measured by balance performance monitor(BPM). Dynamic balance was measured by timed up and go test(TUG). The scale for static standing balance was measured by using frequence(Hz), sway area($mm^2$), sway path(mm), max sway velocity(mm/s), ant/post sway angle($^{\circ}$), left/right sway angle($^{\circ}$), and sway number. Results : The change in frequency were statistically significant on pre-test and post-test(P<.05), 2. The change in sway area were statistically significant on pre-test and post-test (P<.05), 3. The change in sway path were statistically significant on pre-test and post-test(P<.05), 4. The change in max sway velocity were statistically significant on pre-test and post-test (P<.05), 5. The change in ant/post sway angle were statistically significant on pre-test and post-test (P<.05), 6. The change in left/right sway angle were statistically significant on pre-test and post-test(P<.05), 7. The change in sway number were statistically significant on pre-test and post-test(P<.05), 8. The score on timed up and go test shows statistically significant increase on pre-test and post-test (P<.05). Conclusion : This study suggest that traditional balance training have an effect on balance performance ability for elderly people. Therefore, the traditional balance training is recommended for older adults to improve balance performance ability.

  • Background: Many studies have reported positive results of the various mirror training and virtual reality games in improving dynamic standing balance and posture adjustment in chronic stroke patients. However, no systematic study has been conducted to compare the effects of virtual reality games and the mirror balance training. Objects: The purpose of this study was to compare the effectiveness of Wii balance games and Mirror Self-Balancing Exercises in improving proprioception of knee joint and standing balance of people with chronic stroke. Methods: Twenty patients with chronic stroke volunteered for this study. The subjects were randomly divided into a Wii balance games group and a Mirror Self-Balancing Exercises group with 10 patients in each group. Each training was performed for 30 mins a day for 4 days. In addition to the balance training, 30 mins neuro-developmental-treatment based routine physical therapy was given to both groups. Proprioception was measured using two continuous passive motion devices, and static balance was measured using a Wii balance board. Dynamic balance assessment tools included the Berg Balance Scale, Dynamic Gait Index, and Timed Up-and-Go test. Results: All measured variables before and after the experimental results showed a significant improvement in both groups (p<.05). Only the improvement of the affected knee proprioception appeared to be significantly greater in the Wii balance game group (p<.05). However, other variables did not differ between the groups (p>.05). Conclusion: The findings suggest that both Wii balance games and Mirror Self-Balancing Exercises may be helpful for improving the proprioception of knee joint and the balance of patients with chronic stroke.

  • The purpose of this study was to investigate the complex ankle exercises on balance. 22 participants (male: 14, female: 8) with functional ankle instability were participated. Functional ankle instability was selected to be less than 24 points using the Cumberland ankle instability tool (CAIT) with people who had severe ankle sprain and then experiencing ankle giving way. A total of 20 minutes performed three times a week for four weeks with muscle strength and balance exercises. Muscle strengthening exercise was performed with Theraband, and balance exercise was performed with unstable support plates. Biodex balance system(R) was used to measure static and dynamic balance. The dynamic balance was selected in grade 2, 4, and 8. The static and dynamic balance (grade: 2, 4,and 8) balance was significantly decreased in anterior-posterior, and medial-lateral directions (p<.05). The instability was significantly increased after exercise (p<.05). These results suggest that complex exercises are beneficial to decreasing the functional ankle instability.

  • 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.
