Abstract.[Purpose] The purpose of this study was to evaluate the effects of dual-task balance training on stroke patients' balance performance. [Subjects and Method] Forty stroke patients were allocated equally and randomly to an experimental group and a control group. The experimental group performed the dual-task balance training of standing on a balance pad and moving a cup containing water. The control group performed the single-task balance training of maintaining balance on a balance pad. All the subjects exercised five times per week for 4 weeks. Each group's balance performance (sway area, sway path, and maximum velocity) was measured using a balance performance monitor, both prior to and after the exercise program.[Results] Comparing measurements from before and after the exercise program, both the experimental group and the control group showed statistically significant changes in sway area and maximum velocity, but not for sway path. Comparing the two groups, the experimental group showed more significant changes than the control group in sway area and maximum velocity, but there were no significant differences in sway distance between the two groups.[Conclusion] For the stroke patients, Dual-task balance training was more effective than single-task balance training. The results should help to promote the wider clinical application of dual-task balance training programs for stroke patients.

The purpose of this study is to examine the effect of dynamic stabilization exercise on unstable surface on thickness, muscle density and white area index (WAI) of transverse abdominis muscle and multifidus muscle. The subjects were 20s healthy adults and 27 people were measured for muscle thickness and muscle density, white area index after the experiment conducted during a six-week dynamic stabilization exercises divided into three groups, each in a different plane. The results showed a significant difference between the three groups (p <.05). Repeated measures analysis of variance (repeated ANOVA) results, transverse abdominis muscle and multifidus muscle thickness showed a significant difference between the groups in the time difference (p <.05), and between multifidus muscle density and white area index in the comparison between groups showed a significant difference (p <.05). In conclusion, showed significant difference in lumbar stabilization exercise part. These results seems to be utilized as a basis for future research on the lumbar stabilization exercise.

The purpose of this study is to examine the effects of types of shoes and distance travelled on oxygen saturation and walk in relation to smoking. Methods: To achieve this goal, the researcher divided 20 normal male adults into two groups: a smoking group (10) and a non-smoking group (10) and used a treadmill to have them walk in intervals of 3 days, a total of 4 times. Results: By analyzing their walk, the following results were obtained: oxygen saturation showed statistically significant results in both the smoking group and the non-smoking group. The smoking group showed significant results for left pace and significant results were achieved for setting foot and shaking in both the smoking group and the non-smoking group. In comparison of oxygen saturation between groups, there were significant results for 3km sneakers walk and 3 km slippers walk. There were significant results for width in 3 km sneakers walk, left and right pace in 3 km slippers walk, and setting foot in 1 km sneakers walk. Conclusion: In conclusion, in the smoking group changes in walk occur if the shoes are more unstable and the distance travelled becomes longer.
