PURPOSE: This study examined the effects of a vestibular stimulation training program on the walking ability of chronic stroke patients over a six month period. METHODS: Forty stroke patients were enrolled in this study. The patients were divided randomly into a control group (n=20) and experimental group (n=20). A general exercise program was applied to Group I and vestibular stimulation training was applied to Group Ⅱ(30 min, three times a week for six weeks). The changes in straight walking ability, curved walking ability, and functional walking ability were measured using a 10 m walking test figure-ofeight-walking test, and dynamic gait index, respectively. The measures before and after the program were compared using a paired t-test for a comparison of each group and an independent t-test for a comparison between groups. RESULTS: The changes in each group were examined †Corresponding Author : Yong-pil Yang

| Abstract |1 )PURPOSE: The purpose of this study was to examine the effects of sciatic nerve mobilization techniques on straight leg raising (SLR) and walking ability in elderly women aged over 65. METHODS:Seventy women aged over 65 were examined using SLR test and forty women were selected as subjects.They were divided into Group Ⅰ (under 70° of SLR test of both legs, n=20) and Group Ⅱ (over 70° of SLR test of both legs, n=20). Nerve mobilization was applied to both groups (three times a week for 4 weeks). SLR angle was measured using digital goniometer and walking ability was measured by step length, stride length, velocity, double support, using GAITRite System. After 4 weeks, paired t-test was used to compare the changes of SLR test and walking ability within †Corresponding Author : seody0815@naver.com This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.GroupⅠ and Group Ⅱ. RESULTS:In Group I, SLR test, step length, stride length and gait velocity were significantly increased but double support was significantly difference. In Group II, SLR test, step length and stride length were significantly increased but gait velocity was not significantly increased and double support was significantly decreased.CONCLUSION: This study showed that sciatic nerve mobilization techniques had positive effects on the SLR angle and walking ability in elderly women.

Based on voluntary participation, 21 obese women in twenties were randomly divided into : Control(no exercise, n=7), GroupⅠ (aerobic exercise 50 minutes, n=7), Group 2 (combined exercise 50 minutes, n=7). All groups conducted allocated program five times a week for six weeks. At post and pre-experiment and at the time of each measurement, changes of body composition and balance among the three groups were statistically analyed using SPSS 18.0 ver. Compared to pre-experiment, Group Ⅰ, Ⅱ showed decrease of weight and body fat rate, but Group Ⅱ showed both increase of muscle mass and decrease of body mass index(p<0.05). In balance ability, Group Ⅱ showed improvement of static and dynamic balance, meanwhile Group Ⅰ showed only improvement of static balance. Therefore, this research showed that combined exercise had positive effects on balance by increasing muscle mass and changing body composition.•
