The objective of this study was to effect of Tai Chi on balance and muscle activity of ankle joints with USN sensor in elderly people. Thirty six elderly participated and randomly assigned to a experimental group with Tai Chi and control group. The experimental group trained using a Tai Chi through 3 times per a week over 6 weeks. For all subjects, their balance such as functional reach test and one leg stance test, the change of muscle activity of ankle joints with USN sensor wireless-electromyogram during leg closed stance with eye closed were measured, and the results were as followed. The results were of a signigicant changes to the balance in group and between group as well. Comparison of muscle activity left tibialis anterior and left gastrocnemius in group, there were significant difference. Comparison of muscle activity right tibialis anterior and right gastrocnemius in group, there were significant difference. Comparison of muscle activity between groups, there was significant difference. Additional results indicated that, elderly people who received Tai Chi in one study, improve balance control and muscle activity ankle joint. so it is anticipated that improvement in clinical utilization for the elderly who's gait ability and balance ability reduced.

연구목적: 닌텐도 위를 이용한 가상현실기반 비디오게임 프로그램을 만성기 뇌졸중 환자에게 적용하여 균형능력 및 일상생활동작에 어떠한 영향을 미치는지 알아보고, 뇌졸중 환자의 재활프로그램으로서 적용 가능성이 있는지 알아보고자 한다. 연구방법: 만성기 뇌졸중 환자를 무작위로 가상현실기반 비디오게임 프로그램을 적용한 실험군(n=7)과 적용하지 않은 대조군(n=10)으로 구분하여 연구를 진행하였다. 연구에 참여한 모든 대상자에게 30분의 Bobath therapy와 15분간의 FES 치료를 기본적으로 실시하였다. 이에 더하여 실험군은 가상현실기반 비디오게임 프로그램을 1일 30분이내, 주 5회, 3주간 실시하였다. 대조군은 자전거 운동과 보행훈련으로 30분간 시행하였다. 실험 전 후 눈뜨고 외발서기(OLST; open leg standing test), Timed Up and Go(TUG) 검사, 10m 걷기 검사, Functional Independence Measure(FIM)를 측정하였다. 실험 전과 실험 후 측정값의 차이를 비교하기 위해 Wilcoxon Signed Ranks Test를 실시하였다. 그리고 각 측정값의 변화량에 대한 실험군과 대조군 사이의 차이를 알아보기 위해 Mann-Whitney U Test를 실시하였다. 연구결과: 실험결과는 다음과 같다. 1) 실험군에서는 FIM의 유의한 증가와 TUG, 10m 걷기 검사의 유의한 감소를(p<.05) 보였다. 대조군에서는 OLST의 증가와 TUG, 10m walking test의 감소가 나타났지만 통계적으로 유의하지 않았다. 오직 FIM에서만 유의한 증가가 나타났다(p<.05). 2) 실험 전 후의 실험군과 대조군의 각 측정값들의 평균차를 비교한 결과 실험군은 대조군보다 실험 전 후 OLST, TUG, 10m walking test 차이의 평균은 컸지만 통계적으로 유의하지 않았다. 결론: 이상의 결과로부터 가상현실기반 비디오게임이 만성기 뇌졸중 환자의 동적균형능력 및 일상생활동작 향상에 효과가 있음을 알 수 있었다.

The purpose of this study was to investigate the effects of 12weeks complexed lower body muscle-strengthening exercise program on fall risk in elderly women. Twenty subjects volunteered to participate who use a welfare center in W city For the study we divided into two groups: exercise group (EC, n=10, mean age:$69.6{\pm}2.2$), comparative group(CG, n=10, mean age:$71.3{\pm}4.6$). In order to investigate the effect of lower body muscle-strengthening program on the degree of risk of fall. It reached a conclusion as follows after having applied BBS (Berg Balance Scale) and OLST (One-Leg Stance Test) to examine the degree of risk of fall. As a result of changes in BBS and OLST, there were significant differences between EG and CG for each test(p<.00). Therefore, it confirmed that the application of complexed lower body muscle-strengthening program to the elderly who have a high risk of fall influences the risk of fall positively.

This study was conducted to investigate the effects of a participatory rehabilitation program on sit-rise and rise-to-walk test performances, and perception and motor skills in adults with medically vulnerable individuals and, adults with developmental disabilities in particular. Seventeen adults with developmental disabilities participated in a participatory rehabilitation program using resistance bands and exercise balls, for 60 minutes once weekly over 13 weeks. Their performances were measured before and immediately after the intervention, and 12 weeks after. The findings were as follows. In the sit-rise test, the number of times rising from sitting posture increased after the intervention versus before, but the difference was not statistically significant. In the rise-to-walk test, the performance showed statistically significant difference over time, and the post-hoc test showed a significant effect after the intervention versus before. There was no significant difference in perception and motor skills. In sum, the participatory rehabilitation program positively influenced dynamic balancing related to functional activities but had no significant effect on perception and motor skills, which is related to motor control and motor learning. It is suggested that to increase the participation in community activities, reduce fall risk, and improve dynamic balancing abilities in adults with developmental disabilities, participatory rehabilitation programs should be utilized to promote the physical wellbeing.

This study aimed to examine the evolution of exercise performance and medical assessments in U-12 youth football players. Participants were recruited from an youth football players (YFG, n=15; $11.2{\pm}0.9yrs$) and normal youth (CON, n=15; $11.5{\pm}0.6yrs$). Both groups were tested for exercise performance (health related physical fitness, skill related physical fitness, functional movement screen; FMS and Y-balance) and medical assessments (lower extremity alignment, range of motion; ROM and manual muscle test; MMT). YFG showed a positive effects on pacer in health related physical fitness, 50-m run and Single-leg standing with eyes closed in skill related physical fitness, active straight leg raise and rotary stability in FMS, non-dominant composite score in Y-balance, respectively compared to CON. However, YFG showed a negative effects on Q-angle of dominant and non-dominant in lower extremity alignment, dorsiflexion of non-dominant, plantarflexion of dominant and non-dominan in ROM, hip extension and abduction, knee flexion and extension of dominant, knee flexion and extension of non-dominant in MMT, respectively compared to CON. These results indicated that U-12 youth football players have shown excellent exercise performance, but medical assessments has proved negative effects.
