지적·청각장애인의 12주간의 근력, 평형성, 보행훈련이 보행형태에 미치는 영향

초록

The purpose of this study was to investigate the effects of Muscle Strength, Balance and Gait Training on Gait Pattern development in Mentally handicapped and Hearing-Impaired People. The subjects of this study consisted of 2 participants mentally handicapped and 1 Hearing-Impaired participants who participated in the Muscle Strength, Balance and Gait Training on Gait Pattern for 12 weeks, 3 times a week. To achieve the purpose of the research of Gait Kinematic Variables were measured using treadmill, video recording equipment, video analysis equipment as experimental tools and analytical equipment. The results obtained from the above research procedures were as follows:In terms of time-related variables, it was found that all participants here of showed gradual increment in the specific time period of left and right foot stance, where as time period of swing phase decreased. In terms of distance factors, changes in steps length, stride width lower limb length were examined. In factor related to lower limb length, the height of the CM positions in the Gait Cycle of all the subjects’ from RHC 1 to RTO2 were found to be increased after the training than before. In terms of joint angle, ankle joint angle, knee joint angle and toe out angle were examined. The ankle joint and knee joint angle from the phase of RHC1, LTO1, LHC, RTO of all the subjects decreased after the training. Moreover, the toe out angle of the right foot increased than the previous research. In terms of velocity variables, on the whole gait velocity was found to be slower than the previous researches. However, gait velocity increased after the training than before.
