뇌졸중 편마비 환자의 12주간 수중재활운동 프로그램에 따른 지면반력의 변화

Abstract

The purpose of this study was to analyze ground reaction force(GRF) when hemiplegia patients walk after 12 weeks task-oriented aqua-rehabilitation program. Seven male hemiplegia patients who can walk without stick were participated in this study, and they exercised three times a week for 12 weeks. The GRF was analyzed to examine effects of aqua-rehabilitation program. The paired sample t-test conducted to verify statistical differences between pre and post test(p<0.05). The results were as follow ; Gait time was decreased from 2.32±0.63sec to 1.63±0.36sec (p<0.05). In case of sound side, step time was decreased from 1.37±0.43sec to 0.95±0.31sec, and in case of involved side, step time was decreased from 0.95±0.24sec to 0.68±0.10sec (p<0.05). The percentile time that to reach maximum vertical GRF was decreased from 33.03±14.62%time to 18.25±10.85%time in sound side (p<0.05). The percentile time that changed from braking phase to propulsive phase was decreased from 47.49±9.27%time to 26.25±6.76%time in involved side (p<0.05). The maximum propulsive force in antero-posterior direction was increased from 0.12±0.02BW to 0.16±0.02BW in sound side (p<0.05). The antero-posterior shift range of center of pressure was increased from 13.64±5.22cm to 20.27±3.34cm (p<0.05). On balance, task-oriented aqua-rehabilitation program for hemiplegia patients might have good effects to develop balance ability and to increase gait speed.
