만성 뇌졸중 환자의 Sit to stand 훈련 시 발의 위치에 따른 균형과 보행의 변화

Change of balance and gait parameters while sit to stand with different foot position in chronic stroke patient

Objective: The purpose of this study is to investigate the effect of balance and gait parameters while sit to stand training with different foot position in chronic stroke patient. Method: 26 patients with chronic stroke were enrolled in rehabilitation hospital in Hwaseong. Subjects were divided into two groups. Control group were maintain symmetrical foot position while sit to stand training. Experimental group were maintain asymmetrical foot position while sit to stand training induce more activity increase in paretic lower limb. We checked COP length, COP average velocity through balance parameters. And steplength, stridelength, stance phase, cadence, gait velocity were checked by gait parameters. Zebris walking analysis system used as an experimental tool. Results: COP length and COP average velocity were significant difference in both groups which pre and post evaluation(p<.01). Also steplength, stridelength, stancephase were significant difference in both groups which pre and post evaluation(p<.01). But both groups were no significant difference in cadence and gait velocity. COP length and COP average velocity, steplength, stance phase change were significant difference between two groups(p<.01). Stridelength also show significant difference(p<.05). However, there was no significant difference in cadence and gait velocity between two groups. Conclusion: Sit to stand training with induce more activity toward paratic limb may improve balance and gait parameters in patients with chronic stroke.
