초록
본 연구는 만성 뇌졸중 환자 20명을 대상으로 부하자극을 이용한 보행훈련이 만성 뇌졸중 환자의 정적균형 및 동적균형에 미치는 효과를 규명하고자 부하자극보행군 12명과 무부하자극보행군 8명으로 나누어 시행하였다. 부하자극보행군과 무부하자극보행군 모두 동일하게 1회 30분씩 주 5회 일반적 물리치료를 시행하였으며, 부하자극보행군에게 부하자극을 적용한 보행훈련을 1회 20분, 주 3회 실시하였고, 무부하자극보행군에게 부하자극을 적용하지 않은 보행훈련을 1회 20분, 주 3회 실시하였다. 훈련은 6주간 시행되었고 훈련 전ㆍ후에 정적균형과 동적균형을 측정하였으며 다음과 같은 결과를 얻었다. 부하자극보행군은 정적균형은 훈련 전보다 훈련 후에 유의하게 증가하였고(p<.05), 무부하자극보행군은 좌우동요를 제외하고 훈련 전보다 훈련 후에 유의하게 증가하였다(p<.05), 두 군의 전후 변화량의 유의한 차이를 보이지 않았다. 두 군 모두 동적균형은 훈련 전보다 훈련 후에 유의하게 증가하였고(p<.05), 부하자극보행군은 무부하자극보행군에 비해 유의한 증가를 보였다(p<.05). 위의 결과를 바탕으로, 부하자극을 적용한 보행훈련이 만성 뇌졸중 환자의 동적균형능력을 향상시키는 운동방법으로 뇌졸중 환자의 보행 재활에 활용할 수 있을 것으로 생각한다. 또한 정적균형을 향상시키는 방법으로는 적절하지 못하다고 생각한다.
Abstract
The present study examined the effects of gait training with Additional weight in patients with chronic stroke. This study purposed to propose the effectiveness through comparative analysis of the effects of gait training with additional weight and gait training with non-additional weight on static balance and dynamic balance in patients with chronic stroke. The study was conducted at a hospital in Kyoung-ki do and the subjects were divided randomly into two groups: additional weight group(n=12), non-additional weight group(n=8). Both of groups received general physical therapy for 30min in 1 session, 5 sessions per a week during six months. Experimental group practiced gait training with additional weight for 20 min a day, 3 days per a week during 6 months and control group practised gait training with non- additional weight for 20min a day, 3 days per a week during 6 month. Static balance and dynamic balance were tested and analysed before and after the 6 weeks gait training, and the result were as follows. Static balance and dynamic balance is increased significantly in both of groups except for mediolateral sway(p<.05). the result of additioanl weight group showed more significant increase than the result of non-additional weight group (p<.05). According to the result of this study, as gait training with additional weight improves dynamic balance in patients with chronic stroke, this gait training method is effective and suitable for patients with chronic stroke to increase the ability of functional performance.
