초록
본 연구는 만성 뇌졸중 환자에게 앉은 자세에서의 이중운동과제 훈련을 통하여 앉은 자세에서의 균형 능력을 알아보고자 하였다. 연구의 대상은 만성 뇌졸중 환자로 하였으며 무작위 배정을 통하여 이중운동과제 훈련군 14명과 대조군 14명으로 나누었다. 두 군 모두 동일하게 6주 동안 주 5회, 1회 60분간의 일반적인 운동치료를 적용하였으며, 이중운동과제 훈련군에게는 추가로 6주 동안 주 3회, 1회 30분간의 이중운동과제를 기초한 훈련을 적용하였다. 훈련 후 힘판을 이용한 자세동요속도를 통해 3가지 조건(눈뜬 상태, 눈감은 상태, 불안정한 지지면 상태)에서 균형 능력을 평가하였다. 이중운동과제 훈련의 결과로 앉은 자세에서 좌우동요속도와 총동요속도가 유의하게 감소되었다(p<.05). 위의 결과를 통하여 앉은 자세에서의 이중운동과제 훈련이 만성 뇌졸중 환자의 앉은 자세에서의 균형 능력 향상에 도움이 되며 신체 기능을 향상시키는데 효과적인 운동 방법이 될 수 있을 것으로 사료된다.
Abstract
This study was to investigate the effect of sitting balance ability through dual motor task training on sitting position in chronic stroke patients. Twenty-eight subjects after twelve month post stroke were participated. The subjects were randomly divided into two groups: an dual motor task training group (n=14) and a control group (n=14). Both groups received conventional rehabilitation program for five session sixty minutes per week during six weeks. Dual motor task training group practiced additional dual motor task training programs on thirty minutes a day, three days a week during six weeks. Main outcome measures were right/left, anterior/posterior, and total sway velocity on sitting position using forceplate with three conditions(eye opened, eye closed, and foam). Tests performed six weeks before and after the experimental treatment program. The results of study represented that the dual motor task training group showed significant improvement in sitting balance (right/left and total sway velocity) (p<.05). In conclusion, dual motor task training combined with a conventional rehabilitation program improves sitting balance. These results suggest that dual motor task training is feasible and beneficial for individuals with a chronic stroke.
