Abstract

The purpose of this study was to investigate the effect of dual task training on postural stability and balance in chronic stroke patients. A total of 25 ambulatory hemiplegic stroke patients were recruited into this study and randomly assigned into two groups, the dual task training group (n=13) and control group (n=12). Both groups received general physical therapy for 30 minutes a day, 5 days a week during 6 weeks. In addition, dual task training group received dual task training programs for 50 minutes a day, 3 days a week during 6 weeks. The scores of Trunk Impairment Scale (TIS), Postural Assessment Scale for Stroke (PASS) and postural sway with eye opened and eye closed on the Force Plate were assessed before and after intervention. Postural stability and balance significantly improved after training in the dual task training group(p<0.05). The result suggests that dual task training is feasible and suitable for individual with chronic stroke.

본 연구는 이중과제 훈련이 만성 뇌졸중 환자의 자세안정성과 균형능력에 미치는 효과를 알아보고자 하였다. 실험을 위해 모집 된 이동 가능한 25명의 편마비 환자를 무작위화 하여 이중과제 훈련군 13명과 대조군 12명으로 나누었다. 두 그룹 모두 6주간 주 5회 일 30분의 일반적인 물리치료를 시행하였으며, 추가적으로 이중과제 훈련군은 6주간 주3회 일 50분의 이중과제 훈련을 실시하였다. 훈련 전후 체간손상척도, 자세조절능력과 눈을 뜨고 감은 상태에서의 자세동요를 측정하였다. 연구 결과 이중과제 훈련군에서 자세안정성과 균형능력이 유의하게 향상되는 것을 확인할 수 있었다(p<0.05). 본 연구의 결과를 통하여 이중과제 훈련이 만성뇌졸중 환자에게 효과적인 운동방법이 될 수 있을 것이라 생각한다.
