Abstract

This study is to investigate the effect of lower extremity strength exercise using biofeedback system on community-based elderly. Ten community-based elderly were exercised using the biofeedback system (with functional electrical stimulation) three times a week for six weeks. Data analysis was performed using Wilcoxon signed rank test. Physical function improved significantly, but there was no significant difference in muscle strength and muscle mass. Although elderly people were able to confirm that community-based ICT home biofeedback training could be possible and could lead to improvements in the lower extremity function, further research is needed to demonstrate a clearer effect by expanding the target population, distinguishing the sexes, and providing a personalized training method.

본 연구는 바이오피드백 시스템을 활용한 하지 근력 강화 운동이 지역사회기반 노인에게 어떠한 영향이 있는지 알아본 연구이다. 지역사회기반 노인 10명을 대상으로 주 3회, 6주 동안 바이오피드백 시스템(기능적 전기 자극 동반)을 활용하여 운동을 실시하였다. 데이터 분석은 Wilcoxon signed rank test를 사용하였다. 본 연구 결과 신체 기능은 유의하게 좋아졌으나 근력 및 근육량에서는 유의한 차이가 없었다. 노인들도 지역사회기반 ICT 활용 가정 바이오피드백 훈련이 가능하며, 하지 기능 개선을 유도할 수 있음을 확인할 수 있었지만, 대상자수 확대, 성별 구분, 개인 맞춤형 훈련 방식 제공 등으로 보다 명확한 효과를 입증할 수 있도록 추가적인 연구가 필요하다.
