초록

본 연구는 만성 뇌졸중 편마비 장애인을 대상으로 과제 지향적 기능운동을 적용하여 운동 전—후에 근력, 균형 및 보행능력의 변화를 비교하는데 목적이 있다. 독립보행이 가능한 10명을 선정하여 주당 3회씩 6주간 운동 프로그램을 진행하였다. 운동은 앉기-서기, 팔뻗기, 물건집어 옮기기, 다양한 환경에서 걷기 등이 포함되었다. 평가는 도수근력계를 이용하여 하지 근력을 검사하였고 힘판을 이용한 정적균형능력, TUG, BBS를 측정하여 동적균형능력을 알아보았다. 또한 10m 보행시간을 측정하여 보행능력을 평가하였다. 운동 전·후 차이를 검증하기 위하여 대응표본 t 검정을 실시하였고 모든 통계적 유의수준은 .05로 하였다. 연구결과 운동 프로그램 후 고관절 굴곡근(p<.05), 슬관절 신전근(p<.05)의 근력이 유의하게 증가하였고, 총동요거리의 유의한 감소(p<.05)와 TUG의 유의한 감소 (p<.05), BBS의 유의한 증가(p<.05)로 균형능력의 향상을 보였으며, 10m 보행시간이 유의하게 감소(p<.05)하여 보행능력의 향상이 나타났다. 고관절 굴곡근력은 균형, 보행능력과 유의한 상관관계를 보였으며(p<.05), 동적균형능력은 보행능력과 유의한 양적 상관관계를 나타냈다(p<.05). 본 연구의 결과에 따라 과제지향적 기능운동이 만성 뇌졸중 편마비 장애인의 근력과 균형 및 보행능력에 효과가 있음이 나타났다. 앞으로 균형과 보행능력 향상을 위한 재활훈련계획에 유용한 자료로 이용될 것으로 기대한다.

Abstract

The purpose of this study was to investigate the effect of task-oriented functional training on a muscle strength, balance and gait ability of chronic stroke patients. Ten patients who were able to walk independently were evaluated in this study. Subjects exercised three times a week for 6 weeks. Functional Exercises consist of sit to stand, reaching, pick up, transfer and gait on various environments. We measured strength of lower extremity by manual muscle tester, static balance by forceplate, dynamic balance through TUG and BBS. 10m walking time reflects gait ability. The paired t-test was performed to analyze differences between pre- and post- tests and α=.05 set up with the significant level. The major findings of this study were that task-oriented functional exercises brought about increases in strengths of knee extensor(p<.05) and ankle dorsiflexor(p<.05), decrease in a average sway path(p<.05), decrease in TUG(p<.05), increase in BBS(p<.05) and decrease in a 10m walking time(p<.05). The strength of knee extensor to be significantly correlated with balance, gait ability(p<.05). Dynamic balance has positive correlation with gait ability(p<.05). We suggest that task-oriented functional training enabled stroke patient to improve the muscle strength, balance and gait ability, which is contribute to plan to rehabilitation exercise.
