초록
본 연구의 목적은 만성 뇌졸중 환자를 대상으로 전동식 보행 훈련이 보행과 이동성 및 동적 균형 능력에 어떠한 효과를 주는지 알아보고자 하였다. 연구에 참여한 대상자 21명 중 전동식 보행 훈련군(11명)은 일반적인 재활치료에 부가적으로 전동식 보행 훈련 시스템을 이용하여 주 3회, 20분씩 8주간 보행 훈련을 시행하였고 대조군은 일반적인 재활치료를 시행하였다. 보행 변수 측정은 GAITRite, 이동성은 일어나 걸어가기 검사, 동적 균형 능력은 버그 균형 척도를 이용하였다. 집단 내와 집단 간 비교를 위하여 대응표본 t-검정과 독립표본 t-검정을 각각 시행하였다. 본 연구 결과 전동식 보행 훈련군은 대조군보다 일어나 걸어가기 검사(p<.001)와 버그 균형 척도(p<.05)에서 더 유의한 향상을 보였다. 보행 변수에서 전동식 보행 훈련군이 대조군보다 보행 속도(p<.05)와 마비ㆍ비마비측 유각기(p<.05), 마비측 입각기(p<.05), 비마비측 보장(p<.001), 유각ㆍ입각(p<.01), 보장 대칭성(p<.001)에서 유의한 차이가 있었으나 분속수와 비마비측 입각기 및 마비측 보장에서는 유의한 차이가 없었다. 따라서 전동식 보행 훈련은 뇌졸중 환자의 비대칭적인 보행 패턴을 개선하는데 더 효과적인 훈련방법으로 제시 할 수 있을 것이다.
Abstract
This study was to investigate the effect of gait, mobility and balance ability through conventional rehabilitation therapy(CRT, n=10), gait training using an electromechanical gait trainer with(GT, n=11) in chronic stroke patients. All groups received conventional PT gait training based on the rehabilitation therapy (5 times×a week(30 min)/8 weeks). GT group got the gait-trainer session(3 times×a week(20 min)/8 weeks). To find out the effect, inspected the Gait spatio -temporal variable, symmetry index, We used Timed Up and Go Test(TUG), Berg Balance Scale(BBS) and obtained results as follows. The GT group was more effective than CRT group to improve functional gait ability and dynamic balance measured by TUG(p<.001) and BBS(p<.05). The GT group was statistically significant difference as compared with the CRT group in the gait velocity, swing phase of affected & non-affected side(p<.05), standing phase of affected side(p<.05), step length(p<.001), swing & standing phase(p<.01) and symmetrical index of step length of non-affected side(p<.001). However, there wasn’t significant difference in cadence, standing phase non-affected side and step length of affected side. In conclusion, this study suggests that Electromechanical Gait Trainer will be able to offer hemiparetic stroke patients the possibility of effective gait training to be changed asymmetrical gait pattern.
