The purpose of this study was to determine the test-retest reliability and the concurrent validity between tinetti mobility test (TMT), berg balance scale (BBS) and space balance 3D which is one of the computerized measurement and visual feedback balance assessment system in subacute stroke patients. Twenty three ambulatory acute stroke subjects were measured the TMT, BBS and space balance 3D. The test-retest reliability(intra-class correlation coefficient: ICC) indicated that the static and dynamic balance in space balance 3D considered moderate reliability and TMT, BBS were good reliability. In case of concurrent validity, there were moderate validity (p<.01) between static balance test with space balance 3D and each TMT, BBS. But there were only poor validity (p<.05) between center to forward-left, center to backward-left phase in dynamic balance test with space balance 3D and each TMT, BBS. These findings suggest that in subacute stroke patients the test-retest reliability and concurrent validity using the space balance 3D and TMT were valuable in balance test but there was limitation to evaluate dynamic balance test.

본 연구는 아급성 뇌졸중 환자를 대상으로 컴퓨터화된 시각적 되먹임 균형 훈련 및 평가 장비인 space balance 3D와 기능적 검사인 tinetti mobility test (TMT)의 신뢰도 및 버그균형척도와의 동시타당도를 분석하기 위해 실시하였다. 아급성 뇌졸중 환자 총 23명을 대상으로 하였고 대상자에게 space balance 3D, TMT, 버그균형척도를 이용해 균형 능력 평가를 실시하였다. 검사-재검사간 신뢰도에서 space balance 3D의 정적균형과 동적균형은 중등도의 신뢰도를 보인반면, TMT의 세가지 점수와 버그균형척도는 높은 신뢰도를 보였다. 동시타당도에서 TMT의 세가지 점수, 버그균형척도, space balance 3D의 정적균형간에 각각 중등도의 유의한 (p<.01) 양의 상관관계를 보였다. TMT의 세가지 점수와 버그균형척도는 space balance 3D의 동적균형의 후좌측, 전좌측 방향과는 각각 유의한 (p<.05) 낮은 양의 상관관계를 보였지만 나머지 방향과는 유의한 상관관계를 보이지 않았다. 따라서 space balance 3D와 TMT의 균형 능력 평가는 아급성 뇌졸중 환자의 균형 능력을 평가하는데 유용하게 쓰일 수 있을 것으로 보이나 space balance 3D의 동적균형 평가는 한계점이 있었다.
