Abstract: ObjectiveTo determine the test-retest reliability of active static and dynamic balance ability with the Korebalance^TM System in elderly people.Methods20 ambulatory elderly persons who can walk self-helping participated in this study. Measurements were performed through Korebalance^TM System for active static and dynamic balance ability. All tests were repeated 7 d after the initial test, the intra-class correlation coefficients (ICC) were used to determine the test-retest reliability of each balance test.ResultsThe ICC indicated that active static and dynamic test had good reliability （ICC=0.804～0.923）.ConclusionThe Korebalance^TM System had good reliability in active static and dynamic balance test.

Key words: active balance test, reliability, elderly
