Traditional balance ability tests such as the one-leg stance with eyes closed (C-OLS) test is easy for young people to do, and many achieve an upper time limit. The aim of this study was to examine the distribution and reliability of the one-leg tiptoe stance with eyes closed test (C-OLTS), which is more difficult than C-OLS, as well as the relationship between C-OLS and C-OLTS. Ninety-eight female subjects performed C-OLS (two trials each) and C-OLTS (five trials each), and the time for which the posture was maintained was recorded. In both tests, the recorded time and its logarithmic conversion value were used in analysis because the distribution of both tests was not normal. The difference in C-OLTS scores among the trials was not significant, and the maximal time recorded for the test was 12.52s. The intra-class correlation coefficient (ICC) of C-OLTS was good (ICC = 0.77 ～ 0.88). In addition, the significant correlation coefficient (ρ = 0.46) between C-OLS and C-OLTS was confirmed. C-OLTS has substantial reliability and no ceiling effect. The open relationship of both tests may be influenced by various differences in test characteristics and suggest that affected ability to test performance is a little different between both tests.
