STABILOMETRY AND ONE-LEG HOP TEST HAVE HIGH TEST-RETEST RELIABILITY

The purpose of this study was to investigate the reliability of repeat ed measurements and a possible learning or tiring process in single-li mb stabilometry and one-leg hop test. An additional purpose was to stu dy the correlation between different stabilometric variables. Seventy- five healthy subjects were examined twice with a median interval of 7 d, and with three consecutive measurements on each occasion. Single-li mb stabilometry and one-leg hop test were found to have high reliabili ty (ICC r = 0.68-0.83 and 0.96, respectively). The correlation between consecutive measurements was acceptable to high in stabilometry (r =0 .42-0.90, P = 0.002-P<0.001) and high in the one-leg hop test (r=0.91- 0.97, P<0.001). A learning process over time was observed. The correla tion between the stabilometric variables was high (r =0.73-0.95, P<0.0 01).
