The purpose of this study was to investigate the reliability of repeated measurements and a possible learning or tiring process in single-limb stabilometry and one-leg hop test. An additional purpose was to study 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-limb stabilometry and one-leg hop test were found to have high reliability (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 correlation between the stabilometric variables was high (r=0.73–0.95, P<0.001).
