Reliability of the intra and inter-test measures with universal goniometer and podalic arthrometer of the active range of ankle inversion and eversion

The objective this study was to evaluate intra and inter-rater and inter-instruments reliability of ankle inversion and eversion active range of motion. The study included 100 healthy individuals (71 women and 29 men; ages: 21.32±2.83 years old; body mass: 60.40±4.95 kg; height: 1.66±0.04 m; and body mass index: 21.89±2.83 kg/m2), who were submitted to measurement of ankle inversion and eversion using the universal goniometer and podalic arthrometer. We used the intra-class correlation coefficient (ICC) and Pearson's test, considering a 5% significance level. The results of this study demonstrated one very strong intra-rater ICC (0.91≥0.99; p0.8; universal goniometer: ICC
