Each frame was examined by three observers who made two attempts.įor this purpose, a wire structure figure in the shape of a human lower limb was designed and measured in AutoCAD it was then recorded during a pendular motion with a video-camera placed at distance of 5 m and analyzed with Kinovea in the 4 perspectives (90°, 75°, 60° and 45°). A multiple approach was applied involving the analysis of the systematic error, with a two-way ANOVA 2x4 the relative reliability with Intraclass Correlation Coefficient (ICC) and the Coefficient of Variance (CV) (95% confidence interval) and the absolute reliability with the Standard Error (SE). The results indicate that the Kinovea software is a valid and reliable tool that is able to measure accurately at distances up to 5 m from the object and at an angle range of 90°–45°.
