The reliability of kinematic measurements has a top priority in gait analysis. The aim of the present work was to assess the inter-trial, inter-session and inter-examiner variability of an anatomical-based protocol by an established method. The gait of two young adult volunteers was analyzed by four examiners with different degrees of experience in three sessions 1 week apart. The data of five trials of level walking were collected and the rotations in the three anatomical planes of the pelvis, hip, knee and ankle were calculated. The mean value over the gait cycle of the standard deviation of these rotations was calculated for each of the 24 groups of five trials (inter-trial), the eight groups of five trials multiplied by three sessions (inter-session), and the two groups of five trials multiplied by three sessions multiplied by four examiners (inter-examiner). For each rotation, the inter-examiner variability was larger than the inter-session, and the latter larger than the inter-trial. The present ratio between inter-examiner and inter-trial variability was found to be smaller than that of the conventional protocol for each of the gait variables.
