Lower limb joint and pelvis kinematics. The average root-mean-square deviation (RMSD) value between the joint kinematics curves estimated by the ML method and the gold standard are computed over the gait cycle and averaged across trials and subjects. The similarity between the curves obtained with the proposed ML method and the gold standard is assessed using the linear-fit method [25]. The coefficients of the linear interpolation were used to compare the curves in terms of shape similarity (), amplitude (angular coefficient, ), and offset (constant term, ). The average of and across trials and subjects is calculated for each gait speed.
