Pre-/post-patching motion curves of thighs and calves in squatting. Note: The X-axis represented the number of frames (500 frames) taken for each action in this experiment. The Y-axis represents the spatial coordinates of marker in Optotrak Certus system. The data missed at location a, b, d, e, f, g, h, i, and the data bounced at location c, j, k. The missing data at a'–i' and bounced data at c', j', k' are imputed to complete and smooth data by the Patch Program
