Fig. 2B. Mean values of forelimb segment angular excursions of typical sequences at symmetrical (A) and in-phase (B) gaits. Stance and swing phases are scaled to the same duration using the method of linear interpolation. Based on this method the data for each limb segment are smoothed but their characteristics are preserved. Note the uniformity of time schemes especially of segment displacements despite differences for example in shoulder joint angular excursions.
