Figure 2. COMa sorted by Pp.

Sorting by Pp yields three distinctly different acceleration profiles, although the double support phase (shaded area) are similar in shape. The low Pp group (b) generates very little acceleration in the double support phase. However, the high Pp group (c) demonstrates only positive acceleration through the first half of the gait cycle, while remaining negative throughout late double support and swing. These profiles potentially indicate different treatments focusing on increasing propulsive force in the low Pp group while the high Pp group may benefit from swing initiation assistance to prevent prolonged negative acceleration.
