Average muscle contributions to forward propulsion (i.e., horizontal pelvis acceleration) by the control subjects during the ipsilateral pre-swing phase and the hemiparetic subjects during the paretic pre-swing phase, where Total is the sum of the positive and negative contributions from all muscles for the respective leg. Contributions from the ipsilateral leg muscles to forward propulsion increased as walking speed increased from 0.6 to 0.9 m/s in the control subjects. Similarly, contributions from the paretic leg muscles (i.e., SOL, GAS and GMED) to forward propulsion increased with improved functional walking status. The non-paretic leg muscles (i.e., RF and VAS) contributed to forward propulsion in the limited community walkers to compensate for reduced paretic leg muscle contributions.
