Predicted (light gray) vs. measured (dark gray) hip/knee acceleration ratios. Measured ratios represent averages across subjects and are shown with ±1 s.d. bars. Experimental differences in the ratio due to changing the posture from toe off (TO) to early swing (ES) were significant (p < 0.05, t-tests) for both RF and VM stimulation and reflect the trends predicted by the model.
