Fig. 6From: Understanding patient preference in prosthetic ankle stiffnessUnderlying trends elucidated by preference. Normalization of stiffness values by preference highlights underlying relationships between kinematic symmetry and VSPA stiffness, which are obscured when stiffness is normalized by weight. A Cross-leg RMS diff. ankle angle versus preference-normalized stiffness. Intra-subject averages for each speed and stiffness are plotted as individual points. Light lines show a second-order fit to all pooled intra-subject averages at each speed. B Cross-leg RMS diff. ankle angle versus weight-normalized stiffness.
