Figure 9. SPM Results for V-GRF at slow walking speeds.
A) V-GRF on the prosthetic side evolution B) SPM F-value for V-GRF on the sound side C) V-GRF on the sound side evolution D) SPM F-value for V-GRF on the sound side (For A and C dotted line(…)=soft stiffness, dashed line(- -)=medium stiffness and continuous line(__)=firm stiffness) (For B and D dashed line represents p-value=0.01) (SPM: Statistical Parametric Mapping, V-GRF: vertical ground reaction force).
