The mean contribution to muscular support about the medial compartment for the standard model (red) and adjusted model (blue) across stance phase, with the knee flexion angle during stance phase for the (A) semitendinosus (B) gracilis and (C) semimembranosus.

Shaded regions indicate ± one standard error. Point by point p-values are also shown for each point of stance phase. Note the different scale of the vertical axis for the GR.
