oot control$. Where foot controlsrequire high control forces, the p~h force exerted
by the leg depends on the thigh angle and the knee angle. Figure 22 specifks the mCZU!maximum
push at various knee and thigh angles. The maximum push is
at about the 160°angle, referred to as
the limiting angle. The values of Figure 22 apply to males onlyand shouldbe eomcted for femaies.
