Table 2.

The muscle parameters used in the AL 288-1 model. Origin coordinates are local to the proximal limb segment and insertion coordinates are local to the distal limb segment. The knee extensor passes through a midpoint at (0.040 m, 0.274 m) and the knee flexor through a midpoint at (−0.020 m, 0.252 m) local to the thigh
