Notes: 3D, 23 DOF gait model created by D.G. Thelen, Univ. of Wisconsin-Madison, and Ajay Seth,
Frank C. Anderson, and Scott L. Delp, Stanford University. Lower extremity joint defintions based on Delp et al. (1990).
Low back joint and anthropometry based on Anderson and Pandy (1999, 2001). Planar knee model of Yamaguchi and Zajac (1989).
Seth replaced tibia translation constraints with a CustomJoint for the knee and removed the patella to eliminate all kinematic constraints; insertions of the quadrucepts are handled with moving points in the tibia frame as defined by Delp 1990.
