Comparison of knee flexion angle at initial contact (top row) and net nondimensional oxygen (O2) consumption (bottom row) with the internal knee extensor moment angular impulse, rectus femoris (RF) integrated area, and the rectus femoris and biceps femoris long head (RF-BFLH) co-contraction index. Regressions include children with bilateral CP without knee hyperextension. Note that only a subset of the children with CP (N = 389) had kinetic data collected during their gait analysis to evaluate the knee moment.
