Fig. 2

Lower extremity kinematics calculated using the constrained (gold band) and unconstrained (purple band) models were similar to within 5°. Sagittal knee and hip kinematics had the strongest agreement (rxy ≥ 0.90), ankle sagittal kinematics fell just below our threshold for ‘substantially different’ (0.85 < rxy < 0.90), and hip abduction was only moderately correlated between the two kinematic models (0.65 < rxy < 0.71)
