Fig. 1From: Gait kinematics of the hip, pelvis, and trunk associated with external hip adduction moment in patients with secondary hip osteoarthritis: toward determination of the key point in gait modificationWaveforms of hip adduction-abduction angle, pelvic tilt, and trunk lean angles in the frontal plane during the stance phase for all patients. Positive values represent hip adduction (a), pelvic tilt toward the swing limb (b), and trunk lean toward the stance limb (c)Back to article page
