Design outcomes

Primary

Measure	Time frame
The main parameter of this study will be the peak hip abduction moment, as the abductors of the hip will be most affected if the FAO is not restored properly (	—

Secondary

Measure	Time frame
Kinematics: Hip abduction/adduction moment, hip range of motion in the frontal/sagittal plane, pelvic tilt range of motion, peak hip extension/flexion, peak hip internal/external rotation Spatiotemperal variables: walking speed (at self-paced speed), stride length, cadence, step length, stance duration, single support, double support, cycle duration Neuromuscular parameters: EMG of the hip abductors and muscle strength of the abductors.	—
