Execution:
- The patient is asked to walk normally with a neutral foot angle
- The patient is asked to then internally rotate the foot to 15° while walking
- The patient is asked to subsequently walk with the foot externally rotated to 15°
Positive Outcome: Pain is elicited with increased foot progression angle or if baseline pain is exacerbated

| Comment: This dynamic assessment aims to reproduce or exacerbate symptoms by gait manipulation. Using foot progression angle walking, foot progression is modified by internal or external rotation, which translates to directed forces across the hip that modify or exacerbate symptoms. The abutment of the head- neck junction with internal rotation would presumably be linked to symptomatic gait in patients with FAI, which coincided with their finding of a positive internal FPAW in the study group confirmed to have FAI morphology. In contrast, patients with symptomatic hip instability exhibited a positive test with external FPAW, which may reproduce instability or symptoms of undercoverage | |||||
