Kinetic data are presented in N*m/kg ± one standard deviation (SD). The difference between the patients with external snapping hip (SESH) and healthy subjects (controls) are reported as 95% CI (95% confidence interval).
1: Maximum during stance; 2: Minimum during stance; 3: Minimum during 0-10% stance; 4: Minimum during 50-100% stance.
