  1. Kinematic data are presented in degrees as mean ± 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).
  2. 1: Maximum during stance; 2: Touch down (0% stance); 3: Minimum during stance; 4: Maximum in 50% stance; 5: Minimum during 0-10% stance; 6: Minimum during 50-100% stance; 7: Maximum in 50% stance; 8: ROM (Range Of Motion) = Difference between maximum and minimum during stance; 9: Maximum in a static standing position (+) Positive: no posterior tilt occurs from the neutral position.
