Prone 0 – examination in the prone position with the lower limb in neutral rotation; Prone Ext – examination with the lower limb in external rotation; Prone Int – examination with the lower limb in internal rotation. No significant difference was found in the proportion of symmetric/asymmetric hip adduction between patients with scoliosis and the controls, irrespective the technique of examination.
