Relationship between first MTPJ transverse plane position (°) in natural double leg up-right posture and in forced turnout (N = 18). Note: An abducted first MTPJ is a positive value, and these values are classified as normal (< 15°), ‘mild’ (15–20°), ‘moderate’ (21–39°), and ‘severe’ (≥ 40°) in keeping with Piqué-Vidal & Vila [33]
