• lumbar or sacro-iliac joint stiffness
• poor co-ordination of movement or early fatigue associated with muscle weakness
• leg length discrepancy (LLD) which will affect pelvic motion and stride length. Note: LLD < 1.5 cm is usually not significant
• prolonged or delayed pronation or supination of the foot, which will alter the function of the leg and pelvis during the running cycle [Read more…]
