![]() Excessive external rotation of the stride leg during foot placement is associated with anterior (front) shoulder instability, SLAP (labrum) tears of the shoulder, (that dreaded) UCL injury, and abdominal (obliques) strains.Insufficient stance leg internal rotation can lead to injuries in other joints.Hands separate in this phase as we prepare to cock the arm for the next phaseĭeviations (pathomechanics) in the stride phase that can lead to injury:.The stance leg hip rotates internally while the stride-leg hip simultaneously rotates externally. ![]() Gluteus maximus – the main buttocks muscle – assists in stabilizing the trunk and pelvis.Hip abductors of the stance leg initiate forward motion – followed by hip and knee extension.Stride leg, stance leg, and target should be in (mid)line with each other.Stride (front) foot is pointed towards the target.Stride phase starts when the hands separate at the end of the wind-up and ends when the lead foot strikes the ground. Knee hyperextension of the stance leg can be associated with the dread UCL (ulnar collateral ligament) tear of the throwing elbow – often the impetus for Tommy John surgery.Insufficient hip abductor strength or motor control is associated with labral tears in upper corner (posterosuperior) throwing shoulder.The stance-leg pelvis is level with or below the swing-leg pelvis – this position is possible with adequate hip abductor strength (a lateral hip muscle group that helps keep the pelvis level)ĭeviations (pathomechanics) in the wind up that can lead to injury:.Knee of stance leg is in slight flexion – this position is possible with adequate quadriceps strength.Center of gravity is over the stance (back) leg.Appropriate hip muscle activation – involving an integration of strength, motor control, balance, and coordination – are essential to appropriate pelvic and lower extremity positioning during this phase of throwing.
