Rotator Cuff Injuries: The Shoulder’s Impossible Dual Demand The golf swing requires the shoulder to simultaneously provide extreme mobility allowing the massive range of motion necessary for proper swing mechanics while maintaining the stability preventing injury during the violent forces at impact. This mobility-stability paradox proves particularly challenging for the lead shoulder (left for right-handed golfers) which must move through extraordinary ranges during the swing while absorbing deceleration forces and maintaining control through impact. Rotator cuff pathology in golfers typically develops through cumulative microtrauma rather than acute tearing. The repetitive overhead positioning during backswing, the explosive acceleration forces during downswing, and the eccentric loading during follow-through create progressive tendon degeneration…
