Shoulder stability refers to the ability of the shoulder joint to maintain its position and function effectively during movement. This stability is crucial for performing daily activities and sports, as the shoulder is one of the most mobile joints in the body. It relies on a combination of muscles, tendons, ligaments, and the structure of the glenoid and humerus to keep it secure. Several factors contribute to shoulder stability, including the strength of the rotator cuff muscles and the integrity of the surrounding ligaments. Weakness or injury in these areas can lead to instability, resulting in pain or limited range of motion. Proper conditioning and rehabilitation exercises can help improve shoulder stability and prevent injuries.
