Shoulder Instability

Ehlers-Danlos Syndrome (EDS) is a connective tissue disorder that can predispose individuals to shoulder instability. The inherent laxity and hypermobility of connective tissues in individuals with EDS can compromise the stability of the shoulder joint, increasing the risk of subluxations or dislocations. Due to the underlying structural abnormalities characteristic of EDS, even routine activities of daily living may put excessive strain on the shoulder joint, leading to instability.

Managing shoulder instability in individuals with EDS often requires a comprehensive approach that addresses both the underlying connective tissue disorder and the associated shoulder instability. This may include physical therapy to strengthen the surrounding muscles, joint stabilization exercises, and possibly surgical intervention in severe cases.

Repetitive overhead movements, prevalent in sports like swimming, volleyball, and tennis, can contribute to shoulder instability over time. These activities subject the shoulder joint to repetitive stress, gradually stretching the ligaments and tendons that provide stability. As these structures weaken, the risk of shoulder instability escalates, particularly during dynamic movements requiring the arm to be raised overhead.

Overuse injuries stemming from repetitive overhead movements can culminate in chronic instability, necessitating intervention to restore shoulder stability and function. Implementing biomechanical assessments and tailored exercise regimens aimed at strengthening shoulder stabilizers can mitigate the risk of instability and optimize shoulder performance.

Muscle imbalance and weakness around the shoulder joint can also contribute to shoulder instability. When the muscles that support and stabilize the shoulder, such as the rotator cuff muscles and the muscles of the shoulder blade (scapula), are weak or imbalanced, the joint may be more prone to instability. Weakness in these muscles can result from factors such as poor posture, muscle imbalances, or inadequate strength training.

Strengthening exercises targeting the muscles of the shoulder complex and improving overall shoulder biomechanics through physical therapy can help address muscle weakness and restore stability to the shoulder joint.
