Scapular Dyskinesis

Scapular dyskinesis refers to abnormal movement or dysfunction of the shoulder blade (scapula) during arm motion. The scapula plays a critical role in shoulder stability and proper arm movement. When the muscles surrounding the scapula are weak, imbalanced, or injured, it can lead to abnormal positioning or movement of the shoulder blade, which can contribute to shoulder pain, instability, and impaired function.

This condition often arises due to muscle imbalances, poor posture, or previous injuries. It can also occur as a result of overuse or repetitive movements, particularly in athletes who participate in sports involving overhead motions, such as swimming, baseball, or tennis.
