scapuladyskinesis

Scapuladyskinesis refers to abnormal movement or positioning of the scapula, commonly known as the shoulder blade. This condition involves a disruption in the coordinated action of the muscles that control the scapula's movement during arm elevation and other shoulder activities. Instead of moving smoothly along the thoracic cage, the scapula may exhibit excessive winging, tilting, elevation, or protraction. These aberrant movements can result from a variety of factors, including muscle weakness, imbalance, nerve impingement affecting the muscles that stabilize the scapula, or poor posture.

The underlying causes of scapuladyskinesis often include injury to the muscles responsible for scapular control, such as the serratus anterior, trapezius, or rhomboids. Rotator cuff issues can also indirectly lead to scapular dyskinesia due to altered biomechanics. Repetitive overhead activities and poor training techniques in athletes are frequently implicated.

Symptoms associated with scapuladyskinesis can vary but commonly include shoulder pain, clicking or popping sensations, a feeling of instability, and reduced range of motion or strength in the affected arm. The abnormal scapular position can also contribute to impingement syndromes. Diagnosis typically involves a physical examination assessing scapular motion during specific arm movements, along with strength and flexibility tests. Imaging studies may be used to rule out other underlying pathologies. Treatment focuses on addressing the root cause, often involving physical therapy to strengthen weakened muscles, improve neuromuscular control, and correct faulty movement patterns.
