Scapulothoracic Dysrhythmia
Pronunciation: SKAP-yuh-lo-thor-AS-ik dis-RITH-mee-uh
Abnormal movement pattern of the shoulder blade against the chest wall during arm elevation.
Full Definition
Scapulothoracic dysrhythmia refers to altered or abnormal movement patterns of the scapula relative to the thoracic wall during shoulder motion. This condition often results from muscle imbalances, weakness of scapular stabilizers, or compensatory movement patterns following shoulder injury or surgery. The dysrhythmia can manifest as scapular winging, tilting, or altered timing of scapular movement during arm elevation. Recognition and treatment of this condition is crucial in shoulder rehabilitation as it can lead to impingement, pain, and functional limitations.
Usage
Usage note: More specific than 'scapular dyskinesis' which encompasses all abnormal scapular movements, not just rhythm disturbances.
