Refining Shoulder Diagnostics: A Technical Note on Scapular Physical Examination

Abstract

Normal scapulothoracic function relies on a delicate balance among several periscapular muscles and is essential for shoulder motion. Disturbance in this balance can lead to abnormal motion, which can impair shoulder function, leading to pain and discomfort. A thorough scapular examination requires an accurate physical assessment and the ability to identify pathologies, such as muscle paralysis (e.g., trapezius or serratus anterior) and hyperactivity (e.g., pectoralis minor). Overall, a comprehensive approach to the physical examination is critical in accurately diagnosing and effectively treating shoulder and scapular pathologies. The purpose of this technical note is to provide a concise, standardized methodology for performing a comprehensive scapular examination, focusing on key clinical tests, anatomical landmarks, and motion patterns.
