Scapular Upward Rotation
Movement of the scapula where the inferior angle moves laterally and the glenoid fossa tilts upward during arm elevation.
Full Definition
Scapular Upward Rotation is a three-dimensional movement of the scapula that occurs during shoulder elevation, characterized by the inferior angle moving away from the spine while the glenoid fossa tilts upward to maintain optimal glenohumeral joint mechanics. This motion is primarily controlled by the upper and lower trapezius and serratus anterior muscles working in coordinated fashion. Normal upward rotation ranges approximately 60 degrees during full shoulder elevation and is essential for maintaining subacromial space and preventing impingement. Dysfunction in scapular upward rotation is commonly observed in shoulder pathologies and can contribute to pain and functional limitations. Assessment involves visual observation, palpation, and goniometric measurement during active arm elevation movements.
Usage
Usage note: Specify direction (upward/downward) and distinguish from other scapular movements like elevation or protraction.
