Functional tests, such as the empty can test at 90 degrees, specifically target the supraspinatus tendon. Beyond this point, the scapula must rotate upwardly rotated by the trapezius and serratus anterior muscles, a process known as scapulohumeral rhythm, to allow the arm to continue moving upward without impingement.
90 Degree Shoulder Abduction Exercises: Essential Techniques for Mobility and Strength
The infraspinatus and teres minor externally rotate the humerus, which is necessary to clear the greater tubercle from the acromion. Understanding the Anatomy of Shoulder Abduction The shoulder joint, or glenohumeral joint, is a ball-and-socket configuration that provides an exceptional range of motion at the expense of inherent stability.
This condition occurs when the tendons of the rotator cuff or the subacromial bursa are compressed between the humeral head and the acromion process of the scapula. Rehabilitation and Strengthening Strategies Restoring and maintaining 90 degrees of pain-free shoulder abduction is a primary goal in rehabilitation.
Effective 90 Degree Shoulder Abduction Exercises for Mobility and Strength
Observing the scapular position during movement is equally important, as a dysynchronous or elevated scapula often indicates a kinetic chain dysfunction requiring correction. Assessing Range of Motion and Function Clinicians and fitness professionals utilize specific tests to evaluate 90 degree shoulder abduction.
