In addition, falling forcefully on the shoulder can cause acute symptoms. These traumatic tears predominantly affect the supraspinatus tendon or the rotator interval [37] and symptoms include severe pain that radiates through the arm, and limited range of motion, specifically during abduction of the shoulder. [40]
When the arm is raised, the subacromial space (gap between the anterior edge of the acromion and the head of the humerus) narrows; the supraspinatus muscle tendon passes through this space. [6] Anything that causes further narrowing has the tendency to impinge the tendon and cause an inflammatory response, resulting in impingement syndrome.
The rotator cuff includes muscles such as the supraspinatus muscle, the infraspinatus muscle, the teres minor muscle and the subscapularis muscle. The upper arm consists of the deltoids, biceps, as well as the triceps. Steps must be taken and precautions need to be made in order for the rotator cuffs to heal properly following surgery while ...
The supraspinatus forms part of the rotator cuff and is one of its most frequently damaged components, whether from acute injury or gradual degeneration. [7] Bad posture and age are leading risk factors, with a high prevalence of asymptomatic partial and full tears, as well as symptomatic syndromes with chronic pain.
Palpation of sternoclavicular joint, clavicle, acromioclavicular joint, subacromial bursa, bicipital tendon. Evaluation of passive and active range of motion: Neck range of motion should be assessed that may reveal a neck source of shoulder pain. The Apley scratch test specifically tests range of motion and in a normal exam, an individual ...
When performing the Neer impingement test, the elbow should be extended, humerus in internal rotation and the forearm pronated. When the examiner is passively flexing the arm forward, it is causing compression of the structures between the greater tuberosity, inferior acromion process and the acromioclavicular joint.
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

The Hawkins–Kennedy Test is a test used in the evaluation of orthopedic shoulder injury. It was first described in the 1980s by Canadians R. Hawkins and J. Kennedy, and a positive test is most likely indicative of damage to the tendon of the supraspinatus muscle. [1] [2]
