Scapular Retraction Test
The scapular retraction test is often used in conjunction with the dynamic labral shear test or the Jobe test to evaluate the potential role of scapular dyskinesis on supraspinatus strength and labral injuries.
This test was first described by Kibler et al. in 2009.
How do you perform the Scapular Retraction Test?
The patient is in the standing position. The examiner, standing behind the patient, places the fingers of one hand over the clavicle with the heel of the hand over the spine of the scapula to stabilize the clavicle and scapula and to hold the scapula stabilized in a fully retracted position. The examiner’s other hand compresses the scapula against the chest wall. Holding the scapula in this position provides a firm stable base for the rotator cuff muscles, and often rotator cuff strength (if tested by a second examiner) improves.
With the scapula in this position, the examiner performs the dynamic labral shear test to evaluate the glenoid labrum followed by the Jobe test to evaluate supraspinatus strength (empty can test or full can test; however, it is advisable to use the full can test position in the setting of a positive scapular assistance test to minimize symptoms of impingement which can decrease strength measurements).

What does a positive Scapular Retraction Test mean?
The test is considered positive when the above-described scapular manipulation decreases the symptoms associated with labral injury or rotator cuff impingement.
The test may also be positive in patients with a positive Jobe relocation test. If scapular retraction decreases the pain, when the Jobe relocation test is performed, it indicates that the weak scapular stabilizers must be addressed in the treatment.
A similar test has been described for the evaluation of infraspinatus strength in overhead athletes with scapular dyskinesis.

Scapular Reposition Test
The scapular reposition test was first described in 2008 by Tate et al. as a modification of the scapular retraction test. The investigators aimed to decrease the amount of retraction while also emphasizing increased posterior tilt and external rotation of the scapula.
In their study, the Neer sign, Hawkins–Kennedy test, and Jobe’s empty can test were performed in 142 collegiate-level asymptomatic athletes. If any of the above-mentioned tests were positive, each maneuver was repeated with the addition of manual scapular repositioning.

Manual scapular repositioning was performed by first manually grasping the top of the shoulder with the fingers over the AC joint and the thumb resting along the scapula spine. The examiner’s forearm was then obliquely positioned over the scapular body. The examiner then applied a moderate force to the scapula using both their hand and forearm to encourage increased posterior tilt and external rotation without achieving full retraction.
Following scapular manipulation, the Neer sign and Hawkins Kennedy test were repeated to assess for any change in shoulder symptoms and the Jobe test was repeated to assess for any change in rotator cuff strength. The intra-class correlation coefficients for the evaluation of rotator cuff strength (using Jobe’s empty can test) were above 0.95 when the scapula was in its original resting position and during manual repositioning. No other studies have evaluated the clinical utility of this test.
