What is the main purpose of the Hawkins-Kennedy Test?

The Hawkins-Kennedy Test is primarily designed to evaluate supraspinatus impingement, which involves the rotator cuff muscles of the shoulder, particularly the supraspinatus tendon. This test is performed by bringing the arm into flexion and then internally rotating it, which can create discomfort or pain if there is an impingement of the supraspinatus tendon beneath the acromion.

In the context of shoulder pathology, impingement is often a precursor to rotator cuff tears and can lead to significant functional limitations. By using this test, physical therapists and clinicians can assess whether there is an increased likelihood of impingement syndrome based on the patient's response during the maneuver.

Understanding the anatomy involved in the Hawkins-Kennedy Test is crucial, as it directly correlates with the space beneath the acromion where the supraspinatus tendon passes. Knowing how this specific test interacts with shoulder mechanics allows practitioners to focus their evaluations and treatments on relevant conditions affecting shoulder function.
