Does the Impingement Test evaluate for capsular impingement or rotator cuff impingement?

The Impingement Test is specifically designed to assess rotator cuff impingement, particularly involving the supraspinatus tendon. This test evaluates the space between the acromion and the rotator cuff tendons. When the arm is raised, the tendon can become pinched against the acromion, leading to pain and functional limitations, which are classic signs of rotator cuff impingement.

Understanding the nature of rotator cuff impingement is crucial for physical therapists and healthcare providers when diagnosing shoulder issues, as it enables them to implement targeted treatment strategies to mitigate pain and restore function. While other tests or evaluations might assess the integrity of the shoulder capsule, the specific focus of the Impingement Test is on the interaction between the rotator cuff components and the structures above them, hence confirming its relevance to rotator cuff impingement specifically.
