Dynamic Ultrasound Evaluation Supraspinatus Tendon Injuries Using a Pilates Elastic Band.

Supraspinatus tendon tears are a common cause of shoulder pain and dysfunction. Although magnetic resonance imaging and computed tomography arthrography are still considered the gold standard, ultrasound offers a reliable, accessible, and radiation-free alternative. However, identifying tears can be challenging, particularly for less experienced operators. This technical note describes a simple dynamic ultrasound maneuver employing a Pilates elastic band. With the patient in a modified Crass position, the band is secured around the pelvis to provide controlled resistance during active lateral elevation of the shoulder. This loading mobilizes joint fluid and applies physiological stress to the tendon, thereby enhancing visualization of tears through gapping or altered gliding. This simple, well-tolerated technique could improve diagnostic accuracy, as well as guiding rehabilitation and surgical decisions.
