This examination technique involves a patient pressing their hands against their abdomen while attempting to maintain shoulder external rotation. The inability to maintain this position, with the elbow dropping posteriorly, indicates a potential subscapularis muscle tear or weakness. For instance, during the assessment, if a patient’s elbow drifts back despite the abdominal pressure, it suggests compromised functionality of the tested muscle.
The assessment of the subscapularis is crucial for a complete shoulder evaluation, contributing to accurate diagnosis and subsequent treatment planning. Historically, isolated subscapularis tears were difficult to identify. This clinical maneuver, along with other tests and imaging modalities, aids in identifying such injuries, which is critical for restoring optimal shoulder function and preventing further complications.
