The Biceps Load Test I primarily assesses for which type of shoulder pathology?

The Biceps Load Test I is specifically designed to evaluate for a SLAP lesion, which stands for Superior Labrum Anterior to Posterior tear. This test is grounded in the pathology's mechanics; SLAP lesions affect the superior labrum where the biceps tendon attaches.

During the assessment, the patient is positioned supine and is asked to perform an elbow flexion against resistance while the shoulder is placed in a specific position. If the test reproduces pain or the sensation of locking, catching, or an unfamiliar feeling in the shoulder during bicep contraction, it indicates a likely SLAP lesion.

This specificity is crucial, as SLAP lesions can be easily confused with other shoulder pathologies, but the unique mechanism of action involving the biceps tendon is what this test directly targets. Understanding this connection helps clinicians differentiate SLAP lesions from other conditions like rotator cuff tears or subacromial impingement, which have differing characteristics and required interventions.
