The biceps load test is used to find out the integrity of the superior labrum of the shoulder to see if there is a labral (or SLAP) tear.
With the biceps load test, a positive test doesn’t always mean there is a tear, and a negative doesn’t necessarily mean there isn’t one.
To perform the biceps load test, have your patient lie down in supine. Abduct the shoulder to 90 degrees, and externally rotate it into the “stop sign” position. Have their palm up and thumb towards their head. Ask the patient to flex pulling towards their head, against your resistance at the wrist. A positive test is when pain is increased or there is apprehension. It could mean there is a SLAP tear.
