Biceps Squeeze Test
Purpose[edit | edit source]
The Biceps Squeeze Test is a Diagnostic test for distal biceps tendon rupture.
Technique[edit | edit source]
Step 1. Patient position in sitting with the forearm comfortably supported on the patient's lap.
Step 2. Elbow is flexed approximately 60-80 degrees (at this level of flexion stress on the brachialis minimizes and helps isolate the biceps from forearm supination).
Step 3. The forearm is slightly pronated and the examiner stands on the side of the limb to be examined.
Step 4. The examiner squeezed biceps brachii firmly with both hands, one hand on the myotendinous junction and the other around the muscle belly (when biceps brachii squeezed, deformation of the proximal muscle should create tension in the distal tendon resulting in forearm supination. This would not occur if the distal tendon is avulsed from its insertion on the radius.)[1]
Step 5. A positive test indicates the absence of supination of the forearm during the test shows a rupture of the distal biceps tendon.
Evidence[edit | edit source]
The study was done in 2005 resulting in 23 patients were tested positive out of 24 patients which shows the sensitivity of 96%.[1]
