What is Ruland Biceps Squeeze Test?

Ruland Biceps Squeeze Test is used to check for distal biceps tendon avulsion. This test is similar to Thompson Test that is used in Achilles tendon rupture.

Biceps Squeeze Test was developed by Robert T Ruland in 20051.

Biceps Tendon Rupture

Biceps Tendon Rupture Symptoms:

The typical history includes a report of a sharp, tearing pain concurrent with an acute injury in the antecubital fossa.

Clinical findings vary depending on the extent of the rupture; whether it is partial or complete.

The objective findings may include:

  1. Ecchymosis in the antecubital fossa,
  2. A palpable defect of the distal biceps,
  3. Loss of strength of elbow flexion and grip, but especially a loss of forearm supination strength.

In active individuals, the normal recommendation is primary repair of the acute tendon avulsion. If not repaired, a 30% loss of elbow flexion and a 40% loss of supination strength can be expected2.

Postoperatively, the elbow is protected for 6–8 weeks, after which unrestricted range of motion and gentle strengthening exercises are initiated. Return to unrestricted activity is usually not allowed until nearly 6 months of healing has passed.
