Medical Conditions - Lever Sign Test

Lever sign test or Lelli's test is used to diagnose a rupture of the anterior cruciate ligament (ACL). It is done after an injury without much discomfort. The patient is made to lie in a supine position with both legs fully extended. One fist of the therapist is positioned under the proximal third of the calf, and with the other hand, a downforce is applied over the distal third of the patient's quadriceps. When the heels raise, the test is negative, and if the heel does not raise, the test is positive.
