Dr. Stacie Barber | Physical Therapist + Strength Coach on Instagram: "Have you ever heard of the Lever Sign Test aka the Lelli’s test to check the integrity of the ACL? Clinicians tap in and let me know what you think of this test / if you use it below 👇 Negative test: When the ACL is intact the downward force applied over the quadriceps will cause the heel to rise. Positive test: With a damaged ACL the downward force will cause anterior translation of tibia in relation to the femoral condyle.
