Purpose
The purpose of the Passive knee extension test is to measure tightness of the hamstring muscles Fredriksen H, Dagfinrud H, Jacobsen V, Maehlum S. Passive knee extension test to measure hamstring muscle tightness. Scandinavian journal of medicine &amp;amp;amp;amp;amp;amp;amp;amp; science in sports. 1997 Oct 1;7(5):279-82.
Technique
The patient is positioned supine with the hip of the tested leg in 90 of flexion.The contralateral leg stays flat on the examination table. the clinician extends the knee until reaching the maximal tolerable stretch of the hamstring muscle as indicated by the patient , with the ipsilateral hip remaining in 90 of flexion. The knee angle is then measured. Reurink G, Goudswaard GJ, Oomen HG, Moen MH, Tol JL, Verhaar JA, Weir A. Reliability of the active and passive knee extension test in acute hamstring injuries.

Goniometer Placment
The Axis of the goniometer should be places at the lateral epicondyle of the femur.
