Purpose[edit | edit source]

Quadriceps muscle.jpg

The extension resistance test is used to perform a maximal provocation on the muscle-tendon mechanism of the extensor muscles (Quadriceps femoris).

  • The extension resistance test is positive when the affected knee shows less power to hold the pressure. If positive we can say the extensor mechanism of the knee is disturbed.[1]

Technique[edit | edit source]

Knee Extension ( tests grade 3-thru 5)

1. Ask patient to sit up straight and support trunk with arms propped with no greater

than 20 degree of trunk extension. 2. The therapist may put their hand or a rolled towel

under the distal end of the thigh to cushion it.

3. Ask patient to extend the knee.

4. Place the knee in 20° of flexion from full extension to avoid mechanical locking of the

joint.

5. Apply resistance just proximal to the ankle.

NB. For a grade of 3 the patient should be able to actively extend the knee from 90o of flexion without a swinging motion secondary to flexing the knee and creating momentum[2]. This test is not appropriate for a grades 0-2.
In the video (R), resisted testing of knee starts at 4m30s.
