Hip Orthopaedic Test: Femoral Nerve Tension Test

The prone knee bending test is a physical examination technique used to assess neural tension and stress on the femoral nerve and mid lumbar (L2-L4) nerve roots. Here are the steps to perform the prone knee bending test:

1. Have the patient lie down on their stomach on the examination table with their legs straight.
2. Flex the patient's affected knee to 90 degrees.
3. Apply pressure to the patient's ankle, pushing the foot towards the buttocks.
4. Observe the patient's face for any signs of pain or discomfort, and note any radiation of pain down the leg.

If the patient experiences pain or discomfort in the hip or radiation of pain down the leg during the test, this may indicate neural tension or stress on the femoral nerve and mid lumbar nerve roots. However, it is important to note that the prone knee bending test should be used in conjunction with other examination techniques and diagnostic tests to accurately diagnose nerve injuries.
