What is a Femoral Nerve Entrapment?

, also known as femoral neuropathy or femoral nerve dysfunction, is when a patient’s femoral nerve is pinched, compressed, entrapped, or damaged, causing the patient’s loss of sensation or movement ability in the leg. If not identified or diagnosed right away, femoral nerve entrapment can:

  • Interfere with a patient’s walking ability
  • Negatively affect the sensation of a patient’s leg and foot
  • Prevent the flow of blood in a nerve that will result in damage to the tissue
  • Cause more injuries because weakness in one’s leg muscles can increase one’s risk of falling

To diagnose, a practitioner must conduct several physical exams, an interview, and additional tests such as CT scans, EMG, MRI, and nerve conduction.

One of the physical tests a practitioner can conduct is the femoral nerve entrapment test, also known as the prone knee bending test or reversed Lasègue test. The test helps practitioners check the femoral nerve up to the nerve roots of the upper lumbar spine (L2-L4).

How does this Femoral Nerve Test work?

Step One. Access the Template. 

Access and download the template by:

  • Clicking the “Use this Template” or “Download Template” button above
  • Searching for the “Femoral Nerve Test” in Carepatron’s template library on our website or app

Step Two. Conduct the Test

Before you begin, don’t forget to complete the required basic information, such as the patient’s name, your name, and the exam date. Afterward, you may proceed to follow the test instructions. 

Though you have a copy of the directions in the template, to help you prepare as early as now, we’ve written the step-by-step below. 

  1. Have your patient in a prone position or lying face down. You may provide a pillow to place under their abdomen for their comfort.
  2. Bend or flex the knee 90 degrees.
  3. Hyperflex the knee or push the ankle downwards or towards the buttocks.
  4. If the patient doesn’t show any symptoms, stabilize the hip with one hand, lift the knee, and push the ankle towards the buttocks once more.

Step Three. Interpret

Once finished with testing, record the patient’s results and findings. We’ve also provided the interpretation guide you’ll find on the template:

(+) Positive test if:

  • The patient feels a tightness in the anterior thigh
  • The patient feels a shooting, stabbing, or burning sensation symptomatic of nerve pain. 

Step Four. Proceed with Further Testing

As mentioned in the first section, this test isn’t enough to diagnose femoral nerve entrapment. So, it’s best to have them undergo several more physical exams, interviews, or imaging tests like CT scans, EMGs, and MRIs. 


To obtain a Femoral Nerve Entrapment Test Score, simply tick the negative or positive checkbox based on the interpretation that matches your observation.
