# Femoral Nerve Tension Test

The Femoral Nerve Tension Test requires controlled prone/side-lying positioning, symptom recording, knee/hip movement notes and cautious interpretation.

The Femoral Nerve Tension Test assesses symptom response when the femoral nerve pathway is loaded through knee flexion and hip extension positioning. It may reproduce anterior thigh, groin or neural-type symptoms in some clients. The test should be interpreted with symptom quality, side comparison, lumbar findings, hip and knee ROM, and neurological screening where relevant.

## Introduction

A client may report anterior thigh symptoms, groin discomfort, altered sensation or symptoms that change with lumbar, hip or knee position. The Femoral Nerve Tension Test can help assess whether anterior thigh symptoms are influenced by femoral nerve pathway loading.

This test should not be forced. The aim is to record symptom behaviour, not to create unnecessary irritation.

## Quick Summary

Test name: Range of Motion Femoral Nerve Tension Test  
Also known as: Femoral nerve stretch test, prone knee bend test  
Purpose: Assess anterior thigh or femoral nerve pathway symptom response  
Movement/position: Knee flexion with hip position adjusted to load the femoral nerve pathway  
Joint/body region: Lumbar spine, hip, knee and anterior thigh  
ROM type: Neurodynamic symptom response test  
Score: Positive/negative/unclear response, pain score, symptom location and movement angle if measured  
Equipment: Treatment table, pain scale, inclinometer or goniometer if measuring range, and Measurz  
Best used with: Slump Test, Straight Leg Raise, hip extension, knee flexion, lumbar ROM and neurological screen  
Key limitation: Quadriceps stretch and knee symptoms can be confused with neural symptoms

## What Is the Femoral Nerve Tension Test?

The Femoral Nerve Tension Test is a neurodynamic test that loads the femoral nerve pathway. It is commonly performed in prone or side-lying by flexing the knee and adjusting hip position.

The test may reproduce anterior thigh or neural-type symptoms. Interpretation depends on symptom location, symptom familiarity, side comparison and response to sensitising or easing movements.

## Why It Is Used

The test is used when anterior thigh symptoms, groin symptoms or upper-lumbar-related symptom behaviour may be relevant.

It may help inform:

Anterior thigh symptom assessment  
Neurodynamic mobility monitoring  
Lumbar and hip movement reasoning  
Side-to-side comparison  
Pain and symptom response tracking  
Progress across sessions

## What It Measures

The test measures symptom response to femoral nerve pathway loading.

It may be influenced by:

Knee flexion ROM  
Hip extension position  
Quadriceps length  
Femoral nerve mechanosensitivity  
Lumbar position  
Anterior thigh symptoms  
Knee symptoms  
Client irritability  
Professional technique

It does not confirm the source of symptoms on its own.

## Active vs Passive Range of Motion

This test is usually guided passively or actively assisted by the professional. If knee flexion angle or hip extension angle is measured, label the measurement clearly.

Do not record it as a standard quadriceps flexibility test unless that is the intended purpose and neural symptom response is not being assessed.

## Who It Is Useful For

This test may be useful for clients with anterior thigh symptoms, groin/anterior thigh neural-type symptoms, symptoms influenced by lumbar movement, or unclear differences between quadriceps stretch and neural symptoms.

## Equipment Required

Treatment table or mat  
Pain scale  
Goniometer or inclinometer if measuring angle  
Measurz for recording symptoms and ROM  
Optional neurological screen notes  
Optional comparison side notes

## Step-by-Step Protocol or How to Apply This in Practice

### Starting position

Position the client prone or side-lying according to the selected protocol.

### Client position

For prone testing, the client lies face down with the tested limb relaxed. For side-lying testing, the client lies with the tested side uppermost or according to the chosen method.

### Professional position

Stand beside the tested limb and monitor pelvis, hip and knee position.

### Body/joint setup

Start with the hip and knee relaxed.

### Stabilisation

Stabilise the pelvis to avoid lumbar extension, pelvic rotation or compensation.

### Movement instruction

Gradually flex the knee. If appropriate, add hip extension or adjust the hip position to increase femoral nerve pathway loading.

### Sensitising or easing movements

Changing hip position, knee flexion angle or cervical/lumbar position may alter symptoms. Record any change clearly.

### What to ask

Ask about anterior thigh stretch, knee discomfort, groin symptoms, tingling, burning, numbness, pain location and whether symptoms are familiar.

### Stopping rules

Stop if symptoms increase sharply, neurological symptoms worsen, pain is not tolerated or symptoms are slow to settle.

### What to record

Record side, knee flexion angle if measured, hip position, pain score, symptom location, symptom quality, sensitising response, easing response and comparison side.

### Number of trials

Use minimal repetitions when symptoms are irritable. Avoid repeated provocative testing.

### Retest consistency

Use the same position, sequence, endpoint, device and symptom criteria each session.

## Scoring and Interpretation

The test may be recorded as positive, negative, unclear or unable to test, but symptom details are more useful than the label alone.

A meaningful response may include familiar anterior thigh, groin or neural-type symptoms that change with sensitising or easing movements.

Interpretation is stronger when paired with:

Knee flexion ROM  
Hip extension ROM  
Lumbar ROM  
Neurological screen  
Straight Leg Raise  
Slump Test  
Symptom distribution  
Side-to-side comparison

Quadriceps stretch alone should not be treated as a neural response.

## Normative Data, Benchmarks or Reference Values

Evidence level: **Level 3 — this is a symptom response test rather than a normative ROM test.**

Practical benchmarks:

Side-to-side comparison  
Knee flexion angle at symptom onset  
Hip position at symptom onset  
Pain score  
Symptom quality  
Response to easing or sensitising movements  
Retest change across sessions  
Related knee, hip and lumbar findings

## Reliability and Validity

A 2020 diagnostic validity study of neurodynamic and orthopaedic tension tests investigated femoral nerve-related testing alongside other lumbar and lumbosacral radiculopathy tests, supporting the need for broader test clusters rather than isolated interpretation. ([mdpi.com](https://mdpi.com))

The Femoral Nerve Tension Test is less frequently studied than SLR because upper lumbar presentations are less common, so exact interpretation should be cautious and based on symptom behaviour and associated findings.

## Common Errors and Testing Limitations

Common errors include confusing quadriceps stretch with neural symptoms, forcing knee flexion, not recording hip position, allowing pelvic rotation, ignoring knee pain, failing to compare sides and repeating the test excessively.

Limitations include symptom overlap, quadriceps length contribution, knee ROM restriction, lumbar influence, client irritability and variable protocols.

## Practical Applications

Use the Femoral Nerve Tension Test to record anterior thigh symptom behaviour and support broader reasoning around lumbar, hip, knee and neural movement findings.

## How to Record This in Measurz

In Measurz, record the test side, result, pain score, symptom location, symptom quality, knee flexion angle, hip position, test position, sensitising response, easing response and comparison side.

Track change across sessions and compare with knee flexion, hip extension, lumbar ROM, Slump, SLR and neurological findings.

## FAQs

### What does the Femoral Nerve Tension Test assess?

It assesses symptom response to femoral nerve pathway loading through hip and knee positioning.

### Is anterior thigh stretch always positive?

No. A quadriceps stretch response is not the same as familiar neural-type symptoms.

### Can this test diagnose a condition?

No. It supports clinical reasoning but does not diagnose a condition by itself.

### What should be recorded?

Record side, pain, symptom location, knee angle, hip position and response to easing or sensitising movements.

### How should it be tracked?

Use the same position, sequence, endpoint and symptom criteria each session.

## Key Takeaways

The Femoral Nerve Tension Test assesses anterior thigh symptom behaviour.  
Quadriceps stretch and neural-type symptoms must be distinguished.  
Record knee angle and hip position when possible.  
Interpret with lumbar, hip, knee and neurological findings.  
Measurz should capture symptoms, side, angle, position and response.
