The Femoral Nerve Tension Test records anterior thigh/hip symptom response and range behaviour during a femoral nerve-biased position. It can support assessment reasoning, but it should not be used alone to diagnose neural involvement.
A client may report anterior thigh symptoms, front-of-hip sensitivity or discomfort with prone knee bending. The Femoral Nerve Tension Test can help record ROM and symptom response in a controlled position.
Test name: Femoral Nerve Tension Test
Purpose: Assess ROM and symptom response in a femoral nerve-biased position
What it assesses: Anterior thigh symptom behaviour, knee flexion/hip position response and side comparison
Equipment: Measurz inclinometer if ROM is recorded
Key finding: Symptom response, side difference and knee/hip angle where recorded
Best used with: Knee prone heel-to-butt, hip extension, modified Thomas test, lumbar ROM and symptom history
Key limitation: It is not diagnostic on its own
The Femoral Nerve Tension Test is a neurodynamic-style assessment that biases the anterior thigh/femoral nerve region through hip and knee positioning. In a ROM-focused Measurz context, it is most useful when the movement professional records range, symptoms and side comparison.
It is used to document anterior thigh symptom response, side-to-side differences and how hip/knee positioning affects symptoms.
It records range and symptom behaviour in a femoral nerve-biased position. It does not diagnose femoral nerve pathology, lumbar pathology or anterior thigh pain source on its own.
This test is often performed passively or with assisted positioning. If the client actively moves into the position, record that clearly. Active and passive versions should not be compared as the same test.
Clients with anterior thigh symptoms, hip flexor sensitivity, lumbar-related symptom history, quadriceps/anterior thigh mobility concerns or side-to-side symptom differences.
Treatment table or mat, Measurz inclinometer if recording knee/hip angle, Measurz app and notes for symptom location, intensity and behaviour.
Position the client according to the selected femoral nerve tension protocol. Commonly, the test biases the anterior thigh by combining knee flexion and hip positioning while symptoms are monitored. Record the ROM angle if using Measurz, and document the symptom response rather than simply marking pass/fail.
Stop if symptoms are strong, spreading, concerning or not appropriate to continue.
Record ROM angle if used, side tested, symptom location, symptom intensity and whether symptoms change with position. Interpretation is stronger when compared with knee prone heel-to-butt, hip extension, modified Thomas test and symptom history.
Evidence level: Level 3, limited exact ROM norms.
There is no universal normative ROM value that should be applied to this test. Use side comparison, symptom response and repeated testing under the same method.
Recent literature on neurodynamic testing supports cautious interpretation and the need to combine findings with other assessment information. Neurodynamic tests may provide useful symptom-response information, but they should not be treated as stand-alone diagnostic tools.
Common errors include forcing the movement, failing to record symptom location, comparing active and passive versions directly, not controlling hip position and interpreting symptoms as a diagnosis.
Use this test to track anterior thigh symptom behaviour, compare sides and decide whether further hip, knee, lumbar or movement assessment is useful.
Record side, ROM angle if measured, pain score, symptom location, symptom quality, hip position, knee angle, active/passive method, comparison side, stopping reason and related hip/knee ROM findings.
