Femoral nerve stretch test
Femoral Nerve Stretch Test
The Femoral Nerve Stretch Test (pronunciation: feh-moh-ral nərv strech test) is a clinical examination procedure used to evaluate the integrity of the L2, L3, and L4 nerve roots, primarily assessing the femoral nerve.
Etymology
The term "Femoral" is derived from the Latin word "femur" or "femoris" meaning "thigh", and "Nerve" from the Latin "nervus" meaning "sinew, tendon, nerve". "Stretch" comes from the Old English "streccan" meaning "to stretch, extend", and "Test" from the Old French "test" meaning "small vessel".
Procedure
The Femoral Nerve Stretch Test is performed with the patient in a prone position. The examiner flexes the knee of the patient to an angle of 90 degrees and then extends the hip. A positive test is indicated by pain in the anterior thigh, suggesting possible femoral nerve root impingement or lumbar radiculopathy.
