What is Freiberg's test?
Freiberg’s Test: A Clinical Tool for Sciatic Nerve Assessment Introduction Freiberg’s Test is an orthopedic clinical examination technique used to detect sciatic nerve irritation, particularly due to piriformis syndrome. This test assesses the involvement of the sciatic nerve by reproducing symptoms through forced internal rotation of the extended hip. Freiberg’s Test is especially valuable when differentiating between true sciatica and piriformis-related sciatic symptoms, helping clinicians determine the origin of a patient's lower limb radiating pain. Purpose and Clinical Use The main objective of Freiberg’s Test is to evaluate sciatic nerve entrapment or irritation as it passes beneath or through the piriformis muscle. Since piriformis syndrome can mimic lumbar radiculopathy, this test becomes particularly relevant in outpatient physiotherapy or orthopedic evaluations, where distinguishing between spinal and peripheral nerve involvement is essential for correct diagnosis an...
