Execution:
- Patient is in supine lying position (without a pillow unlike shown in the video)
- The examiner passively flexes the patient’s hip joint while keeping the knee fully extended until symptoms occur
- Optional: The examiner can confirm that the symptoms are due to mechanosensitivity of the nervous tissue by slightly reducing the provocative hip flexion and by adding dorsiflexion (Bragard’s sign) or neck flexion (Neri sign)
Positive Outcome: Patient reports shooting pain down the leg before 60° of hip flexion

| Comment: A negative test can render the presence of radicular pain due to a disc hernia with nerve root compression at L4-S1 less likely. | |||||
