On physical examination, patients with have normal peripheral pulses. The neurologic exam, straight leg raise, and femoral nerve stretch are typically normal. Abnormal signs may be revealed if the patient is observed walking until they exhibit . For example, a positive "stoop test" is observed if bending forward or stooping while walking relieves symptoms. Occasionally, patients may have other signs such as sensory loss or gait changes.
