This neural tension test can be used to rule out neural tissue involvement as a result of lumbar disc herniation.<ref name="Dutton">Dutton, M. (2008). Orthopaedic: Examination, evaluation, and intervention (2nd ed.). New York: The McGraw-Hill Companies, Inc.</ref>

When performing the straight leg raise test the patient is positioned supine in the absence of pillows.&nbsp; The clinician lifts the patient's symptomatic leg by the posterior ankle while keeping the knee in a fully extended position.&nbsp; The clinican continues to lift the patient's leg by flexing at the hip until pain is illicited or end range is reached.&nbsp; Neurologic pain which is reproduced in the leg and low back between 30-70 degrees of hip flexion is a positive result of lumbar disc herniation at the L4-S1 nerve roots.&nbsp; In order to make this test more spcific, the ankle can be dorsiflexed and the cervical spine flexed.<ref name="Dutton" />
