![]() Outcome: This test (Bilateral Straight Leg Raise Test) is positive if (a) the limb/joint positioning sequence reproduces symptoms associated with radiculopathy, (b) the sensitizing position reproduces symptoms, and (c) there is a repeatable and measurable asymmetry between both sides along with the reproduction of symptoms. Sensitizing position: Hip flexion (up to 90 degrees – as investigations (6-8) have shown that a large proportion of nerve root excursion occurs between 60 and 90 degrees of hip flexion).Hip flexion (to 50 degrees (5) or up to 60 degrees (6)), having the knees at full extension (with the examiner’s one hand holding the anterior aspect of the patient’s distal thigh and the other hand holding the posterior aspect of the patient’s ankle),.Neutral alignment at the cervical, thoracic and lumbar spine, while the patient is on supine lying,.Procedure: Perform the limb/joint positioning sequence in the following order: Purpose of Bilateral Straight Leg Raise Test : To test if the tension along the sciatic nerve, tibial nerve, L4,5,S1 nerve roots (1), conus medullaris (2), and the adjacent dura to the spinal cord (3) contribute to the neurologic symptoms associated with radiculopathy (4-6).Įxaminer position: Standing beside the examination table, facing the patient. ![]()
