Having found a significant limitation of neural movement (66.6%) during SLR performed on the symptomatic side in patients with sub-acute lumbar intervertebral disc herniation (LIDH), we followed up on the same patients over 1.5 years to ascertain if changes in cord excursion accompany changes in clinical symptoms. 14 patients, who originally had sciatic symptoms due to subacute LIDH, were re-assessed both clinically and radiologically with a 1.5T magnetic resonance (MR) scanner. Displacement of the conus medullaris during the unilateral and bilateral SLR was quantified reliably with a randomized procedure and compared between maneuvers and with data from baseline. Multivariate regression models and backward variable selection method were employed to identify variables more strongly associated with decrease in low back pain and radicular symptoms.Purposes And Background
