Neurological impairment score in lumbar spinal stenosis
European Spine Journal, 03/19/2013 Evidence Based Medicine
Adamova BM et al. – Authors developed a scoring system [neurological impairment score in lumbar spinal stenosis (NIS–LSS)] for the assessment of neurological impairment in the lower limbs of patients with LSS, then performed a validation study to facilitate its implementation in the routine clinical evaluation of patients with LSS. The NIS–LSS is a simple and valid measure of neurological impairment in the lower limbs of patients with LSS (without comorbidity), discriminating them from healthy controls to a high degree of sensitivity and specificity and correlating closely with the degree of disability. It extends our ability to quantify neurological status and to follow changes arising out of the natural course of the disease or the effects of treatment.
