Abstract Background: There is no single test that defines properly lumbar spinal stenosis (LSS) diagnosis, and diagnosis of the syndrome continues to rely on clinical judgment. LSS symptoms may be broad and may be seen in multiple disorders in elderly. Hypothesis: To identify the role of electromyography and nerve-conduction studies on LSS diagnosis.
