                             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.
Materials and Methods: A cross-sectional study with prospective data collection was conducted. 31
symptomatic patients with LSS confirmed by MRI were evaluated with neurophysiology tests. We compared
symptoms and neurophysiologic findings.
Results: All patients reported pain, 83.9% of patients reported it to be moderate or severe and 90% of patients
took pain medication. LSS did not affect NCS or SSR. Electromyography confirmed high frequency of radiculopathy,
particularly multiradicul.. View More»
