Previous issue date: 2012-08-31 / The aim of this study is to identify the role of EMG-NCS on LSS diagnosis. A cross-sectional study with prospective data collection was conducted involving 31 symptomatic patients with LSS confirmed by MRI. 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. EMG confirmed high frequency of radiculopathy, particularly multiradiculopathy. L5 and S1 roots were the most susceptible to injuries. We also found a higher prevalence of L4 radiculopathy. Correlating EMG with clinical findings, we found that the clinical presentation, the most important starting point of an evaluation, is poor in terms of identifying radiculopathy, a frequent consequence of LSS. For this reason, we theorize that EMG may play an important role as a diagnostic tool, being useful in determining when symptoms are neurogenic in nature. In addition, it may serve to focus treatment only in the area where it is really necessary. / O objetivo deste estudo ? identificar o papel da eletroneuromiografia (ENMG) no diagn?stico da estenose de canal raquideo lombar degenerativa (ECRLD). Um estudo transversal prospectivo com coleta de dados envolvendo 31 pacientes com diagn?stico de ECRLD confirmado com RNM. Todos os pacientes apresentavam dor. 83,9% dos pacientes queixavam-se de dor moderada ou severa e 90% dos pacientes faziam uso de medica??o para al?vio da dor. ECRLD n?o alterou a neurocondu??o ou a Sympathetic Skin Response SSR. A EMG confirmou alta frequ?ncia de radiculopatia, particularmente multiradiculopatia. As ra?zes de L5 e S1 foram as mais lesadas. Identificamos tamb?m uma alta preval?ncia de radiculopatia em L4. Correlacionando EMG aos achados cl?nicos, identificamos que a apresenta??o cl?nica, o ponto chave de in?cio de uma avalia??o, ? pobre no que tange a identificar radiculopatia, frequente consequ?ncia da ECRLD. Por esta raz?o, acreditamos que a EMG pode ser uma ferramenta importante, visto que possibilita identificar se os sintomas s?o de natureza neurog?nicos. Somado a isso, pode servir para focar o tratamento em um segmento espec?fico da coluna vertebral.
