Alterações eletroneuromiográficas em idosos com estenose de canal raquídeo lombar degenerativa: associação com as alterações de imagem e clínica

Ziegler, Marcus Sofia January 2012 (has links)
Made available in DSpace on 2013-08-07T18:56:36Z (GMT). No. of bitstreams: 1 000447975-Texto+Completo-0.pdf: 1984099 bytes, checksum: 6d01bc551f6e70cc3b595b1f0520916e (MD5) Previous issue date: 2012 / 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 é identificar o papel da eletroneuromiografia (ENMG) no diagnóstico da estenose de canal raquideo lombar degenerativa (ECRLD). Um estudo transversal prospectivo com coleta de dados envolvendo 31 pacientes com diagnóstico 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 medicação para alívio da dor. ECRLD não alterou a neurocondução ou a “Sympathetic Skin Response” SSR. A EMG confirmou alta frequência de radiculopatia, particularmente multiradiculopatia. As raízes de L5 e S1 foram as mais lesadas. Identificamos também uma alta prevalência de radiculopatia em L4. Correlacionando EMG aos achados clínicos, identificamos que a apresentação clínica, o ponto chave de início de uma avaliação, é pobre no que tange a identificar radiculopatia, frequente consequência da ECRLD. Por esta razão, acreditamos que a EMG pode ser uma ferramenta importante, visto que possibilita identificar se os sintomas são de natureza neurogênicos. Somado a isso, pode servir para focar o tratamento em um segmento específico da coluna vertebral.
