背景：磁共振成像通常用于诊断腰椎管狭窄症。一些没有症状的人有一个小腰椎管。电诊断用于诊断椎管狭窄已有60多年的历史，但我们还没有发现将电诊断用于该目的的盲法对照试验。本研究进行评估的关系，磁共振成像的措施和电诊断数据与临床综合征的椎管狭窄症。方法：150人之间的年龄在55岁和80岁，包括无症状的志愿者和腰椎磁共振成像的人，进行了临床检查，电诊断，磁共振成像。如果受试者患有神经肌肉疾病、骶骨癌或检查结果不充分，则将其排除，留下126名受试者进行最终分析。最后一组被分为三组--无背痛、机械性背痛和临床脊柱狭窄--基于检查医生的印象，对他们来说，磁共振成像和电诊断测试的结果是被掩盖的。脊柱外科医生也回顾了影像学和临床检查data.Results：检查医生的临床椎管狭窄的诊断显着相关的神经系统检查结果（p < 0.05）和脊柱外科医生的诊断（p < 0.001）。临床椎管狭窄的诊断与电诊断试验中纤维性颤动的存在也有显著相关性（p
Background: Magnetic resonance imaging is commonly used to diagnose lumbar spinal stenosis. Some persons without symptoms have a small lumbar spinal canal. Electrodiagnosis has been used to diagnose spinal stenosis for over sixty years, but we are aware of no masked, controlled trials of the use of electrodiagnosis for that purpose. This study was performed to evaluate the relationships of magnetic resonance imaging measures and electrodiagnostic data with the clinical syndrome of spinal stenosis.Methods: One hundred and fifty persons between the ages of fifty-five and eighty years old, including asymptomatic volunteers and persons referred for lumbar magnetic resonance imaging, underwent clinical examination, electrodiagnosis, and magnetic resonance imaging. Subjects were excluded if they had neuromuscular disease, sacral cancer, or inadequate test results, which left 126 subjects for the final analysis. The final cohort was divided into three groups-no back pain, mechanical back pain, and clinical spinal stenosis-on the basis of the impression of the examining physician, for whom the results of the magnetic resonance imaging and electrodiagnostic testing were masked. A spine surgeon also reviewed both the imaging and clinical examination data.Results: The examining physician's diagnosis of clinical spinal stenosis was significantly related to the neurological findings on examination (p < 0.05) and to the spine surgeon's diagnosis (p < 0.001). The diagnosis of clinical spinal stenosis was also significantly related to the presence of fibrillations on electrodiagnostic testing (p
