INTRODUCTION
The purpose of this study is to provide a controlled trial looking at the risk of paraspinal hematoma formation following extensive paraspinal muscle electromyography.
METHODS
54 subjects ages 55-80 underwent MRI of the lumbar spine before or shortly after electromyography using the paraspinal mapping technique. A neuroradiologist, blinded to the temporal relationship between the EMG and MRI, reviewed the MRIs to look for hematomas in or around the paraspinal muscles.
RESULTS
Two MRIs demonstrated definite paraspinal hematomas, while 10 were found to have possible hematomas. All hematomas were < 15 mm, and none were close to any neural structures. There was no relationship between MRI evidence of hematoma and either the timing of the EMG or the use of aspirin or other nonsteroidal anti-inflammatory drugs.
CONCLUSIONS
Paraspinal electromyography can be considered safe in the general population and those taking nonsteroidal anti-inflammatory drugs.
简介
本研究旨在提供一项对照试验，观察广泛使用脊柱旁肌肌电图后脊柱旁血肿形成的风险。
方法
54 名年龄在 55-80 岁的受试者在接受脊柱旁肌映射技术的肌电图检查之前或之后不久接受了腰椎 MRI 检查。一位神经放射科医生对 MRI 进行了盲法评估，以寻找脊柱旁肌肉内或周围的血肿。
结果
两份 MRI 显示明确的脊柱旁血肿，10 份 MRI 显示可能的血肿。所有血肿均<15mm，且均远离任何神经结构。血肿的 MRI 证据与肌电图的时间或是否使用阿司匹林或其他非甾体抗炎药之间没有关系。
结论
在一般人群和服用非甾体抗炎药的人群中，脊柱旁肌电图检查可以认为是安全的。
