Electrodiagnostic evaluation of diaphragmatic function has consisted of phrenic nerve stimulation and surface or esophageal recordings of the electrical activity of the diaphragm. Needle electromyography of the diaphragm has rarely been reported because of the perceived danger of this procedure. We describe a new technique for needle electromyography of the diaphragm. An EMG electrode is placed in the costal insertion of the diaphragm under the 8th, 9th, or 10th rib cartilage, distant from the major vessels, pleura, lungs, and abdominal viscera. Diaphragmatic denervation was found in 42 of 81 patients using this method. There were no complications related to the procedure. Needle electromyography of the diaphragm provides important information in the diagnosis and management of respiratory dysfunction.
膈肌功能的电诊断评估包括膈神经刺激以及膈肌电活动的表面或食管记录。由于认为该操作存在危险，很少有关于膈肌针电极肌电图的报道。我们描述了一种用于膈肌针电极肌电图的新技术。将肌电图电极置于第8、9或10肋软骨下方膈肌的肋部附着点处，远离主要血管、胸膜、肺和腹部脏器。使用该方法在81例患者中有42例发现膈肌去神经支配。该操作未出现相关并发症。膈肌针电极肌电图在呼吸功能障碍的诊断和管理中提供重要信息。
