CN EMG study was performed in 30 patients with Duchenne Muscle Dystrophy. The frequency of Motor Unit Potential (MUP) with satellite components was reviewed. The amplitude and duration of individual components as well as the distance between main MUAP and satellite components were measured. The results were correlated with clinical data (duration of the disease, muscle force and wasting) and morphological (obtained from rectus femoris open biopsy). Satellite components were found in 34% of the MUP number. A positive correlation was found (p 0.001) between the duration of the complex MUP (main MUP with satellite components) and muscle force. There was no evident correlation between the morphological findings (muscle fibre regeneration and necrosis) and occurrence of satellite potentials. The diagnostic yield of satellite potentials in neuromuscular diseases in discussed.
对30例杜氏肌营养不良患者进行了针极肌电图（CN EMG）研究。回顾了带有卫星成分的运动单位电位（MUP）的频率。测量了各个成分的幅度和持续时间以及主运动单位动作电位（MUAP）与卫星成分之间的距离。将结果与临床数据（疾病持续时间、肌力和肌肉萎缩）以及形态学数据（取自股直肌开放活检）进行了关联分析。在34%的MUP数量中发现了卫星成分。复合MUP（带有卫星成分的主MUP）的持续时间与肌力之间存在正相关（p<0.001）。形态学发现（肌纤维再生和坏死）与卫星电位的出现之间没有明显相关性。文中讨论了卫星电位在神经肌肉疾病中的诊断价值。
