目的：建立腭帆张肌（tensor veli palatini，TVP）肌电图的检查方法，获得并分析健康人TVP的肌电图（eletromyography，EMG）特征。方法20例健康成年人在鼻内窥镜介导下，以咽鼓管咽口腭裂前下约3mm作为电极插入点的中点，距该点上、下各约2～3mm作为电极插入上、下点分别插入电极，嘱受试者进行一系列的吞咽动作，记录吞咽时TVP的EMG波形，并比较不同电极插入点及不同扫描速度EMG的波形。结果电极位于TVP上点，扫描速度为5ms/div时，共记录20例受试者38侧TVP的EMG，该点能更准确且稳定地获得EMG图形；TVP收缩持续时间为0．863±0．255s，收缩产生的峰电压为445．100±246．808μV，其EMG波型为干扰相；吞咽时双侧TVP收缩同步，未观察到滞后现象。动作电位时程为9．142±2．178ms，动作电位的振幅为254．260±191．544μV，动作电位图形多为2～3相波形。结论电极位于TVP上点，扫描速度为5ms/div时，可以获得更稳定的EMG图形，并获得了正常成人TVP肌电参数的正常范围。

Objective To establish examination methods of electromyography (EMG) for tensor veli palatini (TVP) ,to obtain EMG values and EMG graphic patterns of TVP in normal healthy population .Methods A total of 20 healthy adults were selected for the study .Under the guidance of nasopharyngoscope ,especially designed elec-trode needles were inserted into different sites of TVP .All the 20 healthy adults were asked to perform series of swallowing and recorded the EMG values and EMG waveforms .Results At a scanning speed of 5 ms/div ,and with the TVP point as tie point ,the results of 20 healthy adults were obtained for 38 sides of TVP EMG .With the TVP contraction duration (0 .863 ± 0 .255 s) ,the peak voltage was produced by the contraction of 445 .100 ± 246 .808μV .The wave forms of EMG were considered as the interference .TVPs were observed bilaterally in synchroniza-tion with the contraction during swallowing .Action potential durations were 9 .142 ± 2 .178 ms ,and the amplitude of the action potential was 254 .260 ± 191 .544 μV .The action potential graphic configuration was multi -phasic with 2~3 waveforms .Conclusion This experimental study showed that when the TVP point was as tie point and the scanning speed was set at 5 ms/div record ,the results of action potentials were obtained more stable and clearer and the TVP normal values were also obtained for the normal population .
