目的/引言虽然使用标准肌电图系统（EMGS）的神经传导研究（NCS）被认为是评价糖尿病多发性神经病变的金标准，但这种检查需要昂贵的设备和训练有素的技术人员。我们的目的是验证一种即时设备，NC-stat/DPNCheck（TM），该设备已被开发用于糖尿病多发性神经病的NCS的广泛使用。材料与方法糖尿病患者接受了两种NCS：DPNCheck（TM）和肌电图系统。DPNCheck（TM）的组间/组内信度也由组内相关系数确定。结果共对57例患者进行了评价。腓肠神经传导速度与腓肠神经动作电位波幅的相关系数分别为0.7734和0.6155。组内相关系数为0.767、0.811;组间相关系数为0.974、0.834。结论床旁肌电仪具有良好的重复性，与标准肌电仪具有良好的一致性。该设备可能是有用的，以评估糖尿病多发性神经病变。
Aims/Introduction Although nerve conduction study (NCS) using a standard electromyography system (EMGS) is considered to be the gold standard in evaluating diabetic polyneuropathy, this examination requires expensive equipment and well-trained technicians. We aimed to validate a point-of-care device, NC-stat/DPNCheck (TM), that has been developed for widespread use of NCS in diabetic polyneuropathy. Materials and Methods Diabetes patients underwent two kinds of NCS: DPNCheck (TM) and electromyography system. Inter-/intrarater reliability of DPNCheck (TM) were also determined by the intraclass correlation coefficient. Results A total of 57 patients were evaluated. The parameters of NCS between the two methods correlated well (r = 0.7734 for the sural nerve conduction velocity, r = 0.6155 for the amplitude of sural nerve action potential). The intraclass correlation coefficients were excellent (intrarater: the velocity 0.767, the amplitude 0.811; interrater: the velocity 0.974, the amplitude 0.834). Conclusions The point-of-care device has excellent reproducibility and good agreement with standard electromyography system. The device might be useful to evaluate diabetic polyneuropathy.
