Twenty, otherwise unselected, subjects with Type II diabetes mellitus were studied using electroneurographic and electromyographic techniques. Latencies, conduction velocities, amplitude and duration of evoked responses and change of amplitude and duration over distance, as well as H reflex and ulnar F wave were determined for motor nerves. Latency to onset and peak of negative deflection and amplitude of the evoked action potential were determined for sensory nerves. Eleven subjects had amplitude and/or latency abnormalities of the sural, superficial peroneal, and median sensory nerves. One additional subject had abnormality of both the sural and superficial peroneal nerves. Five subjects had mononeuropathies and 2 of these also had membrane instability of the abductor hallucis muscle. Ten subjects had clinical or electrophysiologic findings compatible with carpal tunnel syndrome either as an isolated lesion or superimposed on underlying peripheral neuropathy. It was concluded that all subjects with abnormality of 3 sensory nerves (median, sural and superficial peroneal) had findings compatible with diabetic peripheral neuropathy and that additional electrodiagnostic studies (unless otherwise indicated) did not identify additional abnormalities diagnostic of peripheral neuropathy in the remaining subjects.
对20名未经过其他筛选的II型糖尿病患者采用神经电图和肌电图技术进行研究。测定运动神经的潜伏期、传导速度、诱发电位的幅度和持续时间以及幅度和持续时间随距离的变化，以及H反射和尺神经F波。测定感觉神经负向偏转起始和峰值的潜伏期以及诱发电动作电位的幅度。11名受试者腓肠神经、腓浅神经和正中感觉神经的幅度和/或潜伏期异常。另有1名受试者腓肠神经和腓浅神经均异常。5名受试者患有单神经病，其中2名还伴有拇展肌膜稳定性异常。10名受试者有与腕管综合征相符的临床或电生理表现，可为孤立性病变或叠加于潜在的周围神经病变之上。得出的结论是，所有3条感觉神经（正中神经、腓肠神经和腓浅神经）异常的受试者都有与糖尿病性周围神经病变相符的表现，并且额外的电诊断研究（除非另有说明）未在其余受试者中发现可诊断周围神经病变的其他异常。
