本文报道了一种测量正常人A δ纤维传导速度（CV）的新方法。一个大的正分量的体感诱发电位（SEP），其峰值潜伏期约为250毫秒，清楚地记录只有当强烈的电刺激引起明确的疼痛感施加到皮肤。通过测量远端刺激SEP和近端刺激SEP之间该成分的潜伏期差以及两个刺激部位之间的距离来计算周围神经的CV。在A delta纤维范围内，CV约为11.4 m/s（范围8.8 - 15.9 m/s）。在3名受试者中还观察到睡眠对疼痛相关SEP的影响。疼痛相关SEP波幅随睡眠阶段的进展而降低。这种方法简单、新颖，适用于大多数临床，对研究患者和正常人的周围神经生理功能有重要意义。
We report a simple new method for measuring the conduction velocity (CV) of A delta fibers in normal subjects. A large positive component of somatosensory evoked potential (SEP) whose peak latency was approximately 250 ms was clearly recorded only when strong electrical stimulation causing a definite painful feeling was applied to the skin. The CV of the peripheral nerve was calculated by measuring the latency difference of this component between the distal-stimulated SEP and proximal-stimulated SEP and the distance between two stimulus sites. The CV was approximately 11.4 m/s, (range 8.8-15.9 m/s), in the range of A delta fibers. The sleep effect on pain-related SEP was also observed in 3 subjects. The amplitude of pain-related SEP decreased with the progress of sleep stage. This simple and novel method is available in most clinics and should be very useful in investigating the physiologic functions of peripheral nerves in patients as well as normal subjects.
