The author describes a method of measuring conduction velocity in sensory fibres based on averaged evoked potentials. In the method potentials are recorded with surface electrodes over the nerves of the upper extremity at three sites: wrist, elbow and branchial plexus. The further route of the central neuron was represented by two responses from the cervical spinal cord at the C2 level, and first component N1 of the cortical response. The method makes possible distinguishing of damage to the peripheral part from that to the central part of the sensory system. Checking of the method in 15 healthy subjects made possible determination of conduction velocity which was stable for all measuring points in the peripheral nerve and spinal cord and was 75 m/sec, while at the distance from the spinal cord to the cortex it was only 58 m/sec. The author discusses in detail the technique of recording and reading of evoked potentials, whose amplitudes may be below 0.5 microV and latency is read with an accuracy of 0.1 msec.
作者描述了一种基于平均诱发电位测量感觉纤维传导速度的方法。在该方法中，使用表面电极在三个部位记录上肢神经上的电位：手腕、肘部和臂丛神经。中枢神经元的进一步路径由来自C2水平颈脊髓的两种反应以及皮质反应的第一个成分N1表示。该方法能够区分感觉系统外周部分和中枢部分的损伤。在15名健康受试者中对该方法进行检测，得以确定传导速度，其在外周神经和脊髓的所有测量点均稳定，为75米/秒，而从脊髓到皮质的距离处仅为58米/秒。作者详细讨论了诱发电位的记录和读取技术，其振幅可能低于0.5微伏，潜伏期读取精度为0.1毫秒。
