Sensory nerve conduction velocities in the cutaneous afferents of the ulnar and peroneal nerves of the neurologically normal adult dog were determined by stimulation at stimulus intensities of 15, 20 and 25 V through subcutaneously placed electrodes and by the averaged evoked response technique. Stimulus intensities of 15 V for the ulnar nerve and 20 V for the peroneal nerve were adequate to measure the sensory nerve conduction velocities of these nerves. A linear relationship was seen between sensory nerve conduction velocity (y in m/s) and tissue temperature (x in degree C) and the regression equations were expressed as follows: y = 1.6x + 12.3 at a stimulus intensity of 15 V for the ulnar nerve and y = 2.0x - 10.6 at 20 V for the peroneal nerve, respectively. The 95% confidence limits of the regressions of the sensory nerve conduction velocities against tissue temperature, obtained at a stimulus intensity of 15 V for the ulnar nerve or at a stimulus intensity of 20 V for the peroneal nerve, were proposed for a tissue temperature-dependent reference range to enable the clinician to evaluate graphically the sensory nerve conduction velocity in a diseased dog.
通过皮下放置电极，以15、20和25伏的刺激强度进行刺激，并采用平均诱发电位技术，测定了神经功能正常的成年犬尺神经和腓神经皮肤传入纤维的感觉神经传导速度。尺神经15伏、腓神经20伏的刺激强度足以测量这些神经的感觉神经传导速度。感觉神经传导速度（y，单位为米/秒）与组织温度（x，单位为摄氏度）之间呈线性关系，回归方程如下：尺神经在15伏刺激强度下，y = 1.6x + 12.3；腓神经在20伏刺激强度下，y = 2.0x - 10.6。提出了在尺神经15伏刺激强度或腓神经20伏刺激强度下获得的感觉神经传导速度对组织温度回归的95%置信限，作为与组织温度相关的参考范围，以便临床医生能够通过图形评估患病犬的感觉神经传导速度。
