Objectives: To establish the average distal sensory latency and amplitude of the dorsal ulnar cutaneous nerve under controlled temperature and settings. Design: Dorsal ulnar cutaneous nerve conduction studies were performed with a bar electrode between the fourth and fifth metacarpals. The nerve was stimulated at 8 and 10cm from the active electrode. The temperature of the limbs under study was kept at 32 °C to 35 °C. Participants: Fifty-four arms of 27 subjects were studied. Results: Results showed that distal sensory latencies were normally distributed. The average distal sensory latencies at 8cm and 10cm were 1.84 ± .20msec and 2.09 ± .21msec, respectively, with average amplitudes of 26.5 ± 9.7µV and 23.5 ± 8.8µV. Comparison with a previously reported study in which the limb temperature was not controlled showed a statistically significant difference. Conclusion: It is important to use standardized technique and to measure and maintain optimal temperature of the arm under study to prevent erroneous results and misdiagnosis.
