Abstract:
Objective To study the value of contact heat evoked potentials (CHEPs) for the early diagnosis of diabetic peripheral polyneuropathy. Methods Seventy-five diabetic patients were examined by conventional nerve conduction velocity studies and then divided into 2 groups: diabetics with normal nerve conduction and diabetics with abnormal nerve conduction. Thirty-three normal subjects were used as controls. Toronto Clinical Neuropathy Sco-ring System was used to evaluate the patients. CHEPs were recorded using different stimulation intensities at different temperatures. Results The peak latencies of 45℃ , 50℃, 53℃ in diabetics with normal nerve conduction group were longer than those in normal control group, with a significant difference between the 2 groups(P<0.05). The peak latencies of diabetics were positively related to Toronto scores. Conclusion CHEPs could detect the impair-ment of diabetic peripheral nerve and reveal the impairment earlier than conventional nerve conduction velocity exami-nation, The prolongation of peak latency in diabetics group was significantly and positively related to clinical condi-tion.
