Evaluation of current perception threshold in the diagnosis of diabetic peripheral neuropathy / 中国神经精神疾病杂志

ABSTRACT

Objective To evaluate the diagnostic value of current perception threshold (CPT) for diabetic peripheral neuropathy by comparing with nerve conduction velocity (NCV). Methods Sixty patients with type 2 diabetes were enrolled. The CPT and SNCV were examined respectively. Results The abnormal rates of the CPT and SNCV were 68.33％and 36.67％in all patients, respectively. The abnormal rates of the CPT and SNCV were 88.46％and 53.85％in symptomatic group. The abnormal rates of the CPT and SNCV were 47.06％ 17.65％ in asymptomatic group. In patients with disease less than five years, the abnormal rates of the CPT and SNCV were 55.17％ and 24.14％. In patients with disease greater than five years, the abnormal rates of the CPT and SNCV were 77.42％ and 48.39％. The abnormal rate was statistically significant difference (P<0.05) between two examination. Conclusion CPT and NCV were consistency in the diagnosis of diabetic peripheral neuropathy. For early asymptomatic patients, CPT have more advantages to inspect the sub-clinical patients.
