| Abstract;The clinical usefulness of maximal nerve conduction velocity(NCV) and amplitude(Amp) in microneurography were investigated and compared with motor nerve conduction velocity(MCV). Intraobserver variability of NCV or Amp on repeated measurements was very low, and variability of MCV after weekly intervals was higher than that of NCV, but lower than that of Amp. Correlation between NCV and Amp was lower than between NCV and MCV, which suggested that NCV and Amp methods of evaluating the diabetic polyneuropathy were different. The average values of NCV, Amp, and MCV were significantly different between patients with and without numbness, retinopathy, or nephropathy except for NCV in cases with nephropathy. Amp was less sensitive than NCV and Amp for evaluating the duration of diabetes or blood glucose control. For the evaluation of subjects with or without numbness, NCV was more sensitive than MCV, and the combined use with NCV and Amp showed a higher abnormal rate than separate use. These results suggest that microneurography may be more useful than MCV for evaluating diabetic polyneuropathy especially in patients with numbness but normal MCV. (author abst.) |
