Abstract:
Objective To investigate the diagnostic value of F wave in diabetic peripheral neuropathy (DPN).Methods F and M wave parameters were measured in 106 patients with diabetes mellitus and 75 normal persons, including the minimum latency, duration, amplitude and area of F wave, and the amplitude and the area of M wave.Results (1) In the 30 patients with diabetes mellitus without peripheral neuropathy, there were 8 cases with prolonged the duration of F wave, 4 cases with prolonged the minimum latency of F wave, 2 cases with increased in the ratio of the area of F/M wave. (2) The minimum latency prolonged of F wave, the ratio of the amplitude of F/M wave and the ratio of the area of F/M wave significantly increased in the 76 patients with DPN, the duration of F wave prolonged in the mild DPN but no one revealed remarkable abnormal. (3) In the controls, the function of upper limit of the minimum latency of F wave (Y) and leg length (X) was Y=12.3+48.8X 2. Conclusion (1) F wave could be served as sensitive index to the early diagnosis of DPN, and might detect subclinical DPN. (2) The proximal nerve segment could be affected without the lesions of the distal nerve segment in patients with DPN, and it suggested that vascular factor plays an important role in the mechanism of DPN.
