Significance Of Nerve Conduction Velocity In The Diagnosis Of The Patients With Diabetic Subclinical Peripheral Neuropathy

Objective: To explore the diagnostic value of nerve conduction velocity in patients with diabetic subclinical peripheral neuropathy. To evaluate the influence to the prognosis of diabetic subclinical peripheral neuropathy by giving an effective treatment in early stage.Data and Methods: Sixty patients with diabetes and thirty healthy people were divided into the DM group and control group. There were 25 men and 35 women in the DM group. The age was 43 to 75. The average was 57. The time of diabetes was 5 to 20. The average was 9. There were 12 men and 18 women in the control group. The age was 43 to 74.The average was 56. It had no evident difference between the two groups in sex and age. The motor nerve conduction velocity (MCV) of the madian, ulnar, common peroneal, tibial nerves and the sensory nerve conduction velocity (SCV) of the madian, ulnar, sural nerves were measured in the two groups. The apparatus we used was the Keypoint evoked-potential electro- -myography that was made in Danmark. The temperature was 20℃to 25℃. The intensity was 3mv to 50mv. We regarded the standard from the PeKing Union Medical College hospital as a normal. The abnormal was the person who had not less than one nerve of the MCV or SCV lowing the normal. (positive) The contrast value between the two groups was examined by X2 test.Results:1 The abnormal persons in the DM group were 29. The abnormality rate was 48.33%. The abnormal person in the control group was 1. The abnormality rate was 3.33%. A significant difference was noted between the two groups.(X~2=18.225, P<0.01)...
