Abstract

This study was performed to assess the relation of vibration perception threshol (VPT) and sensory nerve conduction velocity(SNCV) in diabetics and control, respecti vely. The subjects were 39 diabetics (22 men, 17 women) who consisted of 20 patients with neuropathy symptomS(complaining group) and 19 patients without neuropathy symptoms (noncomplaining group). The followings were obtained. 1. The duration of diabetes mellitus in complaining group was significantly longer than that of noncomplaining group(p<0.05). 2. VPT of thumb. Lateral malleolus and great toe in diabetics were significantly increased and SNCV of median. Ulnar and sural nerve were significantly delayed than those of control(p<0.01). 3. VPT of thumb and lateral malleolus in noncomplaining group were significantly increased and SNCV of median, radial and sural nerve were significantly delayed than of control (p<0 05) VPT of thumb, lateral malleolus and great toe in complaining group were significantly increased and SNCV of median, ulnar and sural nerve were significantly delayed than those of control(p<0.05). VPT of great toe in complaining group was significantly increased than that of noncomplaining group( P<0.05). 4. VPT test of thumb anf great toe were more sensitive and specific than ulnar SNCV test. The results suggest that measurement of VPT is a useful method in early diagnosis and follow-up of diabetic peripheral polyneuropathy.
