Quantitative Sensory Test for the Detection of Diabetic Peripheral Neuropathy / 대한정형외과학회잡지

ABSTRACT

The aim of this study was to compare widely used quantitative sensory tests to evaluate the diabetic neuropathy(DN). We tested plantar sensation of 40 patients with diabetes mellitus(Group I 20 with neuropathic symtom, Group II 20 without symptom) using Semmes-Weinstein monofilament(touch sensation), Biothesiometer(vibration sensation) and EMG. This result was also compared with that of the control group. Eighty percent of Group I and thirty percent of Group II had abnormal EMG findings. Group I had decreased vibration and touch sensation. Comparison of vibration perception threshold(Biothesiometer) with touch pressure sensation(Semmes-Weinstein monofilament) showed that the test with Biothesiometer was relatively accurate, however it was complicated, time consuming and that the test with monofilament was simple and easily performed in the field even though it was relatively crude. 5.07 monofilament could be very effective in the eearly detection of diabetic neumpathy. In conclusion, we recommend 5.07 monofilament as a screening method of diabetic neuropathy and biothesiometer as its follow-up method.
