Background : Discrepancies exist in the currently available data on the prevalence of diabetic neuropathy. Variations in the prevalence of diabetic neuropathy have reflected the different criteria used to form its diagnosis. The majority of diagnostic criteria are less practical in many routine clinical settings where there is a need for a simple assessment using widely available techniques to rapidly screen large numbers of patients. We already reported that the questionnaire of Fledman's two-step assessment was less useful in Koreans, because of the different expression of neuropathic symptoms. We Noosed a representative questionnaire which was based on patients' own complaints, and assessed its clinical availability.
Methods : Ninety diabetic patients(45 cases with diabetic neuropathy, 45 cases without
neuropathy) were included in this study. Diabetic neuropathy was diagnosed by
neurologic examination and nerve conduction velocity. The questionnaire consisted of 7
questions on foot sensation (pricking, lancinating, burning, numb), which are frequent complaints of diabetic patients. All subjects were assessed with the questionnaire.
1. The most sensitive symptom was tingling sensation (75.6%) and the least sensitive
fee was numbness(28.9%).
2. The most specific symptom was numbness(82.2%) and the least specific one was
3. If we would assume that three or more of symptoms were diagnostic, the sensitivity and specificity were 56.7% and 53.3%, respectively.
Conclusion : Our new questionnaire can be used as a screening test or a follow-up
tool for the diagnosis of diabetic peripheral neuropathy in Koreans.
