Diagnostic Accuracy of Different Bedside Clinical Methods in Evaluation of Peripheral Neuropathy in Patients of Diabetes: Experience at a Tertiary Care Center

ABSTRACT

Background and Objectives: At present, the gold standard for diagnosis of diabetic peripheral neuropathy is biothesiometry. Sincethe data are sparse comparing the biothesiometry with commonly used bedside tests, we conducted this study to evaluate theclinical accuracy of simple bedside clinical screening tools for evaluation of peripheral neuropathy in patients of diabetes mellitus.Materials and Methods: Atotal of 120 patients with diabetes mellitus referred from the endocrinology department, from August2014 to July 2017 were included in this study. A detailed clinical assessment including diabetic neuropathy symptom (DNS)score, diabetic neuropathy examination (DNE) score, ankle reflex, vibration sensation with a 128 Hz tuning fork, and 10 gSemmes-Weinstein monofilament, and biothesiometry was done in all the subjects.Results: The prevalence of peripheral neuropathy was 36% with biothesiometry. Only 33.33% of patients followed foot carepractices in the study population. Monofilament was the most sensitive and accurate of all the diagnostic tests for the evaluationof peripheral neuropathy in diabetes patients. On statistical analysis correlations observed between the biothesiometry andthe DNE score (r = 0.572, P < 0.00018) and DNS score (r = 0.436, P < 0.0004) and absent tuning fork sensation (r = 0.510;P < 0.0007), monofilament sensation (r = 0.713; P < 0.0002) and ankle reflex (r = 0.456, P = 0.0002) were significant.Interpretation and Conclusions: we concluded that simple bedside tests are useful for diagnosing peripheral neuropathy indiabetes patients including those in whom foot care practices are not followed.
