DIABETIC DISTAL SYMMETRIC POLYNEUROPATHY AND THE DIAGNOSTIC VALUE OF TIMED VIBRATION SENSE
Main Article Content
Abstract
Objective: To investigate the diagnostic value of timed vibration sense (TVS) using a 128 Hz tuning fork in DSPN patients with diabetes. Subjects and methods: 80 diabetic patients with DSPN and 80 diabetic patients without DSPN at Hanoi Medical University Hospital were evaluated for TVS and analyzed for relationships with clinical characteristics. Results: The mean age of the DSPN and non-DSPN groups was 61.10 and 57.59, respectively (p < 0.05). For patients under 60 years old TVS < 8 seconds has sensitivity and specificity with DSPN of 68.4% and 97.9%, respectively, while for patients aged 60 years old or older, TVS < 5 seconds has sensitivity and specificity of 66.7% and 75.0%, respectively. Conclusion: Quantitative TVS examination is a fast, convenient and more sensitive technique than qualitative methods in diagnosing DSPN. Therefore, it is necessary to apply it to clinical examination practice for early detection, contributing to improving the quality of life of patients.
