Effects of Glycemic Control and Clinical Parameters on Tibial Nerve Conduction Latency in Diabetic Peripheral Neuropathy

This observational cross-sectional study aims to investigate the effects of glycemic control and clinical parameters on tibial nerve conduction latency in individuals with diabetic peripheral neuropathy. Adults aged 45 to 76 years with diabetic peripheral neuropathy will be evaluated at a neurology and clinical neurophysiology clinic. Data collection will include demographic and clinical characteristics, diabetes type and duration, fasting blood glucose, and HbA1c values obtained from routine clinical records. Participants will also be assessed using the Michigan Neuropathy Screening Instrument (MNSI), including both the questionnaire and physical examination components. Nerve conduction studies will be performed using standard electromyography procedures, and tibial nerve conduction latency will be recorded. The study will examine the relationship between tibial nerve conduction latency and glycemic control parameters, neuropathy screening scores, and diabetes duration. The findings may help improve early identification and clinical evaluation of diabetic peripheral neuropathy.
