Correlation of vitamin D levels with electrophysiological findings and pain in the patients with Carpal Tunnel Syndrome

BACKGROUND AND PURPOSE: This study aimed to assess the correlation between vitamin D deficiency and electrophysiological findings and pain level in patients with symptoms of carpal tunnel syndrome (CTS). METHODS: A total of 131 patients with symptoms of CTS, 70 with vitamin D deficiency and 61 without vitamin D deficiency, were included in the study. Using demographic data and findings from electrophysiological examinations, the patients were divided into two groups based on their vitamin D level (Group 1: <20 ng/ml; Group 2: ≥20 ng/ml). The Boston Carpal Tunnel Syndrome Questionnaire was used to assess their CTS- related pain level. RESULTS: Although the rate of CTS in the patients with a low vitamin D level was found to be high, no statistically significant correlation was observed between low vitamin D level and the frequency and severity of CTS. Additionally, the pain and functional loss ratio induced by CTS was found to be higher in the group with a lower vitamin D level than in the group with normal levels. CONCLUSION: Low vitamin D levels may increase the severity of CTS symptoms. Treatment of vitamin D deficiency in patients with CTS can play a role in reducing pain and disability.
