Median Nerve Cross-Sectional Area and Body Weight in Carpal Tunnel Syndrome
Sponsor: Kayseri City Hospital
Summary
This study aims to evaluate the diagnostic accuracy of ultrasonographic measurements of the median nerve in patients with Carpal Tunnel Syndrome (CTS). While ultrasound is a common diagnostic tool, various physical factors can influence its results. The researchers will investigate how a patient's absolute body weight and Body Mass Index (BMI) affect the size of the median nerve cross-sectional area across different stages of disease severity. The goal is to determine if absolute body weight plays a 'masking' role that could lead to more precise diagnostic interpretations in clinical practice.

Interventions
High-Resolution Ultrasonography and Electrophysiological Evaluation
Participants underwent a high-resolution ultrasonographic examination using a high-frequency linear probe to measure the median nerve cross-sectional area (CSA) at the level of the pisiform bone. Subsequently, standardized electrophysiological evaluations (motor distal latency and sensory conduction velocity) were performed to classify CTS severity according to AAEM criteria.
