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.",[51,52,53],"Carpal Tunnel Syndrome","Entrapment Neuropathies","Median Nerve Compression",[21,55,56,57,58,59,60,61],"Median Nerve","Cross-Sectional Area","Body Weight","Body Mass Index (BMI)","Electromyography","Diagnostic Accuracy","Physical and Rehabilitation Medicine","NOT_YET_RECRUITING","2026-03-30",{"date":65,"type":66},"2026-04-02","ACTUAL",{"date":68,"type":47},"2026-04-01",{"date":70,"type":47},"2026-09-01",{"name":5,"class":6}]
