Summary
Brief summary (as posted)
The goal of this observational study is to test the new kind of ultrasound-based measurements in patients with carpal tunnel syndrome. The main questions it aims to answer are: * Do the measurements of the size of the median nerve at the point where it is maximally compressed accurately diagnose carpal tunnel syndrome? * May these measurements accurately tell how severe is the carpal tunnel syndrome? Participants will be asked to: * Undergo conduction studies of median and ulnar nerve. * Undergo ultrasound of the median nerve. * Fill out the Boston carpal tunnel questionnaire and a demographic questionnaire. Researchers will compare the group of patients with carpal tunnel syndrome with healthy volunteers to see if respective measurements differ significantly between groups.
