A Study Using Dynamic Ultrasound to Enhance the Understanding of Carpal Tunnel Syndrome

Overview

About this study

The purpose of this study is to use ultrasound to detect variations in nerve, tendon and subsynovial connective tissue mobility in patients with carpal tunnel syndrome may be useful as functional biomarkers that serve as predictors for treatment response. To test this patients presenting for treatment of carpal tunnel syndrome will be monitored by ultrasound and by clinical assessment before and after non-surgical and surgical treatment. The clinical outcomes will be alined with the initial ultrasound motion patterns.
