Assessment of Carpal Tunnel Syndrome by Shearwave Elastography

The investigators will acquire at least 4 acquisitions for each of 2 locations on the wrist. The objective is to correlate SWE measurements with patient-reported measures of symptom severity and functional status scores and severity of pre-operative electrodiagnostic tests (EDX). Evaluate the treatment response to surgical decompression or corticosteroid injection, using quantitative SWE and correlate the results to repeated patient reported outcomes with Boston CTQ, and objective clinical improvement with Semmes-Weinstein monofilament evaluation for recovery of sensibility, and grip and lateral pinch strength.
