Summary

The diagnosis of carpal tunnel syndrome (CTS) is typically based on clinical findings and confirmatory electrodiagnostic testing. However, electrodiagnostic testing can only assess large A-alpha and A-beta nerve fibers. Quantitative sensory testing (QST) is a series of tests used to assess small nerve fiber changes in the A-delta, c-fibers, and A-beta nerve fibers as well. Previous studies have used QST to assess small nerve fiber changes related to carpal tunnel syndrome and found changes compared to controls. This study will utilize a course of standard physical therapy care and assess for any changes to small nerve fiber activity and how those changes may or may not relate to patient outcomes.

Detailed description

Purpose: To assess changes in A-beta, A-deta, and C-fiber function after standard physical therapy interventions in individuals with CTS. Specific Aim 1 (primary aim): Determine if A-beta, A-deta, and C-fiber functions change following a course of Physical Therapy (PT) in individuals with CTS. Specific Aim 2 (secondary aim): Describe the relationship between changes in QST and changes in a patient-reported outcome measure after a course of PT in individuals with a clinical diagnosis of CTS. Specific Aim 3 (secondary aim): Determine if there are differences in A-beta, A-deta, and C-fiber function between the affected and unaffected wrists in individuals with a clinical diagnosis of CTS.
