About this study

The Carpal Tunnel Syndrome Diagnosis and Treatment Trial is project #1 of the Multidisciplinary Clinical Research Center focused on upper extremity pain. It is a randomized trial comparing surgical and nonsurgical treatments for patients with early, mild to moderate carpal tunnel syndrome. In addition the study will evaluate the ability of a new magnetic resonance (MR) technique at predicting who will likely benefit from carpal tunnel syndrome (CTS) surgery.

Read the detailed description

While there is good evidence that patients with severe CTS benefit from surgery, there is less evidence of a benefit for patients with mild to moderate disease. However, mild to moderate disease still accounts for important disability. Electrodiagnostic studies (EDS) have not been shown to accurately predict outcomes for patients with CTS. Recent advances in MR permit high-resolution neurographic imaging of the median nerve, and pilot data suggest that wrist MRI might be a better predictor of outcome than EDS. Thus, wrist MRI has the potential for playing a major role in the treatment of patients with CTS. We will test two main hypotheses: 1) that select patients with early, mild or moderate CTS benefit more from early surgery than with conservative therapy; and, 2) that wrist MRI accurately identifies those patients more likely to benefit from surgery. We will perform a randomized, controlled treatment trial nested within a prospective cohort as our study design.

What does the primary outcome measure?

Carpal Tunnel Syndrome Assessment Questionnaire- function scale (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00032227, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
