Diagnosis of Carpal Tunnel Syndrome: Effectiveness of Diagnostic Tests. Clinical Trial of Accuracy

There is no golden universal standard for the diagnosis of Carpal Tunnel Syndrome (CTS). In this scenario, for a comparison of the effectiveness of the principal diagnostic tests CTS should determine how they affect the likelihood of disease through a clinical accuracy trial of good methodological quality in order to get answers to what is the best diagnostic strategy in clinical CTS practice. The paresthesia in nerve distribution territory median hands is the most common symptom in patients with CTS. The nuisance caused by paresthesia directly affects the quality of life of patients and impairs daily manual activities and sleep quality. To evaluate the remission of paresthesia is a major clinical criterion for improved STC being an expected relevant outcome for the patient. This study evaluated and compared the diagnostic accuracy of the ultrasonography (US) and electromyography (EMG), considering the postoperative status of remission of paresthesia as the reference standard in the diagnosis of CTS.
