The METHODS for this multi-centered study include recruiting patients from multiple hand surgeons and neurologists and these patients will have been diagnosed with following the physicians' physical examination and a nerve conduction test of the median nerve. The subjects then will be briefed on this study and sign an informed consent as required by the IRB before participating. Subjects who do consent will then be given the Levine-Katz disability and pain scale test, and prior to being fit with the Carpal Tunnel Dynasplint® Subjects will be taught how to use a Carpal Tunnel Dynasplint® properly and after being fit with the Carpal Tunnel Dynasplint® each subject will be required to complete a weekly report showing compliance to the wearing and treatment schedule, and they must attend regular, monthly examinations by the referring physician. After the initial sixty (60) days in the study each subject will repeat the three lead conduction test of the median nerve.
