Treatment of Carpal Tunnel Syndrome With Dynamic Splinting

This study will compare the efficacy of treating Carpal tunnel Syndrome with the Dynasplint®
Systems device as compared to a non-treatment control group utilizing a randomized,
controlled, cross-over study design. The dependant variables in this study are each
patient's score on a Levine-Katz disability and pain scale test, and the change in nerve
conduction of the median nerve that was tested upon diagnosis. The independent variables
will include three different patient groups separated by randomization. The first group of
subjects (selected randomly) will be fit with a therapeutic, functional Carpal Tunnel
Dynasplint® versus the second, control patients will not be treated with dynamic splinting
for the first sixty (60) days. After the initial sixty (60) days, the original control
patients will be fit with a functional Carpal Tunnel Dynasplint® system and this will allow
examiner to evaluate for further variance between subject groups, allowing the third group
to be a Cross-Over group.

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.

Control subjects at this point will be fit with the Carpal Tunnel Dynasplint® systems
becoming Cross-Over subjects and their final nerve conduction test will be administered
after they have worn the Carpal Tunnel Dynasplint® system for sixty (60) days. Upon
discharge from this study all subjects will also retake the Levine-Katz disability and pain
scale test.

Eighty (80) SUBJECTS will be recruited following diagnosis of CTS (using nerve conduction
testing of the median nerve for differential diagnosis) and group assignment will be
determined through randomization following each patient's completion of the informed consent
required by the IRB. All patients randomly selected to start in the experimental group will
be fit with functional Carpal Tunnel Dynasplint® and the control group subjects will not be
fit until after sixty (60) days. When they are ultimately fit, they will then be categorized
as "Cross-Over" subjects to measure continued variance between all groups.

The DURATION for patients enrolled in this study will be sixty (60) days for the
experimental subjects and the control subjects will spend their first sixty (60) days as a
control role without treatment. However, following sixty days the initial control subjects
but then they will be refit with a functional Carpal Tunnel Dynasplint® as a "Cross-Over"
subject for an additional sixty (60) days, which makes the control subjects duration in this
study 120 days.
