The hypothesis is that the positive outcomes of CI therapy can be achieved, and possibly enhanced, if the shaping training component is performed in a workstation that guides, motivates and records exercise of the more-affected limb. In the first 18 months, the workstation will be designed and fabricated. To expedite the design, we will rely on simple modifications to "off the shelf" components. In the last 18 months, a controlled, randomized, clinical trial will compare the effectiveness of automated CI therapy programs with standard CI therapy. The standard CI therapy group would receive shaping training in a clinical setting, one-on-one with a therapist. The clinic-based automated CI therapy group would perform the shaping training in the workstation, in a clinical setting and with minimal supervision. The home-based automated CI therapy group would perform the shaping training at home in the workstation, and with no direct supervision. All other aspects of the three treatment programs will be identical. At the end of this 3-year project, a device will have been designed, built and evaluated that could significantly enhance the application of CI therapy for chronic stroke patients.
