We propose to develop and evaluate a workstation that significantly enhances the application of CI therapy by automating and instrumenting several of the tasks currently used in the shaping training. The motivation for development of such a device is as follows: 1) Patients could receive CI therapy at home without the need for constant supervision from a therapist. Many veterans do not have the resources to travel to their local VAMC for the two or three week period required for the treatment. A home-based device would expand the pool of veterans who could receive CI therapy. 2) For subjects who were able to receive CI therapy in the clinic, this device would facilitate an effective post-treatment home-practice program. 3) Currently, patients are treated on a one-on-one basis in the clinic. This device could allow one therapist to treat 3 or 4 patients at one time, thereby substantially reducing the cost of the therapy. 4) This workstation would provide clear and comprehensive quantification of the progress of the treatment. This could indicate on which tasks the patient was progressing most and least rapidly, and would therefore enable effective modifications of the treatment plan while treatment was in progress.
