Learning Performance Models For Post-Stroke Therapy From Demonstration


The use of robots and games is becoming a popular trend in stroke rehabilitation research. Despite the acknowledged importance, however, research on evaluating the patientís qualitative motor performance, customizing the initial task workspace based on the patientís performance, and generating visualized performance reports of autonomous sessions for the therapist have received little attention. The essence of these is to model the therapistís decision criteria to evaluate the qualitative motor performance and to use such evaluation to assess difficulties in the different regions of the task workspace for the individual stroke patient. In this talk, first I will motivate the needs of such models by introducing the results of a single-subject case study, and then propose a computational framework to learn the necessary models from therapist's demonstration. The experiment results with two patients and two therapists suggest that the proposed framework is promising.
