“…A Socially Assistive Robot (SAR) can be integrated into the rehabilitation process to provide motivation and support through social interaction for at-home or self-directed in-clinic rehabilitation exercises between visits to an occupational or physical therapist. In order to provide this type of support with a SAR, a greater understanding of how to motivate a patient is needed, since in the majority of rehabilitation paradigms (e.g., constraint induced movement therapy), it is a critical element of the intervention [2], [3]. Self-efficacy, a person's perception of their own competence at a task, is related to motivation, is thought to mediate motor performance, and may underlie many facets of post-stroke outcomes, including lower extremity performance, balance, and health outcomes [4], [5], [6], as well as upper-extremity limb choice [7], [8].…”
