Perceived Usefulness of a Social Robot Augmented Telehealth Platform by Therapists in the United States.

With the shortage of rehabilitation clinicians in rural areas and the ongoing COVID-19 pandemic, remote rehabilitation (telerehab) fills an important gap in access to rehabilitation, especially for the treatment of adults and children experiencing upper arm disability due to stroke and cerebral palsy. We propose the use of a socially assistive robot with arms, a torso, and a face to play games with and guide patients, coupled with a telepresence platform, to maintain the patient-clinician interaction, and a computer vision system, to aid in automated objective assessments, as a tool for achieving more effective telerehab. In this paper, we outline the design of such a system, Lil'Flo, and present a uniquely large perceived usefulness evaluation of the Lil'Flo platform with 351 practicing therapists in the United States. We analyzed responses to the question of general interest and 5 questions on Lil'Flo's perceived usefulness. Therapists believe that Lil'Flo would significantly improve communication, motivation, and compliance during telerehab interactions when compared to traditional telepresence. 27% of therapists reported that they were interested in using Lil'Flo. Therapists interested in using Lil'Flo perceived it as having significantly higher usefulness across all measured dimensions than those who were not interested in using it.
