Objective: What are the possible clinical benefits of social robots in rehabilitation for children? This preliminary study explores the characteristics required of robots which interact with children in a post-surgery inpatient setting.

Process: In this setting, NAO robot was used to mimic exercises and motivate children when the therapist was not present. Children had two sessions weekly with a therapist, followed by a third session with NAO, over a period of five months. NAO speaks and demonstrates each exercise, provides a focus during the exercises to minimize boredom, provides encouraging and rewarding vocalizations and records the child’s activity for later review.

Findings: Outcomes of interest are specific to the characteristics of the device. Issues that detracted from NAO’s functionality were movement and speech slowness, physical stability and limited balance, voice clarity and battery life.

Objective: to survey therapists on the desired characteristics of gait-training robots.

Process: 100 physiatrists and 100 physical therapists from 38 hospitals were given questionnaires. One-third of the respondents had worked with a gait-training robot before, and a third had more than 5 years experience with stroke rehabilitation.

Results: therapists thought that treadmill type gait-training robots should be used with non-independent ambulators to "improve treatment effects" one to three months after stroke. Sensors should detect electromyography, foot pressure, joint torque, tilt sensor. Qualities of design and production should include: stability, comfort, easiness on-and-off, "fitting sense" and light weight.
