Human-Robot Interaction for Children with Cerebral Palsy: Reflection and Suggestion for Interactive Scenario Design

This paper explains how a humanoid robot NAO can be used as an assistive technology in specific therapy for children with cerebral palsy (CP). The role of the robot is to motivate the children as to keep them engaged in therapy. To achieve this, the robot must have appropriate appearance to be able to establish affective engagement between child and robot. In addition, the robot should exhibit the right therapeutic approach of managing children with CP. How the humanoid robot NAO acts as a tool to assist in improving the outcome of conventional therapy especially by imitation learning will also be explained. Four interactive scenarios in human-robot interaction (HRI) were designed based on the measurement items in Gross Motor Functional Measure (GMFM). The scenarios will then be constructed based on suitability that will be executed by the robot. As a result from the discussions between clinicians, therapists and engineers, four interactive scenarios consists of introductory rapport, sit to stand, body balancing and ball kicking activity have been formulated. The study has been performed in collaboration between the Faculty of Medicine and the Faculty of Mechanical Engineering at the Medical Specialist Centre, Discipline of Rehabilitation Medicine, Faculty of Medicine, UiTM Sungai Buloh, Selangor, Malaysia.
