A virtual fine rehabilitation system for children with cerebral palsy: Assesment of the usability of a low-cost system

Abstract:

Children with Cerebral Palsy (CP) have difficulty performing correct movements for activities of daily living. Impairments in the first stages of the birth produce motor disorders of the neuromuscular system. Specific goals in traditional rehabilitation are based on the outcomes obtained in the Gross Motor Function Classification System (GMFCS) and are focused on the improvements of muscle strength and length. In the last few years, novel Virtual Environments have been designed to reduce impairments in upper limbs, but few studies have been validated with the use of specific usability tests that are focused on the rehabilitation process of children with CP. The purpose of this study is to analyze the usability, enjoyment, and security of a novel virtual system. To do this, we tested the System Usability Scale with a child that has CP during one session. The outcomes show that our system achieves the goals in terms of usability, enjoyment, and security.
