RehaBall: Rehabilitation of upper limbs with a sensory-integrated stress ball

This paper presents the development of a virtual reality game and a special electronic tangible user interface that can be applied to the hand rehabilitation procedure. RehaBall consists of a VR car racing game and an oval-shaped stress ball integrated with sensors and actuators, and aim to help people with wrist injuries to perform their daily rehabilitation training from the comfort of their homes. The system can be configured to fit the rehabilitation needs of different patients by allowing them to choose the desired range of motion they would like to achieve. The training sensory data are stored in a database that could be used later on by a therapist to track the patient´s progress.
