Virtual reality integration with force feedback in upper limb rehabilitation

Abstract:

In this article, it presents an alternative rehabilitation system for upper extremity fine motor skills by using haptic devices implemented in a virtual reality interface. The proposed rehabilitation system develops 3D shapes and textures observed in virtual reality environments, interaction with environments generate specific rehabilitation exercises for conditions in patients to treat their conditions in the upper extremities; the system presents different rehabilitation environments focused on the use of virtual reality. The system is implemented through bilateral Unity3D software interaction with the Novint Falcon device further Oculus Rift and Leap motion is used for total immersion of the patient with the development of virtual reality. The patient performs a path, based in a rehabilitation entertainment brought about by the displacement and force feedback paths, which are based on physiotherapist’s exercises. Developed experimental results show the efficiency of the system, which generates the human interaction-machine, oriented to develop the human ability.
