BioTrak: a comprehensive overview

This paper describes the BioTrak system, a balance rehabilitation system that uses virtual reality technology to immerse patients in a virtual environment where they are challenged to fulfill simple tasks by means of their own movements. The system tries to motivate and involve patients in order to improve their adherence to the treatment, their effort and, thus, their recovery. This manuscript presents an overview of the system and an early validation. Thirteen patients with acquired brain injury participated in 15 sessions with the system and show significant improvement in Berg Balance Scale, Tinetti Gait Assessment, and balance control in medial-lateral and anterior-posterior plane, quantified with a posturography study.
