Virtual rehabilitation of upper-limb function in traumatic brain injury: A mixed-approach evaluation of the Elements system

Abstract

The aim of this study was to assess the efficacy of the Elements virtual reality (VR) system for rehabilitation of upper-limb function in patients with traumatic brain injury (TBI). A mixed-approach design was used. Performance was evaluated at three time points using a within-group design: Preintervention 1 and 2, conducted 4 weeks apart, and Postintervention. Subjective ratings were provided after patients completed exploratory tasks. The intervention consisted of 12 1-hour training sessions over 4 weeks in addition to conventional physical therapy. Nine patients aged 18-48 years with severe TBI were recruited. The Elements system is comprised of a 40-inch tabletop LCD, camera tracking sys..
