 Participants in both groups will perform VRT for 30-50 minutes daily for 10-12 sessions, in addition to their rehabilitation program. VRT will be delivered with Jintronix software and motion capture technology. Exercises for the experimental group will challenge sitting balance control, reaching and shifting the base of support. Control group exercises will require limited hand and arm movements, to equalize the additional time spent in an engaging activity without working on trunk balance. Control group participants will be strapped into their chair to minimize trunk movement. A CONFORMat pressure mat will be used to monitor centre of pressure changes during the intervention.
