Background: Dual-task (simultaneous motor and cognitive task) (DT) training via virtual-reality exergaming is known to benefit balance control post-stroke. However, the efficacy of such training on DT balance control (volitional and reactive) and cognitive (executive function and attention) domains associated with fall risk remains unclear.
Objective: We evaluated the efficacy of cognitive-motor exergame training (CMT) (Wii-fit games in conjunction with cognitive tasks) for improving balance control (volitional and reactive) and cognition (executive function and attention) among people with chronic stroke (PwCS).
Methods: Hemiparetic, ambulatory PwCS were randomly assigned to either CMT (n = 12) or conventional training (CT) (n = 12) and underwent six weeks of high-intensity, tapered balance training. The CMT group performed Wii-fit games in conjunction with cognitive tasks, while CT group underwent customized, progressive balance training. Performance under DT conditions on Limits of Stability (volitional) and Slip-Perturbation (reactive) tests, and letter-number sequencing (cognition) determined the efficacy of CMT.
Results: Post-intervention, under DT reactive conditions, CMT group improved both motor and cognition, while the CT group improved motor alone. Under DT volitional conditions, motor performance improved only in CMT group.
Conclusion: Cognitive-motor exergaming appears to be effective for improving balance control and cognition and could be implemented in clinical stroke rehabilitation settings.
