The effects of video game therapy on balance and attention in chronic ambulatory traumatic brain injury: an exploratory study

BACKGROUND Patients with traumatic brain injury often have balance and attentive disorders. Video game therapy (VGT) has been proposed as a new intervention to improve mobility and attention through a reward-learning approach. In this pilot randomized, controlled trial, we tested the effects of VGT, compared with a balance platform therapy (BPT), on balance, mobility and selective attention in chronic traumatic brain injury patients. METHODS We enrolled chronic traumatic brain injury patients (n = 21) that randomly received VGT or BPT for 3 sessions per week for 6 weeks. The clinical outcome measures included: i) the Community Balance & Mobility Scale (CB&M); ii) the Unified Balance Scale (UBS); iii) the Timed Up and Go test (TUG); iv) static balance and v) selective visual attention evaluation (Go/Nogo task). RESULTS Both groups improved in CB&M scores, but only the VGT group increased on the UBS and TUG with a between-group significance (p < 0.05). Selective attention improved significantly in the VGT group (p < 0.01). CONCLUSIONS Video game therapy is an option for the management of chronic traumatic brain injury patients to ameliorate balance and attention deficits. TRIAL REGISTRATION NCT01883830 , April 5 2013.
