Balance and mobility training at home using Wii Fit in children with cerebral palsy: a feasibility study

Objectives To investigate whether balance and mobility training at home using Wii Fit is feasible and can provide clinical benefits. Design Single-group, pre–post intervention study. Setting Participants’ home. Participants 20 children with cerebral palsy (6–12？years). Intervention Participants undertook 8 weeks of home-based Wii Fit training in addition to usual care. Main measures Feasibility was determined by adherence, performance, acceptability and safety. Clinical outcomes were strength, balance, mobility and participation measured at baseline (preintervention) and 8 weeks (postintervention). Results The training was feasible with 99% of training completed; performance on all games improved; parents understood the training (4/5), it did not interfere in life (3.8/5), was challenging (3.9/5) and would recommend it (3.9/5); and there were no injurious falls. Strength increased in dorsiflexors (Mean Difference (MD) 2.2？N m, 95%？CI 1.1 to 3.2, p<0.001), plantarflexors (MD 2.2？N m, 95%？CI 1.3 to 3.1, p<0.001) and quadriceps (MD 7.8？N m, 95%？CI 5.2 to 10.5, p<0.001). Preferred walking speed increased (MD 0.25 m/s, 95%？CI 0.09 to 0.41, p<0.01), fast speed increased (MD 0.24 m/s, 95%？CI 0.13 to 0.35, p<0.001) and distance over 6？min increased (MD 28？m, 95%？CI 10 to 45, p<0.01). Independence in participation increased (MD 1.4 out of 40, 95%？CI 0.0 to 2.8, p=0.04). Conclusions Balance and mobility training at home using Wii Fit was feasible and safe and has the potential to improve strength and mobility, suggesting that a randomised trial is warranted.
