Can Wii Fit improve walking in older adults with lower limb amputation?

This randomized controlled trial assessed the feasibility of an intervention called “Wii.n.Walk” for improving walking capacity in older adults with lower limb amputation.

The study’s participants included individuals who were ⩾50 years old with a unilateral lower limb amputation and who lived in a community-living setting. The “Wii.n.Walk” intervention consisted of Wii Fit training, 3x/week (40 minute sessions), for 4 weeks. Training started in the clinic in groups of 3 and graduated to unsupervised home training. Control group were trained using cognitive games.

The feasibility indicators measured included: trial process, resources, management, and treatment. The primary clinical outcome was as follows: walking capacity measured using the 2 Minute Walk Test at baseline, end of treatment, and 3-week retention.

The results suggested the feasibility of the Wii.n.Walk with a medium effect size for improving walking capacity. Future larger randomized controlled trials investigating efficacy are warranted.
