ABSTRACT
OBJECTIVE:
To assess the feasibility of Wii.n.Walk for improving walking capacity in older adults with lower limb amputation.DESIGN:
A parallel, evaluator-blind randomized controlled feasibility trial.SETTING:
Community-living.PARTICIPANTS:
Individuals who were ⩾50 years old with a unilateral lower limb amputation. INTERVENTION Wii.n.Walk 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. MAINMEASURES:
Feasibility indicators trial process (recruitment, retention, participants' perceived benefit from the Wii.n.Walk intervention measured by exit questionnaire), resources (adherence), management (participant processing, blinding), and treatment (adverse event, and Cohen's d effect size and variance). Primary clinicaloutcome:
walking capacity measured using the 2 Minute Walk Test at baseline, end of treatment, and 3-week retention.RESULTS:
Of 28 randomized participants, 24 completed the trial (12/arm). Median (range) age was 62.0 (50-78) years. Mean (SD) score for perceived benefit from the Wii.n.Walk intervention was 38.9/45 (6.8). Adherence was 83.4%. The effect sizes for the 2 Minute Walk Test were 0.5 (end of treatment) and 0.6 (3-week retention) based on intention to treat with imputed data; and 0.9 (end of treatment) and 1.2 (3-week retention) based on per protocol analysis. The required sample size for a future larger RCT was deemed to be 72 (36 per arm).CONCLUSIONS:
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.Palavras-chave
