BACKGROUND: Previous studies reported controversial results about the efficacy of video-game based therapy (VGT) in improving neurorehabilitation outcomes in children with cerebral palsy (CP). AIM: Primary aim was to investigate the effectiveness of VGT with respect to conventional therapy (CT) in improving upper limb motor outcomes in a group of children with CP. Secondary aim was to quantify if VGT leads children to perform a higher number of movements. DESIGN: A cross-over randomized controlled trial (RCT) for investigating the primary aim and a cross-sectional study for investigating the secondary aim of this study. SETTINGS: Outpatients. POPULATION: INCLUSION CRITERIA: Clinical diagnosis of CP, age between 4 and 14 years, level of GMFC between I and IV. EXCLUSION CRITERIA: QI < 35, severe comorbidities, incapacity to stand even with an external support. METHODS: Twenty-two children with CP (6.89 +/- 1.91-year old) were enrolled in a cross-over RCT with 16 sessions of VGT (using Xbox with Kinect device) and then 16 of CT or vice versa. Upper limb functioning was assessed using the Quality of Upper Extremities Skills Test (QUEST) and hand abilities using Abilhand-kids score. According to the secondary aim of this study a secondary cross-sectional study has been performed. Eight children with CP (6.50 +/- 1.60-year old) were enrolled into a trial in which five wireless triaxial accelerometers were positioned on their forearms, legs and trunk for quantifying the physical activity during VGT versus CT. RESULTS: QUEST scores significantly improved only after VGT (p = 0.003), and not after CT (p = 0.056). The reverse occurred for Abilhand-kids scores (p = 0.165 versus p = 0.013, respectively). Quantity of performed movements was three times higher in VGT than in CT (+198AJQ-, p = 0.027). CONCLUSION: VGT resulted effective in improving the motor functions of upper limb extremities in children with CP, conceivably for the increased quantity of limb movements, but failed in improving the manual abilities for performing activities of daily living which benefited more from CT.
