Abstract
AIM: To evaluate the feasibility and effectiveness of an action observation treatment (AOT) home-based platform promoting child-to-child interaction to improve hand motor function in unilateral cerebral palsy (CP). METHOD: Twenty children (14 males, six females; mean age 6y 7mo, standard deviation 1y 7mo; range 5y 1mo-10y 6mo) with unilateral CP underwent 20 sessions where they had to observe and then imitate a wizard performing dexterity-demanding magic tricks; a child-to-child live video-session to practise the same exercise then took place. We assessed hand-motor skills with the Besta Scale, neurological motor impairment with Fugl-Meyer Assessment for upper extremity, as well as spasticity, muscle strength, visual analogue scale, and global impression of change 1-month before (T-1), at baseline (T0), and at the end of treatment (T1). RESULTS: We observed a T0 to T1 improvement in global hand-motor and bimanual skills, and a significant correlation between motor improvement and difference in hand motor skills relative to the peer (r=-0.519). INTERPRETATION: AOT associated with child-to-child interaction effectively improves hand motor function in unilateral CP. This improvement is linked to differences in hand motor ability among peers, suggesting that children should observe others with superior motor skills to their own. This study extends traditional AOT toward novel socially-enriched scenarios, where children might simultaneously be recipients and leaders within a motor learning process. WHAT THIS PAPER ADDS: Home-based action observation treatment (AOT) based on child-to-child interaction improves hand motor function in children with unilateral cerebral palsy. Interaction with a more capable peer increases the chances of positive outcome in child-to-child AOT.
