Motor learning in children with hemiplegic cerebral palsy: feedback effects on skill acquisition
PA Burtner, R Leinwand, KJ Sullivan, H-T Goh, SS Kantak

As occupational/physical therapists, we investigated how children with hemiplegic cerebral palsy (CP) learn new motor skills.
  • Do they learn best with constant or occasional feedback?
  • Is learning similar to peers without CP?
Twenty children with CP and 19 children without CP practised a computer-based motor task using their preferred hand. Half of the children in each group received feedback on their accuracy after each trial (100%) and the other half received reduced feedback (62%). Learning was measured by their accuracy the next day (retention).
Children with CP used feedback similarly, but demonstrated less accuracy and consistency than children without CP. All children receiving 100% feedback demonstrated greater learning. When learning new motor skills with their less-involved hand, children with CP may benefit from 100% feedback and more practice trials.
We need more information about how different feedback levels affect learning in children with right versus left hemiplegia of varying ages.
