| Abstract: | Objective: Hemiplegic cerebral palsy often results in impaired bimanual coordination, partly due to strong coupling between the arms. We aimed at inducing more flexibility in this coupling, to improve bimanual coordination.Methods: We designed computer games involving simple perceptual goals, based on Lissajous feedback. Such feedback implicitly facilitates the performance of complex rhythmic bimanual coordination patterns. A sample of six children received 9?h of computer training over a 6 weeks period. The effects of this training on functional bimanual performance were explored using the Assisting Hand Assessment (AHA).Results: Gaming performance and bimanual rhythmic antiphase coordination improved after training. The AHA results were mixed. Two children improved significantly, but at a group level no significant effects were found.Conclusions: The results were evaluated in relation to the specificity of the AHA and the potential benefit of combining the proposed training with dedicated bimanual functional training programs. |
