Reaching of the affected arm was faster (larger MT; F = 10.21, p &lt; 0.01), smoother (fewer MU; F = 19.95, p &lt; 0.001), and better-controlled (right shift of PPV; F = 16.03, p &lt; 0.001) compared with the semi and nonfunctional condition. Reaching of the nonaffected arm was also faster (longer MT, F = 4.81, p &lt; 0.05), and more smooth (fewer MU, F = 7.23, p &lt; 0.05). <\/jats:p><jats:p> Conclusions: These findings suggest that providing a functional context to perform a task may enhance the quality of reaching movements of the affected arm in children with spastic hemiparesis.
