Reaching accuracy and overall PFC activity (averaged across hemispheres) for time-constrained reaching. Results are presented for each arm (A and D), and for each time constraint during non-preferred arm (B and E) and preferred arm reaching (C and F). Values are mean ± SE; ¹group x arm interaction; ²group difference; ³arm difference; ⁴main effect of group; ⁵main effect of time constraint; ⁶time constraint difference; ⁷group x time constraint interaction; HbO oxyhemoglobin, CP Cerebral palsy, Con Typically developing controls, r_s Spearman rho
