Seven articles (247 children) were included in the review, of which six were randomised (one used cluster randomisation, three randomised matched-pairs) and one was quasi-randomised. These studies scored between 3 and 7 points on the PEDro quality scale; four were rated 'good', two were rated 'fair' and one was rated 'poor'.
All seven articles reported a significant improvement in function for the impaired arm for both constraint-induced movement therapy and bimanual training, of which five concluded that improvements in arm function and overall functional performance were similar for both therapies. One study reported greater improvement in grasp functions for constraint-induced movement therapy, but greater improvement in bilateral spontaneous use of the affected limb for bimanual training. Another study reported greater improvement in bimanual coordination in daily activities for bimanual training compared to constraint-induced movement therapy.
