Combined Approach to Treatment for Children with Hemiplegia (CATCH) is an organized approach of therapeutic interventions for children diagnosed with hemiplegia. Preliminary results from an evaluative study suggest that a play-based CATCH camp has a large effect on bilateral manual dexterity.

PURPOSE: CATCH targets functional participation, postural symmetry, and manual dexterity for children with hemiplegia by blending principles from constraint-induced movement therapy (CIMT), bilateral intensive training (BIT), and neuro-developmental treatment (NDT). Literature highlights intervention and effects on the more-affected upper extremity (UE) but has not fully explored the impact on the less-affected UE or the use of a combined approach.
PURPOSE: to evaluate the effectiveness of a play-based CATCH-camp on manual dexterity for more- and less-affected UE. Hypothesis: CATCH-camp will positively influence manual dexterity for the more-affected UE and have minimal effect on less-affected UE.
DESIGN: This evaluative study included a play-based CATCH-camp cohort with pre- and post-testing. Camp application inclusion criteria: age 4-10 years, physician diagnosis of hemiplegia, and ability to ambulate without a device or assistance.
METHOD: CATCH-camp elements: 1) six days (6.5 hr/day) of structured play-based tasks emphasizing postural alignment (NDT), 2) CIMT 5.5hrs/day [day 1-3] then 4 hrs/day [day 4-6], 3) BIT remainder of day. Box & Blocks testing (BBT) was completed with campers for less- followed by more-affected UE at OT evaluation for CATCH-camp (∼30 days prior) and the last day of CATCH-camp. We calculated the effect size of CATCH-camp on more- and less-affected UE using a paired Cohen’s-d (pre- and post-camp BBT).
RESULTS: The camp cohort (N=21, 6 females, 7.0±1.8 years) completed BBT pre- and post-camp. Overall, CATCH-camp resulted in a large effect on manual dexterity for both less-affected UE (d=0.81) and more-affected UE (d=1.045). Preliminary findings suggest improved dexterity bilaterally following a play-based CATCH-camp.
CONCLUSION: This proposal impacts OT practice and research as it supplies evidence for the value of 1) a combined intervention approach and 2) play-based interventions for improving performance for more- and less-affected UE.
