Any time that an Intensive Therapy model was studied, in comparison to a control group utilizing traditional therapy, the Intensive Therapy participants saw better results than their controlled peers. This
Journal of Child Neurology 2014 article summarizes 19 such studies, all of which showed strong evidence for intensive therapy improving function and plasticity. The therapy dose in the studies varied from 40 to 120 hours and was augmented by a home program.
Example of such studies are a
2007 Emory University School of Medicine study focused on children with hemiplegic CP, where those taking part in a 2-week intensive, accompanied by a month-long 1-2 hr/day daily home program, were compared to a control group. The treated children all saw improvements in 11 out of the 12 functions being tested, whereas the control group remained unchanged.
