“…Moreover, sensorimotor enrichment was associated with improved Leiter International Performance Scale-Revised scores (a measure of objective nonverbal cognitive abilities), significant increases in IQ, Reynell receptive language scores, and improvements in sensory reactivity (Woo & Leon, 2013;Woo et al, 2015). Using similar forms of sensorimotor stimulation, there is now an emerging body of clinical work supporting the use of EE in young patients with Down syndrome, cerebral palsy, and Rett syndrome (Downs et al, 2018;Morgan, Novak, & Badawi, 2013;Morgan, Novak, Dale, & Badawi, 2015;Purpura et al, 2014). While there is some initial evidence that EE exposure changes the expression of IGF and BDNF in both humans and animals (Baldini et al, 2013;Downs et al, 2018;Field et al, 2008;Landi, Ciucci, Maffei, Berardi, & Cenni, 2009), the underlying mechanisms and necessary/sufficient components of the EE protocols that promote clinical benefit are not fully understood.…”
