Cameron KL, et al. - Via searching relevant electronic databases for randomized or quasi-randomized controlled trials, researchers tested the effectiveness of movement-based interventions to improve motor skills in preschool-age children with, or at risk of, motor impairment, including those with cerebral paralysis diagnosis, autism spectrum disorder, and developmental coordination disorder. Utilizing the Physiotherapy Evidence Database scale, the quality was assessed. In the preschool-age group, there is a lack of evidence examining movement-based interventions. Although movement-based interventions demonstrated the potential for improving body structure and function and activity outcomes for motor-impairment children, the findings were mostly not important. Small sample sizes, variable quality of the study, and risk of bias limit result confidence.
