Effectiveness of perceptual-motor exercises and physical activity on the cognitive, motor, and academic skills of children with learning disorders: A systematic review.

Abstract

Children with specific learning disorders (SLD) may have issues in cognitive, motor, and academic skills, affecting their mental health and level of participation in academic and nonacademic activities at school and in everyday life. Research shows that perceptual-motor (PM) exercises and physical activities can improve the cognitive and motor skills of typically developing children. To use PM exercises as an intervention in clinical practice for children with learning disorders, or to use it in future research, it seems necessary to discuss and summarize the existing documents in this group of children. We aimed to appraise the extent, and the quality of studies about PM interventions for enhancing cognitive, motor, and academic skills in children with learning disorders. The search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles published between January 2000 and June 2022 were searched in the following scientific databases: PubMed, Medline, Scopus, Web of Science, Cochrane library, Science direct, and Google Scholar. The study eligibility criteria were previously established according to the PICOS model. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the studies, and the Cochrane Collaboration tool (ROB2) was used to assess the risk of bias. The initial search yielded 2160 studies among which 10 studies were systematically reviewed. The total number of participants was 483 children (intervention: 251; control: 232). Findings showed significant improvements in cognitive skills (n= 7/8) such as working memory, attention, and information processing speed. In addition, studies showed that PM and physical activity interventions could increase academic performance (n= 4/5) and motor skills (n= 5/5) in children with LD. Results regarding the mental health effects of PM exercises (n= 1/3) are few in number and contradicting. PM exercises may positively affect cognitive, motor, and academic skills in children with SLD; However, due to the small number of studies, fair methodological quality, and high risk of bias, caution should be taken when interpreting the results.
