Equine assisted activities and therapies in children with autism spectrum disorder: A systematic review and a meta-analysis

Abstract

Introduction: The multifactorial nature of Autism Spectrum Disorder (ASD) is the reason why complementary and alternative methods of treatment are sought in order to support the classic approach.Objectives: The aim of the study was to assess the effectiveness of Equine-Assisted Activities and Therapies (EAAT) in ASD patients based on a review of the literature.Methods: A review of the literature and a meta-analysis were conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PUBMED, Cochrane Library, Web of Science, ClinicalTrials.gov and PEDro databases were searched until July 20, 2017. Only articles published in English, in a journal with a review process, after 1999, with a control group or presentation of comparative pre-/post-therapy results in ASD patients, and clear inclusion/exclusion criteria were considered. The methodological quality of the included studies was assessed using the Quality Assessment Tool for Quantitative Studies (QATQS).The meta-analysis of three studies was conducted.Results: A total of 15 studies with 390 participants (aged: 3–16 years) were included. The interaction between psychosocial functioning and EAAT was investigated in most studies. Improvement was reported in the following domains: socialization, engagement, maladaptive behaviors, and shorter reaction time in problem-solving situations after EAAT. The meta-analysis revealed no statistically significant differences for the investigated effects.Conclusions: Despite the need for further, more standardized research, the results of the studies included in this review allow us to conclude that EAAT may be a useful form of therapy in children with ASD.
