Effects of Equine-Assisted Activities and Therapies for Individuals with Autism Spectrum Disorder: Systematic Review and Meta-Analysis

Abstract

Autism spectrum disorder (ASD) has become a critical public health issue that affects more than 78 million people. In many recent studies, the authors have demonstrated that equine-assisted activities and therapies (EAATs) can substantially improve the social and behavioral skills of children with ASD. However, the qualities of the studies differ, and some authors reached opposite conclusions. In this review, we systematically and objectively examined the effectiveness of EAATs for people with ASD, combining both qualitative and quantitative methods. We searched five databases (PubMed, Scopus, ERIC, ProQuest, and MEDLINE) and added relevant references, and we identified 25 articles for data extraction and analysis. According to our results, EAAT programs can substantially improve the social and behavioral functioning and language abilities of children with ASD. However, among the subdomains, the results were inconsistent. According to the meta-analyses, there were considerable improvements in the social cognition, communication, irritability, and hyperactivity domains, but not in the domains of social awareness, mannerisms, motivation, lethargy, stereotypy, or inappropriate speech. Moreover, there was a lack of sufficient comparative data to conclude that EAAT programs lead to substantial improvements in motor and sensory functioning. In addition, among the included studies, we noted the indicator of whether EAAT programs decreased parental stress and improved family functioning, and although there were four articles in which the researchers considered this aspect, we were unable to draw any conclusions because of the insufficient data and conflicting descriptive evidence. However, we need to consider the improvement in parental mental health as a factor in the effectiveness of this complementary intervention. We hope that in future studies, researchers will focus on family functioning and conduct more randomized controlled trials (RCTs) with blinded assessments using different scales and measures.

Building up bit by bit, parent’s experiences of equine–assisted intervention among children and adolescents with mental illness: a grounded theory study

“…This study demonstrates quite positive outcomes for children and adolescents with mental ill health who took part in an EAS intervention. Our findings are in line with other EAS studies with participants who had autism spectrum disorders (Xiao et al, 2023 ), attention-deficit/hyperactivity disorder, or cerebral palsy (Ahn et al, 2021 ). Therefore, it could be argued that the findings are transferable to different contexts and children or adolescents with different health problems.…”

The safety and efficacy of oral antiviral drug VV116 for treatment of COVID-19: A systematic review

“…To thoroughly assess the quality of the included literature, we used the PEDro scale and the Cochrane Risk of Bias Table (ROB) to evaluate the quality and internal validity of the RCTs. [35] This scale consists of eleven scoring items, and as with the previously published articles, [36] a PEDro score of 6 to 10 is considered high quality, a score of 4 to 5 is considered moderate quality, and a score of 3 or less is deemed low quality. Additionally, for the included observational studies, we used the Sackett’s levels of evidence for evaluation.…”

Effects of Physical Activity on Cognition, Behavior, and Motor Skills in Youth with Autism Spectrum Disorder: A Systematic Review of Intervention Studies

“…The second approach is psychosocial treatments, incorporating video technology and telehealth during the last decade to coach parents [14]. Other studies indicate that alternative treatments, such as equine-assisted activities and therapies [15], social-behavioral interventions [16], and mindfulness programs [17], provide improvements such as greater social interaction, decreased problem behaviors, and improved inhibitory abilities, respectively.…”
