Effects of equine assisted activities on autism spectrum disorder

A Scoping Review of Equine-Assisted Therapies on the Mental Health and Well-Being of Autistic Children and Adolescents: Exploring the Possibilities

Animals are increasingly being utilized to assist with therapies for people with various health conditions. Horses are often used as a mechanism of engagement and development for autistic children and adolescents. Horses offer a unique opportunity for interaction as the child or adolescent can physically ride and interact with the animal, thus creating a therapy that involves contact that is different to other animals. Benefits derived from equine-assisted therapies can be physical, social, behavioral, emotional, sensory, and cognitive. However, a current and specific research gap exists in understanding the potential mental health impacts of horse riding on autistic children and adolescents, as perceived and experienced by their parents, carers, and horse-riding service providers. This scoping review examined research on parents' and service providers' perceptions of the benefits of horse-related therapies, with a particular focus on perceptions of positive mental health impacts. A comprehensive electronic search across PubMed, Scopus and Cumulative Index to Nursing and Allied Health Literature identified 16 articles from 15 studies which met the inclusion criteria. Findings included non-mental health-related benefits (as perceived by parents and service providers), mental health-related benefits (as perceived by parents and service providers), benefits for those other than the child/adolescent, and limitations of equine-assisted therapies. With the increased use of equine therapy, and the mounting evidence of its positive impacts on mental health, it is timely to expand research on how to better harness interventions and maximize the mental health benefits for autistic children and adolescents.

Equine-assisted therapy in quality of life and functioning of people with active epilepsy: A feasibility study

People with active epilepsy, which is often associated with specific neurological conditions, endure significant impairments in quality of life (QoL) and functioning, particularly those in middle-income countries. Physical intervention plays an essential role in addressing these challenges. This study investigated the impact of equine-assisted therapy (EAT) on QoL, functional independence, sleep quality, antiseizure medications, and frequency of seizures among people with epilepsy (PWE), with or without additional neurological conditions. Fourteen participants aged 4-34 years old diagnosed with focal epilepsy participated in a structured EAT program. The EAT program consisted of 36 sessions, each lasting 30 min and conducted weekly. Data were collected at four different times: baseline (T1), after 12 sessions (T2), after 24 sessions (T3), and after 36 sessions (T4). The assessments included the Quality of Life in Epilepsy (QOLIE-31), Functional Independence Measure (FIM), Pittsburgh Sleep Quality Index (PSQI), and Liverpool Adverse Event Profile (LAEP) scores. Seizure frequency was monitored continuously. Horse welfare was evaluated using the Horse Welfare Assessment Protocol (HWAP). After the EAT intervention, significant improvements were observed in the QoL scores (from 62.18 [57.88 - 70.25] to 80.18 [65.30 - 86.78]) and in FIM values (from 70.00 [36.50 - 97.75] to 70.00 [51.75 - 116.75]), particularly in the self-care and social cognition domains. Additionally, there was also a decrease in seizure frequency, adverse effects of antiseizure medications, and sleep quality. The HWAP indicated satisfactory welfare conditions for the horses. These findings indicate that EAT holds promise as a therapeutic intervention for improving the QoL and functioning of PWE. Tailored interventions are essential to address the diverse challenges faced by PWE, emphasizing the need for further research on effective therapeutic approaches.

Effectiveness of animal-assisted activities and therapies for autism spectrum disorder: a systematic review and meta-analysis

Background

Given the rising interest in complementary therapeutic strategies for autism spectrum disorder (ASD), this research aims to provide a comprehensive analysis of the impact of animal-assisted activities and therapies (AAAT) on various ASD symptoms.

Methods

A meticulous search of databases, including Scopus and PubMed, was conducted to gather relevant research on AAAT for ASD. This process led to the selection of 45 studies encompassing 1,212 participants. The chosen studies were then subjected to a meta-analysis to evaluate the efficacy of AAAT in alleviating core ASD symptoms.

Results

The meta-analysis revealed significant improvements in several core ASD symptoms due to AAAT. Notably, there were improvements in social communication (MD = -4.96, 95% CI [-7.49, -2.44]), irritability (MD = -2.38, 95% CI [-4.06, -0.71]), hyperactivity (MD = -4.03, 95% CI [-6.17, -1.89]), and different word usage skills (MD = 20.48, 95% CI [7.41, 33.55]). However, social awareness (MD = -1.63, 95% CI [-4.07, 0.81]), social cognition (MD = -3.60, 95% CI [-9.36, 2.17]), social mannerisms (MD = -0.73, 95% CI [-2.55, 1.09]), social motivation (MD = -1.21, 95% CI [-2.56, 0.13]), lethargy (MD = -1.12, 95% CI [-3.92, 1.68]), and stereotypical behaviors (MD = -0.23, 95% CI [-1.27, 0.80]) did not significantly improve.

Conclusion

The study demonstrates the potential of AAAT in improving certain core symptoms of ASD, such as social communication, irritability, hyperactivity, and word usage skills. However, the effectiveness of AAAT in other ASD symptom domains remains uncertain. The research is limited by the absence of long-term follow-up data and a high risk of bias in existing studies. Therefore, while the findings indicate the promise of AAAT in specific areas, caution is advised in generalizing its efficacy across all ASD symptoms.

Equine-assisted services for motor outcomes of autistic children: A systematic review

LAY ABSTRACT

Equine-assisted services use various aspects of horses, like their movement, warmth, and size, to enhance individuals' overall well-being. Many studies have underscored the positive impact of equine-assisted services on autistic children, affecting areas such as social interaction, communication, engagement, stereotypical behaviors, and motor functions. Given the growing recognition of motor functions as clinical specifiers in autism, it is imperative to specifically investigate how equine-assisted services influence these outcomes. To address this, we conducted a systematic review to synthesize existing literature on the effects of equine-assisted services on motor outcomes of autistic children. Our review encompassed study characteristics, features of equine-assisted service interventions, and major motor outcomes. We also evaluated the methodological quality of the equine-assisted service studies to offer insights for future research directions. Through thorough database searches and the use of the standardized procedure of conducting a systematic review (The Preferred Reporting Items for Systematic Reviews and Meta-analyses), 12 research studies were identified and included. These studies reported the effects of various equine-assisted service types (such as therapy, horsemanship, or learning) on motor outcomes of autistic children. Significant enhancements in coordination, strength, balance, posture, and overall motor skills indicate the effectiveness of equine-assisted services in improving motor outcomes of autistic children. Building on these findings, we provide recommendations for future research endeavors aimed at enhancing the reliability and validity of using equine-assisted services to improve motor outcomes of autistic children. This work contributes to a deeper understanding of how equine-assisted services can benefit this population and guides the development of more effective equine-assisted service interventions.

Autistic sociality: challenging representations of autism and human-animal interactions

PURPOSE

The objective of this synthesis research was to explore representations of autism and human-animal interactions (HAI) in the health sciences literature and the implications for autistic children and their families.

METHODS

Guided by critical interpretive synthesis methods proposed by Dixon-Woods et al. (2006), we synthesized and examined how autism and HAI were described in the health sciences literature and explored assumptions and goals underlying HAI as an intervention.

RESULTS

Across 47 reviewed articles, animals were represented as therapeutic objects whose purpose from a biomedical perspective was to address "problematic" behaviours and "deficits" in social functioning and development. HAI was employed as a therapy to address improvements in these problematic behaviours in the majority of studies. Relational and social aspects of HAI were present but not explicitly discussed. An alternative perspective proposed by Olga Solomon positioned autistic sociality as one form of diverse human socialities that can be embraced, rather than held problematic and in need of being normalized.

CONCLUSIONS

Implications for HAI in rehabilitation include recognizing the multiple purposes of animals in a child's life, not only the therapeutic goal of normalizing functioning.

Nature-Based Interventions for Autistic Children: A Systematic Review and Meta-Analysis

Importance

There is a gap in the evidence regarding nature-based interventions (NBIs) for children with autism spectrum disorder (ASD).

Objective

To systematically review and meta-analyze available evidence on the health-related outcomes in NBIs for children with ASD.

Data Sources

The Cumulative Index to Nursing and Allied Health Literature, Cochrane, Embase, Emcare, Education Resources Information Center, Global Health, MEDLINE, PsycInfo, SPORTDiscus, and Web of Science were searched from inception until May 2023. Google Scholar and references from included studies were searched for additional studies.

Study Selection

Included studies were randomized clinical trials (RCTs), controlled studies, and single-group before-and-after studies that reported health-related outcomes.

Data Extraction and Synthesis

This review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guidelines. Random-effects meta-analyses were used to synthesize the data. The findings of studies that were ineligible for meta-analysis were summarized according to the Synthesis Without Meta-analysis (SWIM) reporting guidelines.

Main Outcomes and Measures

The outcomes of interest were health-related outcomes (ie, social functioning, behavioral functioning, emotional functioning, sensory functioning) and the self-reported well-being of children with ASD.

Results

A total of 24 studies with 717 participants (mean age range, 5.3 to 17.8 years; 141 [21.9%] female) were included. A meta-analysis from 13 studies indicated a significant negative moderate association between NBIs and social communication (standardized mean difference [SMD], -0.59; 95% CI, -0.85 to -0.34). For behavioral functioning outcomes, NBIs showed a significant moderate association with reduced hyperactivity (SMD, -0.56; 95% CI, -0.86 to -0.26) and a small to moderate association with reduced irritability (SMD, -0.49; 95% CI, -0.79 to -0.19). For sensory functioning, NBIs were significantly associated with improved inattention and distractibility (SMD, 1.13; 95% CI, 0.67 to 1.60). Significant moderate associations were observed in sensory seeking (SMD, 0.77; 95% CI, 0.33 to 1.22; P < .001; I2 = 0%) and sensory sensitivity (SMD, 0.56; 95% CI, 0.12 to 1.00; P = .01; I2 = 0%). Heterogeneity of the intervention effects was not high, and I2 ranged from 0% to 67%.

Conclusions and Relevance

The findings of this systematic review and meta-analysis suggested an association of NBIs in group-based recreational therapy with experiential learning with positive short-term outcomes on sensory, social, and behavioral functioning for children with ASD. Future evidence using robust study design to aid the health and functional trajectories of children with ASD is recommended.

Animal-assisted therapies for autism

Animal-assisted therapies have been increasingly used as part of treatment for a range of emotional-behavioral conditions and have more recently been incorporated into treatment for children with symptoms associated with autism spectrum disorder. Autism spectrum disorder affects one in 36 children and early interventions can be very effective. The aims of this paper are to: 1) provide background into animal-assisted therapies including a breakdown on the subtypes of therapies, 2) report broad summaries of research outcomes across various domains: social-emotional, physical, quality of life, behavioral skills, and adaptive skills, and 3) summarize key takeaways for pediatric practitioners when supporting families of youth with autism spectrum disorder who are interested in participating in animal-assisted therapy. This paper is not a systematic review or meta-analysis as several rigorous review studies have been published already. This paper is an overview of the background and research for pediatric practitioners when advising families on treatment options. Implications for future research are covered.

Equine-Assisted Therapy in Post-Traumatic-Stress Disorder: A Systematic Review and Meta-Analysis

Alternative treatments for Post-traumatic-Stress Disorder (PTSD) have attracted attention, especially Equine-Assisted Services (EAS) including psychotherapy and occupational therapy involving horses. In this work, we measured the effectiveness of EAS in PTSD through a meta-analysis. An intensive bibliography search focusing in EAS and PTSD was conducted following the PRISMA recommendations. The search was not restricted by date. For the quantitative analyses, 5 works were selected. They were chosen based on the instrument utilized for the assessment of PTSD symptoms: the PTSD Checklist for DSM-5 (PCL-5). A random effects model was carried out, showing significant results in the reduction of PTSD symptoms. In the qualitative synthesis, 10 studies were included which showed interesting results in the improvement of PTSD symptoms and other variables. In conclusion, EAS are beneficial for post-traumatic symptoms in the short term follow-up period. However, EAS require further research and major standardization.

Equids in Equine Assisted Services: A Scoping Review

Equid welfare in equine assisted services (EAS) is an area that has received attention, but less attention than the documentation of human outcomes in response to EAS. To safeguard the well-being of equids and minimize human risk of injury, continued research on the effects of EAS programming and participants on equids needs to occur. The aims of this systematic scoping review were to identify the approaches taken for describing and understanding equids in EAS and the methods employed in evaluating equids' responses to EAS programming, participants, or both. Literature searches were performed in relevant databases to identify titles and abstracts for screening. Fifty-three articles were identified for full-text review. Fifty-one articles met the inclusion criteria and were retained for information and data extraction. The qualitative grouping of articles by study aim resulted in four categories: 1) characterization and description of equids in EAS; 2) the acute responses of equids to EAS programming, participants, or both; 3) the effects of management practices; and 4) the chronic responses of equids to EAS programming and participants. The latter three areas are in need of more research, especially as it relates to differentiating acute and chronic effects of EAS on the equids involved. Detailed reporting of information on study design, programming and participant characteristics, equid demographics, and workload are needed to facilitate comparison among studies and permit eventual meta-analysis of studies. Multi-faceted approaches including an array of measurements as well as relevant and informative control groups or conditions are required to identify the complex effects of EAS work on equids, their welfare, well-being, and affective states.

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

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.

Dancing out for a voice; a narrative review of the literature exploring autism, physical activity, and dance

Autism Spectrum Disorder is characterised by profound challenges with social communication and social interaction. Currently, there are few therapeutic interventions that successfully target some of the functionally impairing traits associated with autism. Furthermore, many of these interventions comprise a variety of limitations; including, limited accessibility, extensive durations, or the requirement of a trained professional to deliver the intervention. New research suggests that instead of targeting all traits associated with Autism Spectrum Disorder with a single solution, scientific research should focus on providing therapeutic tools that alleviate functionally impairing facets specific to the individual. Owing to the nature of physical activity, sports, and dance (coordinated movement) these activities could provide opportunities to enhance communication skills and social development in autistic children. Therefore, this paper gives a narrative overview of the literature surrounding communication and coordinated movement; outlining what is meant by communication challenges, exploring the benefits of coordinated movement for traits associated with Autism Spectrum Disorder, and delineating how coordinated movement elicits positive outcomes for autistic children.

Effects of Therapeutic Horseback-Riding Program on Social and Communication Skills in Children with Autism Spectrum Disorder: A Systematic Review and Meta-Analysis

Animal-assisted therapy has become a fast-growing and effective approach for remediating core impairments of children with ASD; however, recent systematic review studies on the effects of AAT in children with ASD have some limitations, including referral to a variety of animal-assisted interventions rather than to horseback-riding therapy alone and the absence of any meta-analysis in systematic reviews. A complete systematic review of the studies that describe the use of THR as an intervention is needed to specifically target the core impairments of children with ASD. The purpose of this study was to employ the systematic review method to synthesize research findings regarding the effects of THR programs on the social interaction and communication skills of children with ASD. We conducted a structured search in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched for potentially relevant studies in five databases (Web of Science, PubMed, CINAHL, Scopus, and SPORTDiscus) from inception until February 2022. In addition, we manually searched the bibliographies of the included studies to find articles that might otherwise have been missed. We considered articles eligible or ineligible if they satisfied specific inclusion or exclusion criteria. Our results showed that the THR program is an effective direct and alternative therapeutic program that can considerably improve the social behaviors and communication skills of children with ASD and can effectively impact autistic impairments in areas such as social awareness, social cognition, social motivation, and social communication. These findings are in line with those of previous studies; however, we did not find statistical evidence of any effect of THR on the autistic behaviors of irritability, stereotypy, and inappropriate speech. In conclusion, the findings produced by this meta-analysis study provide evidence that THR programs can considerably improve the social behaviors and communication skills of children with ASD.

Experiences of equine assisted therapy for females with autism spectrum disorders

Purpose

This research indicates females with autism spectrum disorders (ASDs) have a diverse clinical presentation compared to males. Furthermore, females with ASD are often diagnosed later and typically experience greater levels of mental health difficulties. Evidence suggests that clinic-based verbal interventions for ASD have limited efficacy; therefore, alternative therapies, such as equine-assisted therapies (EATs), are gaining recognition. The purpose of this study was to directly explore the experiences of females with an ASD who have undertaken EAT.

Design/methodology/approach

Five female participants with a diagnosis of ASD were recruited from two equine therapy centres. Participants were aged between 15 and 30 years and undertook semi-structured interviews, which were analysed using interpretative phenomenological analysis.

Findings

Three superordinate themes emerged: the difficult experience of the social world, the process of EAT and the emotional impact of horses.

Originality/value

Directly exploring the experiences of females with ASD highlights benefits from engaging therapeutically with horses, building confidence and independence to transferring this into more effective social communication with other people. Offering emotion-focused therapeutic complementary interventions for females with ASD should be forefronted to help remediate the impact of difficult and sometimes traumatic earlier experiences in the social world. This requires increased funding for EAT, combined with larger-scale research projects to evaluate this.

Specific and Non-specific Factors of Animal-Assisted Interventions Considered in Research: A Systematic Review

Research on animal-assisted interventions (AAIs) has increased massively in the last few years. But it is still not clear how AAIs work and how important the animal is in such interventions. The aim of this systematic review was to compile the existing state of knowledge about the working mechanisms of AAIs. We searched 12 major electronic databases for previous AAI studies with active control groups. Of 2001 records identified, we included 172 studies in the systematic review. We extracted previously published hypotheses about working mechanisms and factors that have been implicitly considered specific or non-specific in AAI research by categorizing control conditions using content analysis. We analyzed the categories using descriptive statistics. We found that 84% of the included studies mentioned a hypothesis of working mechanisms, but 16% did not define specific hypotheses. By analyzing their control conditions, we found that in most controlled studies, the animal or the interaction with the animal was implicitly considered as a specific factor for the effects of the AAI. Non-specific factors such as therapeutic aspects, social interactions, or novelty have also been controlled for. We conclude that AAI research still cannot answer the question of how and why AAIs work. To address this important research gap, we suggest using component studies with innovative control conditions and results from placebo research to address both the specific and non-specific, contextual factors of AAIs to disentangle its mechanisms.

Therapeutic Riding or Mindfulness: Comparative Effectiveness of Two Recreational Therapy Interventions for Adolescents with Autism

Therapeutic riding (THR) and HeartMath (HM) mindfulness-based interventions have promise for reducing stress in adolescents with autism spectrum disorder. In three 10-week periods, this study compared THR, HM, and control on salivary cortisol, self-reported stress, parent-reported social responsiveness, and heart-rate variability. This crossover design included 27 participants (12-21 years) randomly assigned to order of intervention. Findings suggest that HM and THR manualized protocols are equally beneficial in decreasing cortisol levels immediately following a session, but HM sessions had more impact on heart-rate variability. There was no significant effect on follow-up cortisol levels within a week after either intervention, but THR had more impact on decreasing some self-reported stressors.

Terapias y actividades asistidas con animales para niños con TEA: un estudio de revisión

Este trabajo incluye una revisión de la literatura publicada entre 2010 y 2019 que aborda la efectividad de las Terapias y Actividades Asistidas con Animales como intervención con niños y adolescentes con Trastorno del Espectro Autista (TEA). Se realizó una búsqueda bibliográfica en PsycINFO, PsycARTICLES, ProQuest, ERIC y Google Scholar, empleando los términos [(animal assisted therapy OR animal assisted intervention OR dog-assisted therapy OR equine-assisted therapy OR dolphin-assisted therapy) AND (autism OR ASD)]. Se identificaron 245 estudios, de los cuales se seleccionaron 40 con base en diferentes criterios de inclusión, tales como que las intervenciones descritas tengan un enfoque psicoeducativo y sean evaluadas mediante instrumentos rigurosos. En cada uno de ellos se revisaron las variables analizadas, los instrumentos de evaluación utilizados, las características de cada intervención y los resultados obtenidos. Los resultados sugieren que los animales más utilizados son el caballo y el perro, y que este tipo de intervención tiene efectos positivos para niños con TEA en áreas como la interacción y la comunicación social, el comportamiento y el desarrollo motor, entre otros. Se concluye que es una intervención beneficiosa para niños y adolescentes con autismo, aunque siempre como complemento de otro tipo de tratamientos.

Equine-Assisted Interventions (EAIs) for Children with Autism Spectrum Disorders (ASD): Behavioural and Physiological Indices of Stress in Domestic Horses (Equus caballus) during Riding Sessions

Equine-assisted interventions (EAIs) are well-known complementary practices combining physical activity with emotional/cognitive stimulation. They are especially suited for children with autism spectrum disorders (ASD) who need a high degree of physical and psychological enrichment. Even though EAIs have become a common practice, stress responses in horses interacting with individuals that can manifest inappropriate behaviours, such as ASD children, have not been thoroughly investigated. Our multicentre study aimed to investigate behavioural and physiological indices of stress in horses involved in EAI standardised sessions with children with ASD compared to typically developing (TD) children. A controlled within-subject design with repeated measurements involving 19 horses and 38 children was adopted. Stress-related behaviours, heart rate, heart rate variability, and eye temperature were recorded during the riding sessions. Moreover, blood samples were collected from horses before and after each session to monitor changes in blood adrenocorticotropic hormone (ACTH), cortisol, and catecholamines. Results indicate that, in general, stress responses in horses involved in EAIs did not differ as a function of the horse being ridden by children with ASD or TD. A lower sympathetic tone in horses involved in ASD sessions was found, while in the mounting and dismounting phases, horses displayed behavioural signs of stress, independently from children's behaviour. We conclude that professionals working in EAI should increase their awareness of animal welfare and refine riding practices, taking into account horse's needs.

Effectiveness of Equine-Assisted Activities and Therapies for Improving Adaptive Behavior and Motor Function in Autism Spectrum Disorder

Equine-assisted activities and therapies (EAAT) have been suggested to improve adaptive behavior, and possibly motor function, in autism spectrum disorder (ASD). This study investigated the effects of EAAT on adaptive behavior and motor function in 15 children with ASD (13 males) aged 7–15 years as well as the impact of EAAT on the magnitude of stress in the parent–child system and the evolution in the child interaction with both the trained therapist and the therapeutic animal through the 20 weekly sessions of EAAT. EAAT were associated with greater adaptive behavior and coordination (all p ≤ 0.01) as well as a progressive improvement in the child’s abilities to respond to the increasing complexity of such form of positive behavioral support (all p < 0.001). However, EAAT did not prove to be effective in reducing parental distress. Collectively, preliminary evidence presented here may have important public health implications and gives reason to hope that EAAT could possibly be an effective option in ASD, warranting further investigation of its potential benefits in clinical trials among larger samples.

Hippotherapy in neurodevelopmental disorders: a narrative review focusing on cognitive and behavioral outcomes

Hippotherapy (HT) is a rehabilitative tool inducing psychological and motor improvements using human-horse interaction. HT provides sensory stimulation to the rider through the rhythmic and repetitive movements of the horse, facilitating communication between patients and healthcare professionals, favoring the establishment of a therapeutic alliance. The purpose of this review is to evaluate the effects of HT treatment on cognitive-behavioral processes in neurodevelopmental disorders. We screened studies published between 2002 and 2020 on PubMed, Scopus, Cochrane, and Web of Sciences databases. The search combined the following terms: "hippotherapy"; "horseback riding"; "equine-assisted therapy"; "developmental disorder"; "autism spectrum disorder"; "dyspraxia"; "infantile cerebral palsy"; and "attention-deficit/hyperactivity disorder". This review shows that HT can be a valuable tool for the treatment of developmental disorders. The psychological, cognitive and relational areas could benefit from the animal-child interaction to promote child autonomy, self-esteem, self-efficacy and openness to others. Physical, motor and psychosocial benefits were found in adolescents with anxiety and/or depression disorders, in autism spectrum disorders, dyspraxia, as well as in infantile cerebral palsy and attention deficit hyperactivity disorder. HT could be considered an alternative therapeutic tool thanks to the relationship between patient-horse-instructor and to the sensory-motor and cognitive stimulation that enforce learning processes.

Exploring Human-Companion Animal Interaction in Families of Children with Autism

The study goal was to explore companion animal (CA) ownership in families of children with autism spectrum disorder (ASD), including parents' beliefs about benefits and burdens of CAs, as well as parent stress. Participants (N = 764) completed online survey instruments anonymously. Findings revealed that parents with lower incomes perceived more benefits of CAs and their children were more strongly bonded with their CAs. Parents owning both a dog and cat perceived more benefits than those with only a dog or cat. Dog owners perceived more benefits than cat owners. Parents who perceived their CAs as providing more benefits had less stress. Provider implications are to consider recommending CAs to families of children with ASD for family benefits including lower parental stress.

Animal-Assisted Interventions for School-Aged Children with Autism Spectrum Disorder: A Meta-Analysis

Research has indicated beneficial effects of Animal-Assisted Interventions (AAIs) for children with Autism. However, there is a dearth of meta-analyses and findings are often contradictory. The current meta-analysis assesses the effectiveness of AAIs on social interaction, communication and global Autism symptoms. A total of 1447 studies were returned, of which 16 (n = 489) met the inclusion criteria. The meta-analyses indicated small effect sizes related to improvements in social interaction and communication and reduction in Autism Spectrum Disorder symptoms. Additionally, there was little evidence for a relationship between dosage and effect size. In conclusion, AAIs appear to offer small improvements in social interaction and communication for children with Autism, which may be comparable to activities used in active control conditions.

Parental Perception of Changes in Basic Life Needs of Children with Disabilities after Six Months of Therapeutic Horseback Riding: A Qualitative Study

Therapeutic horseback riding (THR) has a positive effect on the physical, cognitive, and psychosocial functioning of children with disabilities. Parents’ reports of the effects of THR on their children support professionals in individualizing the THR program. With this qualitative study, we aimed to explore parents’ perceptions of changes in the basic life needs of their children with disabilities after six months of THR lessons and to survey parents’ explanations for the causes of these changes. The study involved parents of 13 children with disabilities who were enrolled in a six-month THR program. Parents continuously monitored their children and wrote a report on possible changes in their child’s needs according to Virginia Henderson’s need theory. Qualitative content analysis of parents’ reports indicated only positive changes in 11 children. Most codes were identified in categories “relationships and communication with other people” and “movement and posturing”. Other categories identified codes such as easier breathing, a better quality of sleep, better appetite, better elimination of stool and urine, more independence in clothing and maintaining personal hygiene, and greater interest in play and learning. Parents’ reports are further supported by the assessments of professionals. Most parents think THR is responsible for the noticeable improvements in their children’s quality of life.

Autism spectrum disorder: psychological and functional assessment, and behavioral treatment approaches

There have been significant changes in the way Autism has been defined especially in the last decade. The changes encompass criteria over a spectrum rather than individual diagnoses based on clusters of criteria. With these changes, there has been a push for earlier screening and diagnosis to be made to ensure individual impacted by the deficits have ample time and opportunity to receive the services they need. Additionally, with the changes that have come up, screening tools and assessments have also been changed and improved to assist with the increasing demand of early screening. Screeners have been created to help in primary care settings so physicians can gauge the severity of symptoms and refer patients to the appropriate resources. The assessment and diagnostic process for Autism involves a large battery including parental interviews and forms, the ADOS-II, and a multitude of other intellectual assessments to get a full picture of what the individual is experiencing. Once an individual is diagnosed with Autism, the interventionist team, physicians, and clinicians assist the family in finding the appropriate resources and treatment plan. There are several evidence-based therapies that exist that have been effective in improving the quality of life of individuals with Autism Spectrum Disorder diagnoses. Although several interventions and therapies exist, there are some potential interventions some use that need to more research to know how truly effective they are.

The effect of motor and physical activity intervention on motor outcomes of children with autism spectrum disorder: A systematic review

Difficulty performing age-appropriate motor skills affects up to 83% of children with autism spectrum disorder. This systematic review examined the effect of motor and physical activity intervention on motor outcomes of children with autism spectrum disorder and the effect of motor learning strategies on motor skill acquisition, retention, and transfer. Six databases were searched from 2000 to 2019. Forty-one studies were included: 34 intervention studies and 7 motor learning studies. The overall quality of the evidence was low. Participants included 1173 children with autism spectrum disorder ranging from 3 to 19 years. Results from level II and III intervention studies supported that participation outcomes improved with a physical education intervention; activity outcomes improved with aquatic, motor activity, motor skill, and simulated horse riding interventions; and body structure and function outcomes improved with aquatic, exergaming, motor activity, motor skill, and simulated horse riding interventions. Results from level II and III motor learning studies supported that motor skill acquisition improved with visual, versus verbal, instructions but was not influenced by differences in instructional personnel. More rigorous research on motor intervention is needed with well-controlled study designs, adequate sample sizes, and manualized protocols. In addition, research on motor learning strategies is warranted as it generalizes across motor interventions.

Evaluating Animal-Assisted Interventions: An Empirical Illustration of Differences between Outcome Measures

Simple Summary

This study compares and contrasts several outcome measures to assess the effect of an equine-assisted intervention for a child with Autism Spectrum Disorder. Before and after the equine-assisted sessions, we conducted a semi-structured interview with the participant’s parents, asked parents to fill out a general screening instrument separately, and observed the participant’s social and communication skills during five equine-assisted sessions. We found differences between the interview and questionnaire with regard to parents’ perceptions of aggression regulation and interacting with peers. Differences with regard to parental reports and observations were found for play development and anxiety. The observations provided a detailed view of the child’s development during the intervention, which yielded an interesting hypothesis in terms of the current dose–response discussion in AAI for children with Autism Spectrum Disorder.

Abstract

Multiple authors have called for strong empirical evaluations to strengthen the foundation of Animal-Assisted Interventions. Carefully choosing the outcome measures of these studies is important, as choosing the wrong outcomes may lead to a failure to detect effects. The current study therefore compares and contrasts the use of several outcome measures, to assess the effect of an equine-assisted intervention for a child with Autism Spectrum Disorder: (1) a semi-structured interview with both parents, specifically designed for children with cognitive disabilities, (2) a general screening instrument filled out by both parents separately, which can be used to assess children’s psycho-social problems, and (3) systematic observations of social and communication skills during the equine-assisted sessions. All instruments indicated an improvement in the participant’s social and communication skills. We found differences between the interview and questionnaires with regard to parents’ perception of aggression regulation and interacting with peers. Differences with regard to parental reports and observations were found for play development and anxiety. The observations provided a detailed view of the child’s development during the intervention, which yielded an interesting hypothesis in terms of the current dose–response discussion in AAI for children with Autism Spectrum Disorder.

Animal assisted therapy: systematic review of literature

PURPOSE

to verify the applications of AAT in health by performing a systematic review of the literature.

RESEARCH STRATEGY

a survey was carried out in four databases with the descriptors: animal assisted therapy, horse assisted therapy, speech therapy.

SELECTION CRITERIA

article published between 2010 and 2018, in Portuguese or English, free electronic access and that mentioned the characteristics of the intervention program.

DATA ANALYSIS

criteria: casuistry, area of knowledge, program characteristic, type of research, year and language of publication, nationality, periodical and impact factor.

RESULTS

43 articles published in 30 journals, 16 with impact factor, were reviewed. Clinical studies prevailed (93.02%), 37.20% were from Medicine, the population studied had different diagnoses and ages, 55.81% with adults / elderly. AAT was used preferentially for physical rehabilitation (67.44%) and the main mediator was the dog, mentioned in 72.09% of the articles. Eight (n = 8) programs with a focus on communication intervention were described.

CONCLUSION

There is scientific evidence on the use of AAT published in the period studied, in Brazil and in the world. The programs were used by different health and education professionals. The AAT goals were specific to the profile of the participants, and consistent with the characteristics of the mediator animal and the site.

Parent Perceptions of Psychosocial Outcomes of Equine-Assisted Interventions for Children with Autism Spectrum Disorder

This research explored parents' perceptions of the psychosocial outcomes of their children's experience of receiving equine-assisted interventions (EAI). Participants were the parents of six children (aged 3-14) diagnosed with autism spectrum disorder. Five semi-structured interviews were conducted and the transcript data was analysed using Interpretative phenomenological analysis. Four super-ordinate themes emerged from the analysis: (1) child's improved self-concept and enhanced emotional well-being, (2) child's improved self-regulatory ability, (3) social benefits for the child, and (4) unexpected outcomes. EAI was perceived by the parents as having several levels of psychosocial benefits for their children. These benefits may also extend to parents and family through ecopsychological and "flow on" effects associated with the children's involvement in EAI programs.

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

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.

Effectiveness of Animal-Assisted Therapy in the Pediatric Population: Systematic Review and Meta-Analysis of Controlled Studies

OBJECTIVE

To synthesize the results of controlled studies evaluating the effectiveness of animal-assisted therapy (AAT) in children.

METHODS

Eleven databases were searched following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement recommendations, and references from included studies and previous reviews were examined. No date or language filters were applied. Only controlled study designs, including those using wait-list controls, that studied a specific condition or illness were included. Study quality was assessed using the Cochrane Risk of Bias Tool.

RESULTS

Twenty-six studies that met the inclusion criteria were retrieved. Nine were conducted in children with autism spectrum disorders, 10 in cerebral palsy (CP), 2 in Down syndrome, 3 in pain, and 2 in other conditions. Qualitative synthesis showed a small but significant contribution of AAT to the management of these conditions. Meta-analysis showed a mean difference in improvement in the Gross Motor Function Measure-66 scale in children with CP of 1.61 (95% confidence interval [CI] -2.00 to 5.23) and a mean difference for 5-point pain scales of -0.81 (95% CI -1.32 to 0.30), both favoring AAT.

CONCLUSION

Animal-assisted therapy may be useful as a complementary intervention in the management of children with CP and pain. Although results are in general positive for the management of children with Down syndrome and autism, the diversity of scales used to measure outcomes makes it difficult to establish true effectiveness. The application of simple corrective measures in the randomization process would greatly improve the quality of evidence. It is necessary to reach a consensus between AAT researchers regarding appropriate instruments to provide higher-quality evidence in further studies.

Effects of Equine Therapy on Individuals with Autism Spectrum Disorder: A Systematic Review

Literature on effects of equine therapy in individuals with autism spectrum disorder (ASD) has grown in recent times. Equine therapy is an alternative multimodal intervention that involves utilizing a horse to enhance core impairments in ASD. Recent systematic reviews in this area have several limitations including inclusion of populations other than ASD, assessment of a variety of animal-assisted interventions other than equine therapy, and a failure to conduct quantitative analyses to provide accurate effect size estimates. We conducted a focused systematic review to address these limitations. Our review suggested that equine therapy has beneficial effects on behavioral skills and to some extent on social communication in ASD. The evidence for positive effects of equine therapy on perceptuo-motor, cognitive, and functional skills is currently limited.

The Impact of a Horse Riding Intervention on the Social Functioning of Children with Autism Spectrum Disorder

This paper reports a case-control study of a horse riding intervention for children with autism spectrum disorder (ASD). A sample of 26 children, aged 6 to 9 years, were assigned to either the intervention (n = 12) or control group conditions (n = 14). Pre- and post-tests were carried out using the Childhood Autism Rating Scale, Second Edition (CARS2) and the Aberrant Behaviour Checklist-Community Edition (ABC-C). An observational measure of compliance and behaviour during the horse riding sessions was completed for the intervention group. There was a significant reduction in the severity of ASD symptoms and hyperactivity from pre- to post-test for the intervention group only. These results indicate that the intervention improves some aspects of social functioning for children with ASD.

'It just opens up their world': autism, empathy, and the therapeutic effects of equine interactions

Experiences of autism-spectrum disorder are now increasingly studied by social scientists. Human–animal relations have also become a major focus of social inquiry in recent years. Examining horse-assisted therapy for autistic spectrum disorders, this is the first paper that brings these fields together. Drawing on participant observation and interviews at a UK horse therapy Centre, this article examines how staff and the parents of riders account for the successes and limitations of equine therapy. To the respondents, horses ‘open up’ autistic children and make possible interactions that seemed impossible before. Horses were regarded as facilitating the emergence of apparently social behaviours, which included eye contact, pointing, and speech. Three key explanations emerged for therapeutic success: the sensorial, embodied experience of riding the horse; the specific movements and rhythms of the horse; and, the ‘personality’ of the horse. Equine therapy can be regarded as enabling a form of multispecies intersubjectivity, with the resonance between rider and horse seeming to make possible a new attunement between humans. Practices of equine therapy, and perceptions of its efficacy, serve in turn to attune social scientists to a version of empathy constituted through lively and sensorial interactions, as opposed to one that is restricted to particular kinds of humans.

Green Care: A Review of the Benefits and Potential of Animal-Assisted Care Farming Globally and in Rural America

Simple Summary

The term Green Care encompasses a number of therapeutic strategies that can include farm-animal-assisted therapy, horticultural therapy, and general, farm-based therapy. This review article provides an overview of how Green Care has been used as part of the therapeutic plan for a variety of psychological disorders and related physical disabilities in children, adolescents and adults. While many countries have embraced Green Care, and research-based evidence supports its efficacy in a variety of therapeutic models, it has not yet gained widespread popularity in the United States. We suggest that Green Care could prove to be an effective approach to providing mental health care in the U.S., particularly in rural areas that are typically underserved by more traditional mental health facilities, but have an abundance of farms, livestock, and green spaces where care might be effectively provided.

Abstract

The term Green Care includes therapeutic, social or educational interventions involving farming; farm animals; gardening or general contact with nature. Although Green Care can occur in any setting in which there is interaction with plants or animals, this review focuses on therapeutic practices occurring on farms. The efficacy of care farming is discussed and the broad utilization of care farming and farm care communities in Europe is reviewed. Though evidence from care farms in the United States is included in this review, the empirical evidence which could determine its efficacy is lacking. For example, the empirical evidence supporting or refuting the efficacy of therapeutic horseback riding in adults is minimal, while there is little non-equine care farming literature with children. The health care systems in Europe are also much different than those in the United States. In order for insurance companies to cover Green Care techniques in the United States, extensive research is necessary. This paper proposes community-based ways that Green Care methods can be utilized without insurance in the United States. Though Green Care can certainly be provided in urban areas, this paper focuses on ways rural areas can utilize existing farms to benefit the mental and physical health of their communities.

Research on animal-assisted intervention and autism spectrum disorder, 2012-2015

Including animals in autism intervention is growing in both research and practice. A systematic literature review was conducted to collate and synthesize all empirical research on animal-assisted intervention (AAI) for autism published from 2012 to 2015. Findings from 28 included studies revealed that AAI programs generally include one animal per participant with a total contact time of approximately 10 hours over the course of 8 to 12 weeks. Research methodology is diverse and though limited in many cases, has improved over the last few years. The most commonly reported outcome was increased social interaction, which was unanimously significant across 22 studies. The need for further research is highlighted, calling for a focus on refining AAI techniques, identifying optimal circumstances for positive change as well as individuals who may not benefit, and independent replication of high quality studies to move AAI from an enrichment activity to an evidence-based practice for autism.

Effectiveness of a Standardized Equine-Assisted Therapy Program for Children with Autism Spectrum Disorder

In this study the effectiveness of an equine-assisted therapy (EAT) in improving adaptive and executive functioning in children with autism spectrum disorder (ASD) was examined (children attending EAT, n = 15, control group n = 13; inclusion criteria: IQ > 70). Therapeutic sessions consisted in structured activities involving horses and included both work on the ground and riding. Results indicate an improvement in social functioning in the group attending EAT (compared to the control group) and a milder effect on motor abilities. Improved executive functioning was also observed (i.e. reduced planning time in a problem-solving task) at the end of the EAT program. Our findings provide further support for the use of animal-assisted intervention programs as complementary intervention strategies for children with ASD.

Evidence for Using Farm Care Practices to Improve Attachment Outcomes in Foster Children: A Systematic Review

Anecdotal evidence suggests that care farming practices have the potential to provide positive outcomes for young people in foster-care and residential care environments. A systematic review (searching; CINAHL, Web of Knowledge, PsychInfo) was conducted to explore how participation in care farming initiatives impacts attachment in children in foster-care and what aspects of care farming initiatives provides positive attachment outcomes. The systematic review did not identify any research publication in care farming and foster-care. Therefore, it is imperative that practitioners realise that the evidence is lacking when using these types of interventions and keep a close account of the benefit and harms that may be encountered during the interaction processes.

Hippotherapy acute impact on heart rate variability non-linear dynamics in neurological disorders

Neurological disorders are associated with autonomic dysfunction. Hippotherapy (HT) is a therapy treatment strategy that utilizes a horse in an interdisciplinary approach for the physical and mental rehabilitation of people with physical, mental and/or psychological disabilities. However, no studies have been carried out which evaluated the effects of HT on the autonomic control in these patients. Therefore, the objective of the present study was to investigate the effects of a single HT session on cardiovascular autonomic control by time domain and non-linear analysis of heart rate variability (HRV). The HRV signal was recorded continuously in twelve children affected by neurological disorders during a HT session, consisting in a 10-minute sitting position rest (P1), a 15-minute preparatory phase sitting on the horse (P2), a 15-minute HT session (P3) and a final 10-minute sitting position recovery (P4). Time domain and non-linear HRV indices, including Sample Entropy (SampEn), Lempel-Ziv Complexity (LZC) and Detrended Fluctuation Analysis (DFA), were calculated for each treatment phase. We observed that SampEn increased during P3 (SampEn=0.56±0.10) with respect to P1 (SampEn=0.40±0.14, p<0.05), while DFA decreased during P3 (DFA=1.10±0.10) with respect to P1 (DFA=1.26±0.14, p<0.05). A significant SDRR increase (p<0.05) was observed during the recovery period P4 (SDRR=50±30ms) with respect to the HT session period P3 (SDRR=30±10ms). Our results suggest that HT might benefit children with disabilities attributable to neurological disorders by eliciting an acute autonomic response during the therapy and during the recovery period.

What Factors Are Associated with Positive Effects of Dog Ownership in Families with Children with Autism Spectrum Disorder? The Development of the Lincoln Autism Pet Dog Impact Scale

Scientific literature exploring the value of assistance dogs to children with autism spectrum disorder (ASD) is rapidly emerging. However, there is comparably less literature reporting the effects of pet (as opposed to assistance) dogs to these children. In particular, there are no known validated scales which assess how children may alter their behaviours in the presence of the dog, to evaluate the efficacy of pet dogs to these families. Additionally, given the highly individualised nature of ASD it is likely that some children and families gain more benefits from dog ownership than others, yet no research has reported the effect of individual differences. This pilot study reports the development of a 28-item scale based on the perceived impact of a pet dog on a child with autism by parents (Lincoln Autism Pet Dog Impact Scale--LAPDIS). The scale is comprised of three mathematically derived factors: Adaptability, Social Skills and Conflict Management. We assessed how individual differences (aspects) may be associated with scores on these three factors. Family Aspects and Dog Aspects were not significantly associated with ratings on the three factors, but Child Aspects (including: contact with horses, child age, disability level and language abilities) were related to impact of the dog on all factors. Training Aspects were related to scores on Social Skills (formal training with children with ASD and dogs and attendance at PAWS workshops run by Dogs for Good). These results suggest that individual differences associated with the child and the training approach may be important considerations for a positive impact from dog ownership on families with children with ASD. Differences in family features and the dog may not be so important, but may be worthy of further investigations given the early stage of development in this field.

Animal-Assisted Therapies for Youth with or at risk for Mental Health Problems: A Systematic Review

To systematically review experimental evidence about animal-assisted therapies (AAT) for children or adolescents with or at risk for mental health conditions, we reviewed all experimental AAT studies published between 2000-2015, and compared studies by animal type, intervention, and outcomes.

METHODS

Studies were included if used therapeutically for children and adolescents (≤21 years) with or at risk for a mental health problem; used random assignment or a waitlist comparison/control group; and included child-specific outcome data. Of 1,535 studies, 24 met inclusion criteria.

RESULTS

Of 24 studies identified, almost half were randomized controlled trials, with 9 of 11 published in the past two years. The largest group addresses equine therapies for autism.

CONCLUSION

Findings are generally promising for positive effects associated with equine therapies for autism and canine therapies for childhood trauma. The AAT research base is slim; a more focused research agenda is outlined.
