Human-animal interaction with regards to horses encompasses the various ways in which humans and horses engage and communicate with each other. This field of study examines the behavioral, psychological, and physiological responses that occur during these interactions. Researchers investigate aspects such as the impact of human presence on horse behavior, the effects of different training methods, and the mutual benefits of human-horse relationships. Studies often focus on how these interactions influence equine welfare, training outcomes, and human psychological well-being. This page compiles peer-reviewed research studies and scholarly articles that explore the dynamics, outcomes, and implications of human-animal interactions involving horses.
Bargigli G, Frassineti L, Baragli P, Scopa C, Vignoli A, Lanata A.This review examines the evidence in the literature for physiological co-modulation during human-animal interaction, identifying studies that assessed comodulation via simultaneous measurement of physiological signals in both species, performing quantitative comparisons. We searched (last search: August 5, 2025) PubMed, EMBASE, Scopus, Google Scholar, Animal Studies Repository, Cochrane, and the Consensus App academic search engine. Risk of bias was assessed using an adapted version of the ROBINS-I V2 tool. The results, grouped by data analysis method, interaction context, and physiological pa...
Hamm PJ.This essay offers a psycho-spiritual and psychoanalytic meditation on the horse-human relationship as a nonverbal site of attunement, regulation, and meaning-making. Drawing on autobiographical clinical narrative, it explores how horseback riding became a medium for experiencing and reflecting upon embodied connection, mutual responsiveness, and contemplative presence. Encounters with horses illuminate forms of reciprocity that preceded and exceed speech, while also opening reflection on maternal attachment, separation, loss, and the emergence of selfhood. In dialogue with Freud, Winnicott, Pi...
Cerqueira de Melo Vasco AC, Brooks S, White-Springer SH, Hammer CJ, Bruemmer JE, Yoho T, Jacobs R.The equine industry represents a complex and evolving sector with substantial economic, social, and scientific significance, yet it faces growing challenges related to funding constraints, societal expectations for animal welfare, regulatory pressures, and rapid scientific and technological change. This article synthesizes perspectives presented at the 2025 Horse Species Symposium, held during the joint Annual Meeting of the American Society of Animal Science and Canadian Society of Animal Science, which convened experts from academia, government, and industry to evaluate the current state and...
Luke KL, Hockenhull J, Furtado T, Ainley N, Osborne M.To improve horse welfare do we need more science or a different scientific approach? For over 40 years researchers have called for change to improve horse welfare. During this time, publications have grown exponentially, improving our understanding of horse's needs and the need for change. However, the translation of science into practice is arguably too slow, and yet, there is scant industry-specific research to guide change efforts. To assist behaviour change research, this paper recasts an influential, highly regarded systems thinking framework, the Meadows 12, for the horse industry as the...
Dransmann M, Koddebusch M, Wicker P, Gröben D, Gröben B.Equine-assisted programs have been shown to promote psychosocial outcomes, but quantitative evidence of motor benefits in correctional settings is scarce. Objective: The present study examined the effects of a one-week equine-assisted riding program on riding performance, movement quality, and well-being among young inmates in an open German prison. Methods: Ten male participants (24.5 ± 0.71 years) completed a five-day program combining practical riding exercises, cooperative activities, and guided reflection. Riding performance was assessed using standardized expert video ratings based on t...
Louis AT, Treesa Louis A, Mikkola A.Effective rider-horse coordination is essential for performance and welfare, yet objective, field-based quantification of rider-saddle synchronization across gaits remains limited. Objective: To quantify dynamic synchronization between rider motion and saddle motion (as a proxy for horse trunk oscillations) across walk, trot, and canter using a minimal inertial measurement unit (IMU) setup, and to determine whether synchronization differs between rider body segments. Methods: Two experienced riders (8-20 years riding experience) rode their own or familiar warmblood horses (n = 2; age 6-14 year...
Anthony D, Trautmann M, Heyd V.Recent papers argued that the domestication of horses can be equated with the appearance of favorable genetic mutations that are first evident in individuals in the DOM2 clade dated about ∼2200-2100 BCE. We challenge the idea that this genetic shift alone defines domestication. Evidence from archaeology, ancient DNA, osteology, and other disciplines shows that horses from multiple genetic backgrounds (DOM1, DOM2, and, as we suggest here, DOM3) were managed, milked, and ridden long before 2200 BCE. Yamnaya groups (∼3200-2600 BCE) rode DOM2 horses-the direct ancestors of modern domestic stoc...
Gholami BB, Fatahi A, Boroushak N, Molavian R.Aging is characterized by a decline in functional abilities, strength, balance, flexibility, agility, and coordination due to neurological and muscular changes. Hippotherapy (HPOT) has been recognized for its physical and psychological benefits for older adults. Hence, this study aimed to investigate the effects of hippotherapy on balance in elderly individuals. The novelty lies in using the Biodex Balance System SD for dynamic balance assessment in healthy elderly without neurological disorders. Unassigned: We recruited elderly men aged 60 to 70 who had independent mobility and medical cleara...
Shani P, Espinosa L, Banerjee A, Butt SA, Hernandez H.Nurse burnout poses a significant risk to workforce stability. This study investigated the impact of equine-assisted learning (EAL) on secondary traumatic stress, job burnout, subjective distress, and resiliency among nurses. Background: Effective interventions for early detection and management of stress and burnout are essential for workforce stability. Methods: Using a pre-post-interventional design, this study evaluated the impact of EAL on psychosocial well-being. Outcomes were measured using self-reported questionnaires at baseline, postintervention, and 1-month follow-up. Linear mixed m...
Lungren L, Mazzarella J, Mumbauer-Pisano J.This qualitative study explored healthcare students' lived experiences during an interprofessional education (IPE) event incorporating equine-assisted services (EAS). Traditional IPE events often rely on classroom settings that may limit interprofessional engagement, collaboration, and application. Utilizing interpretive phenomenological analysis, researchers examined how the equine environment influenced interprofessional learning among fourteen graduate students from diverse healthcare disciplines at a western United States public university. Participants engaged in experiential demonstratio...
Goodale L.Giving animals the opportunity to exercise agency can improve their welfare, but horse owners and researchers may not be aware of the growing body of agency research in other animals, and studies on agency and choice in horses are scattered across disciplines and not connected to each other or to broader theory. This paper summarises research findings on management of domestic horses through the lens of animal agency and explores the potential applications of research on choice, control, and challenge in animals to improve the welfare of horses.
Arora S, Kieson E, Rudd C, Gloor PA.Automated recognition of equine-human interaction behaviors from video represents a significant challenge in computational ethology, with critical applications spanning animal welfare assessment, equine-assisted services evaluation, and safety monitoring in equestrian environments. Existing approaches to animal behavior recognition typically focus on single species in isolation, rely solely on facial expression analysis while ignoring full-body posture, or employ flat classification architectures that fail under the severe class imbalances characteristic of naturalistic behavioral datasets. Fu...
Buckley CMP, Hyde RM, Freeman SL.Artificial intelligence (AI) is becoming increasingly prevalent in the modern world, including in veterinary medicine. This cross-sectional study aimed to investigate horse carers' attitudes towards using AI use in equine care. Methods: An online survey was distributed to UK horse owners/carers in 2025, covering participants' demographics and use of AI and their opinions of AI for equine care. Statistical analysis included descriptive statistics, categorisation of free-text responses and logistic regression to determine factors associated with opinions. Results: Ninety-seven resp...
Kovács BA, Topál J, Gergely A.The relationship between horses and humans is often described as cooperative and affective, yet empirical studies on horse-rider bond remain scarce. Previous findings on horse-human relationships yielded conflicting results on whether and how horses show bonding like behaviour toward their owners. Objective: We tested whether horses show partner-specific approach and proximity toward their primary rider compared with an unfamiliar experimenter in an adapted Strange Situation Test, and whether the rider's presence was associated with behavioural patterns indicative of safe haven and secure base...
Jastrzębska E, Pawłowska A, Čoudková V, Baštýřová Brutovská A, Lansade L, Górecka-Bruzda A.The demand for horse housing that allows social contact, free movement, and continuous access to forage is increasing. Active stables, equipped with automatic feeders, aim to meet these needs by offering conditions closer to natural living. It is not known whether 'active stable' influences horse fear and human-oriented behaviour. This study compared the behaviour of horses housed in active stable (N = 24) and traditional stable (N = 22) to assess responses to novelty, sudden stimuli, and interactions with humans. We also examined the effects of breed type, age, and weekly riding workload....
Hiney K, Anderson K, Brady C.Accurate interpretation of affective state (AS) of animals is critical to assessment of their wellbeing. Although horse owners may appreciate the importance of this skill, many lack the ability to interpret AS accurately. Objective: To test if the online course Recognizing Affective States in Equine (RAiSE) improves participants' assessment of AS in horses and increases use of AS in management. Methods: Participants completed pre (PRE), post (POST), and 90 day post (90POST) course surveys to assess accuracy in identifying AS in 20 videos, as well as use of AS in their horse interactions. Pre/p...
Gulcelik GE, Sever E, Atalay B, Dursun E, Memisoglu I.PurposeThis study aimed to assess the acute effects of hippotherapy performed on different seating surfaces on sitting balance and walking speed in children with special needs.Materials and MethodsChildren aged 3-18 years with special needs were included. Participants were assigned to three groups: Group 1 (Saddle), Group 2 (No saddle, direct horse contact), and Group 3 (Saddle with additional texture material). Each group received a 30-min hippotherapy session in a riding arena. Sitting balance was measured with the BeCure balance system, and walking speed was assessed using the 10-meter walk...
Schmidt J, Wartenberg-Demand A, Forstmeier S.Preventive approaches for depression in adults aged 50 years and older have received little attention, despite increasing needs arising from demographic changes. In particular, subclinical depression is often underdiagnosed and associated with anxiety, a poorer quality of life, and greater need for assistance from the healthcare system. This multicentre, randomised, controlled phase III trial investigated if Equine-Assisted Biographical Work (EABW) is effective to improve subclinical depression. Qualified sites in Germany enrolled 52 participants ≥ 50 years (Full Analysis Set (FAS),...
Nyberg L, Blokhuis MZ, McLean A, Hartmann E.Previous research has highlighted a gap between scientific evidence and its application in equestrian practice, leading to concerns about horse welfare and human safety. Riding schools present an important platform for promoting science-based practices, as they bring together riders of all ages and levels and serve as sites for equestrian education and for shaping attitudes toward horse welfare. Yet, the teaching in riding schools is often rooted in traditional practices. Therefore, mapping current educational methods and exploring how teaching and learning are perceived by both riding school ...
Telhede EH, Bräutigam Ewe M, Jormfeldt H.Mental health, encompassing self-esteem, confidence, physical activity, and social interaction, is essential for the well-being of children and adolescents and supports executive functions crucial for school performance. Mental ill health among young people is increasing in Sweden, with rising rates of self-reported problems, psychiatric diagnoses, and prescriptions of psychotropic medication. The aim of this study was to explore the experiences of equine-assisted interventions (EAI) among children and adolescents with anxiety-related mental ill health in southern Sweden. A qualitative design ...
Hernández-Espeso N, Bronchud LD, Bernabé-Valero G.: Anxiety is highly prevalent among individuals living with disability, chronic illness, or hospitalisation, yet it often remains insufficiently addressed in healthcare settings. Animal-assisted therapy (AAT) has been proposed as a complementary intervention to reduce anxiety; however, existing evidence is fragmented across populations and methodologies. : A systematic review was conducted following PRISMA 2020 guidelines. The review protocol was registered in PROSPERO (CRD42024494109); no amendments were made to the protocol after registration. Four databases (Scopus, APA PsycInfo, Web of Sci...
Jardat P, Destrez A, Damon F, Tanguy-Guillo N, Lainé AL, Parias C, Reigner F, Ferreira VHB, Calandreau L, Lansade L.Olfaction is the most widespread sensory modality animals use to communicate, yet much remains to be discovered about its role. While most studies focused on intraspecific interactions and reproduction, new evidence suggests chemosignals may influence interspecific interactions and emotional communication. This study explores this possibility, investigating the potential role of olfactory signals in human-horse interactions. Cotton pads carrying human odours from fear and joy contexts, or unused pads (control odour) were applied to 43 horses' nostrils during fear tests (suddenness and novelty ...
Brumpton HL, Kargas N.Therapeutic horse riding (THR) is a non-traditional intervention that may support mental well-being in individuals with autism spectrum conditions. Despite growing interest, most research has focused on children and has tended to privilege practitioner or caregiver perspectives, leaving autistic adults underrepresented. This qualitative study explores the psychological benefits and systemic barriers associated with THR among Autistic adults, drawing on perspectives from both clients and practitioners. Semi-structured interviews were conducted with six Autistic clients and four practitioners, a...
Corrigan RH, Pierard M, Davies E, Marlin D, Evans S, Williams JM.Human-horse relationships encompass diverse roles, from companion to competition partner. The impact of such bonds informs owner decision-making regarding horse management and veterinary care, yet standardised instruments to measure these unique bonds are limited. Objective: To develop the Human-Equine Attachment Scale (HEAS), a novel instrument to measure the multi-faceted dimensions of human-horse attachment. Methods: Cross-sectional design using a self-administered psychometric instrument. Methods: Initial items were developed through a systematic review of human and animal attachment resea...
Rönnow E, Roth LSV.Compared to other companion animals, our understanding of the human-horse relationship is limited, particularly from the horse's perspective. This pilot study examined whether horses (N = 30) show a bias towards their owner in a reunion in the presence of both the owner and a stranger. Afterwards, the horses were also presented with the odor of the owner and a stranger. Both tests were video recorded for behavioral analyzation. No significant owner-directed bias was observed at the group level in either the reunion test or the odor test. Nonetheless, in the reunion test, owner bias in physical...
Tripon MA, Manolăchescu D, Papuc I, Daradics Z, Crecan CM.Emotional contagion between horses and humans is a key aspect of their interaction, influencing welfare, training, and therapy, yet current methods for measuring this phenomenon lack standardization and consistency. Objective: The aim of this study was to verify what methods are used to assess emotional contagion in horse-human interactions, and what outcomes have been reported. Methods: A systematic search of Google Scholar, Web of Science, Scopus, PubMed, and Science Direct was conducted up to March 2024. Peer-reviewed studies assessing emotional transfer through behavioral and/or physiologi...
Manolăchescu D, Tripon M, Crecan C, Tătaru M, Papuc I.Emotional contagion in human-horse interactions has been widely studied; however, the role of body language in stress transfer remains insufficiently explored. Unassigned: This study examines whether human emotional states, particularly stress and anxiety, influence horses and whether the transmission occurs primarily through body language. Unassigned: A repeated-measures within-subjects design was used. The order of interaction styles was randomized across subjects during 33 HCIs. Participants were categorized as high-anxiety (HA) or low-anxiety (LA) based on State Anxiety Scale scores and he...
Held A, Hubbard K, Nazarenko E, Marchand W.: Equine-assisted services are being increasingly utilized as complementary interventions for military veterans who have experienced trauma. However, rigorous research is lacking, and randomized controlled trials are needed. The H.O.O.V.E.S. Intensive intervention was developed for this population. This intensive program is an equine-assisted learning approach developed for veteran and active-duty military trauma survivors. The program integrates equine-assisted learning, peer mentorship and experiential learning in a residential retreat format. The primary aim of this pilot study was to deter...
Kogstad N, Christiansen SE, Ulberg R, Fiskum C.The integration of horses into psychotherapy has gained popularity over recent decades, offering unique therapeutic opportunities that may enhance emotional healing, empathy, and relational trust. This study investigates the perspectives of experienced psychotherapists on why they incorporate horses into their therapeutic practices. In-depth interviews were conducted with ten clinicians (eight female, two male) from diverse theoretical orientations. The data, which were analyzed using reflexive thematic analysis, revealed four key themes: "Supporting presence and getting to the heart of things...
Sivagurunathan R, Senathirajah ARBS, Sivagurunathan L, Arokiasamy L, Qazi S, Haque R, Su Y.This study explores how equine-assisted leadership development (EALD) interventions activate experiential processes that reshape leaders' self-concept, relational schemas, and behaviors. A conceptual model is proposed to explain how non-verbal interaction with horses catalyzes transformational learning. Unassigned: A qualitative exploratory design was employed to examine leaders' experiences over 12 months following reintegration into their workplaces. Eight leaders ( = 8) attended a 5-day EALD program, engaging in "join-up" exercises with horses. Data were analyzed through reflexive the...
Gabriels RL, Pan Z, Dechant B, Agnew JA, Brim N, Mesibov G.This study expands previous equine-assisted intervention research by evaluating the effectiveness of therapeutic horseback riding (THR) on self-regulation, socialization, communication, adaptive, and motor behaviors in children with autism spectrum disorder (ASD). Methods: Participants with ASD (aged 6-16 years; N = 127) were stratified by nonverbal IQ standard scores (≤85 or >85) and randomized to 1 of 2 groups for 10 weeks: THR intervention or a barn activity (BA) control group without horses that used similar methods. The fidelity of the THR intervention was monitored. Participants ...
Smith AV, Proops L, Grounds K, Wathan J, McComb K.Whether non-human animals can recognize human signals, including emotions, has both scientific and applied importance, and is particularly relevant for domesticated species. This study presents the first evidence of horses' abilities to spontaneously discriminate between positive (happy) and negative (angry) human facial expressions in photographs. Our results showed that the angry faces induced responses indicative of a functional understanding of the stimuli: horses displayed a left-gaze bias (a lateralization generally associated with stimuli perceived as negative) and a quicker increase in...
Borgi M, Loliva D, Cerino S, Chiarotti F, Venerosi A, Bramini M, Nonnis E, Marcelli M, Vinti C, De Santis C, Bisacco F, Fagerlie M, Frascarelli M....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. reduc...
Proops L, McComb K.Recent research has shown that domestic dogs are particularly good at determining the focus of human attention, often outperforming chimpanzees and hand-reared wolves. It has been suggested that the close evolutionary relationship between humans and dogs has led to the development of this ability; however, very few other domestic species have been studied. We tested the ability of 36 domestic horses to discriminate between an attentive and inattentive person in determining whom to approach for food. The cues provided were body orientation, head orientation or whether the experimenters' eyes we...
Proops L, McComb K.It has recently been shown that some non-human animals can cross-modally recognize members of their own taxon. What is unclear is just how plastic this recognition system can be. In this study, we investigate whether an animal, the domestic horse, is capable of spontaneous cross-modal recognition of individuals from a morphologically very different species. We also provide the first insights into how cross-modal identity information is processed by examining whether there are hemispheric biases in this important social skill. In our preferential looking paradigm, subjects were presented with t...
Seguin JC, Walker RD, Caron JP, Kloos WE, George CG, Hollis RJ, Jones RN, Pfaller MA.During a 13-month period, 11 equine patients visiting a veterinary teaching hospital for various diagnostic and surgical procedures developed postprocedural infections from which methicillin (oxacillin)-resistant Staphylococcus aureus (MRSA) strains were isolated. The S. aureus isolates were identified by conventional methods that included Gram staining, tests for colonial morphology, tests for clumping factor, and tests for coagulase and urease activities and were also tested with the API STAPH IDENT system. Antimicrobial susceptibility tests were performed by the disk diffusion method. The b...
Tarazona AM, Ceballos MC, Broom DM.Excessive human population growth, uncontrolled use of natural resources, including deforestation, mining, wasteful systems, biodiversity reduction by agriculture, and damaging climate change affect the existence of all animals, including humans. This discussion is now urgent and people are rethinking their links with the animals we use for clothing, food, work, companionship, entertainment, and research. The concepts of one health, one welfare, and one biology are discussed as a background to driving global change. Nothing should be exploited without considering the ethics of the action and t...
Nawroth C, Langbein J, Coulon M, Gabor V, Oesterwind S, Benz-Schwarzburg J, von Borell E.Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioral but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and interact with their environment is of major importance for a range of stakeholders, from citizens to politicians to cognitive ethologists to philosophers. This review aims to outline the current state of farm animal cognition research and focuses on u...
Fureix C, Menguy H, Hausberger M.Experiencing acute pain can affect the social behaviour of both humans and animals and can increase the risk that they exhibit aggressive or violent behaviour. However, studies have focused mainly on the impact of acute rather than chronic painful experiences. As recent results suggest that chronic pain or chronic discomfort could increase aggressiveness in humans and other mammals, we tested here the hypothesis that, in horses, aggression towards humans (a common source of accidents for professionals) could be linked to regularly reported vertebral problems of riding horses. Results: Vertebra...
Maros K, Gácsi M, Miklósi A.Twenty domestic horses (Equus caballus) were tested for their ability to rely on different human gesticular cues in a two-way object choice task. An experimenter hid food under one of two bowls and after baiting, indicated the location of the food to the subjects by using one of four different cues. Horses could locate the hidden reward on the basis of the distal dynamic-sustained, proximal momentary and proximal dynamic-sustained pointing gestures but failed to perform above chance level when the experimenter performed a distal momentary pointing gesture. The results revealed that horses coul...
Wilkin S, Ventresca Miller A, Taylor WTT, Miller BK, Hagan RW, Bleasdale M, Scott A, Gankhuyg S, Ramsøe A, Uliziibayar S, Trachsel C, Nanni P....Dairy pastoralism is integral to contemporary and past lifeways on the eastern Eurasian steppe, facilitating survival in agriculturally challenging environments. While previous research has indicated that ruminant dairy pastoralism was practiced in the region by circa 1300 BC, the origin, extent and diversity of this custom remain poorly understood. Here, we analyse ancient proteins from human dental calculus recovered from geographically diverse locations across Mongolia and spanning 5,000 years. We present the earliest evidence for dairy consumption on the eastern Eurasian steppe by circ...
Hoagwood KE, Acri M, Morrissey M, Peth-Pierce R.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 2...
Lampe JF, Andre J.This study has shown that domestic horses are capable of cross-modal recognition of familiar humans. It was demonstrated that horses are able to discriminate between the voices of a familiar and an unfamiliar human without seeing or smelling them at the same moment. Conversely, they were able to discriminate the same persons when only exposed to their visual and olfactory cues, without being stimulated by their voices. A cross-modal expectancy violation setup was employed; subjects were exposed both to trials with incongruent auditory and visual/olfactory identity cues and trials with congruen...
Sankey C, Richard-Yris MA, Henry S, Fureix C, Nassur F, Hausberger M.A central question in the interspecific human/animal relationship is how domestic animals perceive humans as a significant element of their environment. In this study, we tested the hypothesis that the use of positive or negative reinforcement in horse training may have consequences on the animals' perception of humans, as a positive, negative or neutral element. Two groups of ponies were trained to walk backwards in response to a vocal order using either positive or negative reinforcement. Heart rate monitors and behavioural observations were used to assess the animals' perception of humans o...
von Lewinski M, Biau S, Erber R, Ille N, Aurich J, Faure JM, Möstl E, Aurich C.Although some information exists on the stress response of horses in equestrian sports, the horse-rider team is much less well understood. In this study, salivary cortisol concentrations, heart rate (HR) and heart rate variability (HRV), SDRR (standard deviation of beat-to-beat interval) and RMSSD (root mean square of successive beat-to-beat intervals) were analysed in horses and their riders (n=6 each) at a public performance and an identical rehearsal that was not open to the public. Cortisol concentrations increased in both horses and riders (P<0.001) but did not differ between performan...
McDaniel Peters BC, Wood W.This systematic mapping review mapped current knowledge of equine-assisted interventions for people with autism to help guide future practice and research. Thirty-three studies including children and adolescents with autism, 3 of which confirmed diagnoses, were reviewed. Five types of equine-assisted activities were identified across 25 studies, with reported improvements in behavior, social interaction, and communication. Four types of equine-assisted therapies were identified across 8 studies, with reported improvements in motor control and self-care. Different approaches to therapeutic ridi...
Minetti AE.By refining a previously published model, a simple equation for the estimation of the mechanical internal work during locomotion is presented. The only input variables are the progression speed, the stride frequency and the duty factor, i.e. the fraction of the stride duration at which a foot is in contact with the ground. The inclusion of this last variable, easily measurable, allows to obtain a single equation for both walking and running. The model predictions have been compared with the mechanical internal work experimentally obtained on humans in several conditions: speeds (range 0.8-3.3 ...
Sankey C, Henry S, André N, Richard-Yris MA, Hausberger M.Animals' ability for cross-modal recognition has recently received much interest. Captive or domestic animals seem able to perceive cues of human attention and appear to have a multisensory perception of humans. Results: Here, we used a task where horses have to remain immobile under a vocal order to test whether they are sensitive to the attentional state of the experimenter, but also whether they behave and respond differently to the familiar order when tested by a familiar or an unknown person. Horses' response varied according to the person's attentional state when the order was given by a...
Kern JK, Fletcher CL, Garver CR, Mehta JA, Grannemann BD, Knox KR, Richardson TA, Trivedi MH.Anecdotal reports and some studies suggest that equine-assisted activities may be beneficial in autism spectrum disorders (ASD). Objective: To examine the effects ofequine-assisted activities on overall severity of autism symptoms using the Childhood Autism Rating Scale (CARS) and the quality ofparent-child interactions using the Timberlawn Parent-Child Interaction Scale. In addition, this study examined changes in sensory processing, quality of life, and parental treatment satisfaction. Methods: Children with ASD were evaluated at four time points: (1) before beginning a 3-to-6 month waiting ...
Fureix C, Jego P, Sankey C, Hausberger M.This study aimed to determine whether horses have a kind of memory of humans (based on previous interactions), leading to a general significance of humans revealed by their reactions to humans in subsequent interactions. Subjects were 59 adult horses used to interact daily with humans. Three types of behavioural tests involving an unknown experimenter evaluated three possibly different memorized types of human-animal interactions (not work-related, using work-related objects, unfamiliar working task). We also performed standardized observations of routine interactions between each horse and it...
Keeling LJ, Jonare L, Lanneborn L.The heart rates (HR) of horses and the people leading them (10 horses, 20 people), and riding them (17 horses, 17 people), were recorded in an indoor arena. The horses were Swedish leisure horses of mixed ages, sex and breed. All except two of the people were female and all were of mixed age and riding experience. Each horse-human pair walked or rode between points A and B (30m) four times on each test occasion. However, just before the fourth pass, participants were told that an umbrella would be opened as they rode, or led, the horse past the assistant. The umbrella was not opened, so this p...
Friedman E, Krause-Parello CA.There is ample evidence that human-animal interaction (HAI) is associated with health. Studies encompass three general categories: those that compare companion animal owners with individuals who do not own companion animals, those examining brief, 'one-off' contacts with animals, and those that review animal-assisted interventions. The health benefits demonstrated typically include reductions in depression and loneliness, while enhancing social interaction or social skills, and decreasing anxiety and arousal. Other health benefits associated with companion animals include the promotion of exer...
Lönker NS, Fechner K, Wahed AAE.One Health (OH) is a crucial concept, where the interference between humans, animals and the environment matters. This review article focusses on the role of horses in maintaining the health of humans and the environment. Horses' impact on environmental health includes their influence on soil and the biodiversity of animal and plant species. Nevertheless, the effect of horses is not usually linear and several factors like plant-animal coevolutionary history, climate and animal density play significant roles. The long history of the relationship between horses and humans is shaped by the servic...
Farmer K, Krueger K, Byrne RW.Most horses have a side on which they are easier to handle and a direction they favour when working on a circle, and recent studies have suggested a correlation between emotion and visual laterality when horses observe inanimate objects. As such lateralisation could provide important clues regarding the horse's cognitive processes, we investigated whether horses also show laterality in association with people. We gave horses the choice of entering a chute to left or right, with and without the passive, non-interactive presence of a person unknown to them. The left eye was preferred for scannin...

Lagarde J, Kelso JA, Peham C, Licka T.The authors studied the interaction between rider and horse by measuring their ensemble motions in a trot sequence, comparing 1 expert and 1 novice rider. Whereas the novice's movements displayed transient departures from phase synchrony, the expert's motions were continuously phase-matched with those of the horse. The tight ensemble synchrony between the expert and the horse was accompanied by an increase in the temporal regularity of the oscillations of the trunk of the horse. Observed differences between expert and novice riders indicated that phase synchronization is by no means perfect bu...
Smith AV, Proops L, Grounds K, Wathan J, Scott SK, McComb K.The ability to discriminate between emotion in vocal signals is highly adaptive in social species. It may also be adaptive for domestic species to distinguish such signals in humans. Here we present a playback study investigating whether horses spontaneously respond in a functionally relevant way towards positive and negative emotion in human nonverbal vocalisations. We presented horses with positively- and negatively-valenced human vocalisations (laughter and growling, respectively) in the absence of all other emotional cues. Horses were found to adopt a freeze posture for significantly longe...

Methods: Pre-postoperative follow-up with a 12-week intervention and 12-week washout period after intervention. Methods: A human performance laboratory with 6 camera video motion capture systems for testing. Methods: Eleven children (age 5-13y, average 8y) with SDCP, 8 children (age 5-13y, average 8y) without disabilities. Methods: Hippotherapy intervention performed at 3 therapeutic horseback riding centers. Met...
Bachi K, Terkel J, Teichman M.This article describes the theoretical-conceptual frame of equine-facilitated psychotherapy (EFP) for adolescents at-risk, the unique components of this intervention, and its implementation in an evaluation study. The study was conducted at a residential treatment facility for adolescents at-risk. We examined the outcomes of EFP on self-image, self-control, trust and general life satisfaction. Fourteen resident adolescents comprised the treatment group, and were compared with a matched group of 15 residents who did not receive EFP (control).
