Abstract
PURPOSE:
Hippotherapy is used by rehabilitation professionals to assist children with various diagnoses. Despite parents’ pivotal decision-making role regarding their children’s life and treatment, little is known about their perceptions of hippotherapy’s utility. This pilot study explored parents’ opinions regarding hippotherapy’s impact on their child’s life habits, as guided by the Disability Creation Process model.
METHODS:
A survey was conducted in September/October 2017 with the parents of children with varied diagnoses receiving hippotherapy in Quebec. The survey asked parents to priority rank life habit categories and then grade hippotherapy’s service characteristics and impact on children’s life habits. Descriptive analysis and proportion tests were used to analyze the data.
RESULTS:
The parents of 26 children completed the survey. These children were on average seven years old with multiple diagnoses (e.g., autism spectra, developmental delay). A positive impact was perceived for 10 of 12 life habit categories, with a statistically significant association found with Mobility and Interpersonal relationships. It was not possible to calculate the association between the profession involved and hippotherapy effects due to the small sample size.
CONCLUSION:
This investigation provides some promising results regarding the benefits of hippotherapy for children’s life habits.
Introduction
Hippotherapy, the use of equine movement to reach functional goals, is an intervention strategy used by occupational therapists (OT), physiotherapists (PT) and speech-language pathologists (SLP) in various countries and with children with various diagnoses [1]. The horse’s movement is transmitted to the rider, providing sensory, neuromotor and cognitive stimulations as well as providing a walking simulation, as the three-dimensional movement of the horse’s walk is similar to that of humans [1]. These stimulations, which are transmitted by the use of a dynamic seat, may be more readily provided compared to other approaches used in rehabilitation [1]. The use of hippotherapy must be supported by an evaluation that reveals the child’s level of function and challenges performing some movements or tasks that can be addressed by the use of the horse. The professional then chooses a horse whose characteristics must be consistent with the profile of the child and the therapeutic objectives. Intervention often consists of mounting, activities on horse (variation of movement, position of the child on horse, etc.) and dismounting. Hippotherapy requires the involvement of a trained therapist, a handler following the therapist’s instructions to guide the horse, and a side walker who assists the therapist during activities.
Most of the available studies concerning the effects of hippotherapy address motor function, including variables such as balance or spasticity [2, 3, 4, 5, 6]. These investigations have mostly been conducted with individuals with cerebral palsy and autism spectrum disorder [7, 8]. In contrast, limited investigation has been conducted regarding the effects of hippotherapy on the realization of life habits [9], as described in Fougeyrollas et al.’s [10] Disability Creation Process (DCP) model. According to this model, individuals can experience social participation in the 12 categories of life habits when the interaction of personal and environmental factors permit the full realization of these life habits. Social participation is defined as the successful accomplishment of life habits resulting from the interaction between the personal and environmental factors. Life habit categories include the following: Communication, Community and spiritual life, Education, Employment, Housing, Interpersonal relationships, Mobility, Nutrition, Personal care and Health, Physical fitness and psychological well-being, Recreation and Responsibility. As noted by Levasseur et al. [11], the clarity of the elements of the DCP model provide support for its use. The DCP model is also relevant to hippotherapy in that this model can fully describe this modality. In summary, the global understanding provided by the DCP model of the interactions affecting participation and life habits supports its utility for research regarding hippotherapy.
Positive effects of hippotherapy have been demonstrated for certain life habit categories: Communication [12, 13, 14, 15, 16, 17], Interpersonal relationships [12, 13, 15, 17, 18, 19] and Mobility [12, 13, 14, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29]. However, several life habit categories have not been considered, for example, Community and spiritual life, and Responsibility. In addition, there has been limited investigation of parents’ perceptions [30, 31], which is surprising given their expertise about their children’s daily functioning and their pivotal role in making decisions about their treatment.
The overall objective of our pilot study is to explore the association between hippotherapy and the life habit categories of children with a motor deficit or neurodevelopmental impairment, from the point of view of their parents. Our hypothesis was that parents would perceive a positive impact of hippotherapy on life habits. Specifically, three questions were posed: (1) Which life habits are positively associated with hippotherapy from the parents’ perspectives? (2) Which of these life habits are considered the most important for the parents? (3) Is there an association between types of hippotherapy (OT, PT, SLP) and the impact perceived by the parents? Consistent with the DCP model, in addressing these questions, a description was obtained of the personal factors of children who receive hippotherapy, the reasons invoked by parents for trying this therapy, and the facilitators and obstacles invoked by parents for recommending it.
Methods
Design
A descriptive survey design [32] was used, which was appropriate for capturing parents’ perceptions regarding hippotherapy and their children’s life habits. This research was conducted in collaboration with two organizations offering hippotherapy services to children in the province of Quebec (Canada). Currently in this province, hippotherapy is provided in privately-funded settings. Research ethics approval for this study was obtained (#2017-559) from the Scientific Evaluation Committee and Research Ethics Committee of the Centre intégré universitaire de santé et de services sociaux de la Capitale-Nationale. The completion and submission of online and paper questionnaires, which included no personally identifying information, by parents was considered to be informed consent; this point was clearly stated in the questionnaire information.
Participants
The parents of children with a motor impairment or a neurodevelopmental disorder from the two hippotherapy centers were recruited, respecting the following inclusion criteria: the child had received at least 10 hippotherapy sessions between May 2015 and August 2017; s/he was between 2 and 18 years old at the time of hippotherapy; the other parent had not already completed the questionnaire; and the parent was able to read, understand and respond to written French.
A sample size calculation was conducted based on a proportion test and our hypothesis. The software G*power was used with the following parameters: power of 0.8;
Measures
In the absence of an existing questionnaire based on hippotherapy and social participation in the 12 life habit categories, a self-administered questionnaire was developed. This questionnaire was based on available theory about hippotherapy, life habits, the LIFE-H 4.0 (33) and the clinical experience of the first author. The questionnaire included four sections; the first of these addressed parents’ identification of the most important life habits from a list of choices to improve with their child, by selecting up to three life habit categories. Specific examples for each category, which consisted of related activities, were included to support the parents in making their choices. The second section dealt with interventions received with the hippotherapy modality. Parents were asked why they wanted to use hippotherapy, the number of sessions their child received, the start and end (if applicable) dates of the interventions, and the types of health professionals who provided the services. The number and nature of incidents (e.g., fall, bite, emergency transfer) or other events (e.g., medical condition, family event, accident) that occurred during hippotherapy sessions were also requested. Next, parents were asked to indicate the perceived impacts of hippotherapy on their child’s realization of the 12 life habit categories. To achieve this objective, each category was linked to a six-level non-neutral scale with three negative levels (
The questionnaire was pre-tested regarding its clarity, feasibility, duration and relevance with two parents of children with disabilities, a resource person with expertise regarding the DCP, a PT, and an SLP using hippotherapy in their practice. These individuals’ feedback was used to revise the questionnaire.
Procedure
The parents were invited to undertake the questionnaire by using either an online or paper version, according to their preference. The online survey was conducted using LimeSurvey. The partner organizations sent an offer of participation via email to parents who had agreed, at the time when their child started to receive hippotherapy services, to be contacted for research purposes. The organizations also published the same offer of participation on their respective Facebook pages. Paper versions were made available at the three practice sites (one organization had two practice sites) with an explanatory leaflet about the research project and a deposit box for completed anonymized questionnaires. Two reminders of the offer of participation were sent by email and social network by the partner organizations during the two months during which the questionnaire was available.
Data analysis
The data analysis was performed using the Statistical Package for Social Sciences 24 (34) software. The sociodemographic data and the general characteristics of the hippotherapy services were analyzed with descriptive analyses (total, frequency, mean). The responses to the open-ended questions were categorized by the first author. The selections of up to three important life habit categories and the perceived impact levels were summarized using frequencies. It was then possible to determine the proportion of positive impacts (
Results
Personal factors of children who received hippotherapy
Twenty-six questionnaires were completed, with three of these being partially completed. Information about the personal factors of the children who received hippotherapy can be found in Table 1. Twenty-three children were receiving other services such as psychology, chiropractic, music therapy and zootherapy.

In this survey, hippotherapy was delivered most frequently by OTs (see Table 2). As a result of the limited involvement of the other professions (PTs and SLPs), it was impossible to meaningfully analyze the relationship between the type of professional implementing hippotherapy and the impact perceived by the parents in the 12 life habit categories.
Discussion
This research survey revealed that children receiving hippotherapy services have various diagnoses that are not limited to the most studied diagnoses regarding hippotherapy (e.g., cerebral palsy). As well, the investigation documented all life habits relative to the DCP model in association with hippotherapy (e.g., Personal care and Nutrition) compared to the existing literature in which the focus was more typically upon individuals’ motor functions.
The identification of the reasons that led parents to take an interest in and support hippotherapy adds new knowledge. Among other aspects, this finding demonstrates the range of elements that support the use of this relatively new modality in Quebec, versus the few inconveniences identified. Parents reported more potential benefits than risks, despite these risks being greater with hippotherapy compared to traditional approaches. In turn, as also previously noted (35), this finding reinforces the importance both of informed consent and the involvement of qualified therapists in the use of this modality. Parents must develop a realistic idea of the modality, and the implication of a trained therapist helps decrease the risks and supports informed consent.
This investigation has furthered understanding regarding the facilitators and obstacles to hippotherapy from the parents’ point of view. The main facilitator identified in this study justifying the recommendation of hippotherapy is its global benefits, considered to encompass both physical and psychosocial benefits. This finding is consistent with the results of Léveillé et al.’s [31] study in which parents reported physical, emotional and cognitive benefits as well as a positive impact on the social environment and occupations. This finding is also supported by Debuse et al.’s [30] investigation that reported the presence of both physiological and psychological benefits from parents’ perspectives. The child-horse relationship has previously been identified as beneficial or potentially beneficial for the child by parents of children receiving or waiting for hippotherapy services [31], a finding that is consistent with the current study results. Some other facilitators, which have not previously been reported in the literature, are reported by this survey (Table 4): a reduction of the child’s inadequate behaviors; contact with nature; responsibility taken by the child; sensory stimulation; and the fact that hippotherapy resembles a leisure pursuit from the parents’ perspective.
Regarding the barriers to the use of hippotherapy, a predominant reason that emerged from the current study was the cost associated with this modality. In contrast, the risk of injury or fall was not identified by the parents. This latter result is consistent with the findings of Léveillé et al.’s [31] study, in which parents reported little risk to the use of hippotherapy compared to its benefits, mentioning, among other elements, the presence of qualified therapists. These authors also pointed out that the associated risks did not seem to be a major concern and that there seemed to be minimization of risks by parents. Some other obstacles that were reported by parents in the current survey, which have not previously been identified in the literature, included the child’s social skills deficits and difficulties managing emotions. This finding regarding social skills is interesting given that it is also one of the reasons mentioned by parents for trying hippotherapy. The fact that this area is also considered an obstacle reinforces the importance of the relationship established between the humans and horses.
While recognizing the prudence required given the limited sample size, the current study revealed that, according to their parents, children’s life habits are most often positively influenced by hippotherapy. Mobility and Interpersonal relationships are the life habits for which a statistically significant association with hippotherapy was revealed when the potentially neutral responses regarding impact were removed. These findings are consistent with the results of Potvin-Bélanger et al.’s [1] systematic review. It is worthy of note that the life habits considered more important by parents were among those for which a perceived positive association with hippotherapy was reported. Although some prudence is required in the interpretation of this finding insofar as the parents may be more inclined to see a positive influence in these areas, it is also logical that parents might be more inclined to continue their children’s involvement in hippotherapy if they believe that this modality has a positive influence on areas they believe to be important.
It was not possible to measure a significant statistical relationship between the perceived benefits of hippotherapy and the type of therapist involved due to an insufficient sample size. However, the current research revealed that more OTs appear to be involved in the use of hippotherapy in Quebec compared to PTs and SLPs. This finding may not be surprising given occupational therapy’s focus upon a wide variety of daily living activities, for example, feeding (Nutrition), dressing (Personal care), writing (Education, Communication), playing (Recreation), attending school (Education), using assistive devices (Mobility), and taking part in significant social activities (Interpersonal relationship) (36). In comparison, the interventions of PTs and SLPs tend to be associated with a narrower range of life habit categories (respectively Mobility and Recreation, and Communication and Interpersonal relationship).
Strengths and limitations
The survey questionnaire was guided by the rigorous and well-recognized DCP model. This model permitted the documentation of a large array of relevant variables for establishing a portrait of the intervention in hippotherapy in two dedicated clinics in Quebec. The survey was pre-tested by individuals possessing relevant expertise. In addition, the questionnaire was entirely anonymous, which made it possible to reduce the potential of social desirability among participants influencing their responses in favor of hippotherapy. Another strength of the study concerns the statistical analyses used. The proportion test permitted a measurement of the extent to which the responses of the subjects’ sample was representative of those of the actual parent population (37).
The main limitation of this study concerns the size of the sample obtained. The participation rate was lower than anticipated, despite the considerable efforts made to stimulate dissemination by the hippotherapy organizations. Several reasons may explain the obtained rate, including: the reduced time available for parents at the beginning of the school year; the impossibility of validating the number of emails sent by the organization due to confidentiality issues; and changes in parents’ email addresses. Given the large proportion of respondents whose children had hippotherapy interventions performed by OTs, it would have been necessary to obtain more responses in which the interventions were provided by other disciplines in order to answer our third research question. Regarding the positive results found for the first research question, some caution is required given the small number of subjects with which this proportion was revealed; that is, there may have been participant bias as the parents who decided to participate may have been more inclined to respond favorably. Due to the confidentiality concerns, little information was obtained regarding parents’ characteristics that may have influenced their perceptions. Given the lapse of time between the beginning and end of the hippotherapy interventions and the completion of the questionnaire, it is not possible to rule out the potential influence of a memory bias nor confusion between the effects of hippotherapy and other services received simultaneously by the majority of the children. Finally, it is possible that the perceived positive changes in life habits are related not only to the children’s participation in hippotherapy but also to its combination with the use of assistive devices and home adaptations.
Implications for future research
The use of standardized assessments and measures within experimental design studies would allow a more precise identification and comprehension of the effect of hippotherapy on life habit categories, as some life habits seem more important and positively influenced from the parents’ perspective. Further research should document the perception of therapists and their use of hippotherapy, as it would be beneficial to the understanding of hippotherapy in different settings and ensure a safe and relevant use regarding potential benefits and risks. Finally, other surveys, interviews and assessments using, for example, the Paediatric Activity Card Sort (38) could be conducted with the children to understand their experience and perceptions of the effect of hippotherapy on their life habits.
Conclusions
This survey conducted with parents of children receiving hippotherapy services from two organizations in Quebec revealed various facilitators and obstacles for recommending hippotherapy as well as parents’ prioritization of life habits for their children. The results also suggest a perceived global positive association between hippotherapy and 10 out of 12 life habit categories. Further research is needed to document the experience of professionals and children with hippotherapy and its benefits on life habits and social participation using experimental design studies and relevant tools.
