An exploration of German and British physiotherapists' views on the effects of hippotherapy and their measurement

Parasport: Effects on Musculoskeletal Function and Injury Patterns

➤

Sports participation can improve gait, muscle strength, and functional abilities in patients with a wide variety of disabilities. Para athletes are also at substantial risk for injury during sports participation.

➤

Ambulant athletes with cerebral palsy are at risk for soft-tissue injuries about the knee as well as foot and ankle injuries. Wheelchair athletes are at risk for osteoporotic fractures and shoulder girdle injuries. Limb-deficient athletes are prone to low back pain and overuse injuries of the contralateral extremity.

➤

Para athletes are vulnerable to abuse during sports participation, and physicians should promptly report any possible abuse or mistreatment.

➤

Orthopaedic surgeons should understand disability and sport-specific risk factors for injury in para athletes in order to initiate early management and injury prevention protocols.

The Short-term Effects of Hippotherapy and Therapeutic Horseback Riding on Spasticity in Children With Cerebral Palsy: A Meta-analysis

PURPOSE

We systematically reviewed the short-term effects of hippotherapy and therapeutic horseback riding (THR) on lower-limb muscle spasticity in children with cerebral palsy (CP).

METHODS

PubMed, EMBASE, Cochrane Library, and Google Scholar databases were searched for relevant quantitative studies. Treatment effects were coded using the Ashworth scale (AS) or modified Ashworth scale (MAS) in pre- and posttreatment evaluations. Of the 73 studies identified initially, 7 met the inclusion criteria.

RESULTS

Treatment was associated with positive effects on lower-limb muscle spasticity, as supported by the AS or MAS scores. However, repeated trials did not show a statistically significant difference from a single trial (Q = 2.95, P = .086).

CONCLUSION

Hippotherapy and THR can be used to treat lower-limb muscle spasticity in children with CP. However, repeated sessions did not show a better effect in reducing spasticity.

WHAT THIS ADDS TO THE EVIDENCE

This is the first meta-analysis to confirm that hippotherapy or THR can reduce lower-limb muscle spasticity in children with CP in the short term, but long-term effects on function still require further studies.

Physical therapy with hippotherapy compared to physical therapy alone in children with cerebral palsy: systematic review and meta-analysis

AIM

To compare the effects of physical therapy with hippotherapy versus physical therapy alone on the gross motor function of children and adolescents with cerebral palsy (CP).

METHOD

Electronic searches were conducted in January 2021. We included controlled trials of the gross motor function of children and adolescents with CP, aged 2 to 18 years. We extracted means, standard deviations, and changes from the baseline to the end of the intervention. We used the Cochrane Collaboration's tool modified by Effective Practice and Organization of Care (EPOC) to assess the methodological quality and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to verify evidence synthesis. We conducted the meta-analysis using Revman 5.3.

RESULTS

A total of 315 individuals from six studies were included. Both groups received physical therapy including strength, aerobic, stretch, and mobility exercises, and neurodevelopmental treatment. Studies presented high risk of bias. Both therapies presented similar effects for Gross Motor Function Measure scores, cadence, stride length, and speed during gait. The level of evidence was very low. The change was greater for the physical therapy with hippotherapy group, but inferior to the smallest real difference or the minimal detectable change.

INTERPRETATION

Physical therapy with hippotherapy presented similar effects to physical therapy alone on the gross motor function of children and adolescents with CP. Future studies should include larger sample sizes and studies with low risk of bias.

Effects of equine riding on static and dynamic mechanical contraction of the thighs and trunk muscles in inactive women

BACKGROUND AND OBJECTIVE

This study investigated whether equine riding affects static or dynamic mechanical contractions on the thighs and trunk muscles in inactive women.

METHODS

Participants consisted of 30 women with a mean (SD) age of 21.06 (0.44) years. They were randomly allotted as follows: equine group (EQG, n= 15) and control group (CON, n= 15). Two types of muscle contraction properties in their thighs and trunk were measured through a tensiomyography (static muscle tester) and an isokinetic device (dynamic muscle tester), respectively. Using the body weights of EQG and CON as covariates, a 2-way between-groups multivariate analysis of covariance was used to investigate group differences in the mechanical quantification of the thighs and trunk.

RESULTS

The effectiveness of 8 weeks of equine riding was hardly observed in a static muscle test, whereas in the dynamic muscle test, the dominant and non-dominant hip extensor/flexor, the dominant hip abductor/adductor, and trunk extensor in the EQG showed a significant increase, compared to no changes in the CON.

CONCLUSIONS

This study did not find any particular differences in a static muscle test in inactive women, but showed improvements in the dynamic mechanical properties of the thighs and trunk, which are major muscle groups related to spinal alignment.

Hippotherapy: a systematic mapping review of peer-reviewed research, 1980 to 2018

PURPOSE

Comprehensively and systematically map peer-reviewed studies of hippotherapy published over 30 years, from 1980 through 2018, from the perspective of a phased scientific approach to developing complex interventions as a guide to future research and practice.

METHODS

A systematic mapping review of research of hippotherapy was conducted. Searches of nine databases produced 3,528 unique records; 78 full-text, English-written studies were reviewed, the earliest of which was published in 1998. Data relevant to study aims were extracted electronically from these studies and analyzed using queries and pivot tables.

RESULTS

Children with cerebral palsy and physical therapists were most prevalent as participants and providers. Equine movement was hippotherapy's core component and mechanism. Early-phase outcomes-oriented research predominated. "Hippotherapy" was ambiguously defined as treatment strategies and comprehensive professional services, even as interventions grew more distinctive and complex. A treatment theory and proof of concept related to motor outcomes were established, and efficacy research with comparison conditions emerged.

CONCLUSIONS

Continuing research of complex interventions that integrate hippotherapy, equine movement as a therapy tool, is warranted. Attention to gaps in foundational scientific work concurrent with continued piloting and efficacy work will help to identify the most promising interventions worthy of replication, evaluation and widespread adoption.IMPLICATIONS FOR REHABILITATIONTo advance the evidence base of complex interventions that incorporate hippotherapy:•Proponents of hippotherapy need to define and represent hippotherapy to the public and in practice and research contexts as a therapy tool involving the use of the movement of horses by qualified professionals, rather than simply as a generic therapy with the help of a horse or simulated horse;•Providers of hippotherapy need to identify their professional degrees and certifications, and explicate their disciplinary perspectives that influence their selected components of intervention, related methods, and outcomes; and•Providers and researchers need to partner to develop an enablement theory of hippotherapy that links improved body functions with improved participation in everyday life and quality of life.

Use of outcome measures in children with severe cerebral palsy: A survey of U.K. physiotherapists

OBJECTIVES

To investigate the use of outcome measures for children with cerebral palsy (CP) by paediatric physiotherapists (PTs) who are based in the United Kingdom, as limited research exists regarding their use in this population, and to explore therapists' use of measures within different Gross Motor Function Classification System (GMFCS) levels and for different types of CP.

METHODS

A six-item online survey was advertised through two paediatric therapy special interest groups inviting physiotherapists to participate. Descriptive statistics (range, frequencies, and percentages) were used to analyse survey data.

RESULTS

Two hundred and seven physiotherapists returned completed survey questionnaires. One hundred and seventy-six (85%) therapists reported using a wide variety of outcome measures (57). Eighty-one per cent of therapists' responses for having "most difficulty" in identifying responsive outcome measures were for children with impaired mobility at GMFCS Levels IV-V and children with more significant body involvement (76%), for example, spastic quadriplegia or dyskinesia. Eighty-six per cent of therapists' responses for having "greatest ease" of identifying responsive outcome measures were for children within GMFCS Levels I-III and for children with less significant body involvement (72%), for example, hemiplegia. The variety of outcome measures used by therapists with children within GMFCS IV-V was less (16).

CONCLUSIONS

The majority (85%) of the PTs surveyed used outcome measures with children with CP, but 81% perceived a difficulty in identifying responsive measures for children with more severe impairments who are classified as GMFCS IV-V. The reasons for this perceived difficulty warrant investigation and may suggest a need for training regarding relevant measures and/or a need to develop new measures for this group of children.

Effect of Mechanical Horse Practice as New Postural Training in Patients With Neurological Disorders: A Pilot Study

Objective: From a dynamic system approach, this study evaluated the impact of a new training protocol using a mechanical horse on the postural coordination of brain-damaged patients.

Methods: Eighteen volunteer brain-damaged patients (i.e., post-stroke or traumatic brain injury) were recruited and randomly divided into an experimental group (horse group; n = 10, conventional therapy associated with horse-riding exercise on the mechanical horse for 30 min, twice a week, for 12 weeks) and a control group (n = 8; conventional therapy without intervention on the mechanical horse). Postural coordination was evaluated during pre- and post-tests through discrete relative phase (DRP) computation: ϕ_Head−Horse, ϕ_{Trunk−Horse.}

Results: A significant effect of used training has been showed, F_{(1, 15)} = 16.6 (p < 0.05) for all patients, concerning the trunk/horse coordination.

Conclusion: This pilot study results showed the impact of this new training method on the postural coordination of these patients. After 24 sessions, the coordination of the horse group patients differed from that of the control group, showing their ability to adapt to constraints and develop specific modes of postural coordination (trunk/horse antiphase) to optimize their posture.

Effect of hippotherapy simulator on pain, disability and range of motion of the spinal column in subjects with mechanical low back pain: A randomized single-blind clinical trial

BACKGROUND

Hippotherapy is a form of therapeutic exercise for conservative treatment of lumbar spine segmental instability and/or hypomobility in subjects with low back pain (LBP).

OBJECTIVE

The current study evaluates the effects of a hippotherapy simulator on pain, disability, and range of motion (ROM) of the spinal column in subjects with mechanical LBP.

METHODS

In a randomized clinical trial, 80 subjects were randomly assigned to either the control or intervention groups. All subjects underwent routine physiotherapy. In addition, the intervention group underwent hippotherapy with a hippotherapy simulator for 15 sessions, each lasting 15 minutes. Pain, disability, and ROM of the lumbar spinal column of the subjects were measured in the first and last physiotherapy sessions respectively.

RESULTS

Improvement in pain intensity was higher in the hippotherapy simulator group over the first eight days of treatment (Hippotherapy vs. Control Point changes: Day 12: p= 0.010; after treatment: p= 0.005). The hippotherapy simulator group had significantly higher improvement in disability score in comparison to the control group (p< 0.001); mean changes in the modified Schober test were not significant (p= 0.423).

CONCLUSION

The hippotherapy simulator decreased pain and disability in subjects with LBP; however, no additional improvement in lumbar spine ROM was observed.

Benefits of Hippotherapy and Horse Riding Simulation Exercise on Healthy Older Adults: A Systematic Review

OBJECTIVE

To provide an up-to-date research analysis on equine-assisted therapies and horse riding simulation exercise in older adults, and to suggest future directions in clinical practice and research. TYPE: Systematic review.

LITERATURE SURVEY

A comprehensive search of studies was performed in 4 electronic databases (Cochrane, PubMed, PEDro, and Web of Science) regarding the effects of equine-assisted therapies and horse riding simulation exercise in older adults. Eight articles were selected, 5 of them focused on hippotherapy, 2 on horse riding simulation, and a single article that used the 2 types of therapy.

METHODOLOGY

PRISMA guidelines were followed for the data extraction process.

SYNTHESIS

The studies were all randomized controlled trials, but not double-blind, so they were classified as level of evidence B. Duration of hippotherapy programs ranged from 8-12 weeks. Sessions lasted between 15 and 60 minutes and were performed 2-5 times per week. Interventions using a horse simulator spanned 8 weeks and were conducted for 20 minutes 5 times per week.

CONCLUSIONS

Results indicate that hippotherapy might improve balance, mobility, gait ability, and muscle strength, as well as could induce hormonal and cerebral activity changes in healthy older adults. Benefits of horse riding simulation could be limited to physical fitness and muscular activity.

Mechanisms of Change for Children Participating in Therapeutic Horse Riding: A Grounded Theory

AIM

To develop a model for understanding mechanisms of change in health outcomes for riders with disabilities participating in therapeutic horse riding (THR).

METHODS

Using grounded theory methods we collected and analyzed data from interviews with 16 child riders and 18 caregivers, teachers and primary therapists, and from participant-observation during THR sessions.

RESULTS

The central concept underpinning the model illustrating mechanisms of change was "gaining the tools to go on." Riders' experiences suggested the THR landscape (i.e., "where the tools are gathered") allowed for an expanded range of experiences in which riders could participate. Riders experienced an expansion of self-concept by learning to move, succeed, connect, and adapt (i.e., "the tools gathered") within the THR landscape. Riders then iteratively translated an expanded view of self into other environments, reflecting "how and where the tools are used."

CONCLUSION

Findings suggest that positive changes in health arise from riders' experiences of learning and agency within the THR therapeutic landscape, and from the influence of these experiences on a child's developing self-concept. This article considers the wider impact of THR on children's health, beyond a focus on changes in physical outcomes.

Translational Research for Occupational Therapy: Using SPRE in Hippotherapy for Children with Developmental Disabilities

Translational research is redefined in this paper using a combination of methods in statistics and data science to enhance the understanding of outcomes and practice in occupational therapy. These new methods are applied, using larger data and smaller single-subject data, to a study in hippotherapy for children with developmental disabilities (DD). The Centers for Disease Control and Prevention estimates DD affects nearly 10 million children, aged 2-19, where diagnoses may be comorbid. Hippotherapy is defined here as a treatment strategy in occupational therapy using equine movement to achieve functional outcomes. Semiparametric ratio estimator (SPRE), a single-subject statistical and small data science model, is used to derive a "change point" indicating where the participant adapts to treatment, from which predictions are made. Data analyzed here is from an institutional review board approved pilot study using the Hippotherapy Evaluation and Assessment Tool measure, where outcomes are given separately for each of four measured domains and the total scores of each participant. Analysis with SPRE, using statistical methods to predict a "change point" and data science graphical interpretations of data, shows the translational comparisons between results from larger mean values and the very different results from smaller values for each HEAT domain in terms of relationships and statistical probabilities.

Application of a tri-axial accelerometry-based portable motion recorder for the quantitative assessment of hippotherapy in children and adolescents with cerebral palsy

[Purpose] This case series aims to evaluate the effects of hippotherapy on gait and balance ability of children and adolescents with cerebral palsy using quantitative parameters for physical activity. [Subjects and Methods] Three patients with gait disability as a sequela of cerebral palsy (one female and two males; age 5, 12, and 25 years old) were recruited. Participants received hippotherapy for 30 min once a week for 2 years. Gait parameters (step rate, step length, gait speed, mean acceleration, and horizontal/vertical displacement ratio) were measured using a portable motion recorder equipped with a tri-axial accelerometer attached to the waist before and after a 10-m walking test. [Results] There was a significant increase in step length between before and after a single hippotherapy session. Over the course of 2 year intervention, there was a significant increase in step rate, gait speed, step length, and mean acceleration and a significant improvement in horizontal/vertical displacement ratio. [Conclusion] The data suggest that quantitative parameters derived from a portable motion recorder can track both immediate and long-term changes in the walking ability of children and adolescents with cerebral palsy undergoing hippotherapy.

Effects of hippotherapy on posture in individuals with Down Syndrome

Abstract Introduction: Individuals with Down syndrome (DS) have alterations that affect the musculoskeletal system, causing abnormal patterns, and alter the morphological anatomical and mechanical axes that provide intrinsic stability to the skeleton, and can trigger misalignments and orthopedic disorders in adulthood. Objective: The objective of student to evaluate posture and postural alignment before and after the hippotherapyin individuals with DS. Methods: Posture of five individuals with DS was evaluated by the software SAPO before and after 27 sessions the hippotherapy. Data were subjected to qualitative descriptive analysis using cluster and statistical analysis with the aid of the software Sigma Stat 2.0, considering differences as statistically significant at p-value < 5%. Results: Improvements were achieved for the alignment of shoulder, head, hip, and lower limbs, in addition to decrease in kyphosis and head protrusion. Conclusion: Patients with DS demonstrated satisfactory changes in motor behavior reflected in improved static posture after treatment with hippotherapy.

Hippotherapy: Remuneration issues impair the offering of this therapeutic strategy at Southern California rehabilitation centers

BACKGROUND

Hippotherapy is the use of equine movement in physical, occupational, or speech therapy in order to obtain functional improvements in patients. Studies show improvement in motor function and sensory processing for patients with a variety of neuromuscular disabilities, developmental disorders, or skeletal impairments as a result of using hippotherapy.

OBJECTIVE

The primary objective of this study is to identify the pervasiveness of hippotherapy in Southern California, and any factors that impair its utilization.

METHODS

One hundred and fifty-two rehabilitation centers in the Southern California counties of Los Angeles, San Diego, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo, Santa Barbara, Ventura, and Kern County were identified, and surveyed to ascertain if hippotherapy is utilized, and if not, why not.

RESULTS

Through a review of forty facilities that responded to our inquiry, our study indicates that the majority of rehabilitation centers are familiar with hippotherapy, however, only seven have reported that hippotherapy is indeed available as an option in therapy at their centers.

CONCLUSION

It is concluded that hippotherapy, used in a broad based array of physical and sensory disorders, is limited in its ability to be utilized, primarily due to remuneration issues.

A systematic review of evidence-based assessment practices by allied health practitioners for children with cerebral palsy

AIM

The routine use of psychometrically robust assessment tools is integral to best practice. This systematic review aims to determine the extent to which evidence-based assessment tools were used by allied health practitioners for children with cerebral palsy (CP).

METHOD

The Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocols 2015 was employed. A search strategy applied the free text terms: 'allied health practitioner', 'assessment', and 'cerebral palsy', and related subject headings to seven databases. Included articles reported assessment practices of occupational therapists, physiotherapists, or speech pathologists working with children with CP aged 0 to 18 years, published from the year 2000.

RESULTS

Fourteen articles met the inclusion criteria. Eighty-eight assessment tools were reported, of which 23 were in high use. Of these, three tools focused on gross motor function and had acceptable validity for use with children with CP: Gross Motor Function Measure, Gross Motor Function Classification System, and goniometry. Validated tools to assess other activity components, participation, quality of life, and pain were used infrequently or not at all.

INTERPRETATION

Allied health practitioners used only a few of the available evidence-based assessment tools. Assessment findings in many areas considered important by children and families were rarely documented using validated assessment tools.

What is hippotherapy? The indications and effectiveness of hippotherapy

Hippotherapy is a form of physical, occupational and speech therapy in which a therapist uses the characteristic movements of a horse to provide carefully graded motor and sensory input. A foundation is established to improve neurological function and sensory processing, which can be generalized to a wide range of daily activities. Unlike therapeutic horseback riding (where specific riding skills are taught), the movement of the horse is a means to a treatment goal when utilizing hippotherapy as a treatment strategy. Hippotherapy has been used to treat patients with neurological or other disabilities, such as autism, cerebral palsy, arthritis, multiple sclerosis, head injury, stroke, spinal cord injury, behavioral disorders and psychiatric disorders. The effectiveness of hippotherapy for many of these indications is unclear, and more research has been needed. Here, we purpose to give information about hippotherapy which is not known adequately by many clinicians and health workers.

Effects of horse-riding exercise on balance, gait, and activities of daily living in stroke patients

[Purpose] This study aimed to investigate the effects of horse-riding exercise on balance, gait, and activities of daily living (ADLs) in stroke patients. [Subjects] Among 20 participants with stroke, 10 were randomly assigned to the experimental group, and 10 were randomly assigned to the control group. The experimental group participated in horse-riding exercise for 30 minutes per day, 5 days a week for 6 weeks. Balance was tested with the Berg Balance Scale (BBS). Gait was measured using the 10-Meter Walk Test (10MWT). ADLs were tested with the Modified Barthel Index (MBI). Differences between pre- and post-experiment values within the two groups were compared using paired t-tests. Between-group differences were compared using independent t-tests. [Results] The experimental group showed significant improvements in balance, gait, and ADLs following horse-riding exercise. Additionally, the experimental group showed significant differences in balance, gait, and ADLs compared with in the control group. [Conclusion] These results support that horse-riding exercise enhances balance, gait, and ADLs in stroke patients. This study supports the need for further research on horse-riding exercise programs.

Hippotherapy as a treatment for socialization after sexual abuse and emotional stress

[Purpose] Hippotherapy is a therapeutic resource that uses the horse as a kinesiotherapy instrument to elicit motor and cognitive improvements in individuals with special needs. [Subjects and Methods] This research evaluated two women aged 18 and 21 years, who had suffered sexual violence when they were children between the ages of 6 and 7 years old. The subjects did not have mental dysfunction but they were regular students registered at a school of special education. The patients presented severe motor limitation, difficulty with coordination, significant muscular retractions, thoracic and cervical kyphosis, cervical protrusion wich was basically a function of the postures they had adopted when victims of the sexual violence suffered in childhood. The patients performed twenty sessions of 30 minutes of hippotherapy on a horse. The activities were structured to stimulate coordination, proprioception, the vestibular and motor-sensorial systems for the improvement of posture, muscle activity and cognition. [Results] The activities provided during the hippotherapy sessions elicited alterations in postural adjustment resulting in 30% improvement, 80% improvement in coordination in, 50% improvement in corporal balance and in sociability and self-esteem. [Conclusion] Hippotherapy proved to be an effective treatment method for coordination, balance and postural correction, and also improved the patients’ self-esteem that had suffered serious emotional stress.

Human pelvis motions when walking and when riding a therapeutic horse

A prevailing rationale for equine assisted therapies is that the motion of a horse can provide sensory stimulus and movement patterns that mimic those of natural human activities such as walking. The purpose of this study was to quantitatively measure and compare human pelvis motions when walking to those when riding a horse. Six able-bodied children (inexperienced riders, 8-12years old) participated in over-ground trials of self-paced walking and leader-paced riding on four different horses. Five kinematic measures were extracted from three-dimensional pelvis motion data: anteroposterior, superoinferior, and mediolateral translations, list angle about the anteroposterior axis, and twist angle about the superoinferior axis. There was generally as much or more variability in motion range observed between riding on the different horses as between riding and walking. Pelvis trajectories exhibited many similar features between walking and riding, including distorted lemniscate patterns in the transverse and frontal planes. In the sagittal plane the pelvis trajectory during walking exhibited a somewhat circular pattern whereas during riding it exhibited a more diagonal pattern. This study shows that riding on a horse can generate movement patterns in the human pelvis that emulate many, but not all, characteristics of those during natural walking.

The effects of horseback riding participation on the muscle tone and range of motion for children with spastic cerebral palsy

The objective of this research is to verify the effects of horseback riding participation on the muscle tone of pelvic limbs and articular range of motion for children with spastic cerebral palsy. The research target is 16 children with spastic cerebral palsy, 8 children for the experimental group and 8 children for the control group. As a tool to measure the muscle tone, Modified Ashworth Scale (MAS), was used and a goniometer was used to measure the range of motion (ROM). A therapeutic horseback riding program was conducted to an experimental group of 8 children with spastic cerebral palsy in the therapeutic horseback riding for 60 min a day, 2 days a week and a total of 12 weeks. The results are as follows: First, the participation in the therapeutic horseback riding program showed a statistically significant difference in the muscle tone for the knee of children with spastic cerebral palsy (P< 0.01). Second, though the difference in knee muscle tone between the experimental group and the control group was statistically insignificant, the average was improved by the participation. Third, the participation in the therapeutic horseback riding program showed a statistically significant difference in the hip-joint motion range for the knee of children with spastic cerebral palsy (P< 0.01). Fourth, though the difference in the hip joint motion range between the experimental group and the control group was statistically insignificant, the average was improved by the participation.

Comparison between the Effects of Horseback Riding Exercise and Trunk Stability Exercise on the Balance of Normal Adults

[Purpose] The aim of this study was to compare the effects of horseback riding exercise and trunk stability exercise on static and dynamic balance in normal adults. [Subjects and Methods] Twenty-two normal adults residing in communities were randomly divided into a horseback riding exercise group and a trunk stability exercise group, and they conducted exercise for eight weeks. [Results] Sway times of the COG (center of gravity) decreased significantly, and the A-P (anterior-posterior) and M-L (medial-lateral) velocities significantly decreased in both groups. A comparison of sway times of the COG after the intervention between the two groups revealed that the horseback riding exercise group showed larger decreases than the trunk stability exercise group. [Conclusion] In terms of the musculoskeletal factor, horseback riding may result in functional improvement and increased stability, and it may stimulate proprioceptive sense input in neurological terms. It is therefore considered a composite exercise method that may strengthen the two factors simultaneously.

The effects of hippotherapy on elderly persons' static balance and gait

[Purpose] The aim of this study was to examine the effects of hippotherapy on elderly persons’ static balance and gait. [Subjects and Methods] Twenty-two elderly persons residing in the community were randomly divided into a hippotherapy group and a treadmill group and they conducted exercise for eight weeks. [Results] Step lengths increased significantly, and step time and sway path lengths significantly decreased in both groups. A comparison of sway path lengths after the intervention between the two groups revealed that the hippotherapy group showed larger decreases than the treadmill group. [Conclusion] The results of this study indicate that hippotherapy may improve the static balance and gait of elderly persons residing in the community.

Perceptions of equine-assisted activities and therapies by parents and children with spinal muscular atrophy

PURPOSE

To identify the physical and psychosocial effects of equine-assisted activities and therapies (EAATs) on children with spinal muscular atrophy (SMA) from the perspective of the children and their parents.

METHODS

The families of all eligible children with SMA, who reported participation in EAAT, from a Western metropolitan academic center were contacted and invited to participate. This study implemented qualitative, semistructured interviews of children with SMA and their parents.

RESULTS

Three themes emerged from the qualitative content analysis: physical/psychosocial benefits; relationship development with the horses, instructors, and children; and barriers to continued EAAT engagement.

CONCLUSIONS

The data suggest that the overall EAAT experience was a source of enjoyment, self-confidence, and normalcy for the children with SMA. The results of this study provide preliminary support for the use of EAAT among children with SMA.

Effects of the horse riding simulator and ball exercises on balance of the elderly

[Purpose] The aim of this study was to examine the effects of horse riding exercise using a horse riding simulator (HRS) and a ball on static and dynamic balance of elderly people. [Methods] Thirty-two elderly people hospitalized in geriatric hospitals were randomly assigned to the HRS exercise group or the ball exercise groups, and they performed exercise for eight weeks. [Results] The length of postural sway during quite standing with and without eyes closed significantly decreased in both groups after the exercises and there was no significant difference between both groups in the Romberg test. In the functional reach test (FRT), there were significant increases in distance in both groups after the exercises, and the distance of the HRS exercise group was significantly greater than that of the ball exercise group. In the Timed Up & Go test (TUG) and Timed 10-meter walk test (10MWT), the time significantly decreased in both groups, and there was a more significant decrease in the HRS exercise group than in the ball exercise group. [Conclusion] The results of this study indicate that HRS and ball exercises may improve the balance and gait ability of elderly people hospitalized in nursing homes or geriatric hospitals.

Hypothalamic-pituitary-adrenal axis responses of horses to therapeutic riding program: effects of different riders

In order to determine whether therapeutic riding could result in higher levels of stress than recreational riding, hypothalamic-pituitary-adrenal (HPA) axis response was evaluated in six horses by monitoring circulating β-endorphin, ACTH and cortisol concentrations. Horses were already accustomed to be trained both for therapy and riding school activity since 2004. Intervention consisted of 60-minute therapeutic sessions, two times per week for 6weeks with different riders: disabled and recreational riders (session A and B respectively). The therapeutic riders' group (A) consisted of six children with psychomotor disabilities; the recreational riders' group (B) consisted of six healthy children without any previous horse riding experience. Horses were asked to perform the same gaits and exercises at all sessions, both with disabled and healthy users. The statistical analysis showed that during both sessions the mean basal β-endorphin and ACTH levels of horses did not show any significant changes, while the one way RM-ANOVA showed significant effects of sessions A on the cortisol (F=11.50; P<0.01) levels. Horses submitted to sessions A showed lower cortisol levels both at 5min (P<0.001) and at 30min (P<0.005) after therapeutic sessions than those after session B. Results suggest that in tested horses and for the variables settled, HPA axis was less responsive to disabled than healthy, recreational riders. Among the endocrine responses, cortisol was one of the indicators of HPA axis stress response.

Study of the therapeutic effects of a hippotherapy simulator in children with cerebral palsy: a stratified single-blind randomized controlled trial

OBJECTIVE

To investigate whether hippotherapy (when applied by a simulator) improves postural control and balance in children with cerebral palsy.

DESIGN

Stratified single-blind randomized controlled trial with an independent assessor. Stratification was made by gross motor function classification system levels, and allocation was concealed.

SUBJECTS

Children between 4 and 18 years old with cerebral palsy.

INTERVENTIONS

Participants were randomized to an intervention (simulator ON) or control (simulator OFF) group after getting informed consent. Treatment was provided once a week (15 minutes) for 10 weeks.

MAIN MEASURES

Gross Motor Function Measure (dimension B for balance and the Total Score) and Sitting Assessment Scale were carried out at baseline (prior to randomization), end of intervention and 12 weeks after completing the intervention.

RESULTS

Thirty-eight children participated. The groups were balanced at baseline. Sitting balance (measured by dimension B of the Gross Motor Function Measure) improved significantly in the treatment group (effect size = 0.36; 95% CI 0.01-0.71) and the effect size was greater in the severely disabled group (effect size = 0.80; 95% CI 0.13-1.47). The improvements in sitting balance were not maintained over the follow-up period. Changes in the total score of the Gross Motor Function Measure and the Sitting Assessment Scale were not significant.

CONCLUSION

Hippotherapy with a simulator can improve sitting balance in cerebral palsy children who have higher levels of disability. However, this did not lead to a change in the overall function of these children (Gross Motor Function Classification System level V).

Use of hippotherapy in gait training for hemiparetic post-stroke

OBJECTIVE

To evaluate the hippotherapy influence on gait training in post-stroke hemiparetic individuals.

METHOD

The study was constituted of 20 individuals divided into two groups. Group A performed the conventional treatment while group B the conventional treatment along with hippotherapy during 16 weeks. The patients were evaluated by using the Functional Ambulation Category Scale, Fugl-Meyer Scale, only the lower limbs and balance sub items, Berg Balance Scale, and functional assessment of gait (cadence) in the beginning and end of the treatment.

RESULTS

Significant improvements were observed in the experimental group including motor impairment in lower limbs (p=0.004), balance, over time (p=0.007) but a significant trend between groups (p=0.056). The gait independence, cadence and speed were not significantly in both groups (p=0.93, 0.69 and 0.44).

CONCLUSION

Hippotherapy associated with conventional physical therapy demonstrates a positive influence in gait training, besides bringing the patients' gait standard closer to normality than the control group.

Effects of hippotherapy and therapeutic horseback riding on postural control or balance in children with cerebral palsy: a meta-analysis

AIM

This research review and meta-analysis presents an overview of the effects of hippotherapy and therapeutic horseback riding (THR) on postural control or balance in children with cerebral palsy (CP).

METHOD

To synthesize previous research findings, a systematic review and meta-analysis were undertaken. Relevant studies were identified by systematic searches of multiple online databases from the inception of the database through to May 2010. Studies were included if they fulfilled the following criteria: (1) quantitative study design, (2) investigation of the effect of hippotherapy or THR on postural control or balance, and (3) the study group comprised children and adults with CP. The selected articles were rated for methodological quality. The treatment effect was coded as a dichotomous outcome (positive effect or no effect) and quantified by odds ratio (OR). The pooled treatment effect was calculated using a random-effects model. Meta-regression of the effect size was performed against study covariates, including study size, publication date, and methodological quality score.

RESULTS

From 77 identified studies, 10 met the inclusion criteria. Two were excluded because they did not include a comparison group. Therapy was found to be effective in 76 out of 84 children with CP included in the intervention groups. The comparison groups comprised 89 children: 50 non-disabled and 39 with CP. A positive effect was shown in 21 of the children with CP in the comparison group regardless of the activity undertaken (i.e. physiotherapy, occupational therapy, sitting on a barrel or in an artificial saddle). The pooled effect size estimate was positive (OR 25.41, 95% CI 4.35, 148.53), demonstrating a statistically significant effectiveness of hippotherapy or THR in children with CP (p<0.001). Meta-regression of study characteristics revealed no study-specific factors.

INTERPRETATION

The eight studies found that postural control and balance were improved during hippotherapy and THR. Although the generalization of our findings may be restricted by the relatively small sample size, the results clearly demonstrate that riding therapy is indicated to improve postural control and balance in children with CP.

Outcome measures of activity for children with cerebral palsy: a systematic review

PURPOSE

The purpose of this systematic review was to identify valid, reliable, and clinically practical measures of function/activity for children with cerebral palsy.

METHOD

Cochrane, MEDLINE, CINAHL, AMED, PEDro, and ScienceDirect were searched to identify relevant studies. Reference lists were hand-searched, and databases were searched specifically for outcome measures (OMs) identified. Studies were examined for bias based on published recommendations.

RESULTS

Seven studies on 6 OMs were included, which were of moderate or good methodological quality.

CONCLUSIONS

Most measures require further research to fully establish their psychometric properties. Only the Gross Motor Function Measure versions 88 and 66 and the Pediatric Evaluation of Disability Inventory were identified as potentially appropriate for this client group, but not all are valid for children of all ages and Gross Motor Function Classification System levels. The clinical application of these OMs is discussed in relation to capacity, capability, or performance; new developments are highlighted.

Study of the therapeutic effects of an advanced hippotherapy simulator in children with cerebral palsy: a randomised controlled trial

Background

Although hippotherapy treatment has been demonstrated to have therapeutic effects on children with cerebral palsy, the samples used in research studies have been very small. In the case of hippotherapy simulators, there are no studies that either recommend or advise against their use in the treatment of children with cerebral palsy. The aim of this randomised clinical study is to analyse the therapeutic effects or the contraindications of the use of a commercial hippotherapy simulator on several important factors relating to children with cerebral palsy such as their motor development, balance control in the sitting posture, hip abduction range of motion and electromyographic activity of adductor musculature.

Methods/Design

The study is a randomised controlled trial. It will be carried out with a sample of 37 children with cerebral palsy divided into two treatment groups. Eligible participants will be randomly allocated to receive either (a) Treatment Group with hippotherapy simulator, maintaining sitting posture, with legs in abduction and rhythmic movement of the simulator or (b) Treatment Group maintaining sitting posture, with legs in abduction and without rhythmic movement of the simulator. Data collection and analysis: all measurements will be carried out by a specially trained blind assessor. To ensure standardization quality of the assessors, an inter-examiner agreement will be worked out at the start of the study. The trial is funded by the Department of Research, Innovation and Development of the Regional Government of Aragon (Official Bulletin of Aragon 23 July 2007), project number PM059/2007.

Discussion

Interest in this project is due to the following factors: Clinical originality (there are no previous studies analysing the effect of simulators on the population group of children with CP, nor any studies using as many variables as this project); Clinical impact (infantile cerebral palsy is a chronic multisystemic condition that affects not only the patient but also the patient's family and their close circle of friends); Practical benefits (the development of an effective treatment is very important for introducing this element into the rehabilitation of these children).

The Effect of Hippotherapy on Spasticity and on Mental Well-Being of Persons With Spinal Cord Injury

OBJECTIVES

To determine the effect of hippotherapy on spasticity and on mental well-being of persons with spinal cord injury (SCI), and to compare it with the effects of other interventions.

DESIGN

Crossover trial with 4 conditions.

SETTING

Swiss paraplegic center.

PARTICIPANTS

A volunteer sample of 12 people with spastic SCI (American Spinal Injury Association grade A or B).

INTERVENTIONS

Hippotherapy, sitting astride a Bobath roll, and sitting on a stool with rocking seat. Each session lasted 25 minutes and was conducted twice weekly for 4 weeks; the control condition was spasticity measurement without intervention.

MAIN OUTCOME MEASURES

Clinical rating by a blinded examiner of movement-provoked muscle resistance, using the Ashworth Scale; self-rating of spasticity by subjects on a visual analog scale (VAS); and mental well-being evaluated with the self-rated well-being scale Befindlichkeits-Skala of von Zerssen. Assessments were performed immediately after intervention sessions (short-term effect); data from the assessments were analyzed 3 to 4 days after the sessions to calculate the long-term effect.

RESULTS

By analyzing the clinically rated spasticity, only the effect of hippotherapy reached significance compared with the control condition (without intervention); median differences in the Ashworth scores' sum before and after hippotherapy sessions ranged between -8.0 and +0.5. There was a significant difference between the spasticity-reducing effect of hippotherapy and the other 2 interventions in self-rated spasticity by VAS; median differences of the VAS before and after hippotherapy sessions ranged between -4.6 and +0.05cm. There were no long-term effects on spasticity. Immediate improvements in the subjects' mental well-being were detected only after hippotherapy (P=.048).

CONCLUSIONS

Hippotherapy is more efficient than sitting astride a Bobath roll or on a rocking seat in reducing spasticity temporarily. Hippotherapy had a positive short-term effect on subjects' mental well-being.
