Topic:Motor Function
Motor function in horses refers to the complex coordination of muscular and neural activities that enable movement and physical activity. It involves the integration of signals from the central and peripheral nervous systems to facilitate locomotion, balance, and posture. Motor function is essential for various equine activities, including walking, trotting, galloping, and performing athletic tasks. Factors influencing motor function include neurological health, musculoskeletal integrity, and the horse's overall physical condition. This page compiles peer-reviewed research studies and scholarly articles that explore the mechanisms, assessment, and implications of motor function in equine health and performance.
Hippotherapy effects on trunk, pelvic, and hip motion during ambulation in children with neurological impairments. This study investigated the effects of a 10-week hippotherapy program on trunk, pelvis, and hip joint positioning during the stance phase of gait. Methods: Eleven children (6 boys and 5 girls; 7.9 ± 2.7 years) with neurological disorders and impaired ambulation participated. Joint range of motion data were collected via 3-dimensional computerized gait analysis before and after the program. Paired t tests were performed on kinematic data for each joint. Results: Significant improvements (P ≤ .008) and large effect sizes (ESs) for sagittal plane hip positions at initial contact and toe-off we...
Systematic review and meta-analysis of the effect of equine assisted activities and therapies on gross motor outcome in children with cerebral palsy. To evaluate the literature on the efficacy of equine assisted activities and therapies (EAAT) on gross motor outcomes representing the ICF component of body functions and activity in children with cerebral palsy (CP). Methods: We conducted a systematic review and meta-analysis of randomized controlled trials and observational studies of hippotherapy (HPOT) and therapeutic horseback riding (TR) for children with spastic CP. Gross motor outcomes, assessed via muscle activity and muscle tone, gait, posture and Gross Motor Function Measures (GMFM) were evaluated. Results: Five TR studies and nine ...
Differences in motor imagery time when predicting task duration in alpine skiers and equestrian riders. Athletes' ability to use motor imagery (MI) to predict the speed at which they could perform a motor sequence has received little attention. In this study, 21 alpine skiers and 16 equestrian riders performed MI based on a prediction of actual performance time (a) after the course inspection, (b) before the start, and (c) after the actual performance. MI and physical times were similar in expert skiers during each imagery session, while novice skiers and novice and expert riders underestimated the actual course duration. These findings provide evidence that the temporal accuracy of an imagery t...
Therapeutic effects of a horse riding simulator in children with cerebral palsy. To evaluate the efficacy of horse ridding simulator on the sitting postural control of children with spastic diplegia. Methods: Forty children were randomly divided in a group using the simulator (RS) and a group performing conventional physical therapy (CT). FScan/Fmat equipment was used to register maximal displacement in antero-posterior (AP) and medio-lateral (ML) directions with children in sitting position. At the pre and post intervention stage both groups were classified according to the Gross Motor Function Classification System (GMFCS) and, after intervention, by the AUQEI questionna...
Quantifying show jumping horse rider expertise using IMUs. Horse rider ability has long been measured using horse performance, competition results and visual observation. Scientific methods of measuring rider ability on the flat are emerging such as measuring position angles and harmony of the horse-rider system. To date no research has quantified rider ability in show jumping. Kinematic analysis and motion sensors have been used in sports other than show jumping to measure the quality of motor control patterns in humans. The aim of this study was to quantify rider ability in show jumping using body-mounted IMUs. Preliminary results indicate that ther...
Circadian regulation of locomotor activity and skeletal muscle gene expression in the horse. Circadian rhythms are innate 24-h cycles in behavioral and biochemical processes that permit physiological anticipation of daily environmental changes. Elucidating the relationship between activity rhythms and circadian patterns of gene expression may contribute to improved human and equine athletic performance. Six healthy, untrained mares were studied to determine whether locomotor activity behavior and skeletal muscle gene expression reflect endogenous circadian regulation. Activity was recorded for three consecutive 48-h periods: as a group at pasture (P), and individually stabled under a ...
Study of the therapeutic effects of an advanced hippotherapy simulator in children with cerebral palsy: a randomised controlled trial. 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...
Changes in trunk and head stability in children with cerebral palsy after hippotherapy: a pilot study. Hippotherapy (HPOT) is a therapy that uses horse movement. This pilot investigation objectively evaluated the efficacy of HPOT in improving head/trunk stability in children with cerebral palsy (CP). The participants were six children with spastic diplegia and six children without disability. Head and trunk stability was challenged by using a motorized barrel and measured by a video motion capture system before and after a 12-week intervention of 45 min of HPOT a week. The variables measured were anterior-posterior (AP) translation of the head, and spine at five points and average AP head angle...
Changes in dynamic trunk/head stability and functional reach after hippotherapy. To determine if hippotherapy (therapy using a horse) improves head/trunk stability and upper extremity (UE) reaching/targeting in children with spastic diplegia cerebral palsy (SDCP). 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...
Effects of hippotherapy on people with cerebral palsy from the users’ perspective: a qualitative study. Although there is now some evidence for specific effects of hippotherapy on people with cerebral palsy, these studies fail to provide a comprehensive picture of the effects of hippotherapy. This was the first qualitative study to explore the hippotherapy experience of people with cerebral palsy from a user perspective. The effects of hippotherapy and their context were of particular interest. Seventeen users aged from 4 to 63, with or without their parents, participated in focus groups or individual interviews in six centres in Britain and in Germany. The main effects of hippotherapy, as ident...
Horses do not exhibit motor bias when their balance is challenged. In many equestrian pursuits such as dressage and show-jumping, it is important that the horse exhibits the same level of balance when ridden to the left as when ridden to the right in canter - that is, to show no motor bias. It is a long-held belief within such disciplines that to reduce bias that exists in horses and thus to enhance symmetry of performance to the left and right, the horse needs to be worked equally in both directions, although there is a lack of scientific evidence of this influencing bias. There also is little compelling evidence for either the existence or absence of motor ...
The effect of hippotherapy on functional outcomes for children with disabilities: a pilot study. The purpose of this study was to measure the effect of hippotherapy on functional outcomes using the Goal Attainment Scale (GAS) for children with physical disabilities. Methods: Participants included 4 children aged 5 to 9 years with physical impairments and/or documented motor delays. Individual measurable objectives were developed using the GAS for each child. Data were collected on each child every other week throughout the baseline and intervention phase over 1 year using a multiple single case experimental A-B design. Results: Three of the 4 children had a significant improvement in func...

Sportverletzung Sportschaden : Organ der Gesellschaft fur Orthopadisch-Traumatologische Sportmedizin
The assessment of body posture control can be time consuming and cumbersome due to the complexity and the multimodal influence of a multiply influenced system. Various types of equine paces, such as stepping, trotting or galloping, result in acceleration and deceleration forces of different magnitude. These forces induce, in the horseman, reflexes that mediate motor activity to sustain posture balance and counterbalance the gravitational pull. However, there is a paucity of real life data regarding the extent of the various postural subsystems that are recruited to control postural balance in ... Facial hair whorls (trichoglyphs) and the incidence of motor laterality in the horse. Several species demonstrate obvious motor laterality (sidedness, handedness) in their motor function. Motor laterality in the horse affects locomotion and subsequently equine performance during training and may have inherent safety implications for equitation. Some of the most commonly used identification features in the horse are hair whorls (trichoglyphs), since their specific location and character vary to some degree in every horse. We investigated the relationship between the hair flow of single facial hair whorls and the incidence of lateralised motor bias in 219 horses when under saddle...
The effect of hippotherapy on postural control in sitting for children with cerebral palsy. The purpose of this single subject research study was to examine the effects of a once weekly, 10-week hippotherapy program for three children, ages 27-54 months, with cerebral palsy. Participants were rated as Level V on the Gross Motor Function Classification System. The Sitting Dimension of the Gross Motor Function Measure was used to establish a baseline of sitting abilities, and was administered every 2 weeks during intervention. The Sitting Assessment Scale and the Gross Motor Function Measure were administered before, after, and 4 weeks postintervention. Parental perceptions of the hipp...
Masticatory motor patterns in ungulates: a quantitative assessment of jaw-muscle coordination in goats, alpacas and horses. We investigated patterns of jaw-muscle coordination during rhythmic mastication in three species of ungulates displaying the marked transverse jaw movements typical of many large mammalian herbivores. In order to quantify consistent motor patterns during chewing, electromyograms were recorded from the superficial masseter, deep masseter, posterior temporalis and medial pterygoid muscles of goats, alpacas and horses. Timing differences between muscle pairs were evaluated in the context of an evolutionary model of jaw-muscle function. In this model, the closing and food reduction phases of masti...
Does horseback riding therapy or therapist-directed hippotherapy rehabilitate children with cerebral palsy? Quantitative (not qualitative) studies were sought investigating whether horseback riding used as therapy improves gross motor function in children with cerebral palsy (CP). Eleven published studies on instructor-directed, recreational horseback riding therapy (HBRT) and licensed-therapist-directed hippotherapy were identified, reviewed, and summarized for research design, methodological quality, therapy regimen, internal/external validity, results, and authors'conclusions. Methodological quality was moderate to good for all studies; some studies were limited by small sample size or lack of no...
Influence of detomidine and buprenorphine on motor-evoked potentials in horses. Horses need to be sedated before they are investigated by transcranial magnetic stimulation because of the mild discomfort induced by the evoked muscle contraction and the noise of stimulation. This paper describes the influence of a combination of detomidine (10 microg/kg bodyweight) and a low dose of buprenorphine (2.4 microg/kg) on the onset latency and peak-to-peak amplitude of magnetic motor-evoked potentials in normal horses. There were no significant differences between measurements of these parameters made before the horses were sedated and measurements made 10 and 30 minutes after the...
[Advantages of ride therapy in different forms of infantile cerebral palsy (therapeutic riding)]. One hundred children with cerebral palsy, aged 3-14 years, were divided into two equal groups, the first one including 50 children assigned to ride therapy and the second one--to Bobath therapeutic gymnastics. All the patients underwent a functional examination, which was rated using score system worked out by the authors, thus enabling a quantitative evaluation of treatment efficacy. In all the cases, physical rehabilitation resulted in a positive but not the same effect, with ride therapy being significantly (p < 0.001) more beneficial treatment compared to therapeutic gymnastics. Ride thera...

Horseback riding in children with cerebral palsy: effect on gross motor function. The effects of recreational horseback riding therapy (HBRT) on gross motor function in children with cerebral palsy (CP: spastic diplegia, spastic quadriplegia, and spastic hemiplegia) were determined in a blinded study using the Gross Motor Function Measure (GMFM). Seventeen participants (nine females, eight males; mean age 9 years 10 months, SE 10 months) served as their own control. Their mean Gross Motor Function Classification System score was 2.7 (SD 0.4; range 1 to 5). HBRT was 1 hour per week for three riding sessions of 6 weeks per session (18 weeks). GMFM was determined every 6 weeks...
Ankle-foot orthoses: effect on gait in children with cerebral palsy. In this study our aim was to evaluate the effectiveness of Ankle-Foot Orthoses (AFOs) on gait function in patients with spastic cerebral palsy for whom orthoses were indicated to control dynamic equines deformity. Methods: Twenty-four spastic cerebral palsied patients with dynamic equines deformity were included in the study. Videotape recordings were performed to each patient on the same day with barefoot and AFOs. Temporal distance factors including velocity, cadence, stride length, stride width and Clinical Gait Assessment Score (CGAS) were compared across two conditions. Results: The use o...
Effect of an equine-movement therapy program on gait, energy expenditure, and motor function in children with spastic cerebral palsy: a pilot study. The purpose of this study was to evaluate the effects of an 8-week program of hippotherapy on energy expenditure during walking; on the gait dimensions of stride length, velocity, and cadence; and on performance on the Gross Motor Function Measure (GMFM) in five children with spastic cerebral palsy (CP). A repeated-measures within-subjects design was used consisting of two baseline measurements taken 8 weeks apart, followed by an 8-week intervention period, then a posttest. After hippotherapy, all five children showed a significant decrease (X2(r)=7.6, P<0.05) in energy expenditure during walk...
Light microscopy of the enteric nervous system of horses with or without equine dysautonomia (grass sickness): its correlation with the motor effects of physostigmine. Light microscopy was undertaken on sections from the caudal flexure of the duodenum and the terminal ileum proximal to the ileocaecal fold in 5 control horses, 5 horses with acute grass sickness (AGS), and 5 horses with chronic grass sickness (CGS). With the exception of the ileal submucous plexus of the CGS group, the AGS group had the lowest number of neurons as measured using a subjective scoring scheme. The proportion of abnormal neurons in the AGS group was similar in both plexuses and both regions, whereas the values for the CGS group were much higher in the duodenal region than in the i...
[Use of a mix of lidocaine and butorphanol as a caudal epidural anesthesia in a mare]. Loss of rear motor control is the main limiting factor in the use of caudal epidural anesthesia in the horse. In man and laboratory animals, a small dose of an opiate combined with a local anesthetic enhances analgesia without impairing motor function. Thus, the amount of local anesthetic administered may be reduced. Butorphanol is an opiate widely used in horses. It has a good margin of safety and few cardiorespiratory effects. The effects of lidocaine (0.25 mg/kg) and lidocaine-butorphanol (0.25 mg/kg, and 0.04 mg/kg, respectively) were compared in 2 groups of 5 healthy unsedated mares. Hors...
Magnetic motor evoked potentials in ponies. Magnetic stimulation of motor pathways was used to effect motor unit action potential recordings from forelimb and hindlimb muscles in unanesthetized ponies. Motor pathway conduction velocities to the forelimb and hindlimb were determined to be 53.8 +/- 9.6 m/s-1 and 63.4 +/- 8.3 m/s-1, respectively. This noninvasive technique will enable more precise evaluation of motor deficits in clinical patients than is possible with the neurological examination.
