Topic:Back Pain
Back pain in horses is a condition that can affect the animal's performance, behavior, and overall well-being. It can result from a variety of causes, including musculoskeletal disorders, poor saddle fit, or underlying medical conditions. The diagnosis of back pain in horses often involves a combination of clinical examination, imaging techniques such as radiography or ultrasound, and sometimes diagnostic analgesia. Treatment approaches can vary depending on the underlying cause and may include physical therapy, medication, or adjustments in management practices. This page compiles peer-reviewed research studies and scholarly articles that explore the causes, diagnostic methods, and treatment options for back pain in horses, providing insights into its impact on equine health and performance.
Complementary and alternative medicine for the management of orthopaedic problems in Swiss Warmblood horses. It appears that complementary and alternative medicine (CAM) is used increasingly often in horses for the assessment and treatment of suspected orthopaedic problems, especially back problems. The aim of this study was to determine the frequency of CAM use for the management of orthopaedic problems in a defined population of Swiss Warmblood horses. A total of 239 owners and caretakers of horses from a pre-defined database were called by a veterinarian to participate in the survey. A standardized questionnaire was designed to determine, for each orthopaedic case, where the localization of the pr...
Algometry to measure pain threshold in the horse’s back – An in vivo and in vitro study. The aim of this study was to provide information on algometric transmission of pressure through the dorsal thoracolumbar tissues of the equine back. Using a commercially available algometer, measurements were carried out with six different tips (hemispheric and cylindrical surfaces, contact areas 0.5 cm2, 1 cm2, and 2 cm2). In nine live horses the threshold of pressure that lead to any reaction was documented. In postmortem specimens of five euthanized horses the transmission of algometer pressure onto a pressure sensor placed underneath the dorsal thoracolumbar tissues at the level of the ...
Structure and Innervation of the Equine Supraspinous and Interspinous Ligaments. Pain related to the osseous thoracolumbar spine is common in the equine athlete, with minimal information available regarding soft tissue pathology. The aims of this study were to describe the anatomy of the equine SSL and ISL (supraspinous and interspinous ligaments) in detail and to assess the innervation of the ligaments and their myofascial attachments including the thoracolumbar fascia. Ten equine thoracolumbar spines (T15-L1) were dissected to define structure and anatomy of the SSL, ISL and adjacent myofascial attachments. Morphological evaluation included histology, electron microscopy...
Whole-body vibration exposure of occupational horseback riding in agriculture: A ranching example. Horse riding is common in many occupations; however, there is currently no research evaluating exposure to whole-body vibration and mechanical shock on horseback. Methods: Whole-body vibration was measured on a cattle rancher during two 30 min horseback rides using a tri-axial accelerometer mounted on a western saddle. Vibration was summarized into standardized metrics, including the 8 hr equivalent root-mean-squared acceleration (A[8]) and the daily 4th power vibration dose value (VDV). The resulting exposures were compared to the exposure limit and action values provided by European Unio...
Effects of the rider on the kinematics of the equine spine under the saddle during the trot using inertial measurement units: Methodological study and preliminary results. Many factors associated with the saddle and the rider could produce pain in horses thus reducing performance. However, studies of horse-saddle-rider interactions are limited and determining their effects remains challenging. The aim of this study was to test a novel method for assessing equine thoracic and lumbar spinal movement under the saddle and collect data during trotting. Back movement was measured using inertial measurement units (n = 5) fixed at the levels of thoracic vertebrae T6, T12 and T16, and lumbar vertebrae L2 and L5. To compare unridden and ridden conditions, three horses...
Effects of X-ray Beam Angle and Geometric Distortion on Width of Equine Thoracolumbar Interspinous Spaces Using Radiography and Computed Tomography: A Cadaveric Study. The widths of spaces between the thoracolumbar processi spinosi (interspinous spaces) are frequently assessed using radiography in sports horses; however effects of varying X-ray beam angles and geometric distortion have not been previously described. The aim of this prospective, observational study was to determine whether X-ray beam angle has an effect on apparent widths of interspinous spaces. Thoracolumbar spine specimens were collected from six equine cadavers and left-right lateral radiographs and sagittal and dorsal reconstructed computed tomographic (CT) images were acquired. Sequentia...
Poor safety climate, long work hours, and musculoskeletal discomfort among Latino horse farm workers. This study investigated the prevalence of self-reported musculoskeletal discomfort (MSD) and work-related factors associated with elevated MSD among Latino thoroughbred farm workers. Participants (N = 225) were recruited using a community-based purposive sampling approach to participate in in-person interviews. Of these workers, 85% experienced MSD. MSD was divided into tertiles; the upper tertile was defined as elevated. Multivariable Poisson regression revealed associations between any elevated MSD and longer tenure on horse farms, longer work hours, and poor safety climate. Elevated neck/b...
Feasibility and safety of lumbosacral epiduroscopy in the standing horse. The large size of the adult horse prevents the use of advanced imaging modalities in most areas of the axial skeleton, including the lumbosacral vertebral column. Traditional imaging techniques are frequently unable to pinpoint the underlying pathology in horses with caudal back pain. In man, lumbosacral epiduroscopy is used to diagnose and treat subjects with chronic back and leg pain. This technique may close the diagnostic gap in horses with similar clinical signs. Objective: To evaluate the safety and feasibility of lumbosacral epiduroscopy in the standing adult horse. Methods: Descriptive...
Core Training and Rehabilitation in Horses. The central body axis or core is a key component in controlling body posture and providing a stable platform for limb movements and generation of locomotor forces. Persistent dysfunction of the deep stabilizing muscles seems to be common in horses indicating a need for core training exercises to restore normal function. Core training should be performed throughout the horse's athletic career to maintain a healthy back and used therapeutically when back pain is identified. This article reviews the structure and function of the equine thoracolumbar spine with special reference to function, dysfu...
Introduction to Equine Physical Therapy and Rehabilitation. Physical therapy (physiotherapy, or PT) can be broadly defined as the restoration of movement and function and includes assessment, treatment, and rehabilitation. This review outlines the history, definition, and regulation of PT, followed by the core scientific principles of PT. Because musculoskeletal physiotherapy is the predominant subdiscipline in equine PT, encompassing poor performance, back pain syndromes, other musculoskeletal disorders, and some neuromuscular disorders, the sciences of functional biomechanics, neuromotor control, and the sensorimotor system in the spine, pelvis, and ...
Effect of the rider position during rising trot on the horse׳s biomechanics (back and trunk kinematics and pressure under the saddle). Knowledge about the horse-saddle-rider interaction remains limited. The aim of this study was to compare the effect of the rider׳s position at rising trot on the pressure distribution, spine movements, stirrups forces and locomotion of the horse. The horse׳s back movements were measured using IMUs fixed at the levels of thoracic (T6, T12, T16) and lumbar (L2, L5) vertebrae, the pressure distribution using a pressure mat and stirrups forces using force sensors. The horse׳s and rider׳s approximated centres of mass (COM) were calculated using 2D reflective markers. To compare both trot phases...
Lower attention to daily environment: a novel cue for detecting chronic horses’ back pain? Chronic pain is thought to affect patients' cognitive functioning, including attention. Loss of attention is likely to have an impact on the execution of daily tasks, and, therefore, to have negative effects. However, relationships between chronic pain and cognitive deficits are still debated. Pre-clinical studies using laboratory animals prove useful to model pain-related cognitive impairment, but animal models had to predict effects in the real world. This study investigates attentional engagement of domestic horses by comparing observations in a home setting and evaluations of vertebral dis...
[Horse riding as a form of recreation and professional sport taking into account the spine mobility of riders – a preliminary results]. Horse riding becoming increasingly common and popular form of recreation and leisure activities. However, enforced, proper posture while riding a horse, may contribute to decrease mobility of spine and lead to occurrence back pain. Objective: The aim of this study was to assess the impact of the systematic training of horse riding on the global mobility of the spine and back pain prevalence in-training horse riders professionally and recreational. Methods: The study included 70 horse riders. The subjects were divided into two groups: 1) professional horse riders (n=50; 71.43%) or 2) a group of...
[Impact of Spinal Fractures in Horseback Riding].
Sportverletzung Sportschaden : Organ der Gesellschaft fur Orthopadisch-Traumatologische Sportmedizin
Injuries to the spinal cord are not only dreaded because of the high risks existing during the acute phase, but also because of their potential long-term sequelae. Horseback riding also poses a high risk of spinal injuries. We therefore evaluated the most frequent characteristics of accidents leading to long-term sequelae, the primary long-term discomfort resulting from such injuries caused by horseback riding accidents and the way injured persons changed their behaviour after the accidents. Methods: Our study included all cases of horseback riding injuries registered in the Department of Trau... An analytical ergonomic risk evaluation of body postures during daily cleaning tasks in horse stables. Musculoskeletal disorders (MSDs) are a common reason for health problems and sick leave in many professions. A work arena where MSDs have not been sufficiently studied is stable work. Here many heavy and repetitive work tasks are performed manually with old-fashioned working tools. Objective: The aim of this study was to use an analytical approach to identify, evaluate and grade ergonomic problems in physical work performed during daily activities in horse stables and relate these to MSDs among the workers and to the design of the tools. Methods: Three common work tasks were studied to identif...

Methods: Quantitative analysis of back movement and gait symmetry be...
Epiduroscopy of the lumbosacral vertebral canal in the horse: Technique and endoscopic anatomy. Back pain is a common cause of gait alterations and poor performance in horses, but the available imaging modalities are frequently insufficient to isolate the underlying pathology. In human patients, epidural endoscopy (epiduroscopy) is successfully used to diagnose and treat challenging cases of lower back pain. Endoscopy of the cervical epidural space has previously been reported in anaesthetised horses. Objective: To develop a technique for lumbosacral epiduroscopy in standing horses and to describe the endoscopic anatomy of the lumbosacral epidural space. Methods: Pilot study to assess th...
Preliminary data on the effect of osseous anatomy on ex vivo joint mobility in the equine thoracolumbar region. The thoracolumbar region is clinically important in horses; however, the link between joint mobility and bony joint morphology has not been tested quantitatively. Objective: To establish which aspects of vertebral morphology correlate with ex vivo range of motion in the thoracolumbar region of Equus caballus, and demonstrate methodologies for linking vertebral form and function. Methods: Morphometric study of osteological specimens. Methods: A digital model was created of a disarticulated thoracolumbar region to examine bone-to-bone interactions during in silico bending. Linear measurements a...
Determination of vertebral range of motion using inertial measurement units in 27 Franches-Montagnes stallions and comparison between conditions and with a mixed population. The diagnosis of equine back disorders is challenging. Objectively determining movement of the vertebral column may therefore be of value in a clinical setting. Objective: To establish whether surface-mounted inertial measurement units (IMUs) can be used to establish normal values for range of motion (ROM) of the vertebral column in a uniform population of horses trotting under different conditions. Methods: Vertebral ROM was established in Franches-Montagnes stallions and a general population of horses and the variability in measurements compared between the two groups. Repeatability and the ...
Saddles and girths: What is new? Several studies have shown that there is a high prevalence of ill-fitting saddles. Many riders do not have saddle fit professionally assessed on at least an annual basis. Back dimensions can change considerably over the period of a year and therefore saddle fit should be assessed several times yearly, especially if work intensity has been altered. Saddle fit should be evaluated before and after exercise because back dimensions can change during work. Ideally, horses should be ridden in individual purpose-fitted saddles, rather than the same saddle being used on several horses. There remains li...
A longitudinal study of back dimension changes over 1 year in sports horses. Major back dimension changes over time have been observed in some horses, the speed of which may be influenced by work type, skeletal maturity, nutrition and saddle fit. Currently, there are no longitudinal data quantifying changes in back dimensions. The objectives of this study were to quantify back dimension changes over time, to identify the effects of horse, saddle and rider on these dimensions, and to determine their association with season, weight, work and saddle management. A prospective, longitudinal study was performed, using stratified random sampling within a convenience sample of...
Posture, flexibility and grip strength in horse riders. Since the ability to train the horse to be ambidextrous is considered highly desirable, rider asymmetry is recognized as a negative trait. Acquired postural and functional asymmetry can originate from numerous anatomical regions, so it is difficult to suggest if any is developed due to riding. The aim of this study was therefore to assess symmetry of posture, strength and flexibility in a large population of riders and to determine whether typical traits exist due to riding. 127 right handed riders from the UK and USA were categorized according to years riding (in 20 year increments) and their...
Saddle fit and management: An investigation of the association with equine thoracolumbar asymmetries, horse and rider health. No previous studies have investigated interrelationships between saddle fit/management, equine thoracolumbar asymmetries, rider and horse health. Objective: To assess associations between data obtained by clinical assessment and those provided by riders via a questionnaire. Methods: Clinical assessment of a convenience sample of horses and riders compared with a Web-based questionnaire survey (n = 205). Methods: Horse thoracolumbar asymmetries at predetermined sites, the presence of lameness (in hand and/or ridden), saddle slip, saddle fit/management and rider straightness were assessed. Kappa...
The interrelationship of lameness, saddle slip and back shape in the general sports horse population. Saddle slip is usually blamed on saddle fit, crooked riders or horse shape, but may reflect hindlimb lameness. There are no studies of the frequency of occurrence of saddle slip and risk factors within a tested sample population of the general sports horse population. Objective: To quantify the frequency of saddle slip and to describe the association with lameness, thoracolumbar shape/symmetry, crooked riders and ill-fitting saddles. Methods: Nonrandom, cross-sectional survey using convenience sampling. Methods: Five hundred and six sports horses in normal work were assessed prospectively. Tho...
Risk factors associated with health disorders in sport and leisure horses in the Netherlands. Horses are used for a wide variety of purposes from being used for recreational purposes to competing at an international level. With these different uses, horses have to adapt to numerous challenges and changes in their environment, which can be a challenge itself in continuously safeguarding their welfare. The objective of this study was to assess the prevalence of health disorders with clinical examination and identify possible risk factors of health disorders affecting horse welfare in professional husbandry systems in the Netherlands. With the use of fixed protocols for recording health a...
Comparison of clinical examinations of back disorders and humans’ evaluation of back pain in riding school horses. Questionnaires are a common tool to assess people's opinion on a large scale or to sound them out about their subjective views. The caretakers' opinion about animals' "personality" has been used in many studies. The aim of the present study was to assess whether the owners' subjective evaluation was effective to detect back disorders. Back disorders have been shown to have a high prevalence in working horses. Caretakers from 17 riding schools (1 caretaker/school, 161 horses) were given a questionnaire about their horses' health status, including back disorders. Out of these 161 horses, 59 were...
Force and pressure distribution beneath a conventional dressage saddle and a treeless dressage saddle with panels. The objective of this study was to compare forces and pressure profiles beneath a conventional dressage saddle with a beechwood spring tree and a treeless dressage saddle without a rigid internal support and incorporating large panels and a gullet. The null hypothesis was that there is no difference in the force and pressure variables for the two saddles. Six horses were ridden by the same rider using the conventional dressage saddle and the treeless dressage saddle in random order and pressure data were recorded using an electronic pressure mat as the horses trotted in a straight line. The da...
