Rehabilitation for horses refers to the process of restoring physical function and performance following injury, illness, or surgery. This process often involves a combination of veterinary care, physical therapy, and specialized training techniques. Rehabilitation aims to promote healing, improve mobility, and prevent further injury. Common methods used in equine rehabilitation include controlled exercise programs, hydrotherapy, and the use of therapeutic modalities such as laser therapy and ultrasound. The effectiveness of these methods is evaluated through clinical assessments and performance metrics. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, outcomes, and advancements in the field of equine rehabilitation.

King MR.Physiotherapeutic exercises aimed at stimulating motor control, flexibility, and stability are regularly employed in human physical therapy programs. Specifically, the use of such exercises has been shown to reduce both pain and reinjury. Pursuant to the equine patient, several core strengthening exercises and their role in activating deep epaxial musculature to subsequently improve postural motor control and alter thoracolumbar kinematics have been investigated. Both baited and passive exercises offer opportunities to facilitate stretching during dynamic phases and strengthening during static...
Haussler KK, Holt TN.There is a growing body of evidence to support the use of spinal mobilization and manipulation techniques in equine practice. Outcome parameters reported across studies include measures of joint motion, nociception, muscle tone, and performance. Spinal examination procedures include static and dynamic assessments of the quantity and the quality of both active and passive movements. Tiered treatment approaches are recommended to stage the application of various therapies based on ease, cost, and efficacy.
Luomala T.Fascia is a complex and intriguing tissue, which can take on structural properties of being loose or dense, irregular or regular. Fascia functions by connecting, separating, and uniting different structures of the body. Myofascial dysfunction can be a significant source of pain and can be categorized as densification, adhesion, and fibrosis. Digital palpation and treatment of myofascial disorders can be provided via superficial or deep techniques. Different myofascial treatment techniques include slow and fast techniques, which can be applied at different depths, angles, and rhythms.

Schils S, Ober T.When diagnosing neuromuscular injury and pain, the use of biomechanical evaluations to assess the mechanics of movement patterns has been useful in the human population. Functional electrical stimulation (FES) is a technology that can create action potentials to produce musculoskeletal movement that is almost indistinguishable from the voluntary kinematics produced by the nervous system. To create controlled and precise musculoskeletal movements in humans and in horses, FES has been shown to be effective. In humans, the kinematic information obtained from FES data has been utilized to direct f...
Ward J, Hovey A, Brownlee K.Across mental health professionals, there is growing interest in the field of Equine-Assisted Therapy (EAT). Preliminary evidence suggests EAT is beneficial for a wide spectrum of client populations. EAT programs may be based on groundwork alone, where participants interact with the horses from the ground only, or they may incorporate mounted activities. It remains unclear whether mounted activities add therapeutic benefits to the EAT experience for participants. This scoping review explored whether mounted activities, specifically where the client rides the horse, contribute to distinct thera...
Johnson SA.Rehabilitation of the neurologic horse represents a unique challenge for the equine practitioner. Improving postural stability and balance control through improving the strength of the spinal stabilizer muscle multifidus remains one of the most promising rehabilitative targets. This muscle can be targeted through the use of physiotherapeutic exercises, various forms of perturbation, and even whole-body vibration. Neuroanatomic localization and diagnosis specificity enable the practitioner to determine suitability for such rehabilitative tasks, and with the advent of evolving strategies and com...
Berner D, Brehm W, Gerlach K, Gittel C, Offhaus J, Paebst F, Scharner D, Burk J.Treatment of tendon disease with multipotent mesenchymal stromal cells (MSC) is a promising option to improve tissue regeneration. To elucidate the mechanisms by which MSC support regeneration, longitudinal tracking of MSC labelled with superparamagnetic iron oxide (SPIO) by magnetic resonance imaging (MRI) could provide important insight. Nine equine patients suffering from tendon disease were treated with SPIO-labelled or nonlabelled allogeneic umbilical cord-derived MSC by local injection. Labelling of MSC was confirmed by microscopy and MRI. All animals were subjected to clinical, ultrason...
Papachristos A, Edwards E, Dowrick A, Gosling C.Despite a number of injury prevention campaigns and interventions, horse riding continues to be a dangerous activity, resulting in more accidents per hour than motorcycling, skiing and football.

Greve L, Pfau T, Dyson S.Altered body lean has been subjectively observed during lungeing in lame horses. The objectives were to quantify the influence of lameness on body lean in trot on the lunge and to investigate the influence of improvement in lameness on the differences in body lean between reins. Thirteen lame horses were trotted in straight lines and lunged on a 10m-diameter circle on both reins before and after lameness was subjectively substantially improved by diagnostic analgesia. A global position system-aided inertial measurement unit attached to the tubera sacrale quantified body lean. Differences betwe...
Harman J.Examining the fit of the saddle is perhaps the most important aspect of examining a horse with a suspected back problem. If the back problem is corrected and a poorly fitting saddle is placed on the back, the problems will return. An ill-fitting saddle contributes to direct and compensatory lower leg lameness making it even more imperative to correct the fit. A correctly fitting saddle enhances both the horse and rider's ability to perform with accuracy, lightness, and freedom of movement.
Audigié F, Pourcelot P, Degueurce C, Geiger D, Denoix JM.The aim of this paper is to present a method allowing the identification of the lame limb in trotting horses. Using a 3-D kinematic analysis system, 13 sound and 25 lame horses fitted with 4 skin markers placed on the dorsal midline of their trunk were recorded while trotting on a track in the conditions of the routine lameness examination. The vertical displacements of the trunk markers underwent Fourier analysis. Results indicated that these displacements could be represented using only the first and second harmonics. From these two harmonics, indices were then developed. The sensitivity of ...
Pugh TJ, Bolin D.Some 30 million Americans are involved in equestrian sports. Although there is significant literature regarding catastrophic injury, there is very little literature that addresses overuse injury and its effect on rider and horse. As the horse and rider function as a unit, overuse injuries to the rider can affect the horse's training and responsiveness. Sports physicians treating riders should understand correct posture in the saddle and its alteration by muscular imbalance and injury. This review discusses common equestrian events, and common overuse injuries in recreational and competitive ri...

Objective: To report the long-term (≥12 months) outcome of horses with foot lesions following medical therapy. Objective: 1) There is no association between clinical parameters considered and a poor response to therapy. 2) Horses with a deep digital flexor tendinopathy are less likely to respond to medical therapy than horses without a deep digital flexor tendino...
Bottagisio M, Pellegata AF, Boschetti F, Ferroni M, Moretti M, Lovati AB.Tendon ruptures and/or large losses remain to be a great clinical challenge and often require full replacement of the damaged tissue. The use of auto- and allografts or engineered scaffolds is an established approach to restore severe tendon injuries. However, these grafts are commonly related to scarce biocompatibility, site morbidity, chronic inflammation and poor biomechanical properties. Recently, the decellularisation techniques of allo- or xenografts using specific detergents have been studied and have been found to generate biocompatible substitutes that resemble the native tissue. This...
Clayton HM.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...
The objective of this study was to graft autologous mesenchymal stem cells (MSCs) at the site of surgical repair of a soft palate defect in an adult horse in an attempt to improve wound healing and to investigate whether the transplanted MSCs would integrate into the soft palate structure and participate in regeneration. Bone marrow was collected from an adult horse with a full-thickness soft palate defect. The MSCs were isolated, cultured in monolayers, and labeled with 5-bromo-2-desoxymidine (BrdU) and chloromethylbenzamido-DiI-derived (cm-DiI) before transplantation. The soft palate defect ...

As yet, no longitudinal studies have used strain ratio to evaluate the progression of stiffness in SDFT injuries. Objective: To test the hypothesis that strain ratio can evaluate the recovery of stiffness during the healing of SDFT inj...
Lischer CJ, Ringer SK, Schnewlin M, Imboden I, Fürst A, Stöckli M, Auer J.The objective of the present clinical report was to investigate the short- and long-term outcomes of chronic proximal suspensory desmitis (PSD) treated with Extracorporeal Shockwave Treatment (ESWT). Fifty-two horses with chronic PSD in the forelimb (34 cases) or hindlimb (22 cases) were included in the study. Three horses had lesions in both hindlimbs and one in both forelimbs. The origin of the suspensory ligament was treated every three weeks for a total of three treatments using 2000 impulses applied by a focused ESWT device (Equitron) at an energy flux density of 0.15 mJ/ mm2. This treatm...
Dart AJ, Cries L, Jeffcott LB, Hodgson DR, Rose RJ.To evaluate the effect of a commercially available 25% propylene glycol hydrogel preparation (Solugel; Johnson and Johnson Medical, North Ryde, Australia) on healing of full-thickness skin wounds on the distal aspect of the limb in horses. Methods: Experimental. Methods: Eight Standardbred horses. Methods: Standardized (2.5 x 2.5 cm) full-thickness skin wounds were created over the mid-dorsomedial aspect of both metacarpi in 8 horses. One wound in each horse was dressed with saline solution (0.9% NaCl) soaked gauze, and one was treated with Solugel under dry regular gauze; wounds were then ban...
Dirienzo LN, Dirienzo LT, Baceski DA.The study was designed to document the heart rate response to therapeutic riding in children with cerebral palsy having mild-to-severe disability. Methods: Participants consisted of eight youth riders with cerebral palsy, divided into two groups: ambulatory and wheelchair dependent. The riders received continuous digital heart rate monitoring during 10 weekly 20-minute therapeutic horseback riding sessions. Results: The averaged resting, median, and peak heart rate values, as well as the peak percentage heart rate reserve values, were significantly higher in the wheelchair-dependent group. Con...
