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.

McKeever KH.An increasing percentage of the equine population is more than 15 years old, many performing various athletic activities into their 20s. Studies of aged humans have led to a fine tuning of exercise prescription to promote fitness while preventing adverse and potentially dangerous effects of excessive exercise. However, limited data exist regarding the exercise capacity of aged horses. This article presents an overview of published studies on aging-induced decreases in physiologic function and exercise capacity in the horse. The information presented can be used as a guide for exercise prescrip...
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...
Mizobe F, Okada J, Shinzaki Y, Nomura M, Kato T, Yamada K, Spriet M.Desmitis of the oblique distal sesamoidean ligaments (ODSL) is caused by hyperextension of the metacarpophalangeal/metatarsophalangeal joint and has been described as a significant cause of lameness in racehorses. In this study, three Thoroughbred racehorses (age range: 3-6 years) were diagnosed with desmitis of the forelimb ODSL using standing low-field magnetic resonance imaging (sMRI).

Martin GS, Haynes PF, McClure JR.Between 1977 and 1984, 31 Thoroughbred horses (mean age, 2.8 years) were surgically treated for slab fractures of the third carpal bone. All fractures involved the articular surfaces of the intercarpal and the carpometacarpal joints in a frontal plane and had a cuboidal or slab shape. In 20 of the horses, the bone was fractured during racing and in 8 of the horses, the bone was fractured during race training. The right limb was affected more frequently than was the left limb (24 vs 7, P less than 0.05). Twenty-one (67.6%) horses raced at least once after recovery from the surgery. Data were av...
Osborn ML, Cornille JL, Blas-Machado U, Uhl EW.Navicular syndrome has been traditionally characterized by progressive lameness with chronic degeneration of the navicular bone. Advances in imaging techniques have revealed that its associated soft tissue structures are also affected. This distribution of lesions is explained by conceptualizing the equine navicular apparatus as an enthesis organ that facilitates the dissemination of mechanical stress throughout the tissues of the foot. The navicular apparatus has the same structural adaptations to mechanical stress as the human Achilles tendon complex. These adaptations efficiently dissipate ...

Takahashi T, Yoshihara E, Mukai K, Ohmura H, Hiraga A.Although the main cause of injury to the superficial digital flexor tendon (SDFT) is assumed to be high intensity loading of the tendon, to date the forces exerted on the SDFT during cantering have never been measured. Objective: To measure the force exerted on the SDFT at walk, trot and canter on a treadmill. Methods: Arthroscopically implantable force probes (AIFP) were implanted in the SDFT of the left and right forelimbs of 8 Thoroughbred horses (480-565 kg). The output of the AIFP was calibrated using the SDFT force calculated by inverse dynamics and an in vitro model of the lower forelim...
Nankervis KJ, Tranquille CA, Chojnacka K, Tacey JB, Deckers I, Newton JR, Murray RC.Water treadmill (WT) exercise may induce limb and back kinematics that meet specific training and rehabilitation goals. The study aimed to investigate the effects of walk speed, at different water depths (WDs), on limb and back kinematics of six Thoroughbreds exercising on a WT. Horses walked at 2.8/4.3/5.5/6.0 km/h (i.e. 0.8/1.2/1.5/1.7 m/s) at dry, metacarpophalangeal and carpal WD. Videography captured limb movement in the sagittal plane. Motion-capture measured thoracolumbosacral flexion-extension (FE), and lateral bend (LB) ranges of movement (ROM) using skin surface markers on the sixt...
Provan M, Ahmed Z, Stevens AR, Sardeli AV.Equine-assisted services (EAS) involves the use of horses within therapy, learning or horsemanship sessions and has been used with military veterans suffering from post-traumatic stress disorder (PTSD). This study systematically reviewed existing research on the use of EAS in the treatment of PTSD in military veterans and evaluated its effectiveness. A systematic review was performed, in May 2023, with searches and data extraction carried out from three separate databases (PubMed, JSTOR and Science Direct) related to testing the effect of EAS on PTSD outcomes in veterans. A risk of bias assess...
