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.
Keller J, Hassenstein MJ, Jung K, Geburek F.Ground reaction forces are accepted as gold standard for objective assessment of weightbearing lameness but measurements at the hoof are limited to experimental devices. This study aimed to evaluate whether innovative instrumented hoof boots (IHBs) could detect and monitor lameness in horses during diagnostic anaesthesia. Twenty-six horses referred for lameness examination (15 front limbs, 17 hindlimbs) were equipped with IHBs and body mounted inertial sensors. Data were collected simultaneously before and after diagnostic anaesthesia until objectively considered positive. Recorded IHB data i...

Lenarz J, Smit IH, Rhodin M, Lischer C, Fugazzola MC.Intramuscular vaccination is a routine component of equine medicine, but local muscle soreness may transiently affect gait symmetry. Objective data on vaccination-associated gait changes in horses are lacking. Objective: To investigate whether intramuscular vaccination induces measurable gait asymmetries depending on injection site, to inform recommendations on vaccination site selection and short-term exercise management. Methods: In this prospective, randomised, blinded, placebo-controlled study, eighteen clinically sound Warmblood horses were enrolled and received an intramuscular vaccinati...
Mazzucco L, Marcatili M, Withers J, Cantatore F.Superficial digital flexor tendinopathy is a common cause of forelimb lameness in Thoroughbred racehorses and sports horses; however, this condition is rarely observed in the hindlimb. A 16-year-old Irish sports horse gelding was presented with bilateral swelling in the plantar metatarsal region and severe bilateral hindlimb lameness visible at the walk. The lameness occurred after the cross-country phase of an eventing competition. The clinical suspicion of superficial digital flexor tendon (SDFT) injury was confirmed after ultrasonographic examination, which revealed an extensive core lesion...
Boger B, Naraian M, Hernandez E, Eaton A, Rockburn R, Tillman I, Payne S, Yob C, Panek C, Manfredi JM.Resistance bands used while horses are exercised with their handlers have shown benefits, but it is unknown if whole-body resistance bands used independently have therapeutic benefits. This study hypothesized that horses with varying gait asymmetries would experience improvements in lameness, muscular function, range of motion, posture, and cortisol following short-term use of a whole-body resistance band wrap (RBW). In this study, nine lame adult horses were evaluated with and without the RBW. The assessment included: objective gait analysis, acoustic myography, postural analysis, gait kinema...

Zhang Z, Yang Y, Ma Y, Mai Z, Fu H, Wang X, Cao X, Li T, Li J, Guo Q.With the growing popularity of equestrian sports, the incidence of athletic injuries in horses has also risen. Among these injuries, proximal sesamoid bone fracture (PSBF) and flexor tendinitis are particularly common in the forelimbs of sport horses and represent major causes of musculoskeletal impairment. A 5-year-old horse presented with obvious symptoms such as swelling at the left fetlock joint and metacarpal region after exercise. Through lameness assessment, diagnostic imaging, and hematological testing, the horse was diagnosed with PSBF complicated by flexor tendinitis. The affected ho...
Pécresse B, Moiroud C, Hanne-Poujade S, Hatrisse C, De Azevedo E, Coudry V, Jacquet S, Audigié F, Chateau H.Locomotor disorders involving the spine are a major cause of impaired performance and early retirement in sport horses. Swimming is increasingly incorporated into rehabilitation protocols, but its effects on spinal biomechanics remain poorly understood. This prospective study evaluated changes in thoracolumbar mobility in sixteen sport horses diagnosed with cervical or thoracolumbar axial musculoskeletal lesions over a 12-week rehabilitation program comprising 4 weeks of land-based training followed by 8 weeks during which swimming sessions were incorporated three times per week. Weekly measur...
Jastrzębska E, Dobbek D, Pawłowska A.Back pain in horses is a frequent musculoskeletal issue that affects performance and welfare. Magnetotherapy has been proposed as a complementary, non-invasive treatment to reduce pain and support soft tissue recovery, but studies in horses remain limited. This pilot study aimed to evaluate the effects of low-frequency pulsed magnetic field therapy on horses with hypersensitivity to palpation along the longissimus dorsi muscle. Four recreational horses participated in a 10-session magnetotherapy program, with changes assessed using palpation, neck flexibility tests, heart rate measurements and...
Sikorska U, Maśko M, Rey B, Domino M.Water treadmill (WT) exercise is used for horses' rehabilitation and training. Given that each training needs to be individualized for each horse, the goal is to assess whether infrared thermography (IRT) can serve as a non-invasive tool for daily monitoring of individual training and rehabilitation progress in horses undergoing WT exercise. Fifteen Polish Warmblood school horses were subjected to five WT sessions: dry treadmill, fetlock-depth water, fetlock-depth water with artificial river (AR), carpal-depth water, and carpal-depth water with AR. IRT images, collected pre- and post-exercise,...
Seery R, Graham-Wisener L, Wells DL.Equine-Assisted Services (EAS), which incorporate horses in a variety of ways in an effort to improve human wellbeing, have grown in popularity in recent years. Although much research has been conducted regarding the benefits that horses may provide for human health and wellbeing, little attention has been paid to practitioners' experiences and perspectives of the field, despite the fact they are uniquely positioned to advance our understanding of this area. This study aimed to explore practitioners' lived experiences of EAS, focusing on the benefits they observed, possible underlying mechanis...

Horses requiring a second surgery formed a fourth group (T). Ou...
Smith RKW, Schramme MC.Superficial digital flexor tendinopathy is one of the most common orthopedic soft tissue injuries in horses. The veterinary challenge for this condition is less related to identifying the presence of the injury (as it is usually readily evident clinically) but more related to improving the healing process so that the healed tendon is more like normal tendon in biology and function in order to reduce reinjury, which is the key adverse consequence of the injury. Diagnostic imaging has improved in recent years to aid with treatment choices and monitoring the healing process.
Ruspi BD, Bramlage LR, Ruggles AJ, Slone SA.To report the rate of survival, rate of return to racing, and quality of racing performance following surgical fixation of medial condylar fractures.

Objective: To determine the utility of ultrasonography to identify caudoproximal humeral stress fractures in racehorses. Methods: Clinical case series. Methods: Seven racehorses that had a clinical history consistent with the presence of a humeral stress fracture were examined using humeral ultrasono...
Ellis KL, Giancola S.Rehabilitation for tendon/ligament injury requires a multimodal approach to reduce pain, restore range of motion, improve proprioception/neuromotor control, and improve strength/endurance. Multiple tools are available to accomplish these goals. The rehabilitation program must be tailored to the individual patient regardless of injury type in order to return the horse to full athletic activity and reduce the risk of reinjury.
Horne CR, Redding WR.The location of a suspensory ligament (SL) injury heavily influences the clinical presentation, prognosis, and treatment options. Diagnostic imaging is necessary to provide an accurate diagnosis and is critical to ensure the institution of the most appropriate treatment. The hindlimb proximal SL in particular can be challenging to diagnosis, carries a guarded prognosis, and typically requires aggressive treatment to achieve soundness.
Pluim M, Reynolds A, McClure S.High-power laser therapy and extracorporeal shock wave therapy (ESWT) can be safely used to treat tendon and ligament injuries in horses, and the potential beneficial effects have been described. The power of low level lasers is not sufficient for treatment of tendon and ligament injuries in horses. ESWT is used more often to treat tendon and ligament injuries than it is for any other type of condition in horses, but there is limited supporting scientific evidence. Further research should focus on establishing dosage and treatment protocols for both laser therapy and ESWT in horses with clinic...
Connard SS, Schnabel LV.This review explores the use of biologics in the treatment of tendon and ligament injuries in horses, focusing on current and emerging therapies aimed at enhancing tissue repair and regeneration. It discusses the role of scaffold-based therapies, growth factors, blood-derived and tissue-derived biologics, and gene therapy as biologic regenerative therapies for improving healing outcomes. The review evaluates the mechanisms, efficacy, and challenges of biologics in clinical applications, highlighting recent advances and clinical studies. It provides an overview of current trends and future dire...
Tay A, McMaster M.Equine tendon lacerations are not uncommon secondary to traumatic wounds and degloving lacerations. These wounds are often contaminated and, therefore, basic principles of wound assessment and management are critical to identify the extent of an injury. Ancillary tools to aid physical examination include radiography, ultrasonography, and synoviocentesis (eg, if involving a joint and/or tendon sheath). Prolonged convalescence period, continued external coaptation, and controlled exercise are mainstays of treatment following tenorrhaphy. A poor prognosis for return to full athletic function is e...
Boado A, Pollard D, Dyson S.There is limited information about the orthopaedic health of dressage horses. This study aimed to document the orthopaedic status, lesion distribution, and evolution of injuries in 70 horses undergoing a minimum of five in-depth orthopaedic assessments at six-months' intervals. Warmblood (70.0%) and Iberian (24.3%) breeds predominated. The median lameness grade at initial examination was 2/5 (interquartile range 2,2; range 0,3). Hypermetria (42.9%) or hypermetria and weakness (12.9%) were observed at the initial examination and did not change over time. Metacarpophalangeal/metatarsophalangeal ...
Quam V.Inflammation plays a role in acute and chronic equine tendon/ligament injury; anti-inflammatories are often indicated. Local corticosteroids provide consistent and profound short-term effects on pain and inflammation across species. However, there is no demonstrated benefit in the long term, and complications can occur. Alternative biologic anti-inflammatory treatments are available and should be used in horses at risk of complications. Nonetheless, corticosteroids remain an affordable and effective anti-inflammatory that, with continued research, may be indicated on a case-by-case basis as pa...
Resano-Zuazu M, Carmona JU, Argüelles D.Myofascial pain syndrome (MPS) is a common source of musculoskeletal pain, characterized by trigger points (TrPs). In horses, MPS is frequently underdiagnosed, and evidence on DN effectiveness is limited. This study investigated whether DN can improve the biomechanics in horses using an artificial intelligence (AI)-based markerless smartphone application (app). Fourteen horses participated, including nine used in assisted therapy, four leisure horses, and one with mixed use. The presence of TrPs was evaluated in six muscles through manual palpation: brachiocephalicus, trapezius, gluteus medius...
Calle-González N, Rivero JL, Olivares J, Miró F, Argüelles D, Requena F, Munoz A.Capacitive-resistive electrical transfer (CRET) is an endogenous non-invasive technique, used as deep diathermy.

Dyson SJ.There is a lack of long-term follow-up data for outcome of medical treatment of superficial digital flexor (SDF) tendonitis. Objective: To determine whether intralesional injection of hyaluronan, beta aminoproprionitrile fumarate (BAPN) or polysulphated glycosaminoglycans (PSGAG) or systemic administration of PSGAG yielded better results than a controlled exercise programme alone in the management of SDF tendonitis, with a minimum follow-up period of 2 years after resumption of full work; and to determine whether reinjury rate was related to sports discipline and whether fibre alignment score ...
Dowling BA, Dart AJ, Hodgson DR, Smith RK.The superficial digital flexor tendon (SDFT) is an elastic structure that during maximal exercise appears to operate close to its functional limits. The biomechanical and biochemical responses to exercise, injury, and healing are still poorly understood but ongoing research is providing valuable new information which is addressed in this review. It appears that the SDFT matures early, after which time it has limited ability to adapt to stress and undergoes progressive degeneration. Focal hypocellularity, collagen fibril degeneration, selective fibril loading and alterations in the noncollageno...
Smith RK.Optimal management of tendon overuse injuries in equine and human athletes should avoid the formation of excessive scar tissue, regenerate normal tendon matrix, and reduce re-injury rates. We hypothesized that the implantation of marrow-derived stromal stem cells (BM-MSCs), in far greater numbers than are present normally within tendon tissue, would synthesize a matrix more closely resembling tendon matrix than scar tissue, and hence increase the capacity to return to performance successfully. This article reviews the technique used clinically in the horse and the current outcome data for hors...
Carvalho Ade M, Badial PR, Álvarez LE, Yamada AL, Borges AS, Deffune E, Hussni CA, Garcia Alves AL.Tendon injury is a major cause of lameness and decreased performance in athletic equines. Various therapies for tendonitis have been described; however, none of these therapies results in complete tissue regeneration, and the injury recurrence rate is high even after long recovery periods involving rest and physiotherapy. Methods: A lesion was induced with collagenase gel in the superficial digital flexor tendon in the center portion of the metacarpal region of eight equines of mixed breed. After two weeks, the lesions of the animals in the treated and control groups were treated through the i...
Hidaka C, Goodrich LR, Chen CT, Warren RF, Crystal RG, Nixon AJ.Cartilage has a limited capacity to heal. Although chondrocyte transplantation is a useful therapeutic strategy, the repair process can be lengthy. Previously we have shown that over expression of bone morphogenetic protein-7 (BMP-7) in chondrocytes by adenovirus-mediated gene transfer leads to increased matrix synthesis and cartilage-like tissue formation in vitro. In this context we hypothesized that implantation of genetically modified chondrocytes expressing BMP-7 would accelerate the formation of hyaline-like repair tissue in an equine model of cartilage defect repair. Methods: Chondrocyt...
Lange-Consiglio A, Corradetti B, Bizzaro D, Magatti M, Ressel L, Tassan S, Parolini O, Cremonesi F.The aim of this work was to isolate, for the first time, progenitor-like cells from the epithelial (AECs) and mesenchymal (AMCs) portions of the horse amniotic membrane, and to define the biological properties of these cells. AECs displayed polygonal epithelial morphology, while AMCs were fibroblast-like. Usually, six to eight passages were reached before proliferation decreased, with 13.08 and 26.5 cell population doublings attained after 31 days for AECs and AMCs, respectively. Immunocytochemical studies performed at passage 3 (P3) showed that both cell populations were positive for the expr...

Carraro U, Kern H, Gava P, Hofer C, Loefler S, Gargiulo P, Mosole S, Zampieri S, Gobbo V, Ravara B, Piccione F, Marcante A, Baba A, Schils S, Pond A....There is something in our genome that dictates life expectancy and there is nothing that can be done to avoid this; indeed, there is not yet any record of a person who has cheated death. Our physical prowess can vacillate substantially in our lifetime according to our activity levels and nutritional status and we may fight aging, but we will inevitably lose. We have presented strong evidence that the atrophy which accompanies aging is to some extent caused by loss of innervation. We compared muscle biopsies of sedentary seniors to those of life long active seniors, and show that these groups i...
Ricco S, Renzi S, Del Bue M, Conti V, Merli E, Ramoni R, Lucarelli E, Gnudi G, Ferrari M, Grolli S.Overstrain tendonitis are common pathologies in the sport horses. Therapeutic approaches to tendon healing do not always result in a satisfactory anatomical and functional repair, and healed tendon is often characterized by functional impairment and high risk of reinjury. Recently, mesenchymal stem cells (MSCs) and platelet rich plasma (PRP) have been proposed as novel therapeutic treatments to improve the tendon repair process. MSCs are multipotent, easy to culture and being originated from adult donors do not pose ethical issues. To date, autologous MSCs have been investigated mainly in the ...
Tseng SH, Chen HC, Tam KW.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 ...
Weishaupt MA, Wiestner T, Hogg HP, Jordan P, Auer JA.The study was performed to obtain a detailed insight into the load and time shifting mechanisms of horses with unilateral weight-bearing forelimb lameness. Reversible lameness was induced in 11 clinically sound horses by applying a solar pressure model. Three degrees of lameness (subtle, mild and moderate) were induced and compared with sound control measurements. Vertical ground reaction force-time histories of all four limbs were recorded simultaneously on an instrumented treadmill. Four compensatory mechanisms could be identified that served to reduce structural stress, i.e. peak vertical f...

In cBMSC- and BMMNCS-treated tendons, a high expression of cartilage oligomeric matrix protein...
Sterba JA, Rogers BT, France AP, Vokes DA.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...
Goodship AE, Birch HL, Wilson AM.Injury of the collagenous structures comprising tendons and ligaments, either from acute trauma or from repetitive strain lesions, results in protracted periods of disability. The resolution of such injuries often fails to restore the normal morphologic and functional characteristics of the structure and, therefore, either compromises the future performance of the individual or predisposes to an increased risk of recurrent injury.
O'Meara B, Bladon B, Parkin TD, Fraser B, Lischer CJ.There is limited information regarding the number of races and the period for evaluation of outcome which is critical for assessment of SDF tendonitis treatments. Objective: To evaluate the re-injury rate and racing performance of Thoroughbred racehorses that sustain SDF tendonitis in relation to matched controls in terms of number of races post treatment and maximum racing performance ratings before and after injury. Methods: Clinical records and racing histories of 401 racehorses with a first occurrence of SDF tendonitis diagnosed by ultrasonography. Controls were of the same age, sex and we...
Snider L, Korner-Bitensky N, Kammann C, Warner S, Saleh M.A systematic review of the literature on horseback riding therapy as an intervention for children with cerebral palsy (CP) was carried out. The terms horse, riding, hippotherapy, horseback riding therapy, equine movement therapy, and cerebral palsy were searched in electronic databases and hand searched. Retrieved articles were rated for methodological quality using PEDro scoring to assess the internal validity of randomized trials and the Newcastle Ottawa Quality Assessment Scale to assess cohort studies. PICO questioning (Population, Intervention, Comparison, and Outcomes) was used to identi...
Clegg PD, Strassburg S, Smith RK.Injuries to tendons are common in both human athletes as well as in animals, such as the horse, which are used for competitive purposes. Furthermore, such injuries are also increasing in prevalence in the ageing, sedentary population. Tendon diseases often respond poorly to treatment and require lengthy periods of rehabilitation. The tendon has a unique extracellular matrix, which has developed to withstand the mechanical demands of such tensile-load bearing structures. Following injury, any repair process is inadequate and results in tissue that is distinct from original tendon tissue. There ...
Geburek F, Gaus M, van Schie HT, Rohn K, Stadler PM.Regenerative and anti-inflammatory effects on tendinopathies have been attributed to blood-derived biologicals. To date the evidence for the efficacy of autologous platelet-rich plasma (PRP) treatment of naturally occurring equine tendinopathies is limited. The purpose of this placebo-controlled clinical trial was to describe the effect of a single treatment of equine superficial digital flexor tendon (SDFT) disease with PRP on clinical and ultrasonographic parameters. Twenty horses with naturally occurring tendinopathies of forelimb SDFTs were randomly assigned to the PRP-treated group (n =...
Broeckx S, Suls M, Beerts C, Vandenberghe A, Seys B, Wuertz-Kozak K, Duchateau L, Spaas JH.Cell-based therapies, such as treatments with mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) are thought to have beneficial effects on the clinical outcome of orthopedic injuries, but very few animal studies with large sample size are published so far. Therefore, the aim of this study was to assess the safety and report the clinical outcome of allogenic, immature or chondrogenic induced MSCs in combination with PRP for the treatment of degenerative joint disease (DJD) in 165 horses. MSCs and PRP were isolated from a 6-year-old donor horse and transplanted either in their native s...

Fortier LA, Smith RK.After tendon injury, the scar tissue that replaces the damaged tendon results in a substantial risk for reinjury. The goal of regenerative therapies is to restore normal structural architecture and biomechanical function to an injured tissue. Successful restoration processes for any tissue are thought to recapitulate those of development, in which there are spatial and temporal interactions between scaffold, growth factors, and cell populations.
Shojaee A, Parham A.Tendon injuries, as one of the most common orthopedic disorders, are the major cause of early retirement or wastage among sport horses which mainly affect the superficial digital flexor tendon (SDFT). Tendon repair is a slow process, and tendon tissue is often replaced by scar tissue. The current treatment options are often followed by an incomplete recovery that increases the susceptibility to re-injury. Recently, cell therapy has been used in veterinary medicine to treat tendon injuries, although the risk of ectopic bone formation after cell injection is possible in some cases. In vitro teno...
