Veterinary practice in relation to horses encompasses the medical care, management, and treatment of equine species. This field involves various aspects of equine health, including preventive care, diagnosis, and treatment of diseases, surgical interventions, and emergency care. Equine veterinarians employ a range of diagnostic tools and techniques such as physical examinations, imaging, and laboratory tests to assess and monitor horse health. In addition to addressing physical ailments, veterinary practice also includes nutritional management, reproductive health, and performance-related issues. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, advancements, and outcomes in veterinary practices specific to equine health.
Bouhali O, Bensmail H, Sheharyar A, David F, Johnson JP.Great advances have been made in human health care in the application of radiomics and artificial intelligence (AI) in a variety of areas, ranging from hospital management and virtual assistants to remote patient monitoring and medical diagnostics and imaging. To improve accuracy and reproducibility, there has been a recent move to integrate radiomics and AI as tools to assist clinical decision making and to incorporate it into routine clinical workflows and diagnosis. Although lagging behind human medicine, the use of radiomics and AI in veterinary diagnostic imaging is becoming more frequent...
Haughan J, Ortved KF, Robinson MA.Gene therapy uses genetic modification of cells to produce a therapeutic effect. Defective or missing genes can be repaired or replaced, or gene expression can be modified using a variety of technologies. Repair of defective genes can be achieved using specialized gene editing tools. Gene addition promotes gene expression by introducing synthetic copies of genes of interest (transgenes) into cells where they are transcribed and translated into therapeutic proteins. Protein production can also be modified using therapies that regulate gene expression. Gene therapy is currently prohibited in bot...
Jacobsen S.Serum amyloid A (SAA) has become an indispensable part of the management of equine patients in general practice and specialized hospital settings. Although several proteins possess acute phase properties in horses, the usefulness of SAA exceeds that of other acute phase proteins. This is due to the highly desirable kinetics of the equine SAA response. SAA concentrations exhibit a rapid and pronounced increase in response to inflammation and a rapid decline after the resolution of inflammation. This facilitates the detection of inflammatory disease and real-time monitoring of inflammatory activ...
Schusser GF, Köller G, Recknagel S, Lindner A.The hay producing plants, concentrate, straw and meadows could be contaminated by the aerosols of glyphosate based herbicide during spraying process of crops and pre-harvest desiccation treatment of cereals. The aim of this study is to investigate the concentration of glyphosate in the duodenal fluid of horses with gastric ulcer syndrome. The stomach and duodenum of referred untreated horse patients (n=92) with colic, weight loss, diarrhoea, anemia or performance intolerance were endoscopically examined right after the admission. Duodenal fluid (40 ml) was collected from the duodenal region ...
Hollis AR.Sarcoids are the most common cutaneous neoplasm of the horse, arising as a result of a neoplastic proliferation of fibroblasts associated with infection with bovine papillomavirus, most notably types 1 and 2. Although they do not metastasise, they are locally invasive and aggressive, and can lead to important welfare concerns, interfere with tack and therefore impede athleticism, and undoubtedly lead to a reduction in the value of affected horses. This review discusses the evidence behind the most commonly used treatments for equine sarcoids. The most commonly used treatments are discussed. No...
Vidović A, Jansen D.The first part of this case report describes the surgical treatment of a unilateral mandibular fracture in the standing horse by using a fixateur type I. By the time of implant removal, the fracture had completely healed. However, during implant removal, an implant failure of 2 of the 4 implants occurred with fragments remaining in the bone. The second part of the report focuses on the development of a special surgical instrument that was designed for removal of the implant fragments. Furthermore, the surgical method allowing the entire extirpation of the fragments within a second surgery is d...
Johnson SA, Richards RB, Frisbie DD, Esselman AM, McClure SR.Over the past three decades, electrohydraulic extracorporeal shock wave therapy (ESWT) as a treatment modality for equine orthopaedic disorders has sparked exponential interest among practitioners, but its clinical applications are quickly evolving and a current review highlighting modernised equine clinical use is lacking. The objective of this review is to summarise the most current ESWT technology, evidence for its use, proposed mechanisms of action and clinical applications in horses while also highlighting the areas requiring further investigation. The three ways to generate a shock wave ...
Douglas H, Midon M, Shroff K, Floriano D, Driessen B, Hopster K.The placement of caudal epidural catheters in horses has become more frequent as a multi-modal analgesic strategy. Despite its integration into clinical practice, there are limited reports describing the use of caudal epidural catheterization for prolonged use in horses. The purpose of this study was to characterize the hospitalized caseload undergoing epidural catheterization for long-term epidural analgesic administration, to report the response to epidural therapy and observed complications, and to describe patient outcomes. Medical records of hospitalized equine patients that underwent pla...
Flood J, Stewart AJ.Effective pain management in horses can be a challenge despite the understanding that appropriate analgesia improves animal welfare and increases treatment success. The administration of NSAID drugs, particularly phenylbutazone and flunixin, are common practice in equine veterinary patients. Known for their analgesic and anti-inflammatory properties, NSAIDs are used for the treatment of a variety of conditions in horses, from gastrointestinal to orthopedic pain. Despite extensive usage, NSAIDs have a narrow margin of safety and the body of literature documenting the efficacy and side effects o...
Murillo C, Weng HY, Weil AB, Kreuzer M, Ko JC.This study aimed to investigate the use of electroencephalography (EEG) for detecting brain activity changes perioperatively in anesthetized horses subjected to surgery. Twelve adult horses undergoing various surgeries were evaluated after premedication with xylazine and butorphanol, induction with ketamine, midazolam, and guaifenesin, and maintenance with isoflurane. The frontal EEG electrodes were placed after the horse was intubated and mechanically ventilated. The EEG data were collected continuously from Stage (S)1-transition from induction to isoflurane maintenance, S2-during surgery, S3...

Methods: A scoping review was conducted in CAB, Web of Science, Scopus and PubMed databases using a PCC (Population-equids, Concept-complications, adverse events, sequelae, failure to cure, technical failure, disease progression and Context-postoperative period af...
Kuroda T, Minamijima Y, Mita H, Tamura N, Fukuda K, Kuwano A, Toutain PL, Sato F.A pharmacokinetics/pharmacodynamics (PK/PD) approach was used to determine the best empirical dosage regimen of cefazolin (CEZ) after intramuscular (IM) administration of CEZ in horses. Seven horses received a single IM or intravenous (IV) administration of CEZ of 5 mg/kg bodyweight (BW) according to a crossover design. CEZ plasma concentrations were measured using LC-MS/MS. The plasma concentrations in these seven horses and those of six other horses obtained in a previous study with an IV CEZ dose of 10 mg/kg were modelled simultaneously using NonLinear Mixed-Effect modelling followed by M...
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...
Repac J, Mangan E, Xie H.Acupuncture is an inexpensive nonpharmacological modality that has a variety of musculoskeletal, neurologic, and internal medicine applications for the equine practitioner. Common uses include back pain colic, laminitis, laryngeal hemiplegia, and suprascapular neuropathy. Although there is a growing body of literature supporting the use of acupuncture in equids, there remains a need for further robust, double-blinded, placebo-controlled clinical efficacy trials.
Story MR.Equine cervical pain and dysfunction may be difficult to diagnose and effectively manage. Understanding techniques in integrative medicine often allows the practitioner to observe and palpate areas of pain and dysfunction in the horse being evaluated in ways often not taught or used in conventional medicine. There are many integrative therapies that also may be utilized to more effectively manage these horses, resulting in a more comfortable and functional horse.
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.
Clayton HM, MacKechnie-Guire R.Not too long ago, tack often fell into the "one size fits all" category but, fortunately, times have changed. In recent years, tack has become not only more functional but also a fashion statement. This article describes scientific concepts of the saddle, bridle, and bit with emphasis on clinical signs associated with ill-fit or incorrect use.
Haussler KK.Integrative medicine is based on a model of being proactive and promoting health and wellness, rather than being reactive and solely focusing on episodic disease processes. Integrative medicine incorporates a holistic approach to clinical practice that encourages owner involvement with a focus on individualized care, maintained wellness, optimized performance, and disease prevention. Health promotion and preventative care require a different set of clinical skills and perspectives than is typically provided by a traditional veterinary education. Productive interprofessional collaborations are ...
Henneman K.Addressing poor performance issues in horses is a common yet challenging request to veterinarians. Often, there are limited field diagnostic or therapy choices. Growing lay popularity in integrative therapies, as well as increasing clinical incorporation, is creating more awareness of their clinical applications. Many modalities are showing increasing evidence of positive outcomes with minimal harm, but additional safety and efficacy evaluation is needed. Integrative modalities have unique ways of perceiving disease patterns that are different from more modern approaches, and these different p...
Adair S.This article serves as an introduction into integrative case management as it applies to the horse's mental health, pain management, and tissue healing. The integrative philosophy pertains to the combination of conventional Western medicine and complementary and alternative therapies to provide the best patient care possible using currently available evidence. The goal is to improve the health of the patient in a more holistic manner.
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.
Goff L.This article provides the equine practitioner with a review of sacroiliac joint pain and dysfunction and outlines the importance of providing a specific prescription for a safe and effective therapeutic exercise program. The continuum of clinical dysfunction associated with the sacroiliac region is presented with prescribed interventions. The intent is to encourage the practitioner to perform a thorough assessment of the sacroiliac joint and the adjacent soft tissues and to use sound clinical reasoning to formulate a therapeutic exercise plan.

Kirkwood NC, Hughes KJ, Stewart AJ.Substantial morbidity results from pituitary pars intermedia dysfunction (PPID) which is often underestimated by owners and veterinarians. Clinical signs, pathophysiology, diagnostic tests, and treatment protocols of this condition are reviewed. The importance of improved recognition of early clinical signs and diagnosis are highlighted, as initiation of treatment will result in improved quality of life. Future research should be targeted at improving the accuracy of the diagnosis of PPID, as basal adrenocorticotropic hormone (ACTH) concentration can lack sensitivity and thyrotropin releasing ...
Galen GV, Olsen E, Siwinska N.Creatinine only allows detection of kidney disease when 60 to 75% of the glomerular function is lost and is therefore not an ideal marker of disease. Additional biomarkers could be beneficial to assess kidney function and disease. The objectives are to describe new equine kidney biomarkers. This systematic review assesses the available literature, including the validation process and reference values, following which the authors suggest recommendations for clinical use. SDMA may have some potential as equine kidney biomarker, but there is currently a lack of evidence that SDMA offers any advan...

Following a crossover protocol, horses were administered flunixin meglumine (1.1 mg/kg, IV, q 12 h for 5 days), allowed a 6-month washout period, and then administered firocoxib (0.3 mg/kg, PO, once, then 0.1 mg/kg, PO, q 24 h for 4 days). Omeprazole (1 mg/kg, PO, q 24 h) was administered concurrently with each NSAID. Viscoelastic coagulation profiles and traditional coagula...
Dickey JP, Carmalt JL, Reiswig JD.The determination of a horse's age by its dentition is a technique that has been employed by horse owners and professionals since at least 600 BC. While aging teeth based on incisor wear patterns is common, wear patterns in the cheek teeth may also be useful. As horses continue to live longer, we routinely examine horses into their 20's and 30's, and it is becoming more common to observe aging changes in the cheek teeth. To our knowledge, this study is the first to use easily obtained clinical observation of the expiration of cheek teeth infundibula to age horses of advanced ages (16 to 35 yea...

Fennig MW, Weber E, Santos B, Fitzsimmons-Craft EE, Wilfley DE.Eating disorders (EDs) are deadly illnesses with high relapse rates, highlighting need for better interventions. Animal-assisted therapy (AAT) has been implemented supplementally for EDs, with horses utilized at many residential facilities. AAT shows promise with meta-analyses of randomized control trials (RCTs) showing significant decreases in depression, anxiety, and negative affect; however, no review to date has evaluated efficacy for EDs. Therefore, this study conducted a systematic review of primary literature to investigate the efficacy of AAT for EDs. A systematic review was conducted ...
Helal IE, Al-Abbadi HA, El-Daharawy MH, Ahmed MF.Delayed healing associated with distal limb wounds is highly challenging in equine clinical practice. This study aimed to evaluate healing rates between chronic non-granulating wounds of horse distal limbs that were treated with maltodextrin/ascorbic acid gel alone or in combination with povidone-iodine 1% solution and those treated with povidone-iodine 1% only throughout the study period (35 days) in clinical settings. The study was conducted on 18 adult horses (3-15 years old). Based on the treatment regimen utilized, the horses were divided into three groups (n = 6), with each group having ...
Sullivan KA, Hill AE, Haussler KK.Common methods used to treat back problems in horses need to be assessed objectively. Objective: To measure spinal mechanical nociceptive thresholds (MNTs) and evaluate the effects of chiropractic, massage and phenylbutazone, compared with active and inactive control groups. Methods: Baseline MNTs at 7 sites within the thoracolumbar and sacral regions were measured in 38 healthy mature horses exhibiting no clinical signs of lumbar pain. Horses were assigned to one of 3 treatment groups: instrument-assisted chiropractic treatment, therapeutic massage and phenylbutazone; or 2 control groups: rid...
Furr MO, Lessard P, White NA.Thirty-two physical examination and laboratory variables were recorded during examination of 165 horses admitted for acute abdominal disease. Univariate analyses were performed to determine which of the variables were significantly different between horses that lived or died. Stepwise logistic regression was performed to identify variables with the best predictive value. Four variables (heart rate, peritoneal fluid total protein concentration, blood lactate concentration, and abnormal mucous membrane) remained significant when entered into the model. Histograms for each significant variable we...
Starke SD, Oosterlinck M.Visual equine lameness assessment is often unreliable, yet the full understanding of this issue is missing. Here, we investigate visual lameness assessment using near-realistic, three-dimensional horse animations presenting with 0-60 per cent movement asymmetry. Animations were scored at an equine veterinary seminar by attendees with various expertise levels. Results showed that years of experience and exposure to a low, medium or high case load had no significant effect on correct assessment of lame (P>0.149) or sound horses (P≥0.412), with the exception of a significant effect of case l...
Lees P, Higgins AJ.Weak organic acids possessing anti-inflammatory, analgesic and antipyretic properties--commonly known as aspirin-like drugs--have been used in equine medicine for almost 100 years. These non-steroidal anti-inflammatory drugs (NSAIDs) may be classified chemically into two groups; the enolic acids such as phenylbutazone and carboxylic acids like flunixin, meclofenamate and naproxen. All NSAIDs have similar and possibly identical modes of action accounting for both their therapeutic and their toxic effects. They block some part of the cyclo-oxygenase enzyme pathway and thereby suppress the synthe...
van Loon JPAM, Van Dierendonck MC.Objective pain assessment is important to guide and tailor therapy in clinical practice. This study describes the clinical applicability and validity of two pain scales, the Composite Pain Scale (CPS) and the Equine Utrecht University Scale for Facial Assessment of Pain (EQUUS-FAP) in horses with orthopaedic trauma or after orthopaedic surgery. A cohort follow-up study was performed using 77 adult horses (n=43 with orthopaedic trauma or injury; n=34 controls). Composite and facial expression-based pain scores were assessed by direct observations of pairs of two independent observers. All horse...
Ferris DJ, Frisbie DD, McIlwraith CW, Kawcak CE.Medications are frequently employed to treat intra-articular (IA) problems in the performance horse. Actual usage of the different IA medications in horses is not available. Objective: To determine the most common usage of these medications, members of the American Association of Equine Practitioners (AAEP) were surveyed. Methods: An email link to an online survey was electronically sent to 6305 AAEP members and the responses tabulated and analysed with a logistic regression model. Results: A total of 831 survey responses were submitted and tabulated. Eighty per cent of the respondents indicat...

Methods: Randomized clinical trial. Methods: 165 foals. Methods: Foals were randomly assigned to 1 of 2 groups (hyperimmune plasma or nontreated controls). Foals with failure of passive transfer (FPT) of immunity were treated with hyperimmune plasma and evaluated as a third group. Foals that received plasma were given 950 ml between 1 and 10 days of age and between 30 and 50 days of age. A tracheobronchial aspirate was obtained from fo...
Davidson EJ.Lameness examination is commonly performed in the athletic horse. A skilled lameness diagnostician must have keen clinical and observational skills. Evaluation starts with a detailed history and thorough physical examination. Next, gait evaluation in the moving horse is performed. Lame horses have asymmetrical body movement due to unconscious shift of body weight. Recognition of the resultant head nod and pelvic hike is the basis for lameness diagnosis. Lameness identification is enhanced by circling, limb flexions, and riding. Most lame horses do not exhibit pathognomonic gait characteristics...
Sanchez LC, Robertson SA.Currently, approaches to pain control in horses are a mixture of art and science. Recognition of overt pain behaviours, such as rolling, kicking at the abdomen, flank watching, lameness or blepharospasm, may be obvious; subtle signs of pain can include changes in facial expression or head position, location in the stall and response to palpation or human interaction. Nonsteroidal anti-inflammatory drugs (i.e. phenylbutazone, flunixin meglumine and firocoxib), opioids (i.e. butorphanol, morphine and buprenorphine) and α2 -adrenergic agonists (i.e. xylazine, detomidine, romifidine and medetomid...
Schott HC.PPID in older equids has become a major health concern of horse owners. In response, equine practitioners have made greater efforts at understanding, diagnosing, and treating this disorder. Although PPID is recognized to be a different form of pituitary-dependent hyperadrenocorticism than is seen in canine or human patients, relatively little is known about the pathophysiology and natural progression of the disease. At present, the diagnosis is best supported by manifestation of characteristic clinical signs and endocrinologic test results, preferably a supportive DST result. Treatment must fo...
Hughes LA, Pinchbeck G, Callaby R, Dawson S, Clegg P, Williams N.Antimicrobial use is known to select for the emergence of resistant strains of bacteria; therefore prudent use in both human and veterinary medicine is essential to preserve their efficacy. Objective: To characterise antimicrobial prescribing patterns in UK equine practice and evaluate factors associated with prescribing. Methods: A postal questionnaire including 4 clinical scenarios was sent to 740 veterinary surgeons that treat horses. Data were collected on the clinician, their practice and sources of information regarding antimicrobials and their use. Multivariable logistic regression anal...
Schauvliege S, Cuypers C, Michielsen A, Gasthuys F, Gozalo-Marcilla M.To summarize the different methods used to assess sedation and/or adjust the dose or administration rate of alpha-2 agonists in horses and to propose an algorithm to adjust the administration rate of a constant rate infusion of an alpha-2 agonist in horses. Methods: PubMed and Web of Science; search terms: horse, sedation and score. Conclusions: Most authors distinguish between sedation depth, sedation quality and degree of ataxia. These three features are evaluated using scoring systems similar to those classically used to assess pain, i.e. simple descriptive scales, numerical rating scales (...

Methods: Retrospective data analysis. Unassigned: In total, 1416 horses undergoing anaesthesia between May 2010 and December 2013. Methods: Patient information and details of the anaesthetic, recovery period and immediate complications were extracted from an archiving database. Statistical evaluation of factors affec...
Geddes LA, Tacker WA, Rosborough JP, Moore AG, Cabler PS.Electrical ventricular defibrillation of heavy subjects (over 100 kg body weight) is uncommon for the human or any animal species. This paper reports trans-chest ventricular defibrillation of subjects ranging in weight from 2.3 to 340 kg using conventional defibrillation current (heavily damped sine wave) of 0.3-30 ms duration. It was found that a body weight-to-electrical-shock strength relationship exists and can be expressed in terms of either electrical energy or peak current. For the duration of current pulse used clinically (3-10 ms), the relationship between energy requirement and body ...
Ortiz-Rodriguez JM, Anel-Lopez L, Martín-Muñoz P, Álvarez M, Gaitskell-Phillips G, Anel L, Rodríguez-Medina P, Peña FJ, Ortega Ferrusola C.Testicular function is particularly susceptible to vascular insult, resulting in a negative impact on sperm production and quality of the ejaculate. A prompt diagnosis of testicular dysfunction enables implementation of appropriate treatment, hence improving fertility forecasts for stallions. The present research aims to: (1) assess if Doppler ultrasonography is a good tool to diagnose stallions with testicular dysfunction; (2) to study the relationship between Doppler parameters of the testicular artery and those of sperm quality assessed by flow cytometry and (3) to establish cut off values ...
Wilmink JM, van Weeren PR, Stolk PW, Van Mil FN, Barneveld A.The histological aspects of second-intention healing were studied in 5 horses and 5 ponies. Biopsies were taken weekly from standardised wounds on the metatarsus and femoral biceps muscle of one horse and one pony. Sections were stained to enable cell counting and the detection of DNA synthesis, fibrin, smooth muscle actin (SMA), collagen, and bacteria. In the ponies, the number of polymorphonuclear leucocytes (PMNs) was high during the first 3 weeks and subsequently decreased rapidly. In the horses, the initial number of PMNs was lower, but remained persistently elevated during the evaluation...
Leadon D, Waran N, Herholz C, Klay M.Enormous numbers of horses are transported locally, nationally and internationally every year. National legislation and international guidelines set standards for the health and welfare of animals during transport. As a consequence, equine clinicians have major responsibilities in safeguarding the horse industry against the spread of disease and in being aware of the problems inherent in horse transport. The authors explore road, sea and air transport and their effect on horses. Various types of road transport are available and there are various sources of impact on horses. These include loadi...
Loomis PR.Clinical reproduction in the horse more closely parallels human clinical reproduction than in other domestic farm animals. Horse breeders rarely include fertility as a selection criterion when making mating decisions; in most breeds, there is no licensing or approval of stallions. This has led to a significant number of stallions in the breeding pool that possess desirable performance traits but are subfertile for a variety of reasons, some of them genetically transmitted between generations. Therefore, semen characteristics can vary greatly among stallions within the breeding population. A ch...
Martens A, De Moor A, Vlaminck L, Pille F, Steenhaut M.Ninety-five horses with sarcoids were subjected to three types of treatment: surgical excision (conventional or carbon dioxide laser), cryotherapy or local BCG vaccination. The type of treatment was selected on the basis of the size, location and clinical appearance of the tumours. The choice between conventional and laser excision was empirical. A successful outcome was obtained in 11 of 14 (79 per cent) of the horses treated by cryosurgery, 18 of 27 (67 per cent) treated by BCG vaccination, 18 of 22 (82 per cent) treated by conventional excision, and 20 of 28 (71 per cent) treated with a car...
Spiess BM.Equine recurrent uveitis (ERU) has always been and still is an important disease with a significant impact on the horse industry in Europe, with a prevalence of 8-10%. The need to understand and manage the disease has spurred the development of veterinary ophthalmology in general, although the aetiology of the disease remains the subject of intense discussion. It is most probably an autoimmune disease triggered, at least in Europe, in the majority of cases by Leptospira spp. The therapy of ERU has evolved over the centuries from various methods of bloodletting to rational medical therapy using...
Lorena SE, Luna SP, Lascelles BD, Corrente JE.The objective of this study was to assess the use of analgesics, describe the attitudes of Brazilian veterinarians towards pain relief in horses and cattle and evaluate the differences due to gender, year of graduation and type of practice. Methods: Prospective survey. Methods: Questionnaires were sent to 1000 large animal veterinarians by mail, internet and delivered in person during national meetings. The survey investigated the attitudes of Brazilian veterinarians to the recognition and treatment of pain in large animals and consisted of sections asking about demographic data, use of analge...
de Loës M.A prospective study of acute injuries from sports and physical exercise was carried out during 1 year in a total population of a municipality with 31,620 inhabitants. The medical treatment and the services required for the injuries have been calculated and related to the total consumption of medical care in the municipality. A total of 571 injuries (17% of all injuries) occurred in 28 different sports: 65% of the injured were males. Sports injuries accounted for 3% of all acute visits and there were altogether 1,083 outpatient visits, which yields a mean of 1.9 visits per injury. Related to th...
Rubio-Martínez LM, Cruz AM.Regional limb perfusion involves administration of an antimicrobial solution into the vasculature of a selected portion of the limb that has been isolated from the systemic circulation by controlled application of a tourniquet. The technique provides high antimicrobial concentrations in the region of interest and greatly contributes to the elimination of infection.
Knottenbelt DC.This article discusses the main treatments for sarcoid and the specific difficulties of these. It explains to some extent why the frustrations of a condition for which there is no single treatment option have led to the burgeoning of an industry of irrational treatments. The factors that need to be considered before selecting an option for treatment are wider than is the case in most other disease entities as a result of the complexity of the condition, its variable phenotypes, and the individual perceptions and experiences of both veterinarians and owners.
Revenaugh MS.Veterinarians have begun using extracorporeal shock wave therapy (ESWT) for treatment of osteoarthritis (OA) in horses, although relatively little information has been published about its efficacy or mechanism of action. As a clinician, it can be difficult to know if and when ESWT should be recommended. Case studies in which ESWT is used to treat advanced OA in horses are discussed. ESWTseems to be a valuable adjunct for management of equine OA. It is the purpose of this article to discuss indications and techniques as well as to share clinical experiences using ESWT in the treatment of OA in ...
Lesimple C, Fureix C, Biquand V, Hausberger M.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...
Wilson JM, McKenzie E, Duesterdieck-Zellmer K.To define which biologic, electrophysical and other modalities are used in horses for injury or performance issues, a questionnaire regarding 38 modalities was distributed to eight veterinary groups. A total of 305 complete or partial responses were obtained from over 10 geographic regions; 75.4% from private equine practice or regional private equine referral hospitals, 14.1% from university teaching hospitals or satellite clinics, 8.2% from private mixed animal practice, and 2.3% from veterinary rehabilitation centers. The majority of respondents were located in the USA (60%), Europe (25.6%)...
Oosterlinck M, Pille F, Huppes T, Gasthuys F, Back W.Modern pressure plates (PP) could be an alternative to traditional force plates (FP) for quantitative equine gait analysis, thereby providing the clinician with objective data on the horse's gait while unravelling the loading of different regions of the hoof during the stance phase. The aim of this study was to determine whether a stand-alone PP allows reliable measurement of gait kinetics, compared to simultaneously recorded FP variables. Six sound Warmblood horses were walked and trotted over a combined PP and FP system for collection of a set of five valid kinetic measurements for each fore...
van Dierendonck MC, Burden FA, Rickards K, van Loon JPAM.Objective pain assessment in donkeys is of vital importance for improving welfare in a species that is considered stoic. This study presents the construction and testing of two pain scales, the Equine Utrecht University Scale for Donkey Composite Pain Assessment (EQUUS-DONKEY-COMPASS) and the Equine Utrecht University Scale for Donkey Facial Assessment of Pain (EQUUS-DONKEY-FAP), in donkeys with acute pain. A cohort follow-up study using 264 adult donkeys ( = 12 acute colic, = 25 acute orthopaedic pain, = 18 acute head-related pain, = 24 postoperative pain, and = 185 controls) was performe...
Pan Z, Granger DA, Guérin NA, Shoffner A, Gabriels RL.We aimed to determine whether results of our prior randomized control trial [RCT; NCT02301195, (1)] of Therapeutic Horseback Riding (THR) for children and adolescents with autism spectrum disorder (ASD) could be at a different riding center and if treatment effects also included differences in the expression of associations between problem behavior and the activity of the hypothalamic-pituitary-adrenal (HPA) axis. Participants with ASD ( = 16) ages 6-16 years were randomized by nonverbal intelligence quotient to either a 10-week THR group ( = 8) or no horse interaction barn activity (BA) cont...
