Clinical examination in horses involves a systematic evaluation of the animal to assess its health status and identify any potential medical issues. This process typically includes a thorough physical assessment, which may cover observation of behavior and posture, palpation of body structures, auscultation of heart and lung sounds, and examination of the skin, eyes, and mucous membranes. Additional diagnostic tools such as thermography, endoscopy, or imaging techniques may be utilized to gather more detailed information. Clinical examination serves as a foundational step in veterinary diagnostics, aiding in the detection and management of diseases or injuries in horses. This page compiles peer-reviewed research studies and scholarly articles that explore methodologies, advancements, and findings related to clinical examination practices in equine medicine.
Peretti V, Satué K, Ciotola F, Cristarella S, De Majo M, Biondi V, D'Anza E, Albarella S, Quartuccio M.A 3-year-old Arabian mare underwent medical examinations due to the presence of abnormalities of the reproductive apparatus and stallion behavior (nervous temperament, aggressiveness, masculine attitude). During the clinical visit, an anovulvar distance shorter than normal was observed; moreover, vulvar lips were dorsally fused except for the lower neckline, showing a blind ending from which a penis-like structure protruded. The ultrasound examination revealed the presence of a cervix and corpus of a uterus, hypoplastic uterine horns, and small gonads with an echogenicity similar to a testis. ...
Riley CB, Aldrich ED, Pemberton SL, Mirza AA. A 9-year-old warmblood gelding with a history of chronic intermittent tachypnoea and dyspnoea was presented for evaluation and removal of a mass on the left side of the neck. A fibrous mass adherent to the left jugular vein developed and was removed surgically 6 weeks later, at which time the owner requested an evaluation of the cause of the persistent respiratory signs first noted on primary admission. Clinical findings included coarse lung sounds on thoracic auscultation, tracheal wheeze, and an abnormal trans-tracheal aspirate. These findings, in addition to the results of ultrasonographi...
Werpy N, Chapman K, Griffith L.When evaluating suspensory ligament branch splits, there is a discrepancy between high field MRI findings and weight bearing ultrasonographic imaging characteristics. In this descriptive and retrospective case series, ultrasonographic examination was performed on suspensory ligament branches with the limbs in weight bearing and non-weight bearing positions. Suspensory ligament branch splits were defined as linear regions of decreased echogenicity when imaged with the limb in a weight bearing position that increased in size and became anechoic with the limb in a non-weight bearing position. Thi...
Pringle J, Venner M, Tscheschlok L, Waller AS, Riihimäki M.Difficulty in detection of silent carriers of Streptococcus equi is a key reason for its continued spread to immunologically naïve groups of horses. Objective: To determine whether clinical examination, markers of inflammation, or serology differentiate silent carriers of S. equi in recovered comingled horses. Methods: Ninety-eight warmblood yearlings and 72 unaffected mares on a large breeding farm (outbreak A), 38 mature Icelandic horses at a riding stable (outbreak B), and 27 mixed breed horses at a boarding stable (outbreak C).

True CK, Dotzel AR.Oral endoscopy is a valuable addition to the equine dental examination process. It enables veterinarians to visualize subtle oral disorders and is a useful client education tool. There are several commercially available oral endoscopic systems on the market. Practitioners can also assemble their own systems. An oral endoscope is used to perform a thorough and systematic oral examination and to visualize normal oral structures as well as oral disorders. It is also used to guide instrument placement during oral surgeries and other dental procedures.
Earley ET, Reiswig JD.Odontoplasty (floating and occlusal equilibration) is the most commonly performed procedure in equine dentistry. From an anatomic perspective, an irregular occlusal surface, prominent cingula, transverse ridges, and enamel points all contribute to the function, form, and longevity of the equine cheek tooth. With limited reserve crown available and an average functional life range between 18 and 25 years, removal of tooth structure should be conservative. The authors consider a quality oral examination to be the most important dental procedure performed in the horse. Individual tooth evaluatio...
Saadi A, Dalir-Naghadeh B, Akbari H, Rashedi M, Mohammadi R.An 11-year-old Hanoverian gelding used for jumping was evaluated for gait abnormalities and hoof problems in the hindlimbs. Clinical examinations revealed signs consistent with shivers. A thyroid gland enlargement was noticed, baseline serum thyroid hormone (TH) concentrations were low, and a low response to thyrotropin-releasing hormone administration was observed. Hypothyroidism was suspected. The horse was treated with levothyroxine for 1 year. TH concentrations returned to the normal range by week 4 of treatment. Thirty weeks after the initiation of levothyroxine therapy, the gait abnormal...
Furr M, McKenzie H.Bloodstream infections (BSI) are common in sick foals and increase foal morbidity and mortality when they occur.

Rahnama S, Vathsangam N, Spence R, Medina-Torres CE, Pollitt CC, de Laat MA, Bailey SR, Sillence MN.Currently, there are no registered veterinary drugs for the treatment of endocrinopathic equine laminitis, and although this form of the disease is known to be caused by prolonged hyperinsulinaemia, the mechanism of insulin toxicity is unclear. One possibility is that high concentrations of insulin activate IGF-1 receptors (IGF-1R) in lamellar tissue, leading to uncontrolled cell proliferation and epidermal lamellar dysregulation. An equinized version of a human anti-IGF-1R therapeutic monoclonal antibody (mAb11) was generated to test this theory, using a modification of the prolonged euglycae...

Van Biervliet J.The practice of equine neurology has special challenges posed by the size of the animal being examined. Many diagnostic procedures routinely used in small animal practice are unsafe when applied to the equine patient or unavailable to the equine practitioner. Therefore, astute observation is the mainstay of making a neuroanatomic diagnosis, and detailed evidence on the deficits present may be difficult to obtain. Because clinical observation can sometimes be ambiguous and somewhat subjective, it is even more important to approach equine neurology from an evidence-based point of view. Here, suc...
Decloedt A, Verheyen T, De Clercq D, Sys S, Vercauteren G, Ducatelle R, Delahaut P, van Loon G.Horses are extremely susceptible to ionophore intoxication.

Archer DC, Proudman CJ, Pinchbeck G, Smith JE, French NP, Edwards GB.The clinical features of 71 cases in 70 horses in which part of the small intestine became entrapped in the epiploic foramen are described. The horses' sex, age and breed, the month during which they were affected, and whether they exhibited stereotypic behaviour were compared with the same variables in 1279 horses which suffered other types of surgical colic during the same period. Thoroughbred and thoroughbred cross horses were over-represented among the 70 affected horses. There was no age or sex predilection. Fifty-five (77.5 per cent) of the cases occurred between October and March and 15...
Despite some views to the contrary the working party of the Association of Veterinary Teachers and Research Workers considers that it has been demonstrated that it is possible to prepare guidelines for the recognition and assessment of pain in experimental animals. The detailed information readily available on species specific signs is limited and it has been particularly difficult to obtain such signs for the smaller mammals and for the non-mammalian species.
Kunz JR, Granella MCS, Mendes RP, Müller TR, Kau S, Fonteque JH.In developing and emerging countries, many people make a living from picking municipal solid waste to sell for reuse or recycling. These people depend on cost-effective transport vehicles like horse-drawn carts. It is indisputable that the general health of these horses not only plays a major economic role but is a welfare issue as well. Orodental disorders are likely to be of particular importance as they directly impair health, performance, and therefore influence animal welfare and income. However, studies investigating prevalence and distribution of orodental disorders in working horses ar...

Lloyd S, Soulsby EJ.This survey was performed to study the prevalence of infection with Onchocerca cervicalis in horses in the eastern United States. In the course of the survey, 121 horses, 1 mule and 1 donkey were examined. Microfilariae were recovered from 74 (61%) of the horses examined. All infected horses showed microfilariae of O cervicalis in the umbilical sample, 62 (84%) were infected in the eyelid and, in 36 (49%), microfilariae had invaded the eye. The mule was unifected and the donkey was infected with O cervicalis.
Germann SE, Richter M, Schwarzwald CC, Wimmershoff J, Spiess BM.A 6-year-old thoroughbred gelding was presented with a history of blepharospasm and opacity in the OS of 1 weeks' duration. Ophthalmic examination findings were consistent with acute uveitis in the OS, and traditional treatment was initiated with systemic antibiotics and anti-inflammatory drugs, topical mydriatics, and corticosteroids. During the total treatment period of 4 weeks response to treatment was weak and the horse developed further problems such as cellulitis of the right hind limb with fever and eventually weight loss and dependent edema. Blood work was indicative of liver disease. ...
García-López JM.Pain localized to the neck, back, and or pelvis can result in a profound effect on the horse's performance. These conditions can present with a varied and nonspecific set of clinical signs. A careful and thorough examination of these areas by means of physical examination, lameness evaluation both in hand and under saddle, diagnostic anesthesia, and the use of multiple imaging modalities in combination is often necessary to have an accurate prognosis. Medical and surgical management where appropriate of the conditions highlighted in this article are discussed as well as their individual progno...
Chotel F, Parot R, Durand JM, Garnier E, Hodgkinson I, Bérard J.The choice of first-line treatment for congenital varus equine clubfoot remains a controversial issue largely dependent on experience. In France, functional treatment predominates. In 1948, Ponseti proposed reducing the deformity with successive casts. Although cast treatment is a very old method, Ponseti's method is original because it is based on strict rules established from anatomic evidence. The goal is not to correct the apparent deformation, but on the contrary to impose a simultaneous supination and abduction of the foot. Once the calcaneopedal block has been derotated, percutaneous te...
Veeramachaneni DN, Moeller CL, Sawyer HR.Conventional light microscopic evaluation of a seminal ejaculate does not fully avail potential indicators of functional impairment in spermatozoal organelles. The technique of critical quantitative evaluation of morphologic features of individual structural components of spermatozoa at a light microscopic level in conjunction with critical qualitative evaluation of spermatozoal organelles at an ultrastructural level, as described in this article, is a valuable clinical tool. Compared with a battery of sperm function assays used in human andrology clinics, this relatively less expensive and si...

Twenty-four horses were diagnosed with cervical stenotic myelopathy, 5 with cervical vertebral stenosis, 7 with idiopathic ataxia, 3 horses had other causes of ataxia, and 20 were controls. The MR images were assessed for spinal cord intensity changes, presence of spinal cord compression...
Birks EK, Durando MM, McBride S.EIPH is a condition affecting virtually all horses during intense exercise worldwide. The hemorrhage originates from the pulmonary vasculature and is distributed predominantly bilaterally in the dorsocaudal lung lobes. As the condition progresses, the lung abnormalities extend cranially along the dorsal portions of the lung. An inflammatory response occurs in association with the hemorrhage and may contribute to the chronic sequela. Although conflicting opinions exist as to its affect on performance, it is a syndrome that is thought to increase in severity with age. The most commonly performed...
Hanson RR, Wright JC, Schumacher J, Baird AN, Humburg J, Pugh DG.To evaluate the seasonal influence, signalment, type of hay consumed, clinical examination findings, and outcome after surgery for horses with ileal impaction. Methods: A retrospective study. Results: Between 1988 and 1993, 28 horses had surgical correction of ileal impaction. There was a significantly higher rate of ileal impaction during the Fall (September-November, P = .0041 ). Mean duration of clinical signs of abdominal pain before referral was 15 hours. Transrectal palpation was used to localize the impaction in 11 horses. The ileal impaction was reduced by extraluminal massage aided by...
Kusano K, Ishikawa Y, Seki K, Kusunose R.Inflammatory airway disease (IAD) is a common cause of poor performance, interruption of training and premature retirement in racehorses. It is also reported that up to 80% of horses are affected at some point in the first years of training in UK and Australia. However, no studies with regard to the information on occurrence of IAD in Japanese Thoroughbred racehorses have been reported. To investigate the occurrence and the characteristics of IAD, epidemic research including endoscopic examination of the airway tract and trachea wash was conducted for Thoroughbred racehorses presenting coughs ...
