Horseshoes are protective devices attached to the hooves of horses to enhance durability and performance. They are typically made from materials such as steel, aluminum, or composite materials and are designed to protect the hoof from wear and tear, provide traction, and support for various equine activities. The application of horseshoes, known as shoeing, is performed by a farrier and involves careful consideration of the horse's hoof anatomy, activity level, and environmental conditions. Horseshoes can be customized to address specific hoof health issues or performance needs. This page compiles peer-reviewed research studies and scholarly articles that explore the design, application, and impact of horseshoes on equine biomechanics, hoof health, and performance.
Turner TA.Navicular disease was diagnosed in 36 horses. Each horse was treated, using shoeing as the only major means of treatment. Phenylbutazone was used initially for 10 days after shoeing. Shoeing was designed to correct preexisting problems, enhance physiologic function of the foot, and ease breakover of the foot. The horses were evaluated over a period ranging from 12 to 54 months. The lameness improved in all horses. Thirty-one of the 36 horses treated were not lame when last evaluated. Shoeing was most effective when performed within 8 months of the first signs of lameness. Also, horses used for...
Ostblom LC, Lund C, Melsen F.Although the diagnostic criteria of navicular disease are generally accepted in practice, their limitations are recognised. However, the authors believe that navicular disease per se is reversible and that only secondary changes like adhesions to the deep flexor tendon or spur formations are irreversible. This hypothesis is supported by the results presented of the effect of the application of an egg-bar shoe, which caused permanent cessation of signs of navicular disease in more than 50 per cent of treated cases. The egg-bar shoeing technique can be usefully applied in practice.
Elvinge F.The question of the origin of the horse-shoe is reconsidered and China is pointed out as the site of origin. The theory is put forward that the Mongolian people living north of China and having constant fights with the Chinese have learnt the horseshoes with nails from the Chinese and that the Huns on their travel westwards have brought this type of horseshoe to Europa. The theory is substantiated from authoritative sources. The Chinese ministry of agriculture and forestry has given the information that horseshoes with nails have been used here for more than 2000 years. The possibility exists ...
Wilson AM, Pardoe CH.Studies on horseshoe materials have been limited to the analysis of kinematic data to determine slip times and distances, since equine force plate analysis is traditionally undertaken on a rubber-surfaced force plate. The purpose of this study was to modify a force plate for measuring ground reaction forces on a road surface and report preliminary data from the system. A steel-reinforced concrete top plate of 18 mm thickness and mass 23 kg, and a 12 mm thick top plate of 6 mm bituminous macadam wear coat (road surface) contained in a tray constructed of 2 mm thick steel, mass 21 kg, were const...
Brandstetter J, Stanek C, Hinterhofer C.The use of handmade particulate reinforced alloy horseshoes (MMC metal matrix composites) was tested in a field study on 15 riding and draught horses. All horseshoes have been tempered after having been manually forged and tested concerning their surface imperfection. Forging temperature ranged between 350 degrees and 420 degrees C. Horseshoes in series A consisted of particulate reinforced wrought alloy (22% Al2O3 in alloy matrix). 11 shoeing periods with a duration of mean = 49.7 days (sd = 13.6) were evaluated. Horseshoes in series B consisted of particulate reinforced foundry alloy (20% Si...
Curtis S, Ferguson DW, Luikart R, Ovnicek G.Several of the technical approaches applied to the foot overlap with regard to intent. Frog or solar support, for example, may be provided either to stabilize the distal phalanx within the hoof capsule or in an effort to unload regional pain arising from the solar surface of the foot. It is likewise obvious that some techniques such as lowering the heels to achieve phalangeal realignment and raising the heels to relieve deep digital flexor tendon tension are contradictory. In these instances, it is not that one technique is always correct but that differences exist among horses. Currently, it ...
Fürst A, von Salis B, Isenbügel E, Weishaupt M, Bertolla R, Geyer H.In the past few years marked changes in the field of farriery have been noted. In addition to the classical farrier, many new occupations concerned with hoof care have emerged, such as hoof trimmer, hoof technician, hoof orthopedist and hoof naturopath. Furthermore, a tremendous number of hoof protection systems have been developed, with an ever-increasing application to horses. However, regulations regarding alternative shoeing methods are insufficient and it is not clear, who governs the quality of the work of the individuals involved. Thus, a neutral authority composed of farriers and veter...
McGuigan MP, Walsh TC, Pardoe CH, Day PS, Wilson AM.Previous studies have implicated tension in the deep digital flexor tendon (DDFT) in the rotation of the distal phalanx (DP) after the breakdown of the dorsal laminae caused by laminitis. Howeveer, once the DP has rotated, the DDFT should become shorter, reducing the force it exerts on the DP. Objective: To compare DDFT force and ground reaction forces (GRFs) in normal ponies and ponies with rotation of the DP as a sequel to laminitis. Methods: Six normal ponies (Group 1) and 6 sound ponies with 6-13 degrees of rotation of the DP in relation to the dorsal hoof wall (Group 2) were assessed at t...
Rollot Y, Lecuyer E, Chateau H, Crevier-Denoix N.As critical locomotion events (e.g. high-speed and impacts during racing, jump landing) may contribute to tendinopathies, in vivo recording of gaits kinematic and dynamic parameters is essential for 3D reconstruction and analysis. Objective: To propose a 3D model of the forelimb and a ground reaction force recording shoe (GRF-S) for noninvasively quantifying tendon and ligament loads and strains. Methods: Bony segments trajectories of forelimbs placed under a power press were recorded using triads of ultrasonic kinematic markers linked to the bones. Compression cycles (from 500-6000 N) were ap...
Colles CM.This paper describes the application of foil strain gauges to the hoof wall, and the use of measuring equipment to monitor weightbearing and changes in hoof shape in shod and unshod horses. It concludes that the systems can detect hoof movement and that results are reproducible. It is also concluded that the use of a conventional nailed on iron shoe restricts flexion and spreading of the hoof wall at the ground surface, but has little effect on the degree of expansion of the heels of the foot.
Kane AJ, Stover SM, Gardner IA, Case JT, Johnson BJ, O'Brien MJ, Read DH, Ardans AA.To develop a standard technique for evaluation of racehorse shoes, to assess homotypic variation (interlimb variation) in shoe characteristics, and to determine whether shoe characteristics varied with age and sex. Methods: Cross-sectional study. Methods: Thoroughbred racehorses (n = 201) that died or were euthanatized at California racetracks between August 1992 and July 1994. Methods: Shoe characteristics were measured on horses examined after death. Percentage of agreement was used to compare shoe characteristics between limbs (homotypic variation). Using chi 2 analysis, shoe characteristic...
Mieszkowska M, Holak P, Zhalniarovich Y, Mieszkowski M, Domagalska-Stomska K.A sound knowledge of horseshoe impact on blood flow parameters is required for making shoeing decisions and selecting the most appropriate types of shoes. The aim of this study was to determine the effect of horse shoeing with egg bar shoes and shoes with wedge pads on blood flow parameters in the lateral palmar digital artery measured by Doppler ultrasound. The study was conducted on 16 horses divided into two groups. Horses from group 1 were shod with egg bar shoes. Horses from group 2 were shod with shoes with wedge pads. Doppler ultrasound parameters of the lateral palmar digital artery at...
Roepstorff L, Drevemo S.To further develop objective methods in the field of gait analysis a force-measuring horseshoe (FM shoe) has been developed. The ground reaction forces were determined by measuring the degree of displacement between the two solid parts of the shoe. This was done by three removable measuring units (MUs) that were equipped with strain gauges and placed in the toe and in each of the quarter parts. Before performing force recordings the sensors were calibrated with the actual MUs mounted on the shoe. This can be done in the field with a specially developed equipment. The shape of the signal genera...
Poochipakorn C, Sanigavatee K, Wonghanchao T, Huangsaksri O, Chanda M.Underrun heels are among the most hoof imbalances, causing poor performance in hoses. Several corrective shoeing protocols have been performed, but the outcomes have yet to be consistent. In this study, we proposed an alternative trimming protocol for managing underrun heels: strategic palmar trimming before conventional shoeing. Therefore, the current study aimed to investigate the potential of strategic palmar trimming before conventional shoeing for managing hoof imbalance in horses with underrun heels. Unassigned: Eleven affected horses were divided into control (5 horses with 14 defective...
Bark C, Reilly P, Weller R, Pfau T.Hoof care providers are pivotal for implementing biomechanical optimizations of the musculoskeletal system in the horse. Regular visits allow for the collection of longitudinal, quantitative information ("normal ranges"). Changes in movement symmetry, e.g., after shoeing, are indicative of alterations in weight-bearing and push-off force production. Ten Warmblood show jumping horses (7-13 years; 7 geldings, 3 mares) underwent forelimb re-shoeing with rolled rocker shoes, one limb at a time ("limb-by-limb"). Movement symmetry was measured with inertial sensors attached to the head, withers, and...
Caure S, Dendauw P, Thesee L, Villedey E, Malinvaud A, Cousty M, Prie V, Horan K, Weller R.There is a paucity of scientific data on the effect of shoeing on equine neck and back kinematics during locomotion over commonly used sand training surfaces. A better appreciation of how alterations at hoof-ground interface influence equine upper body movements is relevant for improving horse's health and performance. Our objectives were to determine the effects of different shoeing conditions on equine neck and back kinematics at walk and trot in straight line over sand. Two-dimensional kinematic video analysis was performed under seven shoeing conditions: front feet shod with aluminum shoes...
Colla S, Johnson JW, McGilvray KC, Zanotto GM, Seabaugh KA.Therapeutic shoeing for horses is used to affect the palmar angle (PA) of the distal phalanx. These changes may influence the strain on the distal interphalangeal joint collateral ligaments (DIJCLs). This cadaveric study aimed to assess DIJCL strain under varying loads and PA adjustments. Using 26 cadaver forelimbs, eight optical markers were placed on one DIJCL for strain measurement under five different loads (1000-5000 newtons) at a neutral PA, followed by PA increases of 2°, 4°, and 6° and decreases of -2° and -4°. The results indicate that increases in PA corresponded to significantl...
Aoun R, Ogunmola Z, Musso A, Taguchi T, Takawira C, Lopez MJ.The shift in vertical forces on the equine hoof surface by heart-bar, egg-bar, and wooden clog shoes can significantly impact gait kinetics. Hypotheses tested in this study were that vertical, braking, and propulsion peak force (PF) and impulse (IMP) are different while shod with heart-bar, egg-bar, open-heel, and wooden clog shoes, or while unshod, and the resultant ground reaction force vector (GRF YZ ) has the longest duration of cranial angulation with open-heel shoes followed by unshod, then egg-bar and heart-bar shoes, and the shortest with wooden clog shoes. Forelimb GRFs were recorded ...
Ennsmann LH, Licka TF.Most horses are used with horseshoes additionally supported by either dorsoabaxial or dorsal clips. The effects of such clips on bone density and shape of the distal phalanx are currently unclear. The aim of this study was to identify correlations between density and shape of the distal phalanx, comparing front hooves unshod or shod with standard shoes either with two dorsoabaxial clips or with a single dorsal clip. Researchers analyzed Oxspring radiographs of either the left or right front hoof from warmblood horses ( = 137) and ponies ( = 43) aged 3-28 years. The evaluation focused...
Gottleib K, Trager-Burns L, Santonastaso A, Bogers S, Werre S, Burns T, Byron C.Differences in horseshoe materials may have effects on gait that could change perceived esthetic qualities. Objective information regarding effects of shoeing on gait characteristics of horses is scant. The aim of this study was to determine differences in gait characteristics for horses under various experimental shoeing conditions (barefoot, aluminum shoes, steel shoes) on two surfaces (asphalt and soft footing) using body- and hoof-mounted sensors. We hypothesized that shoeing would affect hoof arc height during early (arc height a) and late (arc height b) swing phases but would not affect ...
Caure S, Miljak K, Dendaw P, Thesée L, Villedey E, Malinvaud A, Cousty M, Prié V, Horan K, Weller R.Effects of ground surface and hoof angles on equine cervical and thoracolumbosacral kinematics are poorly understood. However, the equine cervical and thoracolumbosacral areas present frequent lesions and he management of factors that might improve treatment and rehabilitation outcomes, such as ground surface and hoof angles, requires more investigation. Objective: Our objectives were to determine the influence of ground surface (asphalt versus sand) and a 3 degrees hind toe or heel elevation on cervical and thoracolumbosacral kinematics during walking and trotting. Methods: Six saddle horses ...
Siedler C, Zinkanel YM, Schramel JP, Peham C.The interaction between equine hooves and various ground surfaces is a critical factor for injury prevention and performance in modern equestrian sports. Accurate measurement of surface grip is essential for evaluating the effectiveness of different hoof protection systems. This study introduces the Vienna Grip Tester (VGT), a novel sensor-based device developed to quantify rotational resistance-an important parameter for assessing hoof-surface interaction. The VGT utilizes a torque wrench and spring-loaded mechanism to simulate lateral hoof movements under a standardized vertical load (~700 N...
Ferreira CMC, Simões BD, Marques EAS, Carbas RJC, da Silva LFM.Despite technological advancements in various industries, the equine sector still relies on old methods like horseshoeing. Although traditional, the industry is dynamic and well-funded. Therefore, there is a need to modernize these methods with more reliable and less invasive solutions for attaching horseshoes to horse hooves. There are currently several commercial adhesive solutions in the market specifically tailored to this application. In this work, the mechanical properties of two acrylic adhesives were characterized under quasi-static conditions. In the characterization process, tensile,...
