Manual techniques in horse research encompasses a variety of hands-on methods used to assess and influence the musculoskeletal system of the animal. These techniques include massage, chiropractic adjustments, and stretching exercises, among others. They are applied to address issues related to muscle tension, joint mobility, and overall physical comfort. Practitioners of manual techniques may aim to enhance range of motion, reduce discomfort, and support rehabilitation processes. The application of these techniques requires a detailed understanding of equine anatomy and biomechanics. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, effects, and potential benefits of manual techniques in equine care and rehabilitation.
Pieroni C, Grassi A, Pantoli M, Berretti M, Messina S, Giovannini C, Lubas G, Diamanti D.The erythrocyte sedimentation rate (ESR) is a widely used diagnostic assay in human medicine but nowadays poorly applied in veterinary medicine. This test measures the speed (millimeters per hour) at which red blood cells settle in a whole anticoagulated blood tube. In human medicine, high ESR values are associated with various disorders, including infections, rheumatoid arthritis, oncologic diseases, and other inflammatory conditions. The ESR can also be influenced by some factors such as age and gender. In veterinary medicine, the ESR with the Westergren manual method was almost forgotten ov...
Keller P, Vanwesenbeeck I, Hudders L, Decloedt A.Complementary and alternative veterinary medicine (CAVM) is becoming increasingly popular in horses. Online, cross-sectional survey in 1532 horse owners. Attitude towards CAVM, subjective norms, perceived behavioural control and intention for future CAVM use were measured based on the theory of planned behaviour. Structural equation modelling was performed to characterize factors influencing intention to use CAVM. Past use of CAVM, predominantly manual therapies and herbal supplements, was reported by 72.5% of all participants. Frequently reported indications were improving horse's well-being,...
Merrifield-Jones M, Tabor G, Williams J.Back pain is a significant factor for horses and is challenging for professionals to diagnose, with assessment frequently using subjective tools such as manual palpation. Reliable and valid objective measures are required and use of a pressure algometer (PA) has been investigated as an assessment tool; however, it has limitations, and other more realistic methods may be better suited for the task. The aim of the study was to establish inter- and intra-rater reliability for PA, FlexiForce Sensor (FFS), and manual palpation for equine epaxial soft tissue, measuring mechanical nociception thresho...
Haussler KK.Manual therapies involve the application of the hands to the body, with a diagnostic or therapeutic intent. Touch therapies, massage, joint mobilization, and manipulation are all critical components in the management of muscular, articular, and neurologic components of select injuries in performance horses. Musculoskeletal conditions that are chronic or recurring, not readily diagnosed, or are not responding to conventional veterinary care may be indicators that manual therapy evaluation and treatment is needed.
Goff LM, McGowan CM, Condie P, Jasiewicz J, van Weeren R.Diagnosis of sacroiliac dysfunction in horses includes manual motion palpation of the equine ilium and sacrum. Motion of the ilium and sacrum during manual force application to the equine pelvis has been measured previously in vitro. The aim of this study was to measure the amount and direction of motion in vivo, including comparison of bone-fixated and skin-mounted inertial sensors. Sensors were skin-mounted over tuber sacrale (TS) and third sacral spinous process of six Thoroughbred horses and later attached via Steinmann pins inserted into the same bony landmarks. Orientations of each TS ...
Pirie CG, Alario AF, Barysauskas CM, Gradil C, Uricchio CK.Corneal thickness measurements of the equine globe using spectral-domain optical coherence tomography (SD-OCT) have not been reported. Objective: To determine corneal thickness measurements and the intra- and interoperator reliability of a portable SD-OCT device in equine eyes. Methods: Prospective observational study. Methods: Horses free of ocular disease were used for this study. Gentle manual restraint, in combination with detomidine hydrochloride and a head stand, were employed to ensure proper animal positioning. Corneal pachymetry measurements were obtained from both eyes of each animal...
Haussler KK.Manual therapy includes a diverse array of techniques, such as touch therapies, massage, physical therapy, osteopathy, and chiropractic, that were originally developed for use in humans and have been gradually applied to horses. All forms of manual therapy have variable reported levels of effectiveness for treating musculoskeletal issues in humans, but mostly only anecdotal evidence exists in horses. This article explores the scientific literature for evidence of efficacy, safety, and common mechanisms of action of the different forms of manual therapies for potential use in managing acute or ...
Wolf L.The locomotor system requires normal movement for normal function. Movement restrictions of soft tissues and joints stimulate nociceptive pathways in the corresponding vertebral segment. Reflex-induced alterations of sensory and motor neuron activity within the segment lead to detrimental changes within many of the tissues associated with and distant from the area. Manual therapy is utilized in both diagnosis and treatment of tissue and joint movement restrictions. Early recognition and treatment of dysfunction in the equine athlete prevents permanent pathology and facilitates performance exce...
May KA, Pleasant RS, Howard RD, Moll HD, Duesterdieck KF, MacAllister CG, Bartels KE.Holmium:yttrium-aluminum-garnet (Ho:YAG) laser lithotripsy was attempted in a mare and a gelding with calculi in the urinary bladder. The procedure was unsuccessful in producing adequate fragmentation of the calculi. In the gelding, pulsed dye laser lithotripsy was subsequently used to fragment the urolith. Manual removal of the urolith via the urethra was performed in the mare.
Nikolakopoulos E, Kindahl H, Gilbert CL, Goode J, Watson ED.Mating has been shown in many species to provoke the release of oxytocin (OT). In our study, various stimuli were applied to mares to study release of OT and prostaglandin F(2alpha) (PGF(2alpha)) associated with mating. Blood samples were collected from mares around the time of teasing both in oestrus and dioestrus and at mating. For comparison, blood samples were also collected at the time of manual manipulation of the genital tract and after intrauterine infusion of 500 ml phosphate buffered saline (PBS). Additional samples were collected 16 to 18 h after mating. Mating caused a significant ...
Macpherson ML, Reimer JM.Twin pregnancy in the mare causes economic loss. Early transrectal ultrasonographic detection of twins and manual crush of one embryonic vesicle is the method of choice for managing equine twins (90% success rate). Transcutaneous and transvaginal ultrasound-guided twin reduction techniques are described for twin pregnancies that advance beyond 25 days of gestation. Reported success rates for the ultrasound-guided procedures are 50% and 20%, respectively.
Kudlac E, Grygar J.The frequency of double ovulation and the chances of twin pregnancy in the mare are presented with reference to the relevant literature. A novel manual technique for reducing the embryo number from two to one is introduced and illustrated by ultrasonographic images.
Love CC, McDonnell SM, Kenney RM.A Thoroughbred stallion with erectile dysfunction following paraphimosis was managed to allow consistent ejaculation. Ejaculation was elicited in this stallion by applying manual stimulation to the base of the penis. This technique allowed consistent ejaculation, and the stallion was able to return to natural service. Historically, stallions with this degree of penile dysfunction have been considered incapable of ejaculation and unable to continue as breeding animals.
McDonnell SM, Pozor MA, Beech J, Sweeney RW.A 9-year-old atactic breeding stallion was trained to ejaculate, with only manual stimulation, while standing on the ground. Ejaculates obtained yielded fertile semen with morphologic and motility characteristics within the range for normal stallions. This method extended the breeding life of a stallion unable to mount a live or dummy mare or to ejaculate into an artificial vagina while standing on the ground.
Freeman DE, Orsini JA, Harrison IW, Muller NS, Leitch M.Of 147 horses treated for umbilical hernias over a 13.5-year period, 13 horses (8.8%) developed complications in association with umbilical defects. Six horses had intestinal incarceration; the incarceration was reduced manually in 3 horses before admission, resolved without treatment in 2 others, and was surgically reduced in one. Herniorrhaphy was performed on 4 of the 5 horses in which the incarceration did not require surgical reduction, and the fifth was managed conservatively. A horse with a parietal hernia and a horse with intestinal stragulation were treated surgically; in the latter, ...
Klide AM.Fifteen horses with chronic back pain for 1/2 to 9 years, who could not function normally, who did not obtain any lasting improvement from other previous treatments, were treated with acupuncture. The treatments were 20 minutes of manual acupuncture. The average number of treatments was 7.9 times administered at weekly intervals. After the acupuncture treatments were completed, 13 of the 15 horses were able to function normally.
