FOR EQUINE<br />

PROFESSIONALS<br />

| E X A M I N E | I D E N T I F Y | D I A G N O S E |


Every Equine Practitioner should have IR:<br />

an invaluable <strong>to</strong>ol for equine diagnosis<br />

Infrared imaging is a widely proven technology, known<br />

for both extreme sensitivity and high reliability.<br />

As a diagnostic <strong>to</strong>ol, thermal imaging is one of<br />

the most innovative, non-invasive modalities<br />

available <strong>to</strong> the veterinarian.<br />

Stressed tissue often presents as a thermographic<br />

abnormality prior <strong>to</strong> becoming structurally damaged.<br />

A thermal exam provides highly accurate<br />

diagnostic information that can enable the<br />

veterinarian <strong>to</strong> detect, confirm, and document<br />

many problems BEFORE the onset of serious injury.<br />

As prey animals, horses have a highly evolved<br />

instinct <strong>to</strong> mask pain and lameness in order <strong>to</strong><br />

appear less vulnerable in the wild. This can make<br />

diagnosis all the <strong>more</strong> challenging for the practitioner.<br />

Over the years improved technology, extensive<br />

clinical research and experience have brought<br />

thermography <strong>to</strong> a level which provides the veterinary<br />

professional a newfound ability <strong>to</strong> locate medical<br />

problems faster and proactively<br />

IN CLINICAL PRACTICE, EQUINE<br />

THERMOGRAPHY CAN:<br />

• Provide a highly sensitive, early indica<strong>to</strong>r of subtle<br />

circula<strong>to</strong>ry changes in soft tissue<br />

• Reveal inflamma<strong>to</strong>ry reactions in joints and tendons<br />

from two <strong>to</strong> six weeks prior <strong>to</strong> the clinical<br />

appearance of lameness<br />

• Allow the veterinarian <strong>to</strong> visualize neuro-vascular<br />

changes including the effect of vaso-active substances.<br />

LOCATING THE INJURY<br />

3 Steps <strong>to</strong> Equine Thermography<br />

1 Understanding<br />

Equine <strong>Thermal</strong><br />

<strong>Imaging</strong><br />

THERMAL SYMMETRY IS THE RULE<br />

• Changes of 1 degree centigrade or<br />

<strong>more</strong>, over 25% of the comparable<br />

ana<strong>to</strong>mic area are cause for further<br />

investigation.<br />

UNDERSTANDING ARTIFACTS<br />

• Clean body surface<br />

• Uniform hair coat<br />

• Feet picked out<br />

• His<strong>to</strong>ry of recent injections,<br />

therapy, medications, etc.<br />

• Has the horse recently been wrapped<br />

• Any evidence of dermatitis, poultice<br />

or blister on the skin<br />

• Evidence of clipping or hair loss<br />

• Scarring or areas of edema present<br />

2<br />

Implementing<br />

Equine <strong>Thermal</strong><br />

<strong>Imaging</strong> in Your<br />

Practice<br />

• Perform after physical exam<br />

• 10 – 15 minutes <strong>to</strong> complete<br />

• Learn normal vascular patterns<br />

• Use the horse as its’ own control<br />

• Be aware of potential artifacts<br />

• Focus on recognition of pathological<br />

patterns of heat - don’t<br />

worry <strong>about</strong> absolute<br />

temperatures.<br />

Achieve a<br />

Successful Diagnosis<br />

As part of the complete examination<br />

thermal imaging can be a defining <strong>to</strong>ol<br />

in making an accurate diagnosis<br />

Equine thermal imaging is a professional<br />

diagnostic modality that gives the<br />

veterinary professional the ability <strong>to</strong><br />

accurately measure, access and document<br />

changes in circula<strong>to</strong>ry patterns.<br />

The result is an enhanced opportunity<br />

for early intervention and therapy and<br />

a chance <strong>to</strong> prevent crippling and<br />

debilitating injuries.


Identify problems BEFORE they become<br />

serious complications or injuries<br />

Clinical evaluations have shown proven results. Here are just a few examples of how equine thermography<br />

can identify clinical problems early on before serious complications occur.<br />

INFRARED SUCCESS STORIES<br />

Identifying the Causes of Diminished<br />

Performance in Equine Practice<br />

Jim Waldsmith , DVM, The Equine Center<br />

Many horses are presented <strong>to</strong> our practice with a request <strong>to</strong><br />

define subtle changes in the horse's gait which are believed<br />

<strong>to</strong> be associated with a decrease in the level of the horse's<br />

athletic ability.<br />

On clinical exam these horses are many times found <strong>to</strong> be<br />

"body sore" resenting flexion and palpation in several areas<br />

of their body. The lameness has not progressed <strong>to</strong> a head<br />

bob or hip hike that can be blocked, yet the owner or trainer<br />

is concerned that stress or injury exists that will effect the<br />

horse's future performance.<br />

In many of these cases the areas of pain and inflammation<br />

are difficult <strong>to</strong> define and document clinically, and the use<br />

of systemic anti-inflamma<strong>to</strong>ry medication is considered.<br />

The risk in this therapeutic scenario is that symp<strong>to</strong>ms may<br />

be masked, and the source(s) of the diminished performance<br />

remain unknown potentially leading <strong>to</strong> subsequent breakdown<br />

in the horse.<br />

After a complete clinical exam we find thermal imaging<br />

allows a quick and noninvasive assessment of the entire<br />

horse's body. Frequently areas of hoof imbalance, joint<br />

inflammation and abnormal tack wear can all be quickly<br />

identified. By simultaneously identifying and treating all<br />

areas of abnormality and inflammation the horse's athleticism<br />

is improved and risk of further injury diminished.<br />

We have found this pro<strong>to</strong>col <strong>to</strong> be very rewarding in<br />

our practice producing both client satisfaction and<br />

improvement in the athletic health of our equine patients.<br />

The Use of Thermography<br />

in Equine Medicine<br />

Tracy Turner , DVM, MS, Diplomate ACVS<br />

In equine practice, thermography can detect inflamma<strong>to</strong>ry<br />

changes well in advance of other modalities, many times up<br />

<strong>to</strong> two weeks prior <strong>to</strong> the onset of clinical lameness.<br />

With tendonitis, a detectable rise in temperature occurs<br />

prior <strong>to</strong> evidence of pain and swelling. As tendons heal,<br />

temperatures become <strong>more</strong> uniform but remain elevated,<br />

meaning thermal changes correlate well <strong>to</strong> structural<br />

reorganization. In cases of capsulitis/synovitis, as the joint<br />

becomes inflamed, the thermal pattern reveals an oval<br />

area of inflammation just over the joint.<br />

A particularly valuable use of Thermography is in detecting<br />

muscle injury. In addition <strong>to</strong> locating inflammation within a<br />

muscle or muscle group, atrophy can be detected before it<br />

is clinically apparent, presenting as areas of consistent<br />

decreased circulation and regional cooling when compared<br />

<strong>to</strong> the opposite side. Likewise, nerve injury due <strong>to</strong> direct<br />

trauma, secondary injury, or any disease that can affect blood<br />

flow can also be visualized with thermography.<br />

The uses in equine practice are endless:<br />

• Pre-purchase examinations,<br />

• Saddle fit,<br />

• A training aid <strong>to</strong> avoid injury<br />

(e.g., detecting hot shins before they buck),<br />

• Hoof balance and concussion injuries<br />

• Laminitis detection, and other foot diseases.<br />

• Capsulitis /synovitis in joints,<br />

• Tendonitis, (following tendon healing after injury),<br />

• Detecting muscle injury, atrophy and strain<br />

• Circula<strong>to</strong>ry changes before and after exercise.<br />

By utilizing <strong>Thermal</strong> <strong>Imaging</strong>, on a regular basis, in my<br />

clinical practice I find I am <strong>more</strong> able <strong>to</strong> efficiently and<br />

effectively locate both clinical and sub-clinical disease.<br />
