Thermographic diagnostics in equine back pain.
Infrared thermographic imaging (ITI) is the most sensitive objective imaging currently available for the detection of back disease in horses. It is, however, only a physiological study primarily of vasomotor tone overlying other superficial tissue factors. Interpretation requires extreme care in imaging protocol and in understanding the significance of altered sympathetic nervous tone and the sympathetic distribution. Most discussions on back pain have centered on nociception and inflammatory events. ITI provides information and localization for more significant than diagnosing areas of hot spots. Chronic back pain usually involves vasoconstriction at the affected sites and from ITI studies in man, we have an opportunity to appreciate chronic pain phenomena that involves non-inflammatory events. These occur commonly in horses, but are still seldom recognized and treated.
