EQUINE IMAGING

Detecting, Analyzing and Reporting Equine Physiology Through Infrared Imaging

Thermetry is an adjunct tool that analyzes infrared data within zones relative to muscle and joint activity.  Our system measures thousands of infrared data points within regions of superficial, intermediate muscles and joints to quantify functional asymmetry related to the effects of compensation patterns - systematic and adaptive overuse of certain muscle groups and joints due to physical predispositions (e.g. tension, weakness, injury, limited flexibility, pain).  The application intelligently detects muscle regions of the entire equine anatomy and measures infrared activity within those regions. Thermetry also integrates our premium Thermal Biomechanics™ Technology which algorithmically simulates the effects of compensatory patterns on the kinetic chain by calculating the increased demands on muscles, joints and ligaments as well as the influences on posture, balance and  mobility.  Automated reports are generated that include anatomical illustrations, graphs and charts in an organized, user-friendly format for quick and easy referencing. 

THE PROCESS

INFRARED RESEARCH

Even though humans are bipeds and equine are quadrupeds, both mammals have quite comparable musculoskeletal systems that can be analyzed using similar tools and methodologies [1].  Seventy percent of all heat emitted from the body is produced by muscle activity [2].  As a muscle contracts, blood flow increases and stored ATP is broken down into energy [3]. This increase of oxygenation and metabolic activity generates heat which is emitted through the skin in proximity of the activated muscle [4].   Infrared imaging is a precise way to detect anatomical regions and measure the thermal emissions of muscle activity [5]. Equine IR measures infrared data within regions of superficial and intermediate muscles to quantify functional asymmetry related to the effects of compensation patterns - systematic and adaptive overuse of certain muscle groups due to physical predispositions (e.g. tension, weakness, injury, limited flexibility, pain) [6].  Based on biology principles of bilateral symmetry and the use of infrared imaging to quantify asymmetry [7], each muscle region is compared to its symmetrical counterpart to identify and measure thermal asymmetry.  Automated reports are generated to 1) quantify functional asymmetry, 2) analyze the increased demands on muscles, ligaments and joints and 3) calculate the potential effects on posture, balance, and mobility.
