Detecting, Analyzing and Reporting Muscle and Joint Activity Through Infrared Imaging

Thermetry is an intelligent adjunct tool for professionals to measure infrared data related to muscle and joint activity and to maximize their decisions about treatment and services options through objective, quantifiable feedback.  Our system measures thousands of infrared data points within regions of superficial muscles, intermediate muscles and joints to quantify functional asymmetry related to the effects of compensation patterns - systematic and adaptive overuse of certain muscles and joints due to physical predispositions (e.g. tension, weakness, injury, limited flexibility, pain).  The application intelligently detects anatomical regions anywhere on the human body and precisely measures activity within those regions.  Our system also integrates our 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.

Seventy percent of all heat emitted from the body is produced by muscle activity [1].  As a muscle contracts, blood flow increases and stored ATP is broken down into energy [2].  This increase of oxygenation and metabolic activity generates heat which is emitted through the skin in proximity of the activated muscle [3].   Infrared imaging is a precise way to detect anatomical regions and measure the thermal emissions of muscle and joint activity [4].  Osteopathy 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) [5].  Based on biology principles of bilateral symmetry and the use of infrared imaging to quantify asymmetry [6], data from key physiological zones are compared to symmetrical counterparts to identify and measure thermal asymmetry.  Automated reports are generated to a) quantify functional asymmetry, b) analyze the increased demands on muscles, ligaments and joints and c) calculate the potential effects on posture, balance, and mobility.
