Thermography and Repetitive Stress Trauma: A Pilot Study

Abstract

Liquid crystal thermograms were used in this pilot study to produce “surface temperature gradient maps” of the forearms, wrists, and hands of persons with and without symptoms of cumulative stress trauma. In addition, individuals with other common wrist and hand dysfunctions, impairments, or maladies such as arthritis were included to evaluate possible confounding factors in these procedures. Bilateral comparisons were made of the thermograms of the upper extremities of each subject. Results indicate that temperature differences of 1 degree C. or greater between symmetric body parts, taken under correctly conducted procedures, may be interpreted as a positive indication of a definite and significant medical condition or trauma, including trauma produced by cumulative stress.
