Thermovision assessment of temperature changes in selected body areas after short-wave diathermy treatment

Abstract

The aim of this study is to provide the thermal imaging assessment of local and general surface temperature changes after short-wave diathermy treatment. The study group consisted of 26 women aged 19–24. The correct functioning of the thermoregulation system was determined by means of cold pressor and orthostatic tests. The subjects underwent short-wave diathermy treatment in the area of the right knee joint, and the body’s response was determined by thermovision using a ThermaCAM P640 thermal imaging camera manufactured by FLIR. Curves were recorded in a digital form (images with a resolution of 640 × 480 pixels) and analyzed with ThermaCAM ReporterTM software. In people with a properly functioning thermoregulation system, the short-wave diathermy treatment statistically significantly increased the body surface temperature on the posterior surface of the knee joint. On the front side, the surface temperature decreased. There were no changes in surface temperature in the other areas of the body studied. The results of thermal imaging studies confirmed the local nature of the action of short-wave diathermy. The recommendation to use a physical procedure should be preceded by an assessment of the body’s thermoregulation system level of function. Reactions to the prescribed physical treatment may be different in people with a disturbed autonomic system.
