Analysis of high frequency vibrations and heat impact on human hands

Abstract

Abstract. This article describes combined impact of ultrasound and heat therapies on patients with rheumatoid arthritis, systemic scleroderma and Raynaud's syndrome. Theoretical background of ultrasound and thermal effect was analyzed and described. Flexibility, strength and temperature of subjects' wrists and hands were investigated using thermographic camera, dynamometer, and physiological indicators. Investigation results were analyzed and demonstrated in graphs.
