Influence of Ultrasonic Irradiation on Temperature and Blood Flow in Human Skeletal Muscle

Abstract

The circulatory response to ultrasonic irradiation of the upper limbs was measured under controlled conditions by venous occlusion plethysmography. Volumetric blood flow changes were related to temperature measurements in the treated tissues. Ultrasonic irradiation of the extremities was not found, per se, to be an effective means of promoting a sustained increase in blood flow. The information obtained on the nature of the circulatory effects of ultrasonation permits a more satisfactory evaluation of this new method of treatment.
