Key result
Ultrasonic irradiation of the extremities fails to promote a sustained increase in blood flow.
Why the study?
Does ultrasonic irradiation increase blood flow and temperature in human skeletal muscle?
Does ultrasonic irradiation increase blood flow and temperature in human skeletal muscle?
Ultrasonic irradiation does not produce a sustained increase in blood flow in human skeletal muscle.
Ultrasonic irradiation lacks support for sustained blood flow increases; leaves open acute or alternative vascular applications.
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.

BICKFORD et al. (1953) studied this question. Ultrasonic irradiation was evaluated on Volumetric blood flow changes and temperature measurements. Ultrasonic irradiation of the extremities was not found to be an effective means of promoting a sustained increase in blood flow.
