Abstract

Muscle blood flow was measured using a radioactive tracer technique in five normal subjects. Flow values obtained during application of 2450 MHz microwave therapy were compared with resting values and in each case the treatment produced a significant increase; the mean values being 2.9 ml/100g/min at rest and 11.4 ml/100g/min during application of the microwave therapy. Comparison is made with previous studies using other therapeutic agents and it is concluded that the most significant effect on muscle blood flow is produced by microwave therapy.
