(b) Thermal Effects: thermal effects of ultrasound can improve the skin surface
temperature, accelerate the blood circulation, increase uptakes of nutrients of the skin cells, reduce nerve excitability play a role in analgesia, so that the spasm of the muscle fiber relaxation, play the role of antispasmodic. The internal heat is the heat of ultrasound, 79% to 82% of the heat carried away by blood from the active region,18% to 21% of the heat conduction and spread to adjacent tissues, therefore, the patient has no obvious thermal sensation.
