What is ultrasound therapy

Ultrasound therapy uses sounds of a high frequency and intensity that are converted to mechanical and heat energy. The treatment is administered by placing the application head of the device in continuous or pulse application onto the skin, which has been given a coating of conductive gel. The depth of impact varies between 2-6 cm. The site, mode, length and frequency of application must be prescribed by a doctor. The treatment procedure may be delivered by a physiotherapist or a trained electrotherapy assistant and usually lasts up to 12 minutes.

How ultrasound therapy helps

About one third of the ultrasound energy is absorbed in the molecules and results in a type of micro-massage in the targeted tissues, warming them up. This brings about muscle relaxation as well as improved blood circulation and tissue metabolism. Subsequently, pain, stiffness and swelling are reduced. The ultrasound waves further enhance certain chemical reactions in the connective tissues that lead to the better healing of bruises and the softening of stiff tissues.
