Thermal ultrasound therapy uses a continuous transmission of sound waves through a wand placed directly on the skin. The sound waves, which we cannot hear, cause microscopic vibrations to create heat and friction in the affected areas. This creates a warming effect, which encourages blood flow.
The warming effect helps to reduce swelling and chronic inflammation, and promotes healing in the soft tissues by increasing the metabolism of the tissue cells. Therapeutic ultrasound treatments are particularly helpful with muscle and joint pain.
