Therapeutic Ultrasound is a treatment method that uses sound waves to treat pain, inflammation and muscle spasms by stimulating the body with high-frequency micro vibrations.
How does it work?
Therapeutic ultrasound in physical therapy is a relatively low intensity technique that uses high-frequency sound waves (ultrasound) to speed healing in injured joint or muscle tissue. The frequency used is typically 1 to 3 MHz. At this frequency, the waves tend to travel through tissue with high water or low protein content, and to bounce off cartilage and bone. They are absorbed primarily by connective tissue: ligaments, tendons, and fascia.
Therapeutic ultrasound has two primary types of benefit: Thermal effects involve energy absorbed from the sound waves heating the tissue. When tissue is heated to 40 to 45 °C (104 to 113 °F), it can enter a state of hyperaemia (increased blood flow), which speeds healing and reduces chronic inflammation.
