What is Therapeutic Ultrasound?
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.
Used by doctors, chiropractors and physical therapists since the 1940s, Sonic Relief makes it possible to enjoy the same benefits of clinical therapeutic ultrasound safely in the comfort and convenience of your own home.
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.
Non-thermal effects result from the vibration of the tissue causing microscopic air bubbles to form, which transmit the vibrations in a way that directly stimulates cell membranes. This physical stimulation enhances the cell-repair effects of the inflammatory response.
In addition, ultrasound has also been shown to facilitate the healing of wounds and bone fractures.
About Ultrasound Waves
Adds Heat: Ultrasound waves penetrate the skin’s surface causing soft tissues to vibrate creating gentle heat.
Increases Blood Flow: Ultrasound waves cause increases in tissue relaxation and local
blood flow to the treatment area. The effect of the increase in local
blood flow can be used to help reduce local swelling and chronic
inflammation. Increased blood flow delivers needed oxygen and
nutrients, and removes cell wastes.
Enhances Absorption of Analgesics and Anti-inflammatory Agents:
Ultrasound can also be used to achieve phonophoresis. This is a
non-invasive way of enhancing the absorption of analgesics and
anti-inflammatory agents to tissues below the skin using ultrasound
Decreases Trigger Point Pain: Ultrasound works by decreasing
the pain/sensitivity associated with muscular trigger points. Studies
have demonstrated trigger points to be important causes of headache,
back ache and all types of muscular/soft tissue "overuse" syndromes.
