Ultrasound is a therapeutic treatment method utilizing sound waves to treat pain, inflammation and muscle spasm. Therapeutic Ultrasound is a method of stimulating tissue beneath the skin’s surface using sound waves. This high frequency massage has sound waves typically between 800,000Hz and 2,000,000Hz. The sound cannot be heard by humans.
Ultrasound waves are applied to tissues using a round-headed wand or transducer. Ultrasound gel is used on the skin in order to reduce friction and act as a conductor of the ultrasonic waves. The ultrasonic waves that pass through the skin cause a vibration of the local tissues. This vibration or cavitation can cause a deep heating locally though usually no sensation of heat will be felt by the patient.
Sound waves are pulsed at the area causing your pain at millions of times per second. These waves stimulate your joints, ligaments, tendons, muscles and other tissues providing targeted pain relief without drugs or surgery. Ultrasound waves do the following:
Add Heat: The sound waves penetrate the skin and surface layers and cause the soft tissue to vibrate, producing gentle healing vibrations within the affected area that soothe inflammation and relieve pain.
Increase Blood Flow: Ultrasound waves also cause tissues to relax and increase blood flow to help reduce local swelling and chronic inflammation. Increased blood flow also delivers more oxygen and nutrients to the tissue, removes cell waste and aids healing.
Decreases Trigger Point Pain: Ultrasound works by decreasing the pain and sensitivity associated with muscular trigger points. Studies have demonstrated trigger points to be important causes of headache, back ache and all types of muscular and soft tissue “overuse” syndromes.
Ultrasound therapy has been shown to cause increases in tissue relaxation, local blood flow, and scar tissue and adhesion breakdown. The effect of the increase in local blood flow can be used to help reduce local swelling and chronic inflammation, and, according to some studies, promote bone fracture healing. Ultrasound enhances the body’s natural healing process and can reduce irritation to nerve roots.
