What are the effects of ultrasound therapy?
The effects of ultrasound therpay are still being disputed. To date, there is still very little evidence to explain how ultrasound causes a therapeutic effect in injured tissue. Nevertheless practitioners world wide continue to use this treatment modality relying on personal experience rather than scientific evidence. Below are a number of the theories by which ultrasound is proposed to cause a therapeutic effect. Thermal Effect As the ultrasound waves pass from the treatment head into the skin they cause the vibration of the surrounding tissues, particularly those that contain collagen. This increased vibration leads to the production of heat within the tissue. In most cases this cannot be felt by the patient themselves. This increase in temperature may cause an increase in the extensibility of structures such as ligaments, tendons, scar tissue and fibrous joint capsules. In addition, heating may also help to reduce pain and muscle spasm and promote the healing process. Our Ultra Soun
