Ultrasound therapy is the application of sounds over 20,000 Hz for therapeutic purposes. By its mechanical effect it results in thickening and thinning of the tissue, which represents the form of micro-massage within the tissue.
The use of ultrasound increases the local circulation of blood, reduces swelling, redness and pain caused by injuries, and reduces muscle stiffness.
Ultrasound is most commonly used for:
- Pain that occurs when bones, joints and muscles are injured
- Various skin infections
- Increased muscle tension – muscle spasm
