Ultrasound is a form of physiotherapy treatment that involves using sound waves to produce vibrations in targeted soft tissues. This effect is capable of increasing blood flow, decreasing scar tissue and reducing swelling. Ultrasound can be used to treat both acute and chronic injury types. It is particular effective at treating different forms of tendinitis (used often with rotator cuff strains) and muscle tearing. When used in combination with manual treatment and exercise, ultrasound can result in faster soft tissue healing times.
