A physiotherapy ultrasound machine (also called a therapeutic ultrasound device) is a medical device that uses high‐frequency sound waves (typically around 1–3 MHz) to deliver energy deep into soft tissues (muscles, tendons, ligaments).
This energy can:
Promote blood flow and circulation
Reduce inflammation and pain
Increase tissue extensibility and aid healing
Help with scar tissue reduction and joint mobility
Provide deep heating effects during treatment sessions
