A physical therapy ultrasound device, also called therapeutic ultrasound, may be used by your physical therapist to
- Help soften your tight muscles or other tissues to improve your range of motion;
- Help increase blood flow to your injured body part to aid in faster healing; or
- Relieve your pain.
However, therapeutic ultrasound should not be used on certain body parts or on people with certain conditions. Know more about the contraindications for physical therapy ultrasound.
