Ultrasound also known as ultrasound imaging or scanning, exposing parts of the body with high-frequency sound waves to produce images of the body interior. Ultrasound pictures are taken in real time (real time) can immediately show the structure and movement of muscles and tendons, as well as how blood flows through the blood vessels. Ultrasound is a medical examination without intervention that helps physiotherapists to assess and treat muscle disorders on the basis of a more accurate diagnosis.

What are the benefits and advantages of ultrasound compared with other surveys:
• Ultrasound is non-invasive (no needles or injections) and is usually painless.
• Ultrasound is widely available to use and less expensive than other imaging methods.
• Ultrasound does not use ionising radiation.
• Ultrasound provides a clear picture of soft tissues. Traditional X-rays can only give a clear picture of the hard tissue ie bone.
• Ultrasound makes it possible to scan the patient in the dynamic tests and movements. Compared with MRI in which the patient must lie very still for several minutes.
• Ultrasound provides real-time imaging.
• In contrast to the strong magnetic fields in magnetic resonance MR affects ultrasound not e. pacemakers, ferromagnetic implants or fragments within the body.
• Ultrasound is also an excellent alternative to MRI as a claustrophobic patient may experience as difficult.

Risks: There are no known harmful effects on muscle / skeleton by ultrasound on humans.
