Ultrasounds are mechanical waves with a frequency higher than that which humans can hear (about 20,000 Hz). When applied to biological tissue, they can cause significant changes in cells and tissues, increasing temperature and creating micro-vibrations.


In physical therapy, ultrasounds have been used since the 1940s. They operate at therapeutic frequencies of 1 to 3MHz and have 2 to 5cm ultrasonic wave emitting heads. They enter the body through the surface of the skin, which they penetrate.

They are indicated for the treatment and treatment of many diseases, such as arthritis, chronic polyarthritis, brachial pains, sprains, ligament injuries - sprains, epicondylitis, periarthritis, myalgias and neuralgias, cervical syndrome, backaches, sciatica and tendon inflammations.


Ultrasounds have helped physical therapy in the resolution of many pathological neurological but mainly orthopedic conditions. They are an extremely effective technique with a beneficial effect, since they cause muscle relaxation and analgesia, improve the circulation of oxygen inside the muscle, increase metabolism and muscle nutrition, dissolve adhesions and muscle spasms, heal cells, improve the mobility of the joints, healing of fractures, increasing the elasticity of soft tissues and better absorption of drugs.

Ultrasounds without a thermal effect are used to reduce swelling caused by inflammation, muscle injuries, fractures and after operations (eg arthroscopy or arthroplasty).
