Ultrasonic Therapy


the use of ultrasound for therapeutic purposes; a method of physiotherapy. Using vibrations in the range of 500 to 3,000 kilohertz, ultrasonic therapy exerts a marked analgesic, spasmolytic, anti-inflammatory, and overall tonic effect. It stimulates blood and lymph circulation and regenerative processes and improves nerve-tissue nutrition.

There are portable and stationary apparatus, both operating at a frequency of about 900 kilohertz in continuous or pulsating modes, with a power of 0.1 to 1.0 watt per sq cm of area of the emitter. Ultrasound is applied to the reflexogenic zones or the diseased parts of the body over an area of 100 to 200 sq cm. A course of treatment involves ten to 12 sessions, each session lasting five to ten minutes.

Ultrasonic therapy is used to treat diseases of the peripheral nervous system, joints, and skin, gynecological disorders, and various inflammatory diseases. It is also helpful in treating the clouding of the vitreous body and cornea. It is contraindicated in persons with tumors, acute infections, and marked cardiovascular disorders.
