How Does Ultrasound Therapy Work?

Ultrasound Therapy:


Ultrasound; sound waves vibrating at frequencies over those that the human ear can hear, more prominent than 20,000cycles each second (hertz, Hz).

Helpful ultrasound is what is utilized for remedial (rather than symptomatic) purposes and is generally delivered at 1 million cycles each second or 1 megacycle (MHz). For the most part US recurrence is somewhere in the range of 0.7 and 3.3 MHz.


Ultrasound was first explored in Europe and was acquainted with the United States in the mid 1950’s, since this time, the utilization of ultrasound has developed, and it stays an extremely well known methodology today.

System of activity

US is delivered by a high-recurrence exchanging current being applied to a precious stone made of quartz or a manufactured (for example barium titanate or lead zirconate). The current makes the precious stone curve, first in one bearing and afterward the other, as the current substitutes. This twisting of the gem makes what is called piezoelectric energy. The vibration energy is moved to a metal plate, ordinarily nickel-plated metal, and afterward the patient’s tissue. The precious stone and metal plate are housed cavitation machine in the transducer or sound top of the unit.

Actual properties

It isn’t sent through a vacuum

It is sent inadequately through gases

It is sent best through without gas fluids and high-thickness solids

The control center

Like a radio transmitter.

Has an oscillator that produces electromagnetic wave at high frequencies.

Transducer head

Converts electromagnetic waves into sound waves.

Bigger transducer surface is better (7-13cm*), however adequately little to keep in touch.

Waves are produced in a round and hollow pillar opposite to ne’er do well surface. Hence hold the transducer head corresponding to tissue surface.

Never permit the pillar to shoot straight into the air without gel or water as this might harm the precious stone.

To test precious stone: water on the head, turn up the power the water should stream.

Coupling specialists

Air doesn’t lead well, should utilize a coupling medium. Utilize a business gels, not mineral oil and a few gels will contain substances that can advance recuperating, for example, vit E, aloe.


As US goes through human tissue, it continuously diminishes in power because of constriction. Constriction is the aftereffect of ingestion, reflection and refraction, with retention representing about portion of lessening.
