Ultrasound Therapy
Ultrasonic waves or sound waves of a high frequency that is not audible to the human ear are produced by means of mechanical vibration in the metal treatment head of the ultrasound machine.
The treatment head is then moved over the surface of the skin in the region of the injury transmitting the energy into the tissues.
When sound waves come into contact with air it causes a dissipation of the waves, and so a special ultrasound gel is placed on the skin to ensure maximal contact between the treatment head and the surface of the skin and to provide a medium through with the sound waves can travel.
Ultrasound can also be applied under water which is also a medium for ultrasound waves to travel through.
Effects of therapeutic ultrasound
The effects of therapeutic ultrasound are still being disputed. To date, there is still very little evidence to explain
