“Mechanical vibration at increasing frequencies is known as sound energy. The normal human sound range is from 16Hz to something approaching 15-20,000 Hz (in children and young adults). Beyond this upper limit, the mechanical vibration is known as ULTRASOUND. The frequencies used in therapy are typically between 1.0 and 3.0 MHz (1MHz = 1 million cycles per second).”

The process of healing from an injury, regardless of the tissue affected, involves a series of complicated steps within the body’s tissues. It is believed that the mechanical vibrations from the ultrasond machine can enhance the body’s ability to heal the tissues more efficiently.
Does ultrasond hurt? Can you feel it?
The frequencies used in ultrasound are so high, that you should not feel the machine working at all. The physiotherapist will apply a cool gel to the affected area, but this gel is purely to help with transmission of the soundwaves through the surface of the skin. Basically it helps to get the treatment to the area where it is needed. If you feel discomfort at any point, please inform your physiotherapist.
Is it safe?
Yes, it is safe when recommended following a thorough verbal and physical assessment by your physiotherapist. There are some conditions and situations where ultrasound may not be appopriate. During assessment your physiotherapist is ensuring that any treatment offered is safe for your condition, taking into consideration all other aspects of your general health.
How many sessions do I have?
This very much depends on your condition and individual needs. This will be discussed with you at your physiotherapy session.
Will I have to get undressed?
The Physiotherapist will need to see the skin of the area to be treated. If you agree to having ultrasound treatment, you should bring clothing that will make examination and treatment of the area more comfortable for you.
