Ultrasound is applied directly on the skin of the patient using a wand that is round headed. You need to apply ultrasound gel on the surface where the physical therapy has to be done in order to reduce the friction on the skin due to ultrasonic waves. Generally, the frequency of the therapeutic ultrasound in physical therapy is in the range of around 0.8-1.0 MHz. The ultrasonic waves are generated due to the piezoelectric effect caused by the crystals which vibrate in the head of the ultrasound wand.

Ultrasound in physical therapy is brought about by a set of sound-waves which are produced in the ultrasound wand. These sound waves are then passed to the affected area through your skin causing vibration to the tissues. These vibrations produce heat to the effected area but the patient may not feel the heat. Apart from the likely heating effect that is produced by the ultrasound, there are some other known effects as well. The use of ultrasound in physical therapy helps in the relaxation of the tissues. They break down the tissues on the scar and generate blood flow to areas where it was previously blocked.

Ultrasound in physical therapy helps in reducing chronic inflammation and swelling by increasing the flow of blood in the affected area. According to some latest studies, it has been found that ultrasound helps in healing the fractured bone. The power density or the intensity of the ultrasound is adjustable. You can use the power density of the ultrasound as per the requirement for the healing purpose. If you need to break down the scar tissues, you’ll need a greater power density.

Phonophoresis can also be achieved using the ultrasound. The term Phonophoresis means using ultrasound to deliver the medicine into the body through the skin. The medicine is placed under the ultrasound gel are forced to go below the skin by the ultrasound waves. This kind of medication is unique and can be applied to patients who feel uneasiness with injections. Generally, it takes three minutes to five minutes for a technical ultrasound treatment. However, in the cases where the breakdown of scar tissues is treated then it may take more time. During the treatment, the ultrasound wand has to be in a constant motion depending on the comfort level of the patient.

If the ultrasound wand is placed in one place for more than few seconds, the sound energy will build up and this will make the patient uncomfortable. Some of the major conditions which can be treated using ultrasound include the muscles spasm, Peyronie’s Disease, scar tissues break down, tendonitis, non-acute joint swelling and many other treatments. However, ultrasound treatment is not permissible to treatments such as vascular abnormalities, metal implants below the treatment area and local acute infections. Also it cannot be applied on the pregnant woman’s abdomen directly. It is also not permissible to apply it on the skull, testis, eyes and the spinal cord area.
