Ultrasonic Therapy

The most important mechanical wave used in physiotherapy is Ultrasound. Ultrasonic Therapy is the utilization of ultrasound energy to treat body tissues. Ultrasound is generated by a transducer head which consists of a crystal mounted at the front that transforms one form of energy into another.

There are a number of methods by which ultrasonic therapy is applied. The most common method is to use a “Contact” application, where a thin layer of oil or gel is applied to the skin prior to treatment. The requirement for the Coupling Medium is that it has a similar acoustic impedance to skin.

The crystal vibrates and therefore when in contact with tissue provides a form of micro massage. This enables treatment to be given to a greater depth than is possible manually and also when, at times of acute injuries, pressure cannot be exerted by hand because of tolerable pain to the patient.

When ultrasound enters the body it can exert an effect on the cells and tissues via two physical mechanisms: Thermal and Non-Thermal.

Uses

Following injury, a number of cellular and chemical events occur in soft tissues. The major cellular components of the repair process include platelets, mast cells, polymorphonuclear leucocytes (PMNLs), macrophages, T lymphocytes, fibroblasts and endothelial cells. These cells migrate as a module into the injury site in a well-defined sequence, which is controlled by numerous soluble wound factors.

These wound factors originate from a number of sources such as inflammatory cells, inflammatory cascade systems or from the products of damaged tissue breakdown.

The whole repair process, for convenience, can be divided into three phases as below:

• Inflammation

• Proliferation/granulation tissue formation

• Remodeling.
