This is the use of electro physical agents to aid and speed up the healing process. The main electrotherapy modalities used at active physiotherapy are ultrasound and interferential therapy.
Ultrasound is a form of mechanical vibration that at increasing frequencies is known as sound energy. Sound energy that is above the human level of hearing (approx. 14Hz) is termed Ultrasound. At different frequencies this ultrasound energy can be used for many different things i.e. ultrasound imaging. The frequencies used in therapy are typically between 1.0 and 3.0 MHz (1MHz = 1 million cycles per second). At Active Physiotherapy we mainly use this treatment for soft-tissue injuries to muscles, tendons and ligaments.
Ultrasound uses ultrasound waves to assist and speed up healing throughout all stages of the healing process. In the initial inflammatory stage, the ultrasound has a stimulatory effect on the “healing cells” present during this stage (Primarily white blood cells). In the later stages of tissue healing, it is shown to increase the tissues tensile strength and enhance its mobility.
Interferential therapy uses electrical current to provide pain relief by stimulation of peripheral never fibres or muscle stimulation of muscle fibres. At Active Physiotherapy, this is mainly used for muscle stimulation when attempting to re-educate a muscle following injury.
