PULSED SIGNAL THERAPY

The basis for the Pulsed Signal Therapy (PST) system is a unique pulsed electrical signal that stimulates connective tissue growth and repair. In healthy individuals, connective tissue cells respond to mechanical stress by producing more tissue components. The mechanism by which these cells become aware of mechanical stress and are thus stimulated to grow is thought to be a mechanical-electrical transduction generated by fluid movement in the cartilage. This fluid movement causes charged ions and molecules in the extracellular fluid to be realigned and flow past tissue components that are stationary and carry electric charges. This phenomenon, called streaming potentials, is impaired in cases of osteoarthritis and trauma related joint disorders. Because of altered tissue structure and, of course, the pain associated with mechanical stress, the mechanical-electrical transduction does not take place and thus the connective tissue does not receive the appropriate stimuli. Repair of the tissues is thus further slowed down resulting in the typically slow and painful recovery involved in orthopedic and sports injuries.
