Pulsed Signal Therapy is an innovative technological advance that uses a high-tech, non-invasive medical device to treat arthritis, accident, work, sports and repetitive stress injuries.

The PST device creates a low-power electromagnetic field through which a pulsed signal is directed to the affected area, stimulating the healing process.

The development of Pulsed Signal Therapy (PST™) technology began four decades ago following proof that certain pulsed electromagnetic fields could promote the healing of bone fractures that had failed to unite after a year or more as well as anecdotal reports that similar approaches could relieve pain and improve mobility in patients suffering from osteoarthritis and traumatic joint damage. Since existing PEMF devices had varied characteristics, an effort was made to determine whether a pulsed electromagnetic field with specific parameters that mimicked physiologic reparative activities might provide superior results. The normal stimulus for cartilage production and bone formation results from piezoelectric signals that generate a "streaming potential" in the extracellular matrix when skeletal structures are subjected to physical pressure.

Pulsed Signal Therapy (PST™) is based on the application of a very specific type of pulsed electromagnetic field to bone and adjacent tissues. The PST™ device generates a pure magnetic field output signal that employs direct current with unidirectional biological frequencies below 30 Hz. The “waveform” is quasi-rectangular with measured field strengths generally below 2 mT or 20 Gauss. The system is controlled through a pulsed unidirectional magnetic DC field with multiple output frequencies implemented via a free-wheeling diode to optimize the inductance characteristics. Various frequency/amplitude combinations are switched over automatically and are transmitted under continuous control during the treatment period. Induction of treatment takes place during the first 10 minutes at half strength followed by a combination of pulsed signals that deliver the therapy at full strength over the remaining 50 minutes.
