PSTSignals for Motion
The Regeneration Process
The effect of PST is based on the triggering of the body’s own regeneration through the physiological stimulus of signals transmitted by a magnetic field. PST forces a migration of positively charged hydrogen ions (H+) in the negatively charged extra cellular matrix.
The flow of charged particles, the hydrogen protons, affects the reconstruction of the electrical field (streaming potential) normally present around a joint and which is not only disturbed in arthritic patients, in tendonitis and injuries, but in nearly all orthopedic conditions.
The regeneration process
Pulsed Signal Therapy (PST) is based on a patent developed by an American doctor and a biophysicist of German origin, Richard Markoll. This is a therapeutic method which differs from the so-called magnetic field therapy used for many years for slowly consolidating fractures.
PST, while it can be used in bone tissue also, finds its main indication in the treatment of cartilage and of soft and connective tissues. To understand the effect of PST, it must be remembered that when a joint is subjected to compressive stress, there is a displacement of the water present in the matrix accompanied by sodium ions, leaving the negative charges of proteoglycan molecules unneutralised. By a mechanism of mechanical-electrical transduction, the mechanical stimulus is transformed into a weak electric current (potential streaming) which is thought to represent the main signal for the cartilage cells to increase the synthesis of proteoglycans and collagen.
Bone and cartilage tissues have electromagnetic natural bio-potentials which are of crucial importance to the formation and the dynamic functional adaptation of the tissue. Various factors, including electric stimuli such as pulsed electromagnetic fields, can activate the regeneration process. The combined energy parameters of Pulsed Signal Therapy (PST) belong to the range also observed in the connective tissue.
Supported by clinical studies and laboratory research
- Early improvement of the joint function (mobility and flexibility) by the removal of muscular tension, with normalized joint kinematics and reduced pain
- Acceleration of the healing process in injuries to joint-related structures
- Stimulation of the chondrocyte activity on streaming potentials with regeneration of the cartilage tissue
- Stimulation of the osteoblast activity through piezoelectric potentials with stabilisation of the bone thickness
If the potential streaming is the signal for chondrocytes to produce new matrix, the same effect can be obtained by exposing the joint to an electro-magnetic field, producing currents which stimulate those of the organism. Administration in this way of a low strength pulsed signals at a frequency similar to the biological one that is capable of creating an electrical field in the joint, prompting the regeneration of the cartilaginous tissue, and thus conferring physical chondroprotection.
PST has a specific signal pattern:
- Constant changes in intensity, duration and frequency (frequency 1-30 Hz, field strength 0.5-1.5 mT, 5-15 Gauss)
- The signal corresponds with the natural physiological body signals
- The signal activates the self healing process of the body
