Electricity in Pain treatment
The therapeutic use of electricity in pain control started to become wildly known in the 2nd half of the 20th century. The TENS (transcutaneouselectric nerve stimulation) technology is a non-invasive therapeutic method inhibiting the signal transfer of pain sensory neurons, having milliamp strong impulses of DC, thus decreasing pain sensation. This method provides sufficient results in pain management, but it often involves side-effects, and in many cases it cannot be used due to current intensity.
MTC (micro-current therapy) is a further development of the above method also referred to as MENS (microelectic nerve stimulation). This method uses a current of some 100µA volume instead of mA-s, thus the MTC method is much safer than the TENS method, and the intensity of the electric current is below the sensory threshold of the human body.
This definition refers to the electric voltage of the cells, e.g. the difference in electric potential between the inner and outer side of the cell membrane, as well as the electricity produced by tissues or organs themselves. The electric voltage of the cells has several important tasks: it plays an important part in cell metabolism, supports the communication between cells and varios other processes of the cell function.
Mode of Action
The mode of action is based on the effect exerted on the cell's action potential and on its current flow level detailed above. Areas injured or affected by a disease have higher resistance than their environment. TENS impulses – as opposed to the former opinion “the more is better” – are too high, can not intervene successfully into the fine mechanisms and patterns of the nervous system. The micro-current method, however, is able to penetrate into these areas, imposing influence on the electricity of the organisms themselves, and inducing and maintaining electric reactions that promote the regeneration processes.
The beneficial effect of the exogenous micro- current is in the fact that it regenerates the electrical imbalance of the injured cells, and this affects their physiological status, plus decreases the electrical resistance of the affected areas. In this way endogenous currents are able to penetrate into deep layers and accelerate tissue regeneration plus maintain tissue homeostasis.
