Tecar therapy: how it works
The physical principle on which diathermy is based is that of the capacitor.
The capacitor consists of two conductive armatures separated by an insulator and connected to an
electric generator that creates a potential difference between the two plates.
This causes electrical charges to attract and repel each other concentrating near the two elements ,
increasing the density of positive charge in one plate and negative charge in the other.
In the case of a diathermy device, the armatures are represented by the handpiece (capacitive or
resistive) and the return plate, while high-strength body tissue constitutes the insulation.
The current generator works in the long-wave radio frequency range and with a variable power in W.
In this way, there is no emission of external energy, but only a development of endogenous or
internal energy at the level of the biological tissue, produced by the movement of ions and
electrolytes, induced by the forces of attraction and repulsion generated between the two
capacitor plates.
The ability to generate a current flow through an insulator, and to exploit tissues as focal
elements of the therapeutic effect, is a differentiating feature of tecar therapy when
compared with other techniques. Diathermy, in fact, is also extremely effective in depth,
where other exogenous instrumental physical therapies lose their effectiveness.
