The electro muscle stimulator is an appliance able to generate specific electrical currents that cause muscle contraction by substituting the impulses generated by the central nervous system.

In this case, the current is applied at the point where the nerve ends come into contact with the muscle cells (neuromuscular plate).

By modulating a series of variable parameters like the frequency of electrical impulses, duration of contraction and recovery, etc....various programs can be obtained useful for achieving different goals, strengthening muscle power, toning up beauty treatment, right up to the decontraction of injured and contracted muscles.
Besides the correct positioning of the electrodes (see attached table), care must also be given to choosing the right program for the result to be achieved. On this in fact will depend to a great extent the success of training through induced electric stimulation.
