Description :
Electro-musculation is the action which makes it possible to generate a contraction of muscle fibres. A natural contraction of the driving muscles is caused by pulses coming from the central nervous system. Electro-musculation causes a muscular contraction obtained by pulses coming from outside (of the power generators) starting from electrodes placed in contact with the skin, on the muscle to be contracted. One distinguishes: - The isometric contraction, which is carried out without movement and length modification of a muscular segment. - The isotonic contraction, which is accompanied by a shortening of the muscle.
