Claim 10:
11. An electrostimulation apparatus to stimulate at least one muscle group responsible for performing a complex cyclic movement, comprising:
a plurality of electrostimulation channels provided with at least one respective electrode; each electrostimulation channel being adapted to transmit to a respective muscle bipolar electrical pulses in sequence;
at least one power board to generate sequences of electric pulses;
storage means in which at least one electrostimulation program is stored;
an electronic control unit to control the power boards according to an electrostimulation program stored in the storage means;
wherein:
said electrostimulation program is based on an electromyographic recording of the complex cyclic movement and is adapted to provide synchronized electrostimulation of the muscles of the at least one muscle group so as to allow reproducing the complex cyclic movement;
said electrostimulation program is given by repetition, on each electrostimulation channel, of electrostimulation periods or intervals having a same cycle time, wherein an associated stimulation sequence is defined within each stimulation period for each channel;
each stimulation period is divided into two half-periods of equal duration;
each half-period is divided into a plurality of sub-intervals of equal duration;
at least one of the sub-intervals is a stimulation sub-interval wherein a base sequence of pulses comprising one or more of pulse packets is executed;
each pulse packet is given by a predetermined sequence of individual bipolar electric pulses;
wherein each stimulation period of each channel has a half-period free of basic pulse sequences and has an other half-period with at least one stimulation sub-interval, and at least two of the stimulation periods of respective channels have different half-periods free of basic pulse sequences.
