Solution Overview

Problem

Existing electrostimulation methods are passive and do not effectively target the peripheral nervous system, leading to muscle fatigue, reduced recovery, and inadequate rehabilitation outcomes due to mismatched sensory and proprioceptive information, and inadequate electrical stimuli that exhaust biochemical reserves and violate muscular fiber activation processes.

Innovation Solution

An electrostimulation method that generates synchronized electrical signals mimicking natural body movements, using myographic data to create programs that activate muscles at precise moments, with adaptive sensors to adjust stimulation rhythm and amplitude based on actual muscle contraction, ensuring physiological alignment with the nervous system.

AI summary

An electrostimulation method of at least one muscle group responsible for performing a complex movement includes associating to each of the muscles of the at least one muscle group an electrostimulation channel provided with at least one respective electrode. Each electrostimulation channel is suitable to transmit to the respective muscle bipolar electrical pulses in sequence. For all the electrostimulation channels, a same cycle time defining a repeatable period of stimulation is determined, in which, within the stimulation period, each channel performs its own stimulation sequence. Each stimulation period is sub-divided into two half-periods of equal duration. Each half-period is sub-divided into sub-intervals of the same duration. At least one of the sub-intervals is a stimulation sub-interval wherein a basic sequence of pulses including one or more pulse packets is performed, each pulse packet having a predetermined sequence of individual bipolar electric pulses.
