. The cerebral cortex forms excitation traces, reshaping neuromotor functions The brain gives instructions. ' Electrical stimulation contracts the musclesto complete the ' movement actions. Records the EMG signals When the threshold is reached, the electrical stimulation is triggered. Muscle activity (contraction and relaxation) A pair of electrodes collect EMG A single electrode shields interference. ETS (EMG Triggered combines voluntary contractions with neuromuscular stimulation. This combination is regarded as the best approach for muscle rehabilitation, the results are achieved faster than EMG on its own or using stimulation only.
