The aim of this paper was to study the possibility to diminish the reposition error, always present when the EMG Surface Electrodes are  removed and re-inserted in the same or in a different session.  We have obtained a lesser than 2% relative error, with a protocol of our own development,  which took account: a) The distance between electrodes, b) the pressure on the electrodes, c)  position on skin,  d) apply muscle force and e) the subject posture.  The trials were performed within twenty days of difference, in five healthy people .
