Definitions

  • the present invention consists of a method by which a verification of the state of electrostimulation garments, such as vests or other body adaptation, is obtained, said garments being used in the so-called global EMS.
  • Electro-stimulation consists in the application of electrodes in areas of the body through which a certain electric current is passed continuously or cyclically, normally adjustable in intensity, so that this current produces in the muscles to which more or more contractions are applied less intense depending on the intensity that is passed through said electrodes.
  • the global EMS acts on 10 or more muscle groups, where more than 300 muscles are stimulated simultaneously, these electrodes are designed by the manufacturer with different shapes and sizes, these being of great importance for the correct distribution of the current to Apply. It is common use that the electrodes are arranged on the inside of garments specifically designed for use, so that the location of said electrodes is made to coincide, after wetting, with the area of the skin suitable for the stimulation of certain muscles.
  • the garments or electrodes are provided with a connector and wiring to connect to the generator of the impulses of the electric current.
  • the current density per unit area will depend on the state of the electrode. If, for example, half of an electrode has no contact because the conductive filaments have broken, the current density in the other half of the electrode will be double generating an uncontrolled muscle stimulus.
  • the electrodes are in optimal condition, and the entire surface of said electrodes is conductive, transmitting the current to the skin, and to the corresponding muscle.
  • the electrodes deteriorate over time, the conductive surface being modified, and therefore the current density and the expected muscle contraction with respect to a certain intensity.
  • the programmed setpoint intensity, intended for a certain current density at each electrode does not vary, because the corresponding control unit "does not know" that there is a deterioration.
  • the current density increases locally, even very significantly, so that the area to be electrostimulated has a different surface, with a different current density, and with a different muscle contraction than desired.
  • This error can occur, as for the point of application, and can occur as a difference between two symmetric twin electrodes: left and right part in the same garment, so that if one of them has partially deteriorated conductive tissue and the symmetric acting it will correctly produce burns at best, but at worst, a need to raise the setpoint intensity to reach the intended stimulus levels.
  • electromusculation electrodes have their performance in two parts of the muscle, usually at the motor point and in the belly of the muscle, hence the shape and size that the manufacturer uses in the design of each electrode.
  • a poor distribution of the active conductive mesh results in a lack of control over the impulse with the aforementioned consequences, since overstimulation arises when the intensity must be raised to generate muscle contraction through the conductivity of the added moisture, and in the symmetric part this need does not occur, generating a greater contraction and, consequently, a decompensation in muscular work which would increase the CPK levels released by the electrode stimulated muscle that worked properly.
  • the present invention consists of a method for checking the correct operation of electrodes in electrostimulation garments, designed to solve the problem described, this part not knowing any known method for capturing by means of a test the correct state of operation of electrostimulation electrodes, beyond mere manual checking (by resting your hand on the electrode to feel the electrical impulse).
