  • the medical practitioner repeats inserting, measuring the second sympathovagal balance, and determining the reversal outcome until the reversal outcome is positive or until a certain predetermined number of portions of skin are tested or time has elapsed.
  • the electrotherapy treatment may require more than one stimulation point on the patient's ear. For example, one point may be stimulated to address lower back pain and another point may be stimulated for general pain relief. Accordingly, when the reversal outcome at step 445 is positive, the medical practitioner determines 455 a number of inserted electrotherapy needles. The testing is finished 460 when the number of inserted
  • electrotherapy needles is equal to a predetermined number of electrotherapy needles required for the electrotherapy treatment, e.g. three stimulation needles - one needle located for a specific symptom and two needles located at two different locations for general pain relief.
  • a number of inserted electrotherapy needles is less than the predetermined number of electrotherapy needles, the medical practitioner repeats choosing the location, applying the electrotherapy signal, measuring the first sympathovagal balance, determining the response outcome, inserting the needle, measuring the second sympathovagal balance, and determining the reversal outcome.

Abstract

La présente invention concerne un procédé de test électrique qui comprend la fourniture d'une batterie, et la génération d'un signal périodique dans le temps à partir d'un circuit. Le procédé de test électrique comprend en outre la fourniture d'une pointe électro-conductrice conçue pour entrer en contact électrique avec une première partie d'une surface, sans la perforer, lorsque la surface est testée, et le couplage du signal périodique à la pointe électro-conductrice.
