Abstract

L'invention concerne un dispositif (10) de diagnostic pouvant mesurer la capacité électrostatique d'un site de mesure d'une personne examinée uniquement par mesure d'un courant de transition à l'aide d'électrodes correspondantes (12, 13) afin de diagnostiquer un site anormal dans un système neuro-musculo-squelettique. Ce dispositif permet à quiconque de procéder à un diagnostic simplement, sans nécessiter de connaissances ou de compétences professionnelles complexes, et l'utilisation de la capacité électrostatique d'une personne examinée permet au diagnostic d'être moins affecté par la transpiration qu'un diagnostic classique basé sur la résistance électrique, améliorant ainsi la fiabilité des résultats du diagnostic.
