It is disclosed an apparatus and a method for the conditioning of muscular fibrils reaction coordination capacity in consequence of an original motor exciter pulse, by means of the application on the muscle in isometric contraction, even a light contraction, of a succession of mechanic pulses, comprising means for the production of pressure pulses, means for the application of said pulses on the epidermis adjacent the muscle and means for the transmission of said pulses from said production means to said application means, wherein said application means and said means for the transmission of said pulses from said production means to said application means constitute a closed circuit inside which a compressed fluid or a substantially uncompressible fluid is present.Linvention concerne un appareil et un procédé permettant de conditionner la capacité de coordination de réactions de fibrilles musculaires suite à une impulsion dexcitation motrice originale, par lapplication sur le muscle en contraction isométrique, même en contraction légère, dune succession dimpulsions mécaniques. Lappareil selon linvention comprend un moyen de production dimpulsions de pression, un moyen dapplication de ces impulsions sur lépiderme adjacent au muscle, et un moyen de transmission de ces impulsions du moyen de production au moyen dapplication, le moyen dapplication et le moyen de transmission des impulsions du moyen de production au moyen dapplication constituant un circuit fermé contenant un fluide comprimé ou un fluide sensiblement incompressible.
