Patent number: 11607166Abstract: A method for quantifying the balance of an individual recording, on a memory, at least one statokinesigram of the individual obtained from a platform comprising pressure and/or force sensors; extracting, by a processor and from the at least one statokinesigram of the individual recorded on the memory, values of at least one position trajectory parameter of the pressure center and values of at least one stability trajectory parameter of the pressure center; determining, by the processor, the value of a plurality of quantifiers, from the values of the trajectory parameters extracted; comparing, by the processor, said values of the plurality of quantifiers with the values of the same quantifiers obtained from reference statokinesigrams; and determining, by the processor, said value representative of the balance of the individual at the end of the comparison.Type: GrantFiled: November 9, 2017Date of Patent: March 21, 2023Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ECOLE NORMALE SUPERIEURE PARIS-SACLAY, UNIVERSITE PARIS DESCARTES, ETAT FRANCAIS—MINISTERE DE LA DEFENSE—DIRECTION CENTRALE DU SERVICE DE SANTE DES ARMEESInventors: Nicolas Vayatis, Pierre Paul Vidal, Nikolaos Promponas Kefalas, Julien Audiffren, Alain Yelnik, Catherine De Waele Vidal, Damien Ricard

Publication number: 20220338759Abstract: The present invention presents a device for calculating, during one step or each successive step of the gait of a subject, the push-off P0 of the subject, which is the power per kilogram released by the ankle push-off moment, which comprises: at least one inertial measurement unit (1A, 1B) on one foot of the subject, the inertial measurement unit (1A, 1B) having: at least one accelerometer to measure the vertical and antero-posterior accelerations and/or at least one gyroscope to measure the medic-lateral angular speed data {acute over (?)} during the gait, storage and calculation means (2A) connected to the Inertial measurement unit (1A, 1B), configured to calculate: for the foot, and for the step or each successive step of the gait:—the time of the heel-off and the time of the toe-off,—the push-off P0, by the Euler's equation stating that the sum of moments acting on the foot taken as a rigid body, being equal to the rate of change of the angular momentum of the foot, with the calculation of the push-off P0Type: ApplicationFiled: April 23, 2020Publication date: October 27, 2022Inventors: Pierre Paul VIDAL, Aliénor VIENNE-JUMEAU, Damien RICARD, Laurent OUDRE, Nicolas VAYATIS, Albane MOREAU, Flavien QUIJOUX

Patent number: 11246525Abstract: A method for quantifying the balance of an individual includes segmenting, as a function of time, a statokinesigram(s) of an individual so as to generate several statokinesigram portions; extracting, from the statokinesigram portions, values of at least one trajectory parameter; determining the value of at least two quantifiers, from the values of trajectory parameters extracted in the extraction step, for each of the statokinesigram portions generated in the segmentation step; and determining said value representative of the balance of the individual from the values of the quantifiers of each of the statokinesigram portions. The method may be implemented by a processor and memory.Type: GrantFiled: November 16, 2018Date of Patent: February 15, 2022Assignees: ASSISTANCE PUBLIQUE-HOPITAUX DE PARIS, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ETAT FRANCAIS—MINISTERE DE LA DEFENSE—DIRECTION CENTRALE DU SERVICE DE SANTE DES ARMEES, ECOLE NORMALE SUPERIEURE PARIS-SACLAY, UNIV PARIS XIII PARIS-NORD VILLETANEUSE, UNIVERSITE DE PARISInventors: Nicolas Vayatis, Pierre Paul Vidal, Julien Audiffren, Alain Yelnik, Damien Ricard, Ioannis Bargiotas, Laurent Oudre, Stéphane Buffat
