A method of monitoring or assessing the motion of the limbs of a body when performing repetitive cyclic activity uses inertial measurement units secured to each of the limbs to be monitored. The operation of all of the IMUs is synchronised by way of a pulse from a computer. On performing the repetitive cyclic activity such as walking, running, trotting or galloping, the outputs of the IMUs are assembled and analysed in realtime, to determine the relative phase of the limb movements, from which an assessment of the gait may be made.

L'invention concerne un procédé de surveillance ou d'évaluation du mouvement des membres d'un corps dans l'exercice d'une activité cyclique répétitive, procédé qui utilise des unités de mesure inertielle (UMI) fixées sur chacun des membres à surveiller. Le fonctionnement de l'ensemble des UMI est synchronisé par le biais d'une impulsion provenant d'un ordinateur. Lors de l'exécution d'une activité cyclique répétitive comme la marche, la course, le trot ou le galop, on regroupe et on analyse en temps réel les sorties des UMI afin de déterminer la phase relative des mouvements des membres, point à partir duquel il est possible d'effectuer une évaluation de l'allure.
