The invention concerns a system for controlling a cyclic motion of at least one body segment of an individual, comprising: -at least one three-dimensional motion sensor (2), -a means for attaching said sensor to said body segment of the individual, said system being characterised in that it further comprises: -a processor (5) coupled to said sensor (2) and capable of being carried by the individual, in which a reference cyclic motion and tolerance limits specific to the individual concerning at least one parameter of the motion to be controlled, which change depending on the progress thereof, are stored, said processor being configured to detect said cyclic motion, integrate the measurement data from said sensor in such a way as to calculate said parameter(s) of the motion of said segment and to compare, in real time, the parameter(s) of the measured motion (Ctr) with the parameter(s) of the previously recorded reference motion (Cref) of the individual, -a feedback device (4) coupled to said processor (5), designed to provide the individual with real-time information on the compliance of the parameters(s) of the measured motion with respect to the parameter(s) of said reference motion.Linvention concerne un système de contrôle dun mouvement cyclique dau moins un segment corporel dun individu, comprenant: -au moins un capteur (2) tridimensionnel de mouvement, -un moyen de fixation dudit capteur sur ledit segment corporel de lindividu, ledit système étant caractérisé en ce quil comprend en outre: -un processeur (5) couplé audit capteur (2) et apte à être embarqué sur lindividu, dans lequel un mouvement cyclique de référence et des bornes de tolérance propres à lindividu sur au moins un paramètre du mouvement à contrôler et évolutives en fonction de sa progression sont enregistrés, ledit processeur étant configuré pour détecter ledit mouvement cyclique, intégrer les données de mesure dudit capteur de sorte à calculer le(s)dit(s) paramètre(s) du mouvement dudit segment
