A system for controlling a cyclic movement of at least one body segment of an individual, comprising: - at least one three-dimensional movement sensor; - a means for fastening said sensor to said body segment of the individual; - a feedback device; and - a processor which is coupled to said sensor and is capable of being carried on the individual, said processor being configured to record a reference cyclic movement specific to the individual and minimum and maximum tolerance limits for a parameter of the movement to be monitored, the tolerance limits being specific to the individual and changing depending on their progress, the tolerance limits of the movement parameter being dynamic limits so as to define a curve of minimum values and a curve of maximum values surrounding the curve followed by the movement parameter of the reference cyclic movement; detect, by means of the sensor, said cyclic movement of the body segment; from a plurality of cycles of the detected cyclic movement, calculate the average duration of a cycle and calibrate the reference cyclic movement with said average duration; from measurement data of said sensor, calculate said parameter for the detected movement; compare, in real time, by means of a signal point-to-point comparison algorithm, said parameter for the detected movement (Ctr) with said parameter of the reference cyclic movement (C ref) calibrated to determine whether the result of the comparison is between the tolerance limits; and trigger feedback via the feedback device when said parameter for the detected movement goes outside the margin of error defined by the tolerance limits; - the feedback device being coupled to said processor and being suitable for providing the individual with real-time information on the compliance of the parameter of the detected movement with respect to the parameter of said reference cyclic movement. - at least one three-dimensional movement sensor; - a means for fastening said sensor to said body segment of the individual; - a feedback device; and - a processor which is coupled to said sensor and is capable of being carried on the individual, said processor being configured to record a reference cyclic movement specific to the individual and minimum and maximum tolerance limits for a parameter of the movement to be monitored, the tolerance limits being specific to the individual and changing depending on their progress, the tolerance limits of the movement parameter being dynamic limits so as to define a curve of minimum values and a curve of maximum values surrounding the curve followed by the movement parameter of the reference cyclic movement; detect, by means of the sensor, said cyclic movement of the body segment; from a plurality of cycles of the detected cyclic movement, calculate the average duration of a cycle and calibrate the reference cyclic movement with said average duration; from measurement data of said sensor, calculate said parameter for the detected movement; compare, in real time, by means of a signal point-to-point comparison algorithm, said parameter for the detected movement (Ctr) with said parameter of the reference cyclic movement (C ref) calibrated to determine whether the result of the comparison is between the tolerance limits; and trigger feedback via the feedback device when said parameter for the detected movement goes outside the margin of error defined by the tolerance limits; record a reference cyclic movement specific to the individual and minimum and maximum tolerance limits for a parameter of the movement to be monitored, the tolerance limits being specific to the individual and changing depending on their progress, the tolerance limits of the movement parameter being dynamic limits so as to define a curve of minimum values and a curve of maximum values surrounding the curve followed by the movement parameter of the reference cyclic movement; detect, by means of the sensor, said cyclic movement of the body segment; from a plurality of cycles of the detected cyclic movement, calculate the average duration of a cycle and calibrate the reference cyclic movement with said average duration; from measurement data of said sensor, calculate said parameter for the detected movement; compare, in real time, by means of a signal point-to-point comparison algorithm, said parameter for the detected movement (Ctr) with said parameter of the reference cyclic movement (C ref) calibrated to determine whether the result of the comparison is between the tolerance limits; and trigger feedback via the feedback device when said parameter for the detected movement goes outside the margin of error defined by the tolerance limits; - the feedback device being coupled to said processor and being suitable for providing the individual with real-time information on the compliance of the parameter of the detected movement with respect to the parameter of said reference cyclic movement.
