A device for analyzing the regularity and symmetry of a sequence of N gait or running cycles of a person, comprising sensors for measuring raw time signals of a physical movement variable of a body segment, a processing unit connected to the sensors for measuring and configured to separate the raw time signals into distinct time signals Ci, the Ci series being associated with a given gait or running cycle i of the person, to calculate at least one similarity coefficient between the signal Ci associated with gait or running cycle i and another signal Cj associated with a gait or running cycle j of the person. A display is configured to display the matrix M(i,j) with each value of the similarity coefficient shown in the matrix M(i,j) in color to form a graduated color scale indicating the similarity between the gait or running cycles i and j.

Locogram software: tool for analysing gait exercises

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.

Method for quantifying balance

A method is provided for characterising a gait comprising steps of: receiving a signal measuring the movement of a target subject measured beforehand; comparing () at least one section of the measuring signal with a plurality of reference signals, the plurality of reference signals comprising at least one movement signal measured beforehand on a reference subject different from the target subject, each comparison of the measuring signal with a reference signal producing a similarity coefficient representative of a probability of similarity between the compared signals; and selecting () at least one local maximum of interest among the similarity coefficients produced, wherein the plurality of reference signals comprises at least one movement signal measured beforehand on a reference subject afflicted with a gait disorder, and at least one movement signal measured beforehand on a healthy reference object.
