Abstract

The invention describes a method for analysing the stride of a walking pedestrian, comprising steps of: (a) acquiring, during a recording period, motion measurements of a lower limb (1) of the pedestrian, (b) determining each stride made by the pedestrian, (C) dividing the recording period into recording sub-periods, (d) for several detected strides, estimating a characteristic value of the stride, (e) selecting at least one characteristic stride value from a predetermined range of percentiles within a set formed by the estimated characteristic stride values, ordered by increasing values and occurring during a recording sub-period, (f) repeating step (e) for several recording sub-periods. The invention also concerns a piece of equipment (10) for analysing the stride of a walking pedestrian, and a computer program product.

Description

Technical field[0001]The invention relates to the field of analysis of the steps of walking pedestrians.Background technique[0002]A person's walking includes a sequence of one or more steps. Striding includes two stages: the first stage, during which the foot is in contact with the ground; and the second stage, during which the foot is in the air. Such asfigure 1 As shown, striding starts when one foot touches the ground and ends when the same foot touches the ground again.[0003]Walking requires the use and coordination of many muscles. The analysis of steps can therefore be used to characterize the health of an individual, especially the muscle strength that the individual can develop. This muscle strength may vary depending on many factors, such as fitness status, age, individual physical training or treatments taken by the individual that affect their muscle efficiency.[0004]The evolution of the characteristics of the pace over time can represent the evolution of the individual's...
