Method for analyzing the stride of a walking pedestrian

A method for analyzing the stride of a walking pedestrian, the method comprising steps of:

• (a) Acquiring, during a recording period, motion measurements of a motion of a lower limb of the pedestrian,
• (b) Determining, by a data processing unit, each stride made by the pedestrian during the recording period, based on the motion measurements,
• (c) Dividing the recording period into recording sub-periods,
• (d) For several detected strides, estimating a characteristic quantity of the stride, based on the motion measurements, in which the characteristic quantity is or depends on a stride length,
• (e) Calculating, with respect to a set formed by the characteristic quantities estimated for the strides of the recording sub-period, ordered by increasing values, a percentile of the characteristic quantity for that recording sub-period, the percentile being chosen in a predetermined range of percentiles,
• (f) Repeating step (e) for several recording sub-periods,
• wherein the predetermined range of percentiles is comprised between the 70th and 100th percentile.
