Figure 6

Example of the plantar pressure distribution recorded by the insole system at the beginning of the gait cycle (A). The pressure sensing grid indicates a high load on the heel side (yellow) and a low load on the toe side (blue). White circles through the red line show the average point through which pressure is applied, while the red line illustrates the path followed by center-of-pressure (CoP) based measures over one step. Corresponding profile of CoP data from the same step for this patient, including few extracted features such as the medial–lateral (ML) and anterior–posterior (AP) distances, the CoP line length in blue, the area under the curve in grey and the CoP length in red (B).
