Figure 3 Schematic diagram of plantar pressure distribution between normal (A) and CAI patients (B) during walking(A) Normal individual; (B) CAI patient. The purple line stands for longitudinal axis of the foot, passing through the midpoint of heel and the midpoint of the 2nd and 3rd metatarsal heads. The dashed line composed of black dots represents the COP trajectory. The figure shows that the COP trajectory of CAI patients is shifted to the lateral side of the foot compared to normal individuals. Scientific Footscan® software (RSscan International®, Belgium) was used for creation of the figure.
