Materials and methods
Plantar pressure distribution of 93 subjects (42 subjects with CAI, 21 copers and 29 healthy subjects) was registered during barefoot walking and running. Data was collected on a 20m long runway with a Footscan® pressure plate imbedded on top of a forceplate (AMTI). Medio-lateral ratios were calculated for the five distinct moments and during the four phases of the stance phase. Temporal data, peak pressure, mean force and impulse for the different zones of the foot were also calculated.
Statistical analysis did not show significant differences between the groups for any of the tested parameters nor for the medio-lateral ratios at the different moments and during the phases.
This study does not confirm the results of previous studies suggesting a more lateral pressure distribution. Further research is needed.
