This study compared three different foot-pressure measurement methods to
investigate whether these measurement methods could or should be used
interchangeably. In-shoe pressure measurements using F-Scan system, shod and
unshod pressure measurements using the MatScan system were taken for each of the
21 healthy subjects while performing walking trials using a two-step gait
initiation protocol. Each foot was separated in three regions: forefoot (40%),
midfoot (30%) and rearfoot (30%) for further analysis.
The parameters researched
include average peak pressure, average peak force, timing and centre of pressure
displacement. The in-shoe condition produced the highest values for the average
peak force. However, the shod condition showed a trend for the highest average
peak pressure. The F-Scan system consistently demonstrated slower timing values
for all parameters, except one. Centre of pressure anterior/posterior trajectory
was considerably shorter for the in-shoe gait condition. Consequently, the data
cannot be extrapolated from one collection method to another. It is therefore
recommended that a standardised collection method is utilised when pressure
analysis is undertaken and that they are not used interchangeably.
