Abstract
Commercially available devices objectifying the amount of pressure under the foot are often different in accuracy and reliability of results. The aim of this pilot study was to compare output values of plantar pressure within one step generated by the system Kistler and Footscan.
Software synchronization of both devices was performed and according to the subsequent evaluation it was found that the values of forces obtained from the device Footscan are lower than from the Kistler system. This linear correlation may be used only in the evaluation phase of the maximum loaded foot (peak area), in the phase of lightening foot from the ground, the system Footscan is burdened by significant mistake of measurement, probably due to nonlinearity in the mechanical properties of the surface of the measuring plate.
