    Abstract

    A force-sensing platform (FSP), sensitive to changesof the postural control system was designed. The platform measuredeffects of postural perturbations in static and dynamic conditions.This paper describes the implementation of an FSP usingforce-sensing resistors as sensing elements. Real-time qualitativeassessment utilized a rainbow color scale to identify areas withhigh force concentration. Postprocessing of the logged data providedend-users with quantitative measures of postural control.The objective of this research was to establish the feasibility of usingan FSP to test and gauge human postural control. Tests wereconducted in eye open and eye close states. Readings obtained weretested for repeatability using a one-way analysis of variance test.The platform gauged postural sway by measuring the area of distributionfor the weighted center of applied pressure at the foot.A fuzzy clustering algorithm was applied to identify regions of thefoot with repetitive pressure concentration. Potential applicationof the platform in a clinical setting includes monitoring rehabilitationprogress of stability dysfunction. The platform functions as aqualitative tool for initial, on-the-spot assessment, and quantitativemeasure for postacquisition assessment on balance abilities.
