Abstract

Effects of variable cushion densities on human gait are estimated by analyzing principle components of Ground Reaction Force (GRF) which includes Vertical Ground Reaction Forces (VGRF), Moments (M) and Center of Pressure (COP). This biomechanics study aims to identify design and parameters for quantification of a prosthetic foot. VGRF is important to analyze dynamics of human gait and predict the quality of prosthetic foot, and more accurate estimation is possible by inclusion of lower limb moments and COP. Experimental GRF data of human gait with cushion pads of different densities under heal area is acquired through force platform. Recorded gait data is correlated for variation in VGRF, moments and COP with respect to variation in Cushion Densities (CD). It is observed that VGRF (FZ1, FZ3) and Moment (M1) decrease significantly with the increase in cushion densities. Similarly, VGRF (Fz2), Moment (M2, M3) and COP increase with the increase in cushion densities and that VGRF reduces for walking at normal speed with added cushion heel as compared to bare foot (without cushion pads) walking.
