The result of material properties, frictional coefficient and damping coefficient sensitivity analyses of the foot finite element model.

RMSE  =  root mean square error, rRMSE  =  relative root mean square error, F_x  =  horizontal component of ground reaction force, F_y  =  vertical component of ground reaction force, CoP  =  displacement of center of pressure, FRA  =  foot rotation angle, PRA  =  phalanx rotation angle, HP  =  plantar pressure in the heel medial region, MP  =  plantar pressure in the 1^st metatarsal region. The first three sets of parameters are material properties, and the final set involves altering the frictional coefficient from 0.6.
