As a method for the balance assessment. a steady-state response of a subject standing on the support surface oscillating horizontally back and forth at a single frequency has been studied. While past studies on the method have focused on the kinematic analysis investigating the center of mass (COM) motion. there has no research based on mechanical models. https://www.ealisboa.com/top-sale-AR-10-Vert-Monoband-Indep-10m-2-Ringo-quick-deal/
