“…However, they often misinterpret the energetic cost of walking. In contrast, the six determinates of the gait allow a better estimation of the CoM energy, but do not produce an accurate kinematics of the motion [16,20,21,31,42,[54][55][56][57][58][59][60][61][62][63]. Thus, the available balance models use a hybrid inverted pendulum model that is supported by a dynamic model of the step-to-step transition, which requires knowledge of the ground reaction forces [16,20,21,31,42,54,[56][57][58][59][60][61][62][63].…”
