The step cycle for a G1 ‘pacing walk’ for three different duty factors (DF). For DF = 0.5 and 0.6 the right manus is in transition and must have its position interpolated. For DF ≥ 0.625 all four limbs are in ground contact. As in Fig. 13, the dashed black line indicates α-phase \({\phi }_{\alpha }\) the relative phase between MR and PL
