2017, Gait and PostureCitation Excerpt :Recent studies have indeed shown that deliberately reducing CoM motion actually increases metabolic cost [17,18]. Studies have also shown that several of the determinants make negligible difference to CoM motion [20–22]. Additionally, the determinants have recently been assessed in the context of inverted pendulum walking [23], and have found the major cost of walking was attributed to redirecting the CoM during the step-to-step transitions [24].
Quantitative evaluation of the major determinants of human gait
2014, Journal of BiomechanicsCitation Excerpt :A number of studies have challenged some of these conclusions. Gard and Childress (1997, 1999) investigated the effects of pelvic list and stance knee flexion on the vertical displacement of the trunk and concluded that neither mechanism significantly reduces trunk vertical displacement. Using a circular rocker foot to simulate the stance phase of gait, these researchers found that anteroposterior translation of the center of pressure (COP) flattens the trajectory of the trunk in the sagittal plane (Gard and Childress, 2001).
Contribution of the six major gait determinants on the vertical center of mass trajectory and the vertical ground reaction force
2013, Human Movement ScienceCitation Excerpt :The results, however, showed a major contribution of the stance knee flexion and pelvic obliquity to the reduction of the amplitude of CoM vertical displacement during the phases of double support and midstance. Several authors (Gard & Childress, 1997, 1999; Kerrigan et al., 2001) have hypothesized through the process of evolution, knee flexion and pelvic obliquity of the stance limb have been mostly involved in the partial absorption of the mechanical shock generated by the foot strike, and in the rapid transfer of stance limb weight toward the contralateral limb during double support. This led to a decrease in the energy cost which would be much higher if the compass gait step-to-step transition was more abrupt (Kuo, 2007; Donelan, Kram, & Kuo, 2002).
