为了更好地将人类足部的形式和运动置于进化背景下，了解四足动物两足行走时足部运动如何变化可以提供信息。为此，我们比较了足部下方的压力。在日本猕猴（Macaca fuscata）的两足和四足行走过程中。使用压力垫（120 Hz）记录9个足底区域的压力，同时动物以其首选速度在水平人行道上行走。结果显示，两种运动模式之间的足部使用存在实质性差异，在双足行走期间观察到的一些特征类似于人类步态，例如压力中心（COP）的内侧转移，前足压力的突然下降以及拇趾下方的压力增加，所有这些都发生在后期站立阶段。在倭黑猩猩身上也能观察到（Vereecke等，Am J Phys Anthropol 120（2003）373-383），是由于后肢主导步态的生物力学要求，例如双足行走，还观察到与人类运动完全不同的双足和四足运动所共有的特征，脚跟从未接触地面，没有足纵弓，拇趾广泛外展，功能轴位于第三趾，而不是第二趾，Am J Phys Anthropol 142 149-156，2010（C）2009 Wiley-Liss，Inc
To better place the form and motion of the human foot in an evolutionary context, understanding how foot motions change when quadrupeds walk bipedally can be informative For this purpose, we compared the pressures beneath the foot. during bipedal and quadrupedal walking in Japanese macaques (Macaca fuscata). The pressure at nine plantar regions was recorded using a pressure mat (120 Hz), while the animals walked on a level walkway at their preferred speeds. The results revealed substantial differences in foot use between the two modes of locomotion, and some features observed during bipedal walking resembled human gait, such as the medial transfer of the center of pressure (COP), abrupt declines in forefoot pressures, and the increased pressure beneath the hallux, all occurring during the late-stance phase In particular, the medial transfer of the COP, which is also observed in bonobos (Vereecke et al Am J Phys Anthropol 120 (2003) 373-383), was due to a biomechanical requirement for a hind limb dominant gait, such as bipedal walking Features shared by bipedal and quadrupedal locomotion that were quite different from human locomotion were also observed, the heel never contacted the ground, a foot longitudinal arch was absent, the hallux was widely abducted, and the functional axis was on the third digit, not the second Am J Phys Anthropol 142 149-156, 2010 (C) 2009 Wiley-Liss, Inc
