目标在人类行走中，骨盆在支撑阶段向摆动侧倾斜，而胸部向站立侧倾斜。相比之下，黑猩猩在双足行走时，在支撑阶段骨盆和胸部都向站立侧倾斜，使得它们的体重波动比人类更大。然而，除了一些关于黑猩猩和猕猴的报道外，关于非人类灵长类动物双足行走期间躯干运动与步宽之间关系的研究还很有限。 材料与方法我们收集了五名人类和五只猕猴双足行走期间的三维躯干运动数据。行走时，定义躯干节段的簇标记的位置由多个摄像机记录。将节段 xyz 坐标数字化，并使用运动分析软件计算正面旋转和平移。结果安全比的运动学近似值（即相对于步宽的质量运动中心）在所有物种中都是相似的。然而，躯干内运动和步宽之间的关系因物种而异。讨论我们的结果支持这样的假设：人类额状面的躯干运动在类人灵长类动物中是独一无二的。因为无论习惯性还是兼性两足动物，安全比都在相似的范围内，这进一步支持使用化石足迹来估计质量运动中心。
ObjectivesIn human walking, the pelvis lists toward the swing side during the support phase while the thorax lists toward the stance side. In contrast, during bipedal walking in chimpanzees, both the pelvis and thorax list toward the stance side during the support phase, making their body mass oscillation larger than that in humans. However, aside from a few reports on chimpanzees and macaques, studies on the relationship between trunk movements and step width during bipedal walking in nonhuman primates are limited.Materials and MethodsWe collected three‐dimensional trunk kinematic data during bipedal walking in five humans and fiveMacaca fuscata. While walking, the positions of cluster markers, which defined trunk segments, were recorded by multiple video cameras. Segmental xyz coordinates were digitized, and frontal rotations and translations were calculated using motion analysis software.ResultsThe kinematic approximation of the safety ratio, which is the center of mass motion relative to the step width, was similar in all species. Nevertheless, the relationship between intratrunk movements and step width varied among the species.DiscussionOur results support the hypothesis that trunk movement in the frontal plane in humans is unique among anthropoid primates. Because the safety ratio is within a similar range, regardless of habitual or facultative bipeds, this further supports the use of fossil footprints to estimate the center of mass motion.
