The primate model of bipedal locomotion has been extensively used to study human evolution and played a critical role in exploring the pathological mechanisms of human neurologic disease and spinal cord injury. Speed has great influence on both walking posture and gait parameters in human walking; however, how speed changes the gait pattern of bipedal locomotion in primates remains unclear.
We chose six adult female rhesus monkeys (Macaca mulatta) and collected the gait parameters of these animals during their treadmill locomotion over a wide range of speed. Using a 3D motion analysis system, we studied the spatiotemporal characteristics of the gait pattern.
We have built an efficient and time-saving primate model and shown that speed significantly impacts kinematic parameters. This may present a thorough description of speed-related changes in the gait pattern of rhesus and shed light on the control of bipedal locomotion in primates.
双足行走的灵长类动物模型已被广泛用于研究人类进化，并在探索人类神经系统疾病和脊髓损伤的病理机制中发挥了关键作用。速度对人类行走的姿势和步态参数都有很大影响；然而，速度如何改变灵长类动物双足行走的步态模式仍不清楚。
我们选择了六只成年雌性恒河猴（猕猴），并收集了这些动物在跑步机上以广泛速度运动时的步态参数。使用三维运动分析系统，我们研究了步态模式的时空特征。
我们建立了一个高效且省时的灵长类动物模型，并表明速度显著影响运动学参数。这可能全面描述了恒河猴步态模式中与速度相关的变化，并为灵长类动物双足行走的控制提供启示。
