title: Influence of walking speed on gait parameters of bipedal locomotion in rhesus monkeys.
abstract: 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.
