Biomechanics - Locomotion

Intersectional Research Projects

• Stability of Gait
  Walking on two legs is inherently unstable. Still, we humans perform remarkable well at it, mostly without falling. We measure and perturbed walking to gain more insight into the role of the central nervous system in controlling gait stability.
• Active control and passively stable patterns
  Building on research on kinematic measures and neural correlates of gait stability, we hypothesize that several distinct phases of the gait cycle require active control.
• Sensory information for control of gait stability
  In this project we study how the brain can estimate the kinematics of the body center of mass during walking from sensory information to control foot placement in order to maintain gait stability.
• Energetics of Locomotion
  Humans usually walk in a way that is energetically optimal. However, small changes to the gait pattern, such as alterations in arm swing, step length, or step width, change the metabolic energy required for walking. In this project we investigate how these small changes affect energetic cost of locomotion, and whether we can use these changes to understand how much energy is used for propulsion and maintaining stability.
