Presentation

  • Jeff - Cart and pendulum modeling of stiffness (does it predict stance width data?)
    • Motivation
      • People ignore passive response...how much does passive response affect total response (including feedback)
    • Observation
      • We see changes in behavior for different stance widths.
      • CoM acceleration, EMG activity
    • Hypothesis
      • How much does passive response alter the response to a perturbation?
    • Prediction
      • The initial response is dictated largely by passive "feedforward" state of the system.
    • Methods
      • Look at CoM acceleration
      • Make sure to look at time windows that are relevant.
