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.
