Presentation
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.
- Motivation
