Description

My objective in this project is to determine optimal parameters for a linearly elastic assistive device in order to provide maximum metabolic assistance to a wide variety of users.

Research Questions

1. What does the landscape of metabolic cost look like when resting length and stiffness are varied for a single subject? What are the optimal values for these parameters? How big of an effect do small variations in each of the parameters have on the metabolic savings?
2. Do these optimal stiffness and resting length parameters vary between subjects or are they approximately the same when normalized by subject height and weight? How does speed affect the parameters?
3. Do kinematics change significantly when using the device? If so, how does changing kinematics induced by the device change muscle activation during the gait cycle?
