- Demographics: Information about the height (in meters) and mass (kg) of the subject.
- Raw Marker Data: The x and y positions of various markers expressed in the global coordinate system. All dimensions are in meters.
- Force Plate Data: The x and y components of the ground reaction force, the free torque (you can ignore it for this problem), and the x location of the center of pressure (COP) (i.e., the point that represents the location of the GRF). All dimensions are in metric units (meters, Newtons, etc.).
Part 1: Kinematics
1. Please calculate and plot the hip, knee, and ankle flexion angles as a function of time. (Note that you have more than 1 gait cycle in the data file.) To do so, follow these steps:
