Variable Stiffness Prosthetic Foot

The experimental protocol provided to record for two minutes two IMUs channels assembled on a variable stiffness prosthetic foot (one on the main body of the prosthesis and the other on the ankle), 3-axis linear accelerations (ax , ay and az) and 3-axis Euler angles (θx , θy and θz), at 100 Hz for seven activities (walking, fast walking, stand, stairs and ramps ascending and descending) under different Dx slider configurations (Dx = 42, 45, 48, 51, and 54 mm), i.e. stiffness settings.
