Abstract
A prosthetic foot can have an ankle unit with semi-active adjustable stiffness. In one example, the adjustable stiffness is in the sagittal plane. The ankle stiffness can be varied by the ankle unit in response a user input, which can be received via a wireless communication device. The ankle unit can include two load application locations for one or more cantilever springs so as to provide different stiffness in plantarflexion and dorsiflexion. The positions of the two load application locations can be varied in order to vary the stiffness.
