Extremity therapy apparatus configured to maintain an extremity in a suitable geometry for performing extremity therapy. The extremity therapy apparatus includes two or more arcuate members which are radially repositionable about a common vertical axis with a support member and/or base member. Each arcuate member is configured to maintain a radial element in a suitable geometry with the extremity for performing the extremity therapy by providing a bias force or movement inhibition in opposition to movement of at least a joint associated with the extremity undergoing the extremity therapy.
