Abstract
Abstract A pair of foot attachments for performing leg exercises so as to facilitate efficient pumping action of blood from deep leg veins. Each foot attachment incorporates a high sock with a flexible foot panel connected by springs to a more rigid panel. The present invention permits its utilization by a patient in either a sitting position, as when the patient is sitting in a chair or on the side of a bed, or in a supine position, where the patients' calves can be positioned against a panel from which is hinged a second panel that provides a surface against which the rigid panels of the foot attachments are placed.
