Abstract

Abstract An adjustable therapeutic leg support device is provided including a pair of vertical end panels spaced parallel to one another, each end panel having a plurality of apertures. An upper and a lower leg support panel extend transversely between said end panels. A pivotal hinge connects one edge of the upper leg support panel to one edge of the lower leg support panel and has a hinge rod extending through the hinge and through an opposing aperture in each end panel. An upper leg adjusting rod extending through and between opposing apertures in each end panel upon which a portion of the upper leg support panel rests. A lower leg adjusting rod extends through and between opposing apertures in each end panel upon which a portion of the lower leg support panel rests. The hinge rod and the two adjusting rods are independently positionable in any pair of desired apertures contained in the end panels allowing the height of the support panels to be fully adjustable and the angle of each support panel to be fully adjustable, all independently of one another.
