Relevance of stiffness of compression material on venous hemodynamics and edema

Elastic and inelastic stockings or bandages may provide the same degree of compression pressure in the resting supine position but inelastic material provides much greater compression pressure in the standing or working position. For elastic compression to have the same effect in the standing or exercising state would require a degree of compression in the resting position that would be intolerable. Studies have shown that this applies to reduction of reflux and improved venous pumping although both appear to have a similar effect for reducing edema.
