The danger of prolonged sitting without elevation of the lower extremities or movement of the legs has been stressed as a cause of venous and arterial thrombosis of the leg vessels. Homans1 emphasized the frequency of thrombosis of the deep leg veins as a result of prolonged sitting, especially in automobiles. Tall men are peculiarly susceptible to venous thrombosis after long motor trips.2 During World War II, Simpson3 noted 21 sudden deaths from pulmonary embolism in persons in or leaving air-raid shelters. The cause was noted to be venous thrombosis of the legs, resulting from long periods of sitting on chairs or benches with the edges compressing the veins.
