In the last 50 years the proportion of time spent in physical activity versus being sedentary has changed, particularly in developed countries. .
Prolonged seated immobility with long distance air travel is well-accepted as a risk factor for Deep Vein Thrombosis (DVT) which can lead (in severe cases) to pulmonary embolism (PE). [2-4]
An association between prolonged periods of sitting and blood clot risk was ﬁrst identiﬁed in the early 2000’s [4,5-9] and in a series of case-control studies the increased risk was close to 2.5 times greater than that of the general population. [10–12].
The RBR legﬂow™ is a small medical device that sits on the ﬂoor under foot, incorporating two separate round domes with patented nodules®, each large enough to accommodate the user’s foot. Through 3 simple exercises, the RBR legﬂow™ improves lower limb blood ﬂow in the popliteal vein by 11-fold (63.3cm/s in the popliteal vein versus 4.6cm/s) in adults seated in oﬃce chairs through active movement of the foot and consequent increased blood ﬂow in the calf. 
“Studies have shown that popliteal venous ﬂow reduces by 40 to 50% within 90 minutes of sitting” [14,15].
The RBR legﬂow™ is effective in all markets where long periods of inactivity are unavoidable. This can include travelling by air, working in an office, being hospitalised, online gaming, recovering from an operation or simply if you spend large amounts of leisure time sat still.
In all these cases, the RBR legﬂow™ should be with you.
