• Blood Flow Restriction (BFR) is the application of external pressure over the extremities. The applied pressure is sufficient to maintain arterial inflow while occluding venous outflow distal to the restriction site. The goal is to make greater strength gains while lifting lighter loads, reducing the overall stress placed on the limb. 

    **A study by Loenneke in 2010 concluded; BFR when used in a controlled environment by trained and experienced personnel, provides a safe training alternative for most individuals regardless of age and training status.**

    **Study by Hughes in 2017, concluded: BFR had no greater risk than traditional exercise.**

    Risks for Blood flow restrictions are low; and we take steps to limit occurrence.  They include but are not limited to:  

    • The most common risk to BFR is sciatic nerve irritation.
    • The most serious risk is excessive muscle damage (i.e., rhabdomyolysis) but occurrence to be <0.01% 
    • Numbness of limb, incidence is low (<2%); likely due to inappropriately high tourniquet pressures
    • Incidence Deep venous thrombosis (DVT) <.06% and pulmonary embolism (PE) was <.01%
      • One studied showed the DVT occurrence was less than the general population
      • Other studies showed that BFR restrictions do not cause DVTs
    • With BFR there is a possibility of an intensified exercise pressure reflex with result in excessive blood pressure elevation.
