Why the study?
What is the relative contribution of the venoarteriolar response, myogenic reflex, and hemodynamics to the decrease in local blood flow induced by venous congestion?

Venous congestion induced by limb dependency is a more specific method to quantify the venoarteriolar response than cuff inflation, which also reduces local perfusion pressure.
No takes yet. Share an insight, caveat, or question.
Limb dependency may more specifically isolate venoarteriolar response than cuff inflation; hypothesis-generating for venous congestion mechanisms.
Okazaki et al. (2005) studied this question.
