Supports interchangeable arm or leg sympathetic recordings during mild orthostatic stress; leaves open extension to clinical populations.
Does lower body negative pressure increase muscle sympathetic nerve activity similarly in the arm and leg in healthy subjects?
Mild to moderate orthostatic stress induced by lower body negative pressure causes nearly identical increases in sympathetic outflow to the arm and leg.
Rea et al. (1989) studied this question.
