Concurrent handgrip may blunt Valsalva baroreflex responses; leaves open standardization of combined autonomic testing.
Does concurrent sustained handgrip modify the cardiovascular response to the Valsalva manoeuvre in normal and hypertensive subjects?
The baroreflex response to the Valsalva manoeuvre is modified, but not overridden, by concurrent sustained handgrip, indicating that Valsalva should be avoided during handgrip testing.
Ewing et al. (1976) studied this question.
