Why the study?
Does axillary blockade with bupivacaine alter brain activation patterns during rhythmic handgrip?
Does axillary blockade with bupivacaine alter brain activation patterns during rhythmic handgrip?
Neural feedback from contracting muscles is not necessary for the activation of motor and cerebellar areas during rhythmic handgrip, suggesting a central feed-forward mechanism in cardiovascular regulation.

Supports central feed-forward cardiovascular control during handgrip; hypothesis-generating at Level 5 and should not yet change practice.
Nowak et al. (1999) studied this question.
