Key result
Experimentally induced deep and superficial pain both caused significant increases in muscle sympathetic nerve activity (43.9% and 38.2%, respectively), blood pressure, and heart rate.
Why the study?
Does deep pain compared to superficial pain produce differential effects on muscle sympathetic nerve activity in human subjects?
Does deep pain compared to superficial pain produce differential effects on muscle sympathetic nerve activity in human subjects?
Absolute Event Rate: 43.9% vs 38.2%
Both deep and superficial acute pain increase muscle sympathetic nerve activity, blood pressure, and heart rate, challenging the historical belief that deep pain causes vasodepression.
No takes yet. Share an insight, caveat, or question.
Should not yet change clinical pain management; challenges historical deep-pain vasodepression views and leaves mechanisms open for confirmation.
Burton et al. (2008) studied this question. Experimentally induced deep muscle pain vs. Experimentally induced superficial skin pain was evaluated on Muscle sympathetic nerve activity (MSNA). Experimentally induced deep and superficial pain both caused significant increases in muscle sympathetic nerve activity (43.9% and 38.2%, respectively), blood pressure, and heart rate.
