Body Posture-Related Differences in Pain Perception and Their Mediation by Cardiovascular Factors
Pain modulation arising from the cardiovascular system has repeatedly been described. It is mediated by the baroreceptor system, where the activity of baroreceptor afferents inhibits nociception. Body posture changes cause blood volume redistribution that might modulate baroreceptor activity and antinociceptive effects. This study investigated posture-related differences in pain perception and their causation by cardiovascular factors. Pressure pain threshold and tolerance and pain intensity…
