Autonomic arousal frequently is assumed to be a component of the pain response, perhaps because physiological mechanisms connecting pain and autonomic reactivity can be easily conceptualized. The evidence clarifying autonomic responses specific to painful stimulation, however, has been rather sporadic and lacks coherence; thus, a summary and ...

The autonomic nervous system, in particular the autonomic stress response, might modulate central pain processing in this population. Objectives: The goal of this study was to compare the autonomic response to acute painful stimuli in patients with chronic WAD and healthy controls and to look for associations between endogenous analgesia and ...

2023年7月4日 · The role of the autonomic nervous system (ANS) in chronic pain (CP) and in its chronicity is considered secondary and reactive to the nociceptive processes in the somatic nervous system (SomNS). However, research and clinical data strongly suggest the opposite. The ANS is an ancient, complex and ample part of the nervous system.

2020年2月26日 · Neural networks involved in pain processing are intimately linked to the autonomic nervous system (ANS) (Benarroch, 2006): On the one hand, the body’s response to pain is defined by changes in ANS parameters (Kyle and McNeil, 2014); on the other, alterations in autonomic arousal can also influence the experience of pain (Terkelsen et al., 2004).

2022年12月14日 · Autonomically mediated pain (AMP) is a component of neuropathic pain controlled by the two divisions of the autonomic nervous system. Sympathetically mediated pain (SMP) is identified clinically as pain that does not follow a specific dermatomal distribution but can be relieved through sympathetic efferent blockade. 1 The parasympathetic ...

When noxious stimuli impinge upon the body from external or internal sources, information regarding the damaging impact of these stimuli on bodily tissues is transduced through neural pathways and transmitted through the peripheral nervous system to the central and autonomic nervous systems.

Autonomic responses are controlled by the central autonomic network (CAN). Little research has examined sympathetic reactivity and associations with brain CAN structures in the presence of chronic pain; thus, the present study aims to investigate how chronic pain influences sympathetic reactivity and associations with CAN brain region volumes.

1 天前 · Background Assessing heart rate variability (HRV) before a standardized surgery would help to explore further the relationship between the autonomic nervous system and pain. Methods A single-center prospective cohort of 117 patients (55% female) scheduled for third molar extraction underwent a preoperative resting measurement of arterial pressure followed by an HRV recording, then potentiated ...

3 天之前 · In the CAN model, the ANS is involved in the modulation of autonomic outputs in response to pain, emotional, and behavioral stimuli. These autonomic regulatory structures are functionally highly correlated with cardiac function [18, 24, 25]. Riganello et al. conducted a quantitative assessment of the markers associated with the CAN.

2020年2月27日 · There are bi-directional interactions between the autonomic nervous system (ANS) and pain. This is likely underpinned by a substantial overlap between brain areas of the central autonomic network and areas involved in pain processing and modulation.
