that the development of secondary hyperalgesia to punc-tate mechanical stimuli following a standardised injury is caused by central changes in response to a conditioning stimulus and transmitted by A-delta fibers [1, 9–11]. The secondary hyperalgesia elicited by a clinical pain model may thus be a result of central sensitization. Cen-

was assessed as indicator of secondary hyperalgesia. Central sensitization was analyzed by measuring calcitonin gene-related peptide (CGRP) expression levels in the spinal dorsal horn. In the CPM group, the PPT was significantly increased compared with the IM group from 14 to 35 days, and PWR was significantly decreased from 14 to 56 days.

In the CPM group, the PPT was significantly increased compared with the IM group from 14 to 35 days, and PWR was significantly decreased from 14 to 56 days. 2015-01-23 · Secondary hyperalgesia is inducible in most individuals and is attributed to central neuronal sensitization. Some individuals develop large areas of secondary hyperalgesia (high-sensitization responders), while others develop small areas (low-sensitization responders). Secondary hyperalgesia to punctate mechanical stimuli. Central sensitization to A-fibre nociceptor input. Brain 1999; 122: 2245 –2257. 8.

In addition, CS entails much more than generalized hypersensitivity to pain: It is characterized Background and Objectives We aimed to determine the following in an experimental acute pain model in sheep: (1) whether multimodal analgesia with intravenous fentanyl and ketorolac was more effective than fentanyl alone; (2) whether secondary hyperalgesia (central sensitization) occurred in adjacent (foreleg) dermatomes after thoracic surgery; (3) whether ketorolac used preemptively influenced The focus of spatial attention during the induction of central sensitization can modulate the subsequent development of secondary hyperalgesia. 572.0KB.

The zone of secondary hyperalgesia caused by 25 Apr 2017 The effects of central sensitization extend beyond nociceptive pathways to other sensory modalities.

Secondary hyperalgesia is inducible in most individuals and is attributed to central neuronal sensitization. Some individuals develop large areas of secondary hyperalgesia (high-sensitization responders), while others develop small areas (low-sensitization responders).

Ketamine is an important drug for central temporal summation and inhibition of secondary mechanical hyperalgesia. This study investigated whether central sensitization has a significant effect on hyperalgesia after consecutive operations.

(2018) Hansen et al. PLoS ONE. Introduction Central sensitization plays a pivotal role in maintenance of pain and is believed to be intricately involved in several chronic pain conditions. One clinical manifestation of central sensitization is secondary hyperalgesia. The degree of secondary hyper sensitization and its modulation by the endogenous opioid system in humans.

HFS‐induced hyperalgesia is suitable to discriminate or compare individuals but it may not be sensitive to changes due to an intervention. Significance. It is crucial to evaluate central sensitization adequately in humans. This study formally establishes the reliability of secondary hyperalgesia induced by electrical high‐frequency stimulation. central (spinal) neurons, termed central sensitization.

27 Dec 2017 In addition to allodynia and hyperalgesia, central sensitization has some central sensitization once an injury occurs and the second group

The objective of this study was to investigate the association between areas of secondary hyperalgesia and volumes of the caudate nuclei and other brain structures involved in pain processing. Conclusions When subjects are observed across days, 'central sensitization', measured as the area of secondary hyperalgesia after a first-degree burn, does not seem to be important for clinical pain intensity per se, but may be important for clinical pain variation. Secondary hyperalgesia refers to the sensitization that occurs because of changes in spinal cord processing.

8 Sep 2012 with primary and secondary hyperalgesia, respectively. Data suggest the presence of central sensitization among subjects with chronic SIS.

The secondary hyperalgesia elicited by a clinical pain model may thus be a result of central sensitization. Cen- 2019-02-08 Central sensitization (CS) refers to an “increased responsiveness of nociceptive neurons in the central nervous system to their normal or subthreshold afferent input.” Clinically this corresponds with a heightened perception of pain stimuli (hyperalgesia) or the experience of pain after normally innocuous stimuli (). Some researchers speculate central sensitization to be the explanatory This phenomenon became known as primary hyperalgesia (Woolf, 2011). Primary hyperalgesia cannot explain the clinical symptoms of pain summation, allodynia, or secondary hyperalgesia. It was speculated that these changes had to occur from alternations in the receptor fields within the central … 2021-03-19 Introduction Central sensitization plays a pivotal role in maintenance of pain and is believed to be intricately involved in several chronic pain conditions.
