This study investigated whether central sensitization has a significant effect on hyperalgesia after consecutive operations. 1999-07-06 Lack of secondary hyperalgesia and central sensitization in an acute sheep model. Mather LE(1), Cousins MJ, Huang YF, Pryor ME, Barratt SM. Author information: (1)Department of Anaesthesia and Pain Management, University of Sydney at Royal North Shore Hospital, St Leonards, NSW, Australia. lmather@med.usyd.edu.au 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. 2019-12-10 · The focus of spatial attention during the induction of central sensitization can modulate the subsequent development of secondary hyperalgesia.

Secondary hyperalgesia central sensitization

The secondary hyperalgesia elicited by a clinical pain model may thus be a result of central sensitization. Cen- The focus of spatial attention during the induction of central sensitization can modulate the subsequent development of secondary hyperalgesia. We investigated the effects of i.v. magnesium on secondary hyperalgesia following heat/capsaicin stimulation in human volunteers. Twenty-five volunteers were included in this double blind, randomized, crossover study. Sensitization was induced in the volunteers, who were then subjected to either i.v. saline or magnesium sulphate.

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 each of 8 sessions, 2 groups of healthy human subjects received a series of painful thermal stimuli that resulted in secondary hyperalgesia.

(secondary hyperalgesia). Secondary hyperalgesia shares clinical characteristics with neurogenic hyperalgesia in patients with neu-ropathic pain. Abnormal brain responses to somatosensory stimuli have been found in patients with hyperalgesia as well as in normal subjects during experimental central sensitization. The aim of this Allodynia (pain due to a stimulus that does not usually provoke pain) and hyperalgesia (increased pain from a stimulus that usually provokes pain) are prominent symptoms in patients with neuropathic pain.
