Secondary hyperalgesia, which develops in uninjured tissue surrounding the site of injury, exhibits symptoms similar to those seen in chronic pain patients and is

Secondary hyperalgesia mechanism

Secondary hyperalgesia, caused by sensitization of dorsal horn neurons, occurs in the undamaged area surrounding the injury. Examples of neuropathic pain include: monoradiculopathies, trigeminal neuralgia, postherpetic neuralgia, phantom limb pain, complex regional pain … The effect of varying frequency and intensity of transcutaneous electrical nerve stimulation on secondary mechanical hyperalgesia in an animal model of inflammation. King EW(1), Sluka KA. Author information: (1)Graduate Program in Physical Therapy and Rehabilitation, Neuroscience Graduate Program, College of Medicine, University of Iowa, Iowa City, 52242, USA. The focus of this study is to examine the analgesic effects of electroacupuncture (EA) on capsaicin-induced secondary hyperalgesia, which represents central sensitization. Capsaicin (0.1%, 20 μl) was injected into the plantar side of the left hind paw, and foot withdrawal thresholds in response to von Frey stimuli (mechanical sensitivity) were determined for both primary and secondary Primary hyperalgesia usually occurs to both thermal and mechanical stimuli, and is caused (at least in part) by primary afferent nociceptor sensitization. Primary hyperalgesia results from the direct effects of injury to skin and nerve tissue, whereas secondary hyperalgesia involves the increased pain sensitivity of the surrounding tissue.

Secondary hyperalgesia areas:Secondary hyperalgesia areas assessed 100 min illustrated the ecological protection technique advantage and mechanism. The second paper from my PhD is now online . A novel addition to pain mechanism research in insertional Achilles Contralateral mechanical hyperalgesia and altered pain modulation in men who have unilateral insertional Achilles Intraoperative use of opioids may be associated with postoperative hyperalgesia evidence of positive effects for lidocaine administration on secondary outcomes However, its mechanisms of action remain unclear, despite its different.

9 Jun 2014 Additionally, areas of flare and secondary hyperalgesia were mapped of analgesia and anti-hyperalgesia mechanisms related to thermal and

2020-05-01 · Its mechanism of action is thought to be through inhibition of cyclooxygenase enzymes (COX-1 and COX-2), key enzymes in the biosynthesis of prostaglandin (PG)s [ 7 ], which sensitize nociceptors in the peripheral and dorsal horn neurons in the spinal cord [ 8 ]. These results indicate that the characteristics of primary and secondary hyperalgesia differ and also suggest that the mechanism for hyperalgesia to mechanical and thermal stimuli differ. Characteristics of primary (within the area of injury) and secondary (outside the area of injury) hyperalgesia were determined after a heat injury applied to the glabrous skin of the hand in 8 human volunteers.

Gov't; Review; MeSH terms. Animals; Humans; Hyperalgesia/etiology* Secondary hyperalgesia occurs outside the injury site and is characterized by mechanical hyperalgesia only. Hyperalgesia in inflammatory processes corresponds to primary hyperalgesia. Hyperalgesia in referred pain and neuropathic pain resembles secondary hyperalgesia (Table 3).

Secondary hyperalgesia is characterized by a leftward shift of the stimulus-response function for noxious mechanical stimuli. Secondary hyperalgesia is defined as an increase in pain sensitivity when a noxious stimulus is delivered to a region surrounding, but not including, the zone of injury (increased pain sensitivity outside of the area of injury or inflammation). Secondary hyperalgesia is due to central neuron sensitization and requires continuous nociceptor input Multiple mechanisms of secondary hyperalgesia. Treede RD(1), Magerl W.
