Mechanistic research on neuropathic pain frequently uses human surrogate models of the secondary hyperalgesia that is a common feature of neuropathic pain. Experimentally induced secondary hyperalgesia has been manipulated with pharmacological and non-pharmacological After heat stimulation the area of secondary hyperalgesia was quantified with a foam brush (allodynia) and a 26 g von Frey hair (mechanical hyperalgesia) by stimulating the skin distant from the treated area and slowly moving inward until the subject indicated the stimulus had become noxious or until the subject reported a definite change in sensation (i.e., burning, tenderness, more intense pricking).

Secondary hyperalgesia is indicative of central sensitization. [1] Because secondary hyperalgesia is short-lived, persistent pain after surgery in large part may be primary hyperalgesia, perhaps amplified by central sensitization. The authors thank David Kramer for technical assistance during these experiments and Drs. Corey L. Cleland and Gerald F. Gebhart for reviewing the manuscript. Along with the primary hyperalgesia that results from activation of peripheral nociceptors in response to injury, secondary hyperalgesia occurs in the areas around the injured site as a result of The development of mechanical hyperalgesia, both primary and secondary, after experimental skin incision has recently been documented in detail in human volunteers.29A number of patient studies have demonstrated various forms of nociception-induced hyperalgesia postoperatively using QST10,34,36(for review of studies up to 1999, see Wilder-Smith34).

We present the case of a patient on large amounts of intrathecal opioids for chronic pain syndrome with opioid induced 2016-05-31 2014-04-25 To observe the mechanical and thermal hyperalgesia of mice, we subjected the mice to von Frey filament detection and a thermal pain test on day 7, 14, 21, 28, 35, and 42 after drug administration. We examine the effect of morphine or ketamine (N-methyl-D-aspartate receptor antagonist; NMDA) treatment on secondary hyperalgesia. Drug treatment started preinjury and continued into the early postinjury period. Hyperalgesia was induced by a local 1 degrees burn injury covering 12.5 cm (2) on the medial side of the calf. ASA is therefore a clinically useful analgesic drug for treatment of secondary hyperalgesia in OA. These findings suggest that ASA may have the ability to attenuate secondary hyperalgesia through suppression of ASIC3 and/or TNF-α expression. Secondary hyperalgesia is due to central neuron sensitization and requires continuous nociceptor input from the zone of primary hyperalgesia for its maintenance. Secondary hyperalgesia implies only mechanical hyperalgesia, i.e.

The terms “hyperalgesia” and “allodynia” are widely used in the following text. Hyperalgesia is an increased pain sensitivity to a peripherally applied stimulus [5]. Pri-mary hyperalgesia is an increased pain sensitivity at the site of injury, which is thought to mirror changes in the peripheral nervous system.

injections of capsaicin (40 ug in 13 ~1) were given into the radial nerve territories of the left hand after complete block of A-fiber nociceptors (A) Treatment. Hyperalgesia is similar to other sorts of pain associated with nerve irritation or damage such as allodynia and neuropathic pain, and consequently may respond to standard treatment for these conditions, using various drugs such as SSRI or tricyclic antidepressants, Nonsteroidal anti-inflammatory drugs (NSAIDs), glucocorticoids, gabapentin or pregabalin, NMDA antagonists, or atypical opioids such as tramadol. How precise does the Max. VAS-score following Long Thermal Stimulation evaluated on the 4 experimental days predict the size of the area of secondary hyperalgesia on the respective 4 experimental days? 4 sessions of Long Thermal Stimulation on 4 separate experimental days with 1 session per experimental day. Secondary hyperalgesia refers to the sensitization that occurs because of changes in spinal cord processing. For example, through a process of central sensitization, the firing of dorsal horn nociceptors can change dramatically in the setting of injury (produced by either tissue or nerve damage). Hyperalgesia means increased sensitivity to painful or to normally non-painful stimulation.

Multivariate regression analysis was conducted to examine whether stressful life event scores would predict the two correlated outcome variables: area and intensity of secondary hyperalgesia (Pearson r = .49, p = .006). Tis study was designed to test the hypothesis that pretreatment with valdecoxib, prior to injury could reduce or prevent the development of secondary hyperalgesia around the area of primary injury. A heat/capsaicin model of induced hyperalgesia was tested in healthy volunteers in a randomized, double blind, cross-over trial of a single dose of 40 mg vadecoxib versus control. 2020-01-01 · As indicated in Fig 4F–H, subcutaneous treatments with the interfering, but not control, virus resulted in a time-dependent attenuation of secondary hyperalgesia (von Frey Test-V2: two-way ANOVA and Sidak's test, pT-ION+AAV-Cavα2δ1-Int virus vs. pT-ION+AAV-control virus, F 1,16 = .2011, P = .6598; von Frey Test-V3: two-way ANOVA and Sidak's test, pT-ION+ AAV-Cavα2δ1-Int virus versus pT Preoperative chronic pain and opioid consumption are risk factors for severe postoperative pain and persistent postoperative pain. 1–4 The demonstration of diffuse hyperalgesia in a nonsurgical context has provided evidence of central sensitisation, both in patients with chronic osteoarthritis pain 5 and in patients on long-term morphine treatment.

In order to define the afferent pathways involved in inducing central Secondary hyperalgesia refers to the sensitization that occurs because of changes in spinal cord processing.
