It is believed that secondary hyperalgesia (the increased sensitivity to mechanical nociceptive stimuli that develops after cutaneous tissue injury in the surrounding uninjured skin) is mediated by a subclass of nociceptors: the slowly adapting A‐fibre mechano‐heat nociceptors (AMH‐type I). Here we tested this hypothesis. By using intense long‐lasting heat stimuli, which are known to

5 juni 2018 — Glandular, ocular, and auricular Stress-related physiologic response to provoke referred pains, secondary hyperalgesia periodontal origin.

We have reevaluated the effects of local anesthetics on electricall Moreover, greater use of positive emotional words predicted reduced secondary hyperalgesia at 1 month (β = -0.71, p =.022). In contrast, disclosure had no effect on spontaneous pain. CONCLUSIONS: Disclosure modulates secondary hyperalgesia observed in women with trauma history, producing a short-term enhancement and a long-term reduction. Secondary hyperalgesia is believed to be a key feature of “central sensitization” and is characterized by enhanced pain to mechanical nociceptive stimuli. The aim of the present study was to charac Hyperalgesia to heat is prevalent after a cutaneous injury and after inflammation.

2001) in which large and stable areas of allodynia and punctate hyperalgesia are provoked for prolonged periods and are accompanied by a large axon reflex erythema. Intradermal microdialysis was employed to continuously deliver lidocaine in a narrow strip a length of 10 cm, thereby providing a stable and narrow anesthetic strip. Wind-up and secondary hyperalgesia both are related to central sensitization, but whereas the former is explained by homosynaptic facilitation, the latter is due to heterosynaptic facilitation. Abstract. 1. Psychophysical studies were made, in humans, of the sensory characteristics and underlying mechanisms of the hyperalgesia (often termed “secondary hyperalgesia”) that occurs in uninjured skin surrounding a local cutaneous injury.

Hyperalgesia also develops in a large area of uninjured skin surrounding the injury site (secondary hyperalgesia) and most likely is due to sensitization of neurons in the central nervous system. AB - Nociceptors are a specialized class of primary afferents that respond to noxious or injurious stimuli.
