Secondary hyperalgesia vs allodynia

Increased pain sensitivity in normal skin surrounding a site of tissue damage is called secondary hyperalgesia. Hyperalgesia was traditionally defined as the psychophysical correlate of sensitization (either peripheral or central) of the nociceptive system. Se hela listan på physio-pedia.com Primary hyperalgesia describes pain sensitivity that occurs directly in the damaged tissues. Secondary hyperalgesia describes pain sensitivity that occurs in surrounding undamaged tissues. Opioid-induced hyperalgesia may develop as a result of long-term opioid use in the treatment of chronic pain.

Primary hyperalgesia - pain and sensitivity in the damaged tissues. Secondary hyperalgesia - pain and sensitivity that occurs in area around the damaged tissues. In an early definition hyperalgesia was considered “a state of increased intensity of pain sensation induced by either noxious or ordinarily nonnoxious stimulation of peripheral tissue.”.

Neuropathic pain syndromes are characterised by the occurrence of spontaneous ongoing and stimulus-induced pain. Stimulus-induced pain (hyperalgesia and allodynia) may result from sensitisation processes in the peripheral (primary hyperalgesia) or central (secondary hyperalgesia) nervous system.

Considerable progress has been made in developing clinically relevant animal models for identifying the most significant underlying mechanisms. This review deals with experimental models that are currently used However, their relative sensitivity at detecting allodynia is poorly understood. The purpose of this study was to compare the sensitivity of brush allodynia against Semmes–Weinstein monofilament technique for detecting allodynia within regions of secondary hyperalgesia in humans. Hyperalgesia Hyperalgesi Svensk definition.

II. III. IV. V. VI. Allodynia defines a state in which non-noxious stimulation is perceived as being painful. Allodynia is commonly observed following severe or extensive injuries, Negative numbers correspond to those secondary zones that remained within the ulnar nerve territory. Extraterritorial mechanical allodynia or hyperalgesia Secondary hyperalgesia was produced by an intradermal injection of capsaicin ( 50 μg) into the volar forearm of Punctate hyperalgesia versus allodynia?

Hyperalgesia, allodynia, and "dysesthesia" often add to the discomfort for patients. 5 Diagnostics The diagnosis is determined by patient history and clinical presentation [flexikon.doccheck.com] An 80-year-old female diagnosed with PHN presented with severe left intercostal allodynia and hyperalgesia up to the root of the fourth to tenth thoracic dermatome. 2014-11-11 2017-01-01 2014-06-09 This work analyzes the role of cholecystokinin (CCK) receptors, dynorphin A₁₋₁₇ and descending facilitation originated in the rostral ventromedial medulla (RVM) on secondary allodynia and hyperalgesia in formalin-injected rats. Formalin injection (50 μL, 1%, s.c.) produced acute nociception (lasting 1 h) and long-term secondary allodynia and hyperalgesia in ipsilateral and Intradermally injected capsaicin induces secondary mechanical hyperalgesia and allodynia outside the primary (i.e., capsaicin-injected) site.

Secondary hyperalgesia is characterized by a leftward shift of the stimulus-response function for noxious mechanical stimuli. (dynamic hyperalgesia, allodynia) and were only sufficient to For pain evoked by stimuli that usually are not painful, the term allodynia is preferred, while hyperalgesia is more appropriately used for cases with an increased response at a normal threshold, or at an increased threshold, e.g., in patients with neuropathy. Hyperalgesia and allodynia may be associated with either nociceptive pain or neuropathic pain, depending on the circumstances surrounding the development of the pain condition. The word hyperalgesia means an increased response to a painful stimulus. Static Allodynia: This is a form of mechanical allodynia that results from light pressure applied to the skin.

Stimulus-induced pain (hyperalgesia and allodynia) may result from sensitisation processes in the peripheral (primary hyperalgesia) or central (secondary hyperalgesia) nervous system.

23 Jan 2015 Secondary hyperalgesia is inducible in most individuals and is attributed to the secondary hyperalgesia in high- vs. low-sensitization responders. Increased activation has been observed in allodynia [42] and has be

Allodynia and hyperalgesia in neuropathic pain: clinical manifestations and mechanisms Troels S Jensen, Nanna B Finnerup 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. Both are seen in

Bupivacaine injected subcutaneously at the nuchal midline before surgery was also effective in abbreviating primary and secondary allodynia, with no signs of … 1999-07-01 Formalin-induced long-term secondary allodynia and hyperalgesia are maintained by descending facilitation.
