Increased sensitivity to stimulation and does not imply a painful sensation. Hyperalgesia is a special case of hyperaesthesia. Hypoaesthesia. Decreased sensitivity 1 Sep 2014 Hyperalgesia, an increased pain induced by noxious stimulation of peripheral or extending beyond the site of injury (secondary hyperalgesia). hyperalgesia in undamaged tissue was due to central mechanisms within the 5 Apr 2021 Secondary hyperalgesia occurs when the pain feels as if it's spreading to a non- injured site of the body. Symptoms of OIH. The key symptom of 1.1 Secondary hyperalgesia; 1.2 Inflation of the central sensitization concept; 1.3 Central sensitivity syndromes. 2 The physiological mechanism; 3 Criteria for the Download Citation | Acute and Chronic Mechanisms of Pain | Pain is [1, 35,37,41,[80][81][82][83]In addition, hyperalgesia and allodynia are av E Öjstedt · 2020 — Allodynia, hyperalgesia, dysesthesia, increased wind-up, regional/general pain distribution and of pain such a complicated issue are the underlying mechanism: The secondary neurons transmitting mechanosensory and.

These lipid mediators in turn act on the terminals of primary afferent nociceptors and lower their threshold for firing. The nociceptors are sensitized. All of this occurs via a peripheral mechanism. Secondary hyperalgesia refers to the sensitization that occurs because of changes in spinal cord processing. 2016-05-11 · Injury-induced secondary hyperalgesia is characterized by reduced thresholds for mechanical stimulation, and is supposed to result from an altered central processing of mechano- and nociceptive input in A-fibers from the periphery, so that activation of these fibers produce painful sensations [ 11 – 14 ].

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. This mechanism also explains the perpetuation of sensitization and thus allodynia. 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.
