Its clinical manifestations include an exaggerated Secondary hyperalgesia.

Experiment 1: Primary and Secondary Hyperalgesia Testing After Plantar Incision. Before incision, catheterized rats were acclimated to the testing room and testing apparatus (i.e., individual plexiglass compartments measuring 26 × 11 × 20 cm with 12 × 12 mm mesh floors) for 30 min on each of three sequential days.

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). Secondary are hyperalgesias occurring outside such an area.

The area of secondary hyperalgesia is characterised by reduced thresholds for mechanical stimulation, and the size of the area can be quantified by monofilament stimulation. Current evidence indicates that the development of secondary hyperalgesia to punc- 2019-07-18 · Hyperalgesia Increased response to a normally painful stimulus. Primary hyperalgesia Local reduction in pain threshold. Secondary hyperalgesia Hyperalgesia away from the site of injury due to alteration in spinal cord signaling. Allodynia Painful response to a normally painless stimuli. Static hyperalgesia is phenomenologically different from dynamic and punctate allodynia and hyperalgesia produced by chemical irritants such as capsaicin or mustard oil.

Allodynia is a condition in which pain is caused by a stimulus that does not normally elicit pain. For example, bad sunburn can cause temporary allodynia, and touching sunburned skin, or running cold or warm water over it, can be very painful.

We also investigated whether the degree of analgesia was related to baseline conditioned pain modulation (CPM) responses. Methods: Nineteen subjects had baseline CPM and electrical pain perception (EPP) thresholds measured before the topical application of capsaicin cream. Visual analogue scale ratings were Spread of hyperalgesia is likely due to central sensitization of nociceptive neurons in the spinal cord by primary nociceptive afferent input (neurogenic hyperalgesia), which is the basis of secondary hyperalgesia in the vicinity of any site of injury. 77 Baumgärtner U, Magerl W, Klein T, Hopf HC, Treede RD. Static hyperalgesia is phenomenologically different from dynamic and punctate allodynia and hyperalgesia produced by chemical irritants such as capsaicin or mustard oil.

This type of hyperalgesia is when the increased pain occurs in the tissue where the injury took Secondary hyperalgesia. This type occurs when the pain seems to spread to non-injured tissue or tissues. Other types of hyperalgesia. Another kind of hyperalgesia is Secondary hyperalgesia is inducible in most individuals and is attributed to central neuronal sensitization. Some individuals develop large areas of secondary hyperalgesia (high-sensitization responders), while others develop small areas (low-sensitization responders). Heat pain thresholds inside the secondary mechanical hyperalgesic zone were not significantly different from thresholds outside the secondary mechanical hyperalgesia zone.
