Mechanical allodynia

In 12 zoster patients who had developed postherpetic neuralgia with dynamic mechanical allodynia and in six zoster patients who had recovered without pain, the functional role of nociceptive C-fibers in allodynia was assessed by quantifying axon reflex reactions induced by histamine iontophoresis ...

Mechanical allodynia (pain) can result from innocuous stimuli such as light touch (Lolignier, Eijkelkamp, & Wood, 2015). Since mechanical allodynia is associated with the cAMP messenger pathway mediated by the protein EPAC1, the connection between Piezo2 and this pathway was examined (Eijkelkamp, Linley, et al., 2013). A neuropathic pain model ...

Because allodynia is an evoked pain, testing requires an external stimulation of non-painful quality. Mainly three different types of stimulation have been used to test allodynia in animal models of neuropathic pain: mechanical touch, cold, and air blow. Allodynia is the experience of pain from a non-painful stimulation of the skin, such as light touch. The type of migraine, the frequency and severity of attacks, and the number of years of the headache disorder relate to the presence and severity of allodynia. Mechanical allodynia (other pain) is a painful sensation caused by innocuous stimuli like light touch. Unlike inflammatory hyperalgesia that has a protective role, allodynia has no obvious ...

Prevalence estimates of allodynia in migraine patients range from 50–80% (Lovati et al., 2009). Three distinct forms of allodynia have been described: thermal, static mechanical, and dynamic mechanical allodynia (Young et al., 2005). Furthermore, a distinction between cranial and extra-cranial allodynia can be made. Dec 12, 2017 · the rainbow pain scale: this also used standardized pressure stimuli to determine the severity of mechanical allodynia; I found 48 records describing patients referred for treatment who demonstrated allodynia accompanying CRPS. 70% were female, and the average age was 45 years. The average area of allodynia was 66 cm 2 or about 10 square inches ... Sometimes, allodynia may be set off by a trigger, such as scratching or stepping on something sharp. Allodynia comes in two forms: mechanical allodynia, associated with physical stimuli, and thermal allodynia, triggered by changes in temperature. Allodynia definition is - pain resulting from a stimulus (such as a light touch of the skin) which would not normally provoke pain; also : a condition marked by such pain.
