Central sensitization is implicated in fibromy 2015-01-23 · 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). Temporomandibular disorder (TMD) is commonly comorbid with fibromyalgia syndrome (FMS). The incidence of these pain conditions is prevalent in women and prone to mental stress. Chronic pain symptoms in patients with FMS and myofascial TMD (mTMD) are severe and debilitating. In the present study, we developed a new animal model to mimic the comorbidity of TMD and FMS.

Secondary hyperalgesia was induced by intradermal injection of 40 μg capsaicin, and pain sensitivity in adjacent skin was tested with 200 μm diameter probes (35-407 mN). The progress of conduction blockade was monitored by touch, cold, warm and first pain detection and by compound sensory nerve action potential. 2021-03-19 · Sex-dependent Cav2.3 channel contribution to the secondary hyperalgesia in a mice model of central sensitization.

When central sensitization and referred pain co-occur, secondary hyperalgesia may take a different form: silent nociceptors can mediate new regions of cutaneous or deep muscle hypersensitivity (64 These early QST studies typically noted the same findings of secondary hyperalgesia or allodynia seen in animal models of central sensitization, and this was used to infer that these same underlying processes may be playing a role in humans with these chronic pain conditions. Lack of secondary hyperalgesia and central sensitization in an acute sheep model. Mather LE(1), Cousins MJ, Huang YF, Pryor ME, Barratt SM. Author information: (1)Department of Anaesthesia and Pain Management, University of Sydney at Royal North Shore Hospital, St Leonards, NSW, Australia. lmather@med.usyd.edu.au Secondary hyperalgesia is due to central neuron sensitization and requires continuous nociceptor input from the zone of primary hyperalgesia for its maintenance. Secondary hyperalgesia implies only mechanical hyperalgesia, i.e. “allodynia“ and “pin prick“. Thermal hyperalgesia does not occur in … Conclusions When subjects are observed across days, 'central sensitization', measured as the area of secondary hyperalgesia after a first-degree burn, does not seem to be important for clinical pain intensity per se, but may be important for clinical pain variation.
