异常性疼痛
Saline was used in the control group.Mechanical allodynia was determined using the on Frey test. 在腰椎退变患者，突间关节骨赘可能导致神经根压迫，从而诱发神经根病。
RESULTS: Transection of the tibial and sural nerves induced cold allodynia and moderate mechanical hyperalgesia. 结果：胫神经和腓肠神经的横断导致异常性冷疼痛和中等强度的机械性痛觉过敏。
Prevalence and characteristics of allodynia in headache sufferers: a population study. 有多少偏头痛患者有皮肤异常疼痛症状？
Administration of ephrinB2 siRNA reduced the expression of ephrinB2 and mechanical allodynia. ephrinB2siRNA干预可降低ephrinB2的表达和机械性异常疼痛的强度。
However, it appeared that these animals rarely responded with the expected “allodynia” suppression. 由于SNI模型中至少有80%25以上的坐骨神经纤维受损，而且痛觉超敏异常显著，电刺激效果不佳可能与神经损伤的程度过大，使中枢神经系统递质紊乱以及中枢致敏加重有关。
