Contribution of afferent pathways to nerve injury-induced spontaneous pain and evoked hypersensitivity.

King T, Qu C, Okun A, Mercado R, Ren J, Brion T, Lai J, Porreca F (2011) Contribution of afferent pathways to nerve injury-induced spontaneous pain and evoked hypersensitivity. Pain 152(9):1997-2005. doi: 10.1016/j.pain.2011.04.020

Summary: Whether exaggerated pain response to a normally innocuous tactile stimulus should be defined as allodynia has been debated. Through the use of several techniques, one of which was intrathecal injection of SSP-SAP (Cat. #IT-11, 16.5 pg), the authors examined which pathways were utilized in this type of pain. Blank-SAP (Cat. #IT-21) was used as a control. The data indicate that tactile stimulation may reflect a different pain state than allodynia.
