Dynamic mechanical allodynia in the secondary hyperalgesic area in the capsaicin model-Perceptually similar phenomena as in painful neuropathy?

► Only 3/9 controls but 8/9 patients had tactile allodynia after capsaicin injection. ► Similar brush-evoked pain intensity in patients' area of neuropathy and capsaicin. ► Low frequency of tactile allodynia makes the capsaicin model a tedious procedure.
