Exploring home allodynia testing for future clinical and scientific uses

Allodynia, a painful response to a usually nonpainful stimulus, is common in chronic migraine. The evaluation of allodynia can be important clinically. Dynamic mechanical allodynia (brush) testing has been shown to be both a simple and reliable way to evaluate allodynia. In this study, we show that self-administered brush allodynia testing at home is a feasible means of evaluating and recording allodynia in relationship to chronic migraine.
