Grading scale to calculate allodynia scores for each animal at each testing session. Two different types of normally innocuous stimuli were used. Animals responsive to the brush stroke test were considered more sensitive and given higher scores than animals responsive to the gentle squeeze test. Vocalization and responses to the finest monofilaments added points to the allodynia score, as they reflect greater sensitivity to touch, as does the aggressiveness of the behavioral response (freezing vs. escape vs. grab/push).
