TJ Coderre, ME Fundytus, JE McKenna, S Dalal… - Pain, 1993 - Elsevier
The formalin test was developed using an ordinal scale of weighted scores to rate the
intensity of pain-related behaviours in animals. However, no studies have been carried out
to establish the ordinal relationship of the behavioural categories used to generate the
weighted pain intensity scores. The purpose of the present study was to evaluate the validity
of the weighted-scores technique by assessing the ordinality of the behavioural categories
associated with the specific category weights. The amount of time spent in each of 4 …
