On the McGill Pain Questionnaire, the words frequently used by the participants to describe their pain during labour were: cramping, aching, and tearing (from the sensory aspect), and tiring/exhausting (from the affective aspect). The range of words used to describe the pain was similar in both groups, before and after the procedure. There were no statistically significant differences between the groups in terms of the number of words chosen, the estimated pain index, or present pain intensity. These data are presented in Table 2, with individual patient data presented in Table 3 (on the eAddenda.)
