Pain sensitivity and cardiovascular reactivity to the experimental induced cold pressor pain during different phases of menstrual cycle in young Indian females

Abstract

Response to cold-induced experimental pain in the form of PTh, pain tolerance (PTo), pain rating on visual analogous scale, pulse reactivity (PRe), systolic blood pressure reactivity (SBPRe), and diastolic BPRe (DBPRe).

The parameters used for the response to cold-induced experimental pain were PTh, pain tolerance (PTo), pain rating (PRa) on visual analogous scale, pulse reactivity (PRe), systolic blood pressure reactivity (SBPRe), and diastolic BPRe (DBPRe). [...]it increases the parasympathetic tone and progesterone blocks this action resulting in an increased sympathetic activity during luteal phase.
