Key result
Nociceptive flexion reflex responses were significantly attenuated during systole compared to diastole, supporting the arterial baroreflex mechanism of hypertensive hypoalgesia.

Extends baroreflex hypoalgesia evidence to normotensives; leaves open clinical relevance for hypertension or pain interventions.
Does arterial baroreceptor stimulation during systole reduce nociceptive flexion reflex in normotensive adults?
Natural changes in blood pressure during the cardiac cycle dampen nociception, supporting the arterial baroreflex mechanism of hypertensive hypoalgesia.
Edwards et al. (2001) studied this question. Systole (maximal arterial baroreceptor stimulation) vs. Diastole (minimal stimulation) was evaluated on Nociceptive flexion reflex (NFR) indexed by electromyographic (EMG) activity. Nociceptive flexion reflex responses were significantly attenuated during systole compared to diastole, supporting the arterial baroreflex mechanism of hypertensive hypoalgesia.
