Pain catastrophizing is related to temporal summation of pain but not temporal summation of the nociceptive flexion reflex.
Pain catastrophizing is associated with enhanced temporal summation of pain (TS-Pain). However, because prior studies have found that pain catastrophizing is not associated with a measure of spinal nociception (nociceptive flexion reflex [NFR] threshold), this association may not result from changes in spinal nociceptive processes. The goal of the present study in healthy participants was to ex...
متن کاملSuppression of first pain and slow temporal summation of second pain in relation to age.
BACKGROUND Thermal stimuli delivered to skin of the arms or legs can produce a sensation of two distinct pains. These pains have been associated with activity in A-delta (first pain) and C-fiber (second pain) nociceptive fibers, respectively. Under appropriate conditions first pain decreases in intensity (adaptation) while second pain increases in intensity (slow temporal summation). Change in ...
متن کاملTemporal summation of trigeminal pain in human anterior cingulate cortex
Temporal summation of nociceptive inputs in trigeminal networks can induce central sensitization and maintain chronic pain. We combined functional magnetic resonance imaging and electrically evoked pain-related potentials (PREP) in healthy human subjects to identify brain regions involved in temporal summation of nociceptive inputs. We stimulated the skin innervated by the ophthalmic division o...
متن کاملRelationships between skin temperature and temporal summation of heat and cold pain.
Temporal summation of heat pain during repetitive stimulation is dependent on C nociceptor activation of central N-methyl-d-aspartate (NMDA) receptor mechanisms. Moderate temporal summation is produced by sequential triangular ramps of stimulation that control skin temperature between heat pulses but do not elicit distinct first and second pain sensations. Dramatic summation of second pain is p...
متن کاملSlow Temporal Summation of Pain for Assessment of Central Pain Sensitivity and Clinical Pain of Fibromyalgia Patients
BACKGROUND In healthy individuals slow temporal summation of pain or wind-up (WU) can be evoked by repetitive heat-pulses at frequencies of ≥.33 Hz. Previous WU studies have used various stimulus frequencies and intensities to characterize central sensitization of human subjects including fibromyalgia (FM) patients. However, many trials demonstrated considerable WU-variability including zero WU...
