Defining the nociceptive flexion reflex (NFR) threshold in human participants: a comparison of different scoring criteria.
Despite the widespread use of the nociceptive flexion reflex (NFR) paradigm in clinical and experimental pain research, there is currently no consensus on how best to define NFR threshold. Accordingly, the present studies were designed to assess the accuracy and reliability of different NFR threshold scoring criteria. Study 1 compared 13 scoring criteria in their accuracy for identifying the pr...
متن کاملUsing normalized EMG to define the nociceptive flexion reflex (NFR) threshold: further evaluation of standardized NFR scoring criteria.
The nociceptive flexion reflex (NFR) has been used as a psychophysiological tool to study spinal nociceptive processes in numerous clinical and experimental studies. Despite widespread use of the NFR, few attempts have been made to empirically test and compare different scoring criteria to detect the presence/absence of the reflex. The present studies were conducted to address this issue. Study...
متن کاملReliability and validity of a brief method to assess nociceptive flexion reflex (NFR) threshold.
UNLABELLED The nociceptive flexion reflex (NFR) is a physiological tool to study spinal nociception. However, NFR assessment can take several minutes and expose participants to repeated suprathreshold stimulations. The 4 studies reported here assessed the reliability and validity of a brief method to assess NFR threshold that uses a single ascending series of stimulations (Peak 1 NFR), by compa...

متن کاملEndogenous inhibition of the nociceptive flexion reflex (NFR) and pain ratings during the menstrual cycle in healthy women.
BACKGROUND The menstrual cycle influences pain, with symptoms often increasing during the premenstrual (late-luteal) phase. Deficiencies in endogenous inhibition of afferent nociception at the spinal level might contribute to menstrual phase-related changes in pain. PURPOSE This study assessed whether conditioned pain modulation (CPM) of spinal nociception differs between mid-follicular and l...
