Exteroceptive Silent Period of Temporalis Muscle in Menstrual Headaches

Abstract: The second exteroceptive silent period (ES2) of temporalis muscle was recorded on days 1 and 15 of the menstrual cycle in 17 women, 9 of whom suffered regularly from tension-type headaches during menstruation. Mean duration of temporalis ES2 was significantly shorter on day 1 of the cycle than on day 15. This difference was due to a marked menstrual reduction of ES2 in the headache subgroup. A positive correlation was found between ES2 durations and oestradiol/progesterone ratios. We hypothesize that the varia… Show more

“…Analyses pertaining to responses to the cold pressor task (ie, pain threshold and tolerance) failed to show statistically significant group differences, even when covarying the pain‐related anxiety/fear measures. This finding fits within a developing pattern in the literature suggesting that pain perceptions of headache and control participants are likely to differ only when the pain originates from the head 5‐8 . Clearly, future studies examining pain perception differences in patients with headache should carefully consider what appears to be converging evidence and focus their attention on pain perception more specific to headache disorders.…”

“…However, the effect of hormonal change on with neurophysiologic studies of trigeminal system of controls has not been studied extensively so far. Although hormonal changes have been reported to have an indirect influence of brainstem nociceptive modulatory system in tension-type headache, we did not found any significant difference between the perimenstrual and postmenstrual follicular period of healthy volunteers with respect to onset latency of TCR [16]. In our study, these results showed that trigeminal excitability did not change significantly during the different menstrual periods of controls.…”

“…Suppression of the electromyographic activity in contracting temporalis or masseter muscles does not correlate with pain severity, but rather provides evidence of reduced excitability of brain stem inhibitory neurons that affect the trigeminal motor nucleus, through a mechanism mediated by serotonin from the raphe magnus [38]. Schoenen et al [39] recorded the second exteroceptive silent period (ES 2 ) during menses and at midcycle in women who typically experienced tension-type headache with menses, compared to headache-free controls. Significant decreases were seen in the headache group during menses, in association with reductions in estrogen and progesterone.…”
