To assess the influence of myofascial temporomandibular disorder (TMD) pain on the pressure pain threshold (PPT) of masticatory muscles in women during a migraine attack.
The sample comprised 34 women, 18 to 60 years of age, with a diagnosis of episodic migraine previously confirmed by a neurologist. All subjects were evaluated using the Research Diagnostic Criteria for TMD (RDC/TMD) to determine the presence of myofascial pain. They were divided into two groups: group 1 (n = 18) included women with migraine; group 2 (n = 16) included women with migraine and myofascial TMD pain. Participants were evaluated by measuring PPT values of the masseter and anterior temporalis muscles and Achilles tendon with a pressure algometer at two moments: pain free and during a migraine attack. A three-way analysis of variance with a 5% significance level was used for statistical purposes.
Significantly lower PPT values were found during the migraine attack, especially for women with concomitant myofascial pain, regardless of the side of the reported pain.
Migraine attack is associated with a significant reduction in PPT values of masticatory muscles, which appears to be influenced by the presence of myofascial TMD pain.
评估肌筋膜性颞下颌关节紊乱病（TMD）疼痛对偏头痛发作期间女性咀嚼肌压痛阈（PPT）的影响。
样本包括34名年龄在18至60岁之间的女性，她们之前经神经科医生确诊患有发作性偏头痛。所有受试者均使用颞下颌关节紊乱病研究诊断标准（RDC/TMD）进行评估，以确定是否存在肌筋膜疼痛。她们被分为两组：第1组（n = 18）包括患有偏头痛的女性；第2组（n = 16）包括患有偏头痛和肌筋膜性TMD疼痛的女性。在两个时间段使用压力痛觉计测量咬肌、颞肌前部肌肉和跟腱的PPT值对参与者进行评估：无痛期和偏头痛发作期间。采用显著性水平为5%的三因素方差分析进行统计学处理。
在偏头痛发作期间发现PPT值显著降低，尤其是伴有肌筋膜疼痛的女性，无论所报告疼痛的部位在哪一侧。
偏头痛发作与咀嚼肌PPT值显著降低有关，这似乎受肌筋膜性TMD疼痛的影响。
