Myofascial trigger points are present in dysfunctioning muscles and are associated with several diseases. However, the scientific literature has not established whether myofascial trigger points of differing etiologies have the same clinical characteristics. Thus, the objective of the present study was to compare the intensity of myofascial pain, catastrophizing, and the pressure pain threshold at myofascial trigger points among breast cancer survivors and women with neck pain. This was a cross-sectional study that included women over 18 years old complaining of myofascial pain in the upper trapezius muscle region for more than 90 days, equally divided into breast cancer survivors (n = 30) and those with neck pain (n = 30). For inclusion, the presence of a bilateral, active, and centrally located trigger point with mean distance from C7 to acromion in the upper trapezius was mandatory. The measures of assessment were: pain intensity, catastrophizing, and the pressure pain threshold at the myofascial trigger points. A significant difference was observed only when comparing pain intensity (p < 0.001) between the breast cancer survivors (median score: 8.00 points, first quartile: 7.00 points, third quartile: 8.75 points) and women with neck pain (median score: 2.50 points, first quartile: 2.00 points, third quartile: 4.00 points). No significant difference was found between groups in catastrophizing and pressure pain threshold. The conclusion of this study was that breast cancer survivors have a higher intensity of myofascial pain in the upper trapezius muscle when compared to patients with neck pain, which indicates the need for evaluation and a specific intervention for the myofascial dysfunction of these women.
肌筋膜触发点存在于功能失调的肌肉中，并与多种疾病相关。然而，科学文献尚未确定不同病因的肌筋膜触发点是否具有相同的临床特征。因此，本研究的目的是比较乳腺癌幸存者和颈部疼痛女性在肌筋膜触发点处的肌筋膜疼痛强度、灾难化思维以及压痛阈值。这是一项横断面研究，纳入了18岁以上、抱怨上斜方肌区域肌筋膜疼痛超过90天的女性，她们被平均分为乳腺癌幸存者组（n = 30）和颈部疼痛组（n = 30）。纳入标准要求在上斜方肌中存在双侧、活跃且位于中央的触发点，其从C7到肩峰的平均距离必须符合条件。评估指标包括：疼痛强度、灾难化思维以及肌筋膜触发点处的压痛阈值。仅在比较乳腺癌幸存者（中位数评分：8.00分，第一四分位数：7.00分，第三四分位数：8.75分）和颈部疼痛女性（中位数评分：2.50分，第一四分位数：2.00分，第三四分位数：4.00分）之间的疼痛强度时观察到显著差异（p < 0.001）。两组在灾难化思维和压痛阈值方面未发现显著差异。本研究的结论是，与颈部疼痛患者相比，乳腺癌幸存者在上斜方肌处的肌筋膜疼痛强度更高，这表明需要对这些女性的肌筋膜功能障碍进行评估和特定干预。
