: Pelvic floor muscles (PFM) play a vital role in the proper functioning of the pelvic and abdominal organs. The PFM are structurally connected to other areas of the body, forming part of the deep front line. Due to its course, this line connects the PFM with the temporomandibular joint (TMJ). The aim of the study was to evaluate the impact of a single 15-minute soft tissue therapy session in the TMJ on the activity of the PFM. : A total of 47 nulliparous women aged 20-29 years old diagnosed with myofascial pain in the TMJ area were included in the study. PFM were assessed using the Noraxon Ultium device and a vaginal probe, utilizing the surface electromyography (sEMG) method. The sEMG signal was processed with MyoResearch XP software version 1.0. Additionally, bladder floor displacement during PFM contractions was evaluated using an ultrasound imaging device set in B-mode (LOGIQ P7/P9). : In the experimental group, following the applied soft tissue therapy, a significant decrease in resting PFM activity between maximal contractions was observed ( < 0.05). The resting PFM activity assessed in the final phase of the measurement protocol was also significantly lower ( < 0.05). During endurance contractions in the experimental group, after the therapy, an 18.05% increase in PFM tension amplitude was noted, although this change was not statistically significant. In the control group, a decrease in amplitude was observed during the second assessment in this phase of the test. : A single session of soft tissue therapy in the TMJ area may enhance the ability of the pelvic floor muscles to relax and contribute to improved muscle function by increasing their activation levels during submaximal contractions.
盆底肌（PFM）在盆腔和腹部器官的正常功能中起着至关重要的作用。盆底肌在结构上与身体的其他部位相连，构成了深前线的一部分。由于其走行，这条线将盆底肌与颞下颌关节（TMJ）相连。本研究的目的是评估在颞下颌关节进行单次15分钟软组织治疗对盆底肌活动的影响。
共有47名年龄在20 - 29岁、诊断为颞下颌关节区域肌筋膜疼痛的未生育女性纳入本研究。使用Noraxon Ultium设备和阴道探头，采用表面肌电图（sEMG）方法评估盆底肌。sEMG信号用MyoResearch XP软件版本1.0进行处理。此外，使用设置为B模式的超声成像设备（LOGIQ P7/P9）评估盆底肌收缩时膀胱底部的位移。
在实验组中，进行软组织治疗后，观察到最大收缩之间的盆底肌静息活动显著降低（<0.05）。在测量方案的最后阶段评估的盆底肌静息活动也显著降低（<0.05）。在实验组的耐力收缩过程中，治疗后盆底肌张力幅度增加了18.05%，尽管这一变化无统计学意义。在对照组中，在该测试阶段的第二次评估期间观察到幅度下降。
在颞下颌关节区域进行单次软组织治疗可能会增强盆底肌的放松能力，并通过在次最大收缩期间提高其激活水平来改善肌肉功能。
