Abstract：
BACKGROUND: MPS is a chronic disorder caused by myofascial trigger points, leading to pain and limited neck movements due to impacted fascia. Studies have reported reduced fascia slides in chronic low back pain, but limited fascia slides in MPS patients are still unreported.
OBJECTIVE: We determined differences in upper trapezius\' deep fascia slides between MPS and non-MPS participants.
METHODS: Between January-August 2019, participants from diverse work sectors were recruited in Manila. An expert physiotherapist diagnosed MPS, while non-MPS participants performed full painless cervical movements. Participants underwent upper trapezius deep fascia scans on both shoulders while performing six cervical movements. An HS1 Konica Minolta ultrasound recorded the data. Two blinded physiotherapists used Tracker 5.0 © 2018 to analyze videos and quantify deep fascia slides by measuring the distance between two x-axis points. The Multivariate analysis of variance (MANOVA) assessed deep fascia slide differences in six active cervical movements. Pillai\'s Trace, with a range of 0-1 and a p-value of <0.05, was set. Effect sizes in individuals with and without MPS were calculated using Hedges\' g and Cohen\'s d.
RESULTS: Of the 327 participants (136 non-MPS, 191 MPS), 101 MPS participants had shoulder pain for <1 year and 103 experienced unilateral pain. The study examined 3800 ultrasound videos but found no significant difference in deep fascia slides across cervical movements between MPS and non-MPS groups (Pillai\'s Trace = 0.004, p = 0.94). Minor differences in deep fascia displacement were observed, with small effect sizes (g = 0.02-0.08).
CONCLUSIONS: A limited deep fascia slide does not characterize MPS participants from non-MPS participants.

摘要：
背景：MPS是由肌筋膜触发点引起的慢性疾病，由于筋膜受累导致疼痛和颈部活动受限。有研究报告说，在慢性下背痛中，筋膜滑动减少，但仍未报道MPS患者的有限筋膜载玻片。
目的：我们确定了MPS和非MPS参与者的上斜方肌深筋膜片的差异。
方法：在2019年1月至8月之间，马尼拉招募了来自不同工作部门的参与者。一位专家物理治疗师诊断为MPS，而非MPS参与者进行了完全无痛的颈椎运动。参与者在进行六个颈椎运动的同时，在两个肩膀上进行了上斜方肌深筋膜扫描。HS1柯尼卡美能达超声记录了数据。两名盲人物理治疗师使用Tracker5.0©2018分析视频并通过测量两个x轴点之间的距离来量化深筋膜幻灯片。多变量方差分析（MANOVA）评估了六种活跃颈椎运动的深筋膜滑动差异。皮莱的踪迹,范围为0-1，p值<0.05。使用Hedges\'g和Cohen\'sd计算有和没有MPS的个体的效应大小。
结果：在327名参与者中（136名非MPS，191MPS)，101名MPS参与者肩痛<1年，103名患者单侧疼痛。该研究检查了3800个超声视频，但发现MPS组和非MPS组之间在颈椎运动中的深筋膜滑动没有显着差异（Pillai\'sTrace=0.004，p=0.94）。观察到深筋膜位移的微小差异，小效应尺寸（g=0.02-0.08）。
结论：有限的深筋膜滑动不能表征非MPS参与者的MPS参与者。
