The purpose of this study was to evaluate the pain/pressure threshold of selected myofascial points in subjects with chronic mechanical back pain after a single manipulation or mobilization.
The study design was a randomized control trial.
Chiropractic College outpatient clinic.
Thirty subjects aged 18-50 yr (mean age 31 yr, SD = 7 yr) with chronic mechanical low back pain (mean duration of pain 74 months, SD = 83 months) were randomized into two groups. One group received a manipulation and the other received a mobilization.
Pain/pressure threshold of selected myofascial points were measured before, immediately after, and 15 and 30 min postintervention.
Sixteen patients were allocated to the manipulation group and 14 to the mobilization group. Repeated measured analysis of variance for all locations failed to show clinical or statistical significance (p > .287). The overall effect between treatments and the interaction between treatment and time was not significant (p > .268).
The absence of significant changes may be attributed to the selection of myofascial points, the instrument sensitivity to small changes, the differences in baseline measures and the absence of effect from one intervention.
本研究旨在评估单次手法治疗或松动治疗后，慢性机械性背痛患者所选肌筋膜点的疼痛/压力阈值。
本研究设计为随机对照试验。
脊骨神经医学院门诊诊所。
30名年龄在18 - 50岁（平均年龄31岁，标准差 = 7岁）的慢性机械性下背痛患者（平均疼痛持续时间74个月，标准差 = 83个月）被随机分为两组。一组接受手法治疗，另一组接受松动治疗。
在干预前、干预后即刻、干预后15分钟和30分钟测量所选肌筋膜点的疼痛/压力阈值。
16名患者被分配到手法治疗组，14名患者被分配到松动治疗组。对所有部位进行重复测量方差分析，未显示出临床或统计学意义（p > 0.287）。治疗之间的总体效应以及治疗与时间之间的交互作用均无显著性差异（p > 0.268）。
未出现显著变化可能归因于肌筋膜点的选择、仪器对微小变化的敏感性、基线测量的差异以及一种干预措施无效果。
