目的：通过使用假调整来确定安慰剂整脊治疗的各个方面，这些调整可能会导致治疗效果并可能影响盲法的成功。设计与情境：在一所脊椎指压学院研究型诊所进行两期交叉设计。研究对象：18名在过去6个月内报告腰痛的脊椎按摩学院的志愿者、学生和教职员工。干预措施：采用屈曲-牵张技术进行捏脊调整，并使用手持式仪器（激活器调整仪）将压力表设置在9上进行假调整。治疗期2周，共4次就诊。主要结果测量：疼痛的视觉模拟量表（VAS）和全球幸福量表（GWBS）。结果：虽然VAS和GWBS评分在两种治疗中都有所改善，但在大多数情况下，积极治疗的改善程度更大。接受采访的14名患者中有8人认为安慰剂有治疗效果。结论：本研究提供了初步信息，有助于在设计的随机临床试验中规划安慰剂捏脊治疗方案。
Objective: To identify aspects of the delivery of placebo chiropractic treatments by using sham adjustments that may cause a treatment effect and that may affect the success of blinding.Design and Setting: Two-period crossover design in a chiropractic college research clinic.Subjects: Eighteen volunteer staff, students, and faculty of the chiropractic college who reported low-back pain within the last 6 months.Interventions: Flexion-distraction technique was used to perform chiropractic adjustments, and a hand-held instrument (Activator adjusting instrument) with the pressure gauge set on the 9 was used to perform sham adjustments. The treatment period was 2 weeks, with a total of 4 visits.Main Outcome Measures: The Visual Analog Scale (VAS) for pain and Global Well-Being Scale (GWBS).Results: Although VAS and GWBS scores improved with both treatments, a somewhat greater improvement occurred in most cases with the active treatment. Eight of 14 patients interviewed believed that the placebo had a treatment effect.Conclusion: This study provided preliminary information that was useful in planning the protocol for a placebo chiropractic treatment in the randomized clinical trial for which it was designed.
