Podcast episode (host Dr. Jeff Langmaid) reviewing a secondary analysis of a randomized clinical trial on cervical spinal manipulation in ~60 chronic neck-pain patients. The study compared real vs sham adjustments while experimentally manipulating clinician messaging (positive, neutral, negative), measured salivary cortisol and patient fear, and used regression to estimate contributions to immediate pain relief. Key takeaways: positive expectations explained the largest share of variance in short-term pain relief (>50%), real adjustments contributed ~20–25%, while cortisol changes and fear were not significant predictors; practical advice centers on deliberately using positive, expectation-setting language throughout the patient experience.
