Key Finding
Chronic low back pain patients who perceived themselves as sensitive to medicines were significantly more likely to report side effects from acupuncture treatment (r=0.24, p<0.01).
Researchers examined whether people who believe they are sensitive to medicines are more likely to report side effects from acupuncture treatment. The study involved 152 adults with chronic low back pain (pain lasting more than three months) who received acupuncture as part of a clinical trial. Participants answered questions about their perceived sensitivity to medicines, any side effects they experienced, and various personal factors like anxiety, depression, and their expectations about treatment. The researchers found that patients who believed they were sensitive to medicines were indeed more likely to report side effects from acupuncture. They also found that these individuals tended to have higher anxiety levels. Interestingly, anxiety didn't directly explain the link between medicine sensitivity and side effects, suggesting the relationship is more complex. This is important because side effects can lead patients to stop treatment early, even when it might be helping. The findings suggest that acupuncturists should talk with patients about any concerns regarding sensitivity to treatments and address anxiety before starting care. Understanding a patient's beliefs about their sensitivity to medicines may help practitioners anticipate potential side effects and develop strategies to minimize them. This personalized approach could improve treatment outcomes and help patients stay committed to their care plan. If you're considering acupuncture for chronic pain, seek a licensed or certified acupuncturist who will take time to discuss your concerns and treatment expectations.
This secondary analysis of an RCT examined the relationship between perceived sensitivity to medicines (PSM) and reported side effects in chronic low back pain patients receiving acupuncture (n=152, mean age 39.5 years, 65.8% female). Using correlational and regression analyses of self-reported measures, researchers found a significant positive correlation between PSM and reported side effects (r=0.24, p<0.01) and between PSM and anxiety (r=0.21, p<0.05). However, regression analyses did not confirm anxiety as a mediating or moderating variable in the PSM-side effect relationship. This study extends PSM research to nonpharmacological interventions in a specific pain population. Clinical implications include the importance of assessing patient PSM and anxiety levels during intake, as these factors may predict side effect reporting. Practitioners should consider pre-treatment counseling addressing patient beliefs about treatment sensitivity and anxiety management strategies to potentially reduce nocebo effects and improve treatment adherence.
