PainRelief.com: What are the main findings?
1. Compared to sham control, real electro-acupuncture led to greater pain reduction, but just missed reaching statistical significance (p=0.06).
2. However, compared to sham control, real electro-acupuncture led to statistically and clinically significant improvement in back-related disability (p=0.01).
3. Positive coping-strategies, and non-white race were associated with greater treatment response to real electro-acupuncture.
PainRelief.com: What should readers take away from your report?
1. Electro-acupuncture can lead to clinically and statistically significant improvement in functional impairment related to chronic low back pain. After removing a single outlier, a statistically significant treatment effect in pain reduction is also seen.
2. However, electro-acupuncture does not work for everyone. Individuals who are non-white, and who gravitate toward positive coping strategies, tend to respond better to electro-acupuncture than the rest.
PainRelief.com: What recommendations do you have for future research as a result of this work?
1. To investigate if electro-acupuncture works better than manual acupuncture, a 3-arm study will likely be needed, where patients are randomized to electro-acupuncture, manual acupuncture, and sham control.
2. It would be interesting to see if combing interventions which improve coping strategies can lead to increased response to electro-acupuncture, as suggested by our study.
3. Our study was conducted in Bay Area, it would be important to replicate our findings, particularly the relationship between non-white race and clinical outcome in other areas, where the minority population is not primarily Asian.
