Evidence-Based Approach
In the realm of healthcare, there is a unanimous consensus that an evidence-based medicine (EBM) framework should serve as the yardstick for evaluating health outcomes. Essential to this approach are systematic reviews conducted with rigorous protocols, publications of which are readily available through organizations like the Cochrane Collaboration and Bandolier. In practical terms, EBM is all about amalgamating individual clinical expertise with the most compelling external evidence, thereby encouraging doctors to consider research that might not conform to the stringent criteria deemed 'top-tier.'
The journey of accumulating an evidential foundation for acupuncture was comprehensively summarized in a review undertaken by researcher Edzard Ernst and a team of colleagues in 2007. They meticulously compared systematic reviews conducted in 2000 and 2005, using similar methodologies:
The effectiveness of acupuncture remains a topic of debate. The findings reveal that the evidence base has expanded for 13 out of 26 conditions that were the subjects of this comparison. For seven of these conditions, the evidence has grown more favorable toward acupuncture, while for the remaining six, it has shown the opposite trend. This leads to the conclusion that acupuncture research is a vibrant and active field. The emerging clinical evidence suggests that acupuncture proves efficacious for some conditions but may not be equally effective for all.
Regarding Low Back Pain, a Cochrane Review from 2005 states:
A systematic review covering 35 randomized controlled trials (RCTs) with a total of 2861 patients was conducted. The review concluded that there is insufficient evidence to formulate recommendations about the use of acupuncture or dry needling for acute low back pain. In the case of chronic low back pain, the results reveal that acupuncture is more effective for pain relief compared to no treatment or sham treatment, especially when assessed over a three-month period. Additionally, for chronic low back pain, acupuncture outperforms no treatment in terms of improving function, particularly in the short term. However, it's important to note that acupuncture doesn't demonstrate superior efficacy to other conventional and "alternative" treatments. When used as a supplementary therapy alongside other conventional approaches, it provides better pain relief and improved function, albeit with relatively modest effects. Dry needling also appears to be a beneficial complement to other treatments for chronic low back pain.
A notable study from 2008 suggests that combining acupuncture with conventional treatments for infertility, such as IVF, can significantly enhance the success rates of these medical interventions.
