Evidences for Acupuncture

What is Evidence-Based Practice (or Evidence-Based Medicine)?

As an instructor for Evidence-Based Practice (EBP) course at National University, Dr. Wang has been constantly collect the most advanced evidences for acupuncture and share with his students.

The most common definition of Evidence-Based Practice  is from Dr. David Sackett (1996):  “The conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient.”

The evidence, by itself, does not make the decision, but it can help support the patient care process and enhances the opportunity for optimal clinical outcomes and quality of life.

1.  How does acupuncture relieve pains?

Scholars from Duke University Medical Center searched the databases of Medline from 1966 to 2007 and concluded “Perioperative acupuncture may be a useful adjunct for acute postoperative pain management.”Postoperative pain intensity was also significantly decreased in the acupuncture group compared with the control group. The acupuncture treatment group was associated with a lower incidence of opioid-related side-effects such as nausea, dizziness, sedation, pruritus and urinary retention.

2.  Does acupuncture help Infertility? 

Research (57 infertile patients undergoing IVF or IVF) from University of Pittsburgh, Magee-Womens Hospital indicated patients pregnancy with acupuncture  64.7%,  without acupuncture 42.5%.

The acupuncture regimen was associated with less stress both before and after embryo transfer, and it possibly improved pregnancy rates. Lower perceived stress at the time of embryo transfer may play a role in an improved pregnancy rate. For details please visit  PubMed or PDF.

 

Review: Clinical Research into Acupuncture and Fertility

 The following is a conclusion from a review  that have summarized the role of acupuncture in fertility:
“Acupuncture has been used to treat infertility extensively, including ovulatory dysfunction, in vitro fertilization and embryo transfer (IVF-ET), and male infertility.  This review summarizes the recent studies which investigated the role of acupuncture in infertility.  In conclusion, most of the existing studies suggest a positive effect of acupuncture in infertility treatment.  Firstly, acupuncture may improve ovulation by modulating the central and peripheral nervous systems, the neuroendocrine and endocrine systems, the ovarian blood flow, and metabolism.  Secondly, acupuncture can improve the outcome of IVF-ET, and the mechanisms may be related to the increased uterine blood flow, inhibited uterine motility, and the anesis of depression, anxiety and stress.  Its effect on modulating the immune function also suggest helpfulness in improving the outcome of IVF-ET. Finally, the studies suggest that acupuncture plays a positive role in male infertility, the mechanism of which is not yet clear.  Even though a positive effect of acupuncture in infertility has been found, well-designed multi-centre, prospective randomized controlled studies are still needed to provide more reliable and valid scientific evidence. Furthermore, it is urgent and necessary to clarify the mechanism of acupuncture for infertility.”  (Huang et al, 2011)

3. Does Acupuncture help post-operation Lymphoedema ?

Clinical Trial from Memorial Sloan-Kettering Cancer Center indicated Acupuncture for breast cancer related lymphedema appears safe and may reduce arm circumference. “Although these results await confirmation in a randomized trial, acupuncture can be considered for women with no other options for sustained arm circumference reduction.”   (For more information please visit PubMed3, or PDF)

A study from Japan indicated that  acupuncture is also helpful for Patients of carcinoma of the uterine cervix and body, or for ovarian cancer undergoing intrapelvic lymph node dissection.  (PDF for this article)
