The study followed 638 adults with chronic mechanical low back pain who were given one of the following treatments:
- individualized acupuncture (acupuncture treatment formula tailored to the patient)
- standardized acupuncture (typical acupuncture points for lower back pain)
- simulated acupuncture (sham acupuncture using toothpicks on acupuncture points)
- conventional medical treatments of medicine and physiotherapy
Ten treatments were provided over 7 weeks by experienced acupuncturists. The results were as follows:
- By the 8 week mark, all of the acupuncture groups showed an improvement of 4.4 or 4.5 while the conventional medicine group showed an improvement of only 2.1 points.
- By the 8 week mark, the acupuncture groups reported improved symptoms of 1.6 to 1.9 while the conventional medicine group improved symptoms by only 0.7 points.
- By the 1 year mark, the acupuncture groups showed clinically meaningful improvements in dysfunction of 59% to 65% vs the conventional medicine group which showed an improvement of 50%
- In summary, the acupuncture groups showed a larger improvement, greater reduced symptoms and longer lasting improvements than conventional medicine.
- It should also be noted that while the results of sham acupuncture were the same as real acupuncture, sham acupuncture also proved to yield much better results than conventional medicine.
