There are some very indepth studies going on around the world that are provingthe effectiveness of acupuncture.
The article below explains.
“For chronic pain, in the largest study of its kind to date, 454,920 patients were treated with acupuncture for headache, low back pain, and/or osteoarthritis in an open pragmatic trial. Effectiveness was rated as marked or moderate in 76% of cases by the 8,727 treating physicians.19 In a 2-year retroactive survey of over 89,000 patients published in 2016, 93% of patients said that their acupuncturist had been successful in treating their musculoskeletal pain.20
A meta-analysis of 17,922 patients from randomized trials concluded, “Acupuncture is effective for the treatment of chronic pain and is therefore a reasonable referral option. Significant differences between true and sham acupuncture indicate that acupuncture is more than a placebo.”21 A follow up study with this data looking at long-term pain relief, found that the benefits of acupuncture persisted 12 months after treatment ended.22
