Key Finding
Acupuncture probably provides a small improvement in function compared to sham acupuncture and a medium reduction in pain intensity compared to no treatment for adults with chronic low back pain.
Low back pain affects millions of people and can significantly impact daily life. Researchers analyzed 31 comprehensive reviews covering 644 studies with over 97,000 adults to understand which non-drug, non-surgical treatments work best for low back pain.
For people with chronic low back pain, acupuncture showed promising results. When compared to sham (fake) acupuncture, real acupuncture probably provides a small improvement in physical function. When compared to no treatment at all, acupuncture probably reduces pain intensity by a moderate amount and improves function slightly. When compared to usual medical care, acupuncture probably provides a small improvement in function.
Other treatments that showed benefit for chronic low back pain included exercise therapy, which probably reduces pain and improves function when compared to no treatment or usual care. Multidisciplinary therapies (combining multiple approaches) and certain psychological therapies also probably help reduce pain intensity.
For acute or recent low back pain, the evidence for acupuncture was not specifically examined in this overview. However, advice to stay active (rather than rest) and spinal manipulation showed some benefits.
Safety data was limited, but available evidence suggests acupuncture may have similar rates of adverse events compared to sham acupuncture, though more research is needed on safety outcomes across all treatments.
If you're considering acupuncture for low back pain, seek care from a licensed acupuncturist who has appropriate training and credentials in your jurisdiction.
This overview of 31 Cochrane reviews encompassing 644 RCTs (n=97,183 adults) evaluated non-pharmacological interventions for LBP using GRADE methodology. For chronic LBP, acupuncture versus sham showed probable small functional improvement (SMD -0.38, 95% CI -0.69 to -0.07; 3 trials, 957 participants; moderate-certainty evidence). Versus no treatment, acupuncture demonstrated probable medium pain reduction (MD -10.1, 95% CI -16.8 to -3.4; 3 trials, 144 participants) and small functional improvement (SMD -0.39, 95% CI -0.72 to -0.06). Versus usual care, functional improvement was probable (MD 9.4, 95% CI 6.15 to 12.65; 1 trial, 734 participants). Safety profiles appeared comparable to sham (RR 0.68, 95% CI 0.42 to 1.10; 4 trials, 465 participants; low-certainty evidence). Exercise therapy and multidisciplinary approaches also demonstrated moderate-certainty evidence for pain and functional improvements. Clinical takeaway: Acupuncture represents an evidence-based adjunct for chronic LBP management with probable benefits for pain and function.
