Key Finding
Acupuncture, particularly as adjunct therapy, significantly reduced pain, morning stiffness, and key inflammatory markers including CRP, ESR, and pro-inflammatory cytokines in patients with ankylosing spondylitis across 52 randomized controlled trials.
Ankylosing spondylitis (AS) is a chronic inflammatory condition that causes pain and stiffness in the spine, sacroiliac joints, and surrounding tissues. Living with AS can be exhausting, and many patients look beyond conventional medication for relief. A new large-scale review published in Frontiers in Neurology suggests that acupuncture may offer meaningful help.
Researchers analyzed 52 randomized controlled trials — the gold standard of medical research — examining how acupuncture affected people with AS. They looked at pain levels, morning stiffness, physical function, and blood markers of inflammation.
The results were encouraging. Patients who received acupuncture, either alone or alongside their regular medications, reported significantly less pain. Morning stiffness — that frustrating rigidity many AS patients feel upon waking — was noticeably shorter in duration. Blood tests also showed reductions in key inflammation markers, including C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), both of which signal how actively the immune system is inflamed.
Beyond pain and stiffness, researchers found improvements in disease activity scores (BASDAI) and physical function scores (BASFI), which measure how much AS affects daily life. Immune system chemicals that drive inflammation — including IL-6, IL-17, and TNF-alpha — were also reduced, suggesting acupuncture may work partly by calming an overactive immune response.
The researchers noted that acupuncture appeared most effective when used as an add-on to conventional treatment rather than as a standalone therapy. While the results are promising, the studies varied in design and quality, so more rigorous research is still needed.
For AS patients curious about acupuncture, this review adds meaningful support to the conversation with your rheumatologist. To get started safely, seek a licensed, board-certified acupuncturist with experience treating inflammatory and autoimmune conditions.
This systematic review and meta-analysis (52 RCTs) examined acupuncture's effect on clinical symptoms and immune parameters in ankylosing spondylitis (AS). Twenty studies demonstrated low risk of bias per Cochrane RoB 2 and GRADE assessment. Meta-analysis using Stata 15.0 revealed statistically significant reductions in pain (VAS: MD = -1.26, 95% CI [-1.44, -1.09]), CRP (MD = -3.49, [-4.12, -2.85]), ESR (MD = -5.36, [-6.82, -3.89]), and morning stiffness duration (MD = -1.32, [-1.87, -0.78]). Significant improvements were observed in BASDAI, BASFI, and pro-inflammatory cytokines including IL-1, IL-6, IL-17, TNF-α, and IgA. Heterogeneity was moderate to high (I² = 59.70–90.00%), with subgroup analyses attributing variance to intervention design and treatment duration. No significant publication bias was detected for primary outcomes. Sensitivity analyses confirmed robustness of inflammatory marker findings. Clinically, acupuncture as adjunct therapy demonstrates the strongest evidence profile for symptom management and immunomodulation in AS, though heterogeneity warrants cautious extrapolation to individual treatment protocols.

📌 The Bushen Tongdu external treatment combining full-channel moxibustion and acupoint catgut embedding achieved a 90.6% effective rate in kidney-yang deficiency type ankylosing spondylitis, significantly outperforming salazosulfapyridine on BASDAI scores and serum inflammatory markers IL-6, TNF-α, and MMP-3.
📌 A six-week course of electroacupuncture produced a clinically meaningful reduction in WOMAC global scores compared to sham acupuncture (MD: 40.56; Cohen's d=1.21), with exploratory MRI data suggesting possible anti-inflammatory and cartilage-protective structural effects.
