Key Finding
After six weeks of twice-weekly electroacupuncture, a statistically significant proportion of ankylosing spondylitis patients achieved at least a 30% reduction in pain severity scores despite inadequate relief from conventional analgesia (p = 0.002).
Living with ankylosing spondylitis (AS) means dealing with chronic inflammatory back pain that can significantly limit daily life. For many patients, standard pain medications simply don't provide enough relief. Researchers in Hong Kong wanted to explore whether electroacupuncture — a form of acupuncture that uses gentle electrical stimulation through the needles — could help fill that gap.
In this pilot study, 20 people with AS who were still experiencing moderate to severe pain despite taking their usual medications received electroacupuncture twice a week for six to ten weeks. Researchers tracked not just pain levels, but also physical function, disease activity, joint swelling, and overall quality of life.
The results were encouraging. After just six weeks of treatment, a statistically significant number of participants experienced at least a 30% reduction in their pain scores — a meaningful improvement for people who had not found adequate relief through conventional treatment alone. Improvements were also seen in physical function and overall wellbeing measures.
It's important to note that this was a small pilot study without a comparison group, meaning the researchers cannot yet say with certainty that electroacupuncture alone caused the improvements. A larger, randomized controlled trial is needed to confirm these findings. That said, the study demonstrates that electroacupuncture is a feasible and potentially valuable option for AS patients whose pain remains poorly controlled.
For AS sufferers who feel like they've exhausted their options, this research offers a reason for cautious optimism. Electroacupuncture may one day become a recognized part of an integrated pain management plan for inflammatory back conditions.
If you are considering electroacupuncture for ankylosing spondylitis or chronic back pain, speak with your rheumatologist and seek treatment from a licensed, qualified acupuncture practitioner with experience managing inflammatory conditions.
This single-arm pilot study (NCT02697968) evaluated the feasibility of semi-standardized electroacupuncture (EA) as an adjunct intervention for ankylosing spondylitis (AS) patients with suboptimally controlled pain despite conventional analgesia. Twenty AS patients with moderate-to-severe pain were recruited in Hong Kong; 18 completed the protocol. EA was administered twice weekly for 6–10 weeks, with outcome assessments at baseline and weeks 6, 10, and 18.
The primary feasibility endpoint — ≥10% of subjects achieving ≥30% reduction in pain NRS at week 6 — was met with statistical significance (one-sided exact binomial test, p = 0.002). Secondary outcomes including BASFI, BASDAI, BASGI, SF-36, and inflammatory markers (CRP, ESR) were also monitored.
Clinical takeaway: EA appears feasible and potentially effective as adjunct pain management in AS. The semi-standardized protocol and multi-domain outcome battery provide a replicable framework. A adequately powered RCT is warranted to establish efficacy and inform clinical integration.

📌 Acupuncture at GB34, ST36, and ST35 significantly reduced knee cartilage degeneration and systemic inflammation in KOA rats by inhibiting the PI3K/Akt/mTOR signaling pathway and restoring chondrocyte autophagy, with combined acupuncture and exercise therapy producing superior results over either treatment alone.
📌 Modified acupuncture techniques, including electroacupuncture and needle-knife therapy, significantly reduced TNF-α levels in knee osteoarthritis patients compared to traditional acupuncture (SMD = -1.63, p < 0.01), with moderate GRADE evidence supporting this effect.
