Tongyuan acupuncture reduces pain, improves sleep quality, and ameliorates emotional comorbidities in patients with postherpetic neuralgia.
In a randomized controlled trial of 106 PHN patients, Tongyuan electroacupuncture significantly reduced SF-MPQ pain scores (VAS, PPI, PRI) and PSQI sleep scores compared to conventional electroacupuncture after 4 weeks. The Tongyuan group had a total effective rate of 90.0% and a pain recurrence rate of 2.2% at 3-month follow-up, versus 74.5% and 17.1% in the control group.

Tongyuan acupuncture reduces pain, improves sleep quality, and ameliorates emotional comorbidities in patients with postherpetic neuralgia. The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 44/100 (low).
The Claim
Tongyuan acupuncture reduces pain, improves sleep quality, and ameliorates emotional comorbidities in patients with postherpetic neuralgia.
This conclusion is most relevant to: Patients with postherpetic neuralgia (PHN), 106 randomized (50 analyzed in Tongyuan group, 47 in control group).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸[Tongyuan acupuncture for postherpetic neuralgia: a randomized controlled trial]. (Zhongguo zhen jiu = Chinese acupuncture & moxibustion, 2026) —
How It Works
The proposed biological pathway:
- ▸Acupuncture at specific acupoints modulates pain signaling pathways
- ▸Electroacupuncture with dense-disperse waves (2/100 Hz) activates descending inhibitory pain controls
- ▸Improved pain relief reduces sleep disturbances and emotional comorbidities
- ▸Result: Reduced pain, improved sleep, and lower anxiety/depression scores
Who Might Benefit
Evidence fit by population:
- ▸Patients with postherpetic neuralgia (PHN), 106 randomized (50 analyzed in Tongyuan group, 47 in control group)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Abstract does not report blinding of participants or practitioners, introducing potential performance bias
- ▸No sham acupuncture control group, so placebo effects cannot be ruled out
- ▸Sample size relatively small (106 randomized, 97 analyzed), limiting generalizability
Frequently Asked Questions
What is Tongyuan acupuncture?▼
Tongyuan acupuncture is a specific acupoint selection protocol used in traditional Chinese medicine, involving points such as Baihui, Yintang, Shuigou, Qihai, Guanyuan, ashi points, and bilateral back-shu points (Xinshu, Geshu, Ganshu, Pishu) and Tianshu, combined with electroacupuncture.
How does Tongyuan acupuncture compare to conventional electroacupuncture for PHN?▼
In this study, Tongyuan acupuncture showed significantly better pain relief (lower SF-MPQ scores), improved sleep quality (lower PSQI scores), reduced anxiety and depression (lower HAMA and HAMD scores), higher total effective rate (90% vs 74.5%), and lower pain recurrence at 3 months (2.2% vs 17.1%).
What outcomes were measured in this study?▼
Outcomes included pain severity (SF-MPQ with PRI, VAS, PPI), sleep quality (PSQI), anxiety (HAMA), depression (HAMD), clinical efficacy rates, and pain recurrence at 3-month follow-up.
Is Tongyuan acupuncture safe for PHN patients?▼
The abstract does not report adverse events, but acupuncture is generally considered safe when performed by trained practitioners. No safety issues were mentioned in this study.
