Dose-effect of long-snake-like moxibustion for chronic fatigue syndrome: a randomized controlled trial.
Luo, Hong, Gong, Rui, Zheng, Rui et al. · Journal of translational medicine · 2023 · DOI
Quick Summary
This study tested whether longer sessions of moxibustion (a traditional Chinese medicine heat treatment) might work better than shorter sessions for chronic fatigue syndrome. Sixty women with CFS were treated either 60 minutes or 30 minutes per session, three times per week for four weeks. The 60-minute sessions produced greater improvements in fatigue and other symptoms, and thermal imaging showed better changes in body heat patterns with the longer treatment.
Why It Matters
Understanding dose-response relationships in potential CFS treatments could help optimize therapy protocols and improve outcomes for patients. The integration of both patient-reported scales and objective thermal imaging provides a multimodal assessment approach that may better capture treatment effects in this complex condition.
Observed Findings
- 60-minute moxibustion sessions produced lower fatigue scores than 30-minute sessions (FS-14 physical fatigue: 5.00 vs 6.00, p=0.003; total FS-14: 8.00 vs 9.00, p=0.012).
- Both treatment groups showed increased thermal radiation values; only the 60-minute group showed thermal changes comparable to healthy controls.
- Strong correlations were observed in the 60-minute group between symptom improvement and thermal changes in multiple body regions (upper chest, abdomen, limbs, spine, and renal regions).
- Treatment duration demonstrated a positive dose-effect relationship with clinical response and thermal imaging improvements.
Inferred Conclusions
- Longer duration (60-minute) moxibustion sessions are associated with superior symptom improvement compared to shorter (30-minute) sessions in female CFS patients.
- Thermal imaging changes correlate with symptom improvements and may serve as an objective biomarker for treatment response.
- Optimal clinical response to long-snake-like moxibustion requires 60-minute treatment duration under this protocol.
Remaining Questions
- How do moxibustion outcomes compare to standard medical treatments or placebo controls in CFS?
- Do these findings apply to male CFS patients or to patients with different CFS severity profiles?
What This Study Does Not Prove
This study does not establish that moxibustion is more effective than standard medical treatments or placebo, as there was no placebo control or conventional therapy comparison group. The study was limited to female patients, so findings may not generalize to males. Correlation between thermal changes and symptom improvement does not prove causation, and the mechanism by which moxibustion might benefit CFS remains unclear.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
