Conclusions
CFS, fatigue
YANG DEFICIENCY, HEAT
This trial evaluated the effect difference of Long-snake-like moxibustion with different dose of 60-m and 30-m duration, measured by subjective traditional scales and objective medical infrared imaging technology. In the same treatment course, 60-min Long-snake-like moxibustion is superior to 30-min Long-snake-like moxibustion in relieving physical fatigue and overall fatigue status, improving Spleen-Kidney Yang Deficiency symptoms, and raising the low heat state to the level of healthy people. This trial provides evidence for selecting the appropriate treatment duration for Long-snake-like moxibustion in treating CFS, and enriches the content of dose–effect research on moxibustion therapy.
