摘要：According to the traditional Chinese medicine theory, moxa floss is the best material for moxibustion; the effect of moxibustion is closely related to the habitats of moxa floss, among which Qichun County, Hubei Province, China, is considered as the genuine origin. However, this view has not been validated by clinical studies. Moxibustion has been proven effective in alleviating pain and improving physical function and quality of life for patients with knee osteoarthritis (KOA). This trial aims to determine whether the habitat of moxa floss contributes to the effect of moxibustion and to validate the effectiveness of moxibustion for KOA. This is a three-armed, randomized, double-blinded, sham-controlled trial. A total of 350 patients with moderate to severe primary KOA will be randomly allocated to groups A, B, or C with a 2:2:1 ratio. Moxa stick moxibustion using moxa floss from different habitats will be applied in two experimental groups: group A, moxa floss from the habitat of Qichun County, Hubei Province, China; and group B, moxa floss from the habitat of Nanyang County, Henan Province. Group C will use non-moxa floss for sham moxibustion as control. Patients will be treated for 20 min per session, for three sessions per week for 2 weeks, and followed up for 4 weeks. The primary outcome will be the change from baseline in the pain score of the Western Ontario and McMaster Osteoarthritis Index (WOMAC) at week 2. Secondary outcomes will include a change in the WOMAC pain score at week 6; the visual analogue scale for knee pain, the total WOMAC score, the WOMAC stiffness score, the WOMAC function score, the patient global assessment, and the responder criteria at weeks 2 and 6. Adverse events will be assessed throughout the study. This trial will help to identify the effectiveness of moxibustion for KOA and whether the habitat of moxa floss contributes to the effect of moxibustion.
