CO2 Laser Moxibustion for Knee Osteoarthritis: Study Protocol for A Multicenter, Double-blind, Randomized Controlled Trial

Background Knee osteoarthritis (OA) is a major cause of disability among the older adults. Few treatments are safe and effective. Moxibustion is commonly used in treating knee OA in Chinese medicine (CM). CO 2 Laser moxibustion device is a substitute for traditional moxibustion, which mimics the eff...

Zusammenfassung:Background Knee osteoarthritis (OA) is a major cause of disability among the older adults. Few treatments are safe and effective. Moxibustion is commonly used in treating knee OA in Chinese medicine (CM). CO 2 Laser moxibustion device is a substitute for traditional moxibustion, which mimics the effects of traditional moxibustion. More data are needed to support its application in knee OA. Objective ObjectiveThe trial aims to assess the effect and safety of CO 2 laser moxibustion in patients with knee osteoarthritis compared with a sham control. Methods This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial. A total of 392 participants were recruited and assigned to the CO 2 laser moxibustion group and sham laser moxibustion group with a 1:1 ratio at 6 outpatient clinics in Shanghai, China. Participants in both groups received treatment at the affected knee(s) at the acupuncture point Dubi (ST 35) and an Ashi point. There were 3 sessions per week for 4 weeks, and an additional 20-week follow-up. Primary outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores at week 4. Secondary outcomes were WOMAC function score, stiffness score and overall score, VAS pain, Short-Form heath survey (SF-36), and patients' global assessment. The serum levels of cytokines involved in progress of knee OA were explored. Safety was assessed during the whole trial. Masking effectiveness was assessed by both participants and treatment providers.This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial.
