Study Description

Brief Summary

This is a multicentre, randomised, single blinded, parallel-group design clinical trial to assess the effect of moxa smoke in the treatment using moxibustion for Knee Osteoarthritis.

Condition or Disease Intervention/Treatment Phase
  • Other: Moxibustion
  • Other: Moxa smoke purification device
N/A

Detailed Description

Aim: To assess the effect of moxa smoke in the treatment using moxibustion for knee osteoarthritis.

Design: This is a multicentre, randomised, single blinded, parallel-group design clinical trial. 138 eligible participants will be randomly allocated into 2 groups (moxibustion group or smoke-free moxibustion group) with a 1:1 allocation ratio, and receive 12 sessions of moxibustion treatment over a period of 4 weeks, three sessions per week. Each session will last 30 minutes. The whole study period is 13 weeks, with a 1 week run in period, 4 week treatment phase, and 8 week follow-up phase.The participants will receive moxibustion treatment at three acupoints (EX-LE04,ST35,ST36). In moxa-free smoke moxibustion group, investigators place a purification device(Shenzhen Conyson Electronic Technology Co, Ltd,C200 moxa smoke purification device,Shenzhen,China) at the top of the moxibustion to remove the moxa smoke. The primary measurement outcomes are the mean change in the global scale value of the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC) pain and function scores from baseline to 4 weeks. The secondary outcomes are the Visual Analogue Scale (VAS) and the patient global assessment. Investigators will assess participants at the second visit (before starting moxibustion treatment) and at the 2, 4, 8, and 12 week respectively after the baseline.

Outcome Measures

Primary Outcome Measures

  1. Change in the global scale value of the Western Ontario and McMaster Osteoarthritis Index(WOMAC) score [4 weeks from baseline]

Secondary Outcome Measures

  1. Change in the WOMAC subscales (pain, stiffness, and function) [at baseline(0 week), 2 weeks, 4weeks, 8 weeks and 12 weeks later after allocation]

  2. Mean change in Visual Analogue Scale for the pain intensity [Assessing participants at baseline(0 week), 2 weeks, 4weeks, 8 weeks and 12 weeks later after allocation]

  3. Change of Patient global assessment score [at 2 weeks, 4weeks, 8 weeks and 12 weeks later after allocation]
