Plain English summary of protocol
Background and study aims
Osteoarthritis, a common joint disorder, is the most common form of arthritis in the world. The knee joint is the most common site affected by osteoarthritis in the oriental population. Joint pain caused by knee osteoarthritis can severely impair the patients quality of life. The purpose of this study is to observe whether a Chinese medicinal therapy, infrared laser moxibustion, provides greater relief from pain and joint stiffness and improved function.
Who can participate?
Patients aged 50 years or older, male or female, undergoing knee osteoarthritis treatment can participate in the study.
What does the study involve?
Patients with knee osteoarthritis were randomly divided into real and sham laser moxibustion groups. Patients received 10.6 μm infrared laser moxibustion and sham laser moxibustion treatment. Patients in both groups received 20 minutes of treatment, three times per week for 4 weeks. The effects of treatment were assessed before, mid-term (after 2 weeks), at the end (after 4 weeks) and 4 weeks post-treatment termination. Time taken to walk 50 yards was also calculated.
What are the possible benefits and risks of participating?
Infrared laser moxibustion can reduce pain and improve knee joint stiffness and function in patients with knee osteoarthritis. Some patients have had local skin flushing or blistering (not instantly, but usually one day after treatment) at the site of irradiation. Usually the blister was naturally absorbed within a day or two without obvious scarring of the skin.
Where is the study run from?
Longbai Community Health Service Center in Shanghai Minhang District, China.
When is the study starting and how long is it expected to run for?
The study started in August 2010 and recruitment ended in July 2011.
Who is funding the study?
The study was supported by:
1. National Basic Research Program of China
2. National Natural Science Foundation of China
3. The Key Program of State Administration of Traditional Chinese Medicine of China
4. The Shanghai Municipal Science Foundation

| Scientific title | Effects of CO2 infrared laser moxibustion on patients with knee osteoarthritis: a double-blind, randomized, controlled study |
| Study objectives | The hypothesis is that the CO2 infrared laser moxibustion can reduce pain and improve knee joint stiffness and function in patients with knee osteoarthritis. |
| Ethics approval(s) | Institutional Review Board of Shuguang Hospital Affiliated Shanghai University of Traditional Chinese Medicine. The study was approved on 14 June 2007. |
| Health condition(s) or problem(s) studied | Patients with knee osteoarthritis |
| Intervention | Patients with knee osteoarthritis were randomly divided into real and sham laser moxibustion groups. Patients received 10.6 μm infrared laser moxibustion and sham laser moxibustion treatment on Dubi (ST-35) leg acupoint symmetrically. Patients in both groups received 20 minutes of treatment, three times per week for 4 weeks. |
| Intervention type | Other |
| Primary outcome measure | WOMAC (VAS3.1) Questionnaire was applied to assess the therapeutic effects in terms of joint pain, stiffness, and functional disorder of the participants after 2 weeks and 4 weeks of the treatment initiation, and the long-term effects were also assessed 4 weeks post-treatment. |
| Secondary outcome measures | The 50-yard walking time was assessed and recorded among the participants after 2 weeks and 4 weeks of the treatment as well as 4 weeks post-treatment to observe improvements in walking. In the follow-up, we asked the participants to assess their therapeutic effects and guess their group assignment to assess the masking effectiveness of the trial. Additionally, the participants would also be asked whether they thought the treatment were safe. |
