Study Details

Study Description

Brief Summary

This study aims to assess the feasibility, effectiveness and safety of moxibustion for symptom management and function improvement in patients with knee osteoarthritis, compared to usual care group.

Condition or Disease Intervention/Treatment Phase
  • Other: Moxibustion treatment plus usual care
  • Other: Usual care alone group
Phase 1/Phase 2

Detailed Description

Knee osteoarthritis (OA) is a common joint disease and a leading cause of pain and physical disability in older people. Its symptoms, including pain and physical disability, significantly affect patient's quality of life, and increased depression has been observed in patients with greater pain due to knee OA. Current management options include exercise, weight reduction, Non-steroidal anti-inflammatory drugs (NSAIDs) and other pain medication, intra-articular injections of steroid or hyaluronan, arthroscopic surgery and joint replacement. Except exercise and weight reduction, no known interventions have shown definitive evidence of benefits and safety for knee OA. Thus, it is still worth exploring effective and safe management options for knee OA patients.

Moxibustion is one of traditional Asian medicine using the heat stimulation by burning mugwort (mainly Artemisia vulgaris or Artemisia argyi) on acupuncture points, and regarded as a subtype of acupuncture. Previous literatures reported its use on chronic conditions including gastrointestinal disease, hypertension, musculoskeletal pain, cancer care, gynecological conditions and stroke rehabilitation solely or in combination with routine care or other traditional medicine. However, studies adequately evaluating effects and safety of moxibustion for patients with knee OA are insufficient. Given the gaps between little evidence for effects and safety of moxibustion for knee osteoarthritis and its wide use in clinical practice, the investigators attempted to assess the feasibility, effectiveness and safety of moxibustion for patients with knee osteoarthritis.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Moxibustion treatment plus usual care

Other: Moxibustion treatment plus usual care
Treatment group received moxibustion treatment three times a week for 4 consecutive weeks, totally 12 sessions of treatment in addition to usual care to manage their knee OA. Moxibustion points include six local acupuncture points on affected knee joint. Up to two additional tender points will be allowed, if necessary. If participants feel knee pain on both knee joints, study practitioners will provide treatment on both knee. We will use smokeless indirect moxibustion made of wormwood with a diameter of 1.9 centirmeter and a length of 2.1 centimeter in a cylindrical form for this study (Haitnim Bosung Inc, Korea). Free participant-practitioner interaction will be allowed during the treatment session. Expected total time of each treatment session will be 40 - 60 minutes.
Other Names:
  • Smokeless indirect moxibustion produced by Haitnim Bosung Inc, Korea.
  • No Intervention: usual care alone

    Other: Usual care alone group
    Usual care alone group can receive or use any kind of treatment other than moxibustion treatment provided as study intervention, which includes surgery, conventional medication, physical treatment, acupuncture, herbal medicine, over-the-counter drugs and other active treatment. This also applies to the moxibustion treatment group. Education material of information on knee osteoarthritis and current management option and self-exercise sheet with a yoga-mat to enhance regular exercise will be provided in both groups at baseline.

    Outcome Measures

    Primary Outcome Measures

    1. knee pain measured by Western Ontario MacMaster (WOMAC) pain subscale [4 weeks from baseline]

      The primary outcome is the knee pain measured by WOMAC pain subscale at 4 weeks from baseline.

    Secondary Outcome Measures

    1. The change from baseline to 4, 8 and 12 weeks in the Short Form Health Survey (SF)-36 [at base line, 4 ,8 and 12 weeks later after allocation]

    2. The change from baseline to 4, 8 and 12 weeks in the Beck Depression Inventory(BDI) [at base line, 4 ,8 and 12 weeks later after allocation]

    3. The change from baseline to 4, 8 and 12 weeks in the Patient global assessment [4 ,8 and 12 weeks later after allocation]

      Practitioners and participants will evaluate the improvement of knee joint symptoms after treatment. They can chose one of the following 5 grades: Excellent, Good, Fair, Poor and Aggravation.

    4. The change from baseline to 4, 8 and 12 weeks in the physical performance test [at a baseline, 4 ,8 and 12 weeks later after allocation]

      Timed-stand test/standing balance test/Six minue walk test

    5. The change from baseline to 4, 8 and 12 weeks in the Numeric Rating Scale (NRS) for pain [at a baseline, 4 ,8 and 12 weeks later after allocation]

    6. The change from baseline to 4, 8 and 12 weeks in the Safety measurement [at a baseline, 4 ,8 and 12 weeks later after allocation]

    7. The change from baseline to 4, 8 and 12 weeks in the other WOMAC subscale and global score [at base line, 4 ,8 and 12 weeks later after allocation]
