Detailed Description
Objective: This pilot randomized controlled trial (RCT) will preliminary examine the effects of an electromoxibustion device and knee health education on reliving knee osteoarthritis (OA) pain.
Method Design: This pilot RCT will embed a two-arm randomized control trial. The project will recruit 48 participants with knee OA. Eligible participants will be randomized into 2 groups - (1) Electromoxibustion, or (2) knee health education at 1:1 ratio.
Interventions: Participants in the electromoxibustion group will receive electromoxibustion using a knee-brace-like device which produces thermal stimulation with a moxa pad inside (Fort Mayer, Guangzhou, China); participants in the Knee health education group will attend 2 sessions (120 minutes each, 1-week apart) of health education related to knee OA symptom management.
Outcome measures: (1) Pain severity numerical rating scale (NRS) (Primary outcome); (2) Western Ontario and McMaster University Osteoarthritis Index (WOMAC) for pain, physical function, and stiffness related to knee osteoarthritis; (3) Short Form-6 Dimensions for quality of life; (4) Timed Up & Go Test (TUG); (5) Fast Gait Speed (FGS) for knee functioning.
Statistical Analysis of quantitative data: Descriptive statistics will be used to describe the socio-demographic characteristics of the participants. A mixed-effects model with consideration of repeated measures and dropout by including all available data points (intention-to-treat analysis) to compare the electromoxibustion with the knee health education control group. SPSS version 23.0 will be used in this study.

- willing to provide informed consent.
Exclusion Criteria:
- medical diagnoses or conditions that preclude individuals from active participation (e.g. dementia, post-stroke syndrome, alcohol or drug abuse);
- knee pain related to other conditions (cancer, fracture, rheumatoid arthritis, rheumatism) as screened according to the red flags for further investigation or referral in the National Clinical Guideline Centre 2014 Guidelines for Osteoarthritis of the knee (National Clinical Guideline Centre, 2014);
- presence of skin lesions or infections at the treatment sites;
- ever had knee replacement surgery or knee joint implant; and
- ever received moxibustion, electromoxibustion or steroid injection for knee pain over the past 6 months; Further investigation or referral, either at the screening or during the study, will be made when necessary.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Electromoxibustion
Participants in this group will receive electromoxibustion using a knee-brace-like device which produces thermal stimulation with a moxa pad inside (Fort Mayer, Guangzhou, China).
|
Electromoxibustion is a electric device that mimic the burning or moxa.
Subjects in this group will receive electromoxibustion using a knee-brace-like device which produces thermal stimulation with a moxa pad inside.
The treatment will be delivered 3 times per week for 4 weeks.
|
Active Comparator: Knee health education
Participants in this group will attend 2 sessions (120 minutes each, 1-week apart) of health education related to knee OA symptom management.
|
Subjects in this group will attend 2 lessons (120 minutes each) of health education related to knee OA symptom management in a small group of 5-7 subject.
The course content is developed from the course materials from the websites of Elderly Health Service, Department of Health, Hong Kong SAR.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain severity numerical rating scale, NRS
Time Frame: Week 4
|
The Numerical Pain Rating Scale (NPRS) is a subjective measure in which individuals rate their pain on an eleven-point numerical scale.
The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain).
It has been shown that a composite scoring system including best, worse, and current level of pain over the last 24 hours was sufficient to pick up changes in pain intensity with maximal reliability.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Western Ontario and McMaster University Osteoarthritis Index (WOMAC)
Time Frame: Week 4
|
The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis.
It is a self-administered questionnaire consisting of 24 items divided into 3 subscales.The
WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68).
|
Week 4
|
Short Form-6D
Time Frame: Week 4
|
The SF-6D, which is derived from the 36-item Short Form Health Survey (SF-36), is one of the most widely used generic measures of HRQoL in clinical trials.
The score ranges from 0 to 1.
|
Week 4
|
Timed Up & Go Test (TUG)
Time Frame: Week 4
|
The Timed Up and Go test (TUG) is a simple test used to assess a person's mobility and requires both static and dynamic balance.
|
Week 4
|
Fast Gait Speed (FGS)
Time Frame: Week 4
|
Subjects will be asked to walk 4 metres at their normal pace.
Their gait speed in metres per second will be calculated.
