Brief summary
The purpose of this study is verify the efficacy and safety of Cettum (Electric moxibustion) for patients with knee osteoarthritis.
Detailed description
The investigator targets the patients with knee osteoarthritis. After treatment in 3 groups - Cettum treatment, traditional indirect moxibustion treatment, and usual care groups - the investigators will compare the effects of pain relieving and daily performing improvement. So the investigators will confirm the efficacy of Cettum, and further the best treatment method. In addition, the investigators are going to evaluate the safety of abnormal reaction during the treatment.
Interventions
DEVICECettum
The treatment is applied twice a week for 15 minutes for 6 weeks (12 sessions). 6 points (ST36, ST35, EX-LE4, SP9, SP10, ST34) are used for all the patients assigned to this group and investigator can be added up to 2 points depending on the patient condition. Electric moxibustion, Cettum (20X28X18mm) manufactured by K-medical Co.(Korea) is used.
PROCEDURETraditional indirect moxibustion
The treatment is applied twice a week for 6 weeks (12 sessions). 6 points (ST36, ST35, EX-LE4, SP9, SP10, ST34) are used for all the patients assigned to this group and investigator can be added up to 2 points depending on the patient condition. Traditional indirect moxibustion, Taekeukttum manufactured by Haenglim Seowon Medical Co.(China) is used. A total of three moxibustion cones are applied indirectly to each point per treatment session.
OTHERUsual care
The patients in this group maintain the usual treatment and self-care.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain NRS (Numeric Rating Scale) change | 6 weeks | The Numeric Rating Scale is a unidimensional measure of pain intensity. The 11-point numeric scale ranges from '0' representing 'no pain' to '10' representing 'worst pain imaginable'. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| WOMAC (Western Ontario and McMaster Universities) total | 6 weeks | WOMAC scale is widely used to evaluate the condition of patients with osteoarthritis of the knee, including pain, stiffness, and physical functioning of the joints. The WOMAC scale measures 5 items for pain, 2 for stiffness, and 17 for functional limitation. |
| EQ-5D-5L (EuroQol 5-Dimensions 5-Levels) | 6 weeks | The EQ-5D-5L comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. |
| 100mm Pain VAS (Visual Analogue Scale) | 6 weeks | The patient is asked to indicate their perceived pain intensity along a 100mm horizontal line, where '0' represents 'no pain' and '100', 'unbearable pain'. |
| Temperature sense threshold | 6 weeks | Investigator attaches the temperature sensor to the measurement area and increase or decrease the temperature by starting with reference temperature. Warm pain threshold and heat pain threshold are recorded to compare the difference between the value at baseline and the value at the end of the treatment. |
| Adverse Events | 6 weeks | Any unpredicted symptoms are checked at each visit and if any, the symptom, time of occurrence, and length of duration are recorded and reported. |
| PGA (Patient Global Assessment) | 6 weeks | The patient may choose to answer the question of how much better the symptom has improved compared to the previous treatment: Very good, Good, Fair, Poor, Very poor. |
