Brief summary
Knee osteoarthritis (KOA) a chronic disease with symptoms of persistent pain or rest pain , joint stiffness, numbness, limitation of activity and even disability, with significant associated costs and effects on individuals' life quality. Acupuncture as an approach for the management of chronic pain, is receiving increasing recognition from both the public and professionals. The aim of this study is to indicate the effects of three commonly used acupuncture treatments for KOA.
Detailed description
360 subjects with KOA recruited from six centers will be randomized to six groups ,and receive four-week acupuncture, Electro-acupuncture, Moxibustion ,Warm-needling ,sham-needle, celebrex treatment. The primary outcomes are Visual Analogue Scale (VAS) and WOMAC function score.The Secondary outcomes are WOMAC pain score, WOMAC stiffness score,the Physical Activity Scale of the Elderly (PASE),knee joint swelling measurement and WHO-BREF life quality scale.The follow-up period is six months. This study will be a rigorous,randomized, sham and drug controlled trial focusing on using different kinds of acupuncture treatment for treating KOA.
Interventions
OTHERtreatment1
1. Acupoints：Liangqiu（ST34）,Xuehai（SP10）,Neixiyan（EX-LE4）,Dubi(ST35),Yanglingquan (GB34)and Yinlingquan (SP9) 2. operation: the needles will be manipulated using techniques including lifting, thrusting, twisting, and rotating, until De Qi is achieved for 30 minutes.
OTHERtreatment2
1. Acupoints：Needling points are the same to the above group 2. operation: The electrode will be connected Neixiyan (EX-LE4) and Dubi (ST35) and electrode wire will be connected to the electro-acupuncture apparatus using dilatational wave with a frequency of 2/100 Hz, the current intensity is within participants'tolerance, for 30 minutes.
OTHERtreatment3
1. Acupoints：treating points are the same to the above group 2. Operation: During treatment, participants will choose to sit with knee buckling natural 90 degrees ,with the affected knee(s) exposed. Mild moxibustion are applied at the distance of 2-3 cm away from the skin of both the Neixiyan (EX-LE4) and Dubi (ST35) for 30 minutes.
OTHERtreatment4
1. Acupoints：Needling points are the same to the above group 2. Operation: Warm-needling acupuncture are applied at both Neixiyan (EX-LE4) and Dubi (ST35). That is to insert one zhuang(about 2cm)of Huai Qing Ai on the top of the needle, and burn the moxa at the lower end ,each acupoint applied 2 Zhuang for 30 minutes.
OTHERtreatment5
1. points：Sham Liangqiu（ST34）,Sham Xuehai(SP10), Sham Neixiyan(EX-LE4), Sham Yanglingquan(GB34),Sham Yinlingquan (SP9) 2. Operation: Sham acupuncture with non-meridian and non-acupoint needling method, respectively acupuncture 1cm away lateral to the above sham acupoints with a 0.18 \* 25mm single-use needle with the depth of 1-2mm.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Score change | baseline,2 weeks, 4 weeks ,3 months,6months | Intensity of pain range (lately 3 days' average): 0 =no pain to 10 =worst possible pain. Higher score indicating severe pain. |
| WOMAC function change | baseline,2 weeks,4 weeks ,3 months,6months | The WOMAC function subscale referred to the participant's ability to move around and perform usual activities of daily living. The WOMAC function subscale was comprised of 17 questions regarding the degree of difficulty experienced due to OA in the study knee. The WOMAC function subscale score for each question ranged from 0 (minimum) to 4 (maximum), higher scores signified worse physical function. An overall score range of 0 (minimum) to 68 (maximum), with higher scores indicating worse physical function. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| WOMAC stiffness change | baseline,2 weeks,4 weeks ,3 months,6months | The WOMAC stiffness subscale was comprised of 2 questions regarding the degree of stiffness experienced in the study knee. The WOMAC stiffness subscale score for each question ranged from 0 (minimum) to 4 (maximum), higher scores signified worse stiffness. An overall score range of 0 (minimum) to 8 (maximum), with higher scores indicating more stiffness. |
| PASE change | baseline,2 weeks,4 weeks ,3 months,6months | Physical Activity Scale for the Elderly was comprised of 36 questions regarding physical activity of elderly's house hold,leisure,work performance with different score weight.The higher scores indicating better physical activity. |
| Expectancy questionnaires | baseline | Expectancy questionnaires were comprised of two brief items assessing the expectancy of the patients about acupuncture(or/and)moxibustion. |

| WOMAC pain change | baseline,2 weeks,4weeks ,3 months,6months | The WOMAC pain subscale referred to the patient's pain. It was comprised of 5 items, with each item scored from 0 (minimum) to 4 (maximum), where 4 indicated worst pain condition. An overall score range of 0 (minimum) to 20 (maximum), with higher scores indicating worse physical function. |
