Abstract

To observe the differences for knee osteoarthritis (KOA) with yang-deficiency and cold-stagnation syndrome among acupuncture plus ginger moxibustion at Heding (EX-LE 2) on the affected side, simple acupuncture and simple ginger moxibustion at the same acupoint. Ninety patients were randomly assigned into an acupuncture group, a ginger moxibustion group and a combination group, 30 cases in each one. Acupuncture was used in the three groups at bilateral Liangqiu (ST 34), Xuehai (SP 10), and Dubi (ST 35), Neixiyan (EX-LE 4), Yanglingquan (GB 34), Zusanli (ST 36), Yinlingquan (SP 9), Sanyinjiao (SP 6), Xuanzhong (GB 39), Taichong (LR 3) on the affected side. Acupuncture at the affected Heding (EX-LE 2) was applied in the acupuncture group; ginger moxibustion at the affected Heding (EX-LE 2) in the ginger moxibustion group; ginger moxibustion after acupuncture at Heding (EX-LE 2) in the combination group. The treatment was given once a day, and 10 treatments made one session. There were 2 days at the interval between 2 sessions. Before and after (22/30), which was significantly higher than 46.7% (14/30) of the acupuncture group and 20.0% (6/30) of the ginger moxibustion group (both P<0.05), and the rate of the acupuncture group was higher than that of the ginger moxibustion group (P<0.05). Conclusion Based on acupuncture, ginger moxibustion at the affected Heding (EX-LE 2) after acupuncture at the same acupoint are more effective than simple acupuncture at the affected Heding (EX-LE 2) and simple ginger moxibustion at the acupoint for KOA with yang-deficiency and cold-stagnation syndrome. two-session treatment, knee function scores, visual analogue scale (VAS) score, and present pain intensity (PPI) score were compared in the three groups. The clinic effects were evaluated too. After treatment, the knee function scores of the three groups were all higher than those before treatment (all P<0.05), and the VAS score and PPI score were lower (all P<0.05). The differences before and after treatment for knee function, VAS and PPI score of the combination group were higher than those of the other two groups (all P<0.05), and the differences of the acupuncture group were higher than those of the ginger moxibustion group (all P<0.05). The cured and remarkable effective rate of the combination group was 73.3% (22/30), which was significantly higher than 46.7% (14/30) of the acupuncture group and 20.0% (6/30) of the ginger moxibustion group (both P<0.05), and the rate of the acupuncture group was higher than that of the ginger moxibustion group (P<0.05). Based on acupuncture, ginger moxibustion at the affected Heding (EX-LE 2) after acupuncture at the same acupoint are more effective than simple acupuncture at the affected Heding (EX-LE 2) and simple ginger moxibustion at the acupoint for KOA with yang-deficiency and cold-stagnation syndrome.
