To explore the actions of electroacupuncture (EA) and the warming needle moxibustion on knee osteoarthritis (KOA) of kidney deficiency and marrow insufficiency pattern/syndrome and compare the clinical effects between these two therapies.
Seventy-four cases of KOA were randomly divided into an electroacupuncture (EA) group and a warming needle moxibustion (WNM) group, 37 cases in each one. The acupoints were Dubi (ST 35), Neixiyan (EX-LE 4), Xuehai (SP 10), Zusanli (ST 36), Yanglingquan (GB 34), etc. In EA group, electric stimulation was given, 5 Hz, continuous wave. In the WNM group, warm needling technique was applied, 2 moxa cones on each acupoint in each time, three treatments a week. Totally, 4 weeks of treatment were required. The indicaices such as WOMAC score, illness severity index and systematic efficacy were adopted to evaluate the efficacy before treatment, 1 session and 2 sessions after treatment separately.
The treatment in either group achieved the effectiveness. The cured and markedly effective rate was 64.7% (22/34) in EA group and was 40.0% (14/35) in WNM group, presenting statistically significant difference in comparison (P < 0.05). But the total effective rate did not indicate significance (P > 0.05). In EA group, the releasing effect of joint pain was obvious (P < 0.01). In the WNM group, the treatment was more advantageous at relieving joint stiffness (P < 0.01). There was no difference in the mean curative time between two groups (P > 0.05).
Electroacupuncture and the warming needle moxibustion have their own advantages in the treatment of KOA of kidney deficiency and marrow insufficiency pattern/syndrome. Electroacupuncture is advantageous at analgesia and the warming needle moxibustion is at relieving joint stiffness. The total efficacy of electroacupuncture is superior to that of the warming needle moxibustion.
