RESUMEN
<p><b>OBJECTIVE</b>To observe the effects among aconite cake-separated moxibustion, moxibustion and acupuncture for knee osteoarthritis (KOA) with kidney-marrow deficiency and to explore the feasibility of cake-separated moxibustion as a home remedy solution.</p><p><b>METHODS</b>Ninety patients were randomized into an aconite cake-separated moxibustion group, a moxibustion group and an acupuncture group, 30 cases in each one. The acupoints in the three groups were Neixiyan (EX-LE 4), Dubi (ST 35) in the affected side, and bilateral Xuehai (SP 10), Liangqiu (ST 34), Heding (EX-LE 2), Shenshu (BL 23) and Zusanli (ST 36). All the treatment was given for 3 sessions, 10 days as a session with 2 to 3 days between 2 sessions, and once a day. The first 2 courses of aconite cake-separated moxibustion was applied in the hospital and the other 1 session was used at home guided by officer physician. Symptoms and physical signs classification score and life quality scores were recorded before and after treatment and 6 months after treatment, including walking pain, knee pain in stoop and squat, knee discomfort in stair activity and daily discomfort. The effects were evaluated.</p><p><b>RESULTS</b>The symptoms and physical signs classification scores in the three groups after treatment and at follow-up were lower than those before treatment (<0.01,<0.05), and the scores in the aconite cake-separated moxibustion group were better than those in the moxibustion group and acupuncture group (all<0.01). The scores of walking pain, knee pain in stoop and squat, knee discomfort in stair activity and daily discomfort were lower in the three groups after treatment and 6 months after treatment (<0.01,<0.05), and the scores of walking pain and daily discomfort in the aconite cake-separated moxibustion group were lower than those in the moxibustion group and acupuncture group (<0.01,<0.05). After treatments, the cured and markedly effective rate in the aconite cake-separated moxibustion group was 63.3% (19/30); that in the moxibustion group was 50.0% (15/30) and one in the acupuncture group was 43.3% (13/30). The cured and markedly effective rate of aconite cake-separated moxibustion group was more promising than those in the other two groups (both<0.05). At follow-up, the cured and markedly effective rate in the aconite cake-separated moxibustion group was 56.7% (17/30), which was better than 36.7% (11/30) in the moxibustion group and 40.0% (12/30) in the acupuncture group (both<0.05).</p><p><b>CONCLUSION</b>Aconite cake-separated moxibustion can be used for KOA patients with kidney-marrow deficiency, which can improve patients' life quality and is better than moxibustion and acupuncture. The method is feasible as a home remedy solution.</p>
