To verify the clinical efficacy of heat-sensitive moxibustion in treatment of knee osteoarthritis (KOA).
Sixty cases of KOA were randomly divided into a heat-sensitive moxibustion group and a conventional moxibustion group, 30 cases in each one. Dubi (ST 35), Yanglingquan (GB 34), Zusanli (ST 36) and Heding (EX-LE 2) on the affected side were selected in two groups. In heat-sensitive moxibustion group, the techniques of circling moxibustion, sparrow-pecking moxibustion, moving moxibustion and mild moxibustion were applied. In conventional moxibustion group, the mild moxibustion was used, 2 to 3 cm far from the skin of the acupoints selected. Lysholm scale for the assessment of knee joint function was adopted to evaluate the efficacy. The scores of joint pain, morning stiffness, joint swelling and walking ability were compared before and after treatment in two groups.
The scores of joint pain, morning stiffness, joint swelling and walking ability after treatment were all apparently improved as compared with those before treatment in either group (all P < 0.05). The improvement in the above-mentioned indices in heat-sensitive moxibustion group was much more apparent as compared with that in conventional moxibustion group (all P < 0.01). The effective rate was 90.0% (27/30) in heat-sensitive moxibustion group and was 73.3% (22/30) in conventional moxibustion group. The effective rate in heat-sensitive moxibustion group was obviously superior to that in conventional moxibustion group (P < 0.01).
The efficacy of heat-sensitive moxibustion is superior to that of conventional moxibustion in the treatment of KOA. This therapy can more significantly improve the symptoms and physical signs of the patients with KOA.
