To observe the therapeutic effect of different schemes of mild moxibustion for treatment of (yang-deficiency induced cold-accumulation type)knee osteoarthritis (KOA).
Fifty-nine KOA patients were chosen and randomly divided into control group (n =30) and test group (n =29). Patients of the control group were treated by mild moxi- bustion of Neixiyan (EX-HE4) and Waixiyan (ST 35) for 30 min, once daily for 14 days (two courses), and those of the test group were treated by mild moxibustion of EX-HE 4 and ST 35 for 30 mini once daily for 7 days (the same to control group), followed by moxibustion of Yaoyangguan (GV 3) and Mingmen (GV 4) once daily for next 7 days more. In addition, patients of the two groups were also treated by routine acupuncture stimulation of EX-HE 4, ST 35, Yanglingquan (GB 34), Kunlun (BL 60), etc. The interval between two therapeutic courses was one day. The Lysholm Knee Score Scale (LKSS) was used to evaluate the therapeutic effect. Visual analogue scale (VAS) was employed to assess the patient's knee-joint pain severity (arthralgia), and scores of morning stiffness, arthrocele, and walking restraint degree of the knee-joint were also evaluated before and after the treatment.
After the treatment, the scores of VAS, morning stiffness, arthrocele and walking restraint degree of the knee-joint of both groups were significantly decreased (P<0. 05), and the scores of the test group were obviously lower than those of the con- trol group (P<0. 05). The effective rate of the test group was 89.66% (26/29)which was obviously higher than that (70.00%, 21/30) of the control group (P<0. 05).
Mild moxibustion of Neixiyan (EX-HE 4) and Waixiyan (ST 35, local acu- points), and Yaoyangguan (GV 3) and Mingmen (GV 4) has a better therapeutic effect for KOA patients than moxibustion of local acupoints only.
