OBJECTIVETo investigate and research the appraisal scores of the symptoms and physical signs index for the evaluation of the clinical efficacy of acupuncture and manipulative regulation of knee muscle balance for the treatment of knee osteoarthritis, and provide clinical basis for the treatment.

METHODSFrom January 2008 to December 2009, 121 patients with knee osteoarthritis were randomly divided into two groups. In the treatment group there were 63 cases of 83 knees including 16 males and 47 females, with an average age of (59.88 +/- 7.97) years; in the control group there were 58 cases of 73 knees including 13 males and 45 females, with an average age of (57.95 +/- 10.37) years. The patients in the treatment group were treated with acupuncture plus manipulative regulation of knee muscle balance, and the patients in the control group were treated with Diclofenac Sodium Sustained Release Tablets. The appraisal scores of the symptoms and physical signs index, numerical rating scale of pain, joint function, joint swelling were evaluated before and after the treatment, as well as 3 months after the treatment. All data were statistical analyzed by package SPSS 10.0.

RESULTS1) In the treatment group, before and after treatment the appraisal scores of the symptoms and physical signs index were (39.81 +/- 3.92) and (9.69 +/- 8.08); numerical rating scale of pain were (7.61 +/- 0.97) and (2.17 +/- 2.09); joint function were (1.47 +/- 0.50) and (0.61 +/- 0.58); joint swelling were (1.23 +/- 0.79) and (0.42 +/- 0.52). As well in the control group, above data were (39.89 +/- 3.78), (13.62 +/- 7.83), (7.55 +/- 0.71), (3.34 +/- 2.32), (1.33 +/- 0.47), (0.93 +/- 0.67), an (0.97 +/- 0.88), (0.58 +/- 0.52) respectively. Both group had obvious differences in the appraisal scores of the symptoms and physical signs index, numerical rating scale of pain, joint function, joint swelling between after and before treatment. The comparison between the two groups suggested that after the treatments the treatment group had better therapy effect than those of the control group in the appraisal scores of the symptoms and physical signs index, numerical rating scale of pain, joint function, but both group had no differences in the appraisal scores of joint swelling. 2) After the treatment, 12 patients in the treatment group were clinically cured, 48 had remarkable effects,19 good, and 4 ineffective. As well in the control group, above data were 5, 31, 34 and 3 respectively. Three months after the treatment, above data were 8, 42, 27 and 6 respectively in the treatment group. In the control group, above data were 5, 21, 37 and 10 respectively. The treatment group was superior to the control group after the treatments and 3 months after the treatment.

CONCLUSIONAcupuncture plus manipulative regulation of knee muscle balance can effectively improve the clinical symptoms and knee joint's motor function of patients with knee osteoarthritis, and can avoid the further development of disease. It is a proved effective method for knee osteoarthritis.
