Clinical Study on Electroacupuncture for Knee Osteoarthritis / 上海针灸杂志

ABSTRACT

Objective To observe the clinical efficacy of electroacupuncture (EA) in treating knee osteoarthritis (KOA).Method Sixty KOA patients were randomized into a treatment group and a control group by using random number table, 30 cases each. The control group was intervened by oral administration of Celecoxib capsules, while the treatment group was given EA, 14 d as a treatment course. The changes of relevant cytokines [apelin, tumor necrosis factor (TNF)-α, TNF soluble receptor (TNFsR)-Ⅰ, TNFsR-Ⅱ, interleukin (IL)-1β, and IL-6] in serum of the two groups were observed.Result The intra-group comparisons of the total score, and the scores of pain, stiffness and dysfunction of the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index showed significant differences in both groups (P<0.05); there were significant between-group differences in comparing the total score, and the scores of pain, stiffness and dysfunction of the WOMAC index after the treatment (P<0.05). The Visual Analogue Scale (VAS) scores were changed significantly after the intervention in both groups (P<0.05); there was nosignificant difference in comparing the VAS score between the two groups after the treatment (P>0.05). The levels of IL-6, TNF-α and TNFsR-Ⅰ were significantly changed after the treatment in both groups (P<0.05); the level of IL-1β was markedly changed after the intervention in the control group (P<0.05); there was a significant change in the level of apelin after the intervention in the treatment group (P<0.05), and there was a significant difference in comparing the level of apelin between the two groups after the treatment (P<0.05).Conclusion EA can produce a satisfactory efficacy in treating KOA; it can significantly improve the symptoms and signs, and mitigate pain and symptoms through regulating the expressions of cytokines.
