Abstract：
To investigate the effects of electrical dry needling (DN) plus corticosteroid injection (CSI) on pain, physical function, and global change in patients with osteoarthritis of the knee (KOA).
A prospective, single-blinded, randomized controlled trial.
Pain treatment clinic.
Sixty patients with KOA were randomly assigned to the electrical dry needling plus corticosteroid injection (electrical-DN+CSI) group or CSI group.
The CSI group received glucocorticoid injection only once during the trial, and the electrical-DN+CSI group received glucocorticoid injection combined with 4 sessions of electrical-DN.
The primary outcome was the numerical rating scale at 3 months. The secondary outcomes were the Western Ontario and McMaster Universities Osteoarthritis Index, the time to complete the Timed Up and Go test, and the score of the global rating of change scale at 3 months. A generalized linear mixed-effects model was used to analyze the repeated measurement data.
Baseline characteristics and measurements were similar in the 2 groups. The group by time interaction effect was significant for all variables (P<.05). The electrical-DN+CSI group obtained a more significant reduction in pain intensity and more significant improvement in dysfunction than the CSI group at 3 months (P<.05). The median global rating of change score for the CSI group was +3 (somewhat better), and that for the electrical-DN+CSI group was +4 (moderately better).
Electrical-DN therapy at myofascial trigger points combined with CSI is more effective at alleviating pain, improving dysfunction, and creating global change than CSI alone for patients with KOA. Electrical-DN may be an essential part of treatment for KOA rehabilitation.

摘要：
探讨电干针(DN)加皮质类固醇注射液(CSI)对疼痛的影响,物理功能，膝关节骨性关节炎（KOA）患者的整体变化。
有前景的,单盲,随机对照试验。
疼痛治疗诊所。
60例KOA患者随机分为电干针加皮质类固醇注射（electrical-DN+CSI）组或CSI组。
试验期间，CSI组仅接受一次糖皮质激素注射，电DN+CSI组接受糖皮质激素注射联合电DN4次治疗。
主要结果是3个月时的数字评定量表。次要结果是西安大略省和麦克马斯特大学骨关节炎指数，完成定时启动和启动测试的时间，以及3个月时的全球变化量表评分。采用广义线性混合效应模型对重复测量数据进行分析。
两组的基线特征和测量结果相似。各组各变量的交互效应均显著(P<0.05)。在3个月时，与CSI组相比，电DNCSI组的疼痛强度降低更明显，功能障碍改善更明显（P<0.05）。CSI组的全球变化评分中位数为+3（稍好），电DN+CSI组为+4(中度更好)。
肌筋膜触发点的电DN治疗联合CSI更有效地减轻疼痛，改善功能障碍，并为KOA患者创造比单独CSI的全球变化。Electrical-DN可能是KOA康复治疗的重要组成部分。
