JAMA:针刺对膝关节疼痛可能并没有明显疗效

2014-10-02 MedSci译 MedSci原创

针灸对膝关节疼痛的治疗一直存在争议,有人认为是安慰剂效应,有一些研究则认为是有效的。最新一期JAMA在2014年10月1日上发表一项随机对照研究成果显示针灸对膝关节疼痛是有效的。这项研究采用Zelen设计试验(即在患都知情同意前进行随机入组),以保障患都有更好的依从性。共选择282名50岁以上的慢性膝关节疼痛的志愿都加入家庭医生针灸师治疗计划。患都被随机分为4组,包括没有针灸(对照组, n = 7

针灸对膝关节疼痛的治疗一直存在争议,有人认为是安慰剂效应,有一些研究则认为是有效的。最新一期JAMA在2014年10月1日上发表一项随机对照研究成果显示针灸对膝关节疼痛可能并无显著性疗效。

这项研究采用Zelen设计试验(即在患都知情同意前进行随机入组),以保障患都有更好的依从性。共选择282名50岁以上的慢性膝关节疼痛的志愿都加入家庭医生针灸师治疗计划。

患都被随机分为4组,包括没有针灸(对照组, n = 71),针刺组(n=70),激光针组(n=71),假激光针组(n=70)。患者整个疗程为12周。受试者和针灸操作者均处于盲法状态(对于激光组和假激光组)。对照组并不知道参与试验。研究主要终点为平均膝关节疼痛程度(0分为无疼痛,10分为极严重疼痛,最小临床显著差值MCID为1.8分)和生理功能(采用Western Ontario and McMaster Universities Osteoarthritis Index评分,0-68分,最小临床显著差值为6分)。次要终点为其它疼痛和功能评价,生活质量,整体改变,以及一年随访的结果。研究按ITT原则进行分析,缺失值采用多重填补法。

在治疗12周后和随访1年时,分别有26 (9%)和50 (18%)位参与者失访。分析表明,在治疗12周后,与假激光针组相比,针刺治疗还是激光针刺都没有显著改善疼痛(分别平均差值为-0.4分;95% CI, -1.2 to 0.4, 和 -0.1; 95% CI, -0.9 to 0.7),功能改善在两组分别为 (-1.7; 95% CI, -6.1 to 2.6, 和0.5; 95% CI, -3.4 to 4.4)。与空白组相比,针刺和激光针组能显著改善疼痛,分别为 (-1.1; 95% CI, -1.8 to -0.4, 和-0.8; 95% CI, -1.5 to -0.1),但是在1年随访时,没有显著差异。针刺组与对照组的功能改善在12周相比,功能积分改善 (-3.9; 95% CI, -7.7 to -0.2),但与假激光针组无显著性差异(-1.7; 95% CI, -6.1 to 2.6) ,但在1年时没有差异。各组在次要终点以及严重不良事件方面没有显著性差异。

这项研究表明,超过50岁的中重度膝关节疼痛,无论是针刺还是激光针,并不比假激光针更有益。因此,这项结果认为,并不支持对膝关节疼痛患者采用针刺治疗。

不过当期JAMA还发表了署名Wen Wang的文章,有关针灸对穴位的选择问题,如果穴位选择不正确,也很难有疗效。

该文认为针刺应该基于经络学说,成功能的针灸应该包括刺激到正确的穴位(皮肤区域),尤其是穴位对应的经络,因为不同的经络主导的功能有很大的差异。在研究中也应该考虑这些因素。

虽然本文没有直接质疑上文穴位是否正确,但是作为研究报告时应该详细报告取穴位的方法与位置因素,这样研究结果可能才更具有说服力。
