Placebo used in a new study to treat moderate-to-severe lower back pain had no effect on pain or physical function over a three-month period, according to new research published in JAMA Network Open.

根据JAMA Network Open发表的新研究，在一项新研究中使用的安慰剂用于治疗中背部疼痛，对三个月内的疼痛或身体功能没有影响。

The study, which included 120 adults with lower back pain, also found that the use of the placebo did not influence participants' beliefs about the treatment or satisfaction with care.

这项研究包括120名下背部疼痛的成年人，还发现安慰剂的使用不会影响参与者对治疗或对护理满意的信念。

The researchers, from the University of Washington in Seattle, said their findings are important because they add to a growing body of evidence that placebos alone may not provide lasting benefit for chronic pain.

来自西雅图华盛顿大学的研究人员说，他们的发现很重要，因为他们增加了越来越多的证据表明，仅安慰剂可能不会为慢性疼痛带来持久的好处。

"Our findings suggest that, at least in the short term, the use of a placebo in the setting of routine care for back pain does not appear to exert an effect on pain, physical function, or patient-reported outcomes," they wrote.

他们写道：“我们的发现表明，至少在短期内，在常规护理背痛的情况下使用安慰剂似乎不会对疼痛，身体功能或患者报告的结果产生影响。”

The researchers said they were surprised by their findings, given that previous studies have shown that placebos can have a significant impact on pain perception in the lab setting.

研究人员说，鉴于先前的研究表明，安慰剂对实验室环境中的疼痛感可能产生重大影响，因此他们对他们的发现感到惊讶。

However, they said the new study was conducted in a real-world setting, which may explain why the effects of the placebo were smaller and did not last as long.

但是，他们说，这项新研究是在现实世界中进行的，这可以解释为什么安慰剂的影响较小，并且持续不长。

The researchers also noted that the study was relatively small and more research is needed to fully understand the role of placebos in pain management.

研究人员还指出，这项研究相对较小，需要更多的研究来充分了解安慰剂在疼痛管理中的作用。

"These findings may not be generalizable to other patient populations, such as those with cancer pain or headache, or to other chronic pain conditions," they said.

他们说：“这些发现可能无法推广到其他患者人群，例如患有癌症疼痛或头痛的患者或其他慢性疼痛状况。”

"The short-term nature of this study also limits the detection of potential long-term effects of placebo on pain and function."

“这项研究的短期性质还限制了安慰剂对疼痛和功能的潜在长期影响的检测。”

Despite the null findings, the researchers said their study highlights the importance of considering the psychological and social factors that may influence pain perception and response to treatment.

尽管发现无效，但研究人员说，他们的研究强调了考虑可能影响疼痛感知和对治疗反应的心理和社会因素的重要性。

They said it is possible that the placebo group in their study experienced less improvement in pain and function because they had higher expectations for the treatment or were less satisfied with the care they received.

他们说，他们的研究中的安慰剂组可能在疼痛和功能方面的改善较小，因为他们对治疗的期望更高，或者对接受的护理不太满意。

"It is also possible that the members of the placebo group had a less positive anticipation of the treatment effect or were less engaged in the treatment process," they said.

他们说：“安慰剂组的成员对治疗效果的预期较少，或者参与治疗过程的积极期望较低。”

The researchers said they plan to conduct further studies to examine the role of these factors in determining the effects of placebos for chronic pain.

研究人员说，他们计划进行进一步的研究，以研究这些因素在确定安慰剂对慢性疼痛影响的作用中的作用。

The new study is the latest to examine the role of placebos in treating chronic pain. A 2019 study published in the journal Science found that placebos could reduce pain in patients with osteoarthritis of the knee.

这项新研究是检查安慰剂在治疗慢性疼痛中的作用的最新研究。 2019年发表在《科学》杂志上的一项研究发现，安慰剂可以减轻膝盖骨关节炎患者的疼痛。

However, another study published in 2020 in the journal Annals of Internal Medicine found no evidence that placebos were effective for treating chronic low back pain.

但是，另一项在2020年发表在《内科杂志》杂志上的研究没有证据表明安慰剂可有效治疗慢性腰痛。

The researchers said their findings have implications for the way chronic pain is treated.

研究人员说，他们的发现对慢性疼痛的治疗方式具有影响。

"Despite the widespread interest in exploring the role of placebo effects in pain modulation, there is limited evidence to support the use of placebos in the setting of routine care for chronic pain," they said.

他们说：“尽管对探索安慰剂作用在疼痛调节中的作用的兴趣普遍存在，但仍有有限的证据支持安慰剂在常规护理慢性疼痛的情况下使用。”

"Our findings add to a growing body of literature suggesting that, at least in the short term, placebos alone may not provide benefit for patients with chronic pain."

“我们的发现增加了越来越多的文献，这表明至少在短期内，仅安慰剂可能不会为患有慢性疼痛的患者带来好处。”
