Abstract：
OBJECTIVE: To investigate the effects of adding pain science or ergonomics messages to guideline advice on feelings of reassurance and management intentions among people with acute low back pain (LBP). DESIGN: Three-arm parallel-group randomized experiment. METHODS: We recruited people with acute LBP (pain for ≤6 weeks) to participate in an online experiment. Participants were randomized at a 1:1:1 ratio to one of three groups: guideline advice alone or guideline advice with the addition of brief pain science or ergonomics messages. The intervention was delivered via prerecorded videos in all 3 groups. Coprimary outcomes were reassurance that (1) no serious condition is causing LBP and (2) continuing with daily activities is safe. Secondary outcomes were perceived risk of developing chronic pain, management intentions (bed rest, see a health professional, see a specialist, and imaging), credibility, and relevance of the advice in addressing the participant\'s concerns. RESULTS: Two thousand two hundred ninety-seven responses (99.3% of 2,313 randomized) were analyzed. Adding brief pain science or ergonomics messages to guideline advice did not change reassurance that LBP was not caused by serious disease. The addition of ergonomics advice provided worse reassurance that it is safe to continue with daily activities compared to guideline advice (mean difference [MD], -0.33; 95% CI: 0.13, 0.53). There was no difference between groups on management intentions. CONCLUSION: Adding pain science or ergonomics messages to guideline advice did not increase reassurance or change management intentions in people with acute LBP. Ergonomics messages may lead to reduced feelings of reassurance. J Orthop Sports Phys Ther 2023;53(12)1-11. Epub 26 September 2023. doi:10.2519/jospt.2023.12090.
摘要：
目的：研究将疼痛科学或人体工程学信息添加到指南建议中对急性下腰痛（LBP）患者的安心感和管理意图的影响。设计:随机三臂平行组.方法：我们招募急性LBP患者（疼痛≤6周）参与一项在线实验。参与者以1：1：1的比例随机分为三组：单独的指南建议或添加简短的疼痛科学或人体工程学信息的指南建议。在所有3组中通过预先录制的视频进行干预。共同的结果是保证（1）没有严重的疾病引起LBP，（2）继续进行日常活动是安全的。次要结果是发展为慢性疼痛的感知风险，管理意图(卧床休息，去看健康专家，去看专家,和成像），信誉,以及解决参与者担忧的建议的相关性。结果：分析了两千二百九十七个反应（2,313个随机数据中的99.3％）。在指南建议中添加简短的疼痛科学或人体工程学信息并没有改变LBP不是由严重疾病引起的保证。与指南建议相比，人体工程学建议的添加提供了更糟糕的保证，即继续进行日常活动是安全的（平均差异[MD]，-0.33；95%CI：0.13，0.53）。两组在管理意图上没有差异。结论：将疼痛科学或人体工程学信息添加到指南建议中并没有增加急性LBP患者的安慰或改变管理意图。人体工程学信息可能会降低人们的安全感。J正交运动物理学，2023年；53（12）1-11。Epub2023年9月26日。doi：10.2519/jospt.2023.12090。
