Regular physical activity participation is known to promote better mobility and coordination. Although previous research has established that lack of physical activity participation may increase the risk of developing low back pain, the role of physical activity as a predictor of recovery among symptomatic individuals remains unclear.
To evaluate whether: (i) the level of physical activity participation before an acute episode of low back pain predicts recovery within 12 months following the acute pain episode (i.e. index episode); and (ii) participants return to their pre-pain level of physical activity participation 12 months from the index episode.
This study used longitudinal data from the TRIGGERS case-crossover study.
This study was conducted through over-the-phone interviews to participants that presented to 300 primary care clinics with a new episode of acute low back pain.
This study included 999 consecutive patients, aged 18 years or older. Follow-up assessment was completed at 12 months following the index episode.
This is a cohort study where consecutive patients, aged 18 years or older, that presented with a new episode of acute low back pain were recruited between October 2011 and November 2012.
Self-reported level of physical activity participation.
A total of 830 participants completed the study. When comparing participants who reported pain at 12 months follow-up with those without pain, all participants reported similar levels of physical activity participation one week before (p = 0.449), one week after (p = 0.812) and 12 months after the index episode (p = 0.233). The level of physical activity participation before the index episode was not a reliable predictor of presence of pain at either 3 or 12 months follow-up (OR 0.99; 95% CI 0.993 to 1.003; p = 0.523 and OR 1; 95% CI 0.992 to 1.008; p = 0.923, respectively).
Physical activity participation did not predict recovery from the pain episode. Also all participants returned to their pre-pain level of physical activity participation after 12 months.
有研究表明，有规律的体育活动参与有助于提高身体的灵活性和协调性。尽管先前的研究已经确定，缺乏体育活动参与可能会增加患下背痛的风险，但体育活动作为预测有症状个体恢复情况的作用仍不清楚。
评估以下两种情况：（i）在急性下背痛发作前的体育活动参与水平是否预测在急性疼痛发作后 12 个月内的恢复情况（即指数发作）；以及（ii）参与者是否在指数发作后 12 个月恢复到他们疼痛前的体育活动参与水平。
本研究使用了 TRIGGERS 病例交叉研究的纵向数据。
本研究通过电话访谈进行，对象是在 300 家初级保健诊所出现新的急性下背痛发作的患者。
本研究纳入了 999 名连续患者，年龄在 18 岁或以上。在指数发作后 12 个月进行了随访评估。
这是一项队列研究，纳入了年龄在 18 岁或以上的连续患者，他们因新出现的急性下背痛发作而就诊。研究招募时间为 2011 年 10 月至 2012 年 11 月。
自我报告的体育活动参与水平。
共有 830 名参与者完成了研究。与在 12 个月随访时报告有疼痛的参与者相比，所有参与者在指数发作前一周（p = 0.449）、后一周（p = 0.812）和 12 个月后（p = 0.233）的体育活动参与水平相似。指数发作前的体育活动参与水平不能可靠预测 3 个月或 12 个月随访时的疼痛存在情况（OR 0.99；95%CI 0.993 至 1.003；p = 0.523 和 OR 1；95%CI 0.992 至 1.008；p = 0.923）。
体育活动参与并不能预测疼痛发作的恢复情况。而且，所有参与者在 12 个月后都恢复到了疼痛前的体育活动参与水平。
