Abstract

Work-related musculoskeletal pain (MSP) risk assessments by trained observers are often used in ergonomic practice; however, the validity may be questionable. We investigated the predictive value of work-site MSP risk estimates in a prospective cohort study of 1745 workers. Trained observers estimated the risk of MSP (neck, shoulder or low-back pain) using a three-point scale (high, moderate and low risk) after observing a video of randomly selected workers representing a task group. Associations of the estimated risk of pain and reported pain during a three-year follow-up were assessed using logistic regression. Estimated risk of neck and shoulder pain did (odds ratio, OR: 1.45 (95% confidence interval, CI: 1.01-2.08); 1.64 (95% CI: 1.05-2.55)), however, estimated risk of low-back pain did not significantly predict pain (OR: 1.27 (95% CI: 0.91-1.79)). The results show that observers were able to estimate the risk of shoulder and neck pain, whereas they found it difficult to estimate the risk of low-back pain. Practitioner Summary: Work-related musculoskeletal pain risk assessments by observers are often used in ergonomic practice. We showed that observers were able to estimate shoulder and neck pain risk, but had difficulties to estimate the risk of low-back pain. Therefore, observers' risk estimates might provide a useful method for musculoskeletal pain risk assessments.

摘要

工作相关肌肉骨骼疼痛 (MSP) 风险评估由经过培训的观察者经常用于人体工程学实践;然而,其有效性可能值得怀疑。我们在一项针对 1745 名工人的前瞻性队列研究中调查了工作场所 MSP 风险估计的预测价值。训练有素的观察者使用三点量表(高、中、低风险)观察随机选择的代表任务组的工人的视频后,对 MSP(颈部、肩部或下背部疼痛)的风险进行了估计。使用逻辑回归评估了在三年随访期间估计的疼痛风险与报告的疼痛之间的关联。颈部和肩部疼痛的估计风险确实(比值比,OR:1.45(95%置信区间,CI:1.01-2.08);1.64(95%CI:1.05-2.55)),然而,下背部疼痛的估计风险没有显著预测疼痛(OR:1.27(95%CI:0.91-1.79))。结果表明,观察者能够估计肩部和颈部疼痛的风险,而他们发现很难估计下背部疼痛的风险。从业者总结:观察者进行的工作相关肌肉骨骼疼痛风险评估经常用于人体工程学实践。我们表明,观察者能够估计肩部和颈部疼痛的风险,但很难估计下背部疼痛的风险。因此,观察者的风险估计可能为肌肉骨骼疼痛风险评估提供一种有用的方法。
