Perceived discomfort could indicate an early sign of pain, for example, as a result of a biomechanical load on the musculoskeletal system. Assessing discomfort can, therefore, help to identify workers at increased risk of musculoskeletal disorders for targeted intervention development. We aimed: (1) to identify the optimal cut-off value of neck and low back discomfort among office workers and (2) to evaluate its predictive validity with future neck and low back pain, respectively.
At baseline healthy participants (n = 100) completed questionnaires, including the Borg CR-10 discomfort scale (on a 0-10 scale), and were followed for six months, during which musculoskeletal pain was assessed monthly. Logistic regression analyses were performed to assess the associations of baseline discomfort with the onset of future neck or low back pain. Sensitivity, specificity, and the area under the receiver operating characteristics curve were estimated to identify the optimal discomfort cut-off value predicting future pain.
Borg CR-10 scores ≥ 3.5 for perceived neck and low back discomfort had acceptable sensitivity and specificity to predict future neck and low back pain, respectively. Perceived discomfort at baseline as a dichotomous measure (using the ≥ 3.5 cut-off) was a statistically significant predictor of future neck pain (OR = 10.33) and low back pain (OR = 11.81).
We identified the optimal cut-off value of the Borg CR-10 discomfort scale to identify office workers at increased risk of developing neck and low back pain. These findings might benefit ergonomists, primary health care providers, and occupational health researchers in developing targeted interventions.
感知不适可能表明疼痛的早期迹象，例如，由于肌肉骨骼系统的生物力学负荷。因此，评估不适有助于识别肌肉骨骼疾病风险增加的工人，以便进行有针对性的干预措施开发。我们的目的是：（1）确定办公室工作人员颈部和下背部不适的最佳截断值；（2）分别评估其对未来颈部和下背部疼痛的预测有效性。
在基线时，健康参与者（n=100）完成了问卷，包括 Borg CR-10 不适量表（0-10 级），并随访了六个月，在此期间每月评估肌肉骨骼疼痛。进行逻辑回归分析以评估基线不适与未来颈部或下背部疼痛发作之间的关联。估计灵敏度、特异性和受试者工作特征曲线下的面积，以确定预测未来疼痛的最佳不适截断值。
感知颈部和下背部不适的 Borg CR-10 评分≥3.5 具有可接受的灵敏度和特异性，分别预测未来颈部和下背部疼痛。基线时的感知不适作为二分类测量（使用≥3.5 截断值）是未来颈部疼痛（OR=10.33）和下背部疼痛（OR=11.81）的统计学显著预测因素。
我们确定了 Borg CR-10 不适量表的最佳截断值，以识别出有较高风险发生颈部和下背部疼痛的办公室工作人员。这些发现可能有益于人体工程学家、初级保健提供者和职业健康研究人员开发有针对性的干预措施。
