本文以某汽车装配厂为研究对象，对偏离解剖中性的躯干弯曲、扭曲等姿势对人体健康的影响进行了研究。背部疾病病例是指在10个月内向医疗部门报告背部疼痛并符合访谈严重程度标准的工人。参照对象是根据医疗部门记录、访谈和检查随机选择的无背痛的工人。对于最后的95个病例和124个参照物中的每一个，由对病例/参照物状态不知情的分析人员使用视频记录和软件分析系统分析该工作的姿势和举起要求。背部疾病与轻度躯干屈曲[比值比（OR） 4.9, 95%可信区间（95% CI） 1.4-17.4]、严重躯干屈曲（OR 5.7, 95% CI 1.6-20.4）和躯干扭曲或侧弯（OR 5.9, 95% CI 1.6-21.4）相关。暴露于多种姿势和暴露时间越长，风险越高。
A case-referent study was conducted in an automobile assembly plant to evaluate the health effect of trunk postures, such as bending and twisting, that deviate from anatomically neutral. Cases of back disorders were all those of workers who reported back pain to the medical department in a ten-month period and met the severity criteria of an interview. The referents were randomly selected workers free of back pain according to medical department records, an interview, and an examination. For each of the final 95 cases and 124 referents, the job was analyzed for postural and lifting requirements with a video recording and software analysis system by analysts blinded to the case/referent status. Back disorders were associated with mild trunk flexion [odds ratio (OR) 4.9, 95 % confidence interval (95 % CI) 1.4-17.4], severe trunk flexion (OR 5.7, 95 % CI 1.6-20.4), and trunk twist or lateral bend (OR 5.9, 95 % CI 1.6-21.4). The risk increased with exposure to multiple postures and increasing duration of exposure.
