数十年来，已有实验室工作人员暴露于人体工学危险因素的报道。然而，这些暴露并没有根据实验室或工作组织的类型得到很好的描述。本研究按工作、工作和实验室类型比较了综合医院实验室中上肢 (UE) 姿势和手部活动水平 (HAL) 的生物力学暴露。该研究使用了通过修订版的姿势、活动、工具和处理 (PATH) 方法收集的观察数据，生成了分类暴露的频率。两名调查员在 7 个月的时间里对一家医院的 11 个职位（7 个实验室）的 18 名工人进行了观察。构建了一个分类法来对实验室操作的自动化程度进行分类。总体而言，远端 UE 明显面临较高的姿势应变，特别是手腕/前臂偏差（73% 的观察值）、粗握力（71%）和捏握力（49%）。对于 HAL 类别，61% 的观察结果处于中等范围 (3.3–<6.7)。肩膀和肘部倾向于保持在中立姿势范围内。在所研究的工作类别和实验室类型中，姿势频率相似。当手处于紧握状态时，HAL 较高。与半自动或自动化操作相比，手动操作所占的工作时间比例更高。当使用修订后的 PATH 方法以及分类法时，可以更广泛、更多样化地记录生物力学暴露，涉及暴露变量，例如工作类型、工作或行业组织（包括医院实验室）。
Exposure to ergonomic risk factors has been reported for laboratory workers over decades. However, these exposures are not well characterized with respect to the type of laboratory or work organization. This study compared biomechanical exposure to upper extremity (UE) postures and hand activity levels (HALs) in general hospital laboratories by job, work, and laboratory type. The study used observational data gathered using a revised version of the Posture, Activity, Tools, and Handling (PATH) method, generating frequencies of categorized exposures. Eighteen workers were observed in 11 job titles (seven laboratories) in a single hospital by two investigators over a 7 month period. A taxonomy was constructed to categorize the extent to which the laboratory operations were automated. Overall, there were markedly high exposures to postural strain for the distal UE, especially wrist/forearm deviation (73% of observations), gross grasp (71%), and pinch grip (49%). For the HAL categories, 61% of the observations were in the moderate range (3.3–<6.7). Shoulders and elbows tended to remain in the neutral postural range. Posture frequencies were similar among the job categories studied and laboratory types. HAL was higher when the hand was in a pinch grip. Manual operations represented a higher proportion of work time than semi-automated or automated operations. Biomechanical exposure can be documented more extensively and diversely when using the revised PATH approach along with the taxonomy, with respect to exposure variables, such as the type of job, work, or organization in the industry including the hospital laboratories.
