目的：这项研究进行评估的物理/人体工程学的暴露，可能会导致肌肉骨骼损伤的桩Drivers.Participants：桩Drivers在大波士顿area.Methods：打桩工作的层次分类开发的任务和活动内定义的7个主要打桩操作。采用PATH（作业、活动、工具和搬运）方法表征打桩作业的暴露。结果：共对29名打桩工进行了8，301次观察，共观察了6个作业点。滞后操作具有最高的观察百分比与非中性躯干（46.8%），腿（41.0%）的姿势，以及最低的百分比之一，在稳定的地面上工作（9.0%），在滞后操作期间观察到。支撑作业在稳定地面上作业的比例最低（0.3%）。泥浆护壁施工在稳定地面上的工作百分比也较低（6.0%）。与笨拙的躯干和腿部姿势相比，手臂姿势不太频繁地观察到尴尬或非nutral.Conclusion：结果表明，显着的暴露，可能会导致肌肉骨骼损伤的背部和腿部的打桩机。不稳定的地面条件似乎是这项工作的主要问题之一。
Objective: The study was conducted to assess the physical/ergonomic exposures that may lead to musculoskeletal injuries of Pile Drivers.Participants: Pile Drivers in the Greater Boston area.Methods: A hierarchical taxonomy for pile driving work was developed with tasks and activities defined within each of seven main pile driving operations. Exposures were characterized for the pile driving work with the PATH (Posture, Activity, Tools, and Handling) method. Data on working posture were collected for three main body parts: legs, arm and trunk.Results: A total of 8,301 observations were made on 29 Pile Drivers, on a total of 6 work sites. The lagging operation had the highest percentage of observations with non-neutral trunk (46.8%), and leg (41.0%) postures, as well as one of the lowest percentages for working on stable ground (9.0%) as observed during the lagging operation. The bracing operation had the lowest percentage for working on stable ground (0.3%). The slurry wall operation also had a low percentage of work on stable ground (6.0%). Compared to the awkward trunk and leg postures, the arm postures were less frequently observed as being awkward or non-neutral.Conclusion: The results indicate of significant exposures that could lead to musculoskeletal injuries of the back and legs for the Pile Drivers. The unstable ground conditions seemed to be one of the main concerns for this job.
