An observational work-sampling technique--Posture, Activity, Tools, and Handling (PATH)--was used to describe the prevalence of awkward postures and other physical risk factors for shoulder symptoms among a purposive sample of 11 small-scale commercial crab pot fishing crews. Fishing activities with awkward shoulder postures included hooking the buoy, feeding the rope into the hydraulic puller, and handling the crab pots. Increasing the size of the crew decreased the frequency of awkward shoulder postures for the captain but not for the mate. Awkward shoulder postures varied by technique, task distribution, equipment, and boat characteristics and setup, indicating these factors may be important determinants of exposure. Care should be taken in assuming personal techniques drives ergonomic exposure variability among these small-scale commercial fishermen.
采用观察性工作抽样技术——姿势、活动、工具和处理（PATH）——来描述在 11 个小规模商业螃蟹捕捞队的有目的样本中，不良姿势和其他肩部症状的物理风险因素的流行率。具有不良肩部姿势的捕捞活动包括钩住浮标、将绳索喂入液压拉拔器以及处理螃蟹笼。增加船员的规模会降低船长的不良肩部姿势的频率，但对大副没有影响。不良肩部姿势因技术、任务分配、设备以及船只的特点和设置而有所不同，这表明这些因素可能是暴露的重要决定因素。在假设个人技术是这些小规模商业渔民的人体工程学暴露变异性的驱动因素时，应谨慎行事。
