The aim of this pilot study was to analyze postures during the work of neurologists with respect to their occupational activities.
A total data material of 64.8 h (3885.74 min) of nine (three m/six f) neurologists (assistant physicians) was collected. Kinematic data were collected using the CUELA system (electro-goniometry). In addition, the occupational tasks performed on-site were subject to a detailed objective activity analysis. All activities were assigned to the categories "Office activities" (I), "Measures on patients" (II) and "Other activities" (III). The angle values of each body region (evaluation parameters) were evaluated according to ergonomic ISO standards.
Only 3.4% of the working hours were spent with (II), while 50.8% of time was spent with (I) and 45.8% with (III). All tasks of category (II) revealed an increased ergonomic risk to the head, neck, trunk and back areas. During category (I) especially neck and back movements in the sagittal plane showed higher ergonomic risk levels.
Despite frequently performed awkward body positions in (II), the ergonomic risk is considered as rather low, since the percentage time share totaled only 3.4%. As a result, "Office activities" have been detected as high predictor to cause stress load on the musculoskeletal system in the daily work of neurologists.
本初步研究的目的是分析神经科医生工作时的姿势与其职业活动的关系。
收集了9名（3名男性/6名女性）神经科医生（助理医师）总计64.8小时（3885.74分钟）的数据资料。使用CUELA系统（电子测角法）收集运动学数据。此外，对现场执行的职业任务进行了详细的客观活动分析。所有活动被归类为“办公室活动”（I）、“对患者的检查”（II）和“其他活动”（III）。根据人体工程学ISO标准评估每个身体部位的角度值（评估参数）。
只有3.4%的工作时间用于（II），而50.8%的时间用于（I），45.8%的时间用于（III）。（II）类的所有任务显示头部、颈部、躯干和背部区域的人体工程学风险增加。在（I）类中，尤其是矢状面的颈部和背部运动显示出较高的人体工程学风险水平。
尽管（II）类中经常出现身体姿势 awkward，但人体工程学风险被认为相当低，因为其时间占比总计仅为3.4%。因此，“办公室活动”被发现是神经科医生日常工作中导致肌肉骨骼系统压力负荷的高预测因素。 （注：原文中“awkward”未准确翻译，可根据实际语境调整更合适的表述，比如“别扭的”等 ）
