Back pain is common among people working in the sitting position. Quality of the sitting position depends among others on the standard of work station. Dental units are built on the basis of contemporary ergonomic workplace concepts, while medical assistant workstations are typically computer office workstations. The purpose of the study was pain estimation in association with the identification of the spine arrangements during sitting work with better and worse ergonomic adjustment.
The study involved 80 women working in the sitting position suffering from pain - 40 dentists working on dental units with a higher ergonomic potential and 40 medical assistants working on stations with lower ergonomic potential. The study included interviews, pain assessment and working spine arrangements analysis using the ultrasonographic measurement system.
There were exceeds of work parameters in particular segments of the spine observed in all examined persons. The relationship between pain intensity and work parameters as frontal bending amplitude of lumbar spine segment, transversal amplitude of cervical spine segment and transversal amplitude of lumbar spine segment were observed in the group of dentists. There was observed the relationship between pain severity and the values of sagittal bending amplitude of cervical spine segment and thoracic spine segment in the group of medical assistants. Other determinants of pain also have been identified.
Exceeded values of work parameters were observed amongst subjects working both at the higher and the lower ergonomic potential work stations. The working postures of people working in the sitting position are similar only to their external characteristics. Pain depends on working position. The pain intensity is determined by other factors: length of professional experience, duration of the pain, the number of working hours per week, body mass index (BMI). Med Pr 2018;69(5):509-522.
背痛在从事坐姿工作的人群中很常见。坐姿质量尤其取决于工作站的标准。牙科设备是基于当代人体工程学工作场所概念构建的，而医疗助理工作站通常是计算机办公工作站。本研究的目的是在坐立工作期间，结合识别具有较好和较差人体工程学调整的脊柱排列情况来评估疼痛。
该研究纳入了80名患有疼痛的从事坐姿工作的女性——40名在具有较高人体工程学潜力的牙科设备上工作的牙医，以及40名在人体工程学潜力较低的工作站工作的医疗助理。该研究包括访谈、疼痛评估以及使用超声测量系统分析工作时的脊柱排列情况。
在所有被检查者中，均观察到脊柱特定节段的工作参数超标。在牙医组中，观察到疼痛强度与腰椎节段前屈幅度、颈椎节段横向幅度和腰椎节段横向幅度等工作参数之间存在关联。在医疗助理组中，观察到疼痛严重程度与颈椎节段和胸椎节段矢状面弯曲幅度值之间存在关联。还确定了疼痛的其他决定因素。
在人体工程学潜力较高和较低的工作站工作的受试者中，均观察到工作参数超标。从事坐姿工作的人的工作姿势仅在其外部特征上相似。疼痛取决于工作姿势。疼痛强度由其他因素决定：专业经验时长、疼痛持续时间、每周工作小时数、体重指数（BMI）。《医学实践》2018年；69(5):509 - 522。
