调查的目的是比较有和没有职业颈肱疾病的牙医在颈部和肩部的活动能力和肩部肌肉的静态耐力方面的差异。此外，在一个刺激的情况下，工作位置和任务表现的差异进行了分析。调查是在对Malmöhus区和Malmö市公共牙科服务的143名牙科人员的工作场所进行访问期间进行的。在这些牙医中，96人有颈臂疾病和不适的迹象，而47人没有。人体工程学检查显示，无疼痛症状的牙医在患者背部上半部分下使用楔形垫以获得最佳视野的比例明显高于无疼痛症状的牙医（p < 0.05）。研究还发现，与有疼痛和不适的牙医相比，没有症状的牙医明显更多地意识到并利用了工作中自然产生的停顿。与无症状的牙医相比，有颈肱疾病的牙医保持头部偏侧和旋转的程度更大（p < 0.01）。两组患者在颈部和肩部活动度方面无显著差异。在有和没有颈-肱系统的女性之间发现了显著的差异。
The aim of the investigation was to compare dentists with and without occupational cervicobrachial disorders with regard to the mobility of the neck and shoulders and the static endurance of the shoulder muscles. Further, differences in working position and the task performance on a stimulated case were to be analysed. The investigation was carried out during a visit to the workplace of 143 dental officers in the Public Dental Service in Malmöhus District and the Municipality of Malmö. Of these dentists, 96 had signs of cervico-brachial disorders and discomfort while 47 had not. The ergonomic examination showed, that significantly more dentists without symptoms of pain applied a wedge cushion under the upper part of the back of the patient to get an optimum view (p less than 0.05). It was also found that significantly more dentists without symptoms were aware of and utilised the naturally arising pauses in their work than dentists with pain and discomfort. Further dentists with cervico-brachial disorders kept their head sidebent and rotated to a greater extent than dentists without symptoms (p less than 0.01). No significant difference was found between the two groups concerning mobility of the neck and shoulders. Significant differences were found between women with and without cervico-brachial systems.
