The aim of an ergonomics intervention conducted in the tire manufacturing industry was to improve working conditions. Before the start, a senior manager supported the intervention. Participants were divided into teams and trained. After observing the overall performance of the teams, over 100 improvements were successfully implemented. After the improvements, there were statistically significant differences in annual and weekly prevalence of, and annual disability reported for, the upper back, the lower back, knees and wrists between before and after intervention. The annual prevalence of upper back, lower back, knee and wrist complaints decreased from, respectively, 60.3%, 50.2%, 28.9%, 25.8% before the intervention to 31.3%, 35.9%, 17.1%, 20.7% after the intervention. Significant factors were training and supportive environment based on full commitment of the top management.
本研究旨在改善轮胎制造业的工作条件。在干预开始前，一名高级经理对此表示支持。参与者被分成小组并接受培训。在观察了团队的整体表现后，成功实施了 100 多项改进措施。改进后，干预前后上背部、下背部、膝盖和手腕的年度和周度患病率以及年度残疾报告有统计学意义。上背部、下背部、膝盖和手腕的年度患病率分别从干预前的 60.3%、50.2%、28.9%和 25.8%下降到干预后的 31.3%、35.9%、17.1%和 20.7%。这些显著的改善因素包括培训和支持性环境，这得益于高层管理人员的全力支持。
