. This study investigated the effectiveness of a workplace-based multifaceted intervention to manage musculoskeletal disorders (MSDs) and their consequences in the workers of a medium-sized company. . A program consisting of participatory ergonomics (PE), workplace exercises (WE) and acupuncture as the main resources of physical therapy (PT) performed at the workstations was conducted for 22 months with 126 workers. The outcomes were complaints of MSDs and absenteeism measured by the Nordic musculoskeletal questionnaire. We also measured workers' perceptions about the intervention using a Likert-based questionnaire. . The rate of MSDs was significantly reduced in at least one body region ( = 0.001). Absenteeism was also significantly reduced ( = 0.020). For workers with pain at baseline, at least 40% improved totally, while for others the duration, frequency and intensity of pain was reduced for all body regions, except for the lower back and fingers. For workers without pain at baseline, a 70% target for prevention of MSDs was achieved. Most workers (56-99%) agreed that the intervention improved the consequences of MSDs. . A multifaceted intervention consisting of PE, WE and acupuncture as the main resources of PT performed at the workstations may be relevant to managing MSDs in working populations.
. 本研究旨在调查一种基于工作场所的多方面干预措施对中型公司员工肌肉骨骼疾病（MSD）及其后果的管理效果。. 该干预措施由参与式人体工程学（PE）、工作场所锻炼（WE）和针灸作为主要物理治疗（PT）资源组成，在 126 名员工中进行了 22 个月。通过北欧肌肉骨骼问卷测量 MSD 投诉和缺勤率作为结果。我们还使用基于李克特量表的问卷测量了员工对干预措施的看法。. MSD 发生率在至少一个身体部位显著降低（=0.001）。缺勤率也显著降低（=0.020）。对于基线时有疼痛的工人，至少有 40%的人完全改善，而对于其他人，除了下背部和手指外，所有身体部位的疼痛持续时间、频率和强度都有所降低。对于基线时没有疼痛的工人，实现了预防 MSD 的 70%目标。大多数工人（56-99%）认为干预措施改善了 MSD 的后果。. 在工作场所进行的由 PE、WE 和针灸作为主要 PT 资源的多方面干预措施可能与管理工作人群中的 MSD 有关。
