The prevalence and consequences of musculoskeletal pain is considerable among healthcare workers, allegedly due to high physical work demands of healthcare work. Previous investigations have shown promising results of physical exercise for relieving pain among different occupational groups, but the question remains whether such physical exercise should be performed at the workplace or conducted as home-based exercise. Performing physical exercise at the workplace together with colleagues may be more motivating for some employees and thus increase adherence. On the other hand, physical exercise performed during working hours at the workplace may be costly for the employers in terms of time spend. Thus, it seems relevant to compare the efficacy of workplace- versus home-based training on musculoskeletal pain. This study is intended to investigate the effect of workplace-based versus home-based physical exercise on musculoskeletal pain among healthcare workers.
METHODS/DESIGN: This study was designed as a cluster randomized controlled trial performed at 3 hospitals in Copenhagen, Denmark. Clusters are hospital departments and hospital units. Cluster randomization was chosen to increase adherence and avoid contamination between interventions. Two hundred healthcare workers from 18 departments located at three different hospitals is allocated to 10 weeks of 1) workplace based physical exercise performed during working hours (using kettlebells, elastic bands and exercise balls) for 5 × 10 minutes per week and up to 5 group-based coaching sessions, or 2) home based physical exercise performed during leisure time (using elastic bands and body weight exercises) for 5 × 10 minutes per week. Both intervention groups will also receive ergonomic instructions on patient handling and use of lifting aides etc. Inclusion criteria are female healthcare workers working at a hospital. Average pain intensity (VAS scale 0-10) of the back, neck and shoulder (primary outcome) and physical exertion during work, social capital and work ability (secondary outcomes) is assessed at baseline and 10-week follow-up. Further, postural balance and mechanical muscle function is assessed during clinical examination at baseline and follow-up.
This cluster randomized trial will investigate the change in self-rated average pain intensity in the back, neck and shoulder after either 10 weeks of physical exercise at the workplace or at home.

在医护人员中，肌肉骨骼疼痛的患病率和后果相当可观，据称这是由于医护工作的体力工作要求高所致。以前的研究表明，体育锻炼对缓解不同职业群体的疼痛有可喜的效果，但问题仍然是这种体育锻炼是应该在工作场所进行，还是作为家庭锻炼进行。与同事一起在工作场所进行体育锻炼对某些员工来说可能更有动力，从而提高依从性。另一方面，在工作场所的工作时间内进行体育锻炼可能会给雇主带来时间上的花费。因此，比较工作场所与家庭培训对肌肉骨骼疼痛的效果似乎是相关的。本研究旨在调查工作场所与家庭体育锻炼对医护人员肌肉骨骼疼痛的影响。
方法/设计：这是一项在丹麦哥本哈根的 3 家医院进行的集群随机对照试验。集群是医院科室和医院单位。选择集群随机化是为了提高依从性并避免干预之间的污染。将来自 3 家不同医院的 18 个科室的 200 名医护人员分配到 10 周的 1）工作场所的体育锻炼，在工作时间进行（使用壶铃、弹性带和健身球），每周 5 次，每次 10 分钟，并进行多达 5 次小组辅导，或 2）家庭体育锻炼，在闲暇时间进行（使用弹性带和体重练习），每周 5 次，每次 10 分钟。两个干预组还将接受有关患者搬运和使用提升辅助工具等的人体工程学指导。纳入标准是在医院工作的女性医护人员。在基线和 10 周随访时，评估背部、颈部和肩部的平均疼痛强度（VAS 量表 0-10）（主要结局）和工作时的体力消耗、社会资本和工作能力（次要结局）。此外，在基线和随访时进行临床检查，评估姿势平衡和机械肌肉功能。
这项集群随机试验将调查在工作场所或家中进行 10 周体育锻炼后，自我评估的背部、颈部和肩部平均疼痛强度的变化。
