Abstract This study utilised a cross-sectional design to perform measurements of muscle activity as well as forward - and lateral trunk inclination angle during a full workday among 52 female healthcare workers from 16 different departments at five Danish hospitals. Using linear mixed models, the 95th percentile ranks of the normalised root mean square (nRMS) values were analysed for the different types of assistive devices. Compared to no assistive device (mean nRMS 27.9%, 95% CI 24.8%–31.0%), the use of intelligent beds (23.9%, CI 20.2%–27.6%) and ceiling-lifts (24.0%, CI 20.3%–27.7%) led to lower erector spinae nRMS values across all types of patient transfers. Conversely, the use of bedsheets (30.6%, CI 27.1%–34.2%), sliding-sheets (30.3%, CI 26.8%–33.9%) and sliding-boards (33.5%, CI 29.5%–37.6%) were associated with higher levels of erector spinae muscle activity. Consistent use of ceiling-lifts and intelligent beds reduces the physical workload and may thereby decrease the risk of musculoskeletal disorders among healthcare workers. Practioner Summary: Frequent patient transfer is associated with an increased risk of back pain and injury among healthcare workers. This analysis compares the level of physical load during patient transfer with commonly used assistive devices. The results show that use of the ceiling-lift and intelligent bed is associated with relatively low physical load during patient transfer.

使用辅助装置转移患者期间的生物力学负荷:横断面研究

摘要 本研究采用横断面设计,对来自丹麦 5 家医院 16 个不同部门的 52 名女性医护人员在一个完整工作日内进行肌肉活动以及躯干前倾和侧倾角的测量。使用线性混合模型,分析了不同类型辅助设备的归一化均方根 (nRMS) 值的第 95 个百分位等级。与没有辅助设备(平均 nRMS 27.9%,95% CI 24.8%–31.0%)相比,使用智能床(23.9%,CI 20.2%–27.6%)和天花板升降机(24.0%,CI 20.3%–27.7) %) 导致所有类型的患者转移中竖脊肌 nRMS 值降低。相反,使用床单(30.6%,CI 27.1%–34.2%)、滑动床单(30.3%,CI 26.8%–33.9%)和滑板(33.5%,CI 29.5%–37)。6%) 与更高水平的竖脊肌活动相关。持续使用天花板升降机和智能床可以减少体力劳动,从而降低医护人员患肌肉骨骼疾病的风险。实践者总结:频繁的患者转移与医护人员背痛和受伤的风险增加有关。该分析将患者转移期间的身体负荷水平与常用辅助设备进行了比较。结果表明,在患者转移期间,使用吊顶升降机和智能床与相对较低的身体负荷有关。缩写: RMS:均方根;nRMS:归一化均方根;EMG:肌电图;MSD:肌肉骨骼疾病;LBP:腰痛;VAS:视觉模拟量表;MVC:最大自愿收缩 持续使用天花板升降机和智能床可以减少体力劳动,从而降低医护人员患肌肉骨骼疾病的风险。实践者总结:频繁的患者转移与医护人员背痛和受伤的风险增加有关。该分析将患者转移期间的身体负荷水平与常用辅助设备进行了比较。结果表明,在患者转移期间,使用吊顶升降机和智能床与相对较低的身体负荷有关。缩写: RMS:均方根;nRMS:归一化均方根;EMG:肌电图;MSD:肌肉骨骼疾病;LBP:腰痛;VAS:视觉模拟量表;MVC:最大自愿收缩 持续使用天花板升降机和智能床可以减少体力劳动,从而降低医护人员患肌肉骨骼疾病的风险。实践者总结:频繁的患者转移与医护人员背痛和受伤的风险增加有关。该分析将患者转移期间的身体负荷水平与常用辅助设备进行了比较。结果表明,在患者转移期间,使用吊顶升降机和智能床与相对较低的身体负荷有关。缩写: RMS:均方根;nRMS:归一化均方根;EMG:肌电图;MSD:肌肉骨骼疾病;LBP:腰痛;VAS:视觉模拟量表;MVC:最大自愿收缩 频繁的患者转移与医护人员背痛和受伤的风险增加有关。该分析将患者转移期间的身体负荷水平与常用辅助设备进行了比较。结果表明,在患者转移期间,使用吊顶升降机和智能床与相对较低的身体负荷有关。缩写: RMS:均方根;nRMS:归一化均方根;EMG:肌电图;MSD:肌肉骨骼疾病;LBP:腰痛;VAS:视觉模拟量表;MVC:最大自愿收缩 频繁的患者转移与医护人员背痛和受伤的风险增加有关。该分析将患者转移期间的身体负荷水平与常用辅助设备进行了比较。结果表明,在患者转移期间,使用吊顶升降机和智能床与相对较低的身体负荷有关。缩写: RMS:均方根;nRMS:归一化均方根;EMG:肌电图;MSD:肌肉骨骼疾病;LBP:腰痛;VAS:视觉模拟量表;MVC:最大自愿收缩 结果表明,在患者转移期间,使用吊顶升降机和智能床与相对较低的身体负荷有关。缩写: RMS:均方根;nRMS:归一化均方根;EMG:肌电图;MSD:肌肉骨骼疾病;LBP:腰痛;VAS:视觉模拟量表;MVC:最大自愿收缩 结果表明,在患者转移期间,使用吊顶升降机和智能床与相对较低的身体负荷有关。缩写: RMS:均方根;nRMS:归一化均方根;EMG:肌电图;MSD:肌肉骨骼疾病;LBP:腰痛;VAS:视觉模拟量表;MVC:最大自愿收缩
