导读：卫生保健工作者在处理导致该人群普遍腰痛的患者时，需要从事重复性的动作。许多变量与腰痛有关，包括重复运动和异常多裂肌大小和激活。本研究旨在观察医护人员腰痛与三个变量之间的关系：促进患者时的峰值腰背力、多裂肌横截面积和多裂肌激活。材料和方法：这项横断面相关研究包括35名目前在住院医院、急症医院或熟练护理机构工作的医护人员，他们的工作是处理病人。通过运动捕捉和地面力板收集力和运动数据，并进行处理以估计低背力。超声测量多裂肌横截面积，表面肌电图测量激活度。结果：疼痛组与非疼痛组腰背力峰值差异无统计学意义。在测量的3个水平中的2个水平（L5和S1），多裂肌横截面积有显著差异。最后，多裂肌的激活没有显著差异。结论：在病人处理和腰椎多裂肌激活时的峰值下背力似乎不是医护人员疼痛的一个因素。在这一人群中，多裂肌的横截面积与疼痛相关，表明较小的多裂肌可能增加疼痛的可能性。应该做进一步的工作来证实这一发现并提供潜在的解决方案。与行业的相关性：发现的因素和方法，以减轻腰痛的医护人员是至关重要的，这些专业人员在各自的职业生涯的寿命。
Introduction: Healthcare workers are required to engage in repetitive actions when handling patients which leads to widespread low back pain in this population. Many variables are related to low back pain including repetitive motions and abnormal multifidus size and activation. This research sought to observe the relationship between low back pain and three variables in healthcare workers specifically: peak low back force when boosting a patient, multifidus cross-sectional area, and multifidus activation. Materials and methods: This cross-sectional, correlational study included 35 healthcare workers who currently work in inpatient hospital, acute hospital, or skilled nursing settings, and engage in patient handling as part of their job. Force and motion data were collected with motion capture and in-ground force plates and processed to estimate low back forces. Multifidus cross-sectional area was measured with ultrasound while activation was measured using surface electromyography. Results: There was not a significant difference in peak low back force between pain and nonpain groups. There was a significant difference in multifidus cross-sectional area at 2 of the 3 levels measured (L5 and S1). Lastly, there was not a significant difference in multifidus activation. Conclusions: Peak low back force during patient handling and lumbar multifidus activation do not seem to be a factor in pain in healthcare workers. Multifidus cross-sectional area is correlated with pain in this population indicating smaller multifidus may increase the likelihood of experiencing pain. Further work should be done to confirm this finding and offer potential solutions. Relevance to industry: Discovering factors in and ways to alleviate low back pain in healthcare workers is essential to the longevity of these professionals in their respective careers.
