Repositioning of residents often require forward bending awkward postures, which can lead to low back pain. As a result, interventions that provide training in ergonomic principles are crucial to minimize work-related strain on the lower back. This RCT investigated the effects of tailored ergonomics training on nurses' movement behavior, upper body flexion, lateral flexion and rotation during repositioning. n = 35 nurses participated (intervention group: n = 15, control group: n = 20). Data were collected at baseline and at ten weeks (movement observation sheet, 3D motion capturing (Xsens)). The analysis included one-way and repeated measures ANOVA, and statistical parametric mapping with Hotellings T2 test. The intervention group showed improved feet position during turning and lowering the person, and reduced upper body angles in flexion, and rotation. No significant differences in upper body posture were observed over time during the repositioning task. These findings are crucial for developing recommendations that help ensure ergonomics training remains within safe limits.
