Purpose: The purpose of the study was to contribute to the prevention of musculoskeletal disorders (MSDs) in 119 emergency medical technicians (EMTs) by evaluating ergonomic risk factors of patient lifting work-postures.
Methods: Four procedures were evaluated: using long back-board (LBB) on the sitting and standing main stretcher, using variable stretcher on the sitting and standing main stretcher. Wok-postures were assessed during training.
Results: In using LBB on the sitting main stretcher, the OWAS-score was Mode:3 (Mean:2.30, Maximum:3), the REBA-score was Mode:9 (Mean:7.61, Maximum:11), requiring improvement soon. In using LBB on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.33, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:6 (Mean:5.44, Maximum:11), requiring improvement. In using variable stretcher on the sitting main stretcher, the OWAS-score was Mode:1 (Mean:1.85, Maximum:3), not requiring corrective action, the REBA-score was Mode:6 (Mean:6.78, Maximum:11), requiring improvement. In using variable stretcher on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.84, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:11 (Mean:9.38, Maximum:11), requiring immediate improvement.
Conclusion: All four-procedures showed improvement in work-posture. Thereby, required attention and management in training, occupational health professionals should participate in change of lifting-method, and programs aimed at preventing MSDs should be developed and implemented in fire-academy and fire-station.
