Firefighters and EMS providers continue to be challenged when lifting heavy patients in their homes. This study investigated the biomechanical efficacy of four devices that could be used by two-person teams when lifting patients from the floor, from a reclining chair, or from a Simulated Inflatable Seat at chair height. Fourteen firefighter-paramedics, working in two-person teams, were instrumented with motion capture and electromyographic sensors. The Binder Lift™, the Simple Strap, and the Slip Preventer were used to lift patient actors, and were compared to current lifting methods. Postural data and the peak dynamic spine shear forces at the L5/S1 level were reduced when using the Simple Strap, the Binder Lift, and the Simulated Inflatable Seat. The Slip Preventer reduced spine flexion when the Binder Lift was not used. In summary, the tested devices can potentially reduce the biomechanical loads experienced by EMS providers as they lift and move patients.
消防员和急救医疗服务提供者在搬运家中的重症患者时仍然面临挑战。本研究调查了四种设备的生物力学效果，这些设备可以由两人小组在从地板上、从倾斜的椅子上或从模拟充气座椅（高度与椅子相当）上抬起患者时使用。14 名消防护理人员组成两人小组，配备了运动捕捉和肌电图传感器。使用 Binder Lift™、Simple Strap 和 Slip Preventer 来抬起患者扮演者，并与当前的提升方法进行了比较。使用 Simple Strap、Binder Lift 和模拟充气座椅可以降低姿势数据和 L5/S1 水平的峰值动态脊柱剪切力。当不使用 Binder Lift 时，Slip Preventer 可减少脊柱弯曲。总之，这些测试设备可以降低急救医疗服务提供者在搬运和移动患者时所承受的生物力学负荷。
