A repeated-measures design using a cadaveric model was used in this preliminary investigation on the effectiveness of spine-board transfer techniques.
To compare the amount of angulation (flexion-extension) motion that results at the cervical spine during the execution of the log-roll maneuver and the lift-and-slide technique; and to examine how changes to the integrity of the cervical spine impacts the amount of motion generated during the transfer process.
Very little research has been performed to establish the efficacy of spine-board transfer techniques. Early studies have indicated that the log-roll maneuver may not be appropriate for transferring victims with thoracolumbar injuries. Also, there has not been a single study that has reported the impact of transfer techniques on the unstable cervical spine. This lack of data necessitated the present study.
Four groups (with six participants each) were asked to execute the log-roll maneuver and the lift-and-slide technique on five cadavers. An electromagnetic motion analysis device was used to assess the amount of angulation motion generated at the C5-C6 segment during the execution of these transfer techniques. To examine how changes to the integrity of the cervical spine impacts the amount of motion that is produced during the transfer process, flexion-extension motion was assessed under various conditions: across a stable C5-C6 segment, after the creation of a posterior ligamentous injury, and after a complete segmental injury.
No significant differences in angulation motion were noted between transfer techniques. However, significant differences were noted between all three injury conditions. That is, as the severity of the injury increased, the average amount of angulation motion produced at the site of the lesion also increased, regardless of technique.
The participants of this study were able to restrict flexion-extension motion equally well with thelog-roll maneuver as with the lift-and-slide technique. However, more research is needed to fully ascertain the effectiveness of spine-board transfer techniques.
在这项关于脊柱板转移技术有效性的初步调查中，采用了使用尸体模型的重复测量设计。
比较在实施滚木式搬运操作和抬移技术时颈椎产生的成角（屈伸）运动量；并研究颈椎完整性的变化如何影响转移过程中产生的运动量。
为确定脊柱板转移技术的有效性所做的研究非常少。早期研究表明，滚木式搬运操作可能不适用于搬运胸腰椎损伤的受害者。此外，还没有一项研究报告转移技术对不稳定颈椎的影响。由于缺乏这些数据，才有了本研究。
四组（每组六名参与者）被要求在五具尸体上执行滚木式搬运操作和抬移技术。使用电磁运动分析装置评估在执行这些转移技术时C5-C6节段产生的成角运动量。为研究颈椎完整性的变化如何影响转移过程中产生的运动量，在各种条件下评估屈伸运动：跨越稳定的C5-C6节段、在造成后韧带损伤后以及在完全节段损伤后。
转移技术之间在成角运动方面未发现显著差异。然而，在所有三种损伤情况之间发现了显著差异。也就是说，随着损伤严重程度的增加，无论采用何种技术，损伤部位产生的平均成角运动量也会增加。
本研究的参与者使用滚木式搬运操作和抬移技术在限制屈伸运动方面的效果相当。然而，需要更多研究来全面确定脊柱板转移技术的有效性。
