In a patient with a potential cervical spine injury, minimizing or eliminating movement at the head and neck during stabilization and transport is paramount because movement can exacerbate the condition. Any equipment or technique creating less movement will allow for a more effective and safe stabilization of an injured patient, reducing the likelihood of movement and potential secondary injury.
To compare the amount of head movement created during the log-roll and motorized spine-board (MSB) stabilization techniques.
A 2-condition, repeated-measures design.
Laboratory.
Thirteen certified athletic trainers, emergency first responders, and emergency medical technicians (6 men, 7 women).
INTERVENTION(S): Subjects rotated through 4 positions for the log roll and 2 positions for the MSB. Each subject performed 3 trials while maintaining manual, inline stabilization of the model's head for each condition.
MAIN OUTCOME MEASURE(S): Three-dimensional head movement was measured and expressed as degrees of motion.
The log roll created significantly more motion in the frontal and transverse planes compared with the MSB (P = .001 for both measures). No significant difference was noted for sagittal-plane motion (P = .028).
The MSB created less movement at the head than did the log roll in 2 planes of motion and created slightly more motion in 1 plane, although this difference was not significant. The MSB may provide emergency responders with an appropriate alternative method for stabilizing and transporting a supine injured athlete without requiring a log roll.
对于疑似颈椎损伤的患者，在固定和转运过程中尽量减少或消除头部和颈部的移动至关重要，因为移动会加重病情。任何产生更少移动的设备或技术都能更有效地安全固定受伤患者，降低移动和潜在二次损伤的可能性。
比较在滚动法和电动脊柱板（MSB）固定技术过程中产生的头部移动量。
两条件重复测量设计。
实验室。
13名认证的运动训练师、急救人员和急诊医疗技术人员（6名男性，7名女性）。
受试者在滚动法中变换4个姿势，在MSB固定中变换2个姿势。每种情况下，每位受试者在保持对模型头部手动、轴向固定的同时进行3次试验。
测量三维头部移动并以运动度数表示。
与MSB相比，滚动法在额面和横面产生的移动明显更多（两项测量P值均为0.001）。矢状面移动无显著差异（P = 0.028）。
在两个运动平面上，MSB产生的头部移动比滚动法少，在一个平面上产生的移动略多，尽管这种差异不显著。MSB可为急救人员提供一种合适的替代方法，用于固定和转运仰卧位受伤运动员，而无需采用滚动法。
