Background

Cervical collar treatment is widespread amongst a broad range of ages and conditions. However, these devices are associated with a known correlation between collar usage and adverse effects such as pressure ulcers, infections, exacerbated spinal injury, and higher morbidity. The objective of this study was to determine if the ability of a newly developed DJO Procare XTEND 174 collar to restrict cervical spine motion was similar to that of the previously studied Össur Miami J collar and to determine if this was done while producing similar tissue interface pressures.

Methods

Three-dimensional kinematic data were obtained for twelve healthy volunteer participants (6 female, 6 male) using a 10-camera infrared motion capture system. Cervical range of motion in each plane was calculated using angles between head and thorax rigid-body axes. Tissue interface pressure was measured between the head and the collar with three flexible pressure sensor pads over the anterior mandibles and occiput. The distribution of interface pressures was obtained in both the seated and supine positions.

Findings

Both collars significantly restricted range of motion in all movement directions (p < 0.001) compared to no collar. There were no significant differences in restrictiveness nor in tissue interface pressures between the collars. Both collars exhibited similar range of motion restriction and similar interface pressures.

Interpretation

Our data indicate that the newly developed Procare XTEND 174 collar is not statistically different from the scientifically recognized Miami J benchmark collar regarding cervical range of motion restriction in all three planes and tissue interface pressure.

背景

颈托治疗在广泛的年龄和条件下很普遍。然而，这些装置与项圈的使用与诸如压疮、感染、加剧的脊柱损伤和更高的发病率等不利影响之间的已知相关性有关。本研究的目的是确定新开发的 DJO Procare XTEND 174 项圈限制颈椎运动的能力是否与先前研究的 Össur Miami J 项圈相似，并确定是否在产生相似组织界面压力的同时进行.

方法

使用 10 摄像头红外动作捕捉系统为 12 名健康志愿者参与者（6 名女性，6 名男性）获得了三维运动学数据。使用头部和胸部刚体轴之间的角度计算每个平面中的颈椎活动范围。用三个柔性压力传感器垫在前颌骨和枕骨上测量头部和项圈之间的组织界面压力。在坐姿和仰卧位都获得了界面压力的分布。

发现

 与没有项圈相比，两个项圈都显着限制了所有运动方向的运动范围 ( p < 0.001)。项圈之间的限制性和组织界面压力没有显着差异。两个项圈都表现出相似的运动限制范围和相似的界面压力。

解释

我们的数据表明，新开发的 Procare XTEND 174 项圈与科学认可的 Miami J 基准项圈在所有三个平面和组织界面压力的颈椎活动范围限制方面没有统计学差异。
