To determine if measures of cervical kinematics are altered in people with acute whiplash associated disorders (WAD) and secondarily, to examine whether kinematic variables are associated with self-reported outcomes.
We recruited people with acute WAD within 15 days after a motor vehicle collision and asymptomatic control participants. All participants performed active neck movements at a self-determined velocity. Maximal range of motion (ROM), peak and mean velocity of movement, smoothness of movement, and cervical joint position error were assessed. Moreover, self-reported measures of perceived pain and disability, pain catastrophising, and fear of movement were obtained.
Sixty people participated: 18 with acute WAD (mean age [SD] 38.7 [12.0]) and 42 as asymptomatic controls (mean age [SD] 38.4 [10.2]). Participants with acute WAD showed significantly decreased ROM in all movement directions (p < 0.0001). All participants with acute WAD showed a reduction in the mean and peak velocity of movement in all directions (p < 0.0001) and the number of velocity peaks was significantly higher (i.e., reduced smoothness of movement) in those with acute WAD in all directions (p < 0.0001). Repositioning acuity following cervical rotation was not significantly different between groups. Neck pain-related disability showed the largest number of significant associations with kinematic features, while fear of movement was not associated with measures of cervical kinematics.
Participants with acute WAD presented with altered cervical kinematics compared to asymptomatic participants. Several measures of cervical kinematics were associated with the level of pain and disability in people with acute WAD but not their fear of movement.
确定急性挥鞭样损伤相关疾病（WAD）患者的颈椎运动学指标是否发生改变，其次，检查运动学变量是否与自我报告的结果相关。
我们招募了机动车碰撞后15天内的急性WAD患者和无症状对照参与者。所有参与者以自行确定的速度进行主动颈部运动。评估最大运动范围（ROM）、运动的峰值和平均速度、运动的平滑度以及颈椎关节位置误差。此外，还获得了自我报告的疼痛和残疾感知、疼痛灾难化以及运动恐惧的测量值。
60人参与研究：18例急性WAD患者（平均年龄[标准差]38.7[12.0]）和42例无症状对照者（平均年龄[标准差]38.4[10.2]）。急性WAD患者在所有运动方向上的ROM均显著降低（p<0.0001）。所有急性WAD患者在所有方向上的运动平均速度和峰值速度均降低（p<0.0001），并且急性WAD患者在所有方向上的速度峰值数量显著更高（即运动平滑度降低）（p<0.0001）。两组之间颈椎旋转后的重新定位敏锐度无显著差异。颈部疼痛相关残疾与运动学特征的显著关联最多，而运动恐惧与颈椎运动学指标无关。
与无症状参与者相比，急性WAD患者的颈椎运动学发生了改变。颈椎运动学的几个指标与急性WAD患者的疼痛和残疾程度相关，但与他们的运动恐惧无关。
