The assessment of cervical spine kinematic axial rotation performance is of great importance in the context of the study of neck sensorimotor control. However, studies addressing the influence of the level of provocation of spinal pain and the potential benefit of passive manual therapy mobilizations in patients with acute-subacute non-specific neck pain are lacking.
A non-randomized prospective clinical trial with an intervention design was conducted. We investigated: (1) the test-retest reliability of kinematic variables during a fast axial head rotation task standardized with the DidRen laser test device in 42 Healthy pain-free Control Participants (HCP) (24.3 years ±6.8); (2) the differences in kinematic variables between HCP and 38 patients with Acute-subacute Non-Specific neck Pain (ANSP) assigned to two different groups according to whether their pain was localized in the upper or lower spine (46.2 years ±16.3); and (3) the effect of passive manual therapy mobilizations on kinematic variables of the neck during fast axial head rotation.
(1) Intra-class correlation coefficients ranged from moderate (0.57 (0.06-0.80)) to excellent (0.96 (0.91-0.98)). (2) Kinematic performance during fast axial rotations of the head was significantly altered in ANSP compared to HCP (age-adjusted) for one variable: the time between peaks of acceleration and deceleration (p<0.019). No significant difference was observed between ANSP with upper vs lower spinal pain localization. (3) After the intervention, there was a significant effect on several kinematic variables, e.g., ANSP improved peak speed (p<0.007) and performance of the DidRen laser test (p<0.001), with effect sizes ranging from small to medium.
(1) The DidRen laser test is reliable. (2) A significant reduction in time between acceleration and deceleration peaks was observed in ANSP compared to HCP, but with no significant effect of spinal pain location on kinematic variables was found. (3) We found that neck pain decreased after passive manual therapy mobilizations with improvements of several kinematic variables.

颈椎运动轴向旋转性能的评估在颈部感觉运动控制研究中非常重要。然而，目前缺乏关于脊柱疼痛激发程度以及被动手法治疗松动术对急性亚急性非特异性颈痛患者的潜在益处的研究。
采用非随机前瞻性临床试验设计，对 42 名健康无痛对照组参与者（HCP）（24.3 岁±6.8 岁）进行快速轴向头部旋转任务中运动学变量的测试-再测试可靠性研究，采用 DidRen 激光测试设备进行标准化；对 38 名急性亚急性非特异性颈痛（ANSP）患者根据疼痛定位在上段脊柱还是下段脊柱进行分组，对 HCP 和这两组患者的运动学变量进行差异比较；观察被动手法治疗松动术对快速轴向头部旋转时颈部运动学变量的影响。
（1）组内相关系数范围为中度（0.57（0.06-0.80））至优秀（0.96（0.91-0.98））。（2）与 HCP（年龄调整后）相比，ANSP 患者在快速轴向头部旋转时的运动表现明显改变，一个变量为加速度和减速峰值之间的时间（p<0.019）。在上段脊柱疼痛与下段脊柱疼痛定位的 ANSP 患者之间未观察到显著差异。（3）干预后，几个运动学变量的变化具有统计学意义，例如，ANSP 患者的峰值速度（p<0.007）和 DidRen 激光测试表现（p<0.001）显著提高，效应大小为小到中。
（1）DidRen 激光测试可靠。（2）与 HCP 相比，ANSP 患者在加速度和减速峰值之间的时间明显减少，但脊柱疼痛位置对运动学变量没有显著影响。（3）我们发现，被动手法治疗松动术可降低颈部疼痛，并改善几个运动学变量。
