Cervical range of motion (RoM) has been the subject of many studies. However, only very few of these studies have considered the influence of movement execution speed on the cervical kinematics. The aim of this study is to evaluate the influence of movement speed on cervical RoM.
Cervical RoM was recorded using an optoelectronic system; 32 healthy subjects performed movements in two modes: the best possible and as fast as possible.
The primary movements (flexion-extension, lateral bending, axial rotation) and coupled movements were studied. Paired Student's tests were performed to compare the two modes of movement.
The results showed that cervical RoM differed significantly between movement speeds. Amplitudes were higher for each movement (p < 0.001 for flexion-extension, p < 0.001 for lateral flexion, p = 0.008 for axial rotations) when movements were performed as quickly as possible. The range of movements carried out the best possible reached only 95% of those during movements carried out as fast as possible. Concerning coupled movements, an increase in rotational movements coupled to lateral flexion during fast movements was observed.
The range of motion reported in the literature corresponds to movement carried out in a mode resembling the best possible of our study. Movements made as quickly as possible can display larger motion ranges.
颈椎活动范围（RoM）一直是众多研究的主题。然而，这些研究中只有极少数考虑了运动执行速度对颈椎运动学的影响。本研究的目的是评估运动速度对颈椎RoM的影响。
使用光电系统记录颈椎RoM；32名健康受试者以两种模式进行运动：尽可能好和尽可能快。
研究了主要运动（屈伸、侧屈、轴向旋转）和耦合运动。进行配对学生检验以比较两种运动模式。
结果表明，运动速度不同时颈椎RoM存在显著差异。当尽可能快地进行运动时，每个运动的幅度都更高（屈伸时p < 0.001，侧屈时p < 0.001，轴向旋转时p = 0.008）。尽可能好地进行的运动范围仅达到尽可能快地进行运动时的95%。关于耦合运动，观察到快速运动期间与侧屈耦合的旋转运动增加。
文献中报道的运动范围对应于以类似于我们研究中尽可能好的模式进行的运动。尽可能快地进行的运动可以显示出更大的运动范围。
