Neck movement is important for many activities of daily living (ADL). Neck disorders, such as cervical spondylosis and whiplash can limit neck movement and ADL. The cervical range of motion (CROM) device has been recently used to measure neck range of motion (ROM); however, this measurement includes trunk motion, and therefore does not represent a pure neck ROM measurement. The authors aimed to develop a new method to establish pure neck ROM measurements during flexion, extension, lateral bending, and rotation using a three-dimensional motion analysis system, VICON.
Twelve healthy participants were recruited and neck ROMs during flexion, extension, lateral bending, and rotation were measured using VICON and the CROM device. Test-retest repeatability was assessed using interclass correlation coefficients (ICCs), standard error of measurement (SEM), and minimal detectable change (MDC). Validity between two measurements was evaluated using a determination coefficient and Pearson's correlation coefficient.
ICCs of neck ROM measured using VICON and the CROM device were all at substantial or almost perfect levels [VICON: ICC(1,2) = 0.786-0.962, the CROM device: ICC(1,2) = 0.736-0.950]. Both SEMs and MDCs were low in all measurement directions (VICON: SEM = 1.3°-4.5°, MDC = 3.6°-12.5°; the CROM device: SEM = 2.2°-3.9°, MDC = 6.1°-10.7°). Determination coefficients (R(2)s) and Pearson's correlation coefficients (rs) between the two measurement methods were high (R(2) = 0.607-0.745, r = 0.779-0.863).
VICON is a useful system to measure neck ROMs and evaluate the efficacy of interventions, such as surgery or physiotherapeutic exercise.
颈部活动对许多日常生活活动（ADL）都很重要。颈部疾病，如颈椎病和挥鞭伤，会限制颈部活动和日常生活活动。颈椎活动度（CROM）测量仪最近被用于测量颈部活动度（ROM）；然而，这种测量包括了躯干运动，因此并不代表纯粹的颈部ROM测量。作者旨在开发一种新方法，使用三维运动分析系统VICON在屈曲、伸展、侧屈和旋转过程中建立纯粹的颈部ROM测量。
招募了12名健康参与者，使用VICON和CROM测量仪测量其在屈曲、伸展、侧屈和旋转过程中的颈部ROM。使用组内相关系数（ICC）、测量标准误差（SEM）和最小可检测变化（MDC）评估重测重复性。使用决定系数和皮尔逊相关系数评估两种测量之间的效度。
使用VICON和CROM测量仪测量的颈部ROM的ICC均处于实质或几乎完美水平[VICON：ICC(1,2)=0.786 - 0.962，CROM测量仪：ICC(1,2)=0.736 - 0.950]。在所有测量方向上，SEM和MDC都很低（VICON：SEM = 1.3° - 4.5°，MDC = 3.6° - 12.5°；CROM测量仪：SEM = 2.2° - 3.9°，MDC = 6.1° - 10.7°）。两种测量方法之间的决定系数（R(2)）和皮尔逊相关系数（r）都很高（R(2)=0.607 - 0.745，r = 0.779 - 0.863）。
VICON是一种用于测量颈部ROM和评估手术或物理治疗运动等干预效果的有用系统。
