The purpose of this pilot study was to evaluate sensorimotor functions in patients with chronic neck pain with objective and quantitative methods. A group of 16 patients with chronic idiopathic neck pain of insidious onset or whiplash associated disorders (WAD) was compared to an equally sized group of healthy subjects. Kinematics were investigated during voluntary head rotations by measuring range of motion, variability of range of motion (ROM-Variability), peak velocity, and smoothness of movement (jerk index). Repositioning acuity after cervical rotations was evaluated by analysing constant and variable error (VE). In comparison to the healthy subjects, the patients showed significantly larger jerk index, ROM-Variability and VE. No statistically significant differences were found between insidious neck pain and WAD. It is concluded that jerky and irregular cervical movements and poor position sense acuity are characteristic sensorimotor symptoms in chronic neck pain. The observed individuality in sensorimotor disturbances emphasizes the importance of developing specific rehabilitation programs for specific dysfunctions, and of using objective and quantitative methods for evaluation of rehabilitation.
这项初步研究的目的是采用客观和定量的方法评估慢性颈部疼痛患者的感觉运动功能。将一组16例隐匿性起病的慢性特发性颈部疼痛或挥鞭样损伤相关疾病（WAD）患者与同等规模的健康受试者组进行比较。通过测量运动范围、运动范围变异性（ROM变异性）、峰值速度和运动平滑度（急动指数）来研究自主头部旋转过程中的运动学。通过分析恒定误差和可变误差（VE）来评估颈椎旋转后的重新定位敏锐度。与健康受试者相比，患者的急动指数、ROM变异性和VE显著更大。隐匿性颈部疼痛和WAD之间未发现统计学上的显著差异。得出的结论是，颈部运动急促且不规则以及位置感觉敏锐度差是慢性颈部疼痛的典型感觉运动症状。在感觉运动障碍中观察到的个体差异强调了针对特定功能障碍制定特定康复计划以及使用客观和定量方法评估康复的重要性。
