Abstract

Background Neck pain is a common complaint worldwide and ranked seventh in 2010 as the cause of ‘years lived with disability’ in Ghana. Proprioceptive dysfunction, measured by joint position error (JPE) tests, indicates an association with neck pain frequency, dizziness and balance problems in patients. Objectives To examine proprioceptive deficits of the neck using a laser pointer attached to the head. Methods Twenty patients within the age group 21–60 years, with at least five points on the neck disability index (NDI), and 20 age- and sex-matched controls with less than five points on the NDI were recruited for this study. The JPE was determined wearing a headlight laser pointer directed towards a Cartesian coordinate system adjusted to x/y = 0/0, placed on a wall after returning from left and right rotation, flexion and extension. From starting in an upright sitting position, facing the Cartesian coordinate system, each participant performed five repetitions for each movement direction. The mean of five repetitions for each movement direction was calculated as absolute error (AE), constant error (CE) and variable error (VE). Results Control participants showed larger JPE values for nearly all AE, CE and VE. After repositioning from flexion controls showed an approximately 0.6 ° larger median JPE, and the opposite for extension, with median differences between 1 ° and 2 °. Conclusion The results of this study do not reveal any meaningful differences between patients with mild disabled neck movement compared with controls. Clinical implications Joint position error testing does not seem useful for patients with mild neck disability.
非特异性颈部疾病患者和无症状年龄匹配个体的关节位置误差比较
颈痛是世界范围内的一种常见疾病,在2010年加纳的“残疾生活年数”中排名第七。本体感觉功能障碍,通过关节位置误差(JPE)测试来测量,表明与患者颈部疼痛频率、头晕和平衡问题有关。目的应用头部激光笔检查颈部本体感觉缺损。方法选取年龄在21 ~ 60岁、颈部残疾指数(NDI)≥5分的患者20例,以及年龄和性别匹配且NDI≤5分的对照组20例。JPE是戴着一个头灯激光笔确定的,指向一个调整为x/y = 0/0的笛卡尔坐标系,在左右旋转、弯曲和伸展返回后放置在墙上。从直立坐姿开始,面对笛卡尔坐标系,每个参与者在每个运动方向上重复五次。每个运动方向5次重复的平均值计算为绝对误差(AE)、恒定误差(CE)和可变误差(VE)。结果对照组几乎所有AE、CE和VE的JPE值都较大。屈曲对照组复位后,中位JPE增大约0.6°,伸直组则相反,中位差异在1°和2°之间。结论本研究结果未显示轻度颈部运动障碍患者与对照组相比有任何显著差异。临床意义关节位置误差测试似乎对轻度颈部残疾患者没有用处。
