Deficits in cervical proprioception have been identified in subjects with neck pain through the measure of head repositioning accuracy (HRA). Nevertheless there appears to be no general consensus regarding the construct of measurement of error used for calculating HRA. This study investigated four different mathematical methods of measurement of error to determine if there were any differences in their ability to discriminate between a control group and subjects with a whiplash associated disorder. The four methods for measuring cervical joint position error were calculated using a previous data set consisting of 50 subjects with whiplash complaining of dizziness (WAD D), 50 subjects with whiplash not complaining of dizziness (WAD ND) and 50 control subjects. The results indicated that no one measure of HRA uniquely detected or defined the differences between the whiplash and control groups. Constant error (CE) was significantly different between the whiplash and control groups from extension (p<0.05). Absolute errors (AEs) and root mean square errors (RMSEs) demonstrated differences between the two WAD groups in rotation trials (p<0.05). No differences were seen with variable error (VE). The results suggest that a combination of AE (or RMSE) and CE are probably the most suitable measures for analysis of HRA.
通过测量头部重新定位准确性（HRA），已在颈部疼痛患者中发现颈椎本体感觉缺陷。然而，对于用于计算HRA的误差测量结构似乎没有普遍共识。本研究调查了四种不同的误差测量数学方法，以确定它们在区分对照组和挥鞭样相关障碍患者方面的能力是否存在差异。使用先前的数据集计算测量颈椎关节位置误差的四种方法，该数据集包括50名抱怨头晕的挥鞭样损伤患者（WAD D）、50名未抱怨头晕的挥鞭样损伤患者（WAD ND）和50名对照受试者。结果表明，没有一种HRA测量方法能唯一检测或定义挥鞭样损伤组和对照组之间的差异。在伸展时，挥鞭样损伤组和对照组之间的恒定误差（CE）有显著差异（p<0.05）。在旋转试验中，绝对误差（AE）和均方根误差（RMSE）显示两个WAD组之间存在差异（p<0.05）。在可变误差（VE）方面未发现差异。结果表明，AE（或RMSE）和CE的组合可能是分析HRA最合适的测量方法。
