Although impaired neck proprioception has been demonstrated in patients with chronic neck pain, previous studies have not consistently shown any association between pain intensity and proprioceptive performance. We therefore investigated whether temporal aspects of pain are associated with cervicocephalic kinesthetic sensibility. One hundred and twenty-seven adults with or without subclinical neck pain undertook two tasks, repositioning their heads to the neutral head position (head-to-NHP) and target position (head-to-target) in sagittal and transverse plane. Absolute error was calculated from position data recorded by an ultrasound-based motion analysis system. Pain frequency, duration, and intensity were evaluated using a questionnaire. A mixed effects model was constructed to test the effect on reposition error by different pain factors, with age, gender and maximal cervical range of motion as covariates. A higher pain frequency was associated with greater reposition errors for all movement directions in the head-to-NHP task. No consistent effect was observed for pain intensity or duration. In the case of the head-to-target task, no consistent effect was observed for any of the three pain factors. The findings reveal that pain frequency, not the intensity or duration of pain, is associated with neck proprioception in individuals with subclinical neck pain.
尽管在慢性颈部疼痛患者中已证实存在颈部本体感觉受损，但先前的研究并未始终表明疼痛强度与本体感觉表现之间存在任何关联。因此，我们调查了疼痛的时间因素是否与颈脑动觉敏感性相关。127名有或无亚临床颈部疼痛的成年人进行了两项任务，即将头部重新定位到矢状面和横断面的中立头部位置（头部至中立位）和目标位置（头部至目标位）。根据基于超声的运动分析系统记录的位置数据计算绝对误差。使用问卷评估疼痛频率、持续时间和强度。构建了一个混合效应模型，以测试不同疼痛因素对重新定位误差的影响，并将年龄、性别和最大颈椎活动范围作为协变量。在头部至中立位任务中，较高的疼痛频率与所有运动方向上更大的重新定位误差相关。未观察到疼痛强度或持续时间的一致影响。在头部至目标位任务中，未观察到这三个疼痛因素中的任何一个产生一致影响。研究结果表明，在有亚临床颈部疼痛的个体中，与颈部本体感觉相关的是疼痛频率，而非疼痛强度或持续时间。
