Sensory reweighting of postural control was compared in participants with and without neck pain. Center of pressure variables of 60 volunteers, the same in each group, were calculated under four standing conditions: (a) eyes open, neutral head posture; (b) foam interface, eyes open; (c) cervical extension, eyes open; and (d) cervical extension, eyes closed. All center of pressure variables except anterior posterior range/velocity increased significantly in Condition 2 compared with Conditions 1 and 3 (p < .001) and in Condition 4 compared with Conditions 1 and 3. The mediolateral range/velocity and path length in both groups, anterior posterior range in patients, and center of pressure area in the control group were significantly different between Conditions 2 and 4 (p < .001). No overweighting was observed on the vestibular or visual afferents in patients. Compensatory strategies seem to lie within the proprioceptive system.
对有和无颈部疼痛的参与者进行姿势控制的感觉重新加权比较。在四种站立条件下计算了 60 名志愿者（每组相同）的压力中心点变量：（a）睁眼，中立头部姿势；（b）泡沫界面，睁眼；（c）颈椎伸展，睁眼；和（d）颈椎伸展，闭眼。与条件 1 和 3 相比，条件 2 中的所有压力中心点变量（除前后范围/速度外）均显著增加（p<.001），与条件 1 和 3 相比，条件 4 中的所有压力中心点变量均显著增加（p<.001）。两组的前后范围/速度和路径长度、患者的前后范围以及对照组的压力中心点面积在条件 2 和 4 之间存在显著差异（p<.001）。在患者中未观察到对前庭或视觉传入的过度加权。补偿策略似乎位于本体感受系统内。
