Abstract：
Postural sway has not been investigated before or after a neck exercise intervention in individuals with chronic whiplash-associated disorders (WAD). The aim of the study was to investigate postural sway in individuals with chronic WAD grades 2 and 3: (a) compared with healthy matched controls at baseline; (b) after three months of neck-specific exercise and (c) to investigate the correlation between postural sway with self-reported dizziness during motion and balance problems/unsteadiness. This is a longitudinal prospective experimental case-control intervention study. Individuals with WAD (n = 30) and age- and gender-matched healthy volunteers (n = 30) participated. Postural sway was assessed using an iPhone application. Measurements were carried out at baseline, and for those with WAD a second measurement was performed at the three-month follow-up when neck-specific exercise intervention ended. The WAD group performed significantly worse than the healthy group in both pathway and ellipse area double stance eyes closed at baseline (main outcome), but not at the three-month follow-up. The WAD group significantly improved after rehabilitation in both pathway double stance eyes closed and pathway single stance eyes open. The correlation between postural sway and self-rated dizziness during motion and balance problems was low to moderate. One may conclude that postural sway was improved after a neck-specific exercise programme. The study results strengthen earlier findings that individuals with WAD have worse balance outcome when they have to rely on neck proprioception (eyes closed). The study results may be important for the development of improved rehabilitation methods for WAD.
摘要：
在患有慢性鞭打相关疾病（WAD）的患者进行颈部运动干预之前或之后，尚未研究姿势摇摆。该研究的目的是调查患有慢性WAD2级和3级的个体的姿势摇摆：（a）与基线时健康匹配的对照组进行比较；（b）进行颈部特定运动三个月后，以及（c）调查姿势摇摆与运动过程中自我报告的头晕和平衡问题/不稳定之间的相关性。这是一项纵向前瞻性实验病例对照干预研究。WAD患者（n=30）和年龄和性别匹配的健康志愿者（n=30）参加。使用iPhone应用程序评估姿势摇摆。在基线进行测量，对于WAD患者,在颈部特定运动干预结束后的3个月随访时进行第二次测量.WAD组在基线时闭眼（主要结果）的途径和椭圆面积双姿态明显差于健康组，但不是在三个月的随访中。WAD组康复后在双路双位眼闭及单路双位眼睁开均有显著进步。在运动和平衡问题期间，姿势摇摆与自我评估的头晕之间的相关性低至中等。可以得出结论，在进行针对颈部的锻炼计划后，姿势摇摆得到了改善。研究结果加强了早期的发现，即WAD患者在不得不依靠颈部本体感觉（闭眼）时，平衡结果较差。研究结果可能对WAD改善康复方法的发展很重要。
