Past studies examining whether or not cognitive changes actually have occurred as a result of a whiplash (WL) accident have produced varying results. The aim of this study was to identify possible cognitive dysfunctions in a group with persistent problems after whiplash due to injuries to the posture control system and related structures. The whiplash subjects (n = 23) were selected on the basis of their reduced gain in the Smooth Pursuit Neck Torsion test (SPNT). The WL group differed significantly from a closely matched control group on tests of learning and memory, and prolonged divided attention and concentration. After attempting to rule out other ways of interpreting these differences (such as pain, depression, medication, and premorbid health problems), these data were interpreted as lending support to the notion of a causal connection between the disturbed posture control system and some cognitive malfunctions.
以往关于挥鞭样损伤（WL）事故是否真的导致认知变化的研究结果各异。本研究的目的是确定一组因姿势控制系统及相关结构损伤而在挥鞭样损伤后存在持续问题的人群中可能存在的认知功能障碍。挥鞭样损伤受试者（n = 23）是根据其在平稳跟踪颈部扭转试验（SPNT）中增益降低来选取的。在学习与记忆测试、延长的注意力分散和注意力集中测试中，挥鞭样损伤组与紧密匹配的对照组存在显著差异。在试图排除对这些差异的其他解释方式（如疼痛、抑郁、药物治疗和病前健康问题）后，这些数据被解释为支持姿势控制系统紊乱与某些认知功能障碍之间存在因果联系这一观点。
