Abstract
People with Parkinson's disease (pwPD) have reduced adaptability to postural control during prolonged standing compared to neurologically healthy individuals (control). Objective. The study aimed to characterize postural changes during prolonged standing and their effect on postural control in pwPD compared to control. We recorded the body sway of the second lumbar vertebra of 23 pwPD and 23 control while they performed prolonged standing (15 min). The number and amplitude of the body sway patterns (shifts, fidgets, and drifts), the root mean square, velocity, and frequency of the body sway were analyzed. The number of shifts in the anterior-posterior (AP) and medial-lateral (ML) directions was greater for the pwPD than the control. In addition, the amplitudes of shifts in the AP direction and fidgets in the AP and ML directions were greater for the pwPD than the control. Our results show that: (1) A larger number of shifts of body sway suggest references positions are frequently changing; (2) Fidgets is a pumping mechanism and can be sensory-demand action to restore mechanoreceptors activity on the foot sole; and (3) No drift changes may suggest there is no slow migration of reference position. We conclude that pwPD exhibits different behavior than healthy ones during prolonged standing, suggesting that prolonged standing could distinguish individuals with Parkinson's disease.
与神经系统健康的个体（对照组）相比，帕金森病患者（pwPD）在长时间站立时对姿势控制的适应性降低。研究目的本研究旨在描述帕金森病患者与对照组相比在长时间站立时的姿势变化及其对姿势控制的影响。我们记录了 23 名腰椎间盘突出症患者和 23 名对照组患者在进行长时间站立（15 分钟）时第二腰椎的身体摇摆。我们分析了身体摇摆模式（移动、躁动和漂移）的数量和幅度、身体摇摆的均方根、速度和频率。与对照组相比，肢体摇摆症患者在前-后（AP）和内-外（ML）方向的摇摆次数更多。此外，与对照组相比，肢体摇摆症患者在 AP 方向上的摇摆幅度以及在 AP 和 ML 方向上的躁动幅度更大。我们的结果表明(1)身体摇摆移动的次数越多，表明参考位置变化越频繁；(2)躁动是一种泵机制，可以通过感觉驱动作用来恢复足底机械感受器的活动；(3)无漂移变化可能表明参考位置没有缓慢迁移。我们的结论是，帕金森病患者在长时间站立时表现出与健康人不同的行为，这表明长时间站立可以区分帕金森病患者。
期刊介绍：
Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome.
These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
