Abstract

Background: Increased sway within a stationary base of support (BoS) is often interpreted as worse postural control. However, larger persons may have larger feet, facilitating broader sway patterns within their wider/longer base. Time to boundary (TtB) incorporates foot placement dimensions into the calculation and, thus, may not be confounded by dissimilar anthropometric features.

Methods: Ninety-seven healthy adults stood quietly on a force platform for 150 s with their feet together while barefoot. BoS characteristics, center of pressure motion, and TtB were calculated and correlated with body height for eyes open and closed conditions.

Results: BoS width, length, and total area positively correlated with body height. Path length and sway area were positively correlated with height for both vision conditions, with stronger correlations observed with eyes closed. At the same time, TtB was not correlated with height in either visual condition. Consequently, the tallest 20 individuals in the sample displayed greater path length and sway areas but equal TtB as the shortest 20 persons.

Conclusion: Observed differences in position-based center of pressure measures could be an artifact of body size inequality not postural (in)stability. Meanwhile, TtB is normalized to BoS and is, therefore, not confounded by anthropometric differences.

平衡的荒诞故事：高度对姿势控制措施的影响。

背景：在固定的支撑基础（BoS）内增加的摇摆通常被解释为更差的姿势控制。然而，体型较大的人可能有更大的脚，在他们更宽/更长的基础上促进更广泛的摆动模式。边界时间（TtB）将脚放置尺寸纳入计算，因此可能不会被不同的人体测量特征混淆。方法：97名健康成人，赤脚，双脚并拢，静立在用力台上150 s。计算睁眼和闭眼条件下的BoS特征、压心运动和TtB与身高的相关性。结果：BoS宽度、长度、总面积与体高呈正相关。在两种视觉条件下，路径长度和摇摆面积与高度呈正相关，闭上眼睛的相关性更强。同时，在两种视觉条件下，TtB均与身高无关。因此，样本中最高的20个人显示出更大的路径长度和摆动面积，但与最矮的20个人相同。结论：体位压力中心测量的差异可能是体型不平等的产物，而不是体位稳定性的产物。同时，TtB归一化为BoS，因此不受人体测量差异的影响。

期刊介绍： Motor Control (MC), a peer-reviewed journal, provides a multidisciplinary examination of human movement across the lifespan. To keep you abreast of current developments in the field of motor control, it offers timely coverage of important topics, including issues related to motor disorders. This international journal publishes many types of research papers, from clinical experimental to modeling and theoretical studies. These papers come from such varied disciplines as biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. Motor Control, the official journal of the International Society of Motor Control, is designed to provide a multidisciplinary forum for the exchange of scientific information on the control of human movement across the lifespan, including issues related to motor disorders. Motor Control encourages submission of papers from a variety of disciplines including, but not limited to, biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. This peer-reviewed journal publishes a wide variety of types of research papers including clinical experimental, modeling, and theoretical studies. To be considered for publication, papers should clearly demonstrate a contribution to the understanding of control of movement. In addition to publishing research papers, Motor Control publishes review articles, quick communications, commentaries, target articles, and book reviews. When warranted, an entire issue may be devoted to a specific topic within the area of motor control.
