Online detection and control of car body low-frequency swaying in railway vehicles
Vehicle System Dynamics, 2021 Low-frequency swaying is an abnormal vibration of railway vehicles. It is manifested by a low-frequency and high-amplitude swaying of the car body, which continues for a period of time, posing a significant threat to the passengers’ ride comfort and even

Swaying to the complex motion of a visual target affects postural sway variability
Gait & Posture, 2020 Voluntary shifting body weight in the anteroposterior direction is an important element of daily life activities, such as rising from a chair or initiating a step. In order to accommodate the daily-life challenges of such tasks, voluntary postural sway needs to be flexible and variable.In this study we asked how whole-body tracking of a complex visual ...

Using inertial measurement units to identify medio-lateral ground reaction forces due to walking and swaying [PDF]
Journal of Sound and Vibration, 2018 Horizontal ground reaction forces (GRFs) due to human walking and swaying have been investigated (respectively) through direct measurements using a treadmill and a set of force plates.

Nonstationarities of postural sway
IEEE Engineering in Medicine and Biology Magazine, 2003Time-frequency analysis of visually induced postural sway has uncovered potentially important time-dependent spectral changes in sway, particularly over intervals shorter than most trial lengths (tens of seconds). Specifically, our studies of center of pressure (COP) in response to sinusoidal (0.25 Hz) moving scene perturbations demonstrate that there ...

Relationship between Head Sway and Center of Foot Pressure Sway
Auris Nasus Larynx, 1995We investigated the correlation between body sway and head sway in 64 healthy subjects who stood on a force-measuring platform. Each subject wore a helmet attached to a cephalograph and was asked to stand as still as possible on a platform with his feet close together for 60 sec.

Systems and Computers in Japan, 1998
When we simulate a natural object by computer graphics, motion simulation is important as well as shape modeling. Various attempts have been made to produce CG images. However, most of them studied growth models of tree shapes or texture-generating methods, and simulation methods of tree swaying have seldom been studied.

SWAY AS PREDICTOR OF INJURIES IN CHILDREN
British Journal of Sports Medicine, 2014IntroductionPoor postural control measured as sway performance is an intrinsic risk of injury and re-injury among adults. This has not been investigated in children.ObjectiveTo investigate the associations between balance, measured as sway performance, and the risk of both acute and overuse injuries in a population of children.

Effect of Sway Frequency on the Joint Angle and Center of Pressure in Voluntary Sway
Journal of Motor Behavior, 2023Voluntary sway is the periodic movement of one's body back and forth. The study aimed to clarify the effects of sway frequency on center of pressure and joint angle during voluntary sway. We measured 10 unrestricted voluntary sway conditions with different frequencies and natural pace conditions.
