Hypothetical control of postural sway [PDF]
Journal of The Royal Society Interface, 2020 AbstractQuiet standing exhibits strongly intermittent variability that has inspired at least two interpretations. First, variability can be intermittent through the alternating engagement and disengagement of complementary control processes at distinct scales.

Posture Prediction for Healthy Sitting using a Smart Chair [PDF]
International Conference on Advances of Science and Technology
2021, LNICST 411, pp 401-411, 2022 Poor sitting habits have been identified as a risk factor to musculoskeletal disorders and lower back pain especially on the elderly, disabled people, and office workers. In the current computerized world, even while involved in leisure or work activity, people tend to spend most of their days sitting at computer desks.

Postural control in blind subjects [PDF]
Einstein (São Paulo), 2011 ABSTRACT Objective: To analyze postural control in acquired and congenitally blind adults. Methods: A total of 40 visually impaired adults participated in the research, divided into 2 groups, 20 with acquired blindness and 20 with congenital blindness − 21 males and 19 females, mean age 35.8 ± 10.8.

Lifespan changes in postural control
Scientific Reports, 2023 AbstractLifespan development of postural control shows as an inverted U-shaped function with optimal performance in young adults and similar levels of underperformance in children and older adults. However, similarities in children and older adults might conceal differences in underlying control processes.

Evaluation of Postural Muscle Synergies during a Complex Motor Task in a Virtual Reality Environment [PDF]
, 2022 In this study, we investigate how the central nervous system (CNS) organizes postural control synergies when individuals perform a complex catch-and-throw task in a virtual reality (VR) environment. A Robotic Upright Stand Trainer (RobUST) platform, including surface electromyography and kinematics, was used to investigate how the CNS fine-tunes ...

A Dynamic Computational Model of Head Sway Responses in Human Upright Stance Postural Control during Support Surface Tilt [PDF]
A Dynamic Computational Model of Head Sway Responses in Human
Upright Stance Postural Control During Support Surface Tilt. In ICINCO 2023 -
Volume 1, pages 17-28 ISBN: 978-989-758-670-5; ISSN: 2184-2809, 2023 Human and humanoid posture control models usually rely on single or multiple degrees of freedom inverted pendulum representation of upright stance associated with a feedback controller. In models typically focused on the action between ankles, hips, and knees, the control of head position is often neglected, and the head is considered one with the ...

How cognitive loads modulate the postural control of older women with low back pain?
BMC Geriatrics, 2021 Background The capacity of postural control is a key factor related to falling in older people, particularly in older women with low back pain (LBP). Cognitive involvement in postural control increases with age. However, most scholars have not considered

A Novel Posture Positioning Method for Multi-Joint Manipulators [PDF]
IEEE Sensors Journal, 2020, 2020 Safety and automatic control are extremely important when operating manipulators. For large engineering manipulators, the main challenge is to accurately recognize the posture of all arm segments. In classical sensing methods, the accuracy of an inclinometer is easily affected by the elastic deformation in the manipulator's arms.
