Idiopathic scoliosis and balance organisation in seated position on a seesaw [PDF]

open access: yesEuropean Spine Journal, 2010
The aim was to determine the biomechanical processes involved in postural regulation when self-imposed disturbances occur in the seated position in the antero-posterior direction. Twelve female adolescents with right thoracic scoliosis (SG) (Cobb = 30.4 degrees +/- 9.7) and 15 control adolescents (CG) were included in this study.

Postural seated balance in children can be assessed with good reliability

Gait and Posture, 2016
Seated postural stability can be measured using Tekscan, CONFORMat. Standing postural stability has gained great clinical and, research value by use of different force platforms with mostly good reliability. No reliability testing or biologic variation assessment has been documented regarding seated balance. This study determines the reliability of the

Effects of seated whole-body vibration on postural control of the trunk during unstable seated balance

Clinical Biomechanics, 2008
Low back disorders and their prevention is of great importance for companies and their employees. Whole-body vibration is thought to be a risk factor for low back disorders, but the neuromuscular, biomechanical, and/or physiological mechanisms responsible for this increased risk are unclear.

Effects of reflex delays on postural control during unstable seated balance [PDF]

open access: yesJournal of Biomechanics, 2009
Patients with low-back pain (LBP) exhibit longer trunk muscle reflex latencies and poorer postural control than healthy individuals. We hypothesized that balance during a simulated postural control task would become impaired when the delays exhibited by LBP patients were incorporated into neuromuscular control.

Networked equilibrium sharing system "balance seat"

Proceedings of the 2005 ACM SIGCHI International Conference on Advances in computer entertainment technology, 2005
This paper presents a networked system connecting real space, which is shared and operated by three people.We made three pneumatic triple-axis motion platforms as a system to share a "sense of balance" with other people, and examined control methods for this system.

Effect of age on detecting a loss of balance in a seated whole-body balancing task

Clinical Biomechanics, 2005
Most falls are attributed to a loss of balance without a quantitative definition of the term. It has been proposed that a loss of balance is detectable as an unusually large (anomalous) value of the system control error. The hypotheses were tested that age will not affect the detection of control error anomaly, or prediction of the associated ...

A Vibrotactile Feedback Device for Seated Balance Assessment and Training

Journal of Visualized Experiments, 2019
Postural perturbations, motion tracking, and sensory feedback are modern techniques used to challenge, assess, and train upright sitting, respectively. The goal of the developed protocol is to construct and operate a sitting platform that can be passively destabilized while an inertial measurement unit quantifies its motion and vibrating elements ...
