Perceptual adaptation during a balancing task in the seated posture and its theoretical model
Biological Cybernetics, 2021This paper proposes a theoretical model of the control and perception mechanism in human balance. Human balance perception is evaluated by the subjective upright posture, the posture at which a person does not feel he/she is at an incline. Our balance experiments in the seated posture showed that the subjective upright posture changed after the ...

Multi-objective optimisation approach for predicting seated posture considering balance
International Journal of Vehicle Design, 2009Common tasks of vehicle operation are performed while seated. Using a whole-body human articulated model, we propose a methodology of predicting realistic seated postures that is based on optimising multiple-objective functions. The idea of zero-moment point (ZMP), inspired from the stability of bipedal motion, is applied to the seated postures as the ...

Effectiveness of Balance Seat on Vibration Comfort
2018People who spend a significant amount of time on driving are concerned about seating comfort. Seat cushion is considered as one of the important factors affecting the comfort of your seat. In automotive seat cushions, flexible polyurethane foam has been widely used for vibration isolation and cushioning purpose.

The effects of trunk stiffness on postural control during unstable seated balance
Experimental Brain Research, 2006This paper focused on the relationship between trunk stiffness and postural control during unstable seated balancing. We hypothesized that an increase in trunk stiffness would degrade postural control, and further hypothesized that signal dependent noise (SDN), resulting in increased muscle force variability, was responsible for this impairment.

Seated balance during pitch motion with and without visual input
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013The study of seated balance and postural control, specifically in relation to wheelchair propulsion, has been an area of interest for quite some time. In biomedical and rehabilitation research this has led to the potential of treatment and prevention of spinal cord and musculoskeletal injuries.

Predicting the Response of a Seat-Occupant Model by Using Incremental Harmonic Balance
SAE Technical Paper Series, 2013<div class="section abstract"><div class="htmlview paragraph">Vehicle occupants are exposed to low frequency vibrations which can adversely affect the ride comfort. Exposure to vibrations can also lead to problems ranging from fatigue and lower back pain to more serious issues like injuries to the spine.

Stability threshold during seated balancing is sensitive to low back pain and safe to assess
Journal of Biomechanics, 2021Challenging trunk neuromuscular control maximally using a seated balancing task is useful for unmasking impairments that may go unnoticed with traditional postural sway measures and appears to be safe to assess in healthy individuals. This study investigates whether the stability threshold, reflecting the upper limits in trunk neuromuscular control, is

Effect of Data Selection on the Loss of Balance in the Seated Position
2009A fast and accurate detection of the loss of balance (LOB) can reduce the elderly fall that is one of the most dangerous injuries. Real-time detection of body reactions against a fall will be used to improve the performance of devices for the elderly. The loss of balance is detected by control error anomaly (CEA) that is an unusually large value of the
