Quantification of the human postural control system to perturbations
… standing posture is inherently unstable. The postural control system (PCS), which maintains standing posture, is composed of the sensory, musculoskeletal, and central nervous systems. Together these systems integrate sensory afferents and generate appropriate motor efferents to adjust posture. …

Biomechanical Evaluation of Lumbar Extensor Fatigue Effects on the Postural Control System
… of balance and factors that influence postural control is necessary. The effect of neuromuscular fatigue has been addressed by many investigators; however, few studies have examined the effect of localized fatigue in muscles not located in the lower extremities. Because low back fatigue …

Development and evaluation of postural control models for lifting motions and balance control
… and integrating humans in computer-aided design systems. Numerous successful applications of human motion simulation have already demonstrated their ability to improve occupational efficiency, effectiveness, and safety. In this dissertation, a novel motion simulation model using fuzzy logic …

Postural control and adaptation to threats to balance stability
Postural control is the ability to maintain equilibrium and orientation in a gravitational environment. It is dependent on feedback and feedforward mechanisms that generate appropriate corrective movement based on body-sway motion detected primarily by visual, vestibular, and proprioceptive sensory …

Evaluation of Linear and Nonlinear Postural Stability Measurements Following Concussion
… A large number of these athletes suffer from postural instability following concussion. Postural control assessment has become a recommended tool to determine readiness to return to play. Measurement of postural control through the use of center of pressure (CoP) variables may provide a …

The effects of changing head position and posture on head tremor in individuals with essential tremor involving the head
… the effects of head position and of different postural control demands on head tremor measures in participants with essential tremor. Methods: Seventeen participants with essential tremor (ET) of the head and 17 control participants took part. Individuals held their heads in varying degrees of …

The Influence of Casual Footwear on Human Balance
… fatalities in 2012. The ability to maintain postural control is an essential part of activities of daily living (ADLs). However, recent types of casual footwear may be putting the body’s postural control system at a functional disadvantage, predisposing wearers to the risk of a fall. The …

Use of Statistical Mechanics Methods to Assess the Effects of Localized muscle fatigue on Stability during Upright Stance
Human postural control is a complex process, but that is critical to understand in order to reduce the prevalence of occupational falls. Localized muscle fatigue (LMF), altered sensory input, and inter-individual differences (e.g. age and gender) have been shown to influence postural control, and …

Postural control in persons with multiple sclerosis: an investigation of dual task cost and physical modeling
Postural control is an essential activity of everyday life. There is ongoing debate concerning the contribution of central and peripheral control processes to the control of upright stance. Multiple sclerosis is known to negatively influence both central and peripheral control processes. This work …

Proprioception and performance in surfing
… may induce changes in the subcomponents of the postural control system including proprioception. Currently, proprioception is not well understood nor examined in surfers, making it difficult to quantify proprioceptive ability and interpret how proprioception may relate to surfing performance. …

Assessing the Effects of Exoskeleton Use on Balance and Postural Stability
… to reduce physical demands, and thereby help control/prevent the risk of overexertion injuries associated with manual material handling. However, it is important to understand whether BSEs also introduce any unintended safety challenges. One potential risk associated with BSE use is increased …

Gait and Postural Analysis in Healthy Young Adults and People with Parkinson's Disease
<p>Postural analysis is the study of how the position of the body in any mode interacts with internal and external forces. This type of analysis is typically used to assess potential abnormalities in the balance control system and to understand how the balance control system changes with time. …

Sensory re-weighting for balance control and the effects of ankle foot orthoses and stance width: A comparison of people with diabetic peripheral neuropathy and healthy participants
… from somatosensory, vestibular and visual systems. Alterations in distal sensory input may result in a re-weighting of the effectiveness of remaining sensations in mediating a stabilising postural response; termed sensory re-weighting. Alterations in posture such as adopting a wider stance …
