The Effects Of Age And Distraction On Interlimb Synchronization Of The Center Of Pressure
… distractibility. This study examines the effects of cognitive distractions on interlimb synchronization and balance in young and older adults. Participants performed quiet standing trials on separate force plates under eyes-open and eyes-closed conditions, with and without cognitive distraction …

Generalizability of Center of Pressure Measurements Across Age Populations
The reliability of common Center of Pressure (COP) measurements was systematically investigated. Studies on the control of posture during quiet standing using force platform data lack standardization in measurement protocols (especially trial length and number). Guidelines for methodology that met …

Classification of Human Postural and Gestural Movements Using Center of Pressure Parameters Derived From Force Platforms
… from ground reaction forces and the body's center of pressure (COP). The purpose of this research is to classify human body movements, even the subtle movements, using a carefully selected feature set. For the first time, we propose a method to classify postural and gestural movements using …

Changes in Balance with Brain Inflammation: Sensitivity in Dual Motor Mechanisms
… due to potential long-term consequences of traumatic brain injuries. Evaluating balance alterations is crucial for understanding post-injury motor control strategies. This study introduces a novel approach to understanding center of pressure (COP) dynamics during quiet stance tasks for …

Understanding the Independent Effects of Inertia and Weight on Balance
… deficiencies in certain populations. The goal of this study was, therefore, to investigate the effects of altered dynamics, namely increased inertia and increased weight, on standing balance. Sixteen normal-weight male participants completed quiet standing in a custom-built backboard under four …

Quantifying Structural Changes with the Application of Osteopathic Manual Medicine (OMM) in Tegucigalpa, Honduras
The primary purpose of this research was to compare quantifiable structural asymmetry to changes visualized in center of pressure (CoP) and/or postural sway by the use of an Isobalance forceplate in order to introduce principles of osteopathic medicine to a Latin America culture. Osteopathic manual …

Effects of Obesity on Balance Recovery in Response to Small Postural Perturbations
… health concern associated with an increased risk of falls. The majority of falls are thought to result from some kind of postural perturbation, yet the biomechanical mechanisms as to why obese individuals fall more often is unclear. Therefore, the goal of this study was to investigate the effects …

Biomechanical Evaluation of Lumbar Extensor Fatigue Effects on the Postural Control System
Falls from heights are the fourth leading cause of occupational injury and fatality in the United States. In particular, construction workers such as roofers are often exposed to high risk environments. Recent research has reported that a leading cause of falls among workers is a loss of balance. …

Towards a quantitative assessment of early-stage Parkinson’s disease using BioVRSea paradigm
… diseases (NDDs) are considered one of the twenty-first century most pressing public health issues. One consistent risk factor for developing NDD is increasing age and the increased longevity of the world population results in the rise of NDDs. Parkinson's disease (PD) is the second …

Exploring the Use of Supervised Machine Learning Algorithms to Classify Simulated Balance Deficits
The purpose of this study was to determine the achievable accuracies of supervised machine learning algorithms for classifying simulated balance deficits and the number of participants needed to maximize those accuracies. The long-term goal is to create a classification system that can accurately …

Evaluation of Linear and Nonlinear Postural Stability Measurements Following Concussion
… annually in the United States. 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) …

Head Position Variability During Single and Dual-task Tandem Gait Concussion Testing Protocol
… and time to complete between two head positions of cervical neutral and cervical flexion during single and dual-task tandem gait. METHODS: 25 apparently healthy subjects (age=21.9±1.41 years) performed tandem gait walking along a 3-meter piece of tape affixed to an instrumented walkway (30 Hz, …

ALTERATIONS IN POSTURAL CONTROL FOLLOWING AN ACUTE BOUT OF SOCCER HEADING
This study sought to determine if an acute bout of soccer heading adversely altered postural control and pronounced self-reported symptoms of cerebral concussion. Sixteen collegiate soccer players were randomly assigned to one of two groups: control (CG) or experimental (EG). Participants either …

Understanding Mediolateral Stability During Gait in Persons with Early-Stage Multiple Sclerosis
… stability is affected in those with low levels of disability due to MS. The objective of this multiple case series was to explore how M-L stability during gait is affected in persons with early-stage MS using narrow-base walking. Narrow-base walking has not previously been used in the MS …

Differences in Balance and Muscle Activation Strategies during Gait Initiation at Different Speeds between Young and Middle-Aged Adults
<p>Middle-age adults’ (MA) self-report of falls are greater compared to younger adults (YA) during ambulation. A previous study found that MA compared to YA use different strategies taking one-step forward at a fast speed. No other studies have compared the effect of two different speeds on balance …

The Influence of Casual Footwear on Human Balance
<p>Falls are the third leading cause of unintentional death in homes and communities in the United States, causing 27,800 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 …

Electromyographical Analysis of and Medial-Lateral Anticipatory Postural Adjustments prior to Stepping and Single Leg Reaching in Chronic Unstable Ankles
<p>The repetitive occurrence of multiple lateral ankle sprains within the physically active population is termed chronic ankle instability (CAI). Previous research remains limited regarding the preparatory activation of the dynamic restraints at the hip (gluteus medius-GM, adductor magnus-AM), and …

Development and evaluation of postural control models for lifting motions and balance control
… simulating human motions is a major function of and challenge to digital human models 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, …

Use of Statistical Mechanics Methods to Assess the Effects of Localized muscle fatigue on Stability during Upright Stance
… 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 numerous methods have been developed in order to quantify such …

Visual-Oculomotor and Head Movement Strategies in Postural Control
Postural control requires the integration of visual, vestibular, and proprioceptive information to maintain stability. The gold standard for inferring postural control relies on lab-based tools, such as force plates and full-body motion capture to track center of mass (COM) and center of pressure …
