The effect of prophylactic ankle braces on postural sway
… the effects of a prophylactic ankle brace on postural sway, in the ankle of a previously uninjured athlete. Twenty healthy individuals aged between 20 and 27 years, who were currently involved in a sporting activity, participated in this study. Participant's single leg postural sway was …

Development and Validation of Wearable Systems for Human Postural Sway Analysis
… sensor developed (Mini-Logger) was validated for sway acquisition in laboratory setting. Further the novel sensor was tested on healthy adults for its sensitivity with postural sway at 12 different standing conditions. The results from this study could help in development of inexpensive wearable …

Measuring changes in cognitive load in language processing through measuring postural sway
… difficult the content, the more subjects will sway. Although standing itself is a common enough task, the biological requirements of postural control during standing are fairly complex, requiring the involvement of an uninterrupted flow of afferent signals reaching the central nervous system …

The Influence of Feedback on Supra-postural Task Performance and Postural Sway Variability
<p>Postural sway variability is reduced when a person lightly touches a surface with the fingertip, even when the amount of force produced is insufficient to mechanically stabilize the body. Manipulating feedback about a supra-postural task, such as isometric light force, alters task constraints. …

Comparison of shod vs nonshod on balance and postural sway in older adults
… yields better static and dynamic balance, and postural sway values than a group wearing shoes (WS). Twelve older adults (65-92 years) were randomly assigned into a BT or WS group. Both groups participated in 50 minute exercise sessions, three days a week, for six weeks. The sessions included …

Postural Sway, EEG and EMG Analysis of Hip and Ankle Muscles during Eight Balance Training Tasks
The purpose of this study was to examine postural sway, cortical response and muscle activation of the hip and ankle muscles during eight balance tasks routinely used in sensorimotor training. This was a single group repeated measure study. The postural sway; the power of alpha, beta and sigma wave …

Effects of Lumbar Extensor Fatigue on Ankle Joint Motion Sense and Prolonged Effect on Postural Sway
… balance. Lumbar extensor fatigue (LEF) increases postural sway which has been associated with degradations in balance. Study one focuses on the effects of fatiguing time and fatigue level on the duration of these increases in postural sway. Measures of postural sway were collected before fatigue …

Evaluation of Circumferential Ankle Pressure as an Ergonomic Intervention to Maintain Balance Perturbed by Localized Muscular Fatigue of the Ankle Joint
… musculatures has been shown to adversely affect postural control. However, the potential for pressure application to mitigate the effects of localized muscle fatigue on postural control has not yet been determined. This study investigated specifically the effects of circumferential ankle pressure …

Quantifying Structural Changes with the Application of Osteopathic Manual Medicine (OMM) in Tegucigalpa, Honduras
… 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 medicine (OMM) was used to correct structural dysfunction found in the study participants at …

Validation of seated postural control measures in non-ambulatory persons with Multiple Sclerosis
Poor seated postural control negatively impacts the performance of daily activities in non-ambulatory persons with Multiple Sclerosis (PwMS) and may be a potential target of rehabilitation. However, there is a lack of validated clinical measures of seated postural control in persons with MS, thus …

BIOMECHANICAL MARKERS AS INDICATORS OF POSTURAL INSTABILITY PROGRESSION IN PARKINSON'S DISEASE
… quantitative biomechanical parameters of postural instability in patients with Parkinson’s disease (PD) that can in turn be used to assess fall risk. Currently, clinical assessments in PD are not sufficiently sensitive to predict fall risk, making a history of falls to be the best …

The Effects of Concurrently Performing Balance and Cognitive Tasks Across the Life Span
… A motion analysis system was used to measure postural sway. Reaction time and accuracy in the cognitive tasks were collected. The relative changes of performance from the single- to dual-task, dual-task costs, were also calculated. Results showed that children maintained balance performance at …

The biomechanical consequences of body size differences in humans
… spring angle during running; 3) quiet standing postural sway and stance characteristics; and 4) variability and scaling patterns in bone microstructure of the femur. Additionally, this dissertation explored different statistical approaches for examining each of these areas to determine whether …

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 …

Toward understanding factors affecting falls among individuals who are obese
… the relationship between plantar sensitivity and postural sway during quiet standing. Plantar sensitivity was measured as the force threshold at which an increasing force applied to the plantar surface of the foot was first perceived, and the force threshold at which a decreasing force was last …

Proprioceptive acuity in patients with a torn anterior cruciate ligament following a rehabilitation programme
… of limb position, single leg static balance (postural sway)using a stable force platform, and dynamic balance using the Star Excursion Balance(SEBT) test were used as measures of proprioceptive acuity.Results: Results show that there are significant differences in proprioception betweeninjured …

The effect of injury on ankle range of motion and proprioception
To assess the effect of injury to the ankle on postural sway in participants with a history of no injuries, one injury and two or more injuries. To compare the changes in passive range of motion of the ankle in participants with no injuries, one injury and two or more injuries. The results suggest …

An investigation into the ergonomics of standing
… at how humans maintain upright posture through postural control and the role of the 'anti-gravity muscles'. Postural sway is inherent to standing and this is examined in some detail along with the concepts of centre of foot pressure and effective foot base. Attention is drawn to the fact that …
