The effect of prophylactic ankle braces on postural sway
… 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 evaluated on …

Leaves that Sway: Gold Xianbei Cap Ornaments from Northeast China
… in the Chinese histories as buyao (“step-sway”) ornaments because their thin sheet gold leaves tremble and sway with each step the wearer takes. However, leaf-covered gold crowns and headdresses excavated from tombs across Central Asia, Western Asia, and the Mediterranean have also been …

Effect of Tactile Feedback on Reducing Body Sway in Elderly
<p>Context: Body sway increases in the elderly due to normal aging and a high incidence of disease such as diabetes. Increased body sway is associated with an elevated risk of falling. Falling is one of the major causes of morbidity and mortality in the elderly. Objectives: The purpose of this …

Body Sway and Aim Point Fluctuation in Rifle and Pistol Shooters
… of force plate data used to measure body sway and the relationship between this body sway, aim point fluctuation and performance in shooting. Quantisation error in and resolution of selected body sway parameters were calculated from force plate data sampled using 12-bit and 16-bit analog …

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
… 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 strength, …

Adaptation of Delayed Position Feedback to the Reduction of Sway of Container Cranes
… 15 m at the end of motion, while reducing the sway to 50 mm within 5.0 s at the end of the transfer maneuver. The performance of the controller has been demonstrated theoretically using numerical simulation. Moreover, the performance of the controller has been demonstrated experimentally using …

Anti-sway control of a construction crane modeled as a two-dimensional pendulum
… of the operator. The problem of controlling sway of the load due to crane motion, or wind effects must be solved dynamically by the operator to increase productivity and maintain safety. At the hands of inexperienced operators safety is sometimes sacrificed in order to expedite the required …

An Investigation of Fraxinus Americana Branch Sway Using a 3 Dimensional Motion Capture System
… studies. Even fewer studies have examined tree sway response to natural wind loaded conditions. In this investigation, branch frequencies were calculated for three <em>Fraxinus americana </em>using a three-dimensional motion capture system for both wind loading and hand loading conditions. …

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
… 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 and at 3 …

Individual & Combined Effects of Hyperthermia, Dehydration & Fatigue Balance
… variables were: center of pressure (COP), mean sway velocity, mean COP sway path, and average elliptical sway area for both the static and dynamic tests, as well as BESS individual stance scores and BESS total score. Separate repeated measures analyses of variance were performed to evaluate the …

Avaliação do Microsoft Kinect v2 como instrumento de medição das oscilações posturais
The measurement of body sway is employed in the assessment of postural control. However, many devices assigned to this function are bulky or require special preparation, such as attachment of markers. In this study, The Microsoft Kinect v2, which is a portable and markerless motion sensor, was used …

Evaluation of Circumferential Ankle Pressure as an Ergonomic Intervention to Maintain Balance Perturbed by Localized Muscular Fatigue of the Ankle Joint
… (low or high PA) used as a covariate. Postural sway during quiet standing was assessed using a force platform both pre- and post-fatigue as well as in the absence and presence of CAP. Application of CAP resulted in larger postural sway in individuals with low PA, and reduced postural sway in …

The Efficacy of Using Color In Sub-Threshold Vibration to Improve Older Adult Balance
… change in state. We hypothesized that (1) the sway measures before stimulation will differ across subjects and vary within a subject across the sessions. (2). Each vibration color would cause a change in the state different from the placebo. (3)The efficacy of utilizing subthreshold vibration …
