Showing papers in "Gait & Posture in 2010"

TL;DR: It is suggested that the WBB could provide the average clinician with a standing balance assessment tool suitable for the clinical setting, given that it is portable, widely available and a fraction of the cost of a FP.

TL;DR: This analysis supports the recommendations of the symmetry ratio as the equation for standardization and step length, swing time and stance time as the gait parameters to be used in the equation.

TL;DR: The studies reviewed show that bipedal static COP measures may be used as a reliable tool for investigating general postural stability and balance performance under specific conditions and recommendations for maximizing the reliability of COP data are provided.

TL;DR: The range of soft tissue artifact reached greater than 25 mm in some cases when comparing the results of reviewed studies, and the quality of previous studies was evaluated using a customised critical appraisal tool.

TL;DR: The findings suggest that the new algorithm using the TAU/TAF cut-off value can accurately classify household and locomotive activities.

TL;DR: This study presents the first evidence that bouts of sedentary activity are power law distributed, and suggests that the power law exponent alpha and the GINI index G, used to describe the pattern of accumulation of Sedentary time, could be used to evaluate and quantify sedentary behaviour.

TL;DR: The results supported the hypotheses that faster gait as well as shorter steps each ameliorates fall risk when a slip is encountered and also revealed that slow gait in itself leads to instability and falls, which is offset by the related decrease in step length.

TL;DR: Ageing does not appear to alter measures of central tendency or shape of the MFC distribution, however greater MFC variability was observed in older compared to younger adults and older fallers compared to older non-fallers in the majority of studies.

TL;DR: These findings are encouraging because they support the potential for recovery of force and power of the lower extremity for individuals with chronic hemiparesis and elucidate underlying mechanisms that contributed to the observed functional improvement in gait speed and distance.

TL;DR: The gait mechanics of THA patients did not return to normal 10.6 months, on average (+/-2.6 mo), following surgery, and further investigation is needed to confirm the reasons whyTHA patients' gait Mechanics do not returnto normal following surgery to develop better surgical techniques and/or rehabilitation programs.

TL;DR: A novel algorithm for the real-time detection and timing of initial (IC) and final contact (FC) gait events is reported, based on a set of heuristic rules extracted from aSet of 1719 steps.

TL;DR: The purpose of this study was to examine test-retest reliability of three gait parameters representing pace, rhythm and variability in healthy older persons during normal and dual task walking and to determine the number of strides necessary to measure the parameters reliably.

TL;DR: Higher C(w) and coactivation in older adults, along with the positive relationship between C(W) andCoactivation implies coactivation contributes to, higher C( w) of older adults.

TL;DR: Findings support the notion that flat-arched feet have altered motion associated with greater pronation during gait; factors that may increase the risk of overuse injury.

TL;DR: The results indicated that mediolateral and anteroposterior COP velocity was greater in individuals with CAI relative to both copers and controls and the peak COP-COM moment arm in the anterobosterior direction were increased, indicating that they successfully discriminated between establishedCopers and individuals withCAI.

TL;DR: In this paper, the authors performed a quantitative analysis of arm swing magnitude and asymmetry that might be useful in the assessment of early Parkinson's disease (PD) using an optically-based motion capture system.

TL;DR: The results demonstrate that the learning benefits of an external attentional focus are generalizable to older learners.

TL;DR: Different age and gender groups had similar gait performance on most of the joint motions, HR, as well as the perceived exertions while walking at a range of PPWS, and performance generally increased with the increasing walking speed.

TL;DR: The differences between those with and without a visual impairment, and between the full vision and no vision conditions, may reflect a more cautious walking strategy and adaptive changes employed to use the foot to probe the ground for haptic exploration.

TL;DR: The results suggested that subjects controlled their movements according to a two-dimensional ARMA process that specifically sought to minimize stride-to-stride variations in walking speed (SS), which fully agrees with experimental findings and also with the basic definitions of statistical persistence and anti-persistence.

TL;DR: The results help to clarify some discrepancies in the literature, suggesting an impaired or immature control of posture, even under the most basic conditions when no afferent or sensory information have been removed or modified, and provide new insight into dynamic balance in children with ASD.

TL;DR: The findings suggest that bilateral balance deficits are not present in patients with chronic ankle instability and the uninvolved limb should not be used as a reference for "normal balance" following an acute lateral ankle sprain.

TL;DR: The aim of the present study was to determine whether force plate variables in single- and dual-task situations are able to predict the risk of multiple falls in a community-dwelling elderly population.

TL;DR: Findings suggest that changes in step-width, step-time, and step-length with dual tasking may be related to future risk of falling.

TL;DR: The gait variable emphasised during dual task training appears to be an important factor in enabling the transfer of training improvements across tasks and can lead to larger steps when walking under dual task conditions in people with PD.

TL;DR: This study estimated clinically meaningful change in measures of gait variability using both distribution- and anchor-based approaches and may identify important changes over time in both clinical settings and research studies.

TL;DR: Investigation of the differences in preferred walking speed determined both on overground and on a treadmill and, to measure walking energy expenditure and spatio-temporal parameters of gait, found O-PWS should be used for oxygen consumption measurement during treadmill walking tests.

TL;DR: It is found that SW was significantly larger, and SWV significantly smaller, during treadmill walking, and that these changes were meaningfully correlated between tasks, suggesting that the goal of the central nervous system may be to maintain a constant MOS(min) regardless of task.

TL;DR: It was shown that standing in the unstable MBT shoe effectively activates selected extrinsic foot muscles and could have implications for strengthening and conditioning these muscles.

TL;DR: The results of this study indicate subtle changes in postural control during standing in people with mild-to-moderate impairments due to MS under normal and restricted vision and different levels of self-reported fatigue.
