Showing papers in "Gait & Posture in 2005"

TL;DR: For STA to be compensated for effectively, it is here suggested that either its subject-specific pattern is assessed by ad hoc exercises or it is characterized from a large series of measurements on different subject populations.

TL;DR: An effort to systematize the different theoretical and experimental approaches to the problems involved and related nomenclatures is needed to facilitate data and knowledge sharing, and to provide renewed momentum for the advancement of human movement analysis.

TL;DR: It is concluded that consistent gait differences exist between hemiparetic and non-disabled subjects walking at matched speeds, and the differences provide insights, concerning hemiperetic impairment and related compensatory strategies, that are in addition to the observation of slow walking speed.

TL;DR: It was concluded that mean displacement velocity seems to be the most informative parameter in most situations, and sum of maximal deviation time (SDT) was proposed showing complete discrimination between frail elderly and other old subjects when obtained while visual input was suppressed.

TL;DR: The goal of the present paper is to review the different approaches dealing with joint kinematics sensitivity to rotation axes and the precision of anatomical landmark determination, limited to studies performed with video-based stereophotogrammetric systems.

TL;DR: The data indicate that the GAITRite system is a valid tool for measuring both averaged and individual step parameters of gait, also valid for use in older subjects following knee joint replacement surgery.

TL;DR: Although skin-marker derived kinematics could provide repeatable results this was not representative of the motion of the underlying bones and a standard error of measurement is proposed for the reporting of 3D knee joint kinematic.

TL;DR: The finding that brain lesions involving particularly the parieto-temporal junction are associated with poor postural control, suggests that normal sensory integration is critical for balance recovery.

TL;DR: Evolutionary aspects of the human spine and pelvis are reviewed, including their impact on several clinically relevant aspects of human gait and posture and the selective agencies that have guided its evolution during the past three million years.

TL;DR: The hypothesis that temporal gait variability is increased among older adults with a cautious gait and a higher-level gait disorder (HLGD) is tested, suggesting that the gait changes in older adults who walk with fear may be an appropriate response to unsteadiness, are likely a marker of underlying pathology, and are not simply a physiological or psychological consequence of normal aging.

TL;DR: The contribution of the support limb to prevent a fall after tripping is decreased in older adults, and lower limb strength could be an underlying factor and strength training might help to reduce fall risk.

TL;DR: It is argued that this figure identifies the lower bound of the range of values which characterise normal sway in quiet standing, whereas the upper bound is given by the estimates performed with much smaller test disturbances which yield a higher value: 91+/-23%.

TL;DR: Step width variability demonstrated low association with the trunk variability measures, and did not differ between groups, which are compatible with a notion that mediolateral interstride trunk variability represents a different aspect of motor control than variability in the direction of propulsion.

TL;DR: An understanding of the motor control mechanisms underlying impact absorption is essential to understand common anticipatory and reflex mechanisms involved in a broader variety of movements such as running and jumping.

TL;DR: The present investigation is the first to provide normative data of GRF parameters on gait variability and symmetry of two consecutive steps during level gait and stair ambulation, and it is the intention that the results may be used as a basis for comparison with patient data.

TL;DR: Evidence suggests that paretic muscle strength and the ability to load the paretIC limb are important factors underlying the able to rise from a chair in individuals with chronic stroke.

TL;DR: The findings of this study suggest that effective prevention and rehabilitation of inversion sprains should include attention to gait patterns and adjustments of foot biomechanics.

TL;DR: Although not all applications of Fr to locomotion have been covered, the review offers an important historical context for all researchers of bipedal gait, and extends the idea of dimensionless scaling of gait parameters.

TL;DR: It is indicated that trunk sway measures recorded during stance and gait tasks provide useful information on balance deficits leading to falls in PD patients, and a simple test battery of stance andGait tasks that could discriminate between PD patients who had recent falls and controls is defined.

TL;DR: The human fossil record is one of the most complete for any mammal and provides insights into the origin and design of the modern human frame, including the unusual corticotrabecular structure of the human proximal femur, and the authors' markedly elongated lower limb.

TL;DR: The results indicate that gait speed highly correlated with stability against backward balance loss at slip onset and touchdown of compensatory stepping, indicating the motor program for gait regulation may play a role in modulating the compensatory step.

TL;DR: It is concluded that the proper selection of training parameters can improve the gait pattern practiced by individuals with hemiparesis during treadmill training and may improve treatment outcome.

TL;DR: The repeatability of both 3D kinematic measurements of arm movement during simple upper limb tasks and lower limb movement during gait analysis was evaluated in 10 children with hemiplegic cerebral palsy, suggesting it may be able to be used as an outcome measure in the hemipLegic upper limb.

TL;DR: Temporal plantar pressure variables were found to be reliable and both gender and asymmetry influences could be neglected and provide a reliable and representative reference dataset for temporal characteristics of foot roll-over during jogging of young adults.

TL;DR: Treadmill walking in older adults after a single 15-min training session could not be generalised to overground walking.

TL;DR: It is proposed that high-risk older adults may prioritize the planning of future actions over the accurate execution of ongoing movements and that adoption of this strategy may contribute to an increased likelihood of falls.

TL;DR: The irregular surface had a greater effect on the gait variability of healthy OW than on that of healthy YW, along with the effects of advancing age and low light conditions, as well as comfortable gait speed.

TL;DR: Results provide support for the hypothesis that children lack the neuromuscular maturity, especially at the ankle, to produce an adult-like gait pattern.

TL;DR: It was showed that there is regional differentiation in TrA activity with challenges to postural control and that body position influences the postural responses of the abdominal muscles.

TL;DR: The results suggest that the variability of minimum foot clearance, and lack of precautionary increases in foot clearance under reduced lighting may contribute to falls on stairs by the elderly.
