Showing papers in "Gait & Posture in 2006"

TL;DR: It was found that variations on the model produced only minimal changes in repeatability, the only significant change being elimination of the wand marker on the heel in the static trial, which reduced between-day variability of hindfoot motion in the transverse plane.

TL;DR: In this article, three different methods of gait event detection (toe-off and heel strike) using miniature linear accelerometers and angular velocity transducers in comparison to using standard pressure sensitive foot switches were reported.

TL;DR: The current design improves upon a previous prototype by being easier to don and doff and simpler to use and the novel controller allows naive wearers to quickly adapt to the orthosis without artificial muscle co-contraction.

TL;DR: It is suggested that altered biomechanics play a role in the genesis of ERLLP and thus should be considered in prevention and rehabilitation.

TL;DR: In CLBP patients, postural stability under challenging conditions is maintained by an increased sway in AP direction, which may underlie a dysfunction of the peripheral proprioceptive system or the central integration of proprioception information.

TL;DR: The biomechanics of changing direction while walking has been largely neglected despite its obvious relevancy to functional mobility and will provide insights driving design, therapy and intervention to increase functional navigation in amputees, the elderly and individuals with neuromuscular pathologies.

TL;DR: The combination of anatomically and technically oriented marker placement on the foot is a reliable basis for reproducible kinematic measurements and the method was shown to be viable for clinical practice.

TL;DR: Results support recent findings suggesting that children do not demonstrate adult-like use of sensory information prior to age 12 years.

TL;DR: It was found that greater asymmetry was moderately related to increased medial-lateral sway for the individuals with stroke and those with stroke with mild asymmetry had greater visual dependence than those with more severe asymmetry.

TL;DR: The development and assessment of novel detection algorithms using footswitch and accelerometer sensors on 12 healthy individuals for initial contact (IC) detection and error results are lower than in previous research on ambulatory real-time gait event detection systems.

TL;DR: Findings indicate that structural foot and ankle characteristics identified from clinical measurements can explain some key aspects of plantar loading patterns of the foot.

TL;DR: It is concluded that a feed-forward mechanism is not necessary to compensate for the long closed-loop time delay in human bipedal stance as suggested in recent literature, and that the PD controller is a good approximation of the control strategy applied by able bodied subjects during quiet stance.

TL;DR: Examination of the muscle-tendon lengths and velocities allows individuals who walk with abnormally short or slow hamstrings to be distinguished from those who do not, and thus may help to identify patients who are at risk for unsatisfactory postsurgical changes in knee extension or anterior pelvic tilt.

TL;DR: In this article, the authors evaluated the correlation between gait analysis data and clinical measurements and evaluated the combined predictive value of static and dynamic clinical measurements on gait data of children with cerebral palsy.

TL;DR: The unpredictably good performance of all patient groups under dynamic condition, which was at variance with their imbalance during quiet stance, may indicate that these patients learnt to exploit anticipatory postural strategies.

TL;DR: In this paper, the authors examined the ability of 12 persons with low back pain and 12 controls to adapt trunk and pelvis rotations and erector spinae (ES) activity to sudden changes in velocity.

TL;DR: Caution is advised in using the data to attempt to predict an individual's gait parameters due to the wide spread of data about the regression lines and it is not recommend that the data be used to extrapolate the regression data to wider speed ranges.

TL;DR: Detrended fluctuation analysis showed that there were long range correlations present in the stride interval time series and these correlations followed a quasi U-shaped function, with the minimum at the preferred running speed.

TL;DR: Hip abduction angles and foot placement, not lateral trunk flexion influence trunk orientation, and therefore may guide the development of ACL prevention strategies.

TL;DR: It is concluded that standards for EMG activity and joint angle trajectories should only be compared when the training is done with velocities higher than 2.5 km h(-1) and less than 50% body weight unloading.

TL;DR: The findings of this study further support the findings of previous studies indicating that orthoses improve specific gait parameters compared to barefoot walking (velocity, step length, first and second ankle rocker, sagittal knee and hip ROM).

TL;DR: The results support previous suggestions that muscle mechanical energy expenditure is an important determinant for the preferred gait mode at a given speed.

TL;DR: The Dynamic method provided superior results in comparison to the KAD and TEA-based methods and thus represents an attractive solution for orientating the knee joint flexion-extension axis for purposes of quantitative gait analysis.

TL;DR: Differences in ability to recover balance between young and elderly women associate with variables related to strength and speed of response, and that exercise-based fall prevention programs should include balance and agility training, in addition to strength training.

TL;DR: This study supports previous results that suggested a tighter coupling exists at the intralimb level, leaving the majority of gait adaptations to occur at the interlimb level, where CRP as assessed through both cross-correlation and RMS measures changed.

TL;DR: Overall, carrying a backpack causes similar sagittal plane changes in posture and balance in both normal and AIS groups, and load limit recommendations based on normal subjects should not be applicable to subjects with AIS.

TL;DR: Within-day repeatability is generally greater than between- day repeatability, and having subjects run at a standardized speed may not be as important as previously thought.

TL;DR: It can be concluded that the use of an inverted pendulum model provides the possibility to estimate spatio-temporal gait parameters in children as well as in adults.

TL;DR: This study implies that the conventional concept of postoperative partial weight bearing starting from 200 N and a stepwise increase of the load level until full weight bearing is not valid during clinical practice.
