Showing papers in "Gait & Posture in 1994"

TL;DR: There was a significant increase in peak pressure under the heel and the medial part of the forefoot and a significant decrease under the midfoot and lateral forefoot with increasing walking speed, suggesting an effect of a medialization of the loading pattern.

TL;DR: The elderly approached maximum voluntary excursion in a less controlled manner exhibiting greater variability in their lean paths, and had greater range of oscillations at their maximum voluntaryexcursion.

TL;DR: A ‘top-down’ anticipatory control was demonstrated which stabilized the head first, then the cervical level, the thoracic level, and finally the lumbar level, which was argued that this balance control was anticipatory and not reflex.

TL;DR: In this article, the pattern of development of open-loop and closed-loop postural control in young children was investigated, showing a distinct age-related change in postural velocity in both feet together and feet heel-to-toe stances.

TL;DR: In this article, a comparison of path of motion and range of motion revealed a high correlation for abduction and adduction and plantarflexion and dorsiflexion, which is associated with the decrease in muscle strength with increasing age.

TL;DR: In this article, the peak horizontal and vertical momenta were measured among 16 young and 16 older adults with the aid of a motion analysis system and the results revealed a between-group similarity in the horizontal location of the centre of mass at the time of takeoff, and the magnitude and timing of peak horizontal momentum of the center of mass.

TL;DR: This approach to the analysis of the sit-stand-sit movement cycle in which performance can be described and quantified should provide researchers with a means of standardizing and formalizing the reporting of research findings in a manner similar to that from which gait analysis has benefited greatly.

TL;DR: Footwear, particularly the training shoes, was found to attenuate the signals from the footswitches leading to differences typically of the order of 0.04 s between the durations of the temporal gait phases calculated from the forceplate data.

TL;DR: In this article, the authors examined the interactive effects of the base of support (number of feet; sole versus toes), visual information and skill level on the stability of adults in certain postural balance tasks.

TL;DR: Characteristic gait patterns in children with lumbosacral level myelomeningocele are distinguished, showing that deviations in the patterns were most apparent at the pelvis and knee and were related to muscle weakness.

TL;DR: In this article, a three-dimensional biomechanical model was used to determine upper extremity kinematics of 16 male subjects with low-level paraplegia while performing wheelchair propulsion (WCP).

TL;DR: It was concluded that clear temporospatial and postural changes resulted from load carriage, some of the changes being load dependent.

TL;DR: It was concluded that the measurement system can provide accurate, consistent, and reliable information on patterns of acceleration and displacement, and definitive data on temporal and spatial parameters and the relationship between them.

TL;DR: In this paper, the effects of viscoelastic shoe shock absorbers on attenuation and dissipation of high-heel-shoe-generated shock waves were also analyzed.

TL;DR: In this paper, a theoretical approach to the optimization of shank-foot inertial properties was developed in which a single dimensionless inertial parameter allowed examination of the required joint power of the prosthetic knee during swing phase with normal kinematics.

TL;DR: An improved hand-control module providing voluntary control over functional-electrical-stimulation-restored walking pattern was developed, and noticeable effects of functional electrical stimulation during the push-off phase were particularly evident in the vertical ground reaction force and horizontal hip joint displacement.

TL;DR: This small study showed that decreased plantarflexion results in decreased ability to propulse forward at push-off, and limited propulsion found in the children with clubfeet may be caused by the current standard of treatment of the clubfoot, which includes lengthening the Achilles tendon.

TL;DR: In this article, the performance of an energy-storing prosthetic foot fabricated from composite materials, known as the Lambda Foot, and the conventional SACH foot was compared by gait analysis.

TL;DR: It was concluded that the developed three-dimensional videometric method was reliable and that very small deviations of spinal alignment and trunk rotation as well as leg and arm positions could be detected by the system.

TL;DR: It is suggested that the tibialis anterior is more sensitive than the gastrocnemius muscle to a visual stimulus to aVisual flow pattern, and little adaptational changes in EMG pattern occurred between the second and fifth sway cycles after presentation of the optical flow pattern.

TL;DR: This poster presents a poster presented at the annual meeting of the American Academy of Orthopaedic Surgeons (AAS) entitled “Preparations for Posterior Caesarean Section Arthroplasty and Trauma: Foundations of Post-operative Care and Surgeons’ Discussion.

TL;DR: This type of safety system may be valuable both for screening of patient populations during balance/walking assessment and training, and to permit perturbations without anxiety-related and unnecessary support-system effects on the patients' movements.

TL;DR: In this article, the authors developed laboratory and field test methods to simulate the motions and system responses when an individual walks on a synthetic surface such as carpet, and the heel-strike was simulated by the impact of a Clegg tester, a free-falling 2.27-kg missile, instrumented to record peak deceleration (g max ).

TL;DR: This objective investigation using in-shoe dynamic pressure measurements showed that the addition of a shank to control insole rigidity reduced the overall peak pressures under the foot.
