Showing papers in "Gait & Posture in 1995"

TL;DR: The inverted pendulum model permitted us to understand the separate roles of the two mechanisms during these critical unbalancing and rebalancing periods and confirmed the critical importance of the hip abductors/adductors in balance during all phases of standing and walking.

TL;DR: The accuracy and processing time of 11 commercially available 3D camera systems were tested to evaluate their performance in clinical gait evaluation to estimate the processing time for calculating 3D coordinates from data obtained during normal gait.

TL;DR: It is shown that somatosensory function is at least as important as vision in the control of posture during quiet stance, and that the visual and vestibular systems cannot fully compensate for diminished somatoensory input.

TL;DR: In this article, the adaptive changes in the compensatory stepping response that occur with repeated exposure to the same postural perturbation were investigated using videorecord recordings, surface EMG, and ground reaction forces.

TL;DR: In this article, the authors examined the symmetry properties of 34 gait variables in a group of 31 hemiplegic subjects and found only weak evidence that symmetry plays any role in promoting speed in this subject group.

TL;DR: It can be concluded that the way step frequency and step length are controlled involuntarily varies with the employed voluntary strategies, and the different modes of walking suggest the existence of specific supraspinal influences on lower level pattern generating mechanisms.

TL;DR: Dizziness and subjective balance disturbances are frequent complaints in cervical pain syndromes of different origins and Disorders of the neck should be considered when assessing patients complaining of dizziness or vertigo.

TL;DR: Gait speed was significantly slower for the elderly than the young adults, and was used as a covariate in a multivariate analysis of covariance (MANCOVA) to detect differences between the young adult and the elderly.

TL;DR: Findings for the shoe upper indicate that decreased dorsal forces and pressures may be related to decreased upper comfort, and suggest that the measurement of pressure distribution at the foot-shoe interface could be a useful tool in identifying the causes of discomfort in footwear.

TL;DR: A conceptual framework is presented to evaluate the contributions biomechanical research has made under the three domains of residual limb discomfort and mechanical skin injury, reduced capacity to walk distances or run, and reduced endurance and fatigue.

TL;DR: It is suggested that ageing affects the spectral characteristics of postural forces used to maintain stability in the m-I direction, and not in the anterior-posterior direction.

TL;DR: In this article, the effects of treadmill frequency on the kinematic data between children and adults were observed and it was suggested that the greater amplitude of leg muscle activation of the children is required to compensate for the inertial forces acting at the body less economically than for the adults.

TL;DR: In this paper, the adaptation of leg movements to split-belt conditions was studied during treadmill walking in 10 healthy subjects, and the adaptation to differences in left and right belt speed always involved: (1) Changes in stride cycle duration.

TL;DR: Findings suggest an accentuated hemiplegic pattern but with quicker, shorter steps indicative of a cautious gait, which has been associated with compromised balance in the elderly.

TL;DR: It is concluded that hip and knee flexion in stance are tolerated well by children with low level spina bifida and control of pelvic rotation and obliquity and hip ab/adduction by functioning hip abductors appear to be the most important determinants of efficient ambulation in spina Bifida.

TL;DR: In this paper, the authors evaluated the gait responses of individuals with low vision compared to those of normal-visioned individuals when their vision is challenged by extreme levels of light.

TL;DR: Strength of the paretic lower extremity and standing balance were found consistently to be correlated with gait performance and represent appropriate targets for evaluation and treatment in patients with stroke.

TL;DR: In this article, the relationship between vertical loading and deloading rates, as well as anterior-posterior braking and propulsive force peaks, and translational impulse were investigated in hemiparetic stroke patients.

TL;DR: The results suggest that the method may offer a simple and reliable method of evaluating the efficacy of neural mechanisms involved in the maintenance of standing balance.

TL;DR: Energy consumption and blood flow allocations were studied in human subjects who were induced to stand and walk in a bent-head, bent-knee way, which is one of the different bipedal behaviours that could be considered for the posture and locomotion of Australopithecus afarensis.

TL;DR: It was concluded that fine-wire electrodes had no significant affect on muscle activity during gait as measured by surface EMG signals under normal adults under conditions in normal adults.

TL;DR: Encouraging the use of very selective EMG of the forearm musculature is important to identify the most appropriate procedure before correction of hand dysfunction, which may have important implications for the management of deformities.

TL;DR: Factors that may contribute to the effectiveness of fine postural control are discussed, including the lack of sensory feedback from the lower extremities, the possible biomechanical disadvantage of the arm in providing precorrecting movements of the body, and the comfort level exhibited by the subjects.
