Low vision affects dynamic stability of gait [PDF]

Gait & Posture, 2010
The objective of this study was to demonstrate specific differences in gait patterns between those with and without a visual impairment. We performed a biomechanical analysis of the gait pattern of young adults (27 ± 13 years old) with a visual impairment (n=10) in an uncluttered environment and compared it to the gait pattern of age matched controls ...

On the gait stability of biped machines

IEEE Transactions on Automatic Control, 1970
The control and stability properties of legged machines in locomotion are considered. The general stability of all such machines is separated into three categories: stability of the body's orientation with respect to earth; stability of the body's trajectory; stability of the gait. The control laws for a fully dynamic system with six degrees of freedom

Biped walking stabilization based on gait analysis

2012 IEEE International Conference on Robotics and Automation, 2012
This paper describes a walking stabilization control based on gait analysis for a biped humanoid robot. We have developed a human-like foot mechanism mimicking the medial longitudinal arch to clarify the function of the foot arch structure. To evaluate the arch function through walking experiments using a robot, a walking stabilization control should ...

Stability and harmony of gait in children with cerebral palsy

Research in Developmental Disabilities, 2012
The aim of this study was to quantitatively assess the stability and harmony of gait in children with cerebral palsy. Seventeen children with spastic hemiplegia due to cerebral palsy (5.0±2.3 years old) who were able to walk autonomously and seventeen age-matched children with typical development (5.7±2.5 years old, p=0.391) performed a 10-m walking ...

Influence of multiple sclerosis on dynamic gait stability

Journal of Biomechanics, 2020
Falls are a serious health threat for people with multiple sclerosis (MS). Dynamic gait stability has been identified as a key risk factor of falls. The development of effective interventions for preventing falls requires a sound understanding of how MS affects dynamic gait stability.

Wireless gyroscope suit for gait stability estimation

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
Gait stability is primary in assessing individuals with high risk of falling, particularly the elderly. Custom made self-adjustable wireless gyroscope suit is used as a sensing device to quantify gait stability. A nonlinear time series analysis i.e. maximum Lyapunov exponent (λ*) was employed to estimate the short term and long term stability and it is

Influence of single and dual tasks on gait stability and gait speed in the elderly

Zeitschrift für Gerontologie und Geriatrie, 2017
Background Gait stability during dual tasks is important for elderly persons, especially for elderly individuals in need of care. A study was conducted to assess gait stability by using Lyapunov exponents (λS) during single task and dual task conditions in independently living elderly people (Go-Goes) and elderly people in need of care (No-Goes ...

[Subjective Gait Stability in the Elderly].

Zeitschrift fur Gerontologie und Geriatrie, 2019
It can be assumed that the feeling of gait stability or gait instability in the elderly may be independent of a possible fear of falling or a history of falling when walking. Up to now, there has been a lack of spatiotemporal gait parameters for older people who subjectively feel secure when walking.The aim of the study is to analyse the distribution ...

Stability of gait and interlimb coordination in older adults

Journal of Neurophysiology, 2012
Most falls in older adults occur when walking, specifically following a trip. This study investigated the short- and longer term responses of young ( n = 24, 27.6 ± 4.5 yr) and older adults ( n = 18, 69.1 ± 4.2 yr) to a trip during gait at comfortable speed and the role of interlimb coordination in recovery from tripping.

Biped gait stabilization via foot placement

Journal of Biomechanics, 1985
It is shown that stable biped gaits can be achieved by discrete foot placement based on feedback of information available at the time of foot placement. The model, developed by Townsend (1981, J. Biomechanics 14, p. 727) to evaluate the coordinations of torso motions, subsumes most of the salient body members and motions.
