Gait Stability, Variability and Complexity on Inclined Surfaces
Journal of Biomechanics, 2017This study evaluated the gait stability, variability, and complexity of healthy young adults on inclined surfaces. A total of 49 individuals walked on a treadmill at their preferred speed for 4min at inclinations of 6%, 8%, and 10% in upward (UP) and downward (DOWN) conditions, and in horizontal (0%) condition.

Comparison of gait variability and stability indices
2020 IEEE 2nd Global Conference on Life Sciences and Technologies (LifeTech), 2020Indices of variability and stability are essential in evaluating the motions of the human gait. Owing to the inconsistent results of earlier studies, the relationships among popular indices, i.e., maximum Lyapunov exponent (λ), MeanSD, and long-range correlation (α), are inconclusive.

Gait stability following concussion
Journal of Biomechanics, 2006The need to identify functional impairment following a brain injury is critical to prevent reinjury during the period of recovery. However, little is known about the effect of concussion on dynamic motor function.The purpose of this study was to examine the effect of concussion on a dynamic motor task under conditions of divided and undivided attention

Stability of an underactuated bipedal gait
Biosystems, 2007A self-excited biped walking mechanism consisting of two legs that are connected in series at the hip joint through a servomotor is studied as a cyclic system with collisions. A torque proportional to angle between the shank of the swinging leg and the vertical is seen to sustain a gait.

On the stability properties of hexapod tripod gait
IEEE Journal on Robotics and Automation, 1988Hexapod tripod gaits for straight-line motion and crab walking are derived. Mathematical relations that express the stability margin, the stride length, and the duty factor are formulated for straight-line motion and for crab walking, respectively. The derived results provide tripod gaits of the hexapond for walking with a prescribed stability margin ...

A study of the stability of generalized wave gaits
Mathematical Biosciences, 1993The wave gait has been observed in animal and insect walking and has been widely implemented in the control of walking machines. It has been proved that the wave gait possesses the optimum stability among all periodic gaits under the geometrical condition that R/P < or = 1, where R and P are respectively the stroke and pitch of a walking machine ...

Gait in stabilized hemiplegic outpatients in rehabilitation
Disability and Rehabilitation, 2003Hemiplegic patients generally expect an improvement of their gait even at 1 year after stroke. This open and prospective study was addressed to detect even subtle changes in gait characteristics in stabilized patients in rehabilitation treatment by using an opto-electronic system of analysis (ELITE).Forty-two hemiplegic patients were entered on this ...

Acquirement of stability and mobility in infant gait
Gait & Posture, 2002We examined gait development in a longitudinal and cross-sectional study in 35 infants, age range 7-70 months. We estimated walking stability from mediolateral motion of body segments and mobility from the angular displacement of joints. Motion at the shoulder, hip, knee and ankle decreased significantly over several months after the onset of walking ...

Stability analysis of wave‐crab gaits of a quadruped
Journal of Robotic Systems, 1990Abstract Crab walking is as important as forward walking as applied to walking machine control. Crab walking is especially important to a quadruped since a quadruped has a similar leg geometric layout in both longitudinal and lateral directions.

Stability is an important concept in biomechanics. It means that a mechanical system in equilibrium should resist changing its motion properties after an external perturbation. Gait is one of the most common ways of locomotion in humans. Walking is a motor action achieved by interaction of the nervous system, muscles, joints, and bones with the ...
