Does dynamic stability govern propulsive force generation in human walking?
Before succumbing to slower speeds, older adults may walk with a diminished push-off to prioritize stability over mobility. However, direct evidence for trade-offs between push-off intensity and balance control in human walking, independent of changes in speed, has remained elusive. As a critical first step, we conducted two experiments to investigate: (i) the independent effects of walking spe...
متن کاملPassive Dynamic Stability in Human Walking
INTRODUCTION As shown by McGeer (1990), the passive dynamics of the legs are sufficient to walk down a gentle slope with no external control, and no external energy input save from gravity. Here we consider different models based on passive dynamics, including actively powered models that still make use of passive dynamic principles. We consider the stability of these models, and the implicatio...
متن کاملThe Age-Associated Reduction in Propulsive Power Generation in Walking.
FRANZ,J.R.Theage-associated reduction in propulsive power generation in walking. Exerc. Sport Sci. Rev.,Vol. 44, No. 4, pp. 129–136, 2016. Propulsive power generation during push-off in walking decreases with advancing age. A common explanation is an accommodation for sarcopenia and muscle weakness. Yet, muscle strengthening often yields disappointing outcomes for walking performance. We examin...
متن کاملAssessment of Dynamic Stability During Walking in Below-knee Amputation
Purpose: Dynamic stability reduces in patients with unilateral amputation; so, it is important to recognize changes in balance during walking. This study aimed to investigate the dynamic stability of unilateral below-knee amputation during walking. Methods: The present study was a quasi-experimental study, in which 10 patients with knee amputation and 10 healthy young people participated. The ...
متن کاملDifferences between local and orbital dynamic stability during human walking.
Currently there is no commonly accepted way to define, much less quantify, locomotor stability. In engineering, "orbital stability" is defined using Floquet multipliers that quantify how purely periodic systems respond to perturbations discretely from one cycle to the next. For aperiodic systems, "local stability" is defined by local divergence exponents that quantify how the system responds to...
