Maximum Lyapunov exponent revisited: Long-term attractor divergence of gait dynamics is highly sensitive to the noise structure of stride intervals
Philippe Terrier, Fabienne Reynard
The local dynamic stability method (maximum Lyapunov exponent) can assess gait stability. Two variants of the method exist: the short-term divergence exponent (DE), and the long-te…
Determinants of gait stability while walking on a treadmill: a machine learning approach
Fabienne Reynard, Philippe Terrier
Dynamic balance in human locomotion can be assessed through the local dynamic stability (LDS) method. Whereas gait LDS has been used successfully in many settings and applications,…
Fractal Fluctuations in Human Walking: Comparison between Auditory and Visually Guided Stepping
Philippe Terrier
In human locomotion, sensorimotor synchronization of gait consists of the coordination of stepping with rhythmic auditory cues (auditory cueing, AC). AC changes the long-range corr…
Effect of age on the variability and stability of gait: a cross-sectional treadmill study in healthy individuals between 20 and 69 years of age
Philippe Terrier, Fabienne Reynard
Falls during walking are a major health issue in the elderly population. Older individuals are usually more cautious, work more slowly, take shorter steps, and exhibit increased st…
Local dynamic stability of treadmill walking: intrasession and week-to-week repeatability
Fabienne Reynard, Philippe Terrier
Repetitive falls degrade the quality of life of elderly people and of patients suffering of various neurological disorders. In order to prevent falls while walking, one should rely…
Nonlinear dynamics of human locomotion: effects of rhythmic auditory cueing on local dynamic stability
Philippe Terrier, Olivier Deriaz
Synchronizing steps with an external auditory stimulus (rhythmic auditory cueing (RAC) enhances gait recovery in neurological disorders. The activation of specific sensory-motor pr…
