Nonlinear methods, like orbital stability analysis, are gaining much interest in biomechanics due to their possible application in locomotor stability assessment. Nevertheless, still the use of this technique in the assessment of fall risk has been deemed controversial; one reason could lie in the lack of a standard implementation, particularly in terms of state space composition and number of necessary strides. It is also yet not clear how experimental noise can affect stability results. The aim of this study was to explore how different analysis implementations affect stability results of a stable walking model, and the influence of simulated experimental noise on the results.

Abstract

Nonlinear methods, like orbital stability analysis, are gaining much interest in biomechanics due to their possible application in locomotor stability assessment. Nevertheless, still the use of this technique in the assessment of fall risk has been deemed controversial; one reason could lie in the lack of a standard implementation, particularly in terms of state space composition and number of necessary strides. It is also yet not clear how experimental noise can affect stability results. The aim of this study was to explore how different analysis implementations affect stability results of a stable walking model, and the influence of simulated experimental noise on the results.
