Falls in the elderly represent a major community and public health problem [Heinrich, 2010]. Stability of locomotion is one of the more important factors for the clinicians to look for during assessment procedure [Hurmuzlu, 1994]. Many stability indices have been proposed for clinical application; some authors applied orbital stability analysis (via Maximum Floquet multipliers, maxFM) to biomechanics with promising results [Dingwell, 2007], but still the use of this technique in the assessment of fall risk has been deemed controversial [Hamacher, 2011]. The possibility to obtain reliable orbital stability measures from a light portable device such as a single inertial sensor could fasten the acquisition procedure, but still it is not clear how experimental characteristics affect the results. Simulations represent a powerful tool to test reliability of results. The aim of this study was to compare orbital stability results coming from acceleration data of a stable walking model to experimental results obtained with the same implementation.

Abstract: | Falls in the elderly represent a major community and public health problem [Heinrich, 2010]. Stability of locomotion is one of the more important factors for the clinicians to look for during assessment procedure [Hurmuzlu, 1994]. Many stability indices have been proposed for clinical application; some authors applied orbital stability analysis (via Maximum Floquet multipliers, maxFM) to biomechanics with promising results [Dingwell, 2007], but still the use of this technique in the assessment of fall risk has been deemed controversial [Hamacher, 2011]. The possibility to obtain reliable orbital stability measures from a light portable device such as a single inertial sensor could fasten the acquisition procedure, but still it is not clear how experimental characteristics affect the results. Simulations represent a powerful tool to test reliability of results. The aim of this study was to compare orbital stability results coming from acceleration data of a stable walking model to experimental results obtained with the same implementation. |
