A Neuro-Fuzzy Approach to Assess Postural Sway

Abstract

Assistive Technology helps to assess the daily living of frail people, and aid to detect and prevent falls. In this paper, a novel Neuro-Fuzzy paradigm is proposed that can perform the assessment of postural sway behaviors based on inertial measurements of the user dynamics. A suitable set of features is obtained from the measurements and is used to feed the assessment methodology. The proposed assessment approach provides superior results, in terms of reliability, when compared to the traditional threshold-based assessment algorithms, showing a mean reliability index in the order of 95%.
