In this paper, a comparison is provided among different strategies to analyze postural sway, with the aim of detecting unstable postural status in standing condition as precursors of potential falls. Three approaches are considered: (i) a time-based features threshold algorithm, (ii) a time-based features Neuro-Fuzzy inference system, and (iii) a Neuro-Fuzzy inference fed by Discrete-Wavelet-Transform-based features. The analysis was performed across a wide dataset and exploited performance indexes aimed at assessing the accuracy and the reliability of predictions provided by the above-mentioned strategies. The results obtained demonstrate valuable performances of the three considered strategies in correctly distinguishing among stable and unstable postural status. However, the analysis of robustness against noisy data highlights better performance of Neuro-Fuzzy inference systems with respect to the threshold-based algorithm.<\/jats:p>","DOI":"10.3390\/s22197106","type":"journal-article","created":{"date-parts":[[2022,9,21]],"date-time":"2022-09-21T00:08:09Z","timestamp":1663718889000},"page":"7106","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Comparison among Different Strategies to Detect Potential Unstable Behaviors in Postural Sway"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5099-6131","authenticated-orcid":false,"given":"Bruno","family":"And\u00f2","sequence":"first","affiliation":[{"name":"Department of Electric Electronic and Information Engineering, DIEEI, University of Catania, 95125 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salvatore","family":"Baglio","sequence":"additional","affiliation":[{"name":"Department of Electric Electronic and Information Engineering, DIEEI, University of Catania, 95125 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3079-9071","authenticated-orcid":false,"given":"Salvatore","family":"Graziani","sequence":"additional","affiliation":[{"name":"Department of Electric Electronic and Information Engineering, DIEEI, University of Catania, 95125 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincenzo","family":"Marletta","sequence":"additional","affiliation":[{"name":"Department of Electric Electronic and Information Engineering, DIEEI, University of Catania, 95125 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valeria","family":"Dibilio","sequence":"additional","affiliation":[{"name":"Department of Medical, Surgical Sciences and Advanced Technologies \u201cGF Ingrassia\u201d, University of Catania, 95100 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni","family":"Mostile","sequence":"additional","affiliation":[{"name":"Department of Medical, Surgical Sciences and Advanced Technologies \u201cGF Ingrassia\u201d, University of Catania, 95100 Catania, Italy"},{"name":"Oasi Research Institute\u2014IRCCS, 94018 Troina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Zappia","sequence":"additional","affiliation":[{"name":"Department of Medical, Surgical Sciences and Advanced Technologies \u201cGF Ingrassia\u201d, University of Catania, 95100 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"ref_1","unstructured":"(2022, May 01).
