Thirty-two patients (age: 56.84 \u00b1 9.10 years; 68.8% male) underwent an instrumental gait analysis, performed using a wearable inertial sensor before and a day after the 10-session treatment (PRE and POST sessions). The treatment consisted of 10 sessions of 20 min of walking on a treadmill while using the FDS device. The spatio-temporal parameters and the HR in the anteroposterior (AP), vertical (V), and mediolateral (ML) directions were computed from trunk acceleration data. The results showed that time had a significant effect on the spatio-temporal parameters; in particular, a significant increase in gait speed was detected. Regarding the HRs, the HR in the ML direction was found to have significantly increased (+20%), while those in the AP and V directions decreased (approximately 13%). Even if further studies are necessary, from these results, the HR seems to provide additional information on gait patterns with respect to the traditional spatio-temporal parameters, advancing the assessment of the effects of FDS devices in stroke patients.<\/jats:p>","DOI":"10.3390\/s21030921","type":"journal-article","created":{"date-parts":[[2021,1,29]],"date-time":"2021-01-29T11:34:33Z","timestamp":1611920073000},"page":"921","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Functional Electrical Stimulation for Foot Drop in Post-Stroke People: Quantitative Effects on Step-to-Step Symmetry of Gait Using a Wearable Inertial Sensor"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6020-9186","authenticated-orcid":false,"given":"Giulia","family":"Schifino","sequence":"first","affiliation":[{"name":"Rehabilitation Sciences Graduate Program, Universidade Federal de Ci\u00eancias da Sa\u00fade de Porto Alegre (UFCSPA), Porto Alegre 90050-170, Brazil"},{"name":"Movement Analysis and Rehabilitation Laboratory, Universidade Federal de Ci\u00eancias da Sa\u00fade de Porto Alegre (UFCSPA), Porto Alegre 90050-170, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6299-7254","authenticated-orcid":false,"given":"Veronica","family":"Cimolin","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9835-3629","authenticated-orcid":false,"given":"Massimiliano","family":"Pau","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Chemical and Materials Engineering, University of Cagliari, Piazza d\u2019Armi, 09123 Cagliari, Italy"}]},{"given":"Maira Jaqueline","family":"da Cunha","sequence":"additional","affiliation":[{"name":"Rehabilitation Sciences Graduate Program, Universidade Federal de Ci\u00eancias da Sa\u00fade de Porto Alegre (UFCSPA), Porto Alegre 90050-170, Brazil"},{"name":"Movement Analysis and Rehabilitation Laboratory, Universidade Federal de Ci\u00eancias da Sa\u00fade de Porto Alegre (UFCSPA), Porto Alegre 90050-170, Brazil"}]},{"given":"Bruno","family":"Leban","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Chemical and Materials Engineering, University of Cagliari, Piazza d\u2019Armi, 09123 Cagliari, Italy"}]},{"given":"Micaela","family":"Porta","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Chemical and Materials Engineering, University of Cagliari, Piazza d\u2019Armi, 09123 Cagliari, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2772-4837","authenticated-orcid":false,"given":"Manuela","family":"Galli","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7837-5855","authenticated-orcid":false,"given":"Aline","family":"Souza Pagnussat","sequence":"additional","affiliation":[{"name":"Rehabilitation Sciences Graduate Program, Universidade Federal de Ci\u00eancias da Sa\u00fade de Porto Alegre (UFCSPA), Porto Alegre 90050-170, Brazil"},{"name":"Movement Analysis and Rehabilitation Laboratory, Universidade Federal de Ci\u00eancias da Sa\u00fade de Porto Alegre (UFCSPA), Porto Alegre 90050-170, Brazil"},{"name":"Department of Physiotherapy, Universidade Federal de Ci\u00eancias da Sa\u00fade de Porto Alegre (UFCSPA), Porto Alegre 900050-170, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1821","DOI":"10.1016\/S0140-6736(09)61829-8","article-title":"Contribution of chronic diseases to disability in elderly people in countries with low and middle incomes: A 10\/66 Dementia Research Group population-based survey","volume":"374","author":"Sousa","year":"2009","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Tan, U.
