However, there are not many databases that provide electroencephalography (EEG) data during the use of a lower-limb exoskeleton. The current paper presents a database designed with an experimental protocol aiming to assess not only motor imagery during the control of the device, but also the attention to gait on flat and inclined surfaces. The research was conducted as an EUROBENCH subproject in the facilities sited in Hospital Los Madro\u00f1os, Brunete (Madrid). The data validation reaches accuracies over 70% in the assessment of motor imagery and attention to gait, which marks the present database as a valuable resource for researches interested on developing and testing new EEG-based BMIs.<\/jats:p>","DOI":"10.1038\/s41597-023-02243-7","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T03:30:40Z","timestamp":1685676640000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["An EEG database for the cognitive assessment of motor imagery during walking with a lower-limb exoskeleton"],"prefix":"10.1038","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4269-1554","authenticated-orcid":false,"given":"Mario","family":"Ortiz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis","family":"de la Ossa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7806-5248","authenticated-orcid":false,"given":"Javier","family":"Juan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8057-5952","authenticated-orcid":false,"given":"Eduardo","family":"I\u00e1\u00f1ez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8767-3395","authenticated-orcid":false,"given":"Diego","family":"Torricelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6116-6256","authenticated-orcid":false,"given":"Jes\u00fas","family":"Tornero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 M.","family":"Azor\u00edn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,6,2]]},"reference":[{"key":"2243_CR1","doi-asserted-by":"publisher","first-page":"189","DOI":"10.3389\/frobt.2022.951663","volume":"9","author":"A Remazeilles","year":"2022","unstructured":"Remazeilles, A. et al.
