PODOSmart\u00ae system measures walking profile and gait variables in real life conditions. PODOSmart\u00ae insoles consists of wireless sensors, can be fitted into any shoe and offer the ability to measure spatial, temporal, and kinematic gait parameters. The intelligent insoles feature several sensors that detect and capture foot movements and a microprocessor that calculates gait related biomechanical data. Gait analysis results are presented in PODOSmart\u00ae platform. This study aims to present the characteristics of this tool and to validate it comparing with a stereophotogrammetry-based system. Validation was performed by gait analysis for eleven healthy individuals on a six-meters walkway using both PODOSmart\u00ae and Vicon system. Intraclass correlation coefficients (ICC) were calculated for gait parameters. ICC for the validation ranged from 0.313 to 0.990 in gait parameters. The highest ICC was observed in cadence, circumduction, walking speed, stride length and stride duration. PODOSmart\u00ae is a valid tool for gait analysis compared to the gold standard Vicon. As PODOSmart\u00ae, is a portable gait analysis tool with an affordable cost it can be a useful novel tool for gait analysis in healthy and pathological population.<\/jats:p>","DOI":"10.3390\/s21175972","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T21:47:38Z","timestamp":1630964858000},"page":"5972","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["A Novel Tool for Gait Analysis: Validation Study of the Smart Insole PODOSmart\u00ae"],"prefix":"10.3390","volume":"21","author":[{"given":"Efthymios","family":"Ziagkas","sequence":"first","affiliation":[{"name":"Department of Physical education and Sport Science, Aristotle University of Thessaloniki, 57001 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Loukovitis","sequence":"additional","affiliation":[{"name":"Department of Physical education and Sport Science, Aristotle University of Thessaloniki, 57001 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitrios Xypolias","family":"Zekakos","sequence":"additional","affiliation":[{"name":"Digitsole SAS, 54000 Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas Duc-Phu","family":"Chau","sequence":"additional","affiliation":[{"name":"Digitsole SAS, 54000 Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9156-4896","authenticated-orcid":false,"given":"Alexandros","family":"Petrelis","sequence":"additional","affiliation":[{"name":"Digitsole SAS, 54000 Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George","family":"Grouios","sequence":"additional","affiliation":[{"name":"Department of Physical education and Sport Science, Aristotle University of Thessaloniki, 57001 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"588","DOI":"10.2340\/16501977-0382","article-title":"Reliability of lower limb kinematics, mechanics and energetics during gait in patients after stroke","volume":"41","author":"Caty","year":"2009","journal-title":"J.
