However, many of these devices have not yet been fully validated. The aim of this study was to assess the concurrent validity and relative reliability of the RunScribe\u2122 system for measuring spatiotemporal gait parameters during walking. A total of 460 participants (age: 36 \u00b1 13 years; height: 173 \u00b1 9 cm; body mass: 70 \u00b1 13 kg) were asked to walk on a treadmill at 5 km\u00b7h\u22121. Spatiotemporal parameters of step frequency (SF), step length (SL), step time (ST), contact time (CT), swing time (SwT), stride time (StT), stride length (StL) and normalized stride length (StL%) were measured through RunScribe\u2122 and OptoGait\u2122 systems. Bland\u2013Altman analysis indicated small systematic biases and random errors for all variables. Pearson correlation analysis showed strong correlations (0.70\u20130.94) between systems. The intraclass correlation coefficient supports these results, except for contact time (ICC = 0.64) and swing time (ICC = 0.34). The paired t-test showed small differences in SL, StL and StL% (\u22640.25) and large in CT and SwT (1.2 and 2.2, respectively), with no differences for the rest of the variables. This study confirms the accuracy of the RunScribe\u2122 system for assessing spatiotemporal parameters during walking, potentially reducing the barriers to continuous gait monitoring and early detection of gait issues.<\/jats:p>","DOI":"10.3390\/s24237825","type":"journal-article","created":{"date-parts":[[2024,12,9]],"date-time":"2024-12-09T11:16:48Z","timestamp":1733743008000},"page":"7825","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Concurrent Validity and Relative Reliability of the RunScribe\u2122 System for the Assessment of Spatiotemporal Gait Parameters During Walking"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-4208-8196","authenticated-orcid":false,"given":"Andr\u00e9s","family":"R\u00e1fales-Perucha","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Universidad San Jorge, Villanueva de G\u00e1llego, 50830 Zaragoz, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-5088-3061","authenticated-orcid":false,"given":"Elisa","family":"Bravo-Vi\u00f1uales","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Universidad San Jorge, Villanueva de G\u00e1llego, 50830 Zaragoz, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4351-1383","authenticated-orcid":false,"given":"Alejandro","family":"Molina-Molina","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Universidad San Jorge, Villanueva de G\u00e1llego, 50830 Zaragoz, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5551-6037","authenticated-orcid":false,"given":"Antonio","family":"Cart\u00f3n-Llorente","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Universidad San Jorge, Villanueva de G\u00e1llego, 50830 Zaragoz, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3804-1345","authenticated-orcid":false,"given":"Silvia","family":"Cardiel-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Universidad San Jorge, Villanueva de G\u00e1llego, 50830 Zaragoz, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8492-9244","authenticated-orcid":false,"given":"Luis E.","family":"Roche-Seruendo","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Universidad San Jorge, Villanueva de G\u00e1llego, 50830 Zaragoz, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1098","DOI":"10.1093\/tbm\/ibz198","article-title":"A Systematic Review of Physical Activity and Quality of Life and Well-Being","volume":"10","author":"Marquez","year":"2020","journal-title":"Transl.
