This study aimed to determine the validity of a wearable gait sensor system for measuring lower-limb kinematics during the TUG test. Ten young healthy participants were enrolled, and lower-limb kinematics during the TUG test were assessed using a wearable gait sensor system and a standard optical motion analysis system. The angular velocities of the hip, knee, and ankle joints in sit-to-stand and turn-to-sit phases were significantly correlated between the two motion analysis systems (R = 0.612\u20130.937). The peak angles and ranges of motion of hip, knee, and ankle joints in the walking-out and walking-in phases were also correlated in both systems (R = 0.528\u20130.924). These results indicate that the wearable gait sensor system is useful for evaluating lower-limb kinematics not only during gait, but also during the TUG test.<\/jats:p>","DOI":"10.3390\/s24196296","type":"journal-article","created":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T07:19:37Z","timestamp":1727680777000},"page":"6296","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Validity of Wearable Gait Analysis System for Measuring Lower-Limb Kinematics during Timed Up and Go Test"],"prefix":"10.3390","volume":"24","author":[{"given":"Yoshiaki","family":"Kataoka","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"},{"name":"Department of Rehabilitation, Health Sciences University of Hokkaido Hospital, Sapporo 002-8072, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0174-7416","authenticated-orcid":false,"given":"Tomoya","family":"Ishida","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9371-9361","authenticated-orcid":false,"given":"Satoshi","family":"Osuka","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5047-3437","authenticated-orcid":false,"given":"Ryo","family":"Takeda","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Hokkaido University, Sapporo 060-8628, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3210-8003","authenticated-orcid":false,"given":"Shigeru","family":"Tadano","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Yamada","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Hokkaido University, Sapporo 060-8628, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0317-8088","authenticated-orcid":false,"given":"Harukazu","family":"Tohyama","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, Sapporo 060-0812, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,29]]},"reference":[{"key":"ref_1","unstructured":"Office of Disease Prevention and Health Promotion (2010). 2020 Topics & Objectives: Older Adults."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s00776-007-1202-6","article-title":"\u201csuper-aged\u201d society and the \u201clocomotive syndrome\u201d","volume":"13","author":"Nakamura","year":"2008","journal-title":"J.
