We compared this automated (LiDAR\u2010based) standing\u2010start 4\u2010m gait speed test (AS\u20104MG) with automated and manual (stopwatch\u2010based) dynamic\u2010start 4\u2010m gait speed tests (AD\u20104MG and MD\u20104MG, respectively) on between\u2010method agreement, measurement repeatability, and predictive validity with functional outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A sample of 48 community\u2010dwelling adults (mean [SD], 69 [9] years) participated in this method comparison study. Participants completed a survey and a physical function assessment, from which self\u2010reported stair difficulty, handgrip strength, sit\u2010to\u2010stand performance, and gait speed (AS\u2010, AD\u2010, and MD\u20104MG) were measured.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Mean AS\u20104MG, AD\u20104MG, and MD\u20104MG were 1.12, 1.13, and 1.14\u2009m\/s, respectively, with a strong correlation (<jats:italic>r<\/jats:italic>\u2009=\u20090.94) and no systematic bias observed between AS\u20104MG and the referent AD\u20104MG. In the analyses of repeated gait measurements, coefficients of repeatability were &lt;0.20\u2009m\/s for the automated tests (0.16 and 0.18\u2009m\/s for AS\u20104MG and AD\u20104MG, respectively) but not for MD\u20104MG (0.22\u2009m\/s). Correlations between gait speed and functional measures ranged between 0.44 and 0.68 (<jats:italic>P<\/jats:italic>s\u2009&lt;\u20090.01).

The AS\u20104MG potentially allows gait measurements in confined spaces (e.g., doctor's office) where the gait speed test was previously unfeasible. <jats:bold>Geriatr Gerontol Int 2025; 25: 449\u2013453<\/jats:bold>.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ggi.15077","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T08:03:36Z","timestamp":1737360216000},"page":"449-453","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Gait speed assessment in confined spaces: Development of a novel automated 4\u2010m static\u2010start test to measure dynamic\u2010start gait speed"],"prefix":"10.1111","volume":"25","author":[{"given":"Yong\u2010Hao","family":"Pua","sequence":"first","affiliation":[{"name":"Department of Physiotherapy Singapore General Hospital  Singapore"},{"name":"Medicine Academic Programme, Duke\u2010NUS Graduate Medical School  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ross Allan","family":"Clark","sequence":"additional","affiliation":[{"name":"School of Health and Behavioural Science University of the Sunshine Coast  Sunshine Coast Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Tay","sequence":"additional","affiliation":[{"name":"Department of General Medicine (Geriatric Medicine) Sengkang General Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yee\u2010Sien","family":"Ng","sequence":"additional","affiliation":[{"name":"Department of General Medicine (Geriatric Medicine) Sengkang General Hospital  Singapore"},{"name":"Department of Rehabilitation Medicine Singapore General Hospital  Singapore"},{"name":"Geriatric Education and Research Institute  Singapore"},{"name":"Duke\u2010NUS Medical School  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaylyn Tze\u2010Theng","family":"Poh","sequence":"additional","affiliation":[{"name":"Research Office Singapore General Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salma Bte Md","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy Singapore General Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wai\u2010Chye","family":"Cheong","sequence":"additional","affiliation":[{"name":"Alice Lee Innovation Centre of Excellence (Singapore General Hospital Campus) SingHealth  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong\u2010Han","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy Singapore General Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julian","family":"Thumboo","sequence":"additional","affiliation":[{"name":"Medicine Academic Programme, Duke\u2010NUS Graduate Medical School  Singapore"},{"name":"Health Services Research &amp;
