However, large population-based studies assessing gait parameters in various gait tasks are lacking. &lt;b&gt;&lt;i&gt;Objective:&lt;\/i&gt;&lt;\/b&gt; We investigated the relationship of age, the use of mobility aids and being fitted with an endoprosthesis with selected gait parameters, assessed in different walking tasks. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; In the population-based KORA-Age study, data from 907 men and women aged 65-91 years were obtained using the validated electronic walkway system GAITRite, which quantifies spatiotemporal gait parameters in the measurement range of a 488 \u00d7 61 cm walkway mat. Participants completed three walking tasks at different speeds (normal, slow and fast) and a fourth walking task at normal speed with the additional task of counting backwards (dual-task walking). Additionally, the impact of endoprostheses (hip or knee) and mobility aids was assessed. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; The highest relative age-related decline for velocity was observed during dual-task walking (26.1% for men and 23.4% for women) and for step length during fast walking (20.2 and 14.4%) when comparing participants aged &lt;70 years with those aged \u226585 years. Weaker performances for velocity, cadence and step length were observed among women with knee or hip endoprostheses (fast walking speed) (p &lt; 0.05). Across all walking tasks, significant differences between mobility aid users and nonusers were observed for velocity and step length among both men and women (p &lt; 0.05). &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; A decline in gait performance is most notable in fast speed and dual-task walking, in age-related endoprosthesis and mobility aid analyses. The marked relative decrease in gait parameters in these difficult gait tasks may be attributed to lacking resources for compensation among the elderly.<\/jats:p>","DOI":"10.1159\/000342206","type":"journal-article","created":{"date-parts":[[2012,11,2]],"date-time":"2012-11-02T13:49:03Z","timestamp":1351864143000},"page":"165-173","source":"Crossref","is-referenced-by-count":18,"title":["Decline in Gait Performance Detected by an Electronic Walkway System in 907 Older Adults of the Population-Based KORA-Age Study"],"prefix":"10.1159","volume":"59","author":[{"given":"Christine S.","family":"Autenrieth","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Karrasch","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margit","family":"Heier","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lukas","family":"Gorzelniak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl-Heinz","family":"Ladwig","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annette","family":"Peters","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angela","family":"D\u00f6ring","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2012,11,1]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1093\/geront\/37.4.433"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1093\/geront\/42.6.727"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3949\/ccjm.72.7.586"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1093\/geronj\/49.3.M97"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159\/000235905"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2007.05.016"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/63.2.165"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afp250"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2006.06.003"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2007.11.010"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s00776-008-1285-8"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2009.06.009"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2288-10-36"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1053\/apmr.2001.19778"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2004.10.005"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291700033183"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1159\/000255464"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1590\/S1413-35552011000200007"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/S0883-5403(03)00152-9"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.archger.2008.02.004"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2009.02612.x"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(97)24009-2"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afl084"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afp093"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2004.11.005"}],"container-title":["Gerontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/342206","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/342206","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:44:52Z","timestamp":1745433892000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000342206"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,11,1]]},"references-count":25,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2013,2,1]]},"published-print":{"date-parts":[[2013,2,25]]}},"URL":"https:\/\/doi.org\/10.1159\/000342206","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.5123929","asserted-by":"subject"}]},"ISSN":["0304-324X","1423-0003"],"issn-type":[{"value":"0304-324X","type":"print"},{"value":"1423-0003","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,11,1]]}}}
