Participants were 24 persons with MS (20 women; age = 44 \u00b1 12) and 24 healthy persons without MS (20 women; age = 41 \u00b1 11). The MS group was divided using the 12-item MS Walking Scale (MSWS-12) into two walking impairment subgroups: (a) minimal (<jats:italic>n<\/jats:italic> = 13, MSWS-12 \u2264 12.5) and (b) mild-moderate (<jats:italic>n<\/jats:italic> = 11, MSWS-12 &gt; 12.5). METs were measured with spirometry and step-rate with hand-tally. Steprate, height, group, the step-rate by group interaction, and the square of step-rate significantly predicted METs. At a given height, the step-rate thresholds at 3 and 6 METs were lower for persons with minimal impairment than persons without MS and even lower for persons with mild-moderate impairment. The relationship between METs and step-rate is altered in persons with MS, lowering their step-rate thresholds for activity intensity, especially for persons with MS who have higher levels of walking impairment.<\/jats:p>","DOI":"10.1123\/apaq.2013-0008","type":"journal-article","created":{"date-parts":[[2013,12,30]],"date-time":"2013-12-30T19:34:12Z","timestamp":1388432052000},"page":"4-18","source":"Crossref","is-referenced-by-count":11,"title":["Step-Rate Thresholds for Physical Activity Intensity in Persons With Multiple Sclerosis"],"prefix":"10.1123","volume":"31","author":[{"given":"Stamatis","family":"Agiovlasitis","sequence":"first","affiliation":[{"name":"1Mississippi State University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert W.","family":"Motl","sequence":"additional","affiliation":[{"name":"2University of Illinois at Urbana-Champaign"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","container-title":["Adapted Physical Activity Quarterly"],"original-title":[],"link":[{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/apaq\/31\/1\/article-p4.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.humankinetics.com\/downloadpdf\/journals\/apaq\/31\/1\/article-p4.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,19]],"date-time":"2022-05-19T17:02:03Z","timestamp":1652979723000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/apaq\/31\/1\/article-p4.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,1]]},"references-count":0,"journal-issue":{"issue":"1"},"URL":"https:\/\/doi.org\/10.1123\/apaq.2013-0008","relation":{},"ISSN":["0736-5829","1543-2777"],"issn-type":[{"value":"0736-5829","type":"print"},{"value":"1543-2777","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,1]]}}}
