This study investigated the nature of the relationship between level of disability and oxygen cost in people with chronic stroke.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Level of walking disability was measured as comfortable walking speed using the 10\u2010m Walk Test reported in m\/s with 55 ambulatory people 2\u00a0years after stroke. Oxygen cost was measured during 3 walking tasks: overground walking at comfortable speed, overground walking at fast speed, and stair walking at comfortable speed. Oxygen cost was calculated from oxygen uptake divided by distance covered during walking and reported in ml\u2219kg\n \u22121<\/jats:sup>\n \u2219m\n \u22121<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The relationship between level of walking disability and oxygen cost was curvilinear for all 3 walking tasks. One quadratic model accounted for 81% (95% CI [74, 88]) of the variance in oxygen cost during the 3 walking tasks:<\/jats:p>\n \n \n \n urn:x-wiley:13582267:media:pri1688:pri1688-math-0001<\/jats:alt-text>\n <\/jats:graphic>\n <\/jats:disp-formula>\n <\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n The oxygen cost of walking was related the level of walking disability in people with chronic stroke, such that the more disabled the individual, the higher the oxygen cost of walking; with oxygen cost rising sharply as disability became severe. An equation that relates oxygen cost during different walking tasks according to the level of walking disability allows clinicians to determine oxygen cost indirectly without the difficulty of measuring oxygen uptake directly.<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/pri.1688","type":"journal-article","created":{"date-parts":[[2017,7,3]],"date-time":"2017-07-03T06:42:49Z","timestamp":1499064169000},"source":"Crossref","is-referenced-by-count":25,"title":["Relationship between oxygen cost of walking and level of walking disability after stroke: An experimental study"],"prefix":"10.1002","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3366-1545","authenticated-orcid":false,"given":"Janaine C.","family":"Polese","sequence":"first","affiliation":[{"name":"Discipline of Physiotherapy The University of Sydney Sydney Australia"},{"name":"Department of Physical Therapy Universidade Federal de Minas Gerais Belo Horizonte Brazil"},{"name":"Department of Physical Therapy Faculdade Ci\u00eancias M\u00e9dicas de Minas Gerais Belo Horizonte Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1369-5721","authenticated-orcid":false,"given":"Louise","family":"Ada","sequence":"additional","affiliation":[{"name":"Discipline of Physiotherapy The University of Sydney Sydney Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8358-8636","authenticated-orcid":false,"given":"Luci F.","family":"Teixeira\u2010Salmela","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy Universidade Federal de Minas Gerais Belo Horizonte Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,7,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1836-9553(11)70007-8"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0004-9514(09)70008-X"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.166.1.at1102"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1590\/S0004-282X1994000100001"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/STR.0000000000000022"},{"key":"e_1_2_7_7_1","first-page":"49","article-title":"Six minute walk test: A Brazilian Standardization","volume":"18","author":"Britto R.
