Full text peer-reviewed publications were included if they assessed the measurement properties (validity, reliability and\/or responsiveness) of at least one STS test among community-dwelling people with COPD. We searched six databases and imported results into Covidence where title\/abstract screening and full text selection was completed independently and in duplicate. Extraction was conducted independently and in duplicate using the COSMIN extraction file. We assessed study risk of bias (very good, adequate, doubtful or inadequate), measurement property quality (sufficient, indeterminate or insufficient) and overall certainty of evidence (high, moderate, low or very low) using the COSMIN recommended tools.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We assessed 2577 titles\/abstracts and 102 full texts for inclusion; 30 publications met eligibility.

Where assessed, reliability was sufficient for the 1\u2009min, the 5-repetition and the 30\u2009s STS tests. Only the 1\u2009min STS test had high-quality evidence of sufficient construct validity, while the 30\u2009s STS test was the sole test with at least moderate quality evidence of sufficient responsiveness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The 1\u2009min STS test has the most robust measurement properties for cross-sectional assessments while the 30\u2009s STS test is more robust to assess change.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/thorax-2025-223967","type":"journal-article","created":{"date-parts":[[2025,12,12]],"date-time":"2025-12-12T10:35:30Z","timestamp":1765535730000},"page":"581-590","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Measurement properties of the sit-to-stand test in community-dwelling people with chronic obstructive pulmonary disease: a COSMIN systematic review"],"prefix":"10.1136","volume":"81","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4979-9098","authenticated-orcid":false,"given":"Christopher","family":"Farley","sequence":"first","affiliation":[{"name":"School of Rehabilitation Science, McMaster University Faculty of Health Sciences, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anastasia N L","family":"Newman","sequence":"additional","affiliation":[{"name":"School of Rehabilitation Science, McMaster University Faculty of Health Sciences, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stuart M","family":"Phillips","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, McMaster University Faculty of Science, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenna","family":"Smith-Turchyn","sequence":"additional","affiliation":[{"name":"School of Rehabilitation Science, McMaster University Faculty of Health Sciences, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6080-5052","authenticated-orcid":false,"given":"Dina","family":"Brooks","sequence":"additional","affiliation":[{"name":"School of Rehabilitation Science, McMaster University Faculty of Health Sciences, Hamilton, Ontario, Canada"},{"name":"Respiratory Research, West Park Healthcare Centre, Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2025,12,12]]},"reference":[{"key":"2026051403202035000_81.6.581.1","unstructured":"Global Initiative for Chronic Obstructive Lung Disease .
