The anchor-based method used the Oswestry Disability Index (ODI) and the satisfaction subscale of the Zurich Claudication Questionnaire. Receiver-operating characteristic (ROC) curve analysis was used to determine the optimal cutoff points for MCIDs for changes in the 6MWD and step count. The distribution-based method used 0.3 SD of the change scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Anchor-based MCIDs for the 6MWD were 26\u00a0m (ODI) and 35\u00a0m (walking satisfaction). The step count MCID could not be determined using the ODI but was 680 steps when anchored to satisfaction. The distribution-based method estimated MCIDs of 34\u00a0m for the 6MWD and 750 steps for step count.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Even modest improvements in walking capacity and daily step count may be meaningful to patients recovering from LSS surgery. Further research is needed to validate the MCID for daily step count however, the identified MCIDs for the 6MWD (26\u201335\u00a0m) and daily step count (680\u2013750 steps) provide practical thresholds for assessing meaningful change and can be used to inform goal setting within rehabilitation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00586-025-09085-4","type":"journal-article","created":{"date-parts":[[2025,7,15]],"date-time":"2025-07-15T09:06:55Z","timestamp":1752570415000},"page":"5690-5700","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Minimal clinically important difference of the 6-Minute walk test and daily step count at 3 months following surgery for lumbar spinal stenosis"],"prefix":"10.1007","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1863-9473","authenticated-orcid":false,"given":"Suzanne","family":"McIlroy","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yee","family":"Mah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vassilios","family":"Tahtis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abigail","family":"Beddard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lindsay","family":"Bearne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Weinman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sam","family":"Norton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,7,15]]},"reference":[{"key":"9085_CR1","doi-asserted-by":"publisher","first-page":"2143","DOI":"10.1007\/s00586-020-06339-1","volume":"29","author":"RK Jensen","year":"2020","unstructured":"Jensen RK, Jensen TS, Koes B, Hartvigsen J (2020) Prevalence of lumbar spinal stenosis in general and clinical populations: a systematic review and meta-analysis.
