Markerless motion capture may provide a more flexible option, though its agreement in constrained environments compared with traditional spaces is not well established. This study compared a 10-camera markerless system deployed in a hallway with a traditional 8-camera laboratory setup. Twenty-five healthy adults (15 females, 10 males; age 34 [16]\u00a0y) completed quiet standing, 60\u00a0seconds of self-selected walking, and 5-repetition sit-to-stand tasks at both sites on the same day. Three-dimensional pose estimates were processed to calculate alignment during standing, lower-limb joint kinematics during walking, and trunk flexion during sit-to-stand. Agreement within and between sites was assessed using Pearson correlations, root mean square error, Bland Altman limits of agreement, and intraclass correlation coefficients. Standing and walking outcomes showed excellent agreement (intraclass correlation coefficients\u2009\u2265\u2009.97; root mean square error\u2009&lt;\u20092.3\u00b0; mean differences\u2009&lt;\u20091.1\u00b0). Sit-to-stand was more variable (limits of agreement 12\u00b0\u201320\u00b0) but remained highly reliable (intraclass correlation coefficients\u2009&gt;\u2009.96). These findings indicate that a constrained markerless setup can yield kinematic data comparable to a laboratory arrangement, suggesting potential for broader use of markerless approaches in diverse environments.<\/jats:p>","DOI":"10.1123\/jab.2025-0265","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T16:17:12Z","timestamp":1770913032000},"page":"183-191","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating the Agreement of Markerless Motion Capture for Joint Angle Estimation in a Constrained Hallway Setting Compared With a Traditional Laboratory Setting"],"prefix":"10.1123","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1976-417X","authenticated-orcid":true,"given":"Matthew","family":"Ruder","sequence":"first","affiliation":[{"name":"Department of Kinesiology, McMaster University, Hamilton, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6223-2996","authenticated-orcid":true,"given":"Vincenzo E.","family":"Di Bacco","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, McMaster University, Hamilton, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9065-8129","authenticated-orcid":true,"given":"Jereme","family":"Outerleys","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering, Queen\u2019s University, Kingston, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monica","family":"Malek","sequence":"additional","affiliation":[{"name":"Research Institute of St. Joseph\u2019s Hamilton, Hamilton, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9889-7570","authenticated-orcid":true,"given":"Elise","family":"Laende","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering, Queen\u2019s University, Kingston, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0872-0532","authenticated-orcid":true,"given":"Fatima","family":"Gafoor","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, McMaster University, Hamilton, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2861-9636","authenticated-orcid":true,"given":"Kim","family":"Madden","sequence":"additional","affiliation":[{"name":"Research Institute of St. Joseph\u2019s Hamilton, Hamilton, ON, Canada"},{"name":"Department of Surgery, McMaster University, Hamilton, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4692-819X","authenticated-orcid":true,"given":"Anthony","family":"Adili","sequence":"additional","affiliation":[{"name":"Research Institute of St. Joseph\u2019s Hamilton, Hamilton, ON, Canada"},{"name":"School of Biomedical Engineering, McMaster University, Hamilton, ON, Canada"},{"name":"Department of Surgery, McMaster University, Hamilton, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1638-0557","authenticated-orcid":true,"given":"Kevin","family":"Deluzio","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering, Queen\u2019s University, Kingston, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4268-3618","authenticated-orcid":true,"given":"Dylan","family":"Kobsar","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, McMaster University, Hamilton, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"14","key":"r1","series-title":"J Biomech","doi-asserted-by":"publisher","first-page":"3868","DOI":"10.1016\/j.jbiomech.2015.09.033","article-title":"New insight in the relationship between regional patterns of knee cartilage thickness, osteoarthritis disease severity, and gait mechanics","volume":"48","author":"Erhart-Hledik JC","year":"2015","unstructured":"Erhart-Hledik JC, Favre J, Andriacchi TP.
