Emotions are known to influence walking kinematics and speed, but the effect of different emotions on knee mechanics is unclear. To test this, 20 healthy participants walked while instrumented gait data was recorded. Participants initially walked naturally (baseline) and then acting 4 emotional walking conditions: <jats:italic>Anger<\/jats:italic>, <jats:italic>Happy<\/jats:italic>, <jats:italic>Fear<\/jats:italic>, and <jats:italic>Sad<\/jats:italic>, in randomized order. Statistical parametric mapping with an analysis of variance model determined the extent to which emotions influenced knee joint mechanics. Results indicated both the happy (<jats:italic>P<\/jats:italic>\u2009=\u2009.009) and sad (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001) condition resulted in lower knee adduction moment compared with baseline. Walking both happy and sad also resulted in walking speed changes from baseline (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001). A secondary analysis of covariance model with speed as the covariate indicated no significant effect of emotional condition on knee adduction moment (<jats:italic>P<\/jats:italic>\u2009&gt;\u2009.05), which suggests that the changes from baseline can be attributed to the changes in walking speed. Decreased knee adduction is associated with reduced osteoarthritis progression and increased knee function, suggesting that walking while acting different emotions, specifically happy and sad, may moderate knee osteoarthritis risk.<\/jats:p>","DOI":"10.1123\/jab.2024-0051","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T10:10:50Z","timestamp":1742551850000},"page":"233-240","source":"Crossref","is-referenced-by-count":0,"title":["Walking While Acting Sad and Happy Emotions Influences Risk Factors of Knee Osteoarthritis"],"prefix":"10.1123","volume":"41","author":[{"given":"Samantha J.","family":"Snyder","sequence":"first","affiliation":[{"name":"Department of Kinesiology, University of Maryland, College Park, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth M.","family":"Bell","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, University of Maryland, College Park, MD, USA"},{"name":"Department of Kinesiology, Towson University, Towson, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SeungJun","family":"Oh","sequence":"additional","affiliation":[{"name":"Convergence and Open Sharing System in BioHealth Sciences, Sangmyung University, Jongno-gu, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hossein","family":"Ehsani","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, University of Maryland, College Park, MD, USA"},{"name":"Neuroscience and Cognitive Science Program, University of Maryland, College Park, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Archit","family":"Kambhamettu","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Maryland, College Park, MD, USA"},{"name":"Department of Computer Science, University of Maryland, College Park, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byeol","family":"Kim","sequence":"additional","affiliation":[{"name":"Seoul National University, Gwanak-gu, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aniket","family":"Bera","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Maryland, College Park, MD, USA"},{"name":"Department of Computer Science, Purdue University, West Lafayette, IN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ross H.","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, University of Maryland, College Park, MD, USA"},{"name":"Department of Mechanical Engineering, Kyung Hee University, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae Kun","family":"Shim","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, University of Maryland, College Park, MD, USA"},{"name":"Department of Mechanical Engineering, Kyung Hee University, Seoul, South Korea"},{"name":"Fischell Department of Bioengineering, University of Maryland, College Park, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"8","key":"r1","series-title":"Osteoarthr Cartil","doi-asserted-by":"publisher","first-page":"1233","DOI":"10.1016\/j.joca.2015.03.036","article-title":"Call for standardized definitions of osteoarthritis and risk stratification for clinical trials and clinical use","volume":"23","author":"Kraus VB","year":"2015","unstructured":"Kraus VB, Blanco FJ, Englund M, Karsdal MA, Lohmander LS.
