While studies have reported reductions in metabolic costs, increased gait speeds, and improvements in clinical test scores, a comprehensive analysis of electromyography (EMG) signals and joint kinematics is warranted because the recruitment of appropriate muscle groups during physiological movement patterns facilitates effective motor learning. Here, we compared the lower limb joint kinematics and EMG patterns while wearing the Myosuit with that of unassisted conditions when performing level overground and incline treadmill gait. The level overground gait sessions (seven healthy subjects) were performed at self-selected speeds and the incline treadmill gait sessions (four healthy subjects) were performed at 2, 3, 4, and 5 km\/h. In order to evaluate how the user is assisted, we conducted a biomechanical analysis according to the three major gait tasks: weight acceptance (WA), single-limb support, and limb advancement. The results from the gait sessions suggest that Myosuit not only well preserves the users\u2019 natural patterns, but more importantly reduce knee extensor demand during the WA phase for both level and incline gait.<\/jats:p>","DOI":"10.3390\/s22166127","type":"journal-article","created":{"date-parts":[[2022,8,17]],"date-time":"2022-08-17T03:15:27Z","timestamp":1660706127000},"page":"6127","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Biomechanical Analysis Suggests Myosuit Reduces Knee Extensor Demand during Level and Incline Gait"],"prefix":"10.3390","volume":"22","author":[{"given":"Jaewook","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Korea University College of Medicine, Seoul 02841, Korea"}]},{"given":"Yekwang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Korea University College of Medicine, Seoul 02841, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6252-5310","authenticated-orcid":false,"given":"Seonghyun","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Korea University College of Medicine, Seoul 02841, Korea"}]},{"given":"Seung-Jong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Korea University College of Medicine, Seoul 02841, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1451","DOI":"10.1136\/bjsports-2020-102955","article-title":"World Health Organization 2020 Guidelines on Physical Activity and Sedentary Behaviour","volume":"54","author":"Bull","year":"2020","journal-title":"Br.
