This paper reviews the research progress of lower-limb squat assistive wearable devices, with a focus on classification methods, research outcomes, and products from both domestic and international markets. It also analyzes the key technologies involved in their development, such as mechanical mechanisms, control strategies, motion sensing, and effectiveness validation. From an industrial design perspective, the paper also explores the future prospects of lower-limb squat assistive wearable devices in four key areas: multi-signal sensing, intelligent control, human\u2013machine collaboration, and experimental validation. Finally, the paper discusses future development trends in this field.<\/jats:p>","DOI":"10.3390\/biomimetics10050258","type":"journal-article","created":{"date-parts":[[2025,4,22]],"date-time":"2025-04-22T20:11:48Z","timestamp":1745352708000},"page":"258","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Research Status and Development Trend of Lower-Limb Squat-Assistant Wearable Devices"],"prefix":"10.3390","volume":"10","author":[{"given":"Lin","family":"Li","sequence":"first","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zehan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Industrial Design, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Industrial Design, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanping","family":"Qu","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinqin","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xupeng","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Precision Instrument Engineering, Xi\u2019an University of Technology, Xi\u2019an 710048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"233","DOI":"10.1016\/0003-6870(87)90010-X","article-title":"Standardised Nordic questionnaires for theanalysis of musculoskeletal symptoms1","volume":"18","author":"Kuorinka","year":"1987","journal-title":"Appl.
