Traditional methods for assessing STS often involve costly laboratory equipment, limiting their accessibility. This study introduced an economic alternative to the standard motion capture setup. The system presented in this study used an Azure Kinect and a plantar pressure sensor mat to acquire kinematic and kinetic data simultaneously during the STS. The Kinect provided noncontact motion capture, while the pressure sensor array measured ground reaction forces. To address the Kinect\u2019s inherent limitations in capturing extremity movements and the sensor array\u2019s inability to measure tangential forces, algorithms for the correction of lower limb joints and a multisource fusion model were developed. The accuracy of the proposed system was evaluated against a gold standard Vicon motion capture system. The results indicated that the system delivered estimates comparable to reference values for joint angles (r ranging from 0.85 to 0.99), antero-posterior and vertical ground reaction forces (r ranging from 0.81 to 0.98), joint reaction forces of knee and ankle (r ranging from 0.83 to 0.90), and joint moments of hip and ankle (r ranging from 0.77 to 0.82), suggesting that the proposed system can provide vital kinematic and kinetic data for efficient STS analysis. This study offered an accessible and practical solution for monitoring and assessing mobility in various settings.<\/jats:p>","DOI":"10.1115\/1.4067981","type":"journal-article","created":{"date-parts":[[2025,2,22]],"date-time":"2025-02-22T08:49:36Z","timestamp":1740214176000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":2,"title":["A Feasible Low-Cost System for Kinematic and Kinetic Analysis of Sit-to-Stand Movement"],"prefix":"10.1115","volume":"147","author":[{"given":"Daoyuan","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Zhejiang University , Hangzhou 310027, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Tang","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, Zhejiang Hospital , Hangzhou 310013, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengqian","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Zhejiang University , Hangzhou 310027, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yichong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Zhejiang University , Hangzhou 310027, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingtao","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Zhejiang Hospital , Hangzhou 310013, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zenghui","family":"Gu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Zhejiang Hospital , Hangzhou 310013, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gangmin","family":"Ning","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Zhejiang University , Hangzhou 310027, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2025,3,5]]},"reference":[{"issue":"1","key":"2025030510393343100_bib1","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1016\/j.gaitpost.2007.10.003","article-title":"Quantitative Analysis of Sit to Stand Movement: Experimental Set-Up Definition and Application to Healthy and Hemiplegic Adults","volume":"28","year":"2008","journal-title":"Gait Posture"},{"issue":"10","key":"2025030510393343100_bib2","doi-asserted-by":"crossref","first-page":"1095","DOI":"10.1016\/0003-9993(93)90068-L","article-title":"An Analysis of Sit-to-Stand Movements","volume":"74","year":"1993","journal-title":"Arch.
