The procedure allows the selection of the elements of the foot and the materials used for the design. The procedure is based on the optimization where the cost function is the minimization of the difference between the knee joint torques of healthy walking and the walking with the transfemural prosthesis. We present a simulation environment that allows the user to interactively vary the foot geometry and track the changes in the knee torque that arise from these adjustments. The software allows the estimation of the optimal prosthetic foot elasticity and geometry. We show that altering model attributes such as the length of the elastic foot segment or its elasticity leads to significant changes in the estimated knee torque required for a given trajectory.<\/jats:p>","DOI":"10.1155\/2012\/421796","type":"journal-article","created":{"date-parts":[[2012,3,29]],"date-time":"2012-03-29T21:03:54Z","timestamp":1333055034000},"page":"1-8","source":"Crossref","is-referenced-by-count":4,"title":["Software Tool for the Prosthetic Foot Modeling and Stiffness Optimization"],"prefix":"10.1155","volume":"2012","author":[{"given":"Matija","family":"\u0160trbac","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dejan B.","family":"Popovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Aalborg University, Center for Sensory Motor Interaction, 9200 Aalborg, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","first-page":"142","volume":"2009","year":"2009","journal-title":"Indian Journal of Biomechanics"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2008.2010470"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/86.750554"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1007\/BF02534094"},{"issue":"12","key":"10","doi-asserted-by":"crossref","first-page":"1874","DOI":"10.1093\/ptj\/68.12.1874","volume":"68","year":"1988","journal-title":"Physical Therapy"},{"issue":"3","key":"11","doi-asserted-by":"crossref","first-page":"117","DOI":"10.3109\/03093649009080337","volume":"14","year":"1990","journal-title":"Prosthetics and Orthotics International"},{"issue":"1","key":"12","doi-asserted-by":"crossref","first-page":"37","DOI":"10.3109\/03093649509078230","volume":"19","year":"1995","journal-title":"Prosthetics and Orthotics International"},{"issue":"5","key":"13","doi-asserted-by":"crossref","first-page":"344","DOI":"10.1093\/ptj\/72.5.344","volume":"72","year":"1992","journal-title":"Physical Therapy"},{"issue":"3","key":"14","doi-asserted-by":"crossref","first-page":"174","DOI":"10.3109\/03093649209164337","volume":"16","year":"1992","journal-title":"Prosthetics and Orthotics International"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2003.823266"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/S0268-0033(97)00041-7"},{"key":"17","year":"1999"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/86.536776"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1016\/j.humov.2004.08.023"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1682\/JRRD.2010.09.0167"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1682\/JRRD.2008.02.0025"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/421796.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/421796.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/421796.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,7,5]],"date-time":"2020-07-05T02:02:27Z","timestamp":1593914547000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2012\/421796\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":16,"alternative-id":["421796","421796"],"URL":"https:\/\/doi.org\/10.1155\/2012\/421796","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"value":"1748-670X","type":"print"},{"value":"1748-6718","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
