Nevertheless, the lack of studies focusing on standing para XC skiing highlights the need to provide a comprehensive description of this sport, investigating how different prosthetic devices may influence the athletic outcome. In this exploratory case study, the biomechanics of an elite standing para-athlete, with a right-sided transfemoral amputation, was investigated. Tests were performed during diagonal XC skiing on a treadmill, at different speeds and inclinations. Specifically, two different prosthetic feet were compared: the athlete used an Ottobock Genium X3 prosthetic knee with either the Ottobock Taleo or the Ottobock Evanto prosthetic foot. Inertial Measurement Units (IMUs) were employed to estimate joint angles and detect pole hits and lifts. Additionally, data were collected using embedded sensors in the knee prosthesis. Diagonal stride spatiotemporal parameters were further calculated. Results revealed that the Evanto foot significantly increased swing phase duration and hip range of motion, while generating higher knee torque, ankle torque, and axial loading compared to the Taleo foot. This research represents the first application of the employed testing methodology to para standing XC skiing, and it therefore provides a framework for future studies on this discipline.<\/jats:p>","DOI":"10.3390\/s26010149","type":"journal-article","created":{"date-parts":[[2025,12,25]],"date-time":"2025-12-25T23:52:27Z","timestamp":1766706747000},"page":"149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Biomechanical Analysis of an Elite Para Standing Cross-Country Skier Using Lower Limb Prostheses: A Case Study"],"prefix":"10.3390","volume":"26","author":[{"given":"Cristina","family":"De Vito","sequence":"first","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Politecnico di Torino, 10129 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian","family":"Pasluosta","sequence":"additional","affiliation":[{"name":"Laboratory for Biomedical Microtechnology, Department of Microsystems Engineering (IMTEK), Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"},{"name":"BrainLinks-BrainTools Center, Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7169-4300","authenticated-orcid":false,"given":"Patrick","family":"Ofner","sequence":"additional","affiliation":[{"name":"Laboratory for Biomedical Microtechnology, Department of Microsystems Engineering (IMTEK), Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"},{"name":"Institute of Sport and Sport Science, Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0743-9972","authenticated-orcid":false,"given":"Leonie","family":"Hirsch","sequence":"additional","affiliation":[{"name":"Institute of Sport and Sport Science, Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2814-5351","authenticated-orcid":false,"given":"Natalie","family":"Mrachacz-Kersting","sequence":"additional","affiliation":[{"name":"BrainLinks-BrainTools Center, Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"},{"name":"Institute of Sport and Sport Science, Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uwe","family":"Kersting","sequence":"additional","affiliation":[{"name":"Institute of Biomechanics and Orthopaedics, German Sport University Cologne, 50933 Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7349-4254","authenticated-orcid":false,"given":"Thomas","family":"Stieglitz","sequence":"additional","affiliation":[{"name":"Laboratory for Biomedical Microtechnology, Department of Microsystems Engineering (IMTEK), Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"},{"name":"BrainLinks-BrainTools Center, Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"},{"name":"Institute of Sport and Sport Science, Albert-Ludwigs-Universit\u00e4t Freiburg, 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walter","family":"Rapp","sequence":"additional","affiliation":[{"name":"Olympic Training Center, 79117 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3921-3022","authenticated-orcid":false,"given":"Laura","family":"Gastaldi","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Politecnico di Torino, 10129 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Vanlandewijck, Y.C., and Thompson, W.R.
