Measurements were taken during a single follow\u2010up visit, which occurred between 1 and 7\u00a0years after the rupture. Tendon load was assessed using a shear wave tensiometer comprising a set of four accelerometers attached to the tendon. Stiffness, thickness, and cross\u2010sectional area (CSA) were also assessed using MyotonPRO and ultrasound imaging.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No significant differences in SWS were found between the affected AT and the unaffected side when analyzing the entire group (<jats:italic>p<\/jats:italic>\u00a0&gt;\u00a00.05). However, significant differences between sides were observed at 3.5 Nm and 7 Nm (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.001 and <jats:italic>p<\/jats:italic>\u00a0=\u00a00.020) for participants that experienced a lesion of the mid tendon. Higher plantar flexor strength was found for the unaffected side (320\u00a0\u00b1\u00a099.5 Nm) compared to the affected side (261\u00a0\u00b1\u00a080 Nm; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.001). Thickness and CSA in the proximal and distal part of the tendon were significantly higher in the affected tendon compared to the unaffected side (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>There is no difference in SWS values between the affected and the unaffected AT in the longer term after the rupture. However, differences in SWS were detected at specific contraction levels in participants with a mid\u2010tendon lesion. Moreover, tendon thickness and the cross\u2010sectional area, as well as plantar flexor strength, remain different between the affected and the unaffected AT.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jfa2.70047","type":"journal-article","created":{"date-parts":[[2025,4,28]],"date-time":"2025-04-28T06:41:12Z","timestamp":1745822472000},"source":"Crossref","is-referenced-by-count":0,"title":["Shear Wave Tensiometry in the Evaluation of Achilles Tendon Loading: A Cross\u2010Sectional Study on Conservatively Treated Tendons After Rupture"],"prefix":"10.1002","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8411-2012","authenticated-orcid":false,"given":"Alessandro","family":"Schneebeli","sequence":"first","affiliation":[{"name":"Centre of Precision Rehabilitation for Spinal Pain (CPR Spine) School of Sport, Exercise and Rehabilitation Sciences College of Life and Environmental Sciences University of Birmingham  Birmingham UK"},{"name":"Rehabilitation Research Laboratory 2rLab Department of Business Economics Health and Social Care University of Applied Sciences and Arts of Southern Switzerland  Manno Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8136-0977","authenticated-orcid":false,"given":"Giuseppe","family":"Filardo","sequence":"additional","affiliation":[{"name":"Service of Orthopaedics and Traumatology Department of Surgery EOC  Lugano Switzerland"},{"name":"Faculty of Biomedical Sciences Universit\u00e0 Della Svizzera Italiana  Lugano Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6153-0011","authenticated-orcid":false,"given":"Enrique","family":"Testa","sequence":"additional","affiliation":[{"name":"Faculty of Biomedical Sciences Universit\u00e0 Della Svizzera Italiana  Lugano Switzerland"},{"name":"Service of Orthopaedics and Traumatology Department of Surgery EOC  Bellinzona Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2637-2625","authenticated-orcid":false,"given":"Martin","family":"Riegger","sequence":"additional","affiliation":[{"name":"Service of Orthopaedics and Traumatology Department of Surgery EOC  Lugano Switzerland"},{"name":"Faculty of Biomedical Sciences Universit\u00e0 Della Svizzera Italiana  Lugano Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1689-6190","authenticated-orcid":false,"given":"Deborah","family":"Falla","sequence":"additional","affiliation":[{"name":"Centre of Precision Rehabilitation for Spinal Pain (CPR Spine) School of Sport, Exercise and Rehabilitation Sciences College of Life and Environmental Sciences University of Birmingham  Birmingham UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9550-5412","authenticated-orcid":false,"given":"Alessandro","family":"Sangiorgio","sequence":"additional","affiliation":[{"name":"Service of Orthopaedics and Traumatology Department of Surgery EOC  Lugano Switzerland"},{"name":"Clinics of Rehabilitation Ente Ospedaliero Cantonale (CREOC)  Novaggio\/Faido Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1632-6684","authenticated-orcid":false,"given":"Corrado","family":"Cescon","sequence":"additional","affiliation":[{"name":"Rehabilitation Research Laboratory 2rLab Department of Business Economics Health and Social Care University of Applied Sciences and Arts of Southern Switzerland  Manno Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9577-5567","authenticated-orcid":false,"given":"Emiliano","family":"Soldini","sequence":"additional","affiliation":[{"name":"Competence Centre for Healthcare Practices and Policies Department of Business Economics, Health, and Social Care University of Applied Sciences and Arts of Southern Switzerland  Manno Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8579-0686","authenticated-orcid":false,"given":"Marco","family":"Barbero","sequence":"additional","affiliation":[{"name":"Rehabilitation Research Laboratory 2rLab Department of Business Economics Health and Social Care University of Applied Sciences and Arts of Southern Switzerland  Manno Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,4,27]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546510376052"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546513503282"},{"issue":"1","key":"e_1_2_12_4_1","first-page":"91","article-title":"Nonoperative or Surgical Treatment of Acute Achilles\u2019 Tendon Rupture.
