Weight-bearing and walking stability stand as key performance indicators to quantify fracture restoration. Normally, progress in fracture rehabilitation is observed through clinical assessments and patients\u2019 responses, and modern research also presents instrumented gait analysis. There exists a gap to statistically compute the regaining in patients\u2019 weight-bearing ability and walking stability following fractures. This study introduces methods to advance the analysis of instrumented signals and evaluate walking stability in fracture-healing patients. The centre of pressure (CoP) signals were captured for four conditions: tibia\/fibula\/talus fracture near the ankle (AF), lower-leg shaft fracture (LF), calcaneus fractures (CF), and normal ankle (NA). The time derivative for CoP signals showed impulsive responses during the loading and unloading transitions which were then modelled and transformed to the frequency domain. The developed models were further analysed by applying Nyquist and Bode methods and margins of stability were calculated for the fractured and healthy subjects. Results showed a substantial decline (Kruskal-Wallis\u2019s test,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001) in the intralimb stability of all three fractures. Also, there was a strong interlimb dependency (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001) observed between fractured and intact limbs applying Spearman\u2019s correlation during double limb support periods. Overall, the calcaneus fracture (CF) exhibited minimum intralimb stability and increased interlimb dependency. These methods stand clinically important in monitoring patients\u2019 rehabilitation and in decision-making about alternative treatment plans.\n                  <\/jats:p>","DOI":"10.1177\/09544119251348490","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T05:07:22Z","timestamp":1751864842000},"page":"644-655","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Novel methods to quantify gait rehabilitation following ankle-foot fractures"],"prefix":"10.1177","volume":"239","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9832-6815","authenticated-orcid":false,"given":"Imran","family":"Mahmood","sequence":"first","affiliation":[{"name":"Mechanical, Mechatronics, and Manufacturing Engineering Department, Faisalabad Campus, UET Lahore, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anam","family":"Raza","sequence":"additional","affiliation":[{"name":"Department of Zoology, Government College University, Faisalabad, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tayyaba","family":"Sultana","sequence":"additional","affiliation":[{"name":"Department of Zoology, Government College University, Faisalabad, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abbas A","family":"Dehghani-Sanij","sequence":"additional","affiliation":[{"name":"Institute of Design, Robotics and Optimization, School of Mechanical Engineering, University of Leeds, Leeds, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,7,7]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S2666-7568(21)00172-0"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.medengphy.2021.10.010"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11517-022-02587-z"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41597-020-0481-z"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.humov.2019.102558"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.medengphy.2020.04.005"},{"key":"e_1_3_2_8_2","unstructured":"Physiopedia.
