This method is valid not only on level ground but also on incline and decline conditions. The method leverages the \u201ccrackle\u201d function, the third derivative of the sacral resultant acceleration, to identify right and left gait events. This approach is particularly effective in capturing the initial peak in acceleration data during foot impact with the ground, often overlooked by other methods. The study aimed to demonstrate the method\u2019s accuracy in identifying the right- and left-side impacts during level ground, incline, and decline runs across a range of speeds. Additionally, the algorithm was applied in outdoor running scenarios, where it performed very well, further validating its robustness and reliability. The results are compared with other existing methods to highlight the effectiveness of this approach.<\/jats:p>","DOI":"10.1017\/wtc.2025.4","type":"journal-article","created":{"date-parts":[[2025,2,28]],"date-time":"2025-02-28T08:53:09Z","timestamp":1740732789000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":3,"title":["Identifying right and left impact using the derivative of linear resultant acceleration from a single sacrum-mounted IMU"],"prefix":"10.1017","volume":"6","author":[{"given":"Aida","family":"Chebbi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel M.","family":"Robinson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seth R.","family":"Donahue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5024-700X","authenticated-orcid":false,"given":"Michael E.","family":"Hahn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"S2631717625000040_r3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2011.12.020"},{"key":"S2631717625000040_r1","doi-asserted-by":"publisher","DOI":"10.1016\/S0765-1597(02)00122-3"},{"key":"S2631717625000040_r6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsams.2009.01.005"},{"key":"S2631717625000040_r10","doi-asserted-by":"publisher","DOI":"10.1007\/s12283-010-0043-2"},{"key":"S2631717625000040_r11","first-page":"1","article-title":"Intelligent wearable systems: Opportunities and challenges in health and sports","volume":"56","author":"Yang","year":"2024","journal-title":"ACM Computing Surveys"},{"key":"S2631717625000040_r8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2021.110419"},{"key":"S2631717625000040_r9","first-page":"10","volume-title":"Proceedings","volume":"49","author":"Wada","year":"2020"},{"key":"S2631717625000040_r12","doi-asserted-by":"publisher","DOI":"10.1186\/s40798-022-00477-0"},{"key":"S2631717625000040_r4","unstructured":"Chebbi, A. , Donahue, S. , Robinson, R. , & Hahn, M.
