Purpose: We aim to evaluate the association between HoF and FoF on spatiotemporal and lower-limb kinematic parameters in older adults during stair descents and gait transitions. Methods: Sixty older adults (&gt;60 years) were evaluated through an optoelectrical motion capture system during stair descents and gait transitions, using the mean value of the task velocity and time; single- and double-support time; peak downward center of mass (CoM) velocity; hip, knee, and ankle positions of ipsi and the contralateral limb; and foot clearance and foot placement, assessed through multivariate analysis of variance. Results: FOF exhibited longer time to complete (p = 0.009) and double-support (p = 0.047) and single-support (p = 0.009) times and a reduced peak downward CoM velocity (p = 0.043). In the gait transition cycle, HOF exhibited reduced ipsi ankle angles at toe-off (p = 0.015), and FOF presented reduced ipsi ankle angles at heel-strike (p = 0.041) and toe-off (p = 0.026) and reduced contralateral ankle angles at toe-off (p = 0.022). Conclusion: Older adults with HoF and FoF exhibit biomechanical changes during stair descents and gait transitions, in line with the use of more conservative strategies to avoid falling.<\/jats:p>","DOI":"10.3390\/app15126689","type":"journal-article","created":{"date-parts":[[2025,6,16]],"date-time":"2025-06-16T10:47:22Z","timestamp":1750070842000},"page":"6689","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Association Between the History of Fall and the Fear of Falling on Stair Descent and Gait Transition Spatiotemporal Parameters and Lower-Limb Kinematics in Older Adults"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7294-9696","authenticated-orcid":false,"given":"Ivone","family":"Teles","sequence":"first","affiliation":[{"name":"CIR, E2S, Polytechnic of Porto, Rua Dr. Ant\u00f3nio Bernardino de Almeida, 4200-072 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0123-4960","authenticated-orcid":false,"given":"Juliana","family":"Moreira","sequence":"additional","affiliation":[{"name":"CIR, E2S, Polytechnic of Porto, Rua Dr. Ant\u00f3nio Bernardino de Almeida, 4200-072 Porto, Portugal"},{"name":"Research Center in Physical Activity, Health and Leisure, Faculty of Sports, University of Porto, 4200-450 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9528-1463","authenticated-orcid":false,"given":"Andreia","family":"Sousa","sequence":"additional","affiliation":[{"name":"CIR, E2S, Polytechnic of Porto, Rua Dr. Ant\u00f3nio Bernardino de Almeida, 4200-072 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,14]]},"reference":[{"key":"ref_1","unstructured":"United Nations (2020, December 14).
