While fear of falling (FoF) and a history of falls (HoF) increase fall risk in older adults, their relationship with intra- and intersegmental coordination during gait remains understudied. This cross-sectional observational study involved 60 participants aged 60 and older. The three-dimensional range of motion of lower limb joints during gait was assessed using an optoelectronic system. Intra- and intersegmental coordination were evaluated via the Continuous Relative Phase (CRP) variable, including its mean, standard deviation, and coefficient of variation. The results showed that the HoF and FoF groups had higher mean CRP values in the left hip-knee (HOF, p = 0.004) and hip-ankle (FOF, p = 0.030) in the sagittal plane, as well as higher standard deviation values in the left knee-ankle (HOF, p = 0.006) and right hip-ankle (HOF, p = 0.004). Inter-segmental coordination differences were also observed, with higher mean CRP values between the knee joints in the sagittal plane (HOF, p = 0.046) and lower mean and standard deviation values between the ankle joints (FOF, p = 0.048 and p = 0.038, respectively). This study concludes that fear of falling and history of falling are significantly associated with altered intra- and intersegmental coordination in older adults, which may contribute to fall risk. Understanding these altered coordination patterns is crucial, as it underscores the therapeutic significance of targeting these changes, which could lead to interventions aimed at improving gait stability and reducing fall risk in elderly individuals.<\/jats:p>","DOI":"10.3390\/sym17060818","type":"journal-article","created":{"date-parts":[[2025,5,25]],"date-time":"2025-05-25T20:39:36Z","timestamp":1748205576000},"page":"818","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Association Between Gait Lower Limb Intra and Interlimb Coordination and Fear of Falling and Falling History in Older Adults"],"prefix":"10.3390","volume":"17","author":[{"given":"M\u00e1rcia","family":"Castro","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":[[2025,5,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1007\/s00221-008-1464-z","article-title":"Intersegmental coordination while walking up inclined surfaces: Age and ramp angle effects","volume":"189","author":"Noble","year":"2008","journal-title":"Exp.
