Age-related changes in spatiotemporal characteristics of gait accompany ongoing lower limb linear growth in late childhood and early adolescence

Abstract: Walking gait is generally held to reach maturity, including walking at adult-like velocities, by 7–8 years of age. Lower limb length, however, is a major determinant of gait, and continues to increase until 13–15 years of age. This study used a sample from the Fels Longitudinal Study (ages 8–30 years) to test the hypothesis that walking with adult-like velocity on immature lower limbs results in the retention of immature gait characteristics during late childhood and early adolescence. There was no relationshi… Show more

“…Again, comparing this sample's earliest and latest age at menarche quartiles helps illustrate this point. Girls in the earliest quartile had an average age at measurement of 16.2 years, but compared with our previous study's results [45], their average base of support was 2.62, typical of females aged 11.2 years in the Fels sample. In contrast, the latest quartile was measured at an average age of 16.4 years and had mean base of support of 3.28, narrower than expected for the typical postpubescent female.…”

“…Step width from walking trials was used to calculate base of support as (bicristal breadth/step width). To further quantify maturity of base of support, we also calculated age‐specific residuals from our previously published equations [45]. Dynamic knee frontal plane angle and moment at foot‐strike, as well as peak abduction angle and moment during stance phase, were derived from walking trials.…”

“…Results from previous studies in other populations may not be transferable to this population, because besides low physical fitness levels (Lahtinen et al 2007;Hilgenkamp et al 2010), adults with ID also have lifelong impairments in cognition and motor development/control (Enkelaar et al 2012;Almuhtaseb et al 2014; American Association on Intellectual and Developmental Disabilities 2018), which influence gait and thereby may alter the association between fitness and gait. In the general, population gait continues to mature until age 13-15 years (Froehle et al 2013). With increasing age, cognition and physical fitness start to decline, which both impact gait.…”
