“…This finding concurs with McMillan et al [7] who reported greater peak calcaneus plantarflexion during the early part of stance phase in obese compared to non-obese children. Greater plantarflexion of the calcaneus segment may represent a horizontal position of the calcaneal bone and a vertically orientated talus.…”

“…Childhood obesity has been reported to impact on the functional characteristics of the lower limb, potentially predisposing children to pain and discomfort during gait and musculoskeletal comorbidities [6]. Recent studies have reported reduced hip and knee flexion during gait and greater valgus positioning of the knee [7]. These findings support the view that obesity predisposes joint dysfunction and underpins a theoretical association with musculoskeletal pathology.…”

PLEASE SCROLL DOWN FOR TEXT. 1The impact of body fat on three dimensional motion of the paediatric foot during walking AbstractChildhood obesity is commonly associated with a pes planus foot type and altered lower limb joint function during walking. However, limited information has been reported on dynamic intersegment foot motion with the level of obesity in children. The aim of this study was to explore the relationships between intersegment foot motion during gait and body fat in boys age 7 to 11 years.Fat mass was measured in fifty-five boys using air displacement plethysmography. Threedimensional gait analysis was conducted on the right foot of each participant using the 3DFoot model to capture angular motion of the shank, calcaneus, midfoot and metatarsals. Two multivariate statistical techniques were employed; principle component analysis reduced the multidimensional nature of gait analysis, and multiple linear regression analysis accounted for potential confounding factors.Higher fat mass predicted greater plantarflexion of the calcaneus during the first half and end of stance phase and at the end of swing phase. Greater abduction of the calcaneus throughout stance and swing was predicted by greater fat mass. At the midfoot, higher fat mass predicted greater dorsiflexion and eversion throughout the gait cycle.The findings present novel information on the relationships between intersegment angular motion of the foot and body fat in young boys. The data indicates a more pronated foot type in boys with greater body fat. These findings have clinical implications for pes planus and a predisposition for pain and discomfort during weight bearing activities potentially reducing motivation in obese children to be physically active.

“…This finding indicates that factors beyond BMI may be associated with reports of LE pain in obese children. Lower extremity malalignment is frequently present in obese children [28][29][30]52] and is associated with pain in other populations [45,47,48,64]. Further investigation into factors such as LE alignment that may differ between obese children with pain and those without pain is warranted.…”

“…Musculoskeletal comorbidities have become a recent focus of research in obese children. Obese children report more frequent and severe joint pain [13,51,53] and lower extremity malalignment is more prevalent in overweight and obese children [28][29][30]52]. Like with obese adults, obese children report lower function and healthrelated quality of life compared with their healthy peers [38,41,53,63], but less is known about factors in obese children that may contribute to poor function and quality of life.…”

Background Childhood obesity is associated with reduced quality of life, physical fitness, and a higher prevalence of lower extremity (LE) pain; however, it is unclear whether and how these factors are related. Questions/purposes For this study we asked if obese children with LE pain (LE+) had higher BMI-Z scores, lower physical function and psychosocial health, and lower physical fitness compared with obese children without LE pain (LEÀ). We determined the association of BMI-Z score with physical function, psychosocial health, or physical fitness in obese children.

Bone functional adaptation is routinely invoked to interpret skeletal morphology despite ongoing debate regarding the limits of the bone response to mechanical stimuli. The wide variation in human body mass presents an opportunity to explore the relationship between mechanical load and skeletal response in weight‐bearing elements. Here, we examine variation in femoral macroscopic morphology as a function of body mass index (BMI), which is used as a metric of load history. A sample of 80 femora (40 female; 40 male) from recent modern humans was selected from the Texas State University Donated Skeletal Collection. Femora were imaged using x‐ray computed tomography (voxel size ~0.5 mm), and segmented to produce surface models. Landmark‐based geometric morphometric analyses based on the Coherent Point Drift algorithm were conducted to quantify shape. Principal components analyses were used to summarize shape variation, and component scores were regressed on BMI. Within the male sample, increased BMI was associated with a mediolaterally expanded femoral shaft, as well as increased neck‐shaft angle and decreased femoral neck anteversion angle. No statistically significant relationships between shape and BMI were found in the female sample. While mechanical stimulus has traditionally been applied to changes in long bong diaphyseal shape it appears that bone functional adaptation may also result in fundamental changes in the shape of skeletal elements.
