“…Obese boys also showed greater sway areas and variability in the medial/lateral direction when compared with non-obese prepubertal boys. 12 Altogether, these studies support the view that overweight can yield poorer balance. More recently, Bernard et al 13 reported similar results in obese teenagers but only when the postural control was stressed by adding a foam surface.…”

Objective: To investigate the effect of weight loss on balance control in obese and morbid obese men. Methods: In a longitudinal and clinical intervention study, postural stability was measured with a force platform before and after weight loss in men. Weight loss was obtained in obese men (mean body mass index (BMI) ¼ 33.0 kg/m 2 ) by hypocaloric diet until resistance and in morbid obese men (mean BMI ¼ 50.5 kg/m 2 ) by bariatric surgery. Morbid obese men were tested before surgery, and 3 and 12 months after surgery when they had lost 20 and nearly 50% of initial body weight, respectively. Normal weight individuals (mean BMI ¼ 22.7 kg/m 2 ) were tested twice within a 6-to 12-month period to serve as control. Body fatness and fat distribution measures, and posturographic parameters of the center of foot pressure (CP) along the antero-posterior and medio-lateral axes for conditions with and without vision were performed in all subjects. Results: Weight loss averaged 12.3 kg after dieting and 71.3 kg after surgery. Body weight remained unchanged in the control group. After weight loss, nearly all measures of postural stability were improved with and without vision (i.e., CP speed and range in antero-posterior and medio-lateral axes). A strong linear relationship was observed between weight loss and improvement in balance control measured from CP speed (adjusted R 2 ¼ 0.65, Po0.001). Conclusion: Weight loss improves balance control in obese men and the extent of the improvement is directly related to the amount of weight loss. This should decrease the habitual greater risk of falling observed in obese individuals.

“…Compared to lean individuals, obese persons walk slower with a greater stride width and spend a longer percentage of their gait cycle in dual stance. 9,[12][13][14] This has been associated with a less stable gait pattern. 15,16 Obese people also showed a less stable pattern for a sit-to-stand task.…”

Introduction: Obesity yields a decreased postural stability. The potentially negative impact of obesity on the control of upper limb movements, however, has not been documented. This study sought to examine if obesity imposes an additional balance control constraint limiting the speed and accuracy with which an upper limb goal-directed movement performed from an upright standing position can be executed. Method: Eight healthy lean subjects (body mass index (BMI) between 20.9 and 25.0 kg/m 2 ) and nine healthy obese subjects (BMI between 30.5 and 48.6 kg/m 2 ) pointed to a target located in front of them from an upright standing posture. The task was to aim at the target as fast and as precisely as possible after an auditory signal. The difficulty of the task was varied by using different target sizes (0.5, 1.0, 2.5 and 5.0 cm width). Hand movement time (MT) and velocity profiles were measured to quantify the aiming. Centre of pressure and segmental kinematics were analysed to document postural stability. Results: When aiming, the forward centre of pressure (CP) displacement was greater for the obese group than for the normal BMI group (4.6 and 1.9 cm, respectively). For the obese group, a decrease in the target size was associated with an increase in backward CP displacement and CP peak speed whereas for the normal BMI group backward CP displacements and CP peak speed were about the same across all target sizes. Obese participants aimed at the target moving their whole body forward whereas the normal BMI subjects predominantly made an elbow extension and shoulder flexion. For both groups, MT increased with a decreasing target size. Compare to the normal BMI group, this effect was exacerbated for the obese group. For the two smallest targets, movements were on average 115 and 145 ms slower for the obese than for the normal BMI group suggesting that obesity added a balance constraint and limited the speed with which an accurate movement could be done. Summary: Obesity, because of its effects on the control of balance, also imposes constraints on goal-directed movements. From a clinical perspective, obese individuals might be less efficient and more at risk of injuries than normal weight individuals in a large number of work tasks and daily activities requiring upper limb movements performed from an upright standing position.

“…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.
