Purpose:
: Evidence suggests a negative effect of obesity on musculoskeletal health in children. A pilot study was undertaken to investigate the presence of musculoskeletal impairments in children with obesity and to explore the relationships among body mass index, physical activity, and musculoskeletal measures.
Methods:
: Lower limb musculoskeletal health (pain, power, balance, flexibility, and range of motion), physical activity, and screen time were assessed using standardized methods.
Results:
: Seventeen children (mean age = 12.21 years) participated. Mean values for lower limb musculoskeletal measures are presented. Moderate negative correlations were found between body composition and range of motion, flexibility, and strength. Genu valgum deformity was moderately positively correlated to body mass index.
Conclusions:
: The results of this pilot study suggest that children who are obese may present with musculoskeletal impairments of the lower limb. Clinicians working with children who are obese should conduct a thorough musculoskeletal assessment and consider the presence of impairments when promoting physical activity.
