Developmental changes in lower limb joint ranges of motion in Japanese children aged 6–15 years

Assessing lower limb ranges of motion (ROMs) is crucial for diagnosing and treating musculoskeletal and neurological disorders in children. Although prior studies examining decline in flexibility among school-age children suggest potential age-related changes in lower limb ROMs, this hypothesis remains unproven. Therefore, in this study, we aim to examine age-related differences in lower limb ROMs among school-age children.
