The relationship between a child's postural stability and manual dexterity.

摘要: The neural systems responsible for postural control are separate from the substrates that underpin of hand. Nonetheless, and eye-hand coordination linked functionally. For example, a stable platform is required precise manual tasks (e.g. handwriting) thus such skills often cannot develop until child able to sit or stand upright. This raises question strength empirical relationship between measures stability motor control. We recorded objective computerised in stance sitting sample school children (n = 278) aged 3–11 years order explore extent which skill could be predicted by stability. A strong correlation was found across whole taken on different days. Following correction age, significant but modest found. Regression analysis with age revealed accounted 1 10 % variance performance, dependent specific task. These data reflect an interdependent functional development. Nevertheless, relatively small proportion explained consistent anatomically distinct architecture exists ‘gross’ ‘fine’ justify approach batteries provide assessments dexterity have implications therapeutic intervention developmental disorders.
