The Nature and Control of Postural Adaptations of Boys with and without Developmental Coordination Disorder
Przysucha, Eryk P.; Taylor, M. Jane; Weber, Douglas
Adapted Physical Activity Quarterly, v25 n1 p1-16 Jan 2008
This study compared the nature of postural adaptations and control tendencies, between 7 (n = 9) and 11-year-old boys (n = 10) with Developmental Coordination Disorder (DCD) and age-matched, younger (n = 10) and older (n = 9) peers in a leaning task. Examination of anterior-posterior, medio-lateral, maximum and mean area of sway, and path length revealed one significant interaction as older, unaffected boys swayed more than all other groups (p less than 0.01). As a group, boys with DCD displayed smaller anterior-posterior (p less than 0.01) and area of sway (p less than 0.01). Analysis of relative time spent in the corrective phase (p less than 0.002) revealed that boys with DCD spent 54% under feedback control while boys without DCD spent 78%. This was attributed to reduced proprioceptive sensitivity, as confirmed by significant differences between the groups (p less than 0.009) in spectral analysis of peak frequency of sway. (Contains 1 table and 2 figures.)
