Does subtype of developmental coordination disorder count: Is there a differential effect on outcome following intervention?

Hierarchical Agglomerative Cluster Analysis as a Trial Method Revealing Developmental Coordination Disorder (DCD) Subtypes

“…Longitudinal studies have highlighted associated problems, such as learning, behaviour, social and emotional adjustment, that children with coordination deficits are made up of distinctive subtypes either in type (or quality) of impairment; severity of coordination deficit; aetiology/history, and/or overlap with other conditions, and that these subgroups may require different intervention strategies [2]. The Green et al study highlighted the complexity of coordination disorders and considered whether there were substantive subtypes of coordination impairment that warrant differential interventions.…”

“…The balance was one of the few variables measured consistently across all relevant studies. Also, despite the differences in these four research trials [1][2][3][4][5] a common subgroup highlighted, which characterized by generalized problems in all examining domains. In Hoare [3] this subgroup was characterized by "generalized perceptual-motor dysfunction".…”

“…In other similar studies cluster analysis administered exclusively on DCD population [2][3][4][5]9]. In our study all participants, with and without DCD (N=108), were included in cluster analysis.…”

“…Children with DCD have been classified into distinguishable 'subtypes' mainly based on perceptual-motor, fine and gross motor skills [1][2][3][4][5] Wright & Sugden 1996b). These detailed studies describe in detail subgroups of DCD using the methods of cluster analysis.…”

“…Green, Champers & Sugden [2] used similar statistical procedures to those of Hoare and Macnab et al [3,4] for their subtyping study. The combined group of children with and without co-morbidity (N=90) showed five (5) clusters: cluster 1.…”
