The Nature of Developmental Coordination Disorder: Inter- and Intragroup Differences

Abstract

The nature of developmental coordination disorder (DCD) in a selected group of Singaporean children (n = 69) aged 6-9 years was investigated by two methods: an intergroup comparison of children with DCD and matched controls (n = 69), and an intragroup study on the same children with DCD in the search for subtypes within this group. The results from the two approaches demonstrate that while the children with DCD are clearly different from the control subjects, the difficulties seen within the DCD group are not common to all the children. Four identifiable subtypes were found within the children with DCD. This more specific information gained about the difficulties children with DCD experience is not easily established from the intergroup analysis, suggesting that the design of future intervention studies should incorporate differences found in subtypes of children with DCD.

Developmental coordination disorder in children with attention‐deficit–hyperactivity disorder and physical therapy intervention

“…Indeed, individualizing therapy according to the child's needs and progress seems to be of utmost importance to ensure efficacy of physical therapy for these patients. 23,24 Furthermore, increasing the involvement of family members in the treatment course, while promoting a more active attitude towards the child's performance, appears to further enhance the chances for improving the patient's motor skills and self-esteem. 23,25 In our study, based on these principles, we attempted to cover both aspects to provide children with ADHD/DCD in group A with better tools to achieve higher MABC scores.…”

Identificação de sinais de Transtornos do Desenvolvimento da Coordenação em crianças de três a seis anos e possibilidades de atuação da Terapia Ocupacional

“…Embora a dificuldade motora seja aparente, alguns autores relatam que as características associadas ao TDC não atingem somente a maioria das habilidades motoras notáveis, mas apresentam associações com os aspectos emocionais e sociais (WRIGHT;SUGDEN, 1996).…”

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

“…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.…”

“…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".…”

“…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.…”
