Visually directed reaching of children with motor impairments / Agneta FORSSTROM in Developmental Medicine & Child Neurology, 24-5 (October 1982)
[article]
Titre : Visually directed reaching of children with motor impairments Type de document : Texte imprimé et/ou numérique Auteurs : Agneta FORSSTROM, Auteur ; Claes VON HOFSTEN, Auteur Année de publication : 1982 Article en page(s) : p.653-661 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Impaired postural fixation affects the efficiency and flexibility of impending movements. 38 children aged between four and 11 years with abnormal postural fixation associated with slight neurological disturbances were studied, together with a matched control group, when reaching for a moving object. 298 reaches from each group were analysed by a technique which took into account the three-dimensional properties of the reaches. Acceleration profiles were analysed and used to divide reaches into movement elements. The aiming of those elements were calculated and compared with an optimal value. The test indicated the following: the relative lengths of approach paths was greater for the children in the clinical group than for the controls; the neurologically impaired children were less apt than the controls to increase the efficiency of their reaching patterns; but they took their less efficient motor performance into account when planning the reach and aimed further ahead of the target than the controls.
