Resumo: | Research has shown that bimanual actions are demonstrative of the functional brain development; thus it is relevant to investigate how interlimb coordination develops in typically-developing infants, as well as in infants with impaired brain organization, such as in the presence of Down syndrome (DS). Objectives: The aims of this study were as follows: 1) to study the development of interlimb coordination in typically-developing infants (TD) and in infants with DS while reaching and grasping objects with different sizes; and 2) to investigate changes in the interlimb relations during the stages after reaching emergence. Methods: Reaching movements performed by 8 TD infants and 7 infants with DS were monthly recorded between the ages of 4 and 8 months. The frequency of categories used during movement initiation, object touching and grasping; the frequency of reaching and the contribution of each arm were calculated. The effects of object size and of the time after reaching onset were analyzed in intra- and inter-group comparisons. Results: TD infants were able to change the configurations used in the movement initiation, object touching and grasping; their interlimb coordination changed from synchronic reaches to asynchrony or unimanual trajectories, based on object properties. Infants with DS only changed their grasping configurations; the strategies they used were not optimally adjusted to object properties; difficulties to grasp the objects were also evident. Conclusions: With the experience in reaching, interlimb coordination in TD infants is increasingly modulated by object properties in an anticipatory way. Infants with DS seem to need a longer time to use sensory information and to modulate reaching and grasping configurations. |

OBJETIVO: Estudar o desenvolvimento da coordenação intermembros em LT e com SD ao alcançar e apreender objetos distintos e identificar se há mudanças nas relações intermembros nos períodos após a aquisição do alcance. MÉTODOS: Oito LT e sete lactentes com SD com idade de 4 a 8 meses foram posicionados em uma cadeira infantil e objetos grandes e pequenos foram apresentados por 1 minuto cada. Foi calculada a frequência das variáveis categoriais adotadas no início e trajetória, toque e apreensão do objeto. O efeito do tamanho dos objetos e do tempo após a aquisição do alcance foi analisado nas comparações intra e entre grupos. RESULTADOS: LT mudaram as configurações de início, toque e apreensão do objeto nos períodos após a aquisição do alcance, evoluindo de movimentos sincrônicos para trajetórias assincrônicas ou unimanuais, atendendo às propriedades dos objetos. Lactentes com SD mudaram apenas as configurações de apreensão, apresentando estratégias menos ajustadas aos objetos e dificuldades para apreender os mesmos. CONCLUSÃO: Ao longo da experiência de alcançar, a coordenação intermembros em LT é modificada e progressivamente modulada pelas propriedades dos objetos de maneira antecipatória. Lactentes com SD parecem necessitar de mais tempo para utilizar informações sensoriais e modificar configurações do alcance e apreensão.Financiadora de Estudos e Projetosapplication/pdfporUniversidade Federal de São CarlosPrograma de Pós-Graduação em Fisioterapia - PPGFtUFSCarBREducação especialDesenvolvimento motorAlcance manualDown, Síndrome dePreensãoCoordenação intermembrosapreensãoTamanho do objetoReachingInterlimb coordinationDown syndromeGraspingObject sizeCIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONALCoordenação intermembros no alcance de objetos de lactentes típicos e com síndrome de DownInterlimb coordination during reaching movements in typical infants and infants with Down syndromeinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL4366.pdfapplication/pdf1667152https://{{ getenv "DSPACE_HOST" "repositorio.ufscar.br" }}/bitstream/ufscar/5294/1/4366.pdfe2c5f2da90a5571724bcc0550299f17dMD51TEXT4366.pdf.txt4366.pdf.txtExtracted texttext/plain0https://{{ getenv "DSPACE_HOST" "repositorio.ufscar.br" }}/bitstream/ufscar/5294/2/4366.pdf.txtd41d8cd98f00b204e9800998ecf8427eMD52THUMBNAIL4366.pdf.jpg4366.pdf.jpgIM Thumbnailimage/jpeg6015https://{{ getenv "DSPACE_HOST" "repositorio.ufscar.br" }}/bitstream/ufscar/5294/3/4366.pdf.jpgadb3942b059cd9fa3b3f367b83badbe8MD53ufscar/52942019-09-11 04:16:50.321oai:repositorio.ufscar.br:ufscar/5294Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-05-25T12:49:48.766044Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
