Controle de movimentos voluntários no membro superior não plégico de portadores de paralisia cerebral hemiplégica espástica

Abstract: Objetivo: Analisar os movimentos de flexão do ombro e do cotovelo do hemicorpo não plégico de portadores de paralisia cerebral (PC) hemiplégica espástica e do hemicorpo mais utilizado de indivíduos sem comprometimento motor e/ou neurológico (normais). Métodos: Seis portadores de PC (18,2 ± 3,7 anos) e seis indivíduos normais (18,5 ± 3,3 anos) participaram deste estudo. Marcadores ativos foram afixados nos centros articulares do ombro, cotovelo e punho para aquisição de dados cinemáticos e eletrodos de superfíc… Show more

“…Since accuracy requirements call upon the capability to stabilize the end-effector in the vicinity of a to-be-reached target (Mottet and Bootsma 1999;Fernandez and Bootsma 2004), the neuromuscular mechanisms underlying this particular capability would seem to be affected by CP. We suggest that fine-tuning of muscle activation levels is likely to be involved in this stabilization capability, since reduced contractile potential of more distal muscles has been reported as a primary deficit in individuals with CP ( Barela and Almeida 2006;Mackey et al 2006;Jaspers et al 2011;Klingels et al 2012). Such reduced capability of children with CP to fine-tune muscular activation according to task demands has already been noted in the context of postural tasks (Hadders-Algra et al 1999).…”
