Intenção motora: um estudo experimental sobre a representação do corpo em crianças com paralisia cerebral do tipo hemiparético

Abstract

In the paradigm of rubber hand illusion of ownership of that member can be transferred to a rubber hand after visual stimulation, tactile and proprioceptive synchronously. In experiment 1 was investigated the presence of the effects of the illusion of rubber hand in typicallydeveloping children and children with hemiparetic cerebral palsy. Thus, the contribution of the paradigm rubber hand illusion was found to investigate the representation of the body, since the illusion to occur description of the structural body must overlap the body image. Inexperiment 2 was verified the perception of the child's movement from situations that cause the illusion of rubber hand. Investigated thus the intention of the motion and the perception of sensory feedback. To investigate the presence of the effect of the rubber hand in typicallydeveloping children and children with hemiplegia, a repeated measures ANOVA was performed including the factors hemiplegia (hemiplegic right, left hemiplegic and typically developing children) and conditions (synchronous and asynchronous ). In all models the child's age was included as a covariate. Post-hoc analyzes were made by ANOVA withcorrection for multiple comparisons or t tests. The typically developing children showed the effects of the rubber hand illusion and the integrity of the structural representation and children with cerebral palsy showed weak effects of the rubber hand illusion and therefore structural deficit in the body description. The group of children with left cerebral palsy got abetter performance when compared to children with cerebral palsy right. Regarding the experiment 2 both typically developing children, as children with cerebral palsy were able to produce the perception of sensory feedback in the realization of the upper limb movement.
