RESUMO

The analysis of sensorimotor integration in children with hemiparesis is necessary for choosing of efficient therapeutic strategies to functionality recovery. The objectives of this study were: i) to compare three instruments of tactile sensibility assessment; ii) to describe the alterations of tactile sensibility in children with hemiparesis. The Study Group (SG) had 11 boys and girls with hemiparesis, Gross Motor Function Classification System (GMFCS) = 1 or 2 (age = 9,1 years + 2,1) and the Control Group (CG) had 24 children without motor or sensorial alterations (age = 8,8 years + 1,4). The comparison of tactile sensibility was done with the Nottingham Sensory Assessment of (NSA), the two-point discrimination test (2PD) and the six-object stereognosis test. The results were submitted to ANOVA and Duncan´s test to compare the parametric variables and the Mann-Whitney U, and the Wilcoxon matched pairs were used for the non-parametric variables. = 0,05 was considered significant difference and 0,05 <<0,10 was considered marginally significant. The NSA showed a reduction on tactile sensibility in SG in the hemiparetic side (p<0,01) and in the non-affected side (p<0,01); and a decrease in spatial resolution only in the hemiparetic side. The 2PD was capable of detecting the impairment of spatial resolution in the palm of both hands of the children with hemiparesis (p<0,01). Although the precision on identifying objects is intact in children with hemiparesis, they took more time to complete the stereognosis test with the affected hand when compared with their non-affected hand (p<0,01) and when compared with the CG (p=0,03). In spite of the fact that the NSA had indicated tactile alteration in both sides of children with hemiparesis, the 2PD was more sensitive to detect problems of the spatial resolution of tactile information. The perception assessed by six-object stereognosis test was preserved in children with hemiparesis, although they had taken more time to finish the task with the affected hand. This result can be related to motor problems
