Ten individuals of both genders with diagnosis of spastic cerebral palsy, who had some control to voluntarily move the body and the upper limbs, participated in this study. Quantification of data was carried out in two experimental situations: (1) execution of a task of fitting with upper limbs, and with the individual placed on an adapted canvas seat; (2) execution of a task of fitting with the participant positioned on an adapted wooden seat. Data obtained were submitted to a non-parametric and descriptive statistical analysis using the Wilcoxon test. Results indicated that the use of canvas seat increased the contact area and decreased the pressure peak and the medio-lateral displacement of centre pressure on the seated posture. © 2011 Informa UK, Ltd.331-337engcerebral palsyPosturepressure distributionadolescentadultanthropometrybiomechanicsbody posturechildcomparative studyfemalehumanmaleman machine interactionnonparametric testphysiologypressuretask performancewheelchairAdolescentAnthropometryBiomechanicsCerebral PalsyChildFemaleHumansMaleMan-Machine SystemsPressureStatistics, NonparametricTask Performance and AnalysisWheelchairsYoung AdultArtigo10.3109/17483107.2010.529632Acesso restrito2-s2.0-799558671465197619968036480
