The present study analyzed the dynamic balance of teenagers with Down syndrome (DS) and teenagers with typical development (TD). Fourteen 14 teenagers with DS and 22 teenagers with typical development (TD) performed the task of trying to keep their balance on a unstable platform. Balance was analyzed in conditions with and without vision, in the bipodal basis of support with the parallels feet and semi-tandem. Both groups showed a worse performance in the conditions with no vision. However, the teenagers with DS showed greater instability in the dynamic balance in comparison to the teenagers with TD for both, vision and non-vision conditions. Such results were explained by the characteristics normally verified in people with DS, such as: muscular hypotonic, ligamentous laxity, and the difficulty in the action-perception integration.
