Brief Summary
Little is known about the time course of verticality perception after stroke. This study aims to assess:
- The time course of verticality perception (Subjective Visual, Haptic and Postural Vertical; resp., SVV, SHV, SPV);
- The longitudinal interaction of the recovery of spatial disorders (e.g., different types of neglect, lateropulsion) with verticality perception;
- The longitudinal interaction of motor function and outcomes (such as paresis, sitting balance and standing balance) and verticality perception. The participants will be repetitively assessed during the subacute phase post-stroke, to evaluate the time course of:
- The SVV, SHV and SPV;
- Spatial disorders (visuospatial and personal neglect, lateropulsion)
- Motor function (lower limb strength, sitting and standing balance, functionality in ADL, trunk performance)
