Lateropulsion with active pushing in stroke patients: its link with lesion location and the perception of verticality. A systematic review.

A complex brain network, rather than only one brain region, seems responsible for body control with respect to gravity. A disruption within this network might lead to a bias in the construction of a correct internal reference frame, crucial for perceiving verticality. There was an association of LwP with verticality misperception in all three modalities.
