Center of Pressure Speed Changes with tDCS Versus GVS in Patients with Lateropulsion after Stroke

We offer this letter to spark discussion about potential transcranial methods to augment rehabilitation to ameliorate lateropulsion after stroke. Patients with lateropulsion after stroke, also known as ‘pusher syndrome,’ actively push themselves to the weak side and resist passive correction of the posture to the vertical upright [1]. Various lesion sites along pathways which formulate subjective perceptions of verticality have been implicated in lateropulsion. Transcranial direct current stim ulation (tDCS) or galvanic vestibular stimulation (GVS) over parts of the impaired pathways may change seated center of pressure for patients with lateropulsion and provide insight into the nature of the lesioned pathway.
