Pusher syndrome is a disorder of postural control observed in patients with right or left brain damage associated with hemiparesis. Those patients show a peculiar behavior of actively pushing away from the nonhemiparetic side and resisting against passive correction, with a tendency to fall toward the paralyzed side. Thus far this phenomenon has been(More)
Assessing interindividual variability of brain activation is of practical importance to the use of functional magnetic resonance imaging (fMRI) in the clinical context. The main objective of this study is to analyze the variability of the oculomotor system through horizontal optokinetic, pursuit and saccadic eye movement stimulations by means of fMRI. We(More)
We report a sequential neuroimaging study in a 48-years-old man with a history of chronic hypertension and lacunar strokes involving the ventral lateral posterior nucleus of the thalamus. The patient developed mild hemiparesis and severe contraversive pushing behavior after an acute hemorrhage affecting the right thalamus. Following standard motor(More)
UNLABELLED Subjective visual vertical (SVV) evaluates the individual's capacity to determine the vertical orientation. Using a neck brace (NB) allow volunteers' heads fixation to reduce cephalic tilt during the exam, preventing compensatory ocular torsion and erroneous influence on SVV result. OBJECTIVE To analyze the influence of somatosensory inputs(More)
UNLABELLED Early detection of postural disorders is essential for timely interventions in patients with imbalance. AIM A pilot study describing a new tool for evaluating static postural balance. STUDY DESIGN A cross-sectional study of a contemporary series. MATERIAL AND METHOD Twenty-five volunteers (15 women and 10 men) were evaluated. The mean age(More)
Pathologic tilt of subjective visual vertical (SVV) frequently has adverse functional consequences for patients with stroke and vestibular disorders. Repetitive transcranial magnetic stimulation (rTMS) of the supramarginal gyrus can produce a transitory tilt on SVV in healthy subjects. However, the effect of transcranial direct current stimulation (tDCS) on(More)
BACKGROUND The modified Rankin Scale (mRS) is a commonly used scale to assess the functional outcome after stroke. Several studies on mRS showed good reliability, feasibility, and interrater agreement of this scale using a face-to-face assessment. However, telephone assessment is a more time-efficient way to obtain an mRS grade than a face-to-face(More)
OBJECTIVE The aim of this study was to assess the subjective visual vertical in patients with bilateral vestibular dysfunction and to propose a new method to analyze subjective visual vertical data in these patients. METHODS Static subjective visual vertical tests were performed in 40 subjects split into two groups. Group A consisted of 20 healthy(More)
Evidence suggests that somatosensory electrical stimulation (SES) may decrease the degree of spasticity from neural drives, although there is no agreement between corticospinal modulation and the level of spasticity. Thus, stroke patients and healthy subjects were submitted to SES (3 Hz) for 30' on the impaired and dominant forearms, respectively. Motor(More)
