RESUMO

The Non-Alignment Syndrome (NAS) or "Pusher Syndrome" is a disorder in which hemiparetic/hemiplegic stroke patients bring their weight to their compromised hemibody, in all positions, resisting any attempt to passive posture realignment, pushing itself with the non affected limbs. This change results in loss of balance, increasing the risk of falls in these individuals. The most likely cause for this behavior is stroke, but can also occur after other types of brain injury, as traumas or tumors. Thus, studies about the anatomical origin of this dysfunction are fundamental to the health services that serve patients with stroke, providing a possible involvement of the syndrome, depending on the brain affected area, identifying earlier this symptom and outlining a more appropriate treatment for them. Therefore, this research aims to evaluate the correlation between NAS and specific brain lesions in patients with stroke. We evaluated 44 stroke patients at the Hospital da RestauraÃÃo (HR) in Recife-PE, by applying the Scale for Contraversive Pusher (SCP), Barthel Index, National Institute of Health Stroke Scale (NIHSS), as well as analysis of their image exams to identify and measure the injured brain areas. There was a correlation between the hemorrhagic right thalamus lesions and NAS among the studied patients, regardless of gender, age or lesion size. The behavior prevalence in the sample was about 20.45%, while those presented lower rates in both the NIHSS and the Barthel. It was verified in the end of this study that the thalamus was the structure most related to the occurrence of the NAS and that these individuals are presented with more severe hemiparesis and more dependent on the achievement of their functional activities
