UNLABELLED
Pusher syndrome is an interesting disorder of balance in patients with encephalic lesions characterized by the peculiar behavior of actively pushing away from the non-hemiparetic side and resisting against passive correction, with a tendency to fall toward the paralyzed side. The role of vestibular system on the pushing behavior is not clear.
AIM
To evaluate horizontal semicircular canal function in patients with Pusher syndrome, using caloric and rotation tests.
STUDY DESIGN
Observational prospective.
MATERIAL AND METHOD
We evaluated 9 inpatients with stroke and Pusher syndrome at the neurological unit of HCFMRP-USP. We applied neurological and neuropsychological exams, NIHSS, Scale for contraversive pushing (SCP), caloric and rotation tests.
RESULTS
We evaluated 9 patients (5 men) with mean age of 71.8 +/- 5.9 and mean NIHSS of 18.33. Three patients presented contralateral directional preponderance on caloric test and we found four patients with directional preponderance on analysis of the slow phase velocity of rotation test response.
CONCLUSION
Our findings indicate that a dysfunction of semicircular canals does not seem to be relevant for the clinical manifestations of the Pusher syndrome.
未标注
推挤综合征是一种发生于脑部病变患者的有趣的平衡障碍，其特征为具有主动向非偏瘫侧推开并抵抗被动纠正的特殊行为，且有向瘫痪侧跌倒的倾向。前庭系统在推挤行为中的作用尚不清楚。
目的
使用冷热试验和旋转试验评估推挤综合征患者的水平半规管功能。
研究设计
前瞻性观察研究。
材料与方法
我们在圣保罗大学医学院里贝朗普雷图医院神经科评估了9例患有中风和推挤综合征的住院患者。我们进行了神经学和神经心理学检查、美国国立卫生研究院卒中量表（NIHSS）、对抗性推挤量表（SCP）、冷热试验和旋转试验。
结果
我们评估了9例患者（5例男性），平均年龄为71.8±5.9岁，平均NIHSS为18.33。3例患者在冷热试验中出现对侧方向优势，在旋转试验反应慢相速度分析中我们发现4例患者存在方向优势。
结论
我们的研究结果表明，半规管功能障碍似乎与推挤综合征的临床表现无关。
