Thalamic astasia (TA) is a condition characterized by difficulty maintaining an upright posture due to a unilateral lesion in the thalamus. Motor paralysis, sensory disturbances, and ataxia are typically absent or mild. While vestibular dysfunction has been implicated in the onset of TA, a comprehensive evaluation strategy that considers vestibular function has yet to be established. In this report, we present a case of TA following a left thalamic infarction where the patient exhibited no abnormalities in their subjective vertical visual (SVV) function, which is often used as an indicator of vestibular function, and we discuss the potential utility of the modified Clinical Test of Sensory Interaction and Balance (mCTSIB) in patients with TA.
丘脑性站立不能（TA）是一种由于丘脑单侧病变导致难以维持直立姿势的病症。通常不存在运动麻痹、感觉障碍和共济失调，或症状较轻。虽然前庭功能障碍被认为与TA的发病有关，但尚未建立一种考虑前庭功能的综合评估策略。在本报告中，我们介绍了一例左丘脑梗死后发生TA的病例，该患者的主观垂直视觉（SVV）功能（常被用作前庭功能指标）未表现出异常，并且我们讨论了改良的感觉交互与平衡临床测试（mCTSIB）在TA患者中的潜在应用价值。
