Post-stroke hemichorea-hemiballismus (HCHB) typically manifests as hyperkinetic movements contralateral to the lesion, but rarely occurs ipsilaterally. In this article, we present a rare case who initially presented with left hemiparesis and developed right HCHB after right basal ganglia hemorrhage. To facilitate motor recovery in the left hemiparesis, we applied low-frequency repetitive transcranial magnetic stimulation (rTMS) over the left primary motor cortex. Unexpectedly, the right HCHB was significantly reduced after four weeks of therapy. Post-treatment perfusion imaging showed increased cerebral blood flow in the left middle cerebral artery territory. In conclusion, low-frequency rTMS may be considered an alternative therapy for post-stroke HCHB.
中风后偏侧舞蹈症-偏侧投掷症（HCHB）通常表现为病变对侧的运动亢进，但很少发生在同侧。在本文中，我们报告了一例罕见病例，该患者最初表现为左侧偏瘫，在右侧基底节出血后出现右侧HCHB。为促进左侧偏瘫的运动恢复，我们在左侧初级运动皮层应用了低频重复经颅磁刺激（rTMS）。出乎意料的是，治疗四周后右侧HCHB明显减轻。治疗后灌注成像显示左侧大脑中动脉区域脑血流量增加。总之，低频rTMS可被视为中风后HCHB的一种替代治疗方法。
