Alterations in sensory discrimination are a prominent nonmotor feature of dystonia. Abnormal temporal discrimination in focal dystonia is considered to represent its mediational endophenotype, albeit unclear pathophysiological correlates. We examined the associations between the visual temporal discrimination threshold (TDT) and brain activity in patients with musician's dystonia, nonmusician's dystonia, and healthy controls.

音乐家肌张力障碍的正常时间辨别与异常的感觉运动处理有关


感觉辨别的改变是肌张力障碍的一个突出的非运动特征。局灶性肌张力障碍的异常时间辨别被认为代表其中介内表型，尽管病理生理学相关性尚不清楚。我们检查了音乐家肌张力障碍患者、非音乐家肌张力障碍患者和健康对照组的视觉时间辨别阈值 (TDT) 与大脑活动之间的关联。
