| definition |
小脑共济失调是指由于小脑功能障碍导致的共济失调。这引起了各种基本的神经缺陷，包括协调不能（缺乏肌肉，四肢和关节之间的协调），辨距障碍（缺乏判断距离能力，可导致抓握运动时不能达到或超过目标），和轮替运动障碍（不能进行需要拮抗肌群反复切换开关的快速运动）。 Ataxia describes a lack of coordination while performing voluntary movements. It is associated with damage to the cerebellum or its afferent or efferent pathways. It may appear as clumsiness, inaccuracy, or instability. It may affect any part of the body. Cerebellar ataxia refers to ataxia due to dysfunction of the cerebellum. This causes a variety of elementary neurological deficits including asynergy (lack of coordination between muscles, limbs and joints), dysmetria (lack of ability to judge distances that can lead to under- oder overshoot in grasping movements), and dysdiadochokinesia (inability to perform rapid movements requiring antagonizing muscle groups to be switched on and off repeatedly). |
