| definition |
意向性震颤是指出现于随意运动时的震颤。其特点是在有目的运动中或将要达到目标时最为明显，常见于脊髓小脑及其传出通路病变时。意向性震颤可以不伴肌张力的减低，只在肢体运动时才出现。 Intention tremor is a dyskinetic disorder characterized by a broad, coarse, and low frequency tremor evident during deliberate and visually-guided movement . An intention tremor is usually perpendicular to the direction of movement. When experiencing an intention tremor, one often overshoots or undershoots one's target, a condition known as dysmetria. Intention tremor is the result of dysfunction of the cerebellum, particularly on the same side as the tremor in the lateral zone, which controls visually guided movements. Depending on the location of cerebellar damage, these tremors can be either unilateral or bilateral. Cyclical movement of a body part that can represent either a physiologic process or a manifestation of disease. Intention or action tremor, a common manifestation of CEREBELLAR DISEASES, is aggravated by movement. In contrast, resting tremor is maximal when there is no attempt at voluntary movement, and occurs as a relatively frequent manifestation of PARKINSON DISEASE. |
