Dysmetria

Dysmetria (Greek: "dificult to measure") is a symptom exhibited by patients after cerebellarinjury. This symptom manifests as a difficulty in accurately performing intentional movements. One of the functions of the cerebellum is to integrate position of the limbs with movement intention, resulting in a necessary constant fine-tuning of movements. A person exhibiting dysmetria would not be able to make such adjustments and would have a difficult time with many manual tasks.
