Dysmetria

Dysmetria (Greek: "difficult to measure") is a symptom exhibited by patients after cerebellar injury or injury to proprioceptive nerves (nerves that carry information about the position of joints and extremities).

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 is unable to make such adjustments and has difficulty with many manual tasks.

An upper motor lesion may cause dysmetria.
