Dysmetria

A lack of coordination of movement.

Dysmetria is the lack of coordination involving both the arms and legs. Due to scarring in the brain caused by MS, estimating the movement or completing certain functions can be troublesome. Typically, people with dysmetria under- or over-shoot the position of the hand, arm, leg or eye. Tasks such as writing and picking things up can become difficult or even impossible.
