what is Dismetria =

What is Dysdiadochokinesia =

Back 13

Over shoot the target while trying to catch it.
(Dysmetria (English: difficult to measure) refers to a lack of coordination of movement typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye. It is a type of ataxia. It is sometimes described as an inability to judge distance or scale)

What is Dysdiadochokinesia
= fast alternative movements have leison in cerebellum and they can not due to the leision

Hint 13

dys "bad", diadocho "receive", kinesia "movement"),
often abbreviated as DDK,
is the medical term for

impaired ability to perform rapid, alternating movements
