Diadochokinesis

Diadochokinesis ( Greek διαδέχομαι "detach oneself, follow" and κινεῖν "move") describes the ability to move in rapid succession, for example rotating the forearm in and out ( pronation and supination ), as is necessary when changing a light bulb is to be performed repeatedly. If this ability is missing, one speaks of adiadochokinesis , and bradydiadochokinesis when the movements are slowed down alone . If movement is restricted beyond the speed of execution, this is known as dysdiadochokinesis .

Such restrictions of movement belong to the ataxias . They occur as symptoms of diseases of the brain regions that control fine motor skills, for example as a result of a stroke , Parkinson's syndromes (here in particular bradydiadochokinesis) or cerebellar diseases .
