Loss of coordination, though the power necessary to make the movements is still present. Thus an ataxic person may have a good grip in each hand but be unable to make any fine movements with the fingers; or, if the ataxia is in the legs, the person throws these about a great deal in walking while still being able to lift the legs and take steps quite well. This is due to a sensory defect or to disease of the cerebellum. (See FRIEDREICH'S ATAXIA; LOCOMOTOR ATAXIA.)
