dysdiadochokinesia

(dis´dīad´ōkōkinē´zhə, -zēə),
n a disturbance of musculoskeletal function. There is a disorganization in the reciprocal innervation of agonists and antagonists and a loss of the ability to stop one act in terms of rate, magnitude, and the direction of movement and immediately to follow it with another act diametrically opposite (e.g., alternately elevating and depressing the mandible). Another example is observed in the inappropriate use of the tongue during mastication when it is necessary to change, reverse, and modify the energy and direction of movement.
