Cerebellar Pathology Flashcards
Loss of ability to associate muscles together for complex movements
Asynergia
Increased time required to initiate voluntary movement
Delayed reaction time
Disorder of the motor component of speech articulation
Dysarthria
Impaired ability to perform rapid alternating movements
Dysdiadochokinesia
Inability to judge the distance or range of a movement
Dysmetria
Movement performed in a sequence of component parts rather than as a single, smooth activity; decomposition
Dyssynergia
Ataxic pattern; broad base of support; postural instability; high-guard position of UEs
Gait disorders
Decrease in muscle tone
Hypotonia
Overestimation of distance or range needed to accomplish a movement
Hypermetria
Underestimation of distance or range needed to accomplish a movement
Hypometria
Rhythmic, quick, oscillatory, back-and-forth movement of the eyes
Nystagmus
Inability to halt forceful movements after resistive stimulus removed; patient unable to stop sudden limb motion
Rebound phenomenon
Generalize muscle weakness
Asthenia
Involuntary oscillatory movement resulting from alternate contractions of opposing muscle groups
Tremor
Oscillatory movement during voluntary motion; increases as the limb nears target; diminished or absent at rest
Intention (kinetic) tremor
