Motor Impairments: Cerebellar Pathology Flashcards
How does ageing relate to coordination impairments?
decreased strength
slowed reaction time
decreased ROM
postural changes
Cerebellar Pathology: ASTHENIA
Generalized muscle weakness
Cerebellar Pathology: ASYNERGIA
Loss of ability to associate muscles together for complex movement
Cerebellar Pathology: DYSARTHRIA
difficult speaking
Cerebellar Pathology: DYSDIADOCHOKINESIA
impaired ability to perform rapid alternating movements
Cerebellar Pathology: DYSMETRIA
inability to judge the distance or range of a movement
Cerebellar Pathology: DYSSYNERGIA
movement performed is a sequence of parts rather than a single smooth activity; decomposition
- MOVEMENT IS NOT SMOOTH, IT IS SEPERATED
Cerebellar Pathology: GAIT DISORDER
ataxic pattern: wide BOS, postural instability; high UE
- CAN ADD WEIGHT TO DISTAL EXTREMITIES FOR SENSORY INPUT TO COMBAT ATAXIA
- Limb loading for more proprioceptive feedback enables to limb to control movement
Cerebellar Pathology: HYPOTONIA
Decrease in mm tone
- DISRUPTION OF AFFERENT INPUT FROM STRETCH RECEPTORS AND/OR LACK OF CEREBELLUM’S FACILATORY EFFERENT INFLUENCE
Cerebellar Pathology: HYPERMETRIA
Overestimation of distance or range needed to accomplish a movement
Cerebellar Pathology: HYPOMETRIA
Underestimation of distance or range needed to accomplish a movement
- VISUAL SYSTEM IMPACTED: MAGNIFICATION OF VISION
Cerebellar Pathology: NYSTAGMUS
Rhythmic quick oscillatory back and forth movement of the eyes
Cerebellar Pathology: REBOUND PHENOMENON
Inability to halt forceful movements after resistive stimulus removed; patient unable to stop sudden limb movements
- CHECK REFELX
Cerebellar Pathology: TREMOR
Involuntary oscillatory movement resulting from alternating contractions of opposing muscle groups
Cerebellar Pathology: INTENTION TREMOR (KINETIC)
Oscillatory movement during voluntary motion: increases osalim nearest target diminished or absent at rest
Cerebellar Pathology: POSTURAL TREMOR (STATIC)
Exaggerated Oscillatory movement of the body and standing posture or of a limb held against gravity
Cerebellar Pathology: TIBUATION
rhythmic oscillations of the head; axial involvement of the trunk
