What arteries supply the cerebellum
Vertebral artery
Posterior Inferior Cerebellar Artery (PICA)
Basilar artery which splits into the:
Anterior Inferior Cerebellar Artery (AICA)
Superior Cerebellar Artery (SCA)
Common symptoms of cerebellum strokes
Nausea
Vomiting
Ataxia (coordination)
Diplopia
Headache
What are cerebellum strokes usually mistaken for
GI issues
What is the function and blood supply of the anterior lobe of the cerebellum
Regulation of muscle tone
Coordination of voluntary movement
SCA, AICA
What is the function and blood supply of the posterior lobe of the cerebellum
Planning of voluntary activity
PICA
What is the function of the FN lobe of the cerebellum
And what is the FN lobe
Balance
Controls eye movements
Flocculo-Nodular Lobe
What is coordination/Dexterity
Precise movements and able to fractionate without thinking about it
What are the 3 different types of impaired coordination
Problems initiating movement (reaction time)
Slowed movement time
Problems terminating movement
What are some coordination tests
Finger to finger/Finger to nose
Finger tapping
Heel to shin test
Forearm pronation/supination
Rebound test
Reflex
What can be observed in movement with ataxia pt
Struggling to initiate/terminate movement
Slow movement
Jerky
Do ataxia pt have problems with gait? If so, what can be observed with their gait
Yes
Wider BOS
Waddle
Need gait aids
What is dysmetria
Type of ataxia where a limb overshoots AND undershoots a target
What is Hypometria
Undershoots target
What is Hypermetria
Overshoots target
What is dysdiadochokinesia
Impaired performance of rapidly alternating movements (e.g wrist pronation/supination test)
What is bradykinesia
slow movement
What is hypokinesia
Reduced ROM with movement
What is Akinesia
Lack of/unable to perform movement
