role of cerebellum (4)
Coordination of voluntary movement, Balance and posture, Muscle tone regulation, Fine motor control
Checks lower-limb coordination by asking a patient to slide the heel of one foot down the opposite shin in a smooth, controlled motion.
Heel-to-shin test
impaired coordination=cerebellar lesion
Autoimmune destruction of acetylcholine receptors at neuromuscular junctions. muscle weakness that worsens with acitivty
toes fan outward in adults → upper motor neuron lesion
babinski sign
Brain that deals with language comprehension
wernicke's area
a clinical evaluation of how someone walks, observing steps, posture, balance, and limb movement to identify abnormalities
gait assessment,
an ataxic gait is
wide and unsteady
signs and symptoms
ptosis, diplopia, weakness of facial muscles, dysphagia, dysarthia, fatigue
rhythmic contractions → upper motor neuron disorder
clonus
Brain that deals with speech production
broca's area
Assesses balance and proprioception by having a patient stand with feet together and eyes closed to observe for swaying or instability.
romberg test
a positive romberg test occurs when there is a
loss of balance with eyes closed,cerebellar or proprioceptive dysfunction
muscle weakness improves with
anti cholinesterase medication
spinal cord injury
hyperreflexia
Evaluates cerebellar coordination by asking a patient to alternately touch their nose and the examiner’s finger.
finger to nose test
difficulty reaching the target
Dysmetria
neuropathy, Guillain-Barre
hyporeflexia
Tests for dysdiadochokinesia by having a patient quickly perform alternating hand or finger motions.
Rapid alternating movements
inability to perform rapid alternating movements
Dysdiadochokinesia
