motor function Flashcards
function cerebellum
motor planning and control
flocculonodular lobe role
balance, eye movement
flocculonodular lobe functionally known as
vestibulocerebellum
vermis and paranormal do what
gross limb movement
functionally vermis and paranormal region known as
spinocerebellum
lateral cerebellar for
fine and distal limb movement
lateral cerebellar also known as
cerebrocerebellum
if issues in flocculonodular lobe
nystagus
balance
truncal ataxia
if issues in verbal or paravermal
ataxic gait, truncal gait
dysarthria
limb ataxia (PT coordination tests)
PT coordination tests effect what
vermal / paravermal /spinocerebellum
lateral cerebellar injury happens how
falls backwards
two hereditary ataxias
friedreichs
spinocerebellar ataxia
acquired cerebellar ataxia
tumours, stroke, trauma
T/F movement disorder common to all cerebellum lesions
t
ataxia
uncoordinated voluntary movement
jerky
ataxia may result from
cerebellar pathology
somatosensory deficit
loss of sensory input from what
somatosensory deficits
dysmetria
can’t judge distance (hyper is too far, hypo too little)
intention tremor
not true tremor
tremor during voluntary movement
dysdiadochokinesia
rapid alternating movement difficulty
coordination test for dysmetria
finger to nose
coordination test for intention tremor
finger to nose or heel to shin
impact on function cerebellar ataxia
uncoordinated voluntary movement decreased posture increase fall risk dysarthria impaired gaze stability wide BOS decreased protective reaction
UE coordination assessment
finger thumb opposition
finger to nose
alternate pro/sup
LE coordination assessment
alterate foot tap
heel shin
what do if positive coordination assessment
assess somatosensation to differentiate sensory and cerebellar ataxia
two approaches to PT in cerebellar ataxisa
restorative and compensentory
restorative approach
improve function by application techniques with adaption
balance, walking and ocular exercises
is restorative or compensentary better
restorative
how to progress exercises cerebellar ataxia
dec guidance no of fixed points more active ROM increase speed change direction
cerebellar ataxia do we work on trunk control
yes through core and posture exercises
