Discussion Board Midterm Flashcards
how can a pt present with hypotonicity in the trunk but hypertonicity in the limb with a cerebellar lesion?
cerebellar regulation of axial mm is disrupted –> hypo
limb compensate –> hyper
why are multijoint movements challenging for pts with cerebellar lesions?
feedforward
balance
disconnect b/t vestibular syst
when can a phrenic nerve stimulator be used?
for pts that has LMN paths in tact
type 1 Chiari malformation
most common
cerebellum is pushed into foramen magnum
type 2 Chiari malformation
both the cerebellum and brain stem protrude into the foramen magnum
type 3 Chiari malformation
most severe
cerebellum and brain stem protrude into the SC
what is “boosting”?
practice of some athletes with spinal cord injuries where they purposefully inflict a state of autonomic dysreflexia in order to gain a competitive advantage
what SC syndrome can be d/t syringomyelia? how does it present?
central cord syndrome
UE > LE
mainly in C spine
what is the most common hereditary ataxia?
Friedreich ataxia
main PT conditions with autonomic neuropathy
gait deviations to velocity & balance
incorporate other med team
T/F: ALS pts usually have impaired cognition
F!!
ALS sx
UMN & LMN
UMN: pathological reflexes, spasticity, clonus
LMN: weakness, atrophy, fasciculations
what leads to a worse prognosis for Guillain Barre?
Diabetes, hypertension, requiring ventilatory support, and abnormal renal and hepatic function
Guillain Barre usually has a fully recovery within _____
1 year
sx must last ____ weeks for AIDP and ____ weeks for CIDP
AIDP - <4 weeks
CIDP - >8 weeks
what is the time frame for tPA?
3.5-4 hrs
Orpington Prognostic Scale
used to assess both the severity and prognosis of recovery from stroke;
1.6 to 6.8 and are based off of 4 items – motor deficits in arm, proprioception (eyes closed), balance, and cognition
Orpington Prognostic Scale categories
<3.2: mild impairments / high likelihood of returning home
3.2 to 5.2: moderate impairments / would respond better to rehabilitation
>5.2: severe impairments / dependent with an increased risk of institutionalization
The JFK coma/near coma scale is a standardized and systematic scale used to differentiate between rancheros levels ____. This scale is more sensitive to detecting change and can differentiate between ____and ___
1-3
coma and minimally conscious state
how does exercise benefit AD?
anti-inflammatory (T cells)
decrease oxidative stress
improve cognition
what is Sympathetic storming, also called neurostorming and paroxysmal sympathetic hyperactivity?
occurs after a TBI when the sympathetic nervous system becomes too active and the body cannot determine whether it is in danger
sx of hemorrhage post tPA
severe headache, severe hypertension, worsening neurological exam, & nausea/vomiting
NIHSS scoring
21-42: severe
16-20: moderate-severe
5-15: moderate
1-4: minor
0: no stroke symptoms
what is neuroradiological intervention?
placing small, thin metal coils into the aneurysm via a catheter inserted through an artery in the groin
