NM 1.1, 1.2, 1.3 + Lab

In what order should you test sensory functions?

Superficial, Deep sensory modality, Combined cortical sense

sensation entered the spinal cord via _____ roots

dorsal

What 5 sensations is the DCML system responsible for?

localization, proprioception, kinesthesia, vibration, 2 pt discrimination

the Anterolateral spinal thalamic tract is responsible for what 3 senses?

pain, temperature, light touch

the spinocerebellar tract fxn

fine coordination of posture and kinesthetic sense of limbs

the deep sensations come from which tract?

DCML

what is the difference between sensation and perception?

sensation refers to the ability to recognize a stimulus where perception is the ability to organize, process, and interpret information

deficits in perception/awareness are most often see in a lesion in what lobe?

right lobe

a patient with a frontal lobe lesion would have issues with motor planing, and reasoning as well as . . .

cognitive and behavioral issues, lacking insight, taking things at face value

a patient in the clinic has a R side parietal lobe stroke, what deficit might they present with?

Left Neglect

what are the 3 superficial sensations?

pain, temperature, light touch

what are the 3 deep sensations?

proprioception, kinesthesia, vibraiton

what are the 6 combined cortical sensations?

stereognosis, tactile localization, 2pt discrimination, barognosis, graphesthesia, extinction

somatognosia

lack of awareness and recognition of own body structure

if a patient is having trouble identifying L vs R on their own body and the therapists they might be experiencing what?

Right/Left discrimination

anosognosia

denial, neglect, or lack of awareness of the severity of their own condition (think they have higher capabilities than they actually have)

how would you test form constancy?

have patient pick out an object from a group of similar shaped but different sized objects

topographical disorientation

navigating places

agnosia

inability to recognize familiar objects with certain sensory modalities. (ex: can identify a clock by its ticking but not by sight)

apraxia

inability to execute a multistep motor plan

ideomotor apraxia

Patient can not perform the task on command but can do the task when left on own

Ideational apraxia

Patient can not perform the task at all, either on command or on own

a patient comes into the clinic with apraxia. What two ares of the brain do you suspect a lesion in?

pre lateral frontal cortex and somatosensory association cortex

a right hemisphere lesion could lead to what form of apraxia?

dressing apraxia

number alexia

difficulty recognizing symbols/do computations (L side lesion)

visuospatial deficits

cannot orient self to changes in environment (R hemisphere lesion)

Slow in organization and performance: L or R side Lesion

L

rapid performance, short attention span, impulsive behavior, decreased safety: L or R Side Lesion

R

someone is aware of their deficits, and Amy have depression or anxiety. what side of ht hemisphere do they have a lesion on?

L

pt comes in with impaired judgement and impaired insight into their condition. What side do you expect their lesion to be on?

R

what training task is beneficial for those with sensory perceptual issues?

visually searching for and attending to environmental cues so that perceptual deficits can be corrected.

your patient has a LMN lesion. do they have a better chance of getting sensation back than an UMN lesion?

No. the UMN lesion has a better chance of regaining sensation

what is the purpose of the vestibulo-oculomotor screen?

to asses for potential CNS findings.

a positive _____ ___ _____ is considered a sinister abnormal CNS finding

test of skew

when progressing walking, what should you vary first?

hand support - because its the most functional, and allows you to move quicker
