Nursing the Spinal Patient Flashcards
why is a neurological exam performed?
breaks complex presentations into manageable steps
can localise disease
monitor progress or deterioration of disease
what are the aims of a neurological exam?

wide based stance
what is involved in sensory evaluation during a neuro exam?
deep pain
are deep pain and spinal reflexes the same?
no - spinal reflexes may be seen even if patient is DP -ve
what is one of the most common neurological presentations?
gait abnormality
what is assessed about a patients gait during assessment in a neuro exam?
can the animal generate and make coordinated movements
do they walk normally
is there any hopping/ataxia/dragging of a limb
how is gait analysis performed?
owner walks animal up and down
cats will be allowed loose in the consult room
what should be done during gait analysis if no attempt to walk is made / the patient is unable to walk?
sling/support should be used so they can be assessed and localisation performed
describe a head tilt
one ear is below the other
describe head turn
nose turned towards the body - head is still in line
describe ventroflexion of the neck
low head carriage
what is scoliosis?
lateral curve of the spine
what is lordosis?
inward curvature of the spine
what is kyphosis?
outward curvature of the spine
define decerebrate rigidity
extension of all limbs, head and neck in lateral recumbency
define decerebellate rigidity
extension of all thoracic limbs, head and neck
hind limbs flexed or flaccid (could still do ballet!)
what stages are involved in testing postural reactions?
proprioceptive positioning
hopping
visual placing
tactile placing
hemi-walking
wheelbarrowing
what aspects of the neurological system do postural reactions test?
sensory nerves
ascending tracts of spinal cord
ascending tracts of brainstem
forebrain
descending tracts of brainstem
descending tracts of spinal cord
motor nerves
muscles
what is the purpose of postural reactions testing?
screening test to localise a rough area
where are upper motor neurones located?
between the cerebral cortex and spinal cord
what is the role of upper motor neurones?
send signals to lower motor neurones
where are lower motor neurones located?
between the CNS and the effector organ
what is the role of lower motor neurones?
connect CNS to effector organ (muscle) and send signal to make them contract
what types of lesion can affect upper and lower motor neurones?
brain
spinal cord
how does a lower motor neurone injury present?
any reflexes are weaker or absent
muscle atrophy
severe muscle weakness
no or reduced muscle tone
flaccid paresis
how does an upper motor neurone injury present?
reflexes more exadurated and easier to elicit
inhibited reflexes may be seen
increase in muscle tone
muscle atrophy but chronic
what is assessed in the thoracic limbes during the spinal reflex section of a neuro exam?
withdrawal reflex
extensor carpi radialis
biceps brachii and triceps
what is assessed in the pelvic limbs during the spinal reflex section of a neuro exam?
withdrawal
patella
cranial tibial and gastrocnemius
what are the main spinal reflexes tested during a neuro exam?
thoracic limbs
pelvic limbs
perineal reflex
panniculus
what is the panniculus reflex?
shrugging or flinching of the skin adjacent to the spine when it is stimulated by pinching
how is the withdrawal reflex assessed?
gentle pinching of toes
does a withdrawal reflex indicate that the patient has pain perception?
no
what is the withdrawal refelx?
upon pinching limb is withdrawn upwards towards the body
how is the patella reflex checked?
patella hammer used below the patella
what is the patella reflex?
leg extension when area below patella is hit with patella hammer
how is the perineal reflex checked?
pinching or stroking around the anus
what is the perineal reflex?
contraction of the anal sphincter in response to stroking or pinching of perineum
what is tested by the cutaneous trunci reflex?
segmental nerves
spinal cord cranial to pinched area up to T1
lateral thoracic nerve
where is the cutaneous trunci tested?
alongside the spine either side until reflex is seen
what is the cutaneous trunci reflex used to for?
localisation
pre op measure is used post op to check for recovery or deterioration
is pain evaluation the same as withdrawal reflex?
no - withdrawal may be seen with no deep pain sensation
when are deep pain tracts affected by spinal cord injury?
