W2 - Neuro: Sensort & Coordination Tests Flashcards
How is defending information received
Information is transferred from the CNS to the via descending, efferent tracts (they go down & send information from the brain)
What are the 4 main descending tracts
Lateral corticospinal = voluntary movement of limbs
Anterior corticospinal = axial muscles of the trunk & proximal limbs
Reticularspinal = voluntary movements, reflexes & muscle tone
Vestibulospinal = balance & extensor muscles. Orientation of the head in space
What do you use to measure strength tests
Oxford scale
What are myotomes
Related to a specific muscle activity provided by a specific nerve root
You can assess strength in a myotomal pattern
ONLY look at myotomal patterns if someone has a problem with their spinal cord or PNS
How is information transferred from our spinal cord to the thalamus
Ascending afferent tracts (they go up and bring information to the brain)
What are the 4 main ascending afferent tracts
Dorsal column = proprioception, vibration, discriminative touch
Lateral spinothalamic = pain & temp
Medial spinothalamic = pressure & crude touch
Spinocerebellar = proprioception
What spinal tract localises touch & identifies light & deep touch
Medial spinothalamic
What spinal tract identifies sharp & blunt, 2 point discrimination & stereognosis
Dorsal column
What tract identifies hot & cold touch
Lateral spinothalamic
What tract identifies proprioception
Spinocerebellar
What are dermatomes
An area of sensation provided specifically by specific nerve roots
ONLY asses dermotomes if a patient has a spinal cord orPNS problem
Name some coordination tests
Finger to nose
Heel to shin
Rapid alternating movements (diadochokinesia)
What do deep tendon reflexes asses
The monodynaptic reflex arc
