neuroscreen for final Flashcards
When do you perform a neuroscreen exam
burns, diabetes, MS, joint injury, SCI, TBI, CVA, cervical/lumbar involvement
Upper motor nerve lesion
neurological condition from damage to corticospinal or pyramidal tract in the brain or spinal cord
results of UMNL
hemiplegia, paraplegia, quadriplegia depending on the location and extent
Lower motor neuron lesion (LMNL)
injury occurring in the anterior horn cells, nerve root cells or peripheral nervous system
LMNL results in..
diminished reflexes, weakness or flaccid paralysis and atrophy
Deep tendon reflex (DTR)
the reaction of muscle to being passively stretched by percussion on the tendon
What does DTR measure
the integrity of both efferent and afferent peripheral nerves and their central inhibitory controls
what might cause a nerve root lesion
herniated disc putting pressure on the nerve root
spinothalmic system tests
pain, temperature and crude touch
protective sensing is the test
dorsal column/medial lemniscal system tests
pressure, vibration, position sense, discriminative touch, movement sense Discriminative sensation is the test
Mechanoreceptors
mechanical pain
muscle spindle detects
changes of length AND rate of change
golgi tendon organs detect
muscle length change
Testing for peripheral nerve lesion/injury
test proximal to distal
testing central nervous system lesion such as CVA
test distal to proximal
