Motor Exam Flashcards
upper motor neuron lesions are these kind of injuries (peripheral, central)
central
location of UMNL
brain, spinal cord
these neuron lesions can be unilateral and bilateral
UMNL
these neuron lesions have spastic paralysis (functional nerve)
UMNL
lower motor neuron lesions are these kinds of injuries (central, peripheral)
peripheral
these neuron lesions are unilateral but affect one to many muscles and sensory regions
LMNL
these neuron lesions have flaccid paralysis (non-functional nerve)
LMNL
strength testing that has complete paralysis, 0% of normal movement, and no contraction
0/5
strength testing that has a twitch of muscle, 0-10% of movement, and can feel muscle action but don’t see movement
1/5
strength testing that has moderate to severe paresis, active movement can happen when gravity is eliminated, 11-25% of normal movement, patient can move joint through full ROM without gravity
2/5
strength testing that has moderate paresis, active movement against gravity, 26-50% of normal movement, and complete ROM against gravity
3/5
strength testing that has mild paresis, active movement against gravity and mild resistance, 51-75% of normal movement, usually resistance of 2 fingers
4/5
strength testing that has normal strength and 76-100% of normal movement
5/5

nerve root=C5
peripheral nerve=suprascapular

triceps muscle has this nerve root and peripheral nerve
nerve root=C7
peripheral nerve=radial
wrist flexors have this nerve root and peripheral nerve
nerve root=C7
peripheral nerve=median/ulnar
finger extensors have this nerve root and peripheral nerve

decreased muscle tone means this kind of neuron lesion
LMNL
increased muscle tone means this kind of neuron lesion
UMNL
hypertonia means
increased muscle tone
increased muscular resistance felt by examiner during quick joint movement
spasticity
involuntary muscular resistance felt when moving a resting joint and persists as the joint is moved through its entire ROM
rigidity
hypotonia means
decreased muscle tone
loss of normal neurological function
deficit phenomenon
exaggerations or perversions of normal neurological function due to a loss of cortical inhibition
release phenomenon
biceps reflex has this nerve root and peripheral nerve
nerve root=C5
peripheral nerve=musculocutaneous
brachioradialis reflex has this nerve root and peripheral nerve
nerve root=C6
peripheral nerve=radial
triceps reflex has this nerve root and peripheral nerve
nerve root=C7
peripheral nerve=radial
finger flexion reflex has this nerve root and peripheral nerve
nerve root=C8
peripheral nerve=median/ulnar
grading reflex that’s a 0 means
absent reflex
grading reflex that’s a 1 means
hypoactive reflex
grading reflex that’s a 2 means
normal reflex
grading reflex that’s a 3 means
hyperactive reflex
grading reflex that’s a 4 means
hyperactive reflex with sustained clonus
type of reflexes that are motor responses to scraping of the skin
superficial reflexes
superficial reflexes are graded as
present or absent
superficial reflexes can be abolished by
severe LMNL or destruction of sensory pathways from the skin
types of superficial reflexes
gag reflex, corneal blink reflex, epigastric reflex, upper/middle/lower abdominal reflex, cremasteric reflex, gluteal reflex, plantar reflex, anal reflex
innervation of gag reflex
CN 9 & 10
reflex that has elevation of soft palate, constriction of pharyngeal muscles
gag reflex
innervation of corneal blink reflex
CN 5 & 7
innervation of epigastric reflex
T5-T7
peripheral nerve of epigastric reflex
intercostal nerve
