Neurological System Flashcards
reflexes
deep tendon reflex, superficial or cutaneous reflex, pathological reflex
deep tendon reflex
elicited by tapping a tendon
superficial or cutaneous reflex
obtained by stimulating the skin
pathological reflex
usually present only in disease
reflex scale
0: no response 1+: low normal, slightly diminished 2+: normal 3+: more brisk than normal, not indicative of disease 4+: brisk, hyperactive, clonus
Biceps
palpate the biceps tendon in the antecubital fossa, place your thumb on the tendon, strike your thumb with the hammer
normal response: palpable flexion of the elbow
Triceps
flew elbow 90 degrees, strike tendon directly, just above the elbow
normal response: palpable extension of the elbow
Supinator or brachioradialis
strike tendon directly
1-2 inches above the wrist
expected response: flexion of the elbow and supination of the forearm
ASSESS BILATERALLY ALL REFLEXES
Knee
strike patellar tendon directly
normal response: leg extends and quads contract
Ankle
Slightly dorsiflex foot
strike achilles tendon directly
normal: plantar flexion
Babinski (plantar reflex)
cutaneous reflex
stroke sole on lateral edge and across ball of foot
normal: toes flex or remain still
abnormal: fanning of the toes, extension of great toe, may indicate a pyramidal tract lesion
relfex normal in infants < 1
assess motor coordination
gait: manner or style of walking
gait should me smooth, regular rhythm, symmetrical in stride lengths
abnormal gait could be intoxication, risk for injury, neuromuscular disorder
heel to toe: walk heel to toe in a straight line; this will exaggerate any unexpected finding in gait evaluation
assess muscle strength
upper and lower extremities
ask client to flex muscle and then resist when you apply opposing force
Muscle strength scale
0: no movement at all
1: Muscle contracts, but no movement
2: Extremity can move, but not against gravity
3: Full ROM against gravity, but not resistance
4: Full ROM against moderate resistance
5: Full ROM against gravity and resistance
Romberg Test
instruct client to stand, feet together, arms at sides, eyes open and then closed. be sure to protect from falling. slight swaying is normal. loss of balance is a positive test and indicates cerebellar ataxia or vestibular dysfunction
