pupil size & shape
1. patient looks at you & you assess size & shape
2. compare to pupil gauge = normal is 2-6 mm
Abnormal = mitosis < 2 (eye drops), mydriasis >6 (drops, midbrain lesions, hypoxia, oculomotor damage); oval pupils (head injury, intracranial hemorrhage or pressure); aniscoria=unequal (congenital, medication, SNS or PNS destruction, eye surgery or trauma)
Reaction to light/consensual reaction (CN?)
1. dim lights & have them focus across the room
2. move penlight from outer edge of eye & then move into one eye and then the other
3. assess for change in size of both pupils
Abnormal = dysfunction of oculomotor nerve CN III or a mass in the brain; fixed or dilated=herniation of the medial temporal lobe
Accommodation (CN?)
1. patient focus on something in distance
2. Then patients focus on something close
distance = dilation; close = constrict
Abnormal = dysfunction of oculomotor nerve CN III or a mass in the brain; fixed or dilated=herniation of the medial temporal lobe
confrontation test
1. patient & nurse hold card over same eye, stand 2-3 feet apart.
2. move finger or pencil from periphery to median & when can patient see it?
Normal = 50-90°
Abnormal = if they can't see it same as you then peripheral field loss. if 20° or less then legally blind
Extraocular Muscle movement (CN?)
1. stand in front of patient 10"-12". have them follow your finger, with their eyes, while moving to 6 points.
Abnormal = Nystagmus (involuntary movement of eye) or ptosis (drooping eye lid, caused by abnormal function of CN III)
Hirschberg test (corneal reflex test)
Test for strabismus (ocular misalignment)
1. patient stares straight ahead, nurse shines light at bridge of nose (12-15") & light should be reflected symmetrically in eyes.
Abnormal = asymmetrical --> weak extraocular muscles
Rinne test
1. Place vibrating tuning fork on mastoid bone (behind ear). Have patient say when they can no longer hear & then place fork just outside ear and have them say when they can no longer hear
Normal = longer air conduction than bone 2:1
Abnormal = BC > AC which means hearing loss. It will be sensorneural loss if AC > BC but less than 2:1
Weber's test
1. place tuning fork on top of head, midline, & ask which ear the sound is heard louder.
Normal = heard equally
Abnormal = if defective ear hears louder → conductive hearing loss. If unaffected ear hears louder → sensor-neural hear loss on the defective ear
Transillumination of the sinus area
Test when patient has sinus pain or congestion
1. darken room. shine light patrol to nose & midline to eye & you should see illumination on palate of mouth
2. shine light on supraorbital rim of eye and you should see illumination above eyebrows
Abnormal = sinus congestion, tumor or other blockage
Sensation of light touch
1. have patient close their eyes and lightly swipe cotton over 3 areas on both sides of the face (anterior scalp, paranasal & jaw)
Abnormal = ↓ or unequal sensation which may indicate nerve damage
1. place your finger on the joint & have patient open & close their mouth
Abnormal = clicking with pain???
Tinel's sign
1. Tap firmly on palmer surface of the wrist where the median nerve passes thru the carpal tunnel
Abnormal = tingling sensation or pain → carpal tunnel syndrome
Phalen's test
1. Patient presses dorsal surface of both hands together for 1 minute.
Abnormal = numbness, paresthesia or pain → carpal tunnel syndrome
goniometer: Elbow joint
Purpose: used to measure ROM
Abnormal = rheumatoid arthritis; tenderness with pronation or supination or lateral side = tendonitis or epicondylitis (tennis elbow); medial side tenderness = medial tendonitis (golfer's elbow)
Romberg's test
purpose: cerebellar function
1. patient stands with feet together, arms at their side, eyes open & then closed
Abnormal: patient sways with eyes opened & closed. Causes = stroke, parkinson's or inner ear problems
Cerebellar function in LE: balance & coordination
tests for balance & coordination
- patient closes eyes & stands on 1 foot, then the other. S/B able to maintain for 5 seconds.
- hop on 1 foot, deep knee bends or walk on toes & heels
Coordination: patient is supine & drag heel from knee to ankle
Abnormal = cerebellar tumors, stroke, Parkinson's or inner ear problems
Two-point discrimination
1. Patient has eye closed & can they distinguish between one point or two, alternate touching
Abnormal = impairment of sensory (afferent nerves) or parietal lobe
Thomas test
Purpose: evaluate flexion contractures of the hip
1. patient is supine, bring flexed knee to chest. other leg should remain on table.
Abnormal: other leg lifts → hip flexion contracture. tightness of psoas muscle
Straight leg raise test (CN?)
Purpose: evaluate for nerve root irritation or lumbar disk herniation
1. patient is supine, raise one leg (keep knee straight), may feel tightness in hamstring but no pain)
Abnormal = sciatic nerve impingement, pressure on peripheral nerve.
Rapid alternating movements (coordination)
Patient rapidly pronates & supinates hands while touching thighs
Abnormal = Dysdiadochokinesia, caused by lesions to the cerebellum, MS
Achilles reflex
1. Place one hand under the sole & dorsiflex the foot. Then strike the Achilles tendon.
Normal = causes plantar flexion of foot (contraction os gastrocnemius muscle)
Abnormal: Diabetes, abnormal muscles, sensory neurons, lower motor neurons & neuromuscular junction,
Reflex: graded on scale of 0-4
Babinski's reflex
Start at lateral aspect of foot (near the heel) and stroke upwards & over to the medial aspect
Normal = plantar flexion of all toes
Abnormal = dorsiflexion of great toe with fanning of other toes → upper motor neuron, like a spinal cord injury or stroke
DTR: Brachioradial reflex (SN?)
C5 & C6
Hold arm with hand slightly pronated, tap the brachioradialis tendon 1-2 inches above the wrist.
Normal = muscle contraction in the forearm
Abnormal = hyperactive → stroke/head injury, Lou Gerhig, MS or hypoactive → trauma to a nerve or herniated disk in the back
DTR: Patellar reflex (SN?)
L2, L3, L4
tap patellar tendon
