Stenger Test – Hearing Test 6

The key terms of Hearing test 6 include, Stenger Test.


Stenger test

Sound is audible in both ears but the patient is only aware of it on the left ear where the SL is higher, called the stenger effect
so basically when a sound is presented to both ears the listener is aware of its presence only in the ear where it has a higher sensation level


When can stenger be used?
Positive test
negative test

Positive= faking, functional hearing loss
negative= not faking
need to have a 25 dB difference between ears


Psychogenic

Loss arising from psycho conditions
aka hysterical deafness


Non-organic hearing loss can be suspected when

Referral source is sketch
exaggerated behavior
threshold variability
disagreement in SRT/PTA more than 12 dB apart
lack of crossover
odd results


Behavioral tests for non-organic hearing loss

Ascending descending gap test
Stenger test
delayed auditory feedback tests
varying intensity story test
variable intensity pulse count method
yes-no method


Utricle senses

Straight line horizontal movement


Saccule senses

Straight line vertical movement


Stria vascularis

Supplies blood and nutrients to the organ of corti


Scala media has what fluid

Endolymph


Two sacs of the vestibular system
and what are they filled with

Utricle
saccule
endolymph


Semicircular canals sense

Rotation
one for each plane of movement


Symptoms of vestibular disturbance

Vertigo
nystagmus
anxiety
rapid heart rate
nausea and vomiting


Nystagmus

Involuntary rhythmic eye movement
– Usual
