What does the stenger phenomenon help us verify

How is the stenger phenomenon test given

Back 8

Present 2 tones of same frequency simultaneously. 10db above threshold in "Better" ear and 10bd below threshold in "bad" ear

Front 9

How do you interpret the results of the stenger phenomenon

Back 9

A response means they really have a hearing loss. A lack of response means they are faking because they only precieve the sound in the "good" ear and they don't WANT to respond to that one

Front 10

Has a Slow and fast phase

Front 13

Nystagmus is named by

Back 13

direction of fast phase

Front 14

The greater the angles of the slow phase....

Yes

Front 16

What is VOR

Back 16

Vestibulo-ocular reflex

Front 17

How do we test VOR

Back 17

Oculomotor testing in ENG or rotary chair

Front 18

Why is VOR important

Back 18

Helps us maintain focus on an object while moving

Front 19

What are calorics

Back 19

Bi-thermal air or water to the ear canals to stimulate the SSC and produce nystagmus response COWS

Front 27

What is absolute latency

Back 27

Time of a given peak

Front 28

What is interpeak latency

Back 28

Time between two peaks

Front 29

How does stimulus intensity affect the abr

Back 29

As intensity decreases the latency shifts

What will a SNHL look like in an abr

Back 31

Morphology changes, amplitudes reduced, waves absent, absikutle interpeak latencies are unaffected
