Ear Testing

Front 1

what does the hearing acuity test declare and how do you preform the test? what is normal response?

Back 1

pack one ear with cotton and close eyes, obtain a ticking clock or pocket watch and hold it close to upacked ear. move slowly away until the ticking is no longer audible. test declares whether your hearing is sharp or indefinite and whether or not both ears are equally sharp. normal response is to be able to hear for same distance of both ears.

Front 2

what does the sound localization test declare and how do you preform the test? what is normal response?

Back 2

declares if you can hear sound equally from different areas around you. you should be able to identify which direction the sound is coming from with eyes closed.

Front 3

what does the frequency range test declare and how do you test it? what is normal response?

Back 3

declares which frequencies your ears can pick up and cannot pick up and which were most comfortably heard.

Front 4

what does the deafness test declare and how do you test it? what is normal response?

Back 4

declares whether patient is going deaf in one ear or hears better with one ear rather than the other. You strike tuning for and place medially on partners head and tone should be equally loud for both ears.

Front 5

what does the conduction hearing test declare and how do we test it? what is normal response?

Back 5

declares whether the subject hears better by bone or by air conduction. you strike tuning for then place base on their mastoid process to test hearing by bone then do opposite ear except after striking put the prongs by ear to test for air conduction first before performing mastoid process to test for bone. if subject hears the tone again by bone conduction after hearing by air conduction is lost then there is some conduction deafness and result is recorded as a negative.

Front 6

what does the weber test declare and how do we test it? what is normal response?

Back 6

declares whether sound remains centralized (normal) or lateralizes to one side or the other (indicates some degree of conduction or sensorineural deafness)

Front 7

what does the rinne test declare and how do we test it? what is normal response?

Back 7

declares bone and air conduction hearing deafness. tests with striking prong and first placing base of prong on mastoid process to test for bone conduction then air conduction. test on opposite ear in opposite order. if conduction is heard on bone after air conduction is lost then there is some conduction deafness.

Front 8

what does the balance test declare and how do we test it? what is normal response?

Back 8

the ability to walk with balance and without dizziness, unless subject to rotational forces, indicates normal function of the equilibrium apparatus.. we test it by walking a strait line placing one foot in front of another.

Front 9

what does the barany test declare and what do we do to test for it? what is normal response?

Back 9

if subject is spinning to the left then his eyes initially should move slowly to the right then quickly to the left. (snapping back motion) tests to see if cupula is preforming correctly. (spinning chair test)

Front 10

what does the romberg test declare and what do we do to test for it? what is normal response?

Back 10

determines the integrity of the dorsal white column of the spinal cord, which transmits impulses to the brain from the proprioceptors involved with posture. stand with back to blackboard. draw line parallel to each side of partners body. should stand erect with eyes open and staring strait ahead for 2 minutes while you observe any movements. did you notice any gross swaying movements? repeat test with subjects eyes closed. record the degree of side to side movement. tests the equilibrium apparatus of the inner ear and whether it is operating equally well in all these tests along with the proprioceptors. (determines integrity of dorsal white column of the spinal cord, which transmits impulses to the brain from the proprioceptors involved with posture ONLY IMPORTANT THING TO NOTE)

Front 11

balance test?

Back 11

place 3 coins of different sizes on the floor and ask lab partner to pick coins up. observe muscle activity and coordination. was nystagmus present?

Front 12

sensation of dizziness and rotational movement when such movement is not occurring or has ceased?

Back 12

vertigo

Front 13

involuntary rolling of the eyes in any direction or the trailing of the eyes slowly in one direction, followed by their rapid movement in the opposite direction? normal after rotation, abnormal otherwise.

Back 13

nystagmus
