Stenger’s, Chimani Moos, Teal test

SPECIAL TUNING FORK TEST FOR MALINGERING / NON- ORGANIC DEAFNESS

  1. Stenger’s test: It is based on the principle that if two equal/ identical sounds strike on the healthy ears, the individual hears it in only one ear – the one in proximity to the sound.
    Procedure : The patient is blindfolded and the examiner holds two similar tuning forks (512) struck with moderate intensity and held at 25 cm from each ear. The malingerer hears in the normal ear only. The fork on the deaf side is advanced by 3 inches towards the ear. A malingerer does not hear the sound at all.
  2. Chimani Moos test: This test is a modification of the Weber test to detect non-organic hearing loss. If a tuning fork is placed on the forehead, the malingerer states that he hears the sound in his good ear (simulating sensorineural deafness). If the meatus of the good ear is occluded, the truly deaf patient still hears the sound in the occluded ear but the malingerer will pretend that he is not able to hear the sound at all.
  3. Teal test: It is used in patients who claim to hear only by bone conduction.
