The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
With a one-sided conductive component the combined use of both the Weber and Rinne tests is useful. If the Weber test is used, in which a vibrating tuning fork is touched to the midline of the forehead, the person will hear the sound more loudly in the affected ear because background noise does not mask the hearing on this side.
Air conduction should be greater than bone conduction, so the patient should be able to hear the tuning fork next to the pinna (outer ear) after they can no longer hear it when held against the mastoid. This normal result is paradoxically called a positive Rinne test (as a positive medical test usually indicates an abnormality).

Romberg's test is positive if the patient falls while the eyes are closed. Swaying is not a positive sign as it shows proprioceptive correction. [4] Patients with a positive result are said to demonstrate Romberg's sign or Rombergism. They can also be described as Romberg's positive. The basis of this test is that balance comes from the ...
