The patient is usually left with a sense of unsteadiness and dizziness after the acute episode.
The Romberg has traditionally been considered a test of proprioceptive function.
If this is negative, performing the sharpened Romberg may reveal subtle balance deficiencies undetectable with the ordinary Romberg test, especially in patients with acoustic tumors.
