Remember, our brains don't come equipped with co-pilots. Vestibular rehab . Is like pilot instrument training It teaches the pilot how to compensate for bad balance situations. It helps him learn to perform well with what he has whether it be an engine out, a bad compass or foggy visual conditions. Variable lesions change without warning.
Symptoms come and go, vertigo attacks are episodic.
If the bad engine fluctuates without warning, then smooth sailing is out of the question. The plane may yaw and spin without warning leaving the pilot to play catch-up to salvage each episode. In these cases, if the engine can't be repaired, it is better to shut that engine down permanently rather than endure sudden violent attacks of vertigo. This may be accomplished through surgery. The idea is to shut off all impulses coming from the damaged ear to the brain.
