4.3.2 Therapeutic maneuvers: protocol proposal for the anterior canal
The maneuver selected is Lorin’s method. Here, the limit stop is kept in the fully retracted
position.
The patient is maneuvered in the same way as in the Dix-Hallpike maneuver, except that it is
extended until the patient’s head is fully downwards.
.
This position is held for 30 seconds, after which the patient is raised 45º in the opposite direction
every 30 seconds until verticalized again. In this way, a left anterior canal lithiasis will be treated,
commencing with a maneuver identical to the Dix-Hallpike maneuver for a right posterior canal
and, conversely, for the right anterior canal.
