The Semont maneuver is a medical exercise that is used to treat the symptoms of vertigo, according to WebMD. The treatment is done at the direction of a doctor or therapist.
MedicineNet.com describes vertigo as the sensation of rocking or spinning even when completely still. It has many causes but is usually caused by ear infections or the displacement of small crystals within the inner ear, thereby irritating the hairs deep within the semicircular canals of the ear that affect balance. WebMD explains that the Semont maneuver involves 10- to 15-minute sessions of moving the head in different positions in order to move the crystals out of the ear canal, thus helping to relieve the symptoms of vertigo.
