![]() ![]() The doctor holds you in this position for 30 seconds. When your head is on the table, you are now looking down at the table. The doctor then quickly moves you to the other side of the table, without stopping in the upright position.When your head is on the table, you are looking up at the ceiling. The doctor then lowers you quickly to the side that causes the worst vertigo.The doctor turns your head so that it is halfway between looking straight ahead and looking away from the side that causes the worst vertigo.First, you sit on the exam table with your legs hanging off the edge.When your head is firmly moved into different positions, the crystal debris (canaliths) causing vertigo moves freely and no longer causes symptoms. A single 10- to 15-minute session usually is all that is needed. The Semont maneuver is done with the help of a doctor or physical therapist. It can be done by your doctor, an audiologist or a physical therapist and involves maneuvering the position of your head. Treat the most symptomatic side with an Epley maneuver (Over half of positional vertigo problems are a posterior canal.The doctor will then help you to sit back up with your legs hanging off the table on the same side that you were facing. A technique called canalith repositioning (or Epley maneuver) usually helps resolve benign paroxysmal positional vertigo more quickly than simply waiting for your dizziness to go away.So you have a vertigo patient in your clinic…what do you do? Maybe the dizziness is coming from a vision or neck problem? Or a combination of these systems? Most horizontal and anterior canal positional vertigo problems are ‘sticky’ and require liberating techniques. Know which canal and side as each treatment needs to be specific to the involved canal Head position is critical in treating vertigo Reasons why positional vertigo treatments fail These maneuvers are necessary to successfully treat these canals. If your position changes of the head are too slow then the crystal settles back where it was.Ī lack of liberating maneuvers for an anterior canal or horizontal canal problem will fail to clear a crystal. Head position is CRITICAL in treating positional vertigo. If you do not properly position the canal in a dependent position with gravity and allow the crystal to fall and settle your treatment “will fail”. Christopher Chang, ENT comments on treatment of positional vertigo. These treatments do not follow the physics of moving a small crystal in a curved, fluid filled tube. Treatments that will NOT treat positional vertigo are a Brandt-Daroff exercise as well as Gyrostim. It will also return and can cause other symptoms in the meantime. Two small RCTs found that modified Epley maneuvers (3 times daily until symptoms resolved) resulted in symptom improvement in 64 to 95 of patients by 1 week. You or your patient will feel better but not fully, and now this problem is more difficult to find and to treat. Clinicians perform the classical Epley maneuver while patient self-treatment is the modified Epley maneuver. If you are unsure of the canal or side (remember there are 3 on each side) you can shift the crystal further down the semicircular canal, getting it stuck. This can be helpful but does not ‘fix’ the problem. A lot of cases of vertigo get better week by week without treatment as our vestibular nuclei shift their input to ignore this problem creating a unilateral vestibular hypo-function. The cool thing is this! As we continue to stimulate the cupula we see a blunting of the cupular response. It is this abnormal information that causes vertigo. What happens next is the cause of vertigo.Ī crystal starts to sink stimulating the cupula or sensing organ of it’s canal to fire while the other 5 canals are telling the brain that there is no movement of the head. ![]() The sensing organ, the cupula, stops its deflection telling the brain that there is no longer any acceleration changes to the head. When our head stops moving the endolymph or fluid in our semicircular canals settles. ![]() If they end up in the semicircular canals then vertigo can occur. If you have back or neck problems, the maneuver could cause injury. However, you should always see a healthcare provider before you attempt the maneuver at home. If they stay in the vestibule then there are no symptoms. The home Epley maneuver is safe for people without medical conditions that limit mobility. Over time pieces of the otolith can break off. Head injury or whiplash can create fractures in the Otolith crystals. ![]()
