Dix-Hallpike Tests in London

The Dix-Hallpike test is used to diagnose Benign Paroxysmal Positional Vertigo or BPPV. BPPV is one of the most common types of inner ear disorders and typically produces a sudden sensation of dizziness or spinning when a person moves their head into certain positions. This is believed to be the result of tiny crystals of calcium carbonate detaching from their normal position within the ear and floating into the semicircular canals where they shouldn’t be. Harley St AVM provide simple and reliable Dix-Hallpike tests in London that are considered the gold standard for diagnosing BPPV.

What to Expect During a Dix-Hallpike Test

You can expect a Dix-Hallpike test at Harley St AVM to unfold in the following manner:

  • Following history and other assessment, one of our very experienced doctors will have you seated on examination couch .
  • The doctor will then ask you to turn your head at a 45° angle.
  • While turning your head you will be asked to keep your eyes open.
  • Next, the doctor will hold your head and assist you in leaning back and lying down with one ear pointing toward the floor.
  • You will need to remain in this position for 30 seconds to a minute with the doctor supporting the weight of your head to prevent neck strain.
  • While you are in this position the doctor will observe your eyes for signs of nystagmus.
  • After carefully observing your eyes the doctor will help you sit back upright and relax.

Nystagmus is a condition that causes involuntary eye movements. It is also a reliable indicator of BPPV provided that the nystagmus is accurately interpreted by a specialist like our medical doctors. BPPV can sometimes also be diagnosed with the presence of typical nystagmus and your specialist will be able to guide you on this.

Nystagmus can also be due to other causes such as problems with the brain or brain tumours and hence, accurate assessment by a specialist is important.
