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.
Crystal Drift Detection
Head-Turn Vertigo Reveal
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.

Pinpointing the Cause
Nystagmus Noted, Balance Mapped
Gold-Standard BPPV Identifier
Knowing when to seek help matters. While sensorineural hearing loss is often gradual and manageable, certain patterns signal the need for prompt specialist review to rule out treatable or serious causes.
You should get assessed if hearing changes occur suddenly, affect one ear, are accompanied by pulsating sounds, severe dizziness, facial weakness, visual disturbance, new neurological symptoms, or follow infection, head injury, or new medication use. Prompt review ensures timely diagnosis and appropriate management of early care.
Precision Positioning for Vertigo Clarity
At Harley AVM, assessment starts with a detailed clinical history to understand how hearing has changed, whether symptoms are gradual or sudden, and how they affect communication and daily life. We explore associated features such as tinnitus, imbalance, noise exposure, medical history, and medication use. This step helps us decide which investigations are appropriate and avoids unnecessary testing.
Depending on symptoms, assessment may include pure-tone audiometry, speech audiometry, speech-in-noise testing, tympanometry, acoustic reflex threshold measurement, eustachian tube function testing, and otoacoustic emissions. All testing is reviewed with our senior audiovestibular clinician, ensuring results are interpreted within the full clinical picture.
