{"title":"La vidéonystagmoscopie (VNG) à Dudelange","content":"**Watching eye movements helps to understand certain forms of dizziness. At the Pôle Equilibre & Santé practice, Bloc A, 48 Rue de la Libération in Dudelange, the Framiscope (videonystagmoscopy) guides [vestibular rehabilitation](/dudelange/competence/reeducation-vestibulaire). It complements the clinical examination; it does not establish every diagnosis on its own.**\n\n## Why film nystagmus\n\nThe inner ear and the eye muscles are linked. When a semicircular canal dysfunctions, the eye beats. A painless infrared mask reveals these beats even when fixation is suppressed. These micro-movements escape the mirror: the camera makes them readable.\n\nCommon tests: spontaneous nystagmus, pursuits, Head Shaking, positional tests (Dix-Hallpike, roll tests). The profile points towards BPPV (otoliths in a canal), hypofunction of one ear, or a picture that belongs more to the physician (central sign). The Framiscope helps the vestibular physiotherapist: it is not an MRI.\n\n## From assessment to manoeuvres and exercises\n\nFor benign paroxysmal positional vertigo — brief vertigo when turning in bed — repositioning manoeuvres (Epley, Semont) are recommended first-line. Videonystagmoscopy helps identify the canal and check the effect. Beyond a few well-conducted attempts, the diagnosis is rediscussed.\n\nFor peripheral vestibular hypofunction, the heart of treatment remains rehabilitation: habituation, compensation, balance. The examination serves to choose and dose these exercises, not to replace them.\n\n## Preparation, session, driving\n\nQuiet room, light mask. Examination often **20 to 40 minutes** according to the tests. Brief vertigo may be provoked: that is sometimes useful for diagnosis, always supervised. Hold a support if needed.\n\nThe evening before and the morning: limit excessive caffeine and alcohol if you were asked to; bring your glasses; mention treatments (sedatives, anti-vertigo drugs) that can change the responses. Comfortable clothing. Prescription and useful ENT reports.\n\nAfter provoked vertigo: do not drive immediately if you are still unstable — wait until you are stable, or arrange to be accompanied. Desk work: according to symptoms. Pivot sport or heights: when balance holds on tests, often after several habituation sessions.\n\nResults: BPPV may resolve in one or two well-targeted manoeuvres. Hypofunction is judged over weeks of daily exercises. If the picture leaves typical peripheral vestibular territory, medical advice.\n\nRelative contraindications: severe cervical instability for certain manoeuvres, ocular pathology preventing the mask, unexplored acute neurological picture — the assessment guides.\n\n## Frequently asked questions\n\n\nHow should I prepare?\n\nGlasses, prescription, ENT reports. Mention anti-vertigo treatments. Limit excessive caffeine/alcohol if instructed. Plan a companion if you fear driving afterwards.\n\n\n\n\nHow long does the examination last?\n\nOften twenty to forty minutes according to the tests needed.\n\n\n\n\nWill you provoke vertigo?\n\nSometimes, briefly, to identify the canal or test a manoeuvre. It is supervised and stoppable.\n\n\n\n\nCan I drive afterwards?\n\nOnly if you are stable. After provoked vertigo, wait or arrange to be driven home.\n\n\n\n\nDoes VNG replace an MRI?\n\nNo. It guides vestibular rehabilitation. Central or atypical doubt belongs to the physician and possible imaging.\n\n\n\n\nWhat timelines, and is it reimbursed?\n\nBPPV: sometimes one or two manoeuvres. Hypofunction: weeks of exercises. On medical prescription, the [CNS](https://cns.public.lu/) covers the session according to the usual rules. The practice handles the paperwork. See [the physiotherapy consultation](/dudelange/kinesitherapie/consultation-kine).\n\n\n\n\nHow can I book an appointment?\n\nBy phone on [+352 26 65 15 33](tel:+35226651533).
