When this may fit: When an assessed movement or lighting situation reliably brings on familiar symptoms and a clinician considers planned practice appropriate. [Specialist guidance; facial exposure efficacy uncertain]

If a certain movement or room lighting repeatedly starts a spasm, avoiding it may be the only workable choice for now. Planned practice is an optional way to explore whether a smaller, more manageable version becomes possible with support.
What does graded exposure mean here?
Exposure means encountering an identified situation; graded means adjusting it in steps. It does not mean enduring the strongest trigger. Facial specialist guidance discusses movement and light triggers, but controlled research has not established an effective dose for these facial symptoms. [1]
Before considering it, the team should assess why the situation causes difficulty. Eye pain, migraine, ocular disease, other movement disorders or a history of light-triggered seizures can change what is appropriate. Feeling worse in bright light does not establish a functional diagnosis.
Decide the goal before the practice
Perhaps the goal is to tolerate a comfortable room long enough to talk with a friend. Discuss which feature matters: glare, brightness, fatigue, facial effort or something else. Change one relevant feature at a time with the clinician’s guidance so the result is easier to interpret.
An illustrative plan might start in the person’s usual comfortable setting, with control of the lighting and a clear way to stop. The next step is agreed from their response, including later effects. There is no instruction here to increase brightness on a schedule.
For movement triggers, have the therapist select and demonstrate a small safe task. Do not repeatedly stretch into a spasm to make your nervous system “get used to it.” Force and prolonged provocation are not requirements.
Keep accommodations available
A visor, preferred lighting, breaks or remote participation may still be needed. Their use does not invalidate rehabilitation. Do not use flashing-light videos, stare into lights or hold an eyelid open. If a planned task worsens eye pain, vision or headache, stop and obtain advice rather than escalating it.
During a familiar flare, return to the comfortable setting or pause practice. A larger symptom response is not a better training session. You can decide with the team that this approach is not useful for you.
New or different symptoms: Sudden new facial droop or weakness, speech difficulty or other possible stroke symptoms need emergency assessment, even if they stop. Call your local emergency number; do not wait for an exercise to work. [3]

Let the person control the agreed environment and stopping point. Never switch on lights unexpectedly or provoke a movement to test their response. Ask before changing blinds, screens or seating.
Support access to the activity even if practice is paused. The visit or conversation should not depend on tolerating more light.

Identify the putative trigger and assess ocular, migraine, movement-disorder and seizure-related alternatives as indicated. Agree consent, adjustable intensity, stopping criteria and delayed-response review. Do not transfer exposure assumptions from another condition or interpret distress as proof that a task is therapeutically necessary. Preserve protective measures for independently assessed risks.

This page expands original entry 6, Controlled exposure to an identified trigger. Practical examples and questions are educational adaptations, not patient quotations or a reproduced treatment protocol.
Neurosymptoms offers facial-specific expert guidance on movement/light triggers. It is not a controlled exposure trial. The consent, pacing and environmental examples here are cautious educational adaptations; neither a numeric progression nor a requirement to provoke symptoms is evidence-based for all functional facial presentations.
