Hypnosis as a Non-Pharmacologic Adjunct in Magnetic Resonance-Guided Focused Ultrasound Thalamotomy for Essential Tremor: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND Transcranial magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy has become an established and effective therapeutic option for patients with essential tremor (ET) who do not adequately respond to medication. Although generally safe and minimally invasive, this procedure is lengthy and highly interactive; it requires patients to remain awake, cooperative, and motionless for several hours. Intraprocedural side effects (SEs) are relatively common. Reports frequently describe symptoms such as vertigo, scalp burning sensation, nausea, perioral paresthesia, headache, and reduced patient cooperation. Management of these issues usually relies on pharmacologic interventions, including anxiolytics or analgesics, which may interfere with patient responsiveness. Non-pharmacologic strategies have received far less attention. To date, the potential role of hypnosis, either before or during MRgFUS, has not been explored in this context, although it may reduce SEs and promote greater patient comfort. CASE REPORT We describe a 75-year-old woman with longstanding, medication-refractory ET who underwent MRgFUS thalamotomy targeting the ventral intermediate nucleus of the thalamus. Before the intervention, a standardized hypnosis protocol was implemented for both emotional and physical preparation. During frame fixation and pre-procedural stages, guided hypnosis was provided. Patient-directed self-hypnosis was performed during the sonication process. No sedatives or anxiolytics were administered. The patient tolerated the procedure exceptionally well, without complications, interruptions, or pharmacologic support required; she expressed strong satisfaction with the experience. CONCLUSIONS These observations suggest that hypnosis represents a safe, feasible, and effective non-pharmacologic adjunct to MRgFUS thalamotomy, with the potential to reduce intraprocedural SEs and enhance patient cooperation.
