Ultrasound-guided repetitive pulsed peripheral magnetic stimulation provides pain relief in refractory glossopharyngeal neuralgia: 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
Aims: Repetitive peripheral magnetic stimulation (rPMS) is a novel nonpharmacological treatment modality. This noninvasive approach can stimulate peripheral nerves to provide analgesia through neuromodulation. We report the first case of ultrasound-guided rPMS to treat a case of severe refractory glossopharyngeal neuralgia. Methods: A 70-year-old female with an 8-year history of glossopharyngeal neuralgia reported refractory pain unresponsive to pharmacological and interventional treatments. After consenting to treatment, the patient received high-frequency rPMS in three different sessions using intermittent theta burst stimulation below motor thresholds. rPMS was applied over the skin directed at the glossopharyngeal nerve identified using ultrasound guidance. Session 1 included 20 min of continuous treatment, session 2 included 40 min of treatment (two 20-min treatments separated by a 10-min break), session 3 included 40 min of treatment (similar to Session 2) repeated daily for 5 days. Pre- and postintervention pain levels were collected with a daily 1-week pain diary and pain questionnaires. Results: Session 1 led to an immediate 30% decrease in pain after treatment. Session 2 led to a 75% decrease in pain immediately after treatment that remained reduced for approximately 2 days. Session 3 produced complete pain relief immediately after treatment and remained lower for 5 days after treatment and returned to baseline levels at 1 week. Conclusion: rPMS provided immense but temporary relief in a severe case of refractory glossopharyngeal neuralgia. Further work is needed to determine the most effective regimen to treat complex pain disorders in the head and neck.
