Clinical Scales and Wearable Sensors in Patients with Essential Tremor Treated with Deep Brain Stimulation.
Article in Movement disorders clinical practice, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDeep brain stimulation (DBS) for essential tremor (ET) is commonly evaluated using tremor scales, which capture only snapshot of symptoms and miss daily variability. Wearable sensors enable objective monitoring and may offer complementary information to support clinical decisions.
objectivesTo investigate whether continuous wearable monitoring provides additional information to traditional analysis in ET.
methodsForty-five patients with ET undergoing DBS were assessed preoperatively and 9-12 months postoperatively using TETRAS scale, the EQ-5D-3L, and the Personal KinetiGraph (PKG) which quantified percentage time with tremor (PTT). Pre- and postoperative measures were compared and correlated.
resultsDBS significantly improved outcomes: median TETRAS scores decreased by 55% and PKG PTT by 59%. Individual responses varied, and TETRAS and PTT showed week correlation, indicating that instruments capture different aspects of the disorder.
conclusionsCombining clinical scales with wearable monitoring complements traditional assessments by capturing daily tremor fluctuations and supporting optimized DBS management.
