High-frame-rate ultrasound analysis of gastric peristalsis using the peristaltic analyzer: a pilot feasibility study.
Article in Frontiers in bioengineering and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Gastric peristalsis plays a pivotal role in regulating gastric emptying and digestive function. However, current clinical assessments of gastric motility primarily rely on invasive or low-temporal-resolution techniques, which fail to support dynamic, real-time evaluations. Methods: We innovatively extended the Peristaltic Analyzer (PA)-a high-frame-rate ultrasound technology originally designed for endometrial wave analysis to the assessment of gastric peristalsis. Utilizing submicron displacement tracking and spatiotemporal vector analysis, we conducted real-time visualization and quantitative evaluation of gastric motility in 9 healthy volunteers. Results: All participants completed image acquisition and peristaltic tracking. The detected peristaltic waves consistently propagated from the proximal to the distal stomach, with an average propagation speed of 1.99 ± 0.18 mm/s, propagation distance of 3.23 ± 0.33 cm, peristaltic intensity of 4.76 ± 1.52 (relative units), interval of 17.31 ± 0.86 s, and frequency of 3.53 ± 0.19 bpm. Waveforms appeared continuous and rhythmic, with uniform propagation direction and clear spatiotemporal profiles. Conclusion: As the first application of the PA high-frame-rate peristaltic analysis technology to gastric motility assessment, this study demonstrates its strong potential as a non-invasive and real-time tool for early detection, quantitative monitoring, and clinical evaluation of functional gastrointestinal disorders. PA exhibited superior performance in motion detection, directional analysis, and fine-scale displacement measurement. These capabilities highlight its potential as a novel tool for early identification and longitudinal monitoring of functional gastrointestinal disorders, postoperative gastric dysmotility, and diabetic gastroparesis, offering substantial clinical translational value and applicability.
