Effect of Abdominal Training With Whole-Body Vibration on Erector Spinae Stiffness: A Randomized Trial Using Shear Wave Elastography.

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
Objective: The purpose of this study was to compare the effects of 4 weeks of conventional abdominal training and training combined with whole-body vibration (WBV) on erector spinae (ES) stiffness, assessed using ultrasound shear wave elastography. Methods: Twenty-four healthy university students were randomly assigned to either a WBV or non-WBV group and performed the same exercise on the floor. The participants held a sit-up position for training, 3 times per week for 4 weeks. The primary outcome was ES stiffness measured using shear wave elastography. Secondary outcomes included pressure pain threshold of the ES, lumbar proprioception, and maximum lumbar flexion angle. Split-plot ANOVA was used to analyze the data. Results: There was no significant group × period interaction for ES stiffness. However, the WBV group showed a significant reduction in ES stiffness and an improvement in lumbar proprioception after the intervention. In contrast, the non-WBV group showed a decrease in ES pressure pain threshold. Conclusion: Abdominal training with WBV reduced ES stiffness and enhanced lumbar proprioception in asymptomatic adults. These findings suggest that WBV may improve trunk muscle properties and sensorimotor function.
