Structural and functional alterations in postmenopausal women with insomnia: an MRI study of Eight-Section Vajra Exercise intervention effects.

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: Postmenopausal women exhibit heightened vulnerability to chronic insomnia due to estrogen decline and age-related neural alterations. While non-pharmacological interventions are preferred for long-term management, the neuroplastic mechanisms underlying exercise-based therapies remain poorly characterized. Methods: This study examines the effects of Eight-Section Vajra Exercise (ESVE) on brain structure and function in postmenopausal women with insomnia (PMWI) using multimodal MRI. A 12-week ESVE training program was completed by PMWI patients, followed by clinical assessments (PSQI, ISI, PHQ-9, GAD-7, FSS, MoCA) and neuroimaging (fMRI and structural MRI). Data analysis involved gray matter volume (GMV), ALFF/fALFF, ReHo, degree centrality (DC), and functional connectivity (FC) using advanced MRI processing techniques (CAT12, SPM12, DPABI). Group comparisons and correlations were adjusted for age, education, and intracranial volume. Result: Among the 24 PMWI patients and 30 healthy controls (HCs), baseline measures showed significantly worse sleep and mood scores in PMWI. Resting-state fMRI revealed reduced ALFF/fALFF in the right precentral gyrus and decreased ReHo in sensorimotor areas. Changes in functional connectivity (FC) were noted, with altered connections between precentral gyrus, temporal and parietal regions. After 12 weeks of ESVE, 78.95% of PMWI patients were medication-free, with post-treatment fMRI showing improved neural activity and connectivity, correlating with clinical improvement. Exercise adherence positively correlated with sleep quality improvement ( Conclusion: ESVE alleviates postmenopausal insomnia through PreCG-centered sensorimotor-visual network reorganization, potentially compensating for estrogen-dependent neurocircuitry vulnerabilities. Exercise-induced GMV increases in occipitotemporal regions suggest enhanced sleep-related memory consolidation. Our findings indicate that ESVE is a potential neuromodulatory intervention and identify PreCG-MOG connectivity as a promising biomarker for personalized insomnia management.
