Immediate Effects of the Forehead Exercise for Suprahyoid Muscles: A Case Series.

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
Introduction Dysphagia is common in older adults and individuals with neurological disorders and is often associated with aspiration pneumonia and reduced quality of life. The Forehead Exercise for Suprahyoid Muscles (FESM, also known as Enge-Odeko-Taiso) is a simple, non-invasive technique aimed at strengthening the suprahyoid muscles. However, its immediate effect on swallowing function is not well understood. We aimed to determine whether a single session of FESM, performed during a videofluoroscopic swallowing study (VFSS), could immediately reduce the risk of penetration and aspiration, as measured by the Penetration-Aspiration Scale (PAS). Methods This small retrospective case series included 12 patients (mean age 76.6 ± 11.3 years) who underwent VFSS at Hamamatsu City Rehabilitation Hospital between December 1, 2024, and April 1, 2025. Patients were included if they had a baseline PAS score ≥2 and performed the FESM during the same VFSS session. Patients performed at least five repetitions of the FESM, which involved isometric chin-tuck contractions, immediately before the post-intervention swallow. Body position, bolus type, and imaging parameters were kept consistent before and after the exercise. Pre- and post-FESM PAS scores were compared using the Wilcoxon signed-rank test (significance set at p < 0.05). Results The median PAS score significantly decreased from 3.5 (interquartile range (IQR), 2.75-8.00) to 1.0 (IQR, 1.00-2.25) following FESM (p = 0.025). Among the 12 patients, 10 showed improvement, one showed no change, and one worsened. Conclusion A single FESM session performed immediately prior to swallowing significantly reduced penetration and aspiration events. These findings suggest that FESM may be a practical, low-effort preparatory exercise to reduce the risk of airway invasion during swallowing. Further controlled trials are needed to confirm these effects and to investigate potential dose-response relationships and long-term benefits.
