Objectives: We previously reported that swallowing in the bridge position (bridge swallowing) increased distal esophageal contractions and lower esophageal sphincter pressure against gravity. Moreover, bridge swallowing had the potential to strengthen esophageal peristalsis. In this study, we sought to evaluate whether the bridge swallowing exercise could improve gastroesophageal reflux disease (GERD) symptoms and gastroscopy findings.
Methods: Seventeen subjects with scores of 8 points or higher on the Frequency Scale for Symptoms of GERD (FSSG) questionnaire participated in the study. The exercise of dry swallowing in the bridge posture lasted 4 weeks and was performed ten times per day. FSSG scores were compared before and after exercise. Three of the 17 participants underwent upper gastrointestinal endoscopy. The modified Los Angeles classification of reflux esophagitis was used for objective assessment before and after exercise.
Results: No participants dropped out of this study. FSSG scores improved significantly after exercise (from median [range] 16 [13–21] points before exercise to 5 [4–10] points after exercise, P <0.001). Upper gastrointestinal endoscopy showed improvement in the modified Los Angeles classification grade in one participant.
Conclusions: The bridge swallowing exercise significantly improves FSSG scores. This exercise can be performed easily and safely without adverse events. Further multicenter prospective studies are needed to validate that the bridge swallowing exercise is effective in improving GERD.
