This study aimed to identify the effect of three different body positions on esophageal motility using high-resolution manometry. Thirteen healthy adults swallowed 5\u00a0mL of water in the upright, supine, and bridge positions. For the bridge position, each subject raised their waist against gravity, placed a cushion under their back, and bent their knees. The proximal contractile integral (PCI) and distal contractile integral (DCI), integrated relaxation pressure (IRP), distal latency (DL), peristaltic breaks (PBs), intrabolus pressure (IBP), and expiratory and inspiratory esophagoesophageal junction (EGJ) pressure were measured. In the bridge position, PCI, DCI, IRP, and expiratory and inspiratory EGJ pressure were significantly higher than those in the upright position (bridge PCI vs. upright PCI [<jats:italic>p<\/jats:italic>\u2009=\u20090.001], bridge DCI vs. upright DCI [<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001], bridge IRP vs. upright IRP [<jats:italic>p<\/jats:italic>\u2009=\u20090.018], bridge EGJ pressure vs. upright EGJ pressure [expiratory: <jats:italic>p<\/jats:italic>\u2009=\u20090.001] [inspiratory: <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001]). PBs were significantly shorter and DL was significantly longer in the bridge position compared to upright (bridge PBs vs. upright PBs [<jats:italic>p<\/jats:italic>\u2009=\u20090.001], bridge DL vs. upright DL [<jats:italic>p<\/jats:italic>\u2009=\u20090.001]). IBP was significantly higher in the bridge position compared to supine (bridge IBP vs. supine IBP [<jats:italic>p<\/jats:italic>\u2009=\u20090.01]). These results demonstrated changes in esophageal motility according to changes in position while swallowing, where esophageal contractions became stronger against gravity. Further study is required to examine the effectiveness of swallowing in the bridge position.<\/jats:p>","DOI":"10.1007\/s00455-020-10169-0","type":"journal-article","created":{"date-parts":[[2020,8,4]],"date-time":"2020-08-04T10:02:57Z","timestamp":1596535377000},"page":"551-557","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effect of Bridge Position Swallow on Esophageal Motility in Healthy Individuals Using High-Resolution Manometry"],"prefix":"10.1007","volume":"36","author":[{"given":"Kei","family":"Aoyama","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenjiro","family":"Kunieda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Shigematsu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohisa","family":"Ohno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ichiro","family":"Fujishima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,8,4]]},"reference":[{"key":"10169_CR1","doi-asserted-by":"publisher","first-page":"953","DOI":"10.2214\/ajr.154.5.2108569","volume":"154","author":"WJ Dodds","year":"1990","unstructured":"Dodds WJ, Stewart ET, Logemann JA.
