Negative oral pressure during rest and pressure changes during swallowing were measured in a space between the palate and tongue (<jats:styled-content style=\"fixed-case\">STP<\/jats:styled-content>). Twenty volunteers were asked to sit in a chair in a relaxed upright position. A sensor was placed on the posterior midline of hard palate. Recording commenced just before subjects closed their lips and continued. Subjects were asked to swallow saliva and keep the apposition. Finally, subjects were asked to open their mouth. Recordings were performed five times, and 5 s of continuous data in each phase was averaged. To verify the reliability of the system, the same procedure was accomplished with twin sensors. When the jaw and lips were closed, the pressure slightly decreased from atmospheric pressure (\u22120\u00b717 \u00b1 0\u00b724\u2010<jats:styled-content style=\"fixed-case\">kP<\/jats:styled-content>a). After swallowing, the pressure in <jats:styled-content style=\"fixed-case\">STP<\/jats:styled-content> showed more negative value (\u22120\u00b750 \u00b1 0\u00b759\u2010<jats:styled-content style=\"fixed-case\">kP<\/jats:styled-content>a). There is a significant difference between the values in open condition and after swallowing (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001) and between values after swallowing and final open condition (<jats:italic>P<\/jats:italic> &lt; 0\u00b705). Twin sensor showed almost the same trajectories of pressure changes for all the recordings. Obtained negative pressure might generate about 0\u00b771\u2010N of force and would be enough to keep the tongue in the palatal fossa at rest. The system detected large negative\/positive pressure changes during swallowing. We conclude this system may be a tool to evaluate oral functions.<\/jats:p>","DOI":"10.1111\/joor.12456","type":"journal-article","created":{"date-parts":[[2016,11,16]],"date-time":"2016-11-16T15:04:18Z","timestamp":1479308658000},"page":"65-72","source":"Crossref","is-referenced-by-count":15,"title":["Application of a barometer for assessment of oral functions: Donders space"],"prefix":"10.1111","volume":"44","author":[{"given":"K.","family":"Hiraki","sequence":"first","affiliation":[{"name":"Department of Oral Health and Clinical Science Division of Dysphagia Rehabilitation Tokyo Dental College Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.","family":"Yamada","sequence":"additional","affiliation":[{"name":"Oral Health Science Center Tokyo Dental College Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Kurose","sequence":"additional","affiliation":[{"name":"Division of Oral Physiology Niigata University Graduate School of Medical and Dental Sciences Niigata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.","family":"Ofusa","sequence":"additional","affiliation":[{"name":"Department of Geriatric Dentistry Tsurumi University School of Dental Medicine Yokohama Japan"},{"name":"Department of Physiology Tokyo Dental College Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Sugiyama","sequence":"additional","affiliation":[{"name":"Department of Oral Health and Clinical Science Division of Dysphagia Rehabilitation Tokyo Dental College Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Ishida","sequence":"additional","affiliation":[{"name":"Department of Oral Health and Clinical Science Division of Dysphagia Rehabilitation Tokyo Dental College Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,11,30]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-food-030212-182637"},{"key":"e_1_2_9_3_1","first-page":"371","article-title":"Swallowing, ingestion and dysphagia: a reappraisal","volume":"64","author":"Leopold NA","year":"1983","journal-title":"Arch Phys Med Rehabil"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-007-9126-z"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-004-0010-9"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.physbeh.2006.09.032"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.physbeh.2006.01.025"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-009-0367-0"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-012-0897-8"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1159\/000392723"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01639926"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.archoralbio.2006.12.017"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.humov.2004.08.010"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1067\/mod.2001.119802"},{"key":"e_1_2_9_15_1","first-page":"214","article-title":"Negative oral pressures.
