Forty\u2010nine patients with complaints of swallow difficulty received a videofluorographic (<jats:styled-content style=\"fixed-case\">VF<\/jats:styled-content>) examination. They were divided into three groups: nine who did not have any apparent disease (<jats:styled-content style=\"fixed-case\">G<\/jats:styled-content>roup <jats:styled-content style=\"fixed-case\">N<\/jats:styled-content>), 22 patients with head and neck cancer (<jats:styled-content style=\"fixed-case\">G<\/jats:styled-content>roup <jats:styled-content style=\"fixed-case\">H&amp;N<\/jats:styled-content>) and 18 patients with other diseases including cerebrovascular disease (<jats:styled-content style=\"fixed-case\">G<\/jats:styled-content>roup <jats:styled-content style=\"fixed-case\">OD<\/jats:styled-content>). After liquid barium swallows, they exhaled voluntarily without voicing. Videofluorographic findings were classified into four groups: normal (<jats:styled-content style=\"fixed-case\">N<\/jats:styled-content>ormal), acceptable swallow (Acceptable), swallow with residue (Resid) and swallows with penetration or aspiration (Pen\/Asp). The duration of expiratory sounds was measured on the time waveform. Frequency characteristics of expiratory sounds were obtained using one\u2010third octave band analysis ranging from 62\u00b75 to 2000\u00b70\u00a0Hz of central frequency. The averaged level of the 1000\u00b70\u2010Hz band was chosen as the reference band level (<jats:styled-content style=\"fixed-case\">RB<\/jats:styled-content> level). The revised averaged level of each band was obtained by subtracting the <jats:styled-content style=\"fixed-case\">RB<\/jats:styled-content> level from the averaged level of each band. Zero decibel of the revised magnitude of the 125\u00b70\u2010Hz band was set as the critical value to differentiate dysphagia (<jats:styled-content style=\"fixed-case\">R<\/jats:styled-content>esid or Pen\/Asp) from no dysphagia (<jats:styled-content style=\"fixed-case\">N<\/jats:styled-content>ormal or <jats:styled-content style=\"fixed-case\">A<\/jats:styled-content>cceptable). Comparison of this assessment with <jats:styled-content style=\"fixed-case\">VF<\/jats:styled-content> findings showed a significant percentage agreement (85\u00b74%). These results suggest that frequency characteristics of post\u2010swallow expiratory sounds can differentiate dysphagia from no dysphagia among multiple dysphagic patient groups.<\/jats:p>","DOI":"10.1111\/joor.12184","type":"journal-article","created":{"date-parts":[[2014,5,20]],"date-time":"2014-05-20T04:59:01Z","timestamp":1400561941000},"page":"667-674","source":"Crossref","is-referenced-by-count":13,"title":["Acoustic characteristics of voluntary expiratory sounds after swallow for detecting dysphagia"],"prefix":"10.1111","volume":"41","author":[{"given":"M.","family":"Yamashita","sequence":"first","affiliation":[{"name":"Division of Oral Rehabilitation Medicine Department of Special Needs Dentistry Showa University School of Dentistry Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Yokoyama","sequence":"additional","affiliation":[{"name":"Division of Oral Rehabilitation Medicine Department of Special Needs Dentistry Showa University School of Dentistry Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Takei","sequence":"additional","affiliation":[{"name":"Division of Oral Rehabilitation Medicine Department of Special Needs Dentistry Showa University School of Dentistry Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Furuya","sequence":"additional","affiliation":[{"name":"Division of Oral Rehabilitation Medicine Department of Special Needs Dentistry Showa University School of Dentistry Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Nakamichi","sequence":"additional","affiliation":[{"name":"Division of Oral Rehabilitation Medicine Department of Special Needs Dentistry Showa University School of Dentistry Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Ihara","sequence":"additional","affiliation":[{"name":"Division of Oral Rehabilitation Medicine Department of Special Needs Dentistry Showa University School of Dentistry Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Division of Oral Rehabilitation Medicine Department of Special Needs Dentistry Showa University School of Dentistry Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
