Yet little knowledge is available regarding whether these deviations will produce nonpathological changes to the clinical results obtained. The present\n study aimed to describe the effects of body position on the distortion-product otoacoustic emissions of 60 normal-hearing adults. With particular attention given to common clinical practice, the Otodynamics ILO292, and the measurement parameters of amplitude, signal-to-noise ratio, and noise\n were utilized. Significant position-related effects and interactions were revealed for all parameters. Specifically, stronger emissions in the mid frequencies and higher noise levels at the extreme low and high frequencies were produced by testing subjects while lying on their side compared\n with the seated position. Further analysis of body position effects on emissions is warranted, in order to determine the need for clinical application of position-dependent normative data. Las emisiones otoac\u00fasticas se obtienen frecuentemente con los pacientes colocados en una variedad\n de posiciones, adem\u00e1s de la posici\u00f3n convencional de sedestaci\u00f3n. Sin embargo, existe poco conocimiento disponible sobre si estas desviaciones producen cambios no patol\u00f3gicos en los resultados cl\u00ednicos obtenidos. El presente estudio busc\u00f3 describir,\n en 60 adultos normo-oyentes, los efectos de la posici\u00f3n del cuerpo en las emisiones otoac\u00fasticas por productos de distorsi\u00f3n. Se utiliz\u00f3 un equipo Otodynamics ILO292, adem\u00e1s de los par\u00e1metros de amplitud, tasa de se\u00f1al-ruido y ruido, respetando\n los criterios comunes usados en la pr\u00e1ctica cl\u00ednica. Se revelaron efectos e interacciones significativas relacionadas con la posici\u00f3n para todos los par\u00e1metros. Espec\u00edficamente, se produjeron emisiones m\u00e1s fuertes en las frecuencias medias y niveles\n m\u00e1s altos de ruido en las frecuencias graves y agudas, cuando se evalu\u00f3 a los sujetos acostados en posici\u00f3n lateral, y los resultados se compararon con aquellos en posici\u00f3n sentada. Se necesita an\u00e1lisis adicional de los efectos de la posici\u00f3n del cuerpo\n sobre las emisiones, para determinar la necesidad de aplicaciones cl\u00ednicas de los datos normativos dependientes de la posici\u00f3n.<\/jats:p>","DOI":"10.3766\/jaaa.15.8.4","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T23:54:28Z","timestamp":1208908468000},"page":"566-573","source":"Crossref","is-referenced-by-count":4,"title":["The Effects of Body Position on Distortion-Product Otoacoustic Emission Testing"],"prefix":"10.3766","volume":"15","author":[{"given":"Carlie","family":"Driscoll","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Kei","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jenny","family":"Shyu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natasha","family":"Fukai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2087","container-title":["Journal of the American Academy of Audiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/aaa\/jaaa\/2004\/00000015\/00000008\/art00004","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T23:10:03Z","timestamp":1738797003000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.15.8.4"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,9,1]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2004,9,1]]}},"alternative-id":["1050-0545(20040901)15:8L.566;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.15.8.4","relation":{},"ISSN":["1050-0545"],"issn-type":[{"type":"print","value":"1050-0545"}],"subject":[],"published":{"date-parts":[[2004,9,1]]}}}
