In addition, the study aimed to compare the reliability of the Virtual system with a previously established bucket test of SVV.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Fifteen participants with normal hearing, normal middle ear function, and normal utricular function were included in the study. Each participant underwent static SVV testing using both the Virtual system and the bucket test. Subjects completed 2 testing sessions to determine test\u2013retest reliability. For each test, data were collected with the head at 0\u00b0, tilted 45\u00b0 to the right, and tilted 45\u00b0 to the left.<\/jats:p><\/jats:sec><jats:sec><jats:title>Setting<\/jats:title><jats:p>This study was conducted in a balance function laboratory embedded in a large, tertiary care otology clinic.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean SVV values obtained with the Virtual system were within 1\u00b0\u20132\u00b0 from 0 with the head positioned at 0\u00b0, which is in agreement with many other studies of SVV with the head at 0\u00b0 (Akin &amp; Murnane, 2009; Halmagyi &amp; Curthoys, 1999; Zwergal, Rettinger, Frenzel, Dieterich, &amp; Strupp, 2009). Using the intraclass correlation coefficient, test\u2013retest reliability of the Virtual system was excellent in the 45\u00b0 left position and fair to good in the 45\u00b0 right and 0\u00b0 position. Test\u2013retest reliability of the bucket test was poor in all head positions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The Virtual system is a more reliable measure of static SVV than the bucket test. Therefore, the Virtual system could be utilized as a screening device for utricular dysfunction in busy clinical settings.<\/jats:p><\/jats:sec>","DOI":"10.1044\/2018_aja-17-0019","type":"journal-article","created":{"date-parts":[[2018,6,25]],"date-time":"2018-06-25T19:31:03Z","timestamp":1529955063000},"page":"249-259","source":"Crossref","is-referenced-by-count":39,"title":["Assessment of Subjective Visual Vertical (SVV) Using the \u201cBucket Test\u201d and the Virtual SVV System"],"prefix":"10.1044","volume":"27","author":[{"given":"Patricia L.","family":"Michelson","sequence":"first","affiliation":[{"name":"Division of Vestibular Sciences, Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devin L.","family":"McCaslin","sequence":"additional","affiliation":[{"name":"Vestibular and Balance Laboratory, Department of Otorhinolaryngology, Mayo Clinic, Rochester, MN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary P.","family":"Jacobson","sequence":"additional","affiliation":[{"name":"Division of Vestibular Sciences, Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Petrak","sequence":"additional","affiliation":[{"name":"Interacoustics, Middelfart, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren","family":"English","sequence":"additional","affiliation":[{"name":"Division of Vestibular Sciences, Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelsey","family":"Hatton","sequence":"additional","affiliation":[{"name":"Division of Vestibular Sciences, Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1310","reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0029-1241128"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.3766\/jaaa.22.7.6"},{"key":"e_1_3_2_4_1","unstructured":"American Speech-Language-Hearing Association.
