Subjects were tested in static (stable support) and dynamic (sinusoidal translation of the support) conditions, both at floor level and at height (62 cm above the floor), and with and without vision, to create an additional postural threat. Wavelet analysis of the center of foot pressure displacement and motion analysis of the body segments were used to evaluate the postural performance. Evaluation questionnaires were used to examine the compensation level of the patients (DHI test), their general anxiety level (SAST), fear of height (subjective scale), and workload (NASA TLX test). (Vestibular loss patients rely more on vision and spend more energy maintaining balance than controls, but they use the same postural strategy as normals in both static and dynamic conditions.) Questionnaire data all showed differences in behavior and perceptions between the controls and the patients. However, at height and without vision, a whole body strategy leading to rigid posture replaces the head stabilization strategy found for standing at floor level. The effects of height on postural control can be attributable to an increase in postural threat and attention changes resulting from modifications in perception.<\/jats:p>","DOI":"10.3233\/ves-2012-0449","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T18:00:08Z","timestamp":1575309608000},"page":"129-138","source":"Crossref","is-referenced-by-count":28,"title":["Postural performance of vestibular loss patients under increased postural threat1"],"prefix":"10.1177","volume":"22","author":[{"given":"Laurence R.","family":"Young","sequence":"first","affiliation":[{"name":"Man-Vehicle Laboratory, Massachusetts Institute of Technology, Cambridge, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurence","family":"Bernard-Demanze","sequence":"additional","affiliation":[{"name":"CNRS\/Aix-Marseille Universit\u00e9, UMR 6149 Neurosciences Int\u00e9gratives et Adaptatives, Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel","family":"Dumitrescu","sequence":"additional","affiliation":[{"name":"CNRS\/Aix-Marseille Universit\u00e9, UMR 6149 Neurosciences Int\u00e9gratives et Adaptatives, Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Magnan","sequence":"additional","affiliation":[{"name":"Service ORL et Chirurgie Cervico-Faciale, H\u00f4pital Nord, Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liliane","family":"Borel","sequence":"additional","affiliation":[{"name":"CNRS\/Aix-Marseille Universit\u00e9, UMR 6149 Neurosciences Int\u00e9gratives et Adaptatives, Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel","family":"Lacour","sequence":"additional","affiliation":[{"name":"CNRS\/Aix-Marseille Universit\u00e9, UMR 6149 Neurosciences Int\u00e9gratives et Adaptatives, Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","container-title":["Journal of Vestibular Research"],"original-title":[],"link":[{"URL":"https:\/\/content.iospress.com\/download?id=10.3233\/VES-2012-0449","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T05:26:10Z","timestamp":1777613170000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/full\/10.3233\/VES-2012-0449"}},"subtitle":[],"editor":[{"given":"Charles M.","family":"Oman","sequence":"additional","affiliation":[{"name":"Man Vehicle Laboratory, Massachusetts Institute of Technology, Cambridge, MA, USA"}],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2012,9,10]]},"references-count":0,"journal-issue":{"issue":"2-3"},"URL":"https:\/\/doi.org\/10.3233\/ves-2012-0449","relation":{"is-cited-by":[{"id-type":"doi","id":"10.3389\/fneur.2018.00789","asserted-by":"object"}]},"ISSN":["1878-6464","0957-4271"],"issn-type":[{"value":"1878-6464","type":"electronic"},{"value":"0957-4271","type":"print"}],"subject":[],"published":{"date-parts":[[2012,9,10]]}}}
