Abstract
We hypothesised that backward disequilibrium (BD), defined by a posterior position of the centre of mass with respect to the base of support, could be caused by a backward tilt in the perception of verticality.

An original ordinal scale, the BD scale (BDS), was used to quantify BD. Postural (PV) and haptic verticals (HV) were measured in sagittal plane.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">BDS scores closely correlated with the number of falls (r = 0.81, p =10(-5)). The more the PV was tilted backward, the greater the BDS scores (r = -0.95, p<10(-6)), with a huge backward tilt of about 15 degrees in 4 subjects with severe BD. In these subjects, the tilt in perception of verticality was transmodal since a severe backward HV tilt was also found.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">This transmodality suggested high-order cognitive disruption in the construction of the subjective vertical used in postural control by subjects showing BD, which confirmed our hypothesis.</AbstractText><AbstractText Label="SIGNIFICANCE" NlmCategory="CONCLUSIONS">This study clearly shows that perception and action with respect to gravity are closely related and brings a new insight about fall mechanisms in the elderly.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Manckoundia</LastName><ForeName>Patrick</ForeName><Initials>P</Initials><AffiliationInfo><Affiliation>INSERM/ERIT-M 0207 Motricité-Plasticité, Université de Bourgogne, Dijon, France. patrick.manckoundia@chu-dijon.fr</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Mourey</LastName><ForeName>France</ForeName><Initials>F</Initials></Author><Author ValidYN="Y"><LastName>Pfitzenmeyer</LastName><ForeName>Pierre</ForeName><Initials>P</Initials></Author><Author ValidYN="Y"><LastName>Van Hoecke</LastName><ForeName>Jacques</ForeName><Initials>J</Initials></Author><Author ValidYN="Y"><LastName>Pérennou</LastName><ForeName>Dominic</ForeName><Initials>D</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D003160">Comparative Study</PublicationType><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2007</Year><Month>02</Month><Day>20</Day></ArticleDate></Article><MedlineJournalInfo><Country>Netherlands</Country><MedlineTA>Clin Neurophysiol</MedlineTA><NlmUniqueID>100883319</NlmUniqueID><ISSNLinking>1388-2457</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000058">Accidental Falls</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000369">Aged, 80 and over</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D015577">Geriatric Assessment</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D010865">Pilot Projects</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D004856">Postural Balance</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D011187">Posture</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D012720">Severity of Illness Index</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D015837">Vestibular Diseases</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000209">etiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014724">Vestibular Function Tests</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014796">Visual Perception</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="received"><Year>2005</Year><Month>12</Month><Day>30</Day></PubMedPubDate><PubMedPubDate PubStatus="revised"><Year>2006</Year><Month>10</Month><Day>20</Day></PubMedPubDate><PubMedPubDate PubStatus="accepted"><Year>2006</Year><Month>11</Month><Day>18</Day></PubMedPubDate><PubMedPubDate PubStatus="aheadofprint"><Year>2007</Year><Month>2</Month><Day>20</Day></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2007</Year><Month>2</Month><Day>23</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2007</Year><Month>5</Month><Day>16</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2007</Year><Month>2</Month><Day>23</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pii">S1388-2457(06)01804-9</ArticleId><ArticleId IdType="doi">10.1016/j.clinph.2006.11.274</ArticleId><ArticleId IdType="pubmed">17314062</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
