Abstract
To investigate how prehensile movements, such as reaching and grasping, are affected by different fields of view when both haptic and visual information are available.

Subjects picked up an object with a full monocular field of view (FOV) and with two different sizes of pinholes which simulated a central FOV of 23 degrees and 11 degrees respectively. The Vicon motion analysis system was used to record and reconstruct the 3D-kinematic data. The kinematic parameters measured were total time of the movement, maximum velocity, time to maximum velocity, deceleration time, maximum grip aperture, time to maximum grip aperture and time taken after maximum grip aperture.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">Restricting the FOV affected both the transport and grasp components of the movement. The maximum velocity decreased (p = 0.008) and the maximum grip aperture increased (p = 0.003) with both restricted FOV when compared with the full field. The execution or on-line control of both reach and grasp components were also longer (p = 0.005 and p = 0.002 respectively) for the 11 degrees FOV only.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Reducing the FOV to 11 degrees (an absence of peripheral vision) affects the planning and execution of the reach and the grasp component of the movement. Restricting the FOV to 23 degrees of central vision (with some peripheral cues present) affects only the planning of the reach and grasp component of the movement. Peripheral visual cues are therefore more important for the on-line control than for the planning of the movement. The findings of this study have important clinical implications in patients who suffer from ocular diseases in which peripheral vision gradually decreases.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>González-Alvarez</LastName><ForeName>Carmen</ForeName><Initials>C</Initials><AffiliationInfo><Affiliation>Department of Optometry and Ophthalmic Dispensing, Anglia Ruskin University, Cambridge, UK. c.gonzalez@anglia.ac.uk</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Subramanian</LastName><ForeName>Ahalya</ForeName><Initials>A</Initials></Author><Author ValidYN="Y"><LastName>Pardhan</LastName><ForeName>Shahina</ForeName><Initials>S</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>England</Country><MedlineTA>Ophthalmic Physiol Opt</MedlineTA><NlmUniqueID>8208839</NlmUniqueID><ISSNLinking>0275-5408</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000328">Adult</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D004215">Distance Perception</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D005260">Female</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D018737">Hand Strength</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D008297">Male</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D008954">Models, Biological</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D009068">Movement</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D011597">Psychomotor Performance</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014794">Visual Fields</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014796">Visual Perception</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000502">physiology</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2007</Year><Month>5</Month><Day>2</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2007</Year><Month>8</Month><Day>19</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2007</Year><Month>5</Month><Day>2</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pii">OPO476</ArticleId><ArticleId IdType="doi">10.1111/j.1475-1313.2007.00476.x</ArticleId><ArticleId IdType="pubmed">17470239</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
