R\u00e9sum\u00e9 :<\/h2>\n\n

Des r\u00e9sultats ant\u00e9rieurs d’imagerie par r\u00e9sonance magn\u00e9tique fonctionnelle (IRMf) indiquent que l’appr\u00e9hension de l’\u00e9paule est plus complexe qu’un simple probl\u00e8me m\u00e9canique de l’\u00e9paule, montrant une modification directe des r\u00e9seaux c\u00e9r\u00e9braux fonctionnels associ\u00e9s \u00e0 l’inhibition motrice et \u00e0 la r\u00e9gulation \u00e9motionnelle. L’\u00e9tude actuelle prolonge ces r\u00e9sultats en examinant d’autres alt\u00e9rations structurelles chez les patients souffrant d’appr\u00e9hension de l’\u00e9paule par rapport aux t\u00e9moins. 14 patients \u00e2g\u00e9s (27,3 \u00b1 2,0 ans) souffrant d’appr\u00e9hension de l’\u00e9paule et 10 t\u00e9moins sains appari\u00e9s (29,6 \u00b1 1,3 ans) ont subi un examen clinique et un examen IRMf comprenant l’IRMf et l’imagerie du tenseur de diffusion (DTI). La proc\u00e9dure statistique spatiale bas\u00e9e sur les trac\u00e9s a \u00e9t\u00e9 utilis\u00e9e pour analyser les alt\u00e9rations de la mati\u00e8re blanche (MW). Les images fonctionnelles ont \u00e9t\u00e9 analys\u00e9es pour \u00e9tudier la connectivit\u00e9 du r\u00e9seau \u00e0 l’\u00e9tat de repos. Les r\u00e9sultats de l’ITD ont \u00e9t\u00e9 corr\u00e9l\u00e9s avec les diff\u00e9rents scores cliniques de l’\u00e9paule et les r\u00e9seaux de connectivit\u00e9 fonctionnelle. L’anisotropie fractionnelle (AF), qui repr\u00e9sente l’int\u00e9grit\u00e9 de la mati\u00e8re blanche, est augment\u00e9e dans la capsule interne gauche et partiellement dans le thalamus chez les patients par rapport aux t\u00e9moins. En outre, l’AF est en corr\u00e9lation n\u00e9gative avec les r\u00e9sultats du test de l’\u00e9paule simple (SST) (p < 0,05) et positive avec un r\u00e9seau de connectivit\u00e9 fonctionnelle reproduisant qualitativement les r\u00e9sultats pr\u00e9c\u00e9dents (p < 0,01). Cette \u00e9tude \u00e9largit les r\u00e9sultats pr\u00e9c\u00e9dents en montrant qu’en plus des changements fonctionnels, des changements structurels de la mati\u00e8re blanche sont \u00e9galement pr\u00e9sents chez les patients souffrant d’appr\u00e9hension de l’\u00e9paule. <\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"publication_categories":[151],"class_list":["post-11608","publications","type-publications","status-publish","hentry","publication_categories-publications-scientifiques"],"acf":[],"yoast_head":"\nStructural white matter alterations in patients with shoulder apprehension. -
