AbstractThe presence of visual dependence as an influential factor on the development of functional stability in ambulatory individuals with cerebral palsy (CP) was studied in 22 adults with spastic bilateral CP, 11 of whom were considered visually dependent, and 18 healthy adults. Participants stood upright during pitch plane disturbances of the visual field and support surface. Intersegmental coordination behaviors were assessed by fitting trajectories of adjacent body segments to an ellipse. Mixed-model repeated measures ANOVAs were performed on ellipse orientation angle and area. Dissimilar stabilizing strategies adopted by the two groups with CP imply that visual dependence impacts postural control. Postural reorganization in response to visual flow in all groups indicates that we cannot ignore perceptual aspects of postural control when designing therapeutic interventions. 相似文献

This study evaluated structural equation models of the associations among family functioning, childhood abuse, depression, anxiety, alexithymia, and eating disorder symptomatology in a sample of 412 European American and 192 African American female undergraduates. Additionally, the specific roles of anxiety, depression, and alexithymia as mediators were assessed. Each of these variables was a significant mediator of the association between childhood abuse and disordered eating. Finally, a test of invariance between the African American and European American subsamples was significant, highlighting the need for additional cross-cultural eating disorder research. 相似文献
