NCT ID: NCT05256563 Active, not recruiting - Stroke Clinical Trials

A Biomarker for Personalized Care in Post-Stroke Spatial Neglect

Start date: September 1, 2021
Phase:
Study type: Observational

More than 30,000 Veterans are hospitalized for stroke each year, and in the critical first months of recovery, at least half are disabled by abnormal 3-D spatial function (spatial neglect). Their self-care, mobility, and ability to return home are severely limited.

NCT ID: NCT00990353 Active, not recruiting - Hemispatial Neglect Clinical Trials

A Model to Identify Specific Predictors of Spatial Neglect Recovery

Start date: January 2009
Phase:
Study type: Observational

This study examines methods to better predict improvement of a hidden disability of functional vision, spatial neglect, following stroke. Spatial neglect is a tendency to make visual judgment and movement errors mislocating the body and objects in space. The investigators are using specialized statistical methods to compute the proportion of improvement accounted for by personal characteristics of each stroke survivor, the proportion of improvement accounted for by the unique visual-spatial errors made by each subject, and the proportion of improvement accounted for by each treatment administered. The investigators will also examine whether brain imaging predicts how rapidly improvement occurs. Lastly, the study tests whether improvements that are meaningful to the survivor can be measured in a way that still allows detection of small and scientifically eloquent performance changes.

NCT ID: NCT00989430 Active, not recruiting - Spatial Neglect Clinical Trials

Prism Adaptation Therapy for Spatial Neglect

Start date: October 2012
Phase: N/A
Study type: Interventional

The purpose of this research study with a randomized controlled design is to examine the effects of prism adaptation treatment on two visual-spatial recovery components. After a stroke, an "internal GPS", locating where objects or people lie in a particular area of space, may be impaired. Alternately, a stroke may impair precise visual-spatial hand and body aiming movements. The research team wishes to discover whether prism adaptation treatment (two weeks of daily 20-min sessions of goal-directed movement with prism goggles) affects visual-spatial where or aiming errors selectively after stroke. This research represents one of the first attempts to apply what we know about the brain from neuroscience research, to modern clinical rehabilitation practices.

NCT ID: NCT00350012 Active, not recruiting - Stroke Clinical Trials

Spatial Neglect and Bias in Near and Far Space

Start date: May 2004
Phase:
Study type: Observational

The purpose of this research study is to learn how people distribute their visual attention when looking at objects nearby versus far away, and why vision may become distracted at near versus far distances.
