BACKGROUND AND PURPOSE Treatment options for stroke-related dysphagia are currently limited. In this study, we investigated whether noninvasive brain stimulation in combination with swallowing maneuvers facilitates swallowing recovery in dysphagic stroke patients during early stroke convalescence. METHODS Fourteen patients with subacute unilateral(More)
BACKGROUND AND PURPOSE Despite being the gold standard technique for stroke assessment, conventional diffusion MRI provides only partial information about tissue microstructure. Diffusional kurtosis imaging is an advanced diffusion MRI method that yields, in addition to conventional diffusion information, the diffusional kurtosis, which may help improve(More)
OBJECTIVE The aim of this work was to investigate whether an imaging measure of corticospinal tract (CST) injury in the acute phase can predict motor outcome at 3 months in comparison to clinical assessment of initial motor impairment. METHODS A two-site prospective cohort study followed up a group of first-ever ischemic stroke patients using the(More)
BACKGROUND AND PURPOSE Racial disparities among US stroke patients have been well documented. However, the extent to which disparities in outcomes vary by age is unclear. This study's goals were to examine the degree of racial disparities in South Carolina between African Americans (AAs) and Caucasian Americans (CAs) in stroke admission rates, hospital(More)
In observational studies, investigators usually do not have the same control over the treatment assignment as they do with randomized controlled studies. As a result, the treatment and control groups may have a large difference on their observed covariates. These differences could lead to bias in estimating treatment effects. There are several propensity(More)
BACKGROUND Evidence supports peroneal nerve functional electrical stimulation (FES) as an effective alternative to ankle foot orthoses (AFO) for treatment of foot drop poststroke, but few long-term, randomized controlled comparisons exist. OBJECTIVE Compare changes in gait quality and function between FES and AFOs in individuals with foot drop poststroke(More)
OBJECTIVE This study examines the risk of recurrent stroke, myocardial infarction (MI), vascular death, or all-cause death after hospitalized stroke in South Carolina. METHODS Patients with a primary diagnosis of stroke discharged from the year 2002 were identified from the state hospital discharge database. Kaplan-Meier estimates of recurrent stroke, MI,(More)
BACKGROUND Evidence supports peroneal nerve functional electrical stimulation (FES) as an effective alternative to ankle-foot orthoses (AFO) for treatment of foot drop poststroke, but few randomized controlled comparisons exist. OBJECTIVE To compare changes in gait and quality of life (QoL) between FES and an AFO in individuals with foot drop poststroke.(More)
BACKGROUND AND PURPOSE Mounting evidence points to a decline in stroke incidence. However, little is known about recent patterns of stroke hospitalization within the buckle of the stroke belt. This study aims to investigate the age- and race-specific secular trends in stroke hospitalization rates, inpatient stroke mortality rates, and related(More)
Ischemic infarcts and hemorrhages are uncommon but dangerous complications of pregnancy. Their etiology is related to physiological changes during pregnancy. The majority of strokes are seen in the third trimester and postpartum and are etiologically related to three conditions: reversible cerebral vasoconstriction syndrome, preeclampsia/eclampsia and(More)
