BACKGROUND & AIMS The aim of this study was to determine the mechanism for recovery of swallowing after dysphagic stroke. METHODS Twenty-eight patients who had a unilateral hemispheric stroke were studied 1 week and 1 and 3 months after the stroke by videofluoroscopy. Pharyngeal and thenar electromyographic responses to magnetic stimulation of multiple(More)
Because no detailed information exists regarding the topographic representation of swallowing musculature on the human cerebral cortex in health or disease, we used transcranial magnetic stimulation to study the cortical topography of human oral, pharyngeal and esophageal musculature in 20 healthy individuals and the topography of pharyngeal musculature in(More)
BACKGROUND AND PURPOSE We sought to determine the frequency of occurrence of contralesional unilateral spatial neglect (USN) after stroke and to investigate the effect of side of lesion, nature of assessment tool used, and timing of assessment relative to stroke onset. METHODS We performed a systematic review of published reports, identified by a search(More)
BACKGROUND Oropharyngeal dysphagia occurs in up to a third of patients presenting with a unilateral hemiplegic stroke, yet its neurophysiological basis remains unknown. To explore the relation between cortical motor function of swallowing and oropharyngeal dysphagia, mylohyoid, pharyngeal, and thenar electromyographic responses to stimulation of affected(More)
BACKGROUND There are no data on prevalence or incidence of treated epilepsy, and no data on fertility of women with epilepsy from an unselected UK population. METHODS We used the General Practice Research Database to ascertain the incidence and prevalence of people with treated epilepsy in an unselected population of 2,052,922 people in England and Wales,(More)
BACKGROUND AND PURPOSE Balance disability is common after stroke, but there is little detailed information about it. The aims of this study were to investigate the frequency of balance disability; to characterize different levels of disability; and to identify demographics, stroke pathology factors, and impairments associated with balance disability.

OBJECTIVE To explore the efficacy of repetitive transcranial magnetic stimulation (rTMS) and voluntary muscle contraction (VMC) to improve corticospinal transmission, muscle function, and purposeful movement early after stroke. METHODS Factorial 2 x 2 randomized single-blind trial. SUBJECTS n = 27, mean age 75 years, mean 27 days after middle cerebral(More)
BACKGROUND Therapists and nurses often use verbal instruction in the rehabilitation of mobility following stroke. This study aimed to determine whether performing a verbal cognitive task while walking adversely affected patients' balance and velocity. METHODS There were two counterbalanced conditions: walking only and walking and concurrent cognitive(More)
BACKGROUND Functional training and muscle strength training may improve upper limb motor recovery after stroke. Combining these as functional strength training (FST) might enhance the benefit, but it is unclear whether this is better than conventional physical therapy (CPT). Comparing FST with CPT is not straightforward. OBJECTIVE This study aimed at(More)
OBJECTIVE To characterize the nature of sensory impairments after stroke, identify associated factors, and assess the relationships between sensory impairment, disability, and recovery. METHODS Prospective cross-sectional survey of 102 people with hemiparesis following their first stroke. Tactile and proprioceptive sensation in the affected arm and leg(More)
