BACKGROUND/PURPOSE The Baltimore-Washington Cooperative Young Stroke Study is the largest biracial urban-suburban population-based study to examine the etiology of strokes in children. METHODS We identified all children aged 1 to 14 years discharged from all 46 hospitals in central Maryland and Washington, DC with a diagnosis of ischemic stroke and(More)
BACKGROUND AND PURPOSE This randomized controlled trial tests the efficacy of bilateral arm training with rhythmic auditory cueing (BATRAC) versus dose-matched therapeutic exercises (DMTEs) on upper-extremity (UE) function in stroke survivors and uses functional magnetic resonance imaging (fMRI) to examine effects on cortical reorganization. METHODS A(More)
BACKGROUND AND PURPOSE Chronic upper extremity hemiparesis is a leading cause of functional disability after stroke. We investigated the hypothesis that bilateral arm training with rhythmic auditory cueing (BATRAC) will improve motor function in the hemiparetic arm of stroke patients. METHODS In this single group pilot study we determined the effects of 6(More)
CONTEXT Reorganization in central motor networks occurs during early recovery from hemiparetic stroke. In chronic stroke survivors, specific rehabilitation therapy can improve upper extremity function. OBJECTIVE To test the hypothesis that in patients who have chronic motor impairment following stroke, specific rehabilitation therapy that improves arm(More)
OBJECTIVE To compare the efficacy of treadmill exercises and stretching and resistance exercises in improving gait speed, strength, and fitness for patients with Parkinson disease. DESIGN A comparative, prospective, randomized, single-blinded clinical trial of 3 types of physical exercise. SETTING The Parkinson's Disease and Movement Disorders Center at(More)
It was shown recently that functional activation across brain motor areas during locomotion and foot movements are similar but differ substantially from activation related to upper extremity movement (Miyai [2001]: Neuroimage 14:1186-1192). The activation pattern may be a function of the behavioral context of the movement rather than of its mechanical(More)
BACKGROUND AND PURPOSE Stroke often impairs gait thereby reducing mobility and fitness and promoting chronic disability. Gait is a complex sensorimotor function controlled by integrated cortical, subcortical, and spinal networks. The mechanisms of gait recovery after stroke are not well understood. This study examines the hypothesis that progressive(More)
BACKGROUND Cognitive deficits impede stroke recovery. Aerobic exercise (AEX) improves cognitive executive function (EF) processes in healthy individuals, although the learning benefits after stroke are unknown. OBJECTIVE To understand AEX-induced improvements in EF, motor learning, and mobility poststroke. METHODS Following cardiorespiratory testing, 38(More)
This pilot study evaluated the safety and feasibility of a 3-month progressive treadmill aerobic exercise (TM-AEX) program for persons with Parkinson disease with gait impairment. Eight subjects underwent a treadmill stress test to determine eligibility. Of these subjects, three were referred for further cardiac evaluation and five were enrolled. In 136(More)
OBJECTIVE Hemiparetic gait is characterized by high stride-cycle variability, diminished stance time, single-limb stance time, and stance/swing ratio in the paretic limb. Recent studies suggest treadmill (TM) training may improve the motor control underlying these variables, but supporting evidence is sparse. METHODS This study compared gait patterns of(More)
