BACKGROUND Functional neuroimaging studies show adaptive changes in areas adjacent and distant from the stroke. This longitudinal study assessed whether changes in cortical excitability in affected and unaffected motor areas after acute stroke correlates with functional and motor recovery. METHODS We studied 13 patients with moderate to severe hemiparesis(More)
Seric IgM autoreactivity in 100 multiple sclerosis (MS) and 106 control (70 of whom had other neurological diseases) patients was assessed either by immunohistochemistry on normal human CNS tissue or to GD2, GD1a, GD3 by ELISA and thin layer chromatography (TLC) techniques. By double immunohistochemistry, we found that 44% of the total MS population showed(More)
OBJECTIVE To investigate blood oxygenation level-dependent (BOLD) activation during somatosensory electrical stimulation of the median nerve in acute stroke patients and to determine its correlation with ischemic damage and clinical recovery over time. METHODS Fourteen acute stroke patients underwent functional magnetic resonance imaging (fMRI) during(More)
OBJECTIVE Whereas several studies have used functional magnetic resonance imaging (fMRI) to investigate motor recovery, whether therapy to decrease post-stroke hypertonus alters central motor patterns remains unclear. In this study, we used continuous electromyography (EMG)-fMRI to investigate possible changes in movement-related brain activation in(More)
Motor excitability is increased in both hemispheres in stroke patients during motor recovery. Pharmacologically controlled changes of cortical excitability might be beneficial for synaptic plasticity and therefore facilitate functional recovery after a brain lesion. In particular, it has been suggested that antidepressant drugs can modulate motor(More)
Passive electrical stimulation activates various human somatosensory cortical systems including the contralateral primary somatosensory area (SI), bilateral secondary somatosensory area (SII) and bilateral insula. The effect of stimulation frequency on blood oxygenation level-dependent (BOLD) activity remains unclear. We acquired 3-T functional magnetic(More)
PURPOSE Post-polio syndrome develops about 20-40 years after acute paralytic poliomyelitis, and manifests with progressively deteriorating muscle strength and endurance. Here, we assessed whether transcranial direct current stimulation (tDCS) improves sleep and fatigue symptoms in patients with post-polio syndrome. METHODS We enrolled 32 patients with a(More)
The aim of the present study was to compare the EEG signal recorded outside and inside a 1.5T magnetic resonance (MR) scanner. The EEG was recorded in eyes open and eyes closed conditions using a digital recording MR-compatible system. To characterize how a static magnetic field induces changes in EEG signal, EEG data were analyzed using FFT frequency(More)
OBJECTIVE The aim of this study was to investigate the effect of botulinum toxin type A injection into the adductor muscles in reducing pain and improving joint mobility and quality of life in patients affected by hip osteoarthritis. METHODS A total of 39 outpatients, mean age 68 years (age range 41-82 years), were evaluated using the Harris Hip Score to(More)
PURPOSE Promising new rehabilitative approaches to improve the substantial motor disability associated with chronic stroke include pharmacotherapy to enhance motor recovery. We conducted a single-blind placebo-controlled crossover pilot study to investigate the effects of prolonged treatment with L-DOPA in stroke patients. METHODS Ten chronic (10-48(More)
