BACKGROUND Physical training might delay the functional deterioration caused by disuse in boys with Duchenne muscular dystrophy (DMD). The "No Use Is Disuse" study is the first explorative, randomized controlled trial in boys with DMD to examine whether assisted bicycle training is feasible, safe, and beneficial. METHODS Ambulatory and recently(More)
On investigation of 101 attacks in 24 patients with hereditary neuralgic amyotrophy (HNA) from nine different families, we found that HNA can run two distinct courses: a 'classic' relapsing-remitting and a chronic undulating type with exacerbations. Only one type occurred per family, suggesting genetic heterogeneity. This is supported by the finding that(More)
OBJECTIVE Ehlers-Danlos syndrome (EDS) is a clinically and genetically heterogeneous group of heritable connective tissue disorders characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. Muscle involvement is plausible based on recently discovered interactions between muscle cells and extracellular matrix molecules; however,(More)
INTRODUCTION Effects of systemic inflammation on cerebral function are not clear, as both inflammation-induced encephalopathy as well as stress-hormone mediated alertness have been described. METHODS Experimental endotoxemia (2 ng/kg Escherichia coli lipopolysaccharide [LPS]) was induced in 15 subjects, whereas 10 served as controls. Cytokines (TNF-alpha,(More)
Neuralgic amyotrophy--also known as Parsonage-Turner syndrome or brachial plexus neuritis--is a distinct and painful peripheral neuropathy that causes episodes of multifocal paresis and sensory loss in a brachial plexus distribution with concomitant involvement of other PNS structures (such as the lumbosacral plexus or phrenic nerve) in a large number of(More)
Responsive outcome measures are needed to follow the disease status of Duchenne muscular dystrophy (DMD) patients, as new therapeutic approaches become available for affected boys. Quantitative muscle ultrasound (QMUS) is potentially an attractive follow up tool for DMD because it reflects the severity of the dystrophic process without the need for invasive(More)
Thirteen classical ataxia telangiectasia (A-T) patients, varying in age from 1 to 25 years, were studied clinically, electrophysiologically as well as by muscle ultrasound to chart the development and spectrum of neuromuscular abnormalities in A-T. The most prominent finding was a progressive axonal sensorimotor polyneuropathy, apparent by electromyography(More)
BACKGROUND In autosomal dominant cerebellar ataxias (ADCAs), it is unclear whether the associated peripheral nerve involvement is always a typical length-dependent axonopathy rather than primary neuronopathy due to neuronal degeneration in the spinal anterior horns and/or dorsal root ganglia. OBJECTIVE To study the nature and extent of peripheral nerve(More)
We investigated the symptoms, course and prognosis of neuralgic amyotrophy (NA) in a large group of patients with idiopathic neuralgic amyotrophy (INA, n = 199) and hereditary neuralgic amyotrophy (HNA, n = 47) to gain more insight into the broad clinical spectrum of the disorder. Several findings from earlier smaller-scale studies were tested, and for the(More)
