The aim of the present study was to evaluate the prevalence of latent and manifest suprascapular neuropathy in high-level male volleyball players. Thirty subjects were examined clinically and electrophysiologically. Suprascapular neuropathy, most probably at the level of the suprascapular notch, was demonstrated in 12 subjects, being latent in eight. Taking(More)
It is well known that transcranial stimulation, delivered during sustained muscle contraction, evokes a temporary suppression of motor activity (silent period). The aim of the present study was to further analyze this inhibition in 20 healthy subjects and in 10 patients with previous stroke. Transcranial magnetic stimulation was performed at the vertex,(More)

A 25-year-old semi-professional dancer developed painless, isolated weakness of external rotation of the right arm. Physical examination was otherwise normal. Electromyography showed selective partial denervation of the infraspinatus muscle. Stimulation of the suprascapular nerve at Erb's point demonstrated delayed conduction to the infraspinatus muscle.(More)
High intensity transient signals (HITS) have been identified ultrasonically in patients with extracranial vascular or cardiac disease and are suggestive of microembolic material. We studied the prevalence of these signals in 60 patients with increased risk for cardioembolic stroke and in a control group of 20 subjects. Patient groups (n = 20) were(More)
In muscles with sustained voluntary contraction, EMG activity is transiently inhibited after transcranial magnetic stimulation. We recorded this postexcitatory silent period (SP) at 1.5 times individual stimulus threshold level from the first dorsal interosseus muscle in 65 neurologic patients aged 11 to 80 years. When compared with 20 healthy volunteers(More)

Analysis of motor evoked potentials (MEP) after magnetic brain stimulation is often restricted to measurement of latency and amplitude. In the present study, which was conducted in healthy controls and in patients with multiple sclerosis (MS), the additional value of MEP duration and configuration was evaluated. Recordings were made from distal muscles of(More)

In a patient with adrenoleukodystrophy (ALD), prolonged conduction times along the corticospinal tract and afferent sensory pathways were demonstrated using magnetic transcranial brain stimulation and multimodality evoked potentials, respectively. On investigation of two healthy family members (one an obligate carrier), slight latency increases in evoked(More)
