Blink reflexes elicited by electrical stimulation of the supraorbital nerves, by monoaurally presented 1 kHz sine wave bursts of 20-ms duration, and by flashes of light presented monocularly were investigated in 32 healthy controls. Absolute latencies of the individual components and side differences were measured. An outline of possible anatomical pathways(More)
The prevalence of clinical and electrophysiological signs of peripheral nerve disease was evaluated in 151 patients with chronic obstructive pulmonary disease. Patients with concomitant disorders affecting the peripheral nervous system were excluded. Thirty patients had clinical signs of a mild sensorimotor and distal neuropathy and 13 additional patients(More)
A peculiar form of chronic spinal muscular atrophy is described, 5 unrelated young males developed muscle wasting of the left shoulder and upper arm region, mainly in the distribution of myotomes C5 and C6. This muscle atrophy remained confined to the primary site for 13-18 years, being followed in 4 cases by a mild muscle atrophy of the right upper arm or(More)
Pattern shift visual evoked potentials were investigated in 9 subjects with Charcot-Marie-Tooth disease, who were classified as HMSN I on clinical, genetic and electromyographic criteria. The latency of the second positive peak was increased in 7 eyes of 5 subjects. These results suggest that patients with HMSN I the optic nerves may be affected more(More)
Nerve conduction was studied in various sensory and motor leg nerves in diabetics. Distal nerves were more affected than proximal ones. There was a poor correlation between neurographic results and the severity of clinical symptoms. No relationship was found between the degree of alteration of the individual neurographic parameter and the duration of(More)
Orthodromic and antidromic nerve conduction velocities were determined in sensory median nerve fibres from digit to palm and from palm to wrist in patients with the carpal tunnel syndrome. In a large number of subjects the carpal tunnel syndrome could be detected only when the palm-to-wrist segment was investigated. Comparison of the results of the(More)
Fibre density and amplitudes of macro-EMG motor unit potentials were studied and compared with conventional EMG in the anterior tibial muscles from 51 patients with amyotrophic lateral sclerosis. The fibre density was increased in 46 muscles. Increased amplitudes of macro-EMG motor unit action potentials were found in 46 muscles, while the mean duration of(More)
The bulbocavernosus reflex (BCR) was examined in 39 normal potent men and in 252 patients with impaired potency of varying aetiology. For BCR evaluation minimum, maximum and mean latencies, the temporal dispersion in ten successive responses, together with minimum and maximum side differences from simultaneous recordings of the left and right(More)
Acute trichinosis can be followed by a chronic stage. Myalgia is the main clinical symptom in the chronic course of the disease. From 19 patients with a history of acute trichinosis 2-42 years ago, 15 patients suffered from chronic myalgia. Other typical complaints of our patients in the chronic stage were opthalmodynia, burning of the eyes, headache and(More)
