Daytime sleepiness is common in myotonic dystrophy and might be attributed to disturbed nocturnal breathing. Seventeen out of 22 patients complained of excessive daytime sleepiness, resembling "idiopathic hypersomnolence". Sleep apnoea might have contributed to daytime sleepiness in only three of 17 patients. Treatment with the central stimulant(More)
In 80 controls latencies of flexor carpi radialis (FCR) and in 94 controls latencies of soleus H-reflexes correlated well with length of the extremity, body height and age. Multiple regression equations using latency as a variable dependent on age and body height can be best used in practice when both reflexes are employed for demonstration of proximal(More)
We prospectively studied the reliability and accuracy of the electroencephalogram as a predictor of the risk of recurrence within 2 years in 157 patients with untreated idiopathic first seizures. In all patients, a standard electroencephalogram and, if necessary, an electroencephalogram after partial sleep deprivation were obtained. All(More)
In 143 normal subjects latencies of H-reflexes of the flexor carpi radialis muscle were well correlated with arm lengths. In 32 patients with injury to cervical roots C5 to C8 it was shown that latencies were only abnormal in lesions of roots C6 or C7. It is suggested that in most instances root C6 or C7 and, probably both roots in some cases are involved(More)
Degenerative cervical radiculopathy: clinical diagnosis and conservative treatment. A review. To provide a state-of-the-art assessment of diagnosis and non-surgical treatment of degenerative cervical radiculopathy a literature search for studies on epidemiology, diagnosis including electrophysiological examination and imaging studies, and different types of(More)
H-reflexes of the flexor carpi radialis muscle were studied in 52 controls and 25 cancer patients with radiation-induced brachial plexopathy. It was found that H-reflex conduction velocity (H-RCV) decreased with increasing age. This was not true for H-reflex latency (H-RL) and inter-latency times. There were no H-RCV and latency differences between(More)
The Sleep Disorders Questionnaire (SDQ) is a 176-item questionnaire designed to diagnose the presence of common sleep disorders. This study set out to assess the validity of a Dutch translation of the SDQ. Scores on 145 questionnaires were analyzed. A cluster analysis of these scores revealed the following clusters: healthy, depression, insomnia,(More)
The vestibular function was extensively investigated in 75 patients suffering from migraine. Pathological findings were present in 62 patients (82.6%). With the exception of position nystagmus, vestibular abnormalities were not related to migraine characteristics. Fifty-six patients were treated with flunarizine 10 mg daily for three months. A favourable(More)
Peak latencies of somatosensory evoked potentials (SEPs) from nerves of the first digit (digit 1-SEP), 39 controls, and third digit (digit 3-SEP), 47 controls, and indicated for Erb's point, second cervical vertebra (Cv2) and contralateral cortical hand area correlated significantly with arm length. Single regression analysis for arm length for Erb's(More)
BACKGROUND AND PURPOSE We initiated this prospective study to investigate the usefulness of contrast enhancement in combination with color Doppler-assisted duplex imaging (CDDI) for the distinction of subtotal internal carotid artery (ICA) stenosis and ICA occlusion. METHODS During 1 year all patients with a previously unknown subtotal ICA stenosis (>90%)(More)
