Nine parkinsonian patients were studied during one night using the static charge sensitive bed (SCSB) method for the monitoring of respiration, ballistocardiogram (BCG) and body movements. The parkinsonian sleep was more restless than that of the controls. As the SCSB-defined levels of autonomic nervous activity were concerned, the amount of motor active(More)
To investigate the nocturnal motor activity associated with teethgrinding, 12 patients and 12 controls were recorded during sleep with the masseter muscle electromyogram (EMG) and the static charge-sensitive bed movement sensor. The frequency of body movements per hour was 21.4 in the teethgrinders and 14.0 (P less than .05) in the control group. The(More)
The principle of 'a static charge sensitive bed' method for recording body movements during sleep is described. We made records during 30 nights and the measured total number of movements per night (80-200) is in agreement with the findings of studies based on a combination of direct observation, EMG and videotape. The method is simple, inexpensive and very(More)
A new method for long-term monitoring of respiration, the ballistocardiogram (BCG), heart rate and body movements in newborn infants and children is presented. The design of the static charge-sensitive bed (SCSB) method for the monitoring of newborn infants and children is described. The method is simple and inexpensive. No electrodes or cables need to be(More)
Heavy snoring is associated with increased respiratory variation of the ballistocardiogram (BCG). The cause for this association is not known. Although the BCG is a sensitive method to measure myocardial performance, the validity of the signal as a marker of snoring-related haemodynamic changes has not been tested. The aim of this study was to investigate(More)

During paradoxical sleep, single unit activity was recorded from the posterior part of the middle suprasylvian cortex together with the electrical activity of the medial rectus eye muscles and that of the pulvinar nucleus. Experiments were performed on unrestrained cats, which slept in a dark cage. The intervals between the onsets of the successive phasic(More)
Alertness and sleep in healthy young men conscripted into military service were examined by testing personality characteristics and by completing questionnaires at the beginning of military service about their civilian life alertness and sleep, and by using polygraphic recordings during their military service. Sleep-time during service was restricted to 8(More)
In a double-blind crossover study, the pharmacokinetics and effects on night-time respiration and body movements of midazolam 7.5 mg, flunitrazepam 1 mg, and placebo were studied in 5 elderly insomniac patients with the static charge sensitive bed-method (SCSB). In a supine position, the gastrointestinal absorption rate of flunitrazepam (tmax 0.6 h) was(More)
