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)
The principle of the static charge-sensitive-bed (SCSB) method is described. The method is simple and inexpensive. From the SCSB recording the ballistocardiogram (BCG) and respiratory movement can be simultaneously recorded by selective filtering of the original signal. The SCSB recording thus enables continuous long-term monitoring of the BCG, heart rate,(More)
The role of enlarged adenoids and tonsils in recurrent respiratory infections and upper airway obstruction has become well-established earlier. In this study we investigated the relationship between the X-ray properties of the nasopharynx and the sleep quality by using a new sleep registration method: The Static Charge Sensitive Bed (SCSB). The estimation(More)
We evaluated the autonomic influence on balistocardiograms recorded by a static-charge-sensitive bed for cardiovascular monitoring in nine healthy males (20-44 years) and its clinical use in 11 patients who underwent coronary bypass surgery (51-59 years). The ballistocardiogram displayed a distorted low amplitude from the empty beating heart during bypass(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)
PURPOSE To evaluate the usefulness of intravenous patient-controlled analgesia (PCA) fentanyl for labour analgesia, its effectiveness for maternal pain and safety for the fetus and newborn. METHODS Twenty primigravidas were randomised to receive intravenous PCA fentanyl or epidural analgesia for labour pain. Maternal pain, heart rate and arterial(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)
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)

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)
