  • Publication number: 20180000409
    Abstract: Means and methods for measuring pain and adapted for calculating the level of nociception during general anesthesia or sedation from data including electroencephalogram (EEG), facial electromyogram (EMG), heart rate variability (HRV) by electrocardiogram (ECG) and plethysmography by impedance cardiography (ICG). In a preferred embodiment of this invention the parameters derived from the EEG, the HRV, the plethysmographic curve and the analgetics concentrations are either combined into one index on a scale from 0 to 100, where a high number is associated with high probability of response to noxious stimuli, while a decreasing index is associated with decreasing probability of response to noxious stimuli. Zero (0) indicates extremely low probability of response to noxious stimuli. In an alternative embodiment, only features from the EEG and ECG will be used or only features from EEG, ECG and ICG, to define the fmal index.

  • Publication number: 20090326419
    Abstract: The present patent describes a method for a Movement and Vibration Analyzer (MVA) based on Fast Fourier Transform spectral analysis, and empirical mode decomposition (EMD) for Hilbert transform of a timeseries recorded with an accelerometer attached to a human being or an object. The medical application is the detection of Parkinson's disease (PD) and other neurological motor disorders (Dystonias, Dyskinesias, Huntington's disease, Essential Tremor, Multiple System Atrophy (MSA), etc), which affects worldwide more than 5 million persons, where the highest percentage is in the ageing population. The industrial application is the study of vibration and maintenance of rotational devices (motors, turbines, and others which have an intrinsic sinusoidal likewise movement). An EMD is carried out on the acceleration signal which produces a collection of intrinsic mode functions (IMF), on which the Hilbert transform is carried out.
