Method and apparatus for detecting seizures

摘要

A method of detecting seizures may comprise receiving an EMG signal and processing the received EMG signal to determine whether a seizure characteristic is present in the EMG signal during a time window. An apparatus for detecting seizures with motor manifestations may comprise one or more EMG electrodes capable of providing an EMG signal substantially representing seizure-related muscle activity; and a processor configured to receive the EMG signal, process the EMG signal to determine whether a seizure may be occurring, and generate an alert if a seizure is determined to be occurring based on the EMG signal.

主权项

1. A system of apparatuses for monitoring a patient for seizure activity, the system comprising:
one or more electromyography electrodes configured to provide an electromyography signal; a processor configured to receive the electromyography signal and process the electromyography signal to detect bursts characteristic of seizure activity based on whether regions of the electromyography signal meet criteria suitable to be qualified as bursts, including a comparison of criteria values to thresholds; wherein said criteria values include a duration width and one or more of a signal-to-noise ratio and an amplitude; wherein said thresholds include a minimum duration width, a maximum duration width, and one or more of a minimum signal-to-noise ratio, minimum amplitude, and maximum amplitude; and wherein said processor is configured to determine a detected burst count and include said detected burst count in a determination of whether to send an alert indicating detection of said seizure activity to one or more remote devices.
