Method for detecting seizures

摘要

A method and system for detecting seizures onset comprising a measuring unit (1) having one or more sensors for detecting the electromyographic signal of one ore more musc of the user. The sensors are connected to a pre processing module (3) comprising a high-pass filter which filters out noise and motion artefacts related to normal musc activities. The pre-processing module is connected to a feature extraction module (4) comprising a threshold detector which counts the number of zero-crossings with a hysteresis within a predetermined time window. The feature extraction module is connected to a c module (5) which compares the extracted features to a first and second threshold and generates an event signal if the extracted features are above the first and second threshold.
