Method and apparatus for detecting seizures

摘要

A method and apparatus for detecting seizures with motor manifestations including detecting EMG signals, isolating from the EMG signals spectral data for a plurality of frequency bands, and calculating a T-squared value there from. The T-squared values may be detected in real time, such as in a patient's home environment, and the T-squared data may be compared to a threshold T-squared value to determine whether an alarm is sent.

1. A system for monitoring a patient for seizure activity comprising:
a detection unit mountable to said patient, the detection unit comprising:
one or more electromyography electrodes configured to provide an electromyography signal representing seizure-related muscle activity;a first processor in communication with said one or more electromyography electrodes, said first processor configured to receive said electromyography signal, determine electromyography data from said electromyography signal, and process said electromyography signal to determine whether said seizure activity is occurring; anda transceiver in communication with said first processor, said transceiver configured to receive said electromyography data and to transmit said electromyography data if the first processor determines that said seizure activity is present; a base station configured to receive said electromyography data from said transceiver; one or more environmental transceivers associated with one or more objects present within a home setting for said patient, each of said one or more environmental transceivers being configured to transmit a proximity signal to said base station, the proximity signal being dependent upon whether a respective environmental transceiver among said one or more environmental transceivers is within an operating distance from said detection unit; and said base station comprising a second processor configured for:
processing said proximity signal dependent upon whether the respective environmental transceiver among said one or more environmental transceivers is within an operating distance from said detection unit;based on said proximity signal, selecting a first template file among a plurality of template files, each of said plurality of template files including one or more seizure detection threshold settings;processing said electromyography data based on said one or more seizure detection threshold settings included in said first template file applied to confirm the presence of said seizure activity; andinitiating transmission of an alarm to a remote caregiver if said seizure activity is confirmed.
