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 method of detecting seizures comprising:
detecting EMG signals for a time period, the time period comprising a reference period and a monitoring period; using digital filtering to isolate from the EMG signals spectral data for a plurality of frequencies bands selected from the range of about 2 Hz to about 1000 Hz; calculating a first T-squared value, the first T-squared value being determined from spectral data for the plurality of frequency ranges, from at least one part of the reference period; calculating a second T-squared value, the second T-squared value being determined from spectral data for the plurality of frequency ranges, from at least one part of the monitoring period; comparing the second T-squared value to the first T-squared value; and determining whether to trigger an alarm condition using said comparison of the first T-squared value to the second T-squared value.
