Abstract:
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.
