Biospecimen Description:
no Biospecimen

Enrollment: 15
Study Start Date: October 2007
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Detailed Description:

Patients undergoing Video-EEG telemetry will wear movement sensor on their wrist. The sensor will transmit continuous data to a laptop. Seizures' data (tonic or clonic) will be analyzed and transformed into an algorithm (up-graded existing preliminary algorithm).

In the second phase the algorithm will need to identify seizure events within one minute of the onset.

Both specificity ("false positive") and sensitivity ("false negative) will be than calculated.
