Detection of EMG activity using sensors on both sides of the body

摘要

A monitoring system may include each of a left and a right side EMG detection device and may be configured to detect either seizure activity associated with the left side or right side of a patient's body. The system may further be configured to differentiate symmetric or asymmetric seizure activity. For example, the system may characterize whether left and right side EMG detectors show similar or dissimilar levels of activation during a suspected seizure. In some embodiments, the system may also include one or more orientation and/or position sensors. The system may be configured to determine the orientation and position of the sensor over time and to correlate this data with EMG signals.

1. A method of monitoring a patient for seizure activity comprising:
placing a first detection unit including a first EMG sensor over a muscle located on a left side of said patient's body; placing a second detection unit including a second EMG sensor over a muscle located on a right side of said patient's body; wherein said first detection unit includes a first pressure sensor; wherein said second detection unit includes a second pressure sensor; collecting and analyzing an EMG signal from each of said first EMG sensor and said second EMG sensor; collecting first pressure sensor data using said first pressure sensor; collecting second pressure sensor data using said second pressure sensor; determining whether either of said first pressure sensor data or said second pressure sensor data indicates that a weight of said patient is pressed against one of said first pressure sensor or said second pressure sensor; and initiating a response if the EMG signal from either said first EMG sensor or said second EMG sensor indicates occurrence of a seizure.
