EMG

The Granata Lab has a telemetry based surface based EMG system from Delysis (Natick, MA), which is comprised of 12 EMGs.  This telemetered system allow for the collection of EMG data without having the subject connected directly to the computer during testing, with each EMG being a roughly 1 inch square block in size. Each EMG is also an IMU, therefore it is capable of collecting muscle electrical activity, linear acceleration, angular acceleration, and magnetometer information.  This system allows for much easier data collection during all tasks, but specifically during more dynamic tasks such as running, cutting and jumping.  The EMG system can be used in isolation or can be integrated and time synchronized with the motion capture, force plate, and pedar-X systems depending on the research question.
