Bipolar EMG Recording
Posted: Fri Oct 29, 2004 5:39 pm
Hi all!
I'm completly new to the BIO-Semi system. I recorded an EMG of the Mm. Orbicularis Oculi (the muscle that closes the eye) for recording eye-blinks (startle-blinks). I placed Ex1&2 under the eye and the two Aux1-Electrodes behind the ear over the bone as a refernce. In the recording software I choose "refernce-free". The eyeblinks have been claerly visible on the "bipolar-leads-Tab" Ex1 vs. Ex2. Fine. But now I want to import the data into BESA. I have no idea how to configure it in BESA, that it will be displayed as a Biploar-EMG-Recording. I had no success playing around in the "monate-menu". Does anyome have an idea how I can disply the data the right way? Or is there a good other software for EMG-Analysis recorded with BioSemi (also for preprocessing of the data like rectification)? Sorry if this question is dump, but it's my first time working with Biosemi & Besa.
