    GP4 - 4 Channel Biofeedback System

    I am a Total beginner at EMG. I am learning the piano and have difficulties adopting correct posture of my forearms / wrist. I would like to monitor the tension of agonists / antagonists in my forearms, maybe also shoulders. It is not intended for professional use, purely recreational. So I don’t want to break the bank. The sEMG does have to be able to meet my purposes though. I would like to see a Graphical display of at least two muscle activities. Any advice on which equipment could be useful?

      Th GP device would give you the ability to monitor two muscles at the same time with EMG

    I've used the nexus 4 system for a few years and am looking to expand. This system was recommended. Is it comparable? Can I use accessories for the nexus with it? How user friendly is the software?
    Thank youo

      This product is very different than the Nexus. Contact our sales department to discuss options sales@bio-medical.com or just call the office
