Trigno Spring Contact
For indwelling EMG recording
The Trigno™ Spring Contact Adapter gives users the ability to collect indwelling, fine wire EMG through the robust Trigno™ system. Delsys makes no assertions or recommendations on the type of recording electrode to use, or the method of its application. This responsibility befalls the electrode manufacturer, the client performing the study and the Institutional Review Board overseeing the study.
