If the EMG signal or baseline is noisy, check the following:

1. Ensure good connection from the EMG sensor to the electrode.

If using Ultium EMG, ensure the lead is connected to the sensor, and the leads are properly attached to the electrode.

If using Core EMG, ensure the electrode is properly connected to the back of the Core EMG sensor.

For more information on sensor placement/adherence, reference the EMG Skin Prep, Electrode Placement, and Signal Check Tutorial🔗.

2. Make the checks listed in the Evaluating EMG Signal Quality🔗 document.

Perform the checks listed to check resting baseline noise, signal impedance, and frequency interference.

3. Swap sensors/replace the electrode.

To rule out the possibility the bad signal is related to the sensor or the electrode, swap with another sensor, or replace the electrode.
