EMG is usually measured by calculating the difference between two electrodes. At TMSi we have different electrodes available with different advantages.
The snap-electrodes are very easy to handle, enabling you to very quickly set-up an EMG measurement using the pre-gelled disposable electrodes. The disposable electrodes have a measurement surface of about 12mm.
The micro-electrodes are a bit harder to handle, but their small measurement surface of about 1mm enables you to measure EMG of small muscles. The small measurement surface makes the skin movement artifacts much smalles, as well as the crosstalk.
