I just got pointed to a video that seems relevant to the EMG/EKG lab:
For those without the patience to watch a 76-second video, it shows the use of 20 EMG channels from skin electrodes being used to control musical instruments (mostly percussion). It probably takes some practice to be able to control each of the muscles independently with enough precision to play music, as the muscles involved are mostly large ones.
This video might be a good one to show as an introduction to the EMG/EKG lab.
[...] showed the Old Spice ad that demonstrates skin-electrode EMG (which I mentioned in an earlier blog post), then started talking about EKGs. We started with the need to have current-limiting resistors to [...]
