You should record the record the hand dynamometer data, associate them with the EMG data and get a function that predicts the exerted force based on the EMG data, run the test again and compare the values.
I'm not sure what exactly is going on here, but EMG activity should be INCREASING as your arm fatigues. This is because you need more effort to keep your arm up as the your smaller motor units tire out.
yep, amplitude and RMS should spike up during fatigue, that's what I do not understand here! the only thing that decreases are frequency domain features like the MAV and median frequency
@@MrMidouCa I'm pretty sure I know now what I was confused about when I made this comment. Surface EMG doesn't measure neuronal output directly, it's primarily measuring the electrical activity generated by muscle contraction itself. Less muscle contraction (due to fatigue) = lower EMG values Also, muscles tend to produce lower EMG activity as they lengthen, so if your arm starts to drop or your grip starts to loosen that may also contribute to the effect
I'm a biomedical engineer and I think I've found the heaven of youtube channels for my program
I’m BME too, so I can relate LOL

The twitch imposed to peak voluntary force during fatigue zone would show the CENTRAL FATIGUE added.
Hi. I built the circuit with AD620 and it does not work, what would be the reason? thank you
And... this leads to muscle growth?
what app is that?
Can I use ecg electrodes to measure EMG?
Well, yeah, the electrodes themselves don't really matter.
What matters is by how much you amplify your signal.

Why that cockroach 🪳 in the video have only five legs 🤔
