Thanks a lot for putting out such a knowledgeable presentation and talk for the aspiring researchers in the field of sports sciences.

[@warinkrityakiarana4838]

Very useful information and nice talk... Thank you very much

[@Sakowski_kyokushinway]

Amazing knowledge thank you

[@sumeyyegenc7770]

Thank you very much 👏

[@sucimuqo]

Thank you 👍

I am a sport and exercise student, and watching this video has really given me a better understanding about EMG, for which I am currently writing a report on. Any further help would be amazing

[@salahlah23]

This is gold

[@darelbutler3953]

How to straighten a curvy base, please? I have a green and a red electrode I place on the patient along with a concentric needle

[@mohammadreda8247]

What is the name of the application used for visualizing the reading of the sensor

[@biomechstu]

Hi Mohammad. I believe it was done in Delsys EMGworks, if I have understood your question correctly.

Hello sir, I was praying to god so that the algorithm brings me some answers about emg…
I want to build a project of an arm based on 5 servos…… and a huge ass 350 half a horsepower motor which I’m currently trying to turn it into a servo too😂
The only problem is that i have no idea how to code the EMG and where to put the electrodes, can u help?

[@samuel-br.man__3571]

Having a bigger muscle will help 😂
