Study Of The Effect Of Fatigue On Human Being By EMG’S Signal Analyzing
Electromyography (EMG) is a medical technique that can record with an electromyograph, electric currents
accompanying muscle activity. And among the medical applications we have the detection of medical abnormalities, activity
level and/or human movement. For our case study we present the latter two applications. The aim of our work is to detect the
amount of muscle’s fatigue after doing an effort using signal processing.
We have recorded an EMG signal related to two situations, the first one is in the normal case (arm muscles are inactive) , the
second one is after doing a job (carrying some books) and by analyzing the two signals we can see the difference and detect the
amount of fatigue of the arm. After running the data processing using Matlab, we got convincing results.
